BACKGROUND In February 2006, IBI Group was retained by the City to begin design of the Tukwila Urban Center Transit Center on Andover Park W. A Comprehensive Plan update was adopted by Council in late 2007 that included language regarding the Transit Center siting options. Since then, staff began negotiations with the IBI Group for design of Phase I (west side only) of the Transit Center. ANALYSIS The intent of the original contract was to have the Concept Plan done quickly, a siting decision made by Council, and final design of the new Transit Center underway. Supplements #1 -3 were issued to extend the contract time to June 30, 2008 to accommodate for project delays. Negotiations on scope and fee for the next step took longer than anticipated. The attached Supplement #4 will complete at least 30% design of the improved and expanded Transit Center in its existing location on the Westfield Southcenter Mall property. Final design, additional geotechnical investigation, cost estimating, bidding assistance and on -call assistance during construction are all listed as optional tasks to allow for future supplemental agreements. Easements are being dedicated to Tukwila as part of the ongoing Binding Site Improvement Plan as per the Development Agreement. The original contract amount was $199,489.00 and with Supplement #4 at $153,754.00, the new contract amount will be $353,243.00. The project currently has $400,000.00 budgeted on page 46 of the 2008 CIP. RECOMMENDATION Approve the Supplemental Agreement #4 to Consultant Agreement #06 -019 in the amount of $153,754.
