https://www.hillsboroughcounty.org/en/businesses/land-development/technical

Unit quantities 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 greatly during the term of this contract. THE

BIDDER IS ADVISED THAT THE TOTAL QUANTITY OF WORK REQUESTED MAY BE LESS

THAN THE QUANTITY ESTIMATED, AND IN FACT THE COUNTY ONLY GUARANTEES A

MINIMUM OF $10,000 USAGE ON TIDS 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 Board through a Change Order. It is not known how much or how little work will be ordered during the term of this contract.

Bidder acknowledges that actual quantities may be significantly less than those indicated in the bid, and agrees that, as the Contractor, he/she will not make any claim for damages or for loss of profits because of a difference between the quantities bid and the quantity of work actually ordered.

Work Order pricing shall be based on actual field measurement, not estimated bid or planned quantities.

Because quantities are estimated and actual requirements will not be determined until time of need, Section "Change in the Work" and Section "Change of Contract Price" of the General Terms and Conditions are hereby modified to delete the necessity for a Change Order in the event of line-item quantity over or under runs, provided that total purchases do not exceed the amount of award.

1.4 WORK ORDER ROTATIONAL PROCEDURE

In the event the County awards this contract to more than one Contractor, Work Orders will be issued on a determination of the best overall value for the County.

Value shall be determined by the Project Manager based on the following factors; Scope, Schedule, and Cost.

The Project Manager shall develop a preliminary scope, schedule, and cost estimate for each task order and determine the best value for the County. If it is determined to be in the best interest of the County, a Work Order may be awarded to the Contractor with the lowest time estimate (schedule) for the completion of the work. The Project Manager shall continue the Work Order Assignment Procedure described herein for the duration of the Contract, including all subsequent renewal periods.

1.5 AUTHORIZATION OF WORK

No work may be performed under this term contract except as authorized by a Work Order issued by the Public Utilities Department Director, or designee and a Purchase Order.

Verbal authorization may be given when immediate response conditions occur at night and/or on weekends and followed-up with a written authorization within 24 to 48 hours of the occurrence.

1.6 AUTHORIZED CONSTRUCTION DAYS

It is anticipated that this contract may include projects (Work Orders) of both short and long duration. Prior to issuance of a particular Work Order, the Project Manager and the Contractor will mutually agree as to a fair and reasonable anticipated number of days necessary to achieve Substantial and Final Completion on all Work Orders.

Once the number of days has been determined and mutually agreed to, a Work Order may be written as specified in the Contract Documents. The liquidated damages amounts specified in the General Terms and Conditions, entitles the County to assess liquidated damages per calendar day of delay, excluding circumstances that are beyond the control of the Contractor as outlined in the contract. In addition, failure on the Contractor to complete the Work Order work within the time specified in the Work Order may result in no further Work Orders being issued under this Contract and/or termination of this Contract and/or any pending Work Order(s).
