Among this year’s winners were two adaptive re-use projects, both of which re-purposed former silos. The first—The Silo in Copenhagen, Denmark, which received the award for Best Tall Building Europe—preserved as much of its original structure as possible and was re-designed by Danish architecture firm COBE as a residential high-rise in a formerly industrial area.
“For architects, one of the hardest jobs of working on an adaptive reuse project like this is that you can fall in love with the original structure—which in this case was the old silo; this monolithic, slim, and esthetically pleasing building,” said Caroline Nagel, project director with COBE. “In this instance, it was a question of how you can transform the original structure into a livable building that still contains the old soul of the silo.”
“There were very loud calls for the original structure’s demolition, and there is no surprise as to why: it is valuable real estate, and it is much less risky to build something new,” said developer Mark Noble. “My response to that was, why would you do that? It was the mix of old and new that drew us to the project, and there are multiple layers of history there. We did not want to wipe the slate clean, and what would you replace it with that has this much power?”
This year’s top honour for the Americas went to American Copper Buildings in New York City. Designed by SHoP Architects, the dual residential buildings are connected with a skybridge, 91 m (300 ft) in the air. The bridge features a pool, which allows residents to swim between the two sites.
The World Trade Center Master Plan (Studio Daniel Libeskind), also in New York City, won the Urban Habitat award, which recognizes significant contributions to the urban realm in connection with tall buildings. Additionally, New York Times Tower (Renzo Piano Building Workshop) received the 10 Year Award, which honours a project completed in 2007.

Connectivity and mobile technologies can help contractors gather accurate and timely data from the field, reliably control costs, and more efficiently manage their equipment fleets, according to a new study from Dodge Data & Analytics, in partnership with B2W Software. These improvements are expected to better connect field, office, and maintenance operations to better manage heavy construction projects.
“The Dodge Data & Analytics study confirms that heavy contractors are struggling to capture data and use it to optimize project performance and resources, and that there are significant opportunities for them to improve in these areas through the right technologies and mobile capabilities,” said Paul McKeon, CEO of B2W Software.
The study determined that contractors believe a range of current and emerging technologies, from mobile devices/applications for project management to big data analysis, will provide more accurate data from the field, thus improving project management. The study also reported data captured in the field (i.e. information on project/employee performance and safety) must be accurate and timely in order to be useful for effective decision making; however, latency and errors remain a challenge in heavy construction.
“This lag in the exchange of critical data between field and office, and the concerns about its accuracy, seriously interfere with heavy contractors’ efforts to improve performance,” said Steve Jones, senior director of industry insights research with Dodge Data & Analytics.
The study also found tracking and maintaining fleets in the heavy construction market can be a significant drain on both budget and human resources, with many contractors continuing to rely on spreadsheets and paper for these processes. Contractors employing specialized software, telematics, and mobile applications reported they manage their equipment more effectively, can better optimize resource utilization, and increase equipment uptime.
Dodge Data & Analytics will host a series of webinars exploring these findings. To learn more, click here.
What are the main problems relating to the state of wood-framed construction in Canada?
All over the country, I am seeing restorations—which, traditionally, have been reserved for either replacing components that have reached the end of their service or for a simple ‘face-lift’—for buildings less than 10 years of age.
In my hands-on role as principal at an engineering firm, I spend most of my time investigating building envelope failures in relatively new buildings. More and more often, property owners have to restore buildings which were built using new materials and technologies, based on designs that complied with current building codes. This is because improperly constructed building envelope assemblies often lead to massive structural failures.
A mess of a site In 2013, my firm was called to a complex with more than 40 high-end, townhouse-style condominiums in Alberta, with units which had originally been sold for approximately $1.5 million each. The buildings had been constructed from 2007 to 2009, so this was a fairly new build. However, residents were already reporting issues of top-floor leaking to building management.
Before beginning my site review, I stood across the street from the site and noted the appearance of the buildings. There was evidence of ice dams—I could see the ice hanging out over the soffits and eaves—but something else concerned me: the homes were not level. They appeared to be slightly bowing.
Once I reviewed the condominium’s attic space, additional issues became apparent:
While the roofs had vented, aluminum soffits, these installations were not able to perform their “air-supply” role due to being either plugged with insulation or covered with plywood from above.
The firewalls between the townhouse units had never been sealed. They had water stains running down the sides of the open joints.
A layer of dust atop the insulated ducts running through the attic space was decorated with spots, caused by dripping water that had condensed and fallen from the protruding roof nails above.
The installed polyethylene vapour barrier not been sealed to the pot-lights penetrating the top-floor ceiling.
I determined the ice damming was a direct result of too much warm, moist air escaping into the attic space and that the blocked soffit vents had prevented the natural convection air-flow. This warm air melted the snow on the rooftop and the water froze again as it moved toward the cold outer edge of the roof. Without adequate convective ventilation where warm air rises to the top and escapes to the exterior while drawing in cool, dry air from the lower soffit areas, I could seal the vapour barrier, but I knew the ventilation problem would pose a challenge.
