(d) Default under previous contracts.

(e) Failure to identify a consultant which is properly qualified and listed in the Department's pre-qualified list for the type of work specified.

102.04 Interpretation of Quantities in Proposal. The lump sums bid for design and construction of the project, plus any unit bid prices (multiplied by the appropriate quantity) required in the proposal shall be the sole basis for comparison of bids. These will also be used to determine the progress of the work and to provide guidance in the issuance of partial payments during design and construction. Any quantities appearing in the proposal are approximate only and are prepared for the comparison of bids. The Department does not assume any responsibility that the quantities will actually be required in the project construction, nor will the Contractor be allowed to plead misunderstanding or deception because of the quantity estimate or because of the character of the work, the location, or other conditions.

102.05 Examination of Plans, Specifications, Special Provisions, and Site of Work. The Bidder must examine the site of the proposed work, and the Conceptual Documents, before submitting a proposal. The submission of a bid shall be considered evidence that the Bidder has made such examination and is satisfied as to the conditions to be encountered in performing the work and as to the requirements of the Conceptual Documents.

Reference to standards, specifications, manuals or codes of any technical society, organization or association, or to the Laws or Regulations of any governmental authority, whether such reference be specific or by implication, shall mean the latest standard, specification, manual, code or Laws or Regulations in effect on the last day for receipt of Proposals except as may be otherwise specifically stated in the Contract Documents.

102.06 Preparation of Proposal. The Bidder shall submit his proposal upon the forms furnished by the Department. However, a computerized bid form approved by the Department may be attached to the bid proposal in lieu of completing the printed estimated quantities in the bidding documents. The Bidder shall specify a unit price in figures for each pay item for which a quantity is given or a complete price for any item which is designated a lump sum and shall also show the products of any respective unit prices and quantities written in figures in the column provided for that purpose and the total amount of the proposal obtained by adding the amounts of the several items. All the words and figures shall be in ink or typed.

When an item in the proposal contains a choice to be designated by the Bidder, the Bidder shall indicate his choice in accordance with the specifications for that particular item , and thereafter no further choice will be permitted.

The proposal shall include a properly executed Noncollusion Affidavit.

The Bidder's proposal must be signed with ink by the individual, by one or more members of the partnership, by one or more members or officers of each firm representing a joint venture, or by one or more officers of a corporation, or by an agent of the Bidder legally qualified and acceptable to the State. If the proposal is made by an individual, his name and business address must be shown; by a partnership, the name and business address of each partnership member must be shown; as a joint venture, the name and business address of each member or officer of the firms represented by the joint venture must be shown; by a corporation, the name of the state under the laws of which the corporation is chartered and the name and title of the officer or officers having authority under the bylaws to sign contracts, the name of the corporation and the business address of its corporate officials must be shown.

Anyone signing a proposal as agent must file with it legal evidence of his authority to do so.

102.07 Irregular Proposals. Proposals will be considered irregular and may be rejected for the following reasons:

(a) If the proposal is on a form other than that furnished by the Department; or if the form is altered or any part thereof is detached. Computer generated facsimiles of the Department's format are acceptable.

(b) If there are unauthorized additions, conditional or alternate bids, or irregularities of any kind which may tend to make the proposal incomplete, indefinite, or ambiguous as to its meaning.

(c) If the Bidder adds any provisions reserving the right to accept or reject an award, or to enter into a contract pursuant to an award. This does not exclude a bid limiting the maximum gross amount of awards acceptable to any one Bidder at any one bid letting, provided that any selection of awards will be made by the Department.

(d) If the proposal does not contain a unit price for each pay item listed except in the case of authorized alternate pay items or lump sum items.

(e) If the Department determines that any of the unit bid prices are significantly unbalanced to the potential detriment of the Department.

(f) If the proposal is not properly signed.

g) If the proposal is not typed or in ink.

102.08 Proposal Guaranty. No proposal will be considered unless accompanied by a guaranty of the character and in an amount not less than the amount indicated in the proposal form made payable to the Director of Transportation, in accordance with 5525.01 to 5525.15, ORC.

102.09 Delivery of Proposals. The proposals for each project shall be placed, together with the proposal guaranty, in a sealed envelope so marked as to indicate the identity of the project and the name and address of the Bidder. If forwarded by mail said envelope shall then be placed in another envelope which shall be sealed and addressed as indicated in the proposal. Proposals will be received until the hour and date set for the opening thereof and must be in the hands of the official indicated by such time. Proposals received after the time for opening of bids will be returned to the Bidder unopened.

102.10 Withdrawal of Proposals. A Bidder may withdraw a proposal, provided the request in writing is in the hands of the official indicated in the proposal by the time set for opening proposals. When such request is received, the proposal will be returned to the Bidder unopened. Withdrawal of proposals pursuant to 5525.01 ORC is also available.

102.11 Combination or Conditional Proposals. If the Department so elects, proposals may be issued for projects in combination and/or separately, so that bids may be submitted either on the combination or on separate units of the combination. The Department reserves the right to make awards on combination bids or separate bids to the best advantage of the Department. No combination bids, other than those specifically set up on the proposals by the Department, will be considered. Separate contracts will be written for each individual project included in the combination.

102.12 Public Opening of Proposals. Proposals will be opened and read publicly at the time and place designated by the Director. Bidders, their authorized agents, and other interested parties are invited to be present.

102.13 Disqualification of Bidders. Any of the following reasons may be considered as being sufficient for the disqualification of a Bidder and the rejection of his proposal or proposals:

(a) More than one proposal for the same work from an individual, firm, or corporation under the same or different name.

(b) Evidence of collusion among Bidders. Participants in such collusion will receive no recognition as Bidders for any future work of the Department until any such participant shall have been reinstated as a qualified Bidder.

(c) Bid prices which obviously are materially unbalanced. Mathematically unbalanced bid prices are those that do not reasonably reflect the cost of the item bid, inclusive of labor, profit, overhead and material costs. Some examples of a mathematically unbalanced bid are 'front-end loading' and 'covering' (moving money from one item to another). Bidders must bid at least the cost of the materials for every item bid. Rejection of a bid will result if the Department determines that the bid prices submitted are 'materially unbalanced'. A bid is materially unbalanced if there is a reasonable doubt that the award to the bidder submitting the mathematically unbalanced bid will result in the lowest ultimate cost to the Department.

102.14 Material Guaranty. Before any contract is awarded, the Bidder may be required to furnish a complete statement of the origin, composition, and manufacture of any or all materials to be used in the construction of the work together with samples, which samples may be subjected to the test provided for in these specifications to determine their quality and fitness for the work.


103.01 Consideration of Proposals. After the proposals are opened and read, they will be compared on the basis of the summation of all lump sums bid.

The right is reserved to reject any or all proposals, to waive technicalities or to advertise for new proposals, if in the judgment of the awarding authority the best interests of the Department will be promoted thereby.

