Search resourcesContractors are investing in AI for estimating and precon, but most use is still shallow. A sourced look at where engineered AI fits document overload, leveling, and risk review.
Most projects overrun the original estimate. How to measure cost variance, where overruns come from by trade and phase, and how GCs tighten the feedback loop from bid to closeout.
Public bid tabulations show low-to-high spreads often in the teens to tens of percent. How bidder count, project size, and delivery method shape the gap, and how GCs should use spread as a health check on coverage and carry.
Bid leveling and scope assembly dominate precon hours (often 40-50 hours of leveling and 30-40 hours of MEP scope work per project), leaving little capacity for judgment. A synthesized view of where the time goes.
