Cost of Rework in Construction 2026: Industry Data and Cross-Sector Context
Updated June 2026
How much does rework cost in construction?
Direct field rework averages about 5% of total project cost, per the Construction Industry Institute's 144-project IR-153 dataset, rising to a 90th-percentile of 12.4% on the worst projects. Once indirect costs and latent defects are counted, the UK Get It Right Initiative puts total avoidable-error cost as high as ~21% of project value (a 10-25% range).

Note on focus
This site focuses primarily on software engineering rework. This page provides construction industry context. For the primary software content, see the software page.
Construction rework has been studied extensively by civil engineering researchers in the US (the Construction Industry Institute at the University of Texas), the UK (the Get It Right Initiative), and Australia (Love and colleagues). The figures are surprisingly consistent with software: direct field rework averages around 5% of project cost, rising past 12% on the worst projects, and UK studies that count indirect costs and latent defects put the total as high as 21%.
The parallel with software rework is instructive. Construction rework's most expensive source is design changes that propagate into physical work already completed -- the construction equivalent of a requirements change after implementation has started. The 1-10-100 rule applies: a change to a building's structural design costs less in the design phase than after concrete has been poured.

Root Causes in Construction vs. Software
| Root Cause | Construction | Software Equivalent |
|---|---|---|
| Design errors | Structural errors, clash detection misses | Requirements defects, architecture errors |
| Design changes | Client-driven scope changes after work begins | Requirement changes after implementation starts |
| Coordination failures | Subcontractor interface errors | API contract failures between teams |
| Unclear specifications | Ambiguous drawings, missing tolerances | Ambiguous acceptance criteria |
| Quality control failures | Work not inspected before it is covered | Code merged without review or tests |
The parallel is exact: both industries find that unclear specifications and coordination failures are the primary rework drivers. The cost-of-change curve applies in both: a structural change in design costs 1x; the same change after the building is partially constructed costs 100x. The IBM 1-10-100 rule was not invented for software -- it was already well-understood in engineering and manufacturing before Boehm applied it to code.
The key difference: construction rework is highly visible (you can see the torn-out wall). Software rework is invisible in sprint velocity metrics. This invisibility is one reason software rework is systematically underestimated and underreported relative to construction.
