Changes in the number of units SHOWN in the SCHEDULE OF ITEMS may be authorized under any of the following conditions:

a. As a result of changes in the work authorized by the Contracting Officer.

b. As a result of the Contracting Officer determining that errors exist in the original design data used to determine designed quantities that cause a pay item to change by 15 percent or more.

Cooling Tower Maintenance

c. As a result of the Contractor submitting to the Contracting Officer a written request showing evidence of errors in the original design data used to determine design quantities that cause a pay item total to change by 15 percent or more.

The evidence must be verifiable and consist of calculations, drawings, or other data that show how the designed quantity is believed to be in error.

2. Actual Quantities (AQ) - These quantities are determined from measurements of completed work.

3. Vehicle Quantities (VQ) - Quantities measured or weighed in hauling vehicles.

4. 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.
