How QA and QC Work Together to Control Construction Quality



Quality assurance and quality control may sound like the same thing, but they are actually two sides to the same coin. By utilizing different methods, they work to accomplish the same goal. We interviewed ARC’s own QA/QC Manager, Gordon Black, to discuss the differences between quality assurance and quality control and how companies can benefit from having both programs. Keep reading to learn more from Gordon.


What is QA and QC?

“Every person will not have the same definition for quality assurance and quality control,” says Black. “However, one way to look at it is that quality control is on the frontlines while quality assurance is working behind the scenes.” Quality control inspectors are overseeing the shipping and receiving, filler materials, products and other onsite elements. Meanwhile, quality assurance managers ensure that the proper procedures are being followed. In general, a quality control role works with fossil programs while quality assurance with nuclear.


Why Do Companies Need Both?

Black believes that having both a quality assurance and quality control team offers a unique form of checks and balances. Both roles can look over the other to ensure that the proper procedures are being carried out. For example, if a quality control person writes a procedure, the quality assurance manager will be working behind him to verify that the information meets code requirements and customer specifications. Though they are in two separate fields within the industry, they should work hand in hand to assure that each team is doing the right thing and providing clients with five-star service.


How Does ARC’s Quality Programs Benefit Clients?

Instead of being limited by one program, offering two widens ARC’s abilities. “We are not limited to only fossils, pressure vessels and manufacturing parts but can also conduct repairs on nuclear vessels,” says Black. By providing both quality assurance and quality control, ARC can serve our clients more efficiently and effectively. It also allows us to constantly evolve and find better methods and ways to complete projects. Nuclear programs require much more documentation than fossil programs. However, we can take what we have learned from the detailed nuclear documentations and apply it to fossil programs to help it grow and improve. If code permits and clients approve, incorporating new elements to your program can help your program constantly improve.


ARC is committed to upholding the highest standards for its quality programs. This assures clients that the safety and quality of its wielding and fabrication will be produced in excellent conditions. To assure clients of our safe, quality work, we have received the following certifications from the American Society of Mechanical Engineers (ASME):


  • R - Metallic repairs and alterations at Shop & Field Locations

  • S - Design, fabrication, assembly, and inspection of boiler and pressure vessel components of Power Boilers

  • U - Fabricate and assemble pressure vessels in both the field and in-shop applications

  • NR - Nuclear Components Repair / Replacement

  • NB - National Board
