It was a balancing act, according to the project team.

That is, when facing a decision of whether to keep a portion of Twality Middle School in Tigard and add to it, or simply demolish the entire existing facility and construct a new one, officials opted for the former. Existing concrete shell structures will be kept and renovated, and eventually connect with a new, two-story building.

“It’s almost a new building,” said Shawn Christensen, a project manager with Day CPM, the owner’s representative for Tigard-Tualatin School District. “We kept 27,000 square feet worth of the concrete boxes in the gym, which is going to stay a gym. There’s another gym that we’re converting to locker rooms. And then we’ve kept the cafeteria, and we are converting that to music rooms. Everything else got torn down.”

IBI Group designed the $46 million project, and Woodburn-based Triplett Wellman Contractors is serving as general contractor. The school will gain a new gymnasium, media center, common areas, visual arts classrooms, maker space, centralized administrative offices and a full suite of wired-for-technology classrooms.

All of it is spread over two stories, with the ground floor nestled into a hillside. This will give the impression of a daylit basement and provide convenient access across both floors.

The school’s orientation will be roughly north to south, with the existing structures situated at the site’s south end. Construction is being split into two phases; currently, the first phase is under way at the site’s north end.

“The big push right now is just the framing,” said Greg Yoder, site superintendent for Triplett Wellman Contractors. “The site contractor was here today – it’s Catworks out of Vancouver (Washington), and they’re doing all the dirt work. And then we’ve got (PDX) Electric doing our electric, and Hydro-Temp is our plumber. And they’ve got both the wet and the dry side, so plumbers have been working getting the slab-on-grade stuff in.”

The building will have slab-on-grade foundations with wood framing and glulam columns and beams for structural support over the typical long spans found in schools. A curtainwall system will bring let natural light into the building from the west side, where new parking and bus pathways will be built. Both levels of the new building’s east side will feature vertically accented metal panels and glazing.

The project is part of a two-pronged remodel of a campus that also includes Templeton Elementary School. The latter was rebuilt in a similar fashion, with a portion of the 1960s-era building retained. That project was completed this past summer, and students and staff are now using the new space.

The project team decided to take a similar approach with the Twality project, though it remains uncertain whether it’s the most cost-effective one.

“We kept the (old) gym operational during construction, so it’s been a significant challenge to keep that gym free of noise and issues,” Christensen said. “They were thinking there would be budget savings with these giant concrete boxes, but as far as we’ve gotten into the building I’m thinking we might not have saved money by keeping the boxes.”

But the move allowed officials burdened by construction at both schools to maintain gym space.

“There were definitely complications associated with that for sure,” Christensen added. “And honestly they needed the gym. They only have a small gym down there at the elementary school, so using this gym has allowed them to run PE (classes) for 1,100 students.”

Similar choices were made with the old school cafeteria, which will tie in with the new building.

“It will all be connected,” Christensen said.
