ORB Architects, now part of INNOVA Architects, was chosen by Seattle Parks & Recreation to perform a condition assessment of the Colman Pool, Seattle's only outdoor saltwater pool in Lincoln Park in West Seattle. The assessment of the pool determined the extent of upgrades needed. ORB provided cost estimating, design, and construction administration services for the pool's improvements.

The project essentially involved the rebuilding of the pool shell, utility tunnel, gutter, and perimeter deck. Due to the historical nature of the 1941 Olympic size pool and the salt water content of the pool, a very unique approach as well as many custom details had to be implemented. This included water stops between new and old, crack repairs, specific sequencing of the concrete pours, and cathodic protection.

ORB's in depth knowledge of pool systems and structure was vital to the success of the construction of the structural and mechanical upgrades. The renovated Colman Pool re-opened on schedule on June 30, 2012.
