Boardwalk

Boardwalk is a LEED Platinum, seven-story mixed-use luxury apartment building in the heart of Kirkland. The fully air-conditioned, 171-unit complex has rooftop views of Lake Washington and the Olympic Mountains. It offers the local community generous outdoor public spaces and landscaping as well as easy access to PCC Natural Markets grocery store on the ground floor. Boardwalk’s private courtyard provides a quiet, lush space with integrated stone seating. High quality cladding finishes, including brick, precast concrete, stone, glass, Equitone panels and metal siding, create a striking low-maintenance exterior.

W.G. Clark’s expertise was needed to ensure successful shared site access with Google’s adjacent 7-story office development. In addition to replacing the entire access road, every major utility for both buildings was upgraded or replaced while concurrently coordinating the flow of thousands of deliveries in and out of the two sites. Shared utility trenches that were as deep as 12 feet, created several safety and logistical challenges that were successfully solved by W.G. Clark.

The project scope included supporting the weight of an adjacent five-story concrete office building. Boardwalk’s east shoring wall was installed without removing the neighbor’s existing retaining wall. A carefully coordinated sequence of removing segments of existing footings, installing new shoring piles, and finally connecting them to the existing retaining wall minimized project costs and avoided inconvenience to the neighbor.

W.G. Clark also lead construction coordination between the shell and core and grocery buildout. This included the addition of tenant-specific structural upgrades, specialized refrigeration systems and commercial cooking systems. The structural concrete floor of the tenant space required 25 precisely located floor block outs and 350 pipe sleeves to accommodate the grocer’s mechanical, plumbing and electrical requirements. This coordination effort also extended through the building to the roof. For example, one quadrant of the roof framing was redesigned to accommodate the weight of the cooling tower and associated 14-foot tall screening system, all without extending the overall project schedule.
