Quality Assurance Testing at the Canyons Development, Lethbridge, Alberta
Tetra Tech provided quality assurance testing to Melcor Developments Ltd. during various phases of construction at the Canyons development in Lethbridge, Alberta, Canada. Tetra Tech provided on-site compaction monitoring and construction management; concrete, asphalt, and laboratory testing; and senior technologist review as required.
Leading up to construction, Tetra Tech was involved in many projects to assist with preparing an outline plan. Our team conducted Phase I environmental site assessments between 2002 and 2007 to determine the general subsurface conditions for the proposed development. Tetra Tech also completed well site reviews, wetland delineation and classification, a wetland compensation plan, pre-disturbance bird surveys, geotechnical evaluation, and slope stability and setback evaluation.
Phase 1 involved a temporary access road, earthworks for a wet pond, underground utilities, and surface works for the super collector roadway and roundabout, as well as a pump station and Phase 1 of the residential subdivision construction.
Tetra Tech was also retained for quality assurance testing during Phase 2 of the residential subdivision. That work included on-site compaction monitoring, as well as surface works such as concrete, aggregate, and asphalt; laboratory testing; and senior review as required.
Tetra Tech also performed compaction monitoring during the construction of Canyon Parkway.
