Resulting from one of the largest bonds passed in Oregon’s history, Beaverton’s 334,000-square-foot Mountainside High School is the largest comprehensive high school in the state. Set on 47 acres, the school serves 2,200 students in a 鈥渓oop stacking鈥� program that houses nearly all formal and informal academic spaces.

Open-concept teacher planning and circulation from the loop’s interior allow light to spill through these areas and into the classrooms, which also benefit from natural daylight due to their position along the exterior wall. Key program pieces including the gym, theater and commons are located close to the front door, easing access to high-traffic areas and streamlining wayfinding for students and visitors.

Wood salvaged from two onsite barns that were demolished clads a central stair and the walls of the theater lobby. A second-story media center overlooks both the commons and the courtyard, and the courtyard features outdoor classroom spaces.

Mountainside also provides robust Career Technical Education components, including a culinary kitchen/classroom; robotics space; and a 3,500-square-foot, state-of-the-art woodshop. The school’s fully ducted, dust-collection system is installed with a wood-pellet maker, allowing students to sell the byproduct as a fundraiser.

Chris Linn, a principal with Bora Architects, said the school’s advanced technology sets it apart, as does its dual role as a community emergency shelter because of its ability to withstand a higher magnitude earthquake than a typical school.

鈥淭he brick fa莽ade is particularly unique. The pattern transitions in color from top to bottom and was designed using parametric software 鈥� a first for us and for the brick masons,鈥� Linn said.

Along with some bad weather conditions and an already-tight schedule, challenges included the site’s sloped topography. A large volume of predominately clay soil needed to be moved and reused as fill. By expediting mass excavation and identifying opportunities to reuse soils from the site, the project team avoided routing hundreds of dump-truck loads through the community. In addition, unforeseen conditions that arose during excavation required Hoffman Construction as general contractor and Bora to collaborate with city staff to implement a design change to the storm drainage and sewer systems.

Mountainside’s multiple athletic fields required 10.5 acres of turf, making it the largest high school turf-installation project in the Pacific Northwest. And its auditorium was built with a 鈥渟hip in a bottle鈥� construction approach that reversed some typical sequences and utilized Building Information Modeling.

鈥淲e re-learned a key lesson 鈥� that it takes a very high level of teamwork between the owner, the general contractor and the architect to successfully complete large, complex projects,鈥� Linn said, noting staff with the Beaverton School District were 鈥渃onsummate professionals鈥� and Hoffman’s 鈥渄edication to doing the work well and doing it right the first time was something to behold.鈥�
