Quality Control and Assurance – Quality refers to the project requirements established by the contract documents. There is not “low quality” or “high quality;” there are simply lesser or greater requirements.

Our quality control is based on the belief that:

• Quality control should ensure that the work is done correctly the first time.
• Quality is achieved by focusing on preventing problems or errors rather than reacting to them.
• Quality is achieved by qualified individuals performing all work functions.
• Quality is achieved by providing proper training of personnel and ensuring that all personnel remains current on the knowledge and skills needed for their position.
• Quality is controlled by adequate planning, coordination, supervision, and technical direction, proper definition and a clear understanding of job requirements and procedures, and the use of appropriately skilled personnel.
• Quality is verified through checking, reviewing, and monitoring of work activities, with documentation by experienced, qualified individuals who are not directly responsible for performing the work.

A quality process must adhere to three basic principles:

• Prevent errors from being introduced, by creating a project-specific material and installation protocol.
• Implement checking and back-checking procedures throughout all phases of work.
• Utilizing quality control services as hands-on training for specific projects and products.
