On October 21st 2016, the UBC CSCE Student Chapter invited Alex Thompson to give a presentation on the Challenges of Design and Construction in the High Arctic. In 2015, Alex spent most of the summer on a construction site in Nanisivik located on the northern tip of Baffin Island in Nunavut. While he was there, he witnessed many of the challenges associated with having a project site located so far north. Project equipment and materials had to be shipped in by boat and required over two months of travel time to arrive on site. This meant the contractor had to plan well ahead of time in order to meet project deadlines. The project required on-site mechanics and several spare parts for their machinery in order to quickly repair any equipment malfunctions instead of having replacement parts shipped. Due to permafrost conditions, the foundation designs required that the top layers of soil be removed until a layer of soil that would remain permanently frozen was reached. The excavation was then backfilled with non-frost susceptible soil to achieve a firm foundation to build upon. In addition, the project had to generate all their own power using diesel generators.
