PART 1 - GENERAL

1.1 SUMMARY

A. Section Includes:

1. General provisions on unit prices and quantities.

2. Listing of the various bid/pay items in the Project, together with criteria for measuring

Unit Price Work for payment.

1.2 GENERAL PROVISIONS ON UNIT PRICES AND QUANTITIES

A. Quantities:

1. Quantities of Unit Price Work indicated in the Bid Form and in the Contract (at the time the Agreement was signed by the parties) are estimates for purposes of pricing and comparison of Bids.

2. The Contracting Officer (CO) does not represent, either expressly or by implication, or agree that the nature of materials encountered below ground surface or in concealed areas, or actual quantities of Unit Price Work required, will correspond with the quantities in the Contract at the time the Agreement was signed by the parties. The CO reserves the right to increase or decrease quantities, and to eliminate quantities, as the CO may deem necessary or as may be necessary due to Site conditions encountered.

3. Quantities eligible for payment will be actual quantities furnished and installed (as applicable) in accordance with the Contract Documents, within the pay limits shown or indicated, as measured by the COR (or other entity so empowered in the Contract

Documents) and recommended for payment by the COR.

4. At Contractor’s expense, Contractor may independently verify quantities measured by the

COR for payment. Should Contractor disagree with quantities measured and recommended for payment by the COR, submit appropriate Change Proposal (appealing the COR’s measurements) indicating the specific reasons for Contractor’s appeal, with detailed reasons therefor and associated calculations and estimates, in accordance with the Contract Documents.

5. Quality Overruns:

a. When the quantity of a pay item of Unit Price Work eligible for payment exceeds the pay item’s quantity included in the Contract, the CO will pay for quantities that exceed those in the Contract only while the estimated total payments to

Contractor under the Contract will not exceed the Contract Price. Otherwise, a

Change Order is required to modify the associated quantity in the Contract, thus changing the Contract Price.
