Candidates with estimating experience beyond concrete and the ability to lead complete bids will be given strong consideration.

- Solicit and level subcontractor and supplier pricing for rebar fabrication and placement, ready-mix, pumping, post-tensioning, precast, shotcrete, and testing; confirm scope alignment.
- Identify risks and opportunities, including access and crane reach, pour breaks, dewatering interfaces, winter concrete, schedule constraints, and design ambiguities; prepare RFIs during bid.
- Maintain a concrete cost and productivity database; track estimate performance against job cost results and field feedback.
- Participate in bid reviews and turnover meetings; support the bid-to-execution transition, budgeting, and buyout.
- Bid Leadership & Multi-Discipline Estimating:
- Lead complete bids as lead estimator: bid schedule, scope assignments, bid forms, addenda, and proposal compliance.
- Estimate additional self-perform scopes such as earthwork, yard piping, process mechanical, and site utilities.
- Develop general conditions, markups, and bid-day strategy with leadership.
- Mentor junior estimators and share concrete estimating best practices across offices.
