Monday through Friday, excluding County-observed holidays and weekends. No work shall proceed outside these hours without 72 hours prior notice (minimum) and written authorization by the County’s PROJECT MANAGER. However; the COUNTY reserves the right to establish work hours based on traffic volumes, congestion, or other situations that will interfere with the normal flow of traffic.

Temporary Traffic Control Permits will be issued by the COUNTY, as described later in these Supplemental Specifications. The TTC Permits indicate the allowable hours for operation within the actual roadway limits for each road or portion thereof in each project’s work order(s). The CONTRACTOR may request alternative work hours, based on the allowable hours established by the TTC Permit(s). The approval of alternate work hours for each project is subject to the same authorization described above and will be based on a standard 8-hour shift as provided by the normal work hours. These provisions allow daytime and nighttime shifts, based on the allowable hours indicated by the TTC Permit. Further changes to the approved work hours require a formal request by the CONTRACTOR for the TTC Permit to be amended by the COUNTY and the aforementioned written authorization by the County’s PROJECT MANAGER. If approved, an amended TTC Permit will be issued to the CONTRACTOR.

As long as the work is on schedule, the PROJECT MANAGER is not obliged to consider a shift longer than 8 hours or additional workdays beyond those described above. However, if the work is deemed to be behind schedule, the PROJECT MANAGER may approve longer shifts and/or additional shifts based on the approval of a recovery schedule submitted by the CONTRACTOR.

At the discretion of the PROJECT MANAGER, additional costs incurred by the COUNTY for overtime wages and/or employing additional staff are subject to reimbursement by the CONTRACTOR to the COUNTY.

1.08R Contract Estimated Quantities Unit quantities indicated in the Bid Proposal section are provided as a means of comparing bid proposals and as a basis for award. However, these quantities are estimated, and actual unit quantities may vary during the term of this contract. The COUNTY does not guarantee a minimum usage on this contract.

Bidders are cautioned against predicating their bid prices on an assumed scope of work or estimated bid quantities. The amount of award represents only the upper dollar limit beyond which no further work shall be ordered, except as may be approved by the BOCC, through Change Order. It is not known how much or how little work will be ordered during the term of this contract.

The CONTRACTOR acknowledges that actual quantities may be significantly more or less than those indicated on the bid. The CONTRACTOR agrees that he will not make any claim for damages or for loss of profits because of a difference between the quantities shown on the bid form and the quantities of work actually ordered.

Total purchases shall not exceed the amount awarded by the Board, and no work shall be commenced which is not provided for by the provisions of the contract.

Basis for payment shall be actual field measurement, not estimated bid or plan quantities. The dollar amount of payment shall be determined by multiplying the contract unit price for an item by the field measured actual quantity.

Because quantities are estimated and actual requirements will not be determined until time of need, Items 5.8 and 5.9 of the General Terms and Conditions are hereby modified to remove the necessity for formal change order in the event of quantity overruns or under runs, provided that total purchases do not exceed the amount of award.

1.09R Incidental Items Miscellaneous or incidental items such as dewatering, cutting, patching, grading, saw-cutting, electrical hardware, bolts, nuts, fittings, etc., or other ancillary items may be required to complete the construction as indicated on the plans or in the scope of work.

The contractor shall protect from any damage all existing structures, underground piping, benchmarks, trees, and other facilities. The CONTRACTOR will be held responsible for damage to such existing facilities. In the event of interruption of water, wastewater or other utility services as a result of accidental breakage, exposure, or lack of support, the CONTRACTOR shall promptly notify the proper authority and cooperate with the authority in the prompt restoration of service. If water or wastewater service is interrupted and the CONTRACTOR is performing or assisting the repair work, the CONTRACTOR shall work continuously until the service is restored.