103.02 Award of Contract. The award of contract, if it be awarded, will be made within 10 calendar days after the opening of proposals to the lowest or best Bidder whose proposal complies with all the requirements prescribed. In no case will an award be made until all necessary investigations are made as to the responsibility of the Bidder to whom it is proposed to award the contract. The successful Bidder will be notified, by letter mailed to the address shown on his proposal, that his bid has been accepted and that he has been awarded the contract.

In cases where the estimate is not confidential, no award will be made for a sum greater than the estimated cost of the improvement plus 5 percent of such estimated cost. Where the estimate is confidential the award may be made under the provisions of 5525.15 ORC. Where bids are taken in the form of separate proposals on portions of one project, the work will ordinarily be awarded to the Contractor, otherwise qualified, whose combined bid is the lowest. No Contractor bidding on all such proposals shall be required to enter into a contract covering less than the entire project without his consent.

103.03 Cancellation of Award. The Department reserves the right to rescind the award of any contract at any time before the execution of said contract by all parties without any liability against the Department.

103.04 Return of Proposal Guaranty. All proposal guaranties, in the form of a certified check or cashier's check, except those of the three lowest Bidders, will be returned immediately following the opening and checking of the proposals. The retained proposal guaranties of the unsuccessful Bidders, in the form of a certified check or cashier's check, will be returned within 10 days after the date on which the bids are opened. The proposal guaranty of the successful Bidder, if certified check or cashier's check, will be returned after a properly executed contract, performance bond, payment bond and other contract documents have been furnished, and the contract has been executed by the Director. Bid bonds will not be returned because they automatically expire.

103.042 Progress Schedule. Prior to execution of the contract and within 10 days of receiving notice of award, the successful bidder shall furnish a Progress Schedule as required in the Design-Build Scope Of Services.

Controlling items of work are those which specifically and directly control the completion of the project (or which control partial completion, lane closures and lane openings which are specified in the proposal or scope of services).

Time extensions will only be considered when controlling items of work on the Progress Schedule are affected due to no fault of the contractor.

When additional work is required, time extensions will only be granted for controlling items on the Progress Schedule.

Additional requirements are listed in the Design-Build Scope Of Services.

103.05 Requirement of Contract Bond. Prior to execution of the contract, and within 10 days of receiving Notice of Award, the successful Bidder shall furnish a contract performance bond and a payment bond, each to be in an amount equal to the Department's estimate, in accordance with the requirements of 5525.16 ORC on the prescribed form for approval by the Director.

103.06 Execution of Contract. The contract shall be signed by the successful Bidder and returned, together with the certificate of compliance from the Industrial Commission, contract bond and other required contract documents, within 10 days after the Bidder has received notice that the contract has been awarded. No proposal shall be considered binding upon the State of Ohio until the execution of the contract. If the contract is not executed by the Director within 20 days following receipt from the Bidder of the required contract documents, the Bidder will have the right to withdraw his bid without prejudice.

103.07 Failure to Execute Contract. Failure to execute the contract and file acceptable bonds shall be just cause for the cancellation of the award and the forfeiture of the proposal guaranty which shall become the property of the Department, not as a penalty, but in liquidation of damages sustained. Award may then be made to the next lowest responsible Bidder, or the work may be re-advertised and constructed under contract or otherwise, as the Director may decide.

104.02 Differing Site Conditions, Suspension of Work and Significant Changes in the Scope of Work.

(a) Differing Site Conditions Clause

1. Should the Contractor encounter subsurface or latent physical conditions at the site differing materially from those indicated in the conceptual documents, contractual documents, ancillary documents or the contractor's design investigations or unknown physical conditions at the site, of an unusual nature, differing materially from those ordinarily encountered and generally recognized as inherent in the work provided for the contract, the Contractor shall promptly notify the Engineer in writing of the specific differing conditions before they are disturbed or the affected work is performed.

2. Upon written notification, the Engineer will promptly investigate the conditions.

a) If the Engineer determines that the differing site conditions are not anomalous for this area and type of work, even though they may not have been visible or indicated by soil borings or other investigations performed, or which reasonably should have been performed, the Engineer will require the Contractor to make appropriate changes to the design and construction which will assure the integrity and quality of the completed project. No adjustment of contract cost or time required for performance of added or changed work shall be permitted for this purpose. Anomalous is defined as a condition, or set of independent conditions, which typically do not occur.

b) If the Engineer determines that the differing site conditions are an anomaly for this area and type of work, that they were not visible or indicated by soils borings or other investigations performed or which reasonably should have been performed and that the conditions do materially differ and cause an increase or decrease in the cost or time required for the performance of any work under the contract, an equitable adjustment will be made. Should the Engineer and the Contractor disagree, disputes will be resolved in accordance with 105.17

3. No Contract adjustment for the benefit of the Contractor will be allowed unless the Contractor has given the written notice required.

(b) Suspension of Work

1. The Engineer reserves the right to suspend all or any portion of the work for any reasons during the execution of the work.

The request shall include the justification for adjustment.

2. Upon receipt, the Engineer will consider the Contractor's request. If the Engineer agrees that the cost and/or time required for the performance of the contract has increased as a result of such suspension and was caused by conditions beyond the control of and not the fault of the Contractor, suppliers, subcontractors, or by weather the Engineer will make an equitable adjustment (excluding profit) and modify the contract in writing accordingly.

3. No contract adjustment will be allowed unless the Contractor has submitted a request for adjustment within the time prescribed.

104.03 Extra Work. The Contractor shall perform unforeseen work, for which there is no price included in the contract, whenever it is deemed necessary or desirable in order to complete fully the work as contemplated. Such work shall be performed in accordance with the specifications and as directed . No adjustment of the contract cost or the time required for performance of added or changed work will be permitted unless the Contractor demonstrates to the satisfaction of the Engineer that:

a. The need for the extra work was not reasonably evident during the design by inspection or investigations which were performed, or reasonably should have been performed during the design process, and

b. The need for the extra work is anomalous for this area and type of project

If the Engineer determines that the need for the extra work was not reasonably evident, and the likelihood of needing the extra work was anomalous, the work will be paid for as provided under 109.04.

2. "ACCEPTED AS NOTED", which means unless otherwise noted on the drawings approved for construction, fabrication or manufacture, subject to the provision that the work shall be carried out in compliance with all comments or corrections indicated and in accordance with requirements of the contract. Final acceptance of work shall be contingent upon such compliance. If also marked "RESUBMIT", accepted as noted is valid, and a corrected submittal of the drawings is required; or

3. "NOT ACCEPTED", which means that deviations from the requirements of the contract exist in the submittal such that no work based on such drawings shall be constructed, fabricated, or manufactured. The Contractor shall revise the drawing in compliance with the comments and pursuant to all requirements of the contract and shall resubmit the working drawings for another review.

The Department's acceptance shall not relieve the Contractor of responsibility under the contract for the successful completion of the work Any work done or materials ordered prior to the approval of such working drawings shall be at the sole risk of the Contractor.

