PRESENTATIONS II. BUSINESS AGENDA There was consensus to take up items C and D as the first items of business. A. Change Order: Andover Park West to Andover Park East Sewer Repair Project Staff is seeking Council approval of Change Order No. 3 with the R.L. Alia Company for the Andover Park West (APW) to Andover Park East (APE) Sewer Repair Project in the amount of $91,152.15. The original contract was awarded in September 2014 for the repair of a collapsed sewer line between APW and APE and the installation of a manhole in APE near Strander Boulevard. Following successful completion of the repair work a second collapsed portion was discovered. Alia exposed and successfully repaired the second collapse, and subsequently the entire line has been sliplined under a separate contract with Michels Corporation. This Change Order covers the cost of the second, unanticipated collapse and repair. Funds not covered by contingency are available from the 2015 construction funds of the Central Business District Sewer Rehabilitation Project. UNANIMOUS APPROVAL. FORWARD TO MAY 18, 2015 REGULAR CONSENT AGENDA. B. Proiect Completion: Central Business District Sanitary Sewer Rehabilitation Staff is seeking Council approval of project completion and release of retainage to the Michels Corporation in the amount of $171,530.07 for the Central Business District Sanitary Sewer Rehabilitation Project. The Michels Corporation relined 2,444 feet of sanitary sewer pipe. Photos and video of the project were displayed for the Committee. Committee Chair Robertson requested a future committee discussion on strategies to accommodate new types of development in the Urban Center. UNANIMOUS APPROVAL. FORWARD TO MAY 18, 2015 REGULAR CONSENT AGENDA. C. Grant Amendment: Duwamish Gardens Project Staff is seeking Council approval of a grant amendment for additional construction funding for the Duwamish Gardens Project in the amount of $250,000. The Duwamish Gardens Project's design and permitting are complete and construction is expected to begin this spring. In 2014 the City accepted $949,434.00 in grant funding from the Washington State Recreation and Conservation Office (RCO) for the construction. Review of the project budget prior to bidding revealed a shortfall in funding. Staff contacted RCO and secured the additional $250,000 proposed in this grant amendment. With this increased funding level the City's required match would then become $381,523.00, and funds for the match are available from other non -RCO grant funding, including King County Conservation Futures, King Conservation District, and the King County Flood Control District. UNANIMOUS APPROVAL. FORWARD TO MAY 18, 2015 REGULAR CONSENT AGENDA. 129
