New mass timber products are becoming more widespread and encouraging builders, designers, and engineers to search for the best applications for mass timber initiatives. A few of the mass timber building products available today include:
• Cross-laminated timber
• Nail-laminated timber
• Glue-laminated timber
• Dowel-laminated timber
As they test the capabilities of these materials, designers are looking to existing mass timber buildings around the world for examples and inspiration.
Canadian and European researchers and architects began experimenting with the design of mass timber buildings in the 1970s. European timber projects have shown that weight matters with structural systems, and mass timber structures weigh up to one-third as much as their concrete counterparts. This fact has made wood construction a viable prospect in places where building height and weight are limited, such as city utilities, subway tunnels, and underground rail yards.
Due to their lighter weight, mass timber buildings are more resilient in seismic zones. They carry less inertia, so the possibility of destructive swaying goes down. This approach was recently applied in the Brock Commons tower, an 18-story college residence designed for the University of British Columbia by Canadian firm Acton Ostry Architects.
The 173-foot-tall tower combines glue-laminated columns, cross-laminated timber floor slabs, dual concrete cores, and steel connectors. The cores help to counteract wind-generated and seismic forces while anchoring the mass timber building in place. It meets structural and fire-safety regulations by utilizing a specially designed set of interdependent finishes and building materials.

Modular construction, using timber as a key element, is a credible solution to fast and sustainable house building. However, Metsä Wood believes that more needs to be done in terms of sharing knowledge and innovation in wood construction to further advance the use of this material in mainstream construction.
In order to help facilitate this process, Metsä Wood has launched its Open Source Wood initiative at www.opensourcewood.com. Metsä Wood’s Executive Vice President, Esa Kaikkonen, explains: “Not enough knowledge about modular wood design and building is shared, so wood construction remains niche. There is plenty of innovation but it is difficult to find, so Open Source Wood is our solution. We believe that with open collaboration the industry can achieve significant growth.”
The potential of wood is undeniable and today, offsite construction has major aspirations. Prefabricated wood elements enable fast, efficient and environmentally sound design without reducing quality. Reports on the benefits of such a lean approach are compelling: In a study of companies that have applied lean construction methods, 84% report higher quality in construction and 80% experienced greater customer satisfaction.
The report also highlights that almost 70% of projects that used prefabricated elements had shorter schedules and 65% had decreased budgets. Timber prefab construction also reduces other inconveniences such as the constant unloading of building materials, as well as the amount of on-site waste and the need to transport it.
Innovation in the house building sector is key, and offsite timber construction could be key in achieving the high volume of housing required. Using new and innovative products like Metsä Wood’s Kerto LVL (Laminated Veneer Lumber), homes constructed offsite can be turned around in a matter of weeks. Modern engineered wood products can be used for a variety of housing projects ranging from terraced and detached homes through to apartment blocks several stories high.

Roofs made from wood are one or the rarest roof types to find around these days, as concrete slab and shingles take over, according to Choice Solutions Roofing and Exteriors Co. In Oklahoma City.
Wood is not seen as strong as some other materials when it comes to construction, but in general well-maintained roofs made of wood can have a lifespan that ranges from 30 to 50 years. Having a wooden structure on top of a house has several good qualities, and it can look great. Here are some examples of wooden structures which are not the average roof that will provide an idea of how unique and marvelous structure topped off with wood can become.
The Centre Pompidou Metz has a hexagonal pattern of a load-bearing timber roof structure which is visible at night through its transparent covering membrane. It is interesting to know that the inspiration of the roof comes from a woven Chinese hat. Before this one-of-a-kind structure was created, it was studied from every angle to ensure that it would withhold heavy weather conditions. This woven like structure roof is made out of wooden beams, spaced 2.90 meters apart, forming a hexagon pattern that is 90 meters wide.
The timber used is glue laminated which enables the different lengths of the beams and makes them more resistant. It is without a doubt an astounding structure due to its complex curves and counter curves and therefore it is one of the most challenging and largest structure built up to date.
The mesh can allow the roof to expand 40 meters, made from protective fabric which consists of fiberglass and Teflon, forming a membrane over the wooden structure. This layer helps the inside temperature to stay natural. This building was created for displaying art and the goal behind the innovative structure was to draw tourism to Metz, France.

Following the general election held on June 8th, The Confederation of Timber Industries (CTI) announced the reconstitution of the Timber Industries All Party Parliamentary Group (APPG); their first annual general meeting (AGM) was July 12th at the House of Commons.
The Timber Industries APPG will help promote timber as the most sustainable and renewable building material and develop initiatives and economic measures to grow the whole UK Timber Industry supply chain. The Confederation of Timber Industries will assist Parliamentarians in their work by acting as the group’s secretariat and providing relevant information and logistic support.
The timber sector is in the top 50% of manufacturing industries in the UK, attracting investment and supporting jobs across the manufacturing and construction sectors, and adding over £10 billion per year to the UK economy. Every constituency in the UK benefits from jobs provided by our sector, whether in construction, manufacturing or distribution.
“We are pleased to see such widespread, cross-party support for our Industry,” said Roy Wakeman OBE, Chairman of the CTI. “The timber sector represents a major engine for the growth and development of the UK economy and, with the help of the Timber Industries APPG, we can deliver this message straight to key decision makers in Westminster. The CTI will be on hand to provide assistance and information to any MPs interested in the Industry, along with arranging regular visits to timber operations all over the country.”

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.