As the roofs only had 102 mm (4 in.) soffits and only a 3/12 pitch, there was no easy way to introduce soffit ventilation from either the interior of the attic space or from below the overhangs. We needed to remove a 1.2 m (4 ft) strip of roof deck sheathing from the entire perimeter of the rooftops to open blocked vents and install insulation baffles to keep the insulation from plugging up the ventilation. This ended up costing approximately $400,000 in roofing, ventilation, sealing, and firewall repairs—nearly $10,000 per unit.
While working on this challenge, the condo board of directors asked my team to complete a full condition assessment of the rest of the site. The first step was to perform an extensive visual assessment to determine what symptoms are present that might point to underlying issues. In my experience, the perfect time to do this kind of work is in the rain. These conditions provide inspectors with a free water-test, which can help locate all of the potential weak points in the building envelope.
When performing the visual assessment, my team observed many alarming issues, including:
staining at the balcony columns;
drip patterns at windows with no flashing;
little evidence of sealants;
step cracks throughout the field of the brick veneer masonry;
cladding in direct contact with the ground; and
panels of masonry leaning away from the building.
Having identified some areas of concern, we then began a round of exploratory dismantlement. We cut into the brick veneer and found reverse lapped building paper and membranes. We cut into the supposed stucco and found 25 mm (1 in.) thick expanded polystyrene foam insulation with only a finish coat of cementitious material installed. We opened corners at windows and found reversed lapped membranes and broken miter joints on the window frames themselves. We opened sections of the stained columns and found severe structural decay. Finally, we opened the drywall in the garage ceilings and found grossly under-sized main structural beams.
With the undersized main beams threatening occupancy, we had to emergency shore each unit.
The extensive problems with the building envelope required a complete re-cladding of the site. After design and competitive tendering, the repairs were estimated at about $7 million—roughly $165,000 per unit, plus $10,000 in roof repairs. In addition to the costs, property values were quickly dropping to about 50 per cent of what homeowners had paid to purchase the units five years earlier.
Significant re-construction We began re-construction work in the spring of 2016. The entire site was enclosed and protected with scaffolding. Upwards of 100 tradespersons were onsite every day. My team and I provided daily site review services and contract administration.
As the demolition phase commenced, it became apparent the issue of decay was far more widespread than initially considered. Columns of three-ply 51 x 152 mm (2 x 6 in.) studs that were only a few years old had decayed to the point where you could literally poke your finger through them. Additionally, widespread areas of sheathing had decayed to the point of total deterioration.
When it came to removal of the brick veneer, large panels were found to be only anchored by a few brick ties, while other areas had way too many. As for the faux stucco, the through-wall flashing was simply a dummy; there was no through-wall installation.
The racking in the structure, which had resulted in the breaking of the window frame joints, was the most challenging aspect of the project. We had to carry out interior shoring and replacement of the major beams all while the units were fully occupied.
For the re-construction and re-cladding, a new moisture and air barrier was applied to the entire shell. New windows were flashed in, following repeated mock-up attempts to get the process right. A drained exterior insulation and finish system (EIFS) was installed, as well as new brick veneer masonry structural columns, sheathing, balconies, garage doors, and eavestroughs.
We finished construction in November 2016. All-in-all, the job took eight months.
The original jobsite appeared to have the markers of responsible craftsmanship. The required paperwork was stamped by engineers. A foreman oversaw construction. City inspections were performed and architectural certificates were issued. Everything appeared to have been done properly and to code—on paper. In reality, it was apparent corners were cut and risks were taken to minimize construction costs.

When designing the Towers of Love, Toronto-based architect Alva Roy aimed to evoke an emotional response from onlookers. The 22- and 24-storey towers stand alone, yet together. Each structure is contoured in such a way as to draw the eye to its mate. The result, Roy says, is a testament to the depths of romantic love and union.
“Love is when two entities join to become one,” says Roy. “I went to meticulous care to make sure that this design would be emblematic of this inextricable bond that is the very essence of love.”
With an end-date of April 2022, plans for the multi-use facility include hotel, restaurant, and office space in one building, while the other will house commercial and residential units. The proposed development will be built in the Toronto area.
“Architecture is not just a wall, a floor and a ceiling to house ourselves,” says Roy. “It is a place where we connect to the deepest emotions of the human heart. Where we invoke peace and calm—and where we summon the richest parts of our being and existence.”
The Royal Architectural Institute of Canada (RAIC) has announced Toronto-based studio RDHA as the recipient of its 2018 Architectural Firm Award. One of the country’s oldest practices, RDHA has recently undergone a successful renewal, introducing new and creative players who strive to produce high-calibre, innovative architectural design.
“There is a remarkable consistency throughout the last 10 to 15 years of work by a younger generation of designers that have kept [RDHA’s] lineage and re-established themselves as a leading designing firm in Toronto,” said RAIC’s five-member jury about the studio. “For the successors to rebuild the firm and reputation and deliver a fresh portfolio of completed projects is exceptionally difficult.”
