Quality 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.
The responsibilities and authorities of the various principals in the construction QAQC organization need to be established. These include the Environmental Protection Agency (EPA), the project owner, the engineer of record, the construction manager, and the construction contractors. Included in this assignment of responsibilities is the Construction Managerís quality assurance personnel and the contractorís quality control personnel.
Contractorís that are under consideration to perform the work must submit their construction QAQC plans for review and acceptance. 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.
For any construction activity the EPA requires submittals that conform to regulation and must be approved by the EPA prior to construction.
Field changes for QAQC will be limited to the construction QAQC plan and contractor quality control plan changes. Changes to construction processes or design plans and specifications are governed by the remedial action work plan and design change order procedures.
The project owner, the construction manager, site manager, or construction quality assurance officer may initiate revisions to this construction QAQC plan. It may be revised whenever it becomes apparent that the construction QAQC procedures or controls are inadequate to support work being produced in conformance with the specified quality requirements, or are deemed to be more excessive than required to support work being produced in conformance with the specified quality requirements.
Construction of a process plant is complex undertaking. However, the project owner is well advised to invest in QAQC services in order to prevent poor quality construction that may result in serious project delays and substantial cost over-runs. Process Technical Services has experienced and qualified personnel that are familiar with construction QAQC procedures and are available to establish a construction program for your project, or to provide support for an established construction QAQC project team.
