This work consists of maintaining and protecting vehicular and pedestrian traffic according to these provisions. For through traffic, the Special Provisions or the plans will designate whether the highway will be closed with detours, roads, and run-arounds provided or whether traffic will be maintained through all or portions of the project.
Vehicular and pedestrian ingress and egress for all property adjacent to any improvement shall be provided at all times.
Contractor maintenance responsibilities, including pothole patching, begins for a section of highway when the Contractor begins the work in that section and ends with the acceptance of the work under 109.11 or 109.12. The two directions of a divided highway are considered separate highway sections and the start of work on one direction does not begin maintenance responsibilities on the other direction.
The traffic control shall conform to the requirements of the plan, standard construction drawings shown on the plans, and the OMUTCD for Streets and Highways, hereinafter called the Ohio Manual, for the installation, maintenance, and operation of all traffic controls and traffic control devices. When the plans or standard construction drawings do not cover a specific traffic control situation, the necessary traffic control devices shall be placed according to the Ohio Manual and procedures required by the Ohio Manual shall be implemented.
The OMUTCD (Ohio Manual on Uniform Traffic Control Devices) has three levels of compliance to indicate the type of standard and whether it is mandatory, recommended, or optional:
· All mandatory conditions are listed under the section heading “Standard.”
· All recommended conditions are listed under the section heading “Guideline.”
· All allowed conditions are listed under the section heading “Option.”
· A fourth grouping, “Support,” was added to include statements that were not mandatory, recommended, or optional, but rather general information.
Supplement 1061 prequalifies the portable changeable message boards. Only two panel of information shall be allowed.
Drums, signs, sign supports, barricades, impact attenuators, and other traffic control devices that are certified to meet NCHRP 350 safe-crash standards, or as modified by Contract Documents, shall be used. Do not allow heavy, non-yielding devices or supports that do not conform to the current standards of NCHRP 350, unless allowed by Contract Documents.
Ensure the drums are furnished with Type G, reboundable reflective sheeting, which complies with the requirements of 730.191. Ensure that owner identification markings on construction drums are no more than 1 inch (25 mm) in character height and are located at least 2 inches (50 mm) below the reflectorized bands or on the top or bottom horizontal surfaces of the drum. Ensure the drums are ballasted according to the manufacturer’s recommendations.
If equipment, vehicles, and material are stored or parked on highway rights-of-way, they shall be located no less than 6 feet (2 m) behind existing guardrails or no less than 30 feet (9 m) beyond the traveled way, unless otherwise permitted by the Engineer. At night, if any such material or equipment is stored between the side ditches or between lines 6 feet (2 m) behind any raised curb, they shall be clearly outlined with dependable lighted devices that are approved by the Engineer.
Whenever one-way traffic is established, at least two flaggers shall be used, unless the Engineer authorizes otherwise, and signs, cones, barricades, and other traffic control devices shall be erected according to the Ohio Manual. Flaggers shall maintain positive and quick means of communication at the opposite ends of the restricted area.
The Contractor may use either a Type 1 or Type 2 mix of Item 448 asphalt concrete PG 64-22, or an asphalt concrete surface course the Engineer approves. Surface course materials shall be placed where the Engineer directs for maintenance of the existing pavement, shoulders, or structures.
Where materials are placed in small quantities or under adverse conditions, the Engineer may waive specification requirements for placing and finishing if, in the judgment of the Engineer, it is determined that the Contractor can obtain satisfactory results in providing a smooth and durable pavement surface.
If, in the opinion of the Engineer, the Contractor is not furnishing proper maintenance of traffic facilities and proper provisions for traffic control, the Department may take the necessary steps to place them in proper condition. The Department will deduct the cost of such services from any money that may be due or become due the Contractor.
The Department will measure Work Zone Marking Signs as the number of sign installations, including the sign, necessary supports, and all attachment hardware. The Department will include all other work zone signs under Maintaining Traffic unless separately itemized.
The Department will measure Work Zone Pavement Markings complete in place, by class and material, in the units designated.
The Department will measure line quantities as the length of the completed stripe, including gaps, intersections, and other sections of pavement not normally marked.
Unless separately itemized, the lump sum price bid for Maintaining Traffic shall include the cost of removing conflicting pavement markings and layout, application and removal of pavement markings, maintaining the existing highway in a safe condition for public use, and removing abrasive and salt residue remaining from snow and ice control performed by the Department or local governments. The lump sum price bid for Maintaining Traffic shall also include the cost of providing flaggers and their equipment, while maintaining the equipment in an acceptable condition, and subsequently removing the following work zone traffic control items, as required by the Contract Documents:
1. Signs, supports, and warning lights.
2. Drums, cones, gates, barricades, and vertical panels.
3. Flashing arrow panels.
4. Work zone traffic signals.
5. Lighting for work zone signals and flaggers.
If traffic permanently damages beyond use, any of the following items, the Department will compensate the Contractor for the fair market value of the damaged item according to 109.05, provided the Contractor has pursued, but failed to obtain compensation from the motorist. Follow the procedures given in 107.15 for traffic damage compensation to completed permanent items of work. Obtain compensation from the motorist before requesting compensation from the Department.
1. Flashing arrow panel.
2. Work zone signal, pole, or controller.
3. Lighting unit or pole.
4. Changeable message sign.
5. Work Zone Impact Attenuator.
The lump sum price bid for Detour Signing includes the cost of the Contractor furnishing, installing, maintaining, and removing the detour signing shown on the plans and their necessary supports.
The Department will pay for the following items under their associated item numbers: 502, “Bridges”; 615, “Roads and Pavement”; 622, “Portable Concrete Barrier.” The Department will pay for aggregate and calcium chloride authorized by the Engineer and used for Maintaining Traffic under Items 410 and 616.
