King County Housing Authority Greenbridge Division 8 Phase 1 and Park

KPFF designed and provided Construction Management services for Phase 1 of King County Housing Authority’s Greenbridge Division 8 Project, which constructed utility and road improvements in West Seattle along 4th Avenue, SW 102nd Street, and 5th Avenue. Construction included installation of a large 50’ detention vault, new sidewalks and asphalt paving, and extensive utility installation including storm, sanitary, gas, and power. Work also included the development of a large park at the entry to Greenbridge, which serves as the main entryway landmark for the overall community. Prior to construction, KPFF’s CM Team worked with the owner and engineers during planning and design. Development of the project manual was complex and required a high level of attention to detail since the entire Greenbridge development was permitted as a single project, and had to be subsequently split into multiple construction phases – a process which was facilitated by KPFF’s CM Team. During construction, KPFF developed independent estimates, negotiated changes and compiled change order documentation, responded to and coordinated with appropriate parties on RFIs and submittals, facilitated weekly construction progress meetings, coordinated with Authorities Having Jurisdiction (AHJs), observed construction on site and provided daily field reports, scheduled special inspections and testing, and utilized a web-based project management tool for documentation. Schedule was extremely important on this project as the next phase was planned to be constructed by a different contractor, which required swift and efficient coordination efforts when unforeseen and complex utility conflicts arose that affected a water main the entire length of 5th Avenue. KPFF’s CM Team resolved the issue by coordinating in-house with the KPFF design team to determine two options to move forward, then coordinating externally with the contractor, AHJs, and KCHA representatives to quickly make a decision and keep the project moving. This project also experienced adverse weather conditions, delaying the substantial completion date. KPFF worked with KCHA and the contractor on a day-to-day basis to perform the work as the weather allowed and utilized schedule acceleration tools to get the project schedule back on track. Upon project completion KPFF facilitated AHJ inspection and project closeout.
