1.2 – Method of Measure One of the following methods of measurement for determining final payment is DESIGNATED on the SCHEDULE OF ITEMS for each pay item.

A. Actual Quantities (AQ): The quantity to be paid is the quantity listed in the bid schedule. The contract quantity will be adjusted for authorized changes that affect the quantity or for errors made in computing this quantity. If there is evidence that a quantity specified as a contract quantity is incorrect, submit calculations, drawings, or other evidence indicating why the quantity is in error and request in writing that the quantity be adjusted.

Final payment will be made for the actual quantities at the unit price shown in the SCHEDULE OF ITEMS, subject to the Variation in Quantities Provision.

B. Lump Sum Quantities (LSQ): These quantities denote one complete unit of work as required by or described in the contract, including necessary materials, equipment, and labor to complete the job. They will not be measured.

C. Estimated Quantity (EQ): If the quantity of a unit-priced item in this contract is an estimated quantity and the actual quantity of the unit-priced item varies more than 15 percent above or below the estimated quantity, an equitable adjustment in the contract price shall be made upon demand of either party. The equitable adjustment shall be based upon any increase or decrease in costs due to the variation above 115 percent or below 85 percent of the estimated quantity. If the quantity variation is such as to cause an increase in the time necessary for completion, the Contractor may request, in writing, an extension of time, to be received by the Contracting Officer within 10 days from the beginning of the delay, or within such further period as may be granted by the Contracting Officer before the date of final settlement of the contract. Upon receipt of a written request for an extension, the Contracting Officer shall ascertain the facts and make an adjustment to extend the completion date as, in the judgement of the Contracting Officer, is justified.

1.3 – Pay Units:

One of the following methods of measurement for determining final payment is DESIGNATED on the SCHEDULE OF ITEMS for each pay item.

A. Lump Sum (LS): This pay unit denotes complete unit of work as required by or described in the contract, including all necessary materials, equipment, and labor to complete the job. They will not be measured.

B. Linear Feet (LF):Is a standard unit of measurement representing exactly 12 inches in a straight line.

C. Centum Square Feet (CSF): Is a standard unit of measurement equal to 100 square feet.

D. Each (EA): These quantities denote one complete unit of work as required by or described in the contract, including all necessary materials, equipment, and labor to complete the job. They will not be measured.
