SCOPE OF SERVICES

 

Manual

 

 

It’s what you learn after you know it all that counts  John Wooden

 

Introduction                                                                                                                                                   

 

This manual has been designed to help the district personnel in preparing the Scope Of Services.


 

Up front project definition will help minimize change orders. So please follow these guidelines when writing the Scope Of Services:

           


                     You must conduct a field review prior to start writing the scope. You have to know what is out there and what you want so you are be able to define it.


 

                     Items such as fatigue analysis and corrosion protection system need to be evaluated up-front by the district, so that the required repairs can be defined in the scope .

                     Avoid using phrases such as : as directed by the engineer...; if recommended by the department, typical work comments, the district preference is .....these are not contract rules and will invite negotiation and the lessening of quality during construction.

                     Avoid using words such as : Rehabilitation of…; Reuse existing….; Repair …. If needed then set parameters so that all bids are even and work can be enforced during construction.

                     When ODOT design and specification requirements allow more than one option, but the district has a preference, you must specify the preferred option up-front in the scope.

                     Avoid procedural directions in the construction process unless absolutely necessary.

                     Remember that Design-Build Team is only responsible for what is called for in the Scope Of Services and the remainder of the Conceptual Documents. As a general rule, district preferences, plan notes and special provisions must be specifically listed or called for in the bid documents so that all contractors can bid on them and the district can enforce them during construction.                                                         

 

With the continuous support of the Division Of  Highway Operations,  I will help the district review the Scope Of Services and I will be available to answer any questions. On large projects I recommend that the district conduct a post scope meeting before sending the final package to central office.

 

Our goal is to produce a Scope Of  Services that can be used as a model nation wide.

 

Thank you,

 

Daniel Groh, P.E.

Design Build Coordinator

[The approximate number of affected ownerships shown hereon is estimated.  The actual number of affected ownerships may vary depending on the work being performed, the final determination of property lines or any property splits.  The total number of parcels (permanent and temporary) may vary from the number of affected ownerships.]

 

The Right of Way Cost Estimate will be provided by ODOT.

 

42 Year Title Searches and Title Reports will be performed by an ODOT pre-approved Title Agent as contracted by the DBT prior to the Preliminary Plan Review Submission.  Continuation of Title Reports will be performed by an ODOT pre-approved Title Agent as contracted by the DBT prior to the Submission of R/W Plans (1507). 

 

Title Report: The DBT will be responsible for submitting a Title Report and Title Chain for any acquisition in accordance with the Real Estate Policies and Procedures Manual which will identify ownership, liens, or other interests in the property to be acquired.  A report shall be prepared for each property.  Said Title Report will cover a period of ownership of not less than 42 years.  Title Reports will be submitted to the District Real Estate Administrator no later than the Preliminary Plan Review Submission. 

 


Continuation of Title Report : The DBT will be responsible for submitting a Continuation of Title Report and if applicable, a Title Chain, for any acquisition in accordance with the Real Estate Policies and Procedures Manual which will identify ownership, liens, or other interests in the property to be acquired.  A report shall be prepared for each property.  Said Continuation of Title Report will cover the period of time from the completion of the original title report to no more than fifteen (15) working days immediately prior to the Submission of R/W Plans (1507).  Continuation of Title Reports will be submitted to the District Real Estate Administrator no later than the    Submission of R/W Plans (1507).

 

 

Existing and proposed right of way lines will be located by the DBT based on requirements specified in Chapter 4733-37 of the Ohio Revised Administrative Code (Board Rules) governed by regulations outlined in Chapter 4733, Ohio Revised Code (Regulation Laws) and in accordance with any special requirements of the County(s) in which the project is located.  It is the responsibility of the DBT to research right of way information from all available sources including but not limited to ODOT records, County road records, Commissioners’ Journals and records of other County offices to the extent necessary to provide an accurate basis for the establishment of the right of way.

 

The DBT will establish an accurate centerline of right of way as legal descriptions are tied to said centerline.

 

All topographic features within 100 feet of either side of the proposed right of way will be accurately located and identified.

 

Underground facilities, to include, but not limited to, storage tanks, septic tanks/systems, leach beds, utilities, including service lines (in accordance with Section 153.64 Ohio Revised Code), drain pipes and exposed field tiles will be located and identified as to the size and type.

 

All existing and set monumentation (centerline, R/W, subdivision, volume and page, and civil boundaries) within the project work limits will be located, identified, shown and labeled on the right of way plan.  All control points (section corners, centerline control) outside the project work

 

limits, but needed for alignment and legal descriptions, will be located, etc. (as above).  Centerline and control points will be tied to State Plane Coordinates NAD83(95).  The Project Adjustment Factor necessary to convert the State Plane Coordinates will be reported and shown on the centerline plat.

