Western Wood Structures Western Wood Structures, Inc. The Top Mass Timber Erectors in the Northwest

Western Wood Structures has been in the living up to its name since 1969.

Working Wonders With Wood: Specializing in Design, Engineering, Supply, Installation, and upgrades of any heavy timber project, including Mass Timber, CLT, Sound Stages, Bridges, Shelters and Truss & Beam Projects. Decades before Mass Timber became a buzzword, Western Wood Structures has been designing, supplying and erecting some of the most iconic timber structures in the world. From the 530 ft.

diameter Tacoma Dome in Tacoma, Washington to the 475 foot Cable Stayed Suspension Hiroshima Airport Bridge WWSI has been widely known for innovative designs and methods of erecting Heavy Timber and now Mass Timber structures. Founded in 1969 by a team of timber sales and engineering experts, WWSI has been a leader in the design and construction of timber structures including domes, bridges and other large timber structures. The original partners all traced their experience and training back to Timber Structures which was at the time the pre-eminent engineered timber supplier from 1940 through the 1960s. The WWSI team leveraged their experience and a can-do attitude to stay the industry leader for the next 50 years. Today WWSI’s sales team is supported by engineering, fabricating and jobsite installation teams. Whether you need an iconic structure like the Cathedral of Christ the Light in Oakland or a massive foot bridge to span a glacier fed river, WWSI can provide the design, means and methods to accomplish your goals.
10 reasons to consider working with Western Wood Structures, Inc.

1. Western Wood Structures team of sales, engineering and field services have designed and installed more than 5,000 bridges throughout the United States and overseas.

2. In house engineers keep consulting costs low. Our engineers focus on design of wood structures and serve on the national code writing committees to keep current.

3. We use the latest computer design and 3D modeling software to design and detail the most efficient systems. The use of this software allows us to quickly optimize any system and review options.

4. Due to our experience with a wide variety of structures, our sales staff, supported by the engineering and field services, can quickly develop budget pricing for most any job.

5. We are able to custom design most any structure.

6. Using skilled craftsmen and now CNC fabrication software, we can accurately prefabricate trusses, beams, columns, and bridge members, allowing quick, efficient onsite assembly and erection.

7. Our timber projects arrive on site as complete packages including the steel connecting assemblies and connecting hardware. Field fabrication is kept to a minimum.

8. Our experienced construction crews have a deep understanding of the timber erection process and can find site issues long before the materials are made so the issues can be addressed before the materials arrive on the jobsite.

9. Our field engineering staff has years of experience developing rigging, crane plans, shoring and temporary structures needed to safely erect mass timber components.

10. WWSI has maintained relationships with more than 6 laminators, 4 steel fabricators, 4 hardware suppliers and 6 sawn lumber suppliers, each with their own strengths. These relationships allow us to put the best team together for the project.

Keystone Wye Bridge | South Dakota

This bridge was originally designed by WWS, way back in 1959, when we were still called ‘Timber Structures’.

60 years later, in 2021, the original timber support columns and timber arches were still in excellent condition. The concrete deck panels were in need of replacement, and new glulam timber panels and an updated rail-and-curb system were recommended.

WWS designed the new panels, supplied and pre-fabricated the panels and rail system, and shipped all materials in a sequenced order to the jobsite.

A look back at construction for a project in Santa Monica, where Western Wood Structures designed, supplied, and installed the timber components for a multi-building office campus using Cross-Laminated Timber and Glulam.

The project includes three separate buildings, each four stories high, with roughly 16,000 square meters of building area. During construction, the exposed CLT panels and glulam members showed exactly why mass timber continues to stand out: warmth, strength, efficiency, and a visual presence that changes the feel of the entire space.

Placer River Trail Bridge | Anchorage, Alaska

At 85 meters, this is the longest clear-span timber truss bridge in North America. Located just downriver from the massive Spencer Glacier in Southern Alaska, it was essential that we accounted for the estimated snow load of 300 psf, which is heavier than a typical bridge’s vehicle load. The ambitious length and heavy snow load made this project an exciting undertaking for WWS.

We designed, fabricated, and shipped the project to the jobsite. A local contractor installed the bridge, with the help of a WWS jobsite consultant.

Gerry Frank Salem Rotary Amphitheater | Salem, OR

This mesmerizing pattern of crossed timber beams was designed to look like a basket woven by the Kalapuya people, the original inhabitants of Salem. WWS constructed the canopy in 2021 using laminated Alaskan Yellow Cedar timber.

Pre’s Trail Bridge | Eugene, OR

In the shadow of Autzen Stadium, tucked inside Alton Baker Park, sits the Pre’s Trail Bridge—a busy crossing over the Canoe Canal just south of the stadium. On any given day (and especially during Duck football games), this pedestrian bridge sees a steady stream of fans and parkgoers.

The bridge needed a refresh, and WWS was glad to step in. Along with much-needed repairs, the bridge is getting a slight increase in width, making game-day crossings smoother for everyone.

The classic Northwest timber look isn’t going anywhere. WWS preserved the bridge’s character while upgrading it with new glulam deck panels and a refreshed rail system.

Work will wrap up in the coming weeks, so stay tuned for photos and updates. And keep an eye out—we’ve got another, slightly bigger project near Autzen Stadium in the works. 👀

Construction Shots from The Cathedral of Christ the Light | Oakland, CA

Completed in 2008, this cathedral replaced an older structure, which was irreparably damaged in the 1989 Loma Prieta earthquake. The new structure brought together glulam, glass, steel rods, and seismic engineering to create a contemporary house of worship designed for both beauty and resilience.
Western Wood Structures supplied the glulam for the project and developed a tightening sequence to eliminate force interference between rods, helping ensure forces were correctly distributed throughout the structural skeleton.

Nanlin Temple (Part II) | Taiwan

Taken during the temple’s construction in 2009, this photo shows our jobsite consultant standing alongside a Buddhist nun who called the Nanlin Nunnery home. The temple, designed, supplied, and delivered by WWS, is part of a larger complex of structures that comprise the nunnery, a peaceful refuge for Buddhist monastic life.

Mass timber was the perfect material, aligning seamlessly with traditional Taiwanese temple architecture and the surrounding buildings.