Recent RDHA projects include:
Waterdown Library and Civic Centre—Hamilton, Ont. (2015);
Lakeview, Port Credit, and Lorne Park Libraries—Mississauga, Ont. (2011);
Hamilton Central Library and Farmers’ Market—Hamilton (2010);
Bloor/Gladstone District Library—Toronto (2009);
Williams Parkway Operations Centre—Brampton, Ont. (2017); and
Surrey Operations Centre—Surrey, B.C. (2016).
Founded in 1919, RDHA has produced a wide range of work across Canada, including corporate headquarters, embassies, industrial facilities, academic buildings, and libraries. In 2005, the firm’s partners decided to change the nature of the firm by re-defining RDHA’s office structure and creative design process, which attracted the attention of young talent.
Since the shift, RDHA and its current partners—Tyler Sharp, Geoff Miller, Bob Goyeche, Rob Boyko, and Momin Hoq—have received significant recognition and praise. In addition to this year’s Architectural Firm Award, the studio has won more than 40 major design accolades in the past 10 years, including three Governor General’s Medals for Architecture. Additionally, Sharp received the RAIC 2014 Young Architect Medal.
Construction has launched on Tour des Canadiens 3 (TDC3), the third phase of a project in downtown Montréal’s new Quad Windsor neighbourhood. Designed by IBI Group with Béïque Legault Thuot Architectes, the 53-storey residential building is slated to house 565 units, including a dozen townhouses.
Named for Montréal’s National Hockey League (NHL) franchise, the Canadiens, TDC3 will feature a ground-level café connected to an adjacent park, as well as adaptable party rooms, a fitness centre with an indoor pool, a modern game room, and SkyLounge on the building’s 55th floor. An above-ground skybridge will provide residents with direct access to the Montréal métro, as well as to RÉSO, the city’s underground path network. The bridge will also provide direct access to Réseau express métropolitain (REM), Montréal’s new $6.3 billion light rail transit (LRT) system, which is due to open in summer 2021.
With a $2 billion investment from real estate development firm Cadillac Fairview, the Quad Windsor neighbourhood is expected to draw nearly 6000 new residents and 6500 new workers within the next 10 years. When completed, the mixed-use community will include a 2-acre (0.8-ha) park, office buildings, residential towers, dining, shopping, and cultural exhibitions.
The first phase of the development’s construction, the 50-storey Tour Des Canadiens, was completed in May of 2016, while the second, the 53-storey Tour des Canadiens 2 (TDC2), is expected to finish in 2019. TDC3 will finish construction in 2021.
The Fraunhofer Project Centre for Biomedical Engineering and Advanced Manufacturing (BEAM) is considered an innovation centre at the crossroads of life sciences, medicine, and engineering. Diamond Schmitt’s re-design of the open-concept 1858-m2 (20,000-sf) space created accommodations for office, research, and manufacturing facilities. Additional space of the same size on the building’s second floor will eventually house laboratories and administration offices.
Researchers at the facility will develop cell manufacturing systems related to cell therapy and immunology and advance technologies for eye care, point-of-care medical devices, and cancer treatments.
“The new facilities will ensure BEAM scientists have the infrastructure required to move their research on biomaterials, diagnostics, and cell therapies into market-ready technologies,” says Frank Emmrick, director of the Fraunhofer Institute.
Diamond Schmitt re-purposed the facility with an open design concept to create a flexible, re-configurable space where resources can be shared among working research groups.
“A flexible modular approach defines the layout and planning of the Containment Level 2 Laboratory Zones,” says John Featherstone, principal with the firm. “Open concept island benches with top down servicing achieve the maximum amount of serviceable floor space for equipment and benching while maintaining safe distances between facing work areas for circulation.”
Situated on more than 0.8 ha (2 acres) of property along the St. Lawrence River, the 218-m2 (2350-sf) modern farmhouse revival was the vision of baby boomers Pierre Chevrier and Suzanne Rhéaume, designed by Québec firm Tergos. Awarded certification under LEED v4 Building Design and Construction (BD+C) Homes, the ecologically responsible design features adaptive elements, which can be altered to suit the changing mobility and accessibility needs of the homeowners.
“LEED v4 convinced me that my home would be adapted not only to my personal needs for a healthy lifestyle as an active senior, but also as a worthwhile investment I would not regret leaving for our children and grandchildren,” said Rhéaume. “This was a self-build project that became a passion of ours as we networked, researched, and rolled-up our sleeves. Achieving the Platinum level is very rewarding, but what is even more gratifying is knowing that this home was a grassroots endeavour. It was built by someone’s mom and dad, grandma and grandpa.”
The home’s features include:
a highly-insulated, airtight building envelope;
an air exchanger and opening windows on the river-facing side of the house;
energy efficient appliances;
light-emitting diodes (LEDs) and natural lighting;
rainwater harvesting and well water usage; and
a rain garden, xeriscaping, food forest, and permaculture.
