The select fill problem was resolved with the issuance of Change Order No. 2, but the contract time was not addressed. Dickerson estimates that they were delayed in excess of 120 days. Their contract schedule indicated this resulted in a schedule delay of 100 days. Dickerson believes that they can make up for approximately 35 days and have therefore requested a 65 day extension. This moves their contract completion date from September 19, 1999 to November 30, 1999. Staff recommends approval of the attached Change Order No. 3 which reduces the contract in the amount of (44,512.57). This subtracted from the current contract amount of $6,189,457.70, results in a new contract amount of $6,184,945.13.
