The Sideyard Project- Innovative & Sustainable

2020-10-07T13:11:10-07:00October 7th, 2020|

The Sideyard project in Portland Oregon was recognized by Archidust, as a strengthening connection between the Eastside community and the westside downtown urban core. This unique 9,000 sf space was created when the City of Portland built a new one-way street which reconnected the roadway to the Burnside bridge. The building was designed to fit on a unique urban property as a working-class building, targeting public transportation connectivity. The small lot and busy urban traffic, created a more challenging design and construction. DRJ Cross-Laminated Timber and Glu-lam beams served as the buildings main structural components.

The Construction Benefits of CLT

2020-09-28T15:54:40-07:00September 28th, 2020|

There are many construction benefits to Mass Timber Buildings: Mass Timber buildings can be up to 30% lighter than steel and concrete structures. With mass timber buildings, comes smaller foundation requirements and lower forces for seismic resistance. Buildings built with mass timber can be erected up to 25% faster with less waste and job site traffic than steel or concrete buildings. Cross-Laminated Timber and Glu-Laminated Timber building are fire safe with 2-hour or greater fire ratings! Wood members can be used to protect steel components and connectors, increasing fire safety. The strength of wood members see less decline when exposed to fire than steel, and failure of a member is

Mass Timber Sustainability

2020-09-23T14:26:34-07:00September 23rd, 2020|

Mass Timber materials are safe, sustainable, efficient, and an innovative method of construction. Wood is the only major construction material that is renewable, sustainable, and creates a net positive effect on the environment. By utilizing Mass Timber, wood industries promote sustainable forest management and harvesting practices. Through the Oregon Forest Practices Act, Oregon has strong laws and policies in place to promote healthy and growing forests. The Oregon FPA sets policies including limits on clear cutting practices, protection of streams and water resources, and requires harvested areas to be replants within two-years of a timber harvest. These policies help ensure that Oregon Mass Timber products remain sustainable and contribute to

How is Cross-Laminated Timber Manufactured?

2020-09-11T10:55:49-07:00September 11th, 2020|

How is Cross-laminated Timber Manufactured?   Cross-Laminated Timber is created by stacking lumber in alternating directions, and being pressed together with strong adhesives to form a strong panel. These panels can be formed into 3-ply, 5-ply, or 7-ply, depending on the project's needs.    The details of cross-laminated timber manufacturing vary from manufacturer to manufacturer but generally follow the process below.     Lumber is selected for use within the CLT panel. The lumber is visually or mechanically graded and moisture content is checked. Moisture content must be 12% +/- 3%     Group lumber by grade     Plane lumber to appropriate thickness     Finger-joint and cut individual

The Mass Timber Movement

2020-09-04T11:24:13-07:00September 4th, 2020|

As the First Certified Manufacturer of Cross-Laminated Timber in the United States, we are very proud to be apart of the Mass Timber Movement! Cross-Laminated Timber was first developed in Australia in the early 1900's, designed to create a more sustainable form of construction for residential construction. DR Johnson started producing Cross-Laminated Timber in 2015, and now, CLT is the most familiar and widely-used Mass Timber product in the U.S. In order for a construction project to be classified as a "Mass Timber Project," the load-bearing structure would be constructed with the use of Mass Timber. Most applications that use Cross-Laminated Timber are office buildings, hotels, multi-use buildings, public &

The Creative Mass Timber Office

2020-09-01T16:13:17-07:00September 1st, 2020|

District Office is a large mass timber project designed by Hacker Architects, to create a fresh & flexible retail, office, and restaurant space in downtown Portland. The 90,000 sf, six-story building, is known for it's exposed mass timber that consists of DR Johnson cross-laminated timber (CLT) and glu-laminated beams/columns. The CLT panels throughout the structure consisted of 3-ply panels, and the glulam spans ranged form 30 to 40 feet. One of the main objectives architecturally, was to fully expose the wood structure. This required strategical design thinking to ensure that the building's design was aesthetically thoughtful, as well as structurally sound. As the demand for mass timber grows and expands
