SPECIAL PROVISION
Utility Conflicts
Utility companies having known facilities that conflict with the construction of this
project will be directed by the Department to adjust or relocate their facilities and will be
notified of the contract award.
Conform to all the requirements of the Specifications as they relate to cooperation with
utility owners and the protection of utility installations that exist on the project. Refer to
the requirements of Section 107, Legal Regulations and Responsibility to the Public, with
particular attention to Subsection 107.21.
Coordinate The Work with any work to be performed by others in any right of way
clearance and arrange a schedule of operations that will allow for completion of the
Project within the specified contract time. Where stage construction is required, notify
the utility owner when each stage of work is completed and the site is available for utility
work to proceed.
Information concerning utility facilities known to exist within the project limits,
including the list of owners, is available for reference.
Under Georgia Code Section 32-6-171, utilities are required to remove or relocate their
facilities. The Department is required to give the utility at least 60 days written notice
directing the removal, relocation, or adjustment and the utility owner is required to begin
work within the time specified in the utility's work plan or revised work plan.
Upon request, copies of all approved Work Plans submitted by utility companies having
facilities on this project will be made available for examination by the Contractor at the
Department's District Office. Utility Adjustment Schedules, when submitted to the
Department by the utilities, will be made available to the Contractor after the Notice to
Contractors has been posted by the Office of Construction Bidding Administration. The
Contractor is responsible for considering in its bid all existing and proposed utility
locations and the removals, relocations, and adjustments specified in the Utility's Work
Plan.
For this Project, Utility Owners that are required to remove, relocate, or adjust their
facility to accommodate the construction of this Project may be liable to the Contractor
for damages or delay costs resulting from the Utility Owner's failure to clear conflicts

within the time specified in the approved Utility Work Plan. If the Utility Owner is
unable to submit and obtain Department approval of a revised Work Plan or fails to
complete the removal, relocation, or adjustment of its facilities in accordance with the
approved Work Plan, the Utility Owner may be liable to the Department, or the
Contractor, for damages or delay costs.
In accordance with Subsection 105.06 of the Specifications, the Department is not liable
for payment of any claims due to utility delays, inconvenience or damage sustained by
the Contractor due to interference of any utilities or appurtenances, or the operation of
moving them.
In any case in which the Contractor believes that it will be entitled to damages or delay
costs from the Utility Owner in accordance with O.C.G.A. 32-6-171, the Contractor shall
provide written notice to the Utility Owner and the Department within ten (10) days from
the time of the dispute or potential dispute is identified. The Contractor shall follow the
Procedures for Utility Damages or Delay Costs outlined in the latest edition of The
Utility Accommodation Policy and Standards Manual. Failure to follow the above will
result in waiver of the Contractor's claim against the Utility Owner for damages or delay
costs.
In accordance with Subsection 107.21.G delays by utilities will continue to be considered
by the Department in charging Contract Time. For purposes of applying provisions of
this paragraph, railroads and the Metropolitan Atlanta Rapid Transit Authority (MARTA)
are considered utilities.

Section 108 - Prosecution and Progress
108.07 Determination of Contract Time
F. Extension of Contract Time
Retain subsection and add the following:
The Contract time includes due allowance for unsuitable weather days during which the work
cannot be performed. For purposes of calculating Contract Time extension requests based on
unsuitable weather sufficient to prevent performance of the work, the Contractor shall first refer
to the unsuitable weather days contemplated under the Contract, in accordance with the schedule
of monthly anticipated unsuitable weather delay days below. The Contractor shall not be entitled
to any extension of Contract time for unsuitable weather unless Contractor encounters actual
unsuitable weather in excess of those days set forth in the schedule below:
January - 10 days February - 9 days March - 7 days April - 5 days
May - 5 days June - 4 days July - 4 days August - 4 days
September - 4 days October - 5 days November - 6 days December - 10 days
The schedule above represents a standard Monday through Friday (5 day) work week. No
extension of Contract Time will be considered for unsuitable weather on Saturdays, Sundays, and
Holidays.
In addition to any other project records required in this Contract, the Contractor shall provide a
monthly record to the County summarizing any unsuitable weather in excess of those anticipated
days indicated in the above schedule for which a request for a weather-related time extension will
be made. The record shall state with particularity a description of the unsuitable weather as well
as a description of the nature and extent of any delay caused by such weather. The Contractor
shall submit the request for weather-related time extension within seven (7) days of the calendar
month end, and such request shall be supported by documentation required by the County
including, but not limited to, official weather reports. Days requested for weather-related time
extensions will be offset against any days available from months with fewer unsuitable weather
days than those provided for in the schedule. Weather-related Contract time extension requests
will not be evaluated until the end of the project.

Weather-related Contract time extension requests will not be considered if Contractor has not
actively pursued the work continuously since issuance of Notice to Proceed. Contractor's failure
to utilize available days shall not warrant an extension of contract time due to unsuitable weather.
Any and all unsuitable weather-related delays shall be non-compensable, and the sole and
exclusive remedy of the Contractor in the event of any such delay is an extension of Contract
Time.
Should the Engineer find that the Contractor is due a Contract Time extension, the Director of the
Cobb County Department of Transportation, or his designee, shall have the authority to execute
change orders for the extension of Contract Time of behalf of the Department, provided no
additional compensation is requested and all other terms of the Contract remain unchanged.
108.08 Failure or Delay in Completing Work on Time
Delete the Schedule of Deductions for Each Day of Overrun in Contract Time table shown in Section
108.08 and replace with the following:
An overall Completion Date of Three Hundred Sixty-Five Days (365) calendar days has been
established for this Project.
Failure to complete the construction in accordance with the above will result in the assessment of
Liquidated Damages at the rate of $2,000.00 per calendar day or portion thereof.

signs, barricades, lights, signals, cones, pavement markings and other traffic control devices and shall include flagging
and other means for guidance and protection of vehicular and pedestrian traffic through the Work Zone. This Work
shall include both maintaining existing devices and installing additional devices as necessary in construction work
zones.
The Contractor shall be responsible for the maintenance of traffic signals and Advanced Traffic Management System
(ATMs) devices from the time that the system is modified until final acceptance. The maintenance of traffic signals and
ATMs devices that are not a part of the Work and that are not in conflict with any portion of the Work shall not be the
responsibility of the Contractor. However, the Contractor is still responsible for damages to all devices that they or
their subcontractors cause, in accordance with Section 107 and other Specifications.
When any provisions of this Specification or the Plans do not meet the minimum requirements of the MUTCD, the
MUTCD shall control. The 2023 Edition of the MUTCD including revisions shall be in effect for the duration of the
project.
All traffic control devices used during the construction of the project shall meet the standards utilized in the MUTCD,
and shall comply with the requirements of these Specifications, Georgia Construction Standards and Details, Project
Plans, Design Manuals, and Special Provisions.
The needs and control of all road users (motorists, bicyclists and pedestrians within the highway right-of-way and
