The Luxembourg six story, forty unit apartment building, was finished in Québec City’s Charlesbourg district in 2014. Construction was attracting attention in the industry for the simple, fast and safe materials used in the project. Excavation for underground parking at the Luxenbourg project got underway in September of 2013, with work on the structure beginning at the end of October. The Luxenbourg was erected at the rate of 10.000 square feet (929 m2) every three days. As of the first week of January 2014, all six floors were in place, windows installed and workers protected from the forces of nature. Peikko's DELTABEAM® Composite Beams made installation possible with this speed.

“It’s amazing how fast a building goes up” states Luc Lemieux, President and CEO of Logisbourg Inc., general contractor and developer. “Winter weather is not the hurdle it used to be with more traditional building techniques. Our project will be delivered on time for July occupancy.” What is the key to accelerated construction? “The off-site manufacture of building components,” promptly replies Lemieux. “Prefabricated steel beams and concrete slabs are delivered ready to install. The floor by floor assembly requires no expensive and time-consuming forms for poured cement.”

Maximum design flexibility

The DELTABEAM® itself might best be described as a trapezoidal steel beam with an extending “wing” on each side. The wing serves as support for the hollow-core concrete slabs which form the floor. Only the grout placed between slabs requires on-site preparation. As the steel beam is fully imbedded, the technique is popularly called “slim floor” construction.

The result is 30% lighter than a poured concrete floor, reducing the size of supporting foundations and the overall height of the building required to produce the same number of floors. As the floor assembly can be as thin as 10 inches (200 mm) and span as much as 45 feet (13.5 m) without a downstanding beam, there are few structural impediments to design, a feature particularly appreciated in an indoor parking layout. “The system provides a lot of flexibility to optimize living space, opening the way for architectural creativity and long-term options should a change of vocation be contemplated“, he adds. “Speed and efficiency aren’t the only advantages that have our colleagues in the industry peering over the fence,” says Lemieux with a touch of humour.

Reduced construction waste

On-site construction safety has also generated considerable interest at the Luxenbourg. Permanent precast concrete stairwells were installed as the building went up; there was no need for the temporary wooden structures which can often be a safety headache. Precast concrete requiring no forms also translates into far less construction waste, reducing disposal costs and making the project more environmentally friendly. “Our visitors have taken notice of just how clutter-free the site is,” points out Lemieux.

The DELTABEAM® provides also exceptional resistance to fire and can withstand exposure of up to two hours with no additional protection. It is the only steel beam in Canada to offer resistance to fire in the event of direct exposure.

Reliable technical assistance

“Since the various components of Peikko’s system come into place with a high degree of precision, there is little time lost in adjusting for margins of error when proceeding to the indoor phases of the project,” adds the affable Logisbourg CEO. “Peikko also provides engineering services and step by step technical assistance as construction progresses.” In addition to excellent soundproofing, future residents of the Luxenbourg will enjoy in-floor radiant heating and access to shared roof-top amenities. More than half of the units have already been reserved.
