City of Tukwila <br />Allan Ekberg, Mayor <br />INFORMATIONAL MEMORANDUM <br />TO: Transportation and Infrastructure Committee <br />FROM: Bob Giberson, Public Works Director <br />BY: Cyndy Knighton, Senior Program Manager <br />CC: Mayor Ekberg <br />DATE: July 21, 2017 <br />SUBJECT: Baker Boulevard Non - Motorized Improvements <br />Project No. 91610409, Contract No. 07 -123 <br />Supplemental Agreement No. 17 <br />ISSUE <br />Approve Supplemental Agreement No. 17 with KPFF for construction management support and inspection <br />services for the Baker Boulevard Non - Motorized Improvement Project. <br />BACKGROUND <br />KPFF has completed the design of the TUC Pedestrian /Bicycle Bridge Project (Ped Bridge) and the Baker <br />Boulevard Non - Motorized Improvements Project (Baker). The Ped Bridge construction is well underway and <br />KPFF provides design support for that work. The Baker project bid opening was June 20, 2017 with Road <br />Construction Northwest (RCNW) as the low bidder. The contract was awarded to RCNW at the July 17, 2017 <br />Regular Meeting. The Baker project must be completed within 80 working days and all impacts that would <br />result in lane closures must be completed prior to the November 17, 2017 holiday moratorium. This results <br />in the contractor needing to be able to start construction no later than July 28, 2017. Due to the compressed <br />timeline for construction, staff determined that a supplemental contract to KPFF for the construction <br />management support and inspection services was the best course of action. <br />DISCUSSION <br />City staff will be providing most of the day -to -day management and engineering support for the construction <br />management. KPFF will provide the inspection services and document control with limited engineering <br />support for construction management. KPFF will be on -call for any design support necessary as the <br />construction progresses. Supplemental Agreement No. 17 to KPFF's Contract 07 -123 was negotiated as <br />the most cost effective and expeditious way to have the construction management support and inspection <br />services on Baker Boulevard and incorporated with the design work already completed for the Green River <br />Trail and Christensen Road. <br />FINANCIAL IMPACT <br />KPFF's Supplemental Agreement No. 17 for the Baker Boulevard Non - Motorized construction management <br />support and inspection services is $119,680.98. There is $120,000 budgeted in the Baker Boulevard <br />Project for construction management. <br />RECOMMENDATION <br />Council is being asked to approve Supplemental Agreement No. 17 with KPFF for the Baker Boulevard <br />Non - Motorized Improvement Project in the amount of $119,680.98 for construction management services <br />and consider this item on the Consent Agenda at the August 7, 2017 Regular meeting. <br />Attachments: Page 15, 2017 CIP <br />KPFF Supplemental Agreement No. 17 <br />wApw eng \projects\a- rw & rs projects \baker blvd non - motorized ( 91610409) \construction \construction management \information memo - kpff supp #17 cm 7- 21- 17.docx 5 <br />
