Quality management is a top priority, but inconsistent standards are draining profit

New research shows inconsistent QA/QC standards are eroding margins, driving rework, and fueling disputes across construction projects. A total of 811 qualified professionals who directly perform or oversee QA/QC from 13 countries participated, revealing how fragmented processes reduce visibility and push costs into the shadows—triggering rework, schedule slippage, disputes, and warranty exposure.

Key findings:

77% report inconsistent QA/QC documentation processes, with 56% citing “different standards across sites and trades” as their biggest challenge.
Nearly 2 in 3 companies with consistent QA/QC processes keep rework costs under 5% of budget, compared to just 1 in 3 without standards.
Companies with consistent QA/QC are 28% more likely to achieve margins above 3%.
Teams with no set QA/QC standard face 50% higher warranty exposure and are 23% more likely to experience subcontractor disputes.
78% believe stronger QA/QC would improve margins, underscoring that consistency is not just a compliance goal but a profit strategy.
