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.
