Building a 138-megawatt Data Center Campus in Hillsboro, Oregon
In a few short years, we’ve built our Data Centers & Advanced Technology Group (DCAT) from the ground up.
This includes delivering a 138-megawatt data center campus in Hillsboro, Oregon.
In the video above, hear from Lewis director of operations Mike Sager about the unique challenges of retrofitting an existing building and constructing two new ground-up data centers on a constrained 45.5-acre site adjacent to an airport.
Mike also shares how Lewis uses rigorous controls to anticipate procurement challenges, prevent equipment quality issues, and streamline delivery and execution in the field.

Expanding Career and Technical Education on the Oregon Coast
With interest in career and technical education (CTE) programs surging, Oregon Coast Community College is building on its longstanding role in local workforce development to meet the moment.
In early 2026, construction will be ramping up on the college’s Oregon Coast Advanced Technology & Trades (OCATT) Center in Newport.
Envisioned as a hub for hands-on learning and workforce development, OCATT will open new pathways for Lincoln County residents to train, work, and build lasting careers close to home.
When complete in 2027, the 22,000-square-foot facility will provide hands-on training in construction and carpentry, industrial facilities maintenance, maritime technology, HVAC systems, and welding, as well as pre-apprenticeship offerings.
A learning environment without silos
The Center has been designed to reflect the cross-disciplinary nature of today’s industries and trades. Rather than assigning spaces to fixed programs, the building is organized around skill sets.
“From the beginning, the college wanted a space that was incredibly flexible,” said Tyler Whitehead, partner at BNDRY Studio and the project’s CTE consultant.
The architect of record, GLAS Architects, along with design architect Hacker Architects and BNDRY, developed a concept focused on four primary labs: building systems, mechanical systems, electronic systems, and a “dirty build” lab for metalwork, welding, and diesel engines. Complementing them is a flexible learning wing.
“Nothing in the real world happens in silos,” says Christopher Walkup, a principal at GLAS. “We wanted to replicate that sense of collaboration and crossover. You might learn how to use a skill saw in one space, then apply those same safety and problem-solving skills in another.”
That flexibility extends far beyond layout. The building is being designed to evolve as industries and community needs change. That might mean reconfiguring them to host new equipment, supporting new certifications, or aligning with emerging technologies like automation.
“It’s about teaching students how to learn,” Whitehead said. “The programs can shift quickly based on what the community needs, because the building itself is built to respond.”

Foreman Feature: Lorie Tibbetts
If you’ve ever admired a large-scale Lewis commercial project in Seattle, there’s a good chance general foreman Lorie Tibbetts helped build it.
Over her career, Lorie and her crews have placed more than 560,000 cubic yards of concrete. That’s 2.2 billion pounds of material.
Her journey with Lewis began back in 1990. She was 22 when a friend suggested she ask a superintendent for a spot on the Second & Seneca tower project. Before long, she found herself helping with a concrete pour, rake in hand.
That opportunity launched a career defined by both technical expertise and the ability to build strong, close-knit crews. Ranging from six to eight people, Lorie’s teams move together from job to job and handle everything from building structures, to flagging, to final cleaning.