 

The DBT will set monuments on all property line intersections, breaks and corners on the proposed permanent right of way lines.  Monuments will be 3/4 in. diameter steel rod or bar, 30 in. long, topped with a minimum 1 ½ in. diameter aluminum cap stamped ODOT R/W and bearing the surveyor’s name, Ohio registration number and/or company name.  The monument legend in the plan and the legal descriptions will recite these monuments and refer to the actual wording on the cap.  Hubs are to be set flush with the ground on the corners and breaks of all channel, slope, sewer and temporary easement parcels to be acquired.  The District Real Estate Administrator will notify the DBT when these monuments/hubs are to be set, by letter, when the

right of way acquisition is complete.  The DBT will certify, by letter, to the District that the work was completed.  

 

The DBT will stake and flag the proposed right of way in the field prior to the start of construction and will maintain said stakes through the duration of the project.  Staking and flagging of the proposed right of way to facilitate appraisal and negotiation will be done by the DBT upon request by ODOT.

 

The DBT will identify and show all right of way encroachments on the right of way plans at the Conceptual Review Submission.  ODOT’s District Office will be responsible for clearing all encroachments on Federal-aid projects in accordance with standard encroachment removal procedures.

 

On certain projects, e.g., structure replacement, with minimal right of way requirements, an alternate right of way plan format may be utilized based on approval of the District Production Administrator.

 

The type of title to right of way (standard highway easement or warranty deed) designated for the roadway portion of a project will depend on the nature of the project itself.  Once project development has progressed to the point where a determination of type of title and amount of right of way can be made, the DBT shall promptly provide pertinent information developed to date, as deemed necessary by the District Real Estate Administrator, for the latter to make an informed decision in this matter.

 

The DBT will utilize property ownership data for right of way plan development based on a search of County records conducted no more than six (6) months prior to the Conceptual Review Submission.  The DBT will submit copies of each property owner’s record deed transferring title to that owner to the District Real Estate Office with the Conceptual Review Submission.  In cases where partial title interest is conveyed, copies of any supplemental documents required to delineate property lines and title will also be submitted.  A report, if needed, identifying any title defects encountered for the affected parcels will be included with the deed copies.  This submittal will also include all applicable tax maps.

 


In addition, no more than fifteen (15) working days prior to the Submission of R/W Plans (1507), the property ownership data will be checked and verified.  Copies of deeds for any new ownership transactions that impact the project will be submitted to the District Real Estate Administrator.  An in-depth field review of the project will also be conducted within the same fifteen (15) working day period to assure that no topographic features, structures and/or utilities have been changed or omitted.  The right of way plan and descriptions will be revised to accurately reflect the above information.  The actual dates that the ownership data and topography were checked and verified will be shown on the plans and in the submittal letter with the Submission of Right of Way Plans (1507).

 

The DBT will determine specifications regarding individual County requirements pertaining to the preparation of legal descriptions, plats and any other required documents.  All legal descriptions will be prepared in accordance with standards of the County(s) involved and will be pre-approved by the County(s) where permitted.  Prior to the Submission of R/W Plans (1507), the DBT will submit the legal descriptions to the appropriate County, with a copy to the District Real Estate Administrator, for pre-approval.  The DBT will then verify the County’s response at the Submission of R/W Plans (1507).  The DBT will assure mathematical closure of each right of way parcel and provide the District Real Estate Administrator with a computer printout demonstrating this fact.  The DBT will be responsible for revision/correction of any instruments deemed unacceptable for transfer by the County Recorder’s Office.

 

At the Submission of R/W Plans (1507), the DBT will submit final right of way tracings.  In addition, the DBT will submit legal descriptions in electronic format using ODOT’s current, standard version of word processing software with size, point type and font as specified in the Real Estate Policies and Procedures Manual or as directed by the District Office.  This submittal will include four (4) full size sets of right of way prints, four (4) half size sets of right of way prints, four (4) half size sets of construction prints (most current) and two (2) sets of legal descriptions.

 

During the acquisition phase, all revisions to the construction plans, right of way plans and/or legal descriptions deemed necessary by ODOT will be performed by the DBT, as directed, in such a manner as to facilitate the timely acquisition of right of way.

 

ODOT’s District Office will be responsible for preparing the Certificate of Rights of Way to the FHWA.

Abutments founded on spread footings not on bedrock are not permitted, unless they are founded below the stream thalweg.

