One of the tallest wood buildings in the world will soon be constructed at UBC, providing housing for hundreds of students. When completed, the $51.5-million residence building will stand 53 metres tall (about 174 feet).

“This beautiful, new tall wood building will serve as a living laboratory for the UBC community,” said Martha Piper, interim president. “It will advance the university’s reputation as a hub of sustainable and innovative design, and provide our students with much-needed on-campus housing.”

Construction of the 18-storey tall wood student residence will begin later this fall, and the building is set to open in September 2017. It will house 404 students in 272 studios and 33 four-bedroom units, and feature study and social gathering spaces. There will also be a ground-floor lounge and study space for commuter students.

“This project shows that when it comes to building with wood, B.C.’s innovation can’t be beat,” said Steve Thomson, minister of Forests, Lands and Natural Resource Operations. “By taking advantage of new building technologies, we’re also expanding our markets for B.C. wood products – and supporting jobs in the forest sector.”

In addition to its primary function as a student residence, the building will serve as an academic site for students and researchers, who will be able to study and monitor its operations.

The tall wood building will consist of a mass timber superstructure atop a concrete base. Wood is a sustainable and versatile building material that stores, rather than emits, carbon dioxide. UBC aims for the building to achieve a minimum LEED Gold certification, a rating system that evaluates how environmentally friendly a structure is in its design and energy use.

UBC’s Student Housing and Hospitality Services, the Binational Softwood Lumber Council, Forestry Innovation Investment, Natural Resources Canada and B.C.’s Ministry of Forests, Lands and Natural Resource Operations are contributing funding for the building.

Any additional costs related to design and construction have been funded through external sources. Students will pay the same for rent at the tall wood building compared to similar accommodations at other student residences on campus.

UBC Properties Trust is managing the project. The project’s architect, Vancouver’s Acton Ostry Architects, is working in collaboration with tall wood advisor Architekten Hermann Kaufmann from Austria. Fast + Epp, another local firm, is the structural engineer.

BACKGROUND

The proposed location for the tall wood building is in an open area north of the North Parkade and adjacent to Walter Gage Road.

Other wood structure buildings on UBC’s Vancouver campus include the new AMS Student Nest and Engineering Student Centre, the Centre for Interactive Research on Sustainability, the Bioenergy Research and Demonstration Facility, and the Earth Sciences Building.

Earlier this year, the B.C. government passed the provincial Building Act, which enables innovation in building construction. The Building Act enabled the Province to develop a regulation to allow construction of UBC’s new tall wood student residence, with rigorous health and safety standards. The regulation was developed with the project design team, UBC’s chief building official and an independent building code consultant.

Rich Coleman, minister of natural gas development and minister responsible for housing

“When we introduced B.C.’s Building Act this year, one of our goals was to encourage innovation by creating an approval process for groundbreaking projects like this one,” said Rich Coleman, minister of natural gas development and minister responsible for housing. “As a result, we have been able to approve UBC’s tall wood building, while ensuring it meets rigorous health and safety standards.”

Cees de Jager, general manager of the Binational Softwood Lumber Council

“We’re thrilled to partner with UBC on this exciting project,” said Cees de Jager, general manager of the Binational Softwood Lumber Council. “The residence is a showcase of innovation and ingenuity that will contribute greatly to transforming how we develop taller wood buildings in the future. Lessons learned at UBC will stimulate increased use of wood throughout North America and beyond, benefiting our industry, our communities and our environment.”

Michael Giroux, president of the Canadian Wood Council

“The Canadian Wood Council congratulates UBC on its commitment to build a tall wood students’ residence,” said Michael Giroux, president of the Canadian Wood Council. “We are entering an exciting time for the Canadian and North American wood products industry. As the tallest wood building in Canada, this project will serve as a great example of the research and technology that is involved in taking wood construction to new heights – resulting in innovative solutions that are safe, sustainable and viable, and meet or exceed the requirements of the building code.”

About tall wood buildings

Wood is suitable as a beautiful finishing material and a structural material that meets safety and performance requirements. Wood structures, as with any building material, must meet building code requirements. Safety measures, such as sprinkler systems and fire resistance-rated wall and floor/ceiling assemblies, ensure tall wood buildings are built to meet and exceed fire safety and structure performance requirements.

FPInnovations, a forest sector research centre, conducted tests on the UBC building’s wood structural components. The building’s safety measures include enhanced fire protections and back-up systems, a building-monitoring system and an upgraded building core, the first in B.C. to be specified to the new 2015 National Building Code of Canada for seismic design.

