Work performed to retrofit existing LPSS facilities may also include the removal and/or rehabilitation of existing tanks and other LPSS equipment.

The number of future LPSS installations is unknown. However, the County has installed an annual average of 50 LPSS installations. The number of existing LPSS facilities to be retrofitted is unknown.

Except as otherwise provided herein, the CONTRACTOR shall furnish all labor, tools, vehicles, supplies, equipment, materials, and permits to accomplish the Work contemplated in these Contract Documents in an expeditious and workmanlike manner.

1.4. TECHNICAL SPECIFICATIONS

All work regardless of the scope, shall be performed in strict accordance with the Hillsborough County Standard Specifications For Construction (latest edition) and/or Hillsborough County Water, Wastewater, and Reclaimed Water Technical Manual and/or Technical Specifications (latest editions) and/or Hillsborough County Standard Pump Station Drawings, and/or Utility

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

In all conditions, the most stringent requirement/specification as determined by the Project Manager shall apply to the project. It is the Contractor’s sole responsibility to purchase/locate at their expense the necessary drawings, specifications, and technical guideline material to perform the necessary scope of work and be advised of any updates, modifications, alterations, and any deviations of the above mentioned during the life of the contract.

1.5. BASIS FOR AWARD AND CONTRACT PRICE

Award will be made to the responsive and responsible bidder meeting specifications who submit the lowest total bid price, based on the estimated quantities included herein.

For budgetary and other reasons, the total amount of award for this Contract will be established at $4,000,000 or the recommended total bid price whichever is less.

If the recommended total bid price is greater than the award amount of $4,000,000, authorized work (and bid estimated quantities) will be reduced accordingly.

Notwithstanding the above, the actual amount of work to be performed is not known, and the County only guarantees a minimum of $10,000 usage on this Contract.

The amount of award referenced in the above statements is defined as the upper dollar limit beyond which no further work may be authorized without approval of the Board. Specifically, the amount of award shall not be construed as indicating the actual value of work anticipated by the County under this Contract. The actual value of work to be authorized is not determined until the time of need for that work occurs, and may be significantly less than the amount indicated in the award.

1.6. UNBALANCED BIDS

For unit-price contracts, a balanced bid is one in which each bid item is priced to carry its share of the cost of the work and also its share of the contractor’s profit.

The County reserves the right to reject any bid in which unit prices, in the sole opinion of the County, are unbalanced. In addition, where the County has decided to make an award, it further reserves the right to non-utilize a particular line item that is, in the sole opinion of the County, excessively priced. The County reserves the right to obtain that item from another source.

Determination of an unbalanced bid or excessively priced line item is made utilizing one or more of the following:

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

SC - 3

1) A comparison of prior bid prices with recent bid prices for the same or similar item or service.

2) A comparison with published price lists published market prices, similar indices and discount or rebate arrangements.

3) A comparison of proposed prices with independent cost estimates.

4) A formal cost study using appropriate professional experts.

5) A comparison of the proposed bid price with the average unit price bid.

6) The price for the item or service is not priced to carry its share of the cost of the work and also its share of the contractor’s profit.

1.7. CONTRACT COMMENCEMENT AND EXPIRATION

The Contract resulting from this Solicitation Document shall commence on the date specified on the Contract Commencement Notice and shall expire upon completion of all authorized Work. The Work Order Authorization Period will expire on the second anniversary of the Contract Commencement Notice, or when the actual authorized work equals the awarded Contract amount, whichever occurs earlier.

Expiration dates for both the Contract and the Work Order Authorization Period can only be adjusted as outlined in the Contract Renewal Clause.

Bid Proposal item unit prices shall remain firm and non-negotiable during the life of the

Contract, including any renewal periods. Bid Proposal item unit prices can only be adjusted under the conditions outlined in the Cost Escalation Clause.

1.8. CONTRACT ESTIMATED QUANTITIES

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 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 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.

SC - 4

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.

1.9. AUTHORIZATION OF WORK
