The air terminal project was delivered through a public tender. Determining the methodology is a responsibility of the contractor delivering the project. In this case it is speculated that the contractor use an off-site construction because of the proximity of specialized trades and building materials in Hay River. This keeps the cost of construction down and avoids unnecessary delays. I'll add that the new air terminal building for the Trout Lake Airport is designed as a stick-built structure that will be transported by truck and arriving in Trout Lake soon as one item. The building is expected to arrive on site during the first week of March, and the Department of Transportation encourages the community to contact Rowe’s Construction to identify local job opportunities for the final delivery and set-up of the building.
