Location: Tacoma

Contractor: Joseph J. Jefferson & Son

Architect: Helix Design Group

Team: Evergreen Building Products, Sto Corp.



This building is a three-story medical facility with space for outpatient care and day surgeries. It was a phased remodel project.

The new facade is 15,000 square feet of moisture drainage EIFS installed over a sprayed-on waterproof air-barrier — Sto Therm Lotusan NExT 100G. An R-value of 21 was attained with 5-inch-thick continuous insulation, and the finish was Sto Lotusan with integral color applied over mesh and the base coat.

One of the greatest challenges of the project was that the work had be scheduled and coordinated around a functioning medical facility. The schedule duration was only three months. Work included daily removal of selected windows and installation of weatherproofing, new windows, flashings and the EIFS.

Other challenges included installation of expansion joints through the 5-inch-thick foam, restricted access, and limited site area for scaffold erection and material storage.

Judge’s comment: “This exterior cladding is the perfect example of how a well-installed system can enhance the beauty of a building. The design and construction team can be proud of what they constructed on this project.”
