Quality Assurance in residential construction projects involves the implementation of a system of processes, procedures and checks to ensure that the project meets all safety, quality and legal standards. It also means ensuring that materials used are up to standard, workers are sufficiently trained and monitored on their workmanship, and client satisfaction is maximized.

Quality Assurance must be implemented from the beginning of the project to its completion, and it should include regular inspections and tests in order to identify any issues that may need to be addressed. Quality Assurance is ultimately important for ensuring a successful construction project that meets all requirements and provides an end product that meets client expectations.
