Project Profile: Prefabricated Light Steel Framing and Prefab Panels save time
The reality behind Interbuild Limited’s pre-fabricated lightweight cold formed steel wall, structural floor and roof framing systems is simplicity and efficiency.
Interbuild’s pre-fabricated steel wall panels, together with a faster construction time make these materials a no-brainer – a cost-effective alternative to traditional building. That is why Habitat For Humanity used this method for a recent project in Hamilton.
“The trigger for the project was the Habitat for Humanity Canadian Conference coming to Hamilton,” said Tom Vert, Vice-President of Manufacturing for ArcelorMittal Dofasco. “We were trying to figure out what we could do differently for that conference and we brainstormed saying, it’s Steeltown, why don’t we build a steel house during the conference?”
Vert added that, for the project, he did some research on companies that do steel prefab housing. “In Ontario there are approximately three companies that do it,” he said. “We went and did some research and found that Interbuild was the best fit for us. They had the product, they had the ability to do it and Ivano was kind enough to donate his time and expertise to do the design work as well as to the fabrication and installation.”
The Ivano that Vert is referring to is Ivano Minatel, the owner of Interbuild Limited, a company which specializes in prefab Cold Formed Steel applications. “We have both an engineering-based firm here and an installation company,” said Minatel. “On the engineering side, from an architectural drawing, we will design the LSF walls and roof systems, if that should be the case, as well as some of the floor systems.”
Minatel then outlined the rest of the process, saying that everything is integrated together in Revit format so there is an actual model to work from. Interbuild then manufactures all the walls and ships everything out to the build site and they install it
The frame of the building was constructed by Interbuild using state-of-the-art 3D modeling software to design and frame all the cold formed steel load bearing and non-load bearing walls.The prefabricated wall panels are assembled off site. The panels are then shipped to the site and installed, negating the need for space to build and store the materials on site. The floor system in this case for a single dwelling is CFS joists pre-panelized floor with plywood sheathing.
After construction of the structural frame was completed, traditional interior steel stud partition walls were installed to complete the interior framing.
The process is “at least as good as traditional construction and in certain applications, style and types of building, it is a much better application,” he said. Regarding the Habitat for Humanity Hamilton project, the construction portion was done in 3 days for a two-floor structure. “It is a concrete slab with two floors and a roof,” said Vert, who also has a lot of praise for the process. “If you try doing steel studs by stick-and-frame, it takes a long time. By doing it prefab in a warehouse, you just drop all the sections right in place. The first floor was done in just three hours.”
Vert pointed out that “speed of installation and construction” are the main benefits. “You know that when you build it in a factory, you’re not affected by any kind of weather.”
By using prefabricated wall panels, pre-assembled roof trusses and selected floor systems, Interbuild can complete your project in a fraction of the time that it would take with wood/concrete frames.
Wall Panel, Floor and Roof layout drawings are used for coordination by the on site erection team. This process ensures that the shell structure is built accurately and on schedule.
In-house Engineers provide structural designs according to the International Building Code, United States Building Code, the National Building Code of Canada and Building Codes for the Caribbean.
