Quality Assurance and Quality Control Programs: Inspection Plans, Testing Protocols, Mock-Ups, Pre-Installation Conferences, and Standards

The parallel QA and QC systems that govern construction quality, how inspection plans and testing protocols are structured and enforced, and the architect's role in evaluating compliance through mock-ups, pre-installation conferences, and quality standards verification.

ARE · Construction & Evaluation

Overview

Quality on a construction project doesn't happen by accident. It happens because someone designed a system to check the work, defined what acceptable looks like before construction started, and then verified that the installed work actually meets that standard. That three-part process is what quality assurance and quality control programs are built to deliver.

The terminology trips people up, so let's be precise. Quality control (QC) is what the contractor does internally to ensure their own work meets the contract requirements. The contractor is responsible for it. Quality assurance (QA) is what the owner's team, including the architect, does to verify that the contractor's QC is actually working. The architect evaluates; the contractor controls.

This distinction matters enormously for the ARE. Questions will present scenarios where you must determine whether a quality-related action belongs to the contractor's QC program or the architect's QA role. Conflating the two is a common and costly mistake in professional practice.

The tools that make quality programs effective span a range of sophistication. Inspection plans set out when and how work will be checked. Testing protocols define the quantitative benchmarks that work must meet. Mock-ups establish the physical standard of quality before production runs. Pre-installation conferences align everyone on expectations before work begins. Each tool addresses a different failure mode in the quality chain.

For NCARB Objective 2.2, you need to analyze how these tools work in practice, evaluate whether a quality program is adequate for a given scope of work, and understand where the architect's coordination role fits relative to the contractor's self-inspection obligation.

Essential

The QA/QC Distinction in Construction The Army Corps of Engineers formalized the contractor quality control (CQC) system model that much of the construction industry has adopted in some form. Under this model, the contractor operates a three-phase inspection system covering preparatory, initial, and follow-up checks. The owner's quality assurance team then monitors the contractor's CQC activities rather than performing primary inspection themselves. For ARE purposes, the critical distinction is ownership of each function: - Contractor QC: The contractor is obligated to inspect their own work. AIA A201-2017 Section 3.5 requires work to conform to the contract documents. The contractor cannot fulfill this without internal quality checks. - Architect/Owner QA: The architect's periodic site observations, the testing lab's reports, and special inspectors' findings are all QA functions. They verify whether the contractor's QC is actually catching and preventing problems.

Professional

An architect working on a 200,000-square-foot office building has just received notification that the curtain wall installation is scheduled to begin in three weeks. The curtain wall specification requires a pre-installation conference before any installation begins, a mock-up panel at a designated grid location that must pass AAMA 502 field testing before production commences, and continuous special inspection by a qualified glazing inspector during all installation work. A competent architect administering this project doesn't wait for the contractor to schedule the pre-installation conference. They verify the conference is scheduled, confirm that the curtain wall manufacturer's technical representative will attend, review the specification requirements in advance so the discussion covers everything required, and generate meeting minutes afterward that document every commitment made by every party. If the contractor shows up without their shop drawings approved, that's documented in the minutes as an open item.

TLDR

QC is contractor self-inspection; QA is owner-side verification. The contractor can't rely on the architect to catch their deficiencies.
The Statement of Special Inspections (SSI) submitted to the AHJ before construction governs required special inspection scope and frequency.
IBC Chapter 17 lists which work requires special inspection: concrete, structural steel, masonry, soils, SFRM, seismic systems.
Mock-ups establish the physical quality standard before production begins; once approved in writing, they become the binding reference.
Pre-installation conferences happen before critical work begins; they align all parties on scope, sequence, interfaces, and quality requirements.
Meeting minutes from pre-installation conferences are part of the project record and document communicated requirements.
Test payment default: owner pays for required testing; contractor pays for retesting when initial tests reveal non-conformance.
Referenced standards (ACI 117, AWS D1.1, AAMA 502) define tolerances. Work within tolerance = conforming, even if imperfect-looking.

ELI5

Think about a restaurant with two quality systems running at the same time. The kitchen has its own quality control. The chef tastes the food before it goes out. The sous chef checks the temperature. The line cook inspects the plating. That's the kitchen's internal system to make sure their own work is good before it leaves. Then the restaurant has a health inspector who shows up periodically, checks the kitchen records, takes temperature readings, and verifies that the kitchen's internal quality control is actually working. That's external quality assurance. Construction works the same way. The contractor runs their own quality control program. Before they pour concrete, they check the forms and rebar. During the pour, they test the concrete. After, they cure it properly. That's all contractor QC. The architect, special inspectors, and testing lab run the owner's quality assurance program.