The cost of furnishing all working drawings shall be considered as included in the contract Lump Sum price for one or more of the contract items.

105.03 Conformity with Plans and Specifications. All work performed and all materials furnished shall be in reasonably close conformity with the lines, grades, cross sections, dimensions, and material requirements shown in the Conceptual Documents, on the plans or indicated in the specifications.

In the event the Director finds the materials or the finished product in which the materials are used not within reasonably close conformity with the plans and specifications but that reasonably acceptable work has been produced, he shall then make a determination if the work shall be accepted and remain in place. In this event, the Director will document the basis of acceptance by contract modification which will provide for an appropriate adjustment in the contract price for such work or materials as he deems necessary to conform to his determination based on engineering judgment.

In the event the Director finds the materials or the finished product in which the materials are used or the work performed are not in reasonably close conformity with the plans and specifications and have resulted in an inferior or unsatisfactory product, the work or materials shall be removed and replaced or otherwise corrected by and at the expense of the Contractor.

105.04 Coordination of the Conceptual Documents . The specifications, the supplemental specifications, the plans, the Scope Of Services, special provisions, and all supplementary documents are essential parts of the contract, and a requirement occurring in one is as binding as though occurring in all. They are intended to be complementary and to describe and provide for a complete work.

In case of discrepancy , the Addenda will govern over the Proposal, the Proposal will govern over the Scope Of Services, the Scope Of Services will govern over all specifications, the Department's specifications and manuals will govern over FHWA and AASHTO standards and specifications.

The Contractor shall take no advantage of any apparent error or omission in the Conceptual Documents. In the event the Contractor discovers such an error or omission, he shall immediately notify the Engineer. The Engineer will then make such corrections and interpretations as may be deemed necessary for fulfilling the intent of the Conceptual Documents. The Contractor shall cause the Consultant to make appropriate changes to the plans and drawings to implement that intent.

105.05 Cooperation by Contractor.

105.06 Cooperation with Utilities. As a part of the design, the Contractor shall work with utilities as outlined in 104.011.

As a part of the construction work, and based on utility relocation plans and estimates accepted by the Contractor and approved by the Department, the Contractor will notify all utility companies, all pipe line owners or other parties affected and arrange to have all necessary adjustments of the public or private utility fixtures, pipe lines and other appurtenances within or adjacent to the limits of construction, made as soon as practicable.

All utility facilities and all other utility appurtenances within the limits of the proposed construction which are to be relocated or adjusted will be moved by the owners at the direction of the Department at no cost to the Contractor, unless otherwise provided for in the proposal or noted on the project plans.

The design plans developed by the Contractor's Consultant will indicate various utility items, some of which will be relocated or adjusted by the utility owner, including a time frame or date by which the relocation work is expected to be completed. The Contractor shall give adequate notification to the utility owner who is adjusting their facilities during construction so as not to conflict with the Contractor's schedule of operations.

It is understood and agreed that the Contractor has considered in the bid all of the permanent and temporary utility facilities and utility appurtenances in their present positions and will coordinate and gain approval of all necessary relocations or adjustments, establish a schedule of adjustments that are mutually agreeable to the Contractor, the State and the utilities, and will take all necessary steps to assure that utility adjustments will not delay the project.

The Contractor shall cooperate fully with each utility company and shall make every effort to avoid delays.

In accordance with 153.64 ORC, at least 2 working days prior to commencing construction operations the Contractor shall notify the Engineer, the registered utility protection service and the owners of each underground utility facility who are not members of the registered utility protection service.

The owner of the underground utility facility shall, within 48 hours, excluding Saturdays, Sundays, and Legal Holidays, after notice is received, stake, mark or otherwise designate the location of the existing underground utility facilities in the construction area in such manner as to indicate their course together with the approximate depth at which they were installed. The marking or locating shall be coordinated to stay approximately 2 days ahead of the planned construction.

If, through the failure of the utility owners to relocate or adjust their facilities as provided for in the contract, the Contractor is delayed by causes which could not have been avoided by judicious design efforts, effective utility coordination and reasonable accommodation or by the judicious handling of forces, equipment and plant or by reasonable revision in the Contractor's schedule of operations, the Contractor may be granted a time extension [as the Engineer may find to be fair and reasonable.

The acceptability of such loss of time will be evaluated as follows:

(1) The Engineer shall be satisfied that the Contractor has made every effort to prosecute the design and construction work despite any delays encountered or revisions in the Contractor's scheduling of work.

(2) There will be no compensation for delay in prosecuting the work.

(3) If performance of the Contractor's work is delayed because the utility owners fail to relocate or adjust their facilities as previously agreed, the contract time will be adjusted in accordance with the provisions of 108.06.

Proof of insurance shall be submitted to the Department on the form prescribed by the Director. The Contractor shall be responsible for the deductible limit of the policy and all exclusions consistent with the risks he assumes under this Contract and as imposed by law.

In the event that the Contractor provides evidence of insurance in the form of certificates of insurance, valid for a period of time less than the period during which the Contractor is required by terms of this Contract to maintain insurance, said certificates shall be acceptable, but the Contractor shall be obligated to renew his insurance policies as necessary and to provide new certificates of insurance from time to time, so that the Department is continuously in possession of evidence that the Contractor's insurance is in accordance with the foregoing provisions.

In the event the Contractor fails or refuses to renew his insurance policies or the policies are canceled or terminated, or if aggregate limits have been impaired by claims so that the amount available is under the minimum aggregate required by $500,000.00 or more, or modified so that the insurance does not meet the requirements of this item, the Department may refuse to make payment of any further monies due under this Contract or refuse to make payment of monies due or coming due under other contracts between the Contractor and the Department. The Department in its sole discretion may use monies retained pursuant to this specification to renew or increase the Contractor's insurance as necessary for the periods and amounts referred to above. Alternatively, the Department may request that the Contractor's surety remedy any deficiencies with these insurance requirements or the State may default the Contractor for failure to comply with this specification. During any period when the required insurance is not in effect, the Engineer may suspend performance of the Contract. If the Contract is so suspended, no additional compensation or extension of time shall be due on account thereof.

Nothing in the Contract including but not limited to the plans, bid proposals, specifications and insurance requirements is intended to create in the public or any member thereof a third party beneficiary hereunder, nor is any term and condition or other provision of the Contract intended to establish a standard of care owned to the public or any member thereof.

107.19 Personal Liability of Public Officials. In carrying out any of the provisions of these specifications, or in exercising any power or authority granted to them by or within the scope of the contract, there shall be no liability upon the Director or his authorized representatives, either personally or as officials of the State, it being understood that in all such matters they act solely as agents and representatives of the State.

107.20 No Waiver of Legal Rights. Neither the inspection by the Engineer; nor by any of his duly authorized representatives, nor any order, measurements, or certificate by the Director, or said representatives, nor any order by the Director for the payments of money, nor any payment for, nor acceptance of any work by the Director, nor any extension of time, nor any possession taken by the State or its duly authorized representatives, shall operate as a waiver of any provision of this contract, or of any power herein reserved to the State, or any right to damages herein provided; nor shall any waiver or any breach of this contract be held to be a waiver of any other subsequent breach.