Piers

Are the piers to be retained or replaced?  Refer to the BDM, section 403.

For piers that are functioning properly and are in good shape the requirements to meet code requirements can be waived if the superstructure loads are not increased by more than 15% and the new beam lines are placed in the same bearing location (except wall type) as the existing beam lines.  Should be analyzed for each structure, prior to scope.

Piers on spread footings, not on bedrock, in a stream shall be replaced.

If the footings are to be retained and are supported on piles, are the pile logs available.

 

NEW STRUCTURE

Superstructure

            Note: A588 weathering steel is now permitted on any structure.

            Box beams - can the superstructure be non-composite or is composite required.

Is a specific size (length) structure desired.

            If so, give the minimum acceptable length (begin - end stations)

Are utilities to be banned from the structure?  If so, no utilities shall be placed on the bridge.  The BDM suggests to keep utilities off.

Substructure

Should any substructure type be ruled out?

            Example - No capped pile piers for overpass structures.           

            Any need to limit the abutment type?

            The BDM does not limit the use of spread footings except when in streams.

16.2  SIGNING

 

THIS SECTION SHOULD INCLUDE ANY DISTRICT PREFERENCES, TRADITIONAL PLAN NOTES, SPECIAL PROVISIONS, AND ALL WORK DESCRIPTIONS AND REQUIREMENTS TO BE ENFORCED DURING CONSTRUCTION. .

 

THE FOLLOWING IS A CHECK LIST OF ITEMS THAT SHOULD BE CONSIDERED BY THE DISTRICT AND ADDED ON TO THIS SECTION.

 

Signs - The suitability of the existing signing should be evaluated.

 

a.         Are all of the existing signs adequate?

b.         Are the existing signs in conformance with the OMUTCD?

c.         Are there nonstandard signs used that should be replaced with standard signs?

d.         Are larger signs needed?

e.         Should additional signs be installed?

f.          Should existing unnecessary signs be permanently removed?

g.         Are there optional sign treatments that should be considered?

h.         Are there signs in less than optimal locations that can be relocated to improve effectiveness?  This would include signs located in vertical or horizontal curves, or obscured by overpasses or other structures.

i.          Are there signs that should be supplemented with hazard identification beacons?

 

Sign Supports - The suitability of the existing supports should be evaluated.

 

a.         Are the existing supports adequate for the sign area?

b.         Are the existing supports in the proper locations?

c.         Are the existing supports in good structural condition?

d.         Do the existing supports in exposed locations meet current breakaway criteria?

e.         Are the existing nonbreakaway supports adequately protected by guardrail or barrier?

 

Flat Sheet Signs

 

a.         Typically, all flat sheet signs on a project should be upgraded, even if some have not reached the end of their useful life.

b.         It should be made clear to the contractor that ODOT maintains the STOP signs on the intersecting non-state roads.

c.         The road name signs on conventional state highways are usually maintained by the local jurisdiction.  ODOT can decide to install road name signs (including advance signs) if desired.  This can be selectively done on an intersection by intersection basis.

d.         Optional signs that are to be included should be sufficiently described.  This includes destination signs, cross road and side road intersection warning signs, other warning signs, generator signs, and recreational and cultural interest area signs.

e.         If supplemental left side mounted signs are to be used at any locations, the District should specify where.

f.          If oversized signs are to be used at any locations, the District should specify where.

g.         If some signs will be provided by ODOT for contractor installation, such as Ohio Byway signs, this needs to be clearly indicated.

h.         Specify the minimum mounting height and lateral offset if different from the OMUTCD and SCD requirements.  If a maximum mounting height is desired, this needs to be specified as well.

i.          If some flat sheet signs will be mounted overhead, this needs to be specified.

j.          Typically, removed flat sheet signs should be disposed of by the contractor.

 

 

Extrusheet Signs

 

a.         Typically, all extrusheet signs on a project should be upgraded, even if some have not reached the end of their useful life.

b.         Optional signs that are to be included should be sufficiently described.  This includes additional advance guide signs, generator signs, and recreational and cultural interest area signs.

c.         Specify the minimum mounting height and lateral offset if different from the OMUTCD and SCD requirements.

d.         Specify where extrusheet signs will be mounted overhead.

e.         Specify that wide, narrow signs, such as destination signs on conventional highways, be made of extrusheet.

f.          For freeway and expressway mainline designable guide signs, the element sizes (level of signing) should be indicated if it may be unclear to the contractor what level would be required, or if the District desires to use a higher level than required by the OMUTCD.

