During preconstruction, the team saved nearly $1 million by changing the building massing to take advantage of the site’s natural grade. Because the structure is on a hill, rather than building up for a third floor, the team excavated slightly more to create an additional floor below. The main entry presents as a single level building, creating a more inviting entrance. The building would have been 15 to 20 ft higher, which also would have obstructed views for nearby buildings.

Locally sourced mass plywood and low-carbon concrete contributed toward the facility’s LEED Gold certification. Crews also ensured 61% construction waste diversion. Native and indigenous plants selected with Cowlitz tribe members ensure cultural representation.

Fully automated greenhouses feature ridge vents, sun shades, evaporative cooling, grow lamps and VRF systems monitoring atmospheric conditions for plant and butterfly research—all realized with the help of a specialty national greenhouse contractor. Meanwhile, the vivarium uses dedicated outside air and negative pressurization to maintain environmental control and ensure safety for research animals and personnel. The team brought on third-party commissioning agents to ensure these complex systems all functioned as necessary.

For the exterior wall assembly, the team chose to use mass plywood panels, which are similar to tilt-up panels with a pre-installed weather resistant barrier and precut window openings. All exterior mass plywood panels were installed in just two weeks, resulting in notable schedule savings—with the project completing several days faster than anticipated.