107.21 Environmental Protection. The Contractor shall comply with all Federal, State and local laws and regulations controlling pollution of the environment. Pollution of streams, lakes, ponds and reservoirs with fuels, oils, bitumens, chemicals or other harmful materials and pollution of the atmosphere from particulate and gaseous matter shall be avoided.

Fording of streams is permitted if the drainage area of the stream is less than 7.7 km2 (3 sq. mi.) and the Engineer approves the Contractor's plan to minimize siltation to the stream.

When work areas of pits are located in or adjacent to streams, such areas shall be separated from the main stream by a dike or barrier to keep sediment from entering the stream. Care shall be taken during the construction and removal of such barriers to minimize siltation of the stream.

Control of ground water and water in excavations shall be accomplished in a manner that will prevent the degradation of the water quality of any surface water. Wells and well points shall be installed with suitable screens and filters where necessary to prevent the continuous pumping of fines. The discharge of sediment-laden water from pumping shall be performed in a manner to prevent degradation of streams, lakes, ponds, or other areas of water impoundment. Such prevention may involve but is not limited to the use of ditch checks, sediment traps, sediment basins, sediment pits, or other control devices and methods necessary to prevent adverse effects to surface waters as provided in Chapter 3745-1-04 of the Ohio Administrative Code.

108.01 Subletting of Contract. The Contractor shall not sublet, sell, transfer, assign, or otherwise dispose of the contract or contracts or any portion thereof, or of his right, title, or interest therein, without written consent of the Director. A copy of any such subcontracts must be furnished to the Department. In case such consent is given, the Contractor will be permitted to sublet a portion thereof, but shall perform with his own organization, work amounting to not less than 50 percent of the total contract cost, except as set forth in paragraphs (3) and (4) hereof. The term "his own organization" shall be construed to include only workers employed and paid directly by the Contractor and equipment owned or rented by him with or without operators. Such term does not include employees or equipment of a subcontractor, assignee, or agent of the prime Contractor. An assignment of contract work is considered synonymous with a subcontract to perform work.

To determine whether the Contractor is in compliance with the requirement that he perform with his own organization contract work amounting to not less than 50 percent of the total contract price, the following criteria shall apply:

(1) The contract amount upon which the 50 percent requirement is computed shall include the cost of materials and manufactured products which are to be purchased or produced under the contract provisions.

(2) The percentage of subcontracted work, for purposes of this section, shall always be based on original contract prices rather than actual subcontract prices. Actual subcontract prices will be used for the purpose of calculating compliance with any Minority Business Enterprise (MBE) or Disadvantaged Business Enterprise (DBE) percentage subcontracting obligations. If only a part of a contract item is to be sublet, its proportional value shall be determined administratively on the same basis. This procedure should be followed even when the part not sublet consists only of procuring the materials. However, when a firm both sells materials to a Contractor and performs the work of incorporating the materials in the project, these two phases must be considered in combination and as constituting a single subcontract. If an affiliate of the firm either sells the materials or performs the work, the Department may refuse approval. An affiliate is one who has some common ownership or other close relation to said firm.

(3) Any items designated in the contract as "specialty items" may be performed by subcontract and the cost of any such specialty items so performed by subcontract may be deducted from the total cost before computing the amount of work required to be performed by the Contractor with his own organization. However, in no event shall the Contractor perform less than 35 percent of the total contract cost. No subcontract, or transfer of contract, shall release the Contractor of his liability under the contract and bonds, unless release is granted by the Director.

(4) When bidding on a particular project has been restricted to Disadvantaged Business Enterprises or Minority Business Enterprises, the Disadvantaged Business Enterprise or Minority Business Enterprise contractor shall perform with his/her own organization, work amounting to not less than 51 percent of the remainder obtained by subtracting from the total original contract amount the sum of any item designated in the contract as "specialty items" if these items are sublet, as required by Section 5501:5-1-05 of the Ohio Administrative Code.

108.02 Pre-design and Pre-construction Conference :

The DBT shall meet with the Project Engineer and the Project Manager for a pre-design conference prior to commencing design work.

The Contractor shall furnish a Progress Schedule, as required by the SOS, and a list of all sub-consultants and other firms involved in the design process .

The DBT shall meet with the Project Engineer and the Project Manager for a pre-construction conference prior to commencing construction work.

The Contractor shall furnish a list of the Contractor's proposed subcontractors and major material suppliers not included in the list submitted prior to the signing of the contract.

If the Contractor fails to provide the required submissions, at the pre-design or pre-construction conferences, the Engineer may order the conferences suspended until such time as they are furnished and work shall not begin until the conference has been reconvened and concluded or the Engineer has given specific written permission to proceed.

108.03 Prosecution and Progress. The Contractor shall start the work in accordance with the approved Progress Schedule as required in the Scope Of Services. The Contractor shall notify the Engineer at least 24 hours before beginning work.

The work shall be diligently and continuously carried on to completion and the Contractor agrees to provide at all times an adequate force of labor and sufficient materials and equipment to insure the completion of the contract within the time allowed. The progress of the work shall be at a rate sufficient to complete the contract in an acceptable manner within the time allowed.

Should design or construction progress differ significantly from the Progress Schedule presented at the preconstruction conference, the Engineer may request that the Contractor submit a revised progress schedule and anticipated completion dates of the major phases of work remaining and the anticipated completion date of the work. The Contractor shall submit the revised progress schedule within ten (10) calendar days after the request. Failure to provide an accurate, appropriate Progress Schedule may be grounds for the suspension of the work.

At a mutually convenient location and time as determined by the Engineer, the contractor shall meet with the Engineer to discuss construction activities. Minutes of these meetings will be kept by the Engineer and a copy given to the Contractor.

108.031 Monthly Progress Report. Progress meetings will be held every four (4) weeks at the project office, or other location designated by the Project Engineer, and attended by ODOT and the Contractor decision-making personnel. The purpose of these meetings will be to discuss adherence to the Progress Schedule and its periodic updates, critical operations and potential problems. The Contractor will confirm the number and duration of work shifts, number of work crews, and specific portions of the work to be performed during the following weeks. These meetings can only be waived by the Project Engineer.

108.032 Termination of Contract. The Director may terminate the contract for the convenience of the Department at any time. The Contractor will be compensated for design work under the provisions of the "Specifications for Consulting Services" and for construction work under 109.04 for added expense not including anticipated profits for termination of the contract for the convenience of the Department. This section is subject to the provisions of 5525.14, ORC.

108.04 Limitation of Operations. The Contractor shall conduct the work at all times in such a manner and in such sequence as will assure the least interference with traffic. He shall have due regard to the location of detours and to the provisions for handling traffic. He shall not open up work to the prejudice or detriment of work already started. The Engineer may require the Contractor to finish a section on which work is in progress before work is started on any additional sections if the opening of such section is essential to public convenience, or if necessary for the protection of portions of the existing and/or new facility from damages by action of the elements or from any other causes.

