Tulita is a remote hamlet in the Northwest Territories, Canada that Alta-Fab worked with to custom-design, build, and install a new town office and cultural centre to bring together the citizens in a comfortable space with a permanent feeling to gather, work, and connect.
Due to the extreme northern and remote location, the project presented many logistical challenges and innovative solutions. We ensured as much work as possible was completed in Alta-Fab’s plant to avoid the high costs of flying employees to the construction site.
The modules were built and tested in the Alta-Fab shop and then taken apart for shipping. All connections were checked for easy re-assembly and to guarantee they worked once on-site.
The modules and other materials were shipped by a barge, which ran on a limited seasonal schedule, due to the secluded northern location. We carefully planned the schedules to match up with the barge’s schedule. We also used innovative building methods because the barge’s capacity and the supply of building equipment in Tulita was limited.
With no access to cranes, our modules needed to be moved from barge and onto steel foundation piles with the equipment available. To do this, the structure of the modules incorporated a steel permanent handling frame, which also provided savings in the foundation structure.
To contend with extreme environmental conditions in the far north—where temperatures can reach as low as -54C, not factoring in wind chill—special attention was given to the building envelope, which was guided by local engineering experts.
We layered various insulation types and used a cost-effective heating and ventilating system comprised of oil-fired boilers, including primary and back-up boilers.
