How To Build A Construction Quality Control Plan That Prevents Rework
A construction quality control plan is the cheapest insurance a GC can buy against rework. After all, few things eat into a job’s profit faster than tearing out work your crews already installed.
You can’t control every design error or every sub’s workmanship. However, you can control when problems get caught, who catches them, and how fast they get fixed.
So, what is a construction quality control plan? A construction quality control plan is a written process that defines the quality standards for a project, the inspections and tests that verify the work, who is responsible for each check, and how deficiencies get documented and corrected. In other words, it’s how you make sure work meets the contract, the specs, and the code the first time, before it’s covered up.
Understanding construction quality control
Quality assurance vs. quality control in construction
People often use QA and QC interchangeably, but they do different jobs. In short, quality assurance prevents defects, and quality control finds them.
| Quality assurance (QA) | Quality control (QC) | |
|---|---|---|
| Focus | The process | The work |
| Timing | Before and during the work | During and after the work |
| Goal | Prevent defects | Find and fix defects |
| Construction examples | Submittal reviews, mockups, preconstruction meetings, training | Inspections, testing, punch lists, deficiency tracking |
| Typical owner | Project manager or quality manager | Superintendent, foremen, and QC inspectors |
Which comes first, QA or QC? QA comes first, because it sets the standards QC checks against. For example, approving a submittal is QA. Then, verifying that the installed product matches that submittal is QC.
Can QA and QC be the same person? On smaller jobs, yes. Often, the superintendent wears both hats. On larger jobs, however, it helps to separate them, so the person checking the work isn’t the same person under pressure to finish it.
A strong QA/QC program in construction needs both. That’s why your construction quality control plan should cover prevention and inspection, not just a final walkthrough.
What goes in a construction quality control plan
Every construction quality control plan should cover six things:
- Quality standards: the contract, specs, drawings, building codes, and manufacturer installation requirements.
- Roles and responsibilities: who owns quality for the GC, for each sub, and for any third-party inspector.
- An inspection and test plan: which inspections and tests happen, when, and who signs off.
- Checklists by scope: so every super and every crew checks the same things the same way.
- Documentation requirements: how you record inspections, deficiencies, photos, and corrections.
- Corrective action procedures: how you assign, track, and verify every fix.
The need: what rework really costs GCs
Rework isn’t a rounding error. According to FMI and PlanGrid’s Construction Disconnected report, rework cost the U.S. construction industry about $65 billion in 2018. Nearly half of it, 48%, traced back to poor project data and miscommunication rather than bad workmanship. Specifically, poor communication accounted for 26% and poor project data for 22%.
In other words, much of your rework starts in the office, not the field. Someone built from an old drawing, missed an RFI response, or never saw the approved submittal.
Here’s what that means on a single job. Suppose you’re running a $10 million project with a 5% profit margin, which is $500,000 in profit. If rework eats 3% of the contract value, the math looks like this:
$10,000,000 × 3% = $300,000 in rework
$300,000 ÷ $500,000 = 60% of your profit gone
That’s a worked example, but the takeaway holds on any job. Because margins are thin, even a little rework takes a big bite out of profit. That’s why a construction quality control plan pays for itself on the first job.
Where quality control breaks down
Without a construction quality control plan, problems usually show up in four places.
Relying on the final inspection
If the first real quality check happens at the punch walk, every defect is already covered up, finished, and expensive to fix.
Building from outdated documents
When the field works from an old drawing set, crews install work that’s wrong on day one. Consequently, you pay for it twice.
Deficiencies nobody closes
An item fails, someone says the sub will handle it, and three weeks later it’s still open. Meanwhile, the next trade has already covered it.
Subs with no quality plan of their own
If the subcontract doesn’t require sub-level QC, you end up inspecting everything yourself.
The solution: how to build a construction quality control plan that prevents rework
Step 1: Set standards in preconstruction
Start with the contract, specs, drawings, and code. Then, run constructability reviews and resolve conflicts before crews mobilize. Also, flag long-lead and high-risk items during construction procurement, so submittals get reviewed before anything gets ordered.