The Contractor shall take all necessary precautions and actions to prevent pollution of streams, lakes and reservoirs with fuels, oils, bitumens, calcium chloride or other harmful materials and to prevent pollution of the atmosphere from particulate and gaseous matter.

Proposed erosion control items provided in the contract, exclusive of seeding, shall be constructed concurrently with or immediately following earthwork or structure work of which they are a part. Seeding, mulching and protecting of major exposed slopes shall not be delayed until such time as they can be performed on a project wide basis. This work shall be performed in stages and shall be accomplished as soon as finished grade for seeding can be established in any significant portion of the project. The Contractor shall finish and seed, consistent with the general requirements of the specifications, significant portions of the project where, the grading has reached a stage that finishing thereof is incidental. Temporary control of water pollution, soil erosion, sedimentation and additional limitations of areas of erodible earth material exposed by clearing, grubbing and earthwork operations shall be in accordance with Supplemental Specification 877 and section 877.05 as modified in this proposal. The Contractor shall at all times conduct his operations in accordance with approved schedule. Whenever any excavation, embankment or earth cofferdam work is to be performed in or immediately adjacent to a live stream, the Contractor shall submit details of such operations so that the Director may forward them to the Ohio Department of Natural Resources, Division of Wildlife.

108.05 Character of Workers, Methods and Equipment. The Contractor shall at all times employ sufficient labor and equipment for prosecuting the several classes of work to full completion in the manner and time required by these specifications.

All workers shall have sufficient skill and experience to perform properly the work assigned to them. Workers engaged in special work or skilled work shall have sufficient experience in such work and in the operation of the equipment required to perform all work properly and satisfactorily.

Any person employed by the Contractor or by any subcontractor who, in the opinion of the Engineer, does not perform his work in a proper and skillful manner or is intemperate or disorderly shall, at the written request of the Engineer, be removed forthwith by the Contractor or subcontractor employing such person, and shall not be employed again in any portion of the work without the approval of the Engineer.

Should the Contractor fail to remove such person or persons as required above, or fail to furnish suitable and sufficient personnel for the proper prosecution of the work, the Engineer may withhold all estimates, which are or may become due, or may suspend the work by written notice until the Contractor complies with such orders.

All equipment which is proposed to be used on the work shall be of sufficient size and in such mechanical condition as to meet requirements of the work and to produce a satisfactory quality of work. Equipment used on any portion of the project shall be such that no injury to the roadway, adjacent property, or other highways will result from its use.

When the methods and equipment to be used by the Contractor in accomplishing the construction are not prescribed in the contract, the Contractor is free to use any methods or equipment that he demonstrates to the satisfaction of the Engineer will accomplish the contract work in conformity with the requirements of the contract.

When the contract specifies that the construction be performed by the use of certain methods and equipment, such methods and equipment shall be used unless others are authorized by the Engineer. If the Contractor desires to use a method or type of equipment other than those specified in the contract, he may request authority from the Engineer to do so. The request shall be in writing and shall include a full description of the methods and equipment proposed to be used and an explanation of the reasons for desiring to make the change. If approval is given, it will be on the condition that the Contractor will be fully responsible for producing construction work in conformity with contract requirements. If, after trial use of the substituted methods or equipment, the Engineer determines that the work produced does not meet contract requirements, the Contractor shall discontinue the use of the substitute method or equipment and shall complete the remaining construction with the specified methods and equipment. The Contractor shall remove the deficient work and replace it with work of specified quality, or take such other corrective action as directed. No change will be made in basis of payment for the construction items involved nor in contract time as a result of authorizing a change in methods or equipment under these provisions.

108.06 Date for Completion. The Contractor shall have completed the work on or before the calendar date specified in the proposal, or on or before a later date determined as specified herein, otherwise the Director shall proceed as provided in 108.07 or 108.08.

If the contract is revised in any material respect and it is determined that said revision will cause delay in the completion of the work, the Director will postpone the completion date by the number of calendar days he determines.

If the Contractor finds it impossible for reasons beyond his control to complete the work by the date as specified or as extended in accordance with the provisions of this subsection, the Contractor may make a written request to the Engineer for an extension of time setting forth therein the reasons which the Contractor believes will justify the granting of the request.

The Contractor's pleas that insufficient time was specified is not a valid reason for extension of time. If the Director finds that the work was delayed because of conditions beyond the control and without the fault of the Contractor, he may extend the time for completion in such amount as the conditions justify.

Requests for extensions of time, other than for weather or seasonal conditions, shall be submitted in writing to the Engineer within 30 days following the termination of the delay and prior to the expiration of the extended contract completion date existing before the request.

Requests for extensions of time due to weather or seasonal conditions shall be submitted in writing to the Engineer at the end of each month. The contract completion date, or the extended contract completion date, shall be postponed by one work day for each lost work day caused by weather. The time between December 1 and April 30 is considered winter months and no extension will be granted for this time. A work day will be counted as lost if the Contractor's efficiency is reduced more than 50 percent on the critical item under construction at that time. Weekends and holidays will not be counted as lost work days unless the Contractor normally works those days. The extended time for completion shall then be in full force and effect the same as though it were the original time for completion.

If the Director should suspend the work in whole or in part as provided in 108.031, the date for completion shall be postponed by the number of days that the suspension directly or indirectly delays the completion of the work.

108.07 Failure to Complete on Time. If the Contractor fails to complete the work within the time or times allowed by the contract, the Director, if satisfied that the Contractor is carrying the work forward with reasonable progress, and the Director deems it to be in the best interest of the public, may allow the Contractor to continue in control of the work. It shall be necessary for the Contractor to make written application to the Director in order to warrant such continuance. Payments to the Contractor for work performed and materials furnished will be made.

When the work is not completed within the time or times allowed by the contract and the Contractor is permitted to remain in control, the work shall be prosecuted at as many different places, at such times and with such forces as the Director may request. The Contractor may be required to provide a written plan for the completion of the work.

For each calendar day that any work shall remain uncompleted after the contract completion date or dates, the sum specified herein will be deducted from any money due the Contractor, not as a penalty but as liquidated damages; provided, however, that due account shall be taken of any adjustment of the completion date or dates granted under the provisions of 108.06. In the event one or more interim completion dates are specified without specific separate liquidated damages, the amount set forth in the Schedule herein will separately apply to each interim date. In the event a period of liquidated damages for an interim completion date overlaps a subsequent completion date, the higher rate of liquidated damages will apply for the duration of the overlap.

Permitting the Contractor to continue and finish the work or any part of it after the date or dates fixed for its completion, or after the date or dates to which completion may have been extended, will in no way operate as a waiver on the part of the Department of any of its rights under the contract.

The Director may waive such portions of the liquidated damage as may accrue after the work is in condition for safe and convenient use by the traveling public.

108.08 Unsatisfactory Progress and Termination of Contract. If the Contractor has not commenced his work within a reasonable time, or does not carry the same forward with reasonable progress, or is improperly performing his work, or has abandoned, or fails, or refuses, to complete the work, the Director shall make a finding to that effect and so notify the Contractor in writing. Upon receipt of this notification by the Contractor the right of the Contractor to control and supervise the work shall immediately cease. In such a case the Director will proceed in accordance with the provisions of 5525.17, ORC.

108.09 Payroll Records. Payroll records kept in accordance with 4115.07, ORC, shall be open to inspection of authorized representatives of the Director. Upon completion of the work and prior to the payment of the final estimate the Contractor shall submit an affidavit stating that wages have been paid in conformance with the minimum rates set forth in the contract for construction of the project.

108.10 Post Construction Meeting. Approximately 10 days after the final inspection either party to the contract may request a post construction meeting. If one party makes such a request, a post construction meeting is then mandatory. The Engineer shall conduct the meeting to critique the contract documents (i.e., plans, proposal). The meeting will be at a time and place as determined by the Engineer.

The performance of both parties shall also be discussed including portions of the project sublet. The Engineer shall contact the Design agency or consultant and the local Government agency to request a representative attend this meeting.

Minutes shall be taken by the Engineer at this meeting. Copies of these minutes shall be distributed to the following: Contractor; Agency that prepared the plans; Offices of Roadway Engineering, Structural Engineering, and/or Traffic Engineering, as appropriate; Office of Highway Management; District Highway Management Administrator; District Production Administrator; Local Government Agency, if applicable.

For projects which will take two or more full construction seasons to complete, an additional construction meeting may be held at the request of either party at approximately the mid-point of the Contract.

The cost of attending this meeting shall be incidental to the Contract.


109.01 Measurement of Quantities. The pricing and payment format of this contract is intended to be Lump Sum. The Lump Sum item of payment shall mean complete payment for the work described in that item . To the greatest extend possible, the Contractor will be compensated for the percentage of the applicable fixed Lump Sum price. The percentage shall be that portion of work completed as compared to the total amount of work contracted.

The term metric ton will mean 1000 kilograms. The term "ton" will mean the short ton consisting of 2000 pounds avoirdupois. All materials which are measured or proportioned by weight shall be weighed on accurate, approved scales by competent, qualified personnel at locations approved by the Engineer. If material is shipped by rail, the car weight may be accepted provided that only the actual weight of material is paid for. However, car weights will not be acceptable for materials to be passed through mixing plants. Trucks used to haul material being paid for by weight shall be weighed empty at least once daily at such times as the Engineer directs only if the weight of the truck is used in determining the ticket weight. Each truck shall bear a plainly legible identification mark.

All materials which are specified for measurement by the cubic yard (cubic meter) "loose measurement" or "measured in the vehicle" shall be hauled in approved vehicles and measured therein at the point of delivery on the road. Approved vehicles for this purpose may be of any type or size satisfactory to the Engineer, provided that the body is of such type that the actual contents may be readily and accurately determined. Unless all approved vehicles on a job are of uniform capacity, each approved vehicle must bear a plainly legible identification mark indicating the specific approved capacity. The Inspector may reject all loads not hauled in such approved vehicles.

For work on a tonnage basis, the Contractor shall file with the Engineer receipted freight bills where railroad shipments are made, and certified weigh-bills when materials are received by any other method, showing the actual tonnage used. For work on a volume basis, the Contractor shall furnish itemized evidence of the volume used. Freight bills, weigh-bills, and volume certificates shall be furnished to the Inspector as requested.

The following materials will be paid for by the gallon (liter) at the following temperatures:

At 60F (16C) Creosote for Priming Coat, Creosote Oil and Creosote Solutions for Timber Preservatives, Asphalt Primer for Water- proofing, and Liquefier.

At 100F (38C) RC, MC, Asphalt Emulsions, RT-1, 2, 3, 4, 5, 6 and CBAE, Primer 20 and 100.

At 200F (93C) RT-7, 8, 9, 11 and 12.

At 300F (149C) Asphalt Cement and Oil Asphalt Filler, Grade A.

Tank car outage of bituminous material shall be measured at destination before any material has been removed from the tank car, in accordance with standard operating procedure PH-C-304.

For shipments of bituminous materials, the net weight shall be converted to gallons (liters) at the specified pay temperature in accordance with standard operating procedure PH-C-304.

Companies or contractors furnishing bituminous material in calibrated distributors or tank trucks shall file with the Director a certified list of the capacities of this equipment. The gallons (liters) at the measured temperature shall be converted to gallons (liters) at the specified pay temperature in accordance with standard operating procedure PH-C-304.

Timber will be measured by the thousand feet board measure, MFBM (cubic meter) actually incorporated in the structure. Measurement will be based on nominal widths and thicknesses and the extreme length of each piece.

The term "lump sum" when used as an item of payment will mean complete payment for the work described in the item.

When a complete structure or structural unit (in effect, "lump sum" work) is specified as the unit of measurement, the unit will be construed to include all necessary fittings and accessories.

When standard manufactured items are specified such as fence, wire, plates, rolled shapes, pipe conduit, etc., and these items are identified by size, unit weight, section dimensions etc., such identification will be considered to be nominal weights or dimensions.

109.011 Metric Conversion : Any metric standard drawings used for this project shall be converted to English units using the SI (Metric) to English Conversion Factors provided in this section. The appendix of ASTM E 380 shall be utilized for any additional conversion factors required.

109.02 Scope of Payment. The Contractor shall receive and accept compensation provided for in the contract as full payment for furnishing all materials and for performing all work under the contract in a complete and acceptable manner and for all risk, loss, damage, or expense of whatever character arising out of the nature of the work or the prosecution thereof, except as otherwise provided in 104.02, 105.17 and 107.16.

If the "Basis of Payment" clause in the specifications relating to any Lump Sum or unit price in the bid schedule requires that the said Lump Sum or unit price cover and be considered compensation for certain work or material essential to the item, this same work or material will not also be measured or paid for under any other pay item which may appear elsewhere in the specifications.

109.04 Extra and Force Account Work. Extra work performed in accordance with the requirements and provisions of 104.03 will be paid for at the unit prices or lump sum stipulated in the order authorizing the work, or the Department may require the Contractor to do such work on a force account basis to be compensated in the following manner:

(a) Labor. For all labor and for all foremen in direct charge of the specific operations, the Contractor shall receive the rate of wage and fringe benefits currently in effect at the time the work is performed for each and every hour that said labor and foremen are actually engaged in such work, to which may be added an amount equal to 38 percent of the sum thereof. The term fringe benefits shall be defined as the actual costs paid to, or in behalf of, workers by reason of health and welfare benefits, pension fund benefits or other benefits, when such amounts are required by collective bargaining agreement or other employment contract generally applicable to the classes of labor employed on the work. In addition to the above, the Contractor shall receive the actual cost of Social Security Tax, Workmen's Compensation and State and Federal Unemployment Insurance. In lieu of itemizing these four items, 15 percent of the base wages may be added.

