Allnorth was retained by Exploits Engineering and Exploits Land and Sea to perform quality control for concrete placement and soil compaction/inspection at the Grinder Building located in the Hydro Facility at Grand Falls-Windsor, NL. The quality control program consisted of part-time field and lab testing of concrete and soil compaction for the demolition and renovations to the building.

Allnorth was responsible for review of all testing performed, advising on concrete mix and placement methods, approval of backfill materials, and performing compaction and concrete testing on-site.

Low temperatures during construction phase caused issues with initial curing of the concrete. Extra heaters were brought in, and the areas placed were enclosed during initial curing times. Low temperatures also caused issues with backfill materials and extra measures were taken to cover and heat any soil being backfilled.
