Construction QA/QC

4Quality control during the construction process is extremely important in order to safeguard the value of the owner's investment. Process Technical Services QAQC personnel can perform checks and tests throughout the construction process, providing the project owner assurance that the project is being built according to specifications.

The first step in establishing the requirement for construction QAQC is to develop an overview of the entire quality program. A quality management plan is essential and the form of the construction organization needs to be established.

These include the project owner, the engineer of record, the construction manager, and the construction contractors.

The construction manager will maintain all submittal files via a combination of a secure document filing and storage system, and a computerized document tracking system.

General construction inspection and verification requirements include inspections, QC testing, QA testing, establishing construction acceptance criteria, construction audits, compliance with handling, storage, packaging, preservation, and delivery requirements, and material identification and traceability.

Inspections will uncover construction deficiencies. These will need to be identified, reported and corrective and preventive action taken.

Document handling and retention procedures are important. Records must be updated on a daily basis and a daily construction report issued. The construction QAQC plan requires that all construction drawings be stored and that As-Built drawings be prepared and reviewed.