The wages of any foreman or timekeeper, who is employed partly on force account work and partly in other work, shall be prorated between the two classes of work according to the number of people employed on each class of work as shown by the payrolls.

The estimated rate of wage and labor cost is to be agreed upon in writing before beginning work.

The Contractor shall receive the actual costs paid for subsistence and travel allowances when such payments are required by collective bargaining agreement or other employment contract generally applicable to the classes of labor employed on the work. No percentage may be added to these costs.

(b) Materials. For materials accepted by the Engineer and used, the Contractor shall receive the actual cost of such materials delivered on the work, including transportation charges paid (exclusive of machinery rentals as hereinafter set forth), to which cost 15 percent may be added.

(c) Equipment. Equipment which the Engineer considers necessary for the performance of work will be eligible for payment at the established rates only during the hours that it is operated except as otherwise allowed elsewhere in these specifications. Equipment hours will be recorded to the nearest one-half hour. The equipment rental rates established herein include allowance for overhead and profit except where otherwise specified. For the use of equipment approved by the Engineer, the Contractor will be paid the rental rates, as modified herein, set forth in the Rental Rate Blue Book for Construction Equipment which is published by the Equipment Guide-Book Company.

(1) Rental Rates (Without Operators). The rental rate for each item of equipment will be the sum of the base machine rate, attachment rate and operating rates(s).

The base rate for the machine and attachments represent the major cost of equipment ownership, such as depreciation, interest, taxes, insurance, storage and major repairs. The hourly operating rate represents the major costs of equipment operation, such as fuel and oil lubrication, field repairs, tires, expendable parts and supplies.

For all equipment utilized on force account work, the hourly rate for each piece of equipment and attachments will be paid at the Blue Book monthly rate for the make and model multiplied by the appropriate rate adjustment factor, divided by 176, plus the hourly operating costs. However, compensation for equipment normally used on a 24-hour day basis will not exceed the monthly rate plus adjustments and operating costs.

The rate adjustment factor assigned to any attachment will be the yearly factor as determined for the base equipment.

When multiple attachments are included with the rental equipment, only the attachment having the higher rental rate will be eligible for payment, provided the attachment has been approved by the Engineer as being necessary to the force account work.

Rental charges will not be allowed for small tools that show a daily rate less than 5 dollars or for unlisted equipment that has a value of less than 400 dollars.

The above provisions apply to approved equipment of modern design and in good working condition. The equipment shall be handled and used to provide normal output or production. Equipment that is not in good working condition or is not of proper size for efficient performance of the work may be rejected by the Engineer. Equipment ordered for force account work will be paid for until such time as the Engineer directs that the use of such equipment be discontinued or until completion of the work.

For any equipment not listed in the Blue Book, rental rates shall be agreed to in writing prior to the use of such equipment on force account work or paid for by invoices in the case of outside rented equipment.

(2) Stand-By or Idle Equipment Time. Equipment that is in operational condition and is standing by with the Engineer's approval for participation in force account work will be paid for at 50 percent of the appropriate hourly rate as determined by the provisions set forth herein less operating costs. Payment for such "stand-by" will be limited to not more than 8 hours in a 24 hour day or 40 hours in a normal work week.

No compensation will be allowed for equipment that is inoperable due to breakdown.

No payment will be allowed for equipment that is not operating because the work has been suspended in accordance with the specifications unless the suspension is for the convenience of the State. No payment will be allowed for equipment that is not operating because the work has been suspended by the Contractor for the Contractor's own reasons.

The hourly rate of compensation for idle equipment will be the monthly rate times a factor of 0.50 divided by 176 hours per month, regardless of the duration of the delay or stand-by

The time for which such compensation will be paid will be the actual normal working time during which such delay condition exists, but will in no case exceed 8 hours in any one day.

The days for which compensation will be paid will be the number of working days charged during the existence of such delay. No compensation will be made for days that are considered lost due to weather as determined by the Engineer.

Compensation will only be made for equipment physically located at the work site that would be used to prosecute the delayed work during the existence of such delay

(3) Outside Rented Equipment. In cases where a piece of equipment to be used is rented or leased by the Contractor from a third party exclusively for force account work, the actual invoiced amount will be paid subject to the limits stated in the following paragraph and when such rates are reasonably in line with established rental rates for the equipment in question and approved by the Engineer. A 15 percent markup will be allowed for overhead and profit for all rented equipment paid for by invoices. To this amount, the hourly operating cost will be added.

In no case will equipment be considered for rental which exceeds the hourly rate for the first 8 hours and the daily rate divided by 8 for all additional hours as compared with similar equipment listed in the Blue Book unless approved in advance by the Engineer.

(4) Moving of Equipment. Rental time will also be allowed for the time required to move needed equipment to location of the force account work and to return it to its original location. Loading and transportation costs will be allowed in lieu of moving times when equipment is moved by means other than its own power. Moving time back to the original location or loading and transportation costs will not be allowed if the equipment is used at the site of the force account work on contract items or related work.

For use of equipment moved on the work exclusively for force account work, the actual cost of transferring the equipment to the site of the work and returning it to the original location will be allowed as specified herein as an additional item of expense.

The original location of the equipment to be hauled to the site of the work shall be agreed to by the Engineer in advance.

When moving equipment by common carrier, the allowance will be the invoiced amount paid for the freight plus 15 percent If the Contractor's forces haul the equipment, rental will be allowed for the hauling unit plus the driver's wages and the cost of loading and unloading the equipment

The maximum rental period for the day that the equipment is moved on the work and the day that use of the equipment is discontinued shall be the actual time that the equipment is in operation on force account work.

(d) Foreman's Transportation, A flat hourly rate, which includes fuel and lubricants, profit and overhead, and any other costs will be allowed.

(e) Subcontract Work. For work performed by an approved Subcontractor, the prime Contractor will be allowed an amount to cover administrative costs equal to 5 percent of the compensation provided in (a), (b), (c) and (d), but not to exceed $10,000. No additional mark-up is allowed for work of a sub-subcontractor employed by a sub-contractor.

(f) Compensation. On this project the requirements of 109.04 (f) of the Construction and Material Specifications are modified as follows to include general liability insurance premiums in mark ups on extra work: The compensation to the Contractor as provided in (a), (b), (c), (d), and (e) of 109.04 shall constitute payment in full for extra work on a force account basis. The mark ups specified in (a), (b), (c), and (e) of 109.04 shall compensate for the following:

1. Administration
2. Superintendence
3. Project overhead
4. Home Office Overhead
5. Use of tools and equipment for which no rental is allowed
6. Profit
7. Taxes other than sales tax
8. Premiums on insurance including additional premiums for Commercial General Liability Insurance required under 107.14 and any additional coverage carried by the Contractor or subcontractor, excluding pollution and railroad liability insurance
9. Any other expense incidental to perform the work.

