QAQC Onsite Inspections

QAQC Onsite Inspections


Quality Control and Quality Assurance (QA/QC) onsite inspections are critical and ensure that systems and applications of materials of during construction are safe, built to code, and will last for generations to come. Quality Control (QC) inspections are typically completed on behalf of the contractor and similarly Quality Assurance (QA) inspections are done on the owner’s behalf with the sole purpose and goal to ensure the quality of work and materials used meet the required contract documents and specifications, as well as the owner’s expectations at construction completion.

As part of Cambium’s construction monitoring services, our qualified inspectors provide QA/QC onsite inspections to ensure that all components of the project are built to appropriate specifications. Cambium is the largest, independent inspections company in Eastern Ontario and our team has extensive experience completing construction inspections in a number of different areas, combining extensive training and expertise to ensure that building quality into the project from the start to avoid costly changes or delays.
