Mercer Island House

Project overview

The Mercer Island project, originally constructed in 1957 and renovated in 1981, involved a forensics analysis of a 3-level, 5,880 square foot single-family residence located on Mercer Island, Seattle. Positioned lakefront, the property’s large picture-frame windows and doors were subjected to severe weather conditions, resulting in significant water infiltration issues.

The scope of work included a detailed investigation of water infiltration affecting various building systems, including the windows, doors, and siding. Following this investigation, existing windows, doors, and siding were removed and replaced with new, more durable systems to address the water infiltration problem.

After completing the investigation phase, a comprehensive scope of work and full design package were developed for all impacted building systems, allowing for the establishment of Rough Order of Magnitude (ROM) pricing. The next phase included the development of complete construction documents and specifications, a competitive bidding process, obtaining building permits, and overseeing the entire remediation process.

Key contributions included building investigation and forensics, as-built documentation, construction documentation, specification development, bid management, permitting, and construction administration.