Sales tax will not be allowed on any item for which tax exemption may be obtained.

Premiums for pollution and railroad liability insurance shall be compensated by a separate agreement for the full cost of the premium without any mark up.

Compensation for the foreman's transportation provided in (d) shall include any mobile communication units used by the Contractor or subcontractor.

The above described force account provisions will also apply to work performed at agreed unit prices and agreed lump sums when the agreed prices are based on analyses of cost of labor, material, and equipment.

(g) Statements, Final payment will not be made for work performed on a force account basis until the Contractor has furnished the Engineer with itemized statements of the cost of such force account work detailed as follows:

(1) Name, classification, date, daily hours, total hours, rate and extension for each laborer and foreman.

(2) Designation, dates, daily hours, total hours, rental rate and extension for each unit of machinery and equipment

(3) Quantities of materials, prices and extensions

(4) Transportation of materials

The Contractor's representative and the Engineer shall compare records daily of the cost of work done as ordered on a force account basis. The Contractor shall certify that these records are correct and both the Engineer and the Contractor shall sign off.

Statements shall be accompanied and supported by proper invoices for all materials used, transportation charges and rented equipment performing work on force account operations. If materials used on the force account work are not specifically purchased for such work but are produced by the Contractor or taken from the Contractor's stock then, in lieu of the invoices, the Contractor shall furnish an affidavit certifying that such materials were produced by him or taken from his stock, that the quantity claimed was actually used and that the price and transportation claimed represent the actual costs to the Contractor. Statements shall be filed not later than the 20th day of the month following that in which the work was actually performed

The above described force account provisions will also apply to work performed at agreed unit prices and agreed lump sums when the agreed prices are based on analyses of cost of labor, material and equipment.

109.06 Partial Payments. If satisfactory progress is being made, the Contractor will receive monthly payments of the amount of value of work and materials in place. The monthly payment is approximate only, and all partial estimates and payments shall be subject to correction in the final estimate and payment.

The Contractor may submit monthly invoices for payment based upon lump sums bid. For each item, the Contractor shall estimate the current percentage completion of that item of work. The Project Engineer shall review each proposed current percentage completion and revise the percentage when appropriate. The agreed current percentage of completion multiplied by the lump sum price bid shall define the gross amount due the contractor for that item of work.

No estimate will be paid until the Contractor has presented to the Director of Transportation certificates from the Industrial Commission of Ohio that the Contractor has complied with each and every condition of 5525.18, ORC.

Estimates may be allowed twice each month if in the judgment of the Engineer the amount of work performed is sufficient to so warrant.

Should any defective work or material or acceptable work that has been damaged by the Contractor's operations be discovered previous to the final acceptance or should a reasonable doubt arise previous to the final acceptance as to the integrity of any part of the completed work, the estimate and payment for such defective or questioned work shall not be allowed until the defect has been remedied and cause for doubt removed.

109.07 Payment for Material on Hand. Partial payments may be made to the extent of the delivered cost of approved materials to be incorporated in the work, when delivered on the project or stored in acceptable storage places in the vicinity of the project.

Partial payments may be made to the extent of the cost of approved materials to be incorporated in the work when assigned to the Contractor, if the Engineer determines that it is not practical to deliver the material to the project site. This provision shall be applicable only to bulky materials that are durable in nature and represent a significant portion of the project cost, such as aggregates, steel and precast concrete. Small warehouse items may not be included.

No partial payment will be made on living or perishable plant materials until planted.

109.071 AcceptanceTraffic Detoured.

(A) Acceptance and Opening to TrafficPart of Project. When a portion of a highway or structure covered by contract is substantially completed, a partial acceptance may be made by the Director and that portion opened to traffic when such opening will benefit the public interest. When all items on a portion of the highway are completed, upon written authorization by the Director, the Contractor may cease to maintain barriers, lights and traffic control devices covering the accepted portion.

The Contractor shall not be required to maintain portions of the highway or structures which have been completed and accepted, but he is required to repair any damage caused by his operations, defective work, or non-compliance with the plans, specifications and contract until the final estimate has been approved by the Director.

(B) Acceptance and Opening to Traffic when Progress is Unsatisfactory or Work is Suspended. When a portion of a highway or a structure is completed and the progress schedule of work has not been met or the Contractor suspends work for over 14 days during the normal construction season the Director on written notice to the Contractor may order the road or structure to be opened for travel and the Contractor shall place the highway, bridge or culvert or portions thereof in such condition for travel as the Director may order and shall remove all barriers and obstructions at no cost to the State of Ohio.

(C) Acceptance and Opening to Traffic when Ordered by the Director. Upon written notice from the Director directing that the highway, bridge, or culvert, or any part thereof be opened for travel, the Contractor shall put the highway, bridge or culvert or such portions thereof as the Director may direct in such condition for travel as the Director may direct, and shall remove all barriers and obstructions. (5517.03 ORC.) Acceptance of the work in whole or in part is not involved in this case, but the Contractor will not be held responsible for damage by such traffic to completed or partially completed portions of the work. Additional costs to the Contractor by such action shall be reimbursed in an agreed manner.

109.072 Acceptance Traffic Maintained. When traffic is maintained the Director, at the request of the Contractor, may accept a portion of a project when such acceptance will serve the public interest.

A portion of the project shall be defined as a section of highway or structure on which all items of work have been completed, or, a substantial part or feature of the work that is completed and that is not dependent for its stability and integrity upon other uncompleted items of work and that can be received for public usage prior to completion of all work in the contract. Acceptance of a portion of the project will relieve the Contractor of responsibility for maintenance and damage due to traffic and all retained percentages shall be released and paid to the Contractor for those portions of the project named in the acceptance notice. The Contractor shall not be required to maintain portions of the highway or structures which have been completed and accepted, but he is required to repair any damage caused by his operations, defective work, or noncompliance with the plans specifications and contract until the final estimate has been approved by the Director.

109.073 Final Inspection. When the work has been completed to the satisfaction of the Engineer he shall so notify the Director who will, in general within 10 days unless otherwise provided, make the final inspection.

109.08 Acceptance and Final Payment. Before the final estimate is allowed the Director may require the Contractor to submit an affidavit from each and every subcontractor showing that all claims and obligations arising in connection with the performance of his portion of the contract have been satisfactorily settled. The improvement shall be inspected by the Director, and if he finds the work is completed according to the contract, there shall be issued certificates of the amount of work done and the Contractor shall receive the balance due on the contract. It is expressly stipulated that the State of Ohio shall make final acceptance and payment promptly after the contract has been fully completed and final inspection made. No payment shall be made for any unauthorized work.

109.09 Termination of Contractor's Responsibility. This contract will be considered complete when all work has been completed, and the final inspection made, the work accepted and the final estimate approved, in writing, by the Director. The Contractor will then be released from further obligations except as set forth in his bond. The date the final estimate is approved, in writing, by the Director shall constitute the acceptance contemplated by Section 5525.16 ORC.
