Construction Testing & Inspection

CQuest provides construction oversight and materials testing services for a variety of commercial, residential, and public works projects. We work closely with owners, developers, local building officials, engineers, testing laboratories, materials suppliers and contractors to coordinate our inspection services, respond to changing site conditions, and provide effective construction recommendations throughout the duration of the project.  CQuest produces a Daily Inspection Report documenting each day’s activities, and ensures the client is informed of the project’s progress.  CQuest strives to provide the client with not only an inspector, but also a consultant who can offer valuable advice when the need arises.  CQuest’s services and capabilities include the following:
