CONTRACT: CAG-17-075 PROJECT: N 27TH PLACE BRIDGE SCOUR REPAIR SUPPLEMENT DESCRIPTION During the course of construction, working days were added to the construction contract for removal of sheet pile obstructions and other changes. The ariginal contract scope and budget was based on the original number of working days in the construction contract. To provide services for the working days added to the construction contract, additional budget for Construction Administration and Inspection (CA&I) services is necessary. The International Union of Operating Engineers (IUOE)loca1302 had a labor dispute with the Associated General Contractors (AGC) of Washington. IUOE 302 went on strike on August 21, 2018 and went back to work on September 7, 2018. This delayed the reopening of N 27th Place by several weeks. In order to reopen the street as quickly as possible after the labor dispute ended, the contractor worked extended week day warking hours and weekends. To provide inspection services during the extended work hours, additional budget for CA&I services is necessary. During sheet pile installation, driving conditions prevented the installation of Wall 2 per the construction contract. As a result,Wa112 was deleted from the construction contract and the design of the scour repairs was revised accordingly. To provide for the revised design of the scour repairs, additional budget for Design Construction Support Services (DCSS)is necessary. TASK 1.0 CONSTRUCTION ADMINISTRATION AND INSPECTION (CA&I) SERVICES Task 1.2 Construction Administration and Inspection No change to the original scope of work for this task.The purpose of this supplement is to provide additional budget for the scope of this task, for the reasons stated above. Refer to E�chibit D-1 for an estimate of the budget required to provide CA&I services for the working days added to the construction contract and extended working hours.
