The Common Scenario
You finish a job. The builder calls two weeks later — there's water pooling where it shouldn't. Now you’re sending a crew back, replacing materials, and absorbing costs no one quoted for.
The QS Insight
From a Quantity Surveyor’s view, rework isn’t just a site issue — it's a margin killer. Labour, materials, call-backs, fuel, and even the opportunity cost of missing new work all stack up. Most companies don’t track these "silent costs", but they chip away at your yearly profit.
