2019 - 2021

KBA provided construction management services in the BelRed area for the $13 million, quarter-mile first phase of widening 124th Avenue NE from NE Spring Boulevard to NE Ichigo Way. With a nine-month road closure to thru traffic, significant coordination with utilities, businesses, adjacent projects, and the public was required to keep business access open while progressing on contract work. The concurrent Sound Transit East Link work at the bridge site resulted in changing site conditions. KBA managed the multiple changes by cultivating great relationships with the contractor, design engineer, and the City of Bellevue.

Client: City of Maple Valley
Location: Maple Valley, Washington
2019 - 2020

​KBA provided full CM services for the City of Maple Valley's $4.8 million street widening project. The most notable feature of this project was the use of a soldier pile wall, which permitted the addition of a commuter lane, bike lane, and sidewalk. A comprehensive drainage system was installed, as well as a state-of-the-art infiltration system. During KBA's initial review of the project, it was determined a few items the designer incorporated into the project were not actually needed based on KBA's knowledge of the area's geological make-up. By eliminating these items (structural soil and pedestrian handrail), we were able to reallocate resources to renovating an entire intersection that was not in the original design. The resulting changes and upgrades were completed within the original timeframe.

Client: City of Issaquah
Location: Issaquah, Washington
2017 - 2019

​KBA provided full construction management services for the extension of SE 62nd Street from East Lake Sammamish Parkway to Lake Drive. The project constructed a connecting roadway and two roundabouts, a multi-use trail connection, and sidewalks. Significant coordination with utilities, businesses, and the public was required to keep business access open. Before construction began, the contractor proposed to re-design the bridge with 36” diameter pipe piles, 70’ and 90’ long. When bearing resistance was not achieved as expected, KBA coordinated with the Geotech, general contractor, designer, and client to revise the plans and solve the issue in real time. KBA established great relationships with all stakeholders, allowing better communication and collaboration to coordinate real time resolutions to conflicting project demands.
