Scope of work 1.06 INCREASE OR DECREASE OF WORK B. Delete and Replace with the Following: Unless such alterations, increases, or decreases materially change the character of the work to be performed or the cost thereof, the altered work shall be paid for at the same unit prices as other parts of the work. Quantity changes, for major items as defined by COA Supplemental Specification 1010.1.03, amounting to 20% or less of the total bid for an item shall not affect the unit price of that item. When a major item of work, is increased in excess of 120% or decreased below 80% of the original contract quantity. Any allowance for an increase in quantity shall apply only to that portion in excess of 120% of the original contract item quantity.

The difference between 80% of the contract quantity and the actual installed quantity (50%) is 30 units. 20 units will be paid at the contract price 30 units will be paid at a new, agreed to, unit price.
