ML-Powered Estimation via StruxBIM™

Our ML models are trained on 10,000+ historical steel fabrication projects. They predict material cost, labor hours, and total project cost from your structural model — with confidence intervals that shrink as the design is refined.

Estimation & Takeoff

Predictive AI Cost Estimation from Your Structural Model

Zenith's ML-powered estimation service delivers accurate cost forecasts before a single shop drawing is issued. We run your structural model through StruxBIM™'s estimation engine — accounting for section weight, connection complexity, regional labor rates, and current market pricing — and return a complete BOM and cost report in hours, not days.

Unlike manual takeoff, our AI scores every connection for fabrication complexity, flags unusual details that drive up cost, and runs change order impact analysis in seconds when scope changes.
