The Concrete Estimator develops detailed self-perform concrete estimates for water and wastewater treatment facilities, pump stations, tankage, and heavy civil structures across the company’s footprint. This position serves as the estimating team’s technical resource for cast-in-place concrete cost—formwork, reinforcing, placement, and finishing—and carries concrete scope from takeoff through bid day.

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

• Perform detailed quantity takeoffs of cast-in-place concrete structures—mat foundations, walls, elevated slabs, columns, beams, channels, and equipment pads for treatment plants, basins, tanks, pump stations, and vaults.
• Build self-perform concrete estimates from the crew up: formwork contact area, form systems, cycles and reuse; reinforcing; embeds and waterstop; placement and pumping; finishing, curing, and joint work.
• Develop crew sizes, labor productions, and pour sequences; price equipment, form rental or purchase, ready-mix supply, and pumping.
• Carry the cost of liquid-containing structure requirements, including waterstop, joint sealants, leakage testing, crack repair, and coating surface preparation.
• Review Division 03 specifications for mix design, testing, special inspection, hot and cold weather, finish, and tolerance requirements; capture cost impacts and clear assumptions.
• 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.
• 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.
• Other duties as assigned.

• Minimum 5 years of concrete estimating…
