Silicon Valley design-build firm Katerra is using a technology-driven and full-services approach to creating prefabricated structures at a large scale. Based in Menlo Park, California, Katerra was started in 2015 by Michael Marks, Jim Davidson and Fritz H Wolff. Combined, the three men have decades of experience in the technology, manufacturing, real estate and private equity industries. In 2007, Marks served as the interim CEO at Tesla.
The design-build startup – which describes itself as a technology company – has about 60 architects on staff, along with 10 interior designers. The team is led by architect Craig Curtis, who formerly was a partner at The Miller Hull Partnership, a prominent Seattle firm.
Katerra’s overarching mission is to streamline the design and construction process while still providing good architecture. “Our goal is to remove unnecessary time and costs from the building process while also providing world-class design,” said the firm, which is one of the investors in Architizer’s online marketplace for architectural products.
Katerra believes it stands apart from other design-build firms because of its focus on utilizing technology and modular components to create large-scale multifamily, commercial and institutional projects. It also handles all steps of the building process, including site development, schematic design, fabrication of parts and onsite construction. “Through curating our own high-quality supply chain we can provide a fully coordinated design, much like what you would expect when buying a car,” the firm said. “By working within one fully integrated service model, clients no longer need to depend on multiple partners and vendors.”
The firm generally uses wood frame construction, with several upcoming projects featuring cross-laminated timber (CLT). “Katerra is aggressively pursuing CLT, with plans to help North America start using the material on scale with Europe,” the company stated.

The International Code Council Ad-hoc Committee on Tall Wood Buildings provided five fire scenarios that were tested in each of the two one-bedroom apartments constructed using mass timber in a multi-story apartment building. The test scenarios included various arrangements of exposed and unexposed cross-laminated timber (CLT) with open doors between living and sleeping areas while the effectiveness of automatic sprinkler systems was simultaneously evaluated.
Test 1: a mass timber structure fully protected with gypsum wall board was subjected to a large furnishings and contents fire. The test was terminated after three hours without significant charring on the protected wood surfaces of the structure.
Test 2: approximately 30 percent of the CLT ceiling area in the living room and bedroom were left exposed. The test was terminated after four hours, providing additional time to determine if there would be any significant fire contribution from the exposed CLT. Notably, once the furnishings and contents had been consumed by the fire, the exposed CLT essentially self-extinguished due to the formation of char that protected the underlying wood.
Test 3: parallel CLT walls were left exposed, one in the living room and one in the bedroom. Similar to Test 2, once the apartment furnishings and contents had been consumed by the fire, during which a protective surface of char formed on the CLT, the mass timber surfaces essentially self-extinguished.
Test 4 and 5: examined the effects of sprinkler protection. For both tests, all mass timber surfaces in the living room and bedroom were left exposed. Test 4 demonstrated that under normal operating conditions, a single sprinkler easily contained the fire. For Test 5, the fire was allowed to grow in the compartment for 23 minutes before water was supplied to the sprinklers which quickly controlled the fire.

A two-story cross-laminated timber (CLT) structure is being subjected to the forces produced by a 1994 6.7 Northridge earthquake. The engineered simulation is expected to reveal ways in which tall wood buildings could survive damaging earthquakes.
Workers constructed a 22-foot tall wood test structure on UC San Diego’s shake table, a device for shaking structural models or building components with a wide range of simulated ground motions, like earthquakes.
Led by the Colorado School of Mines (CSM), the new test will examine the viability of constructing quake-resistant CLT buildings that could be as tall as 20 stories high.
“We are working to minimize the amount of time buildings are out of service after large earthquakes,” CSM engineer Shiling Pei said in a statement. “We are also focused on cutting the costs required to repair them.”
Cross-laminated timber advocates say it can be used to construct buildings of equal strength and fire-resistance as those made of steel and concrete. It has also fueled the passions of architects and environmentalists, who believe it to be a much greener method for housing the world’s growing population.

Oregon-based Roseburg Forest Products will expand its operations in the southeastern United States with construction of a new engineered wood products plant in Chester, S.C. Roseburg publicly announced the project July 11 at a joint news conference with officials representing the state of South Carolina and Chester County.
“This is an exciting strategic growth opportunity in a business that has done well for us,” Roseburg President and CEO Grady Mulbery said. “With the continued increase in housing starts in the southeastern U.S., we see ongoing demand growth for engineered wood products in the region and elsewhere. We are grateful to state and local officials in Chester for their hard work and collaborative efforts to facilitate this project.”
Groundbreaking on the planned state-of-the-art manufacturing facility is expected in early 2018, with anticipated operation start-up in mid-2019. Once completed, the plant will create 148 full-time jobs.
“This new plant will be the most technologically advanced manufacturing facility of its kind in the world with the highest capacity continuous LVL press in the world,” said Steve Killgore, Roseburg’s Senior Vice President of Solid Wood Business. “Expanding our manufacturing capacity in this way allows us to meet growing customer demand for a versatile product that combines the best of modern processing technology and structural capability.”
The new plant will make Roseburg the largest U.S. manufacturer of engineered wood products serving independent distributors without captive distribution. Roseburg first established its engineered wood products business in 2001 and currently manufactures RFPI Joists, RigidLam LVL and RigidRim Rimboard at its plant in Riddle, Ore.

After receiving negative feedback from the industry, the Environmental Protection Agency (EPA) withdrew its Direct Final Rule Wednesday, removing delayed compliance dates for certain formaldehyde emissions standards on wood products.
“Since the direct final rule and proposed rule’s publication, EPA has received several comments on the proposed amendments to the compliance dates that the agency considers to be adverse,” the agency said.
Published in May, the Direct Final Rule gave the composite wood industry more time to comply with certain standards, including extending the deadline to meet emissions standards, record keeping provisions and labeling rules:
• Emissions, recordkeeping and labeling provisions – March 22, 2018
• Import certification – March 22, 2019
• Laminated products – March 22, 2024
The rule also proposes to extend the transitional period for CARB-certified third-party certifiers (TPCs) to March 22, 2019.
The EPA will instead proceed with a final rule based on its proposed rule published on May 24 after considering all public comments.