Step 2: Build an inspection and test plan
An inspection and test plan (ITP) lists every inspection and test by scope of work, when it happens, and who has to sign off. The most important entries are hold points, where work can’t continue until someone signs off, and witness points, where a party gets the chance to observe.
Here’s a simple ITP example for a slab on grade:
| Stage | Inspection or test | Type | Who signs off |
|---|---|---|---|
| Before the pour | Subgrade, vapor barrier, and rebar placement | Hold point | Superintendent and special inspector |
| Before the pour | Embeds, sleeves, and MEP rough-in | Hold point | Superintendent and MEP foremen |
| During placement | Slump tests and test cylinders | Witness point | Testing agency |
| After the pour | Curing, flatness, and cylinder breaks | Review | Superintendent and engineer of record |
Many GCs also use a three-phase approach for each definable feature of work: a preparatory meeting before work starts, an initial inspection when the first work is in place, and follow-up inspections until the work is complete. If you work on federal projects, you’ll recognize it as the three-phase control system required on U.S. Army Corps of Engineers jobs.
Step 3: Standardize checklists
Build checklists for your most common scopes, like concrete, framing, MEP rough-in, and finishes. Then, use them on every job, so quality doesn’t depend on who’s running the site. For the digital side, here’s what to look for in construction inspection software.
Step 4: Put sub QC in the subcontract
Require each sub to follow your quality plan, attend preparatory meetings, and fix deficiencies by a set deadline. Also, use mockups or first-work inspections for high-risk scopes, so everyone agrees on what “done right” looks like before production starts.
Step 5: Document everything, and close the loop
Record every inspection, deficiency, and correction with photos. Then, assign each deficiency to a specific person with a due date, and verify the fix before the next trade covers it. Construction photo documentation gives you proof the work was right, and construction field reporting gets the results to the office the same day.
Step 6: Fix the communication gaps behind rework
Since nearly half of rework starts with poor data and miscommunication, quality control depends on everyone working from current documents. Specifically, make sure answered RFIs and approved submittals reach the field right away. When they don’t, here’s how submittals lead to change orders. Better communication between project managers and superintendents closes the rest of the gap.
Step 7: Review quality before every milestone
Don’t wait for the punch walk. Instead, run quality reviews before each major milestone, like dry-in, before drywall, and before ceilings close. That way, a smaller punch list makes project closeout faster.
However, running all of this on paper and spreadsheets across multiple jobs is where most construction quality management programs fall apart. Checklists live in binders, photos live on phones, and deficiencies live in someone’s notebook. That’s why more GCs manage quality control in construction management software instead, where inspections, photos, RFIs, and documents live with the project they belong to.
Why GCs manage construction quality control in RedTeam
RedTeam is construction management software built for general contractors, by people who came from the jobsite. For over 20 years, small to mid-sized GCs have used RedTeam to simplify, automate, and standardize their work from precon through closeout. As a result, your construction quality control plan becomes part of how the job runs, not a separate binder.
With RedTeam, your team can:
- Keep the field on current documents, with drawings, RFIs, and project documents in one place.
- Track RFIs with a full audit trail, so answers reach the people building the work.
- Document conditions and fixes as they happen, using daily logs and jobsite photos.
- Connect quality issues to cost and schedule, with change orders and budgets in the same platform.
- Give the field and office the same information, so nobody builds from yesterday’s plan.
Unlike enterprise construction software, every RedTeam customer gets full software functionality and a dedicated implementation and customer success team. In other words, you’re not just buying a login. Instead, you get a team that helps you set up your quality workflows the way your company runs.
Ultimately, the GCs with the best margins aren’t the ones who fix rework fastest. They’re the ones who prevent it in the first place. Compare your options in our guide to the best construction management software.
That’s total project control. That’s RedTeam.
