At OLIVER HATCHER CONSTRUCTION, I led preconstruction estimating for complex commercial projects valued up to $126 million. I developed conceptual budgets, detailed estimates, and competitive proposals.

At ALRIG USA, I developed cost plans and proposals for national commercial and retail projects. My value-engineering alternatives generated 3–5% cost savings while preserving project requirements and quality expectations.

At SUPERIOR CONTRACTING, I developed commercial and light-industrial estimates and supported early preconstruction with conceptual budgets and progressive estimate refinement.

Earlier, at SORENSON GROSS CONSTRUCTION, I supported senior estimators on commercial, municipal, educational, and healthcare projects. I used Bluebeam Revu and PlanSwift for digital takeoffs, drawing analysis, and estimate preparation.
