Brock Commons Tallwood House is an 18-storey student residence at the Point Grey Campus of the University of British Columbia (UBC) in Canada. At the time it was opened, it was the tallest mass timber structure in the world. [1]

Contents

It is the first phase of a complex at Brock Commons. [2] The Brock Hall Annex located at the site will be demolished to make way for a building in phase 2. [3] The 1958 mosaic mural "Symbols of Education" by Lionel and Patricia Thomas, commissioned by the university's 1958 graduating class, will be moved as a result. [3]

Construction

It was built via the Tall Wood Building Demonstration Initiative (TWBDI) of Natural Resources Canada [4] that in October 2017 led to the establishment of the Green Construction Through Wood (GCWood) program. [5] Acton Ostry Architects designed the building with structural engineering firm Fast + Epp, which received consultation services from Architekten Hermann Kaufmann of Vorarlberg, Austria, for tall-wood construction. [6] Before raising the building, a two-storey 8-by-12-metre (26 ft × 39 ft) mock-up was built [7] on site to test wood-to-wood connections and the stability of the structure. [8]

Site construction began in November 2015, and topped out in August 2016. [9] Construction of the structure and facade began in June 2016 [7] and was completed by a work crew of nine individuals in 57 days, [10] rising at a rate of about 2 floors per week. [9] The construction team described the assembly procedure to be "like Lego". [9]

The building was subject to the 2012 British Columbia Building Code, which limits wood buildings to six storeys. [7] This necessitated a special approval, as well as two structural reviews. [7] The first review, completed by Merz Kley Partner ZT GmbH of Dornbirn, Austria, focussed on the timber structure. The second was a seismic review conducted by Read Jones Christoffersen Consulting Engineers of Vancouver. [7]

The project cost $51.5 million to complete, [6] and was designed to satisfy LEED Gold standards. [2]

Description

The 53-metre-tall (174 ft) building has a capacity to house 404 students, primarily for graduate and upper-year undergraduate students, with a floor space of 15,120 square metres (162,800 sq ft). [6] It consists of 33 four-bedroom units, 272 studios, study spaces, and lounges. [6] The top floor is devoted to a lounge. [8]

The frame is built of pre-fabricated engineered timber [11] manufactured by Penticton-based Structurlam, and the structure also consists of a concrete foundation and steel components. [6] The floors above grade are made of five-ply cross-laminated timber, [7] anchored to the glulam columns using steel connectors. [6] The latter were used to comply with the 2015 National Building Code seismic design requirements. [9] The roof is steel-framed, composed of pre-fabricated steel beams supporting a metal deck. [2] The structure is anchored by two concrete cores spanning its height for lateral stability that also function as the staircases for the building. [7]

The wood structure is panelled with drywall, chosen to satisfy fire safety codes and more quickly obtain municipal permit approvals. [8]

Legacy

As a result of TWBDI and the structure's construction, amendments to the 2020 and 2025 National Building Code of Canada were proposed to permit the construction of tall wood buildings. [5] The British Columbia building code was amended in March 2019 to allow the construction of mass timber frame buildings of up to 12 storeys. [10]

The building is fitted with accelerometers, inclinometers, moisture meters, and vertical shortening string potentiometers. [7] The data collected will be analyzed by a research team at UBC to determine the building's performance relative to its design. [7]

<span class="mw-page-title-main">Skyscraper</span> Tall habitable building

A skyscraper is a tall, continuously habitable building having multiple floors. Modern sources currently define skyscrapers as being at least 100 meters (330 ft) or 150 meters (490 ft) in height, though there is no universally accepted definition, other than being very tall high-rise buildings. Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s. Skyscrapers may host offices, hotels, residential spaces, and retail spaces.

<span class="mw-page-title-main">Engineered wood</span> Range of derivative wood products engineered for uniform and predictable structural performance

Engineered wood, also called mass timber, composite wood, man-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, or veneers or boards of wood, together with adhesives, or other methods of fixation to form composite material. The panels vary in size but can range upwards of 64 by 8 feet and in the case of cross-laminated timber (CLT) can be of any thickness from a few inches to 16 inches (410 mm) or more. These products are engineered to precise design specifications, which are tested to meet national or international standards and provide uniformity and predictability in their structural performance. Engineered wood products are used in a variety of applications, from home construction to commercial buildings to industrial products. The products can be used for joists and beams that replace steel in many building projects. The term mass timber describes a group of building materials that can replace concrete assemblies.

The Sun Tower is a 17 storey 82 m (269 ft) Beaux-Arts building at 128 West Pender Street in Vancouver, British Columbia. It was known for its faux-patina steel dome painted to imitate copper cladding. In early February 2021 a newly finished roof clad in real penny-coloured copper tiles was revealed. The new roof was a part of restoration work that began on the heritage building in 2018. Nine nude muses, the "nine maidens" supporting the cornice line can be seen. The terracotta for this building, including the ladies, was made in Tamworth, Staffordshire, England by Gibbs and Canning Limited.

<span class="mw-page-title-main">Cross-laminated timber</span> Wood panel product made from solid-sawn lumber

Cross-laminated timber (CLT) is a wood panel product made from gluing together at least three layers of solid-sawn lumber, i.e., lumber cut from a single log. Each layer of boards is usually oriented perpendicular to adjacent layers and glued on the wide faces of each board, usually in a symmetric way so that the outer layers have the same orientation. An odd number of layers is most common, but there are configurations with even numbers as well. Regular timber is an anisotropic material, meaning that the physical properties change depending on the direction at which the force is applied. By gluing layers of wood at right angles, the panel is able to achieve better structural rigidity in both directions. It is similar to plywood but with distinctively thicker laminations.

Pres-Lam is a method of mass engineered timber construction that uses high strength unbonded steel cables or bars to create connections between timber beams and columns or columns and walls and their foundations. As a prestressed structure the steel cables clamp members together creating connections which are stronger and more compact than traditional timber fastening systems. In earthquake zones, the steel cables can be coupled with internal or external steel reinforcing which provide additional strength and energy dissipation creating a damage avoiding structural system.
