New Item#108—Equitable Adjustment. A changed condition due to soft,moist soils on Colby Avenue resulted in the sides of trenches collapsing into the trench,during sewer main and side sewer pipe trench excavation. This resulted in additional structural roadway excavation removals, soil excavation removals,haul costs, and significantly slowed completion of the project resulting in additional working days to be added to the Contract Time. Once the Change of Condition was known, the Contractor provided the Owner written Notice, as is a Contract requirement, when seeking added costs. Toward the end of construction, once the Contractor had established the cost impacts resulting from this Changed Condition situation, submitted an Equitable Adjustment request in the amount of $348,562.18. City Construction Management upon receipt of this Equitable Adjustment request, review it and negotiated an Equitable Adjustment settlement, in the Lump Sum amount of $230,607.48. CONTRACT TIME: Thirty (30)additional working days are being added to the Contract Time as a result of the Changed Conditions of encountering of soft,moist soils while installing sanitary and storm sewer pipe in the first two blocks in Colby between 37'h and 39''streets, and stumps,logs and peat soils in the intersections of 39th&40th streets of Colby Avenue.
