Canada’s heritage top of mind in library restoration
Library of Parliament a source of national pride after extensive overhaul
As Canadians celebrate the country’s 139th birthday this weekend, one of our most cherished buildings, the Library of Parliament, has regained its former lustre in the wake of an ambitious, multi-year and multi-million-dollar rehabilitation project.
Preceded by seven years of preparation, work got under way in March 2002 to conserve, rehabilitate and upgrade the landmark heritage structure. No aspect was overlooked, from the weathervane atop the roof to the cramped and crowded basements below ground.
“We have taken a building that was deteriorating and preserved it as a legacy for future generations,” says Michael Fortier, Minister of Public Works and Government Services.
That job fell on the shoulders of a team that included Ogilvie and Hogg, Desnoyers Mercure et associes, Spencer R. Higgins and Lundholm Associates, architects in joint venture and general contractor Thomas Fuller Construction Co. (1958) Ltd.
“It was a huge challenge, but we got it done,” says company president Bill Fuller.
His firm was awarded a $52 million stipulated sum contract in January 2002.
A decade earlier, the firm had completed a two-year conservation project at the Peace Tower.
The library holds a special place in Canadian history. It is the last remaining part of the original Parliament Building, the Centre Block on Parliament Hill, and the only section to survive a devastating fire of 1916.
The rehabilitation project included repairs to the masonry, windows and ironwork. The building structure was stabilized and seismically upgraded, and the three roofs were replaced.
As well, three new basements were created: two for the collections and support areas and one for new mechanical systems that provide superior control of air quality, humidity and other indoor environmental elements.
The electrical, communications, security and life-safety systems were upgraded to meet current health and safety standards and the library’s future needs.
Substantial completion was achieved in mid-May.
Fuller, whose firm had a supervisory staff of between eight and 10 on site at any given time, said rehabilitation of the national landmark presented its share of challenges from a construction perspective.
“I guess the biggest risk from both our perspective and that of Public Works and Government Services Canada was creation of the three new basements,” he said. “We had to go down about 30 feet in rock below the existing structure.
“We weren’t allowed to drill and blast to any extent.”
As a precautionary measure, devices were installed to monitor rock movement in the area.
After “a bunch of techniques” were explored, subcontractor Dibco Underground Ltd. used Korean rock splitters to help get the job done.
“Use of heavy machinery wasn’t much of an option until we got the rock (excavation) down to the point where we could physically get the equipment in below the library,” Fuller said.
Access to the exterior of the 130-year-old building also was an issue. Repairing the building envelope — roof, windows and masonry walls — was a key element of the project.
Fuller Construction erected an innovative, self-supporting scaffolding system that didn’t touch the building, yet allowed ready access.
The building’s interior was repaired, refurbished and modernized as well, in keeping with the “minimal intervention” strategy developed at the outset by the architectural team.
PUBLIC WORKS AND GOVERNMENT SERVICES
The intent was to respect the library’s original design and construction while adding modern details and components.
Virtually everything from the plastered dome above the central reading room to the intricate parquet floor below was rehabilitated.
Sophisticated mechanical systems were installed that permit, for the first time in the building’s history, fine-tuned control over temperature and humidity levels as well as air circulation.
“There were a lot of space constraints,” Fuller said. “We didn’t have a lot of room to put in the new mechanical and electrical systems.”
Close co-ordination of the subtrades was also critical during the course of construction.
Some 50 subcontractors were involved in the project, from stonemasons and wood conservators to bricklayers and metal fabricators.
The project was undertaken by Public Works and Government Services Canada in collaboration with the Library of Parliament. The building was officially transferred back to Parliament late last month.