A number of tall wood projects have been completed around the world in recent years. Today, the concept is gaining traction in North America as a safe, sustainable and cost-effective construction option.

The world’s current tallest wood building is a 32-metre (105-foot), 10-storey apartment building in Melbourne, Australia. Prince George’s Wood Innovation and Design Centre, completed in October 2014, is the tallest wood building in North America, standing at 29.5 metres (97 feet). A 51-metre (167-foot), 14-storey apartment building is now under construction in Norway. Two other tall wood projects have been announced for New York and Portland.

About UBC’s Student Housing Growth Strategy

UBC’s Student Housing Growth Strategy is an aggressive plan to meet the growing demand for on-campus student housing. The strategy will add more than 2,000 beds by 2017, and an additional 640 beds in 2019.

About 10,000 students currently live in university-operated student housing on UBC’s Vancouver campus, which offers more student housing than any other Canadian campus.

Cross Laminated Timber would be my guess for materials. Construction Type? Heavy Timber maybe? Height would be a problem under the ICC

It is under our code too. They must be using an alternate solution to address fire.

The building is to conform with the BC Building Code [derived from the National Model Building Code of Canada NBCC] and an additional regulation written by the Provincial Government to regulate the use of mass timber construction to be compliant with the code for structural and fire safety. The fire resistance of the mass timber is to be 2 hrs, this is to be achieved by multiple layers of gypsum, charring is not part of the program. Fire sprinklers are to NFPA standards and 30 min back up water supply. Seismic resistance is to be achieved by 2 concrete stair elevator towers, the mass wood is to have steel connections and steel drag straps back to the towers, 1st storey is a concrete podium.

Tall Wood: A high tech Frankenstein of a building

Similarly to CLTs, glulam takes lumber, glues it together with moisture-resistant adhesives, except in glulam, all the wood has the grain going the same way, giving it strength in one dimension lengthwise.

The CLTs are stacked between glulam pillars and connected by steel connectors to form the floors and vertical support for Brock Commons. However, the wood needs help to make the building strong enough to stand 18-storeys high.

“In simple terms, you can break a high-rise building into two parts. There is the portion that resists all the lateral forces — we call it the ‘lateral force resisting system,’” said Adebar. “We call the rest of it a ‘gravity frame’ — the floors and the columns and all that. You need something to take the vertical load — all this needs to do is to resist [gravity].”

To stop the building from tipping over, Brock Commons has two giant concrete towers. To prevent the building from collapsing under its own weight, Brock has wood floors and columns connected by steel connectors.

When Adebar and other structural engineers look at Brock Commons, they don’t see a building that’s much different from a skyscraper in Toronto or Vancouver — at least when it comes to earthquakes or wind.

“The timber portion of the structure doesn’t do anything to resist wind loads or earthquake loads,” said Adebar. So vertically, Brock Commons is just a plain old reinforced concrete building, but plain old reinforced concrete is really good at stopping buildings from falling over because of wind of earthquakes.

“Wood structures actually perform quite well in a seismic event because they are relatively light. There isn’t a lot of mass or inertia that is generated during a seismic event. That’s a benefit of a wood structure,” said Metras.

All wood does horizontally, explained Adebar, is change the calculations because it’s so much lighter than concrete or steel.

It’s in resisting gravity — in the vertical direction — that the building is primarily wood. Buildings are heavy and need to support their own weight, plus the weight of all the showers, toilets, people and beds on each floor. All together, those forces make up the gravity load.

“We have steel connectors that connect the columns at each floor level, and they allow for the loads to be transferred straight down the building through the columns and not produce any stress on the wood floor plates,” explained Metras.

The weight of the eighteenth floor goes through the steel connectors down the wood column between floors 17 and 18. Then, at the seventeenth floor, the weight passes through another steel connector to the next column — the one between the sixteenth and seventeenth floors. This happens all the way down the building until the weight hits the concrete foundation, where the concrete and the ground support the building’s weight.

“It’s a beautiful use of different materials,” said Adebar.

The steel joints that connect the wooden columns to the floors play an important role in the vertical support of the building. They allow the weight of the building to be transported straight down the building instead of spreading the weight over each floor. This takes strain off the floors and makes sure all the weight is taken down to the concrete foundation.

The building also has built in sensors to monitor its function over time. The sensors will measure moisture and how much the building moves and deforms.