g.         If some signs will be provided by ODOT for contractor installation, such as state line signs, this needs to be clearly indicated.

h.         For freeway and expressway guide signing, the District should scrutinize the current signing, and decide if different signing strategies should be employed.  This includes the increased use of sign spreading, interchange sequence signs, and diagrammatic signs (OMUTCD Sections 2V-8, 2V-12 and 2V-14, respectively).

i.          For freeway and expressway guide signing, unnecessary pull-thru signs should be eliminated.  (See OMUTCD Section 2V-7.)

j.          Freeway and expressway entrance ramp approach signing that is located beyond the right-of-way and is not on a rural state route or state route extension in a municipality is not the responsibility of ODOT.  If this signing will be included, it should be clearly indicated.  (Consent of the local jurisdiction may be required.)

k.         TODS and logo signs are installed and maintained by Ohio Logos, Inc., under contract with and in locations approved by ODOT.  Under the terms of the contract, Ohio Logos can be required to temporarily remove or relocate the signs during construction.  They can also be required to permanently remove or relocate the signs.

l.          Typically, removed extrusheet signs should be returned to the ODOT Sign Shop.

 

Ground Mounted Post Supports

 

a.         Typically, all ground mounted post supports should be upgraded.  All post supports in exposed locations not meeting current crash testing requirements (e.g. back-to-back u-channel posts) must be replaced.

b.         For no. 2 and no. 3 posts, direct driven u-channel, direct driven square post, and square post in anchor base are considered as equivalents on SCD TC-41.20.  If the District prefers one support system, this needs to be described.  (Even if square post is specified for flat sheet signs, the District may want to consider allowing u-channel for small extrusheet signs to simplify sign attachment to support.)

c.         If the District wants a breakaway connection used, this needs to be described in detail.

d.         Typically, removed ground mounted post supports should be disposed of by the contractor.

 

Ground Mounted Beam Supports

 

a.         Will the existing supports be reused?  Galvanized steel structural beam sign supports can oftentimes be reused if they are in good condition, in the correct location, and the replacement sign is of a comparable size.

b.         For structural beam supports, the slip base and alternate connection as shown on SCD TC-41.10 are considered as equivalents.  The slip base connection will usually be supplied due to it’s lower cost.  If the District wants to require the exclusive use of the alternate connection, this needs to be specified.

c.         Structural beam sign supports subject to multidirectional impacts at intersections should use the alternate connection on sizes larger than S4 x 7.7.

d.         If the District wants to use a different support system, such as the laminated veneer wooden beams, this needs to be described in detail.

e.         Typically, removed ground mounted beam supports should be disposed of by the contractor.

 

Overhead Supports

 

a.         Due to the high cost of overhead supports, the District will need to determine in advance which overhead supports will be reused in place, relocated, or replaced, and where new overhead supports will be installed.

b.         Overhead sign supports should be inspected by the District to determine their condition and structural adequacy.

c.         The steel portions of existing structures that will be reused can be recoated using the standard four step process developed for this purpose.  This process can also be applied to new structures.


d.         Specify the required vertical clearance of overhead signs.  OMUTCD Section 2U-6 defines this as seventeen feet, except when other structures use a lesser clearance.  In this case, the vertical clearance does not need to be greater than one foot higher than the minimum design clearance of other structures.  However, whenever possible, a seventeen foot clearance is recommended.

e.         Consideration should be given to revising median end frame foundations that are encased in barrier wall assemblies (SCD TC-21.41) to the top of the concrete barrier (SCD TC-21.40).  The barrier wall assembly can result in increased maintenance as this design will tend to accumulate debris that will need to be periodically removed to avoid vegetation growth.

f.          If end frames and poles located in the clear zone do not meet current requirements for shielding (guardrail or barrier), a determination will need to be made regarding appropriate remedial measures.

g.         The use of aesthetic treatments should be considered in accordance with ODOT policy.

h.         Sign attachment assemblies, which include the z-bar, u-bolts, clamps and miscellaneous hardware, can be reused if they are in good condition and the replacement sign is the same size as the existing sign.  If not, these should be replaced.

i.          Specify the extent that sign lighting will be utilized.  Existing sign lighting should be upgraded to that detailed on SCD TC-31.21.  Luminaire support assemblies of current design and in good condition can be reused if the replacement sign is the same size as the existing sign.  Consideration should be given to the replacement of the luminaires and ballasts, and to the rewiring of the signs.

j.          If the maintaining agency wants remote ballasts used at all locations, specify this requirement.

k.         Typically, removed overhead supports should be disposed of by the contractor.
