Estimating: The Art, the Science, and the Risk Margin Contractors Miss

Estimating isn't just math—it's how contractors decide which risks they're willing to own. In this episode of the Construction Genius Podcast, Eric Anderton talks with Chris Clausing, Director of Program and Curriculum Innovation for Construction at Colibri Group, about why estimating is still more art than science—and why contractors consistently miss the risk margin that protects profit. Drawing on 25 years as a commercial general contractor, Chris explains how regional differences, niche discipline, poor handoffs, and earned value blind spots quietly erode margins. They also discuss how AI can help identify estimating risks—if it's adopted thoughtfully. If you've ever won work that you later wished you hadn't, this episode will change how you think about estimating.
