This role requires strong knowledge of construction means and methods, labor and material pricing, cost estimating practices, change order evaluation, and contract documents. The Cost Estimator will work closely with Resident Engineers (REs), construction management staff, contractors, and project stakeholders to develop accurate estimates and support change order negotiations. Responsibilities Review contractor-prepared quantity takeoffs, cost estimates, and supporting documentation for mathematical, technical, and contractual accuracy. Prepare detailed independent cost estimates for proposed contract changes, including labor, materials, equipment, subcontractor costs, productivity factors, and other applicable construction costs. Utilize construction industry-standard estimating software, cost databases, labor productivity manuals, and historical cost information to develop accurate and defensible estimates. Prepare Maximum Allowable Construction Cost (MACC) and Guaranteed Maximum Price (GMP) estimates for alternative project delivery methods, as required. Develop and summarize task and subtask estimates, including quantity takeoffs, labor rates, equipment rates, unit costs, productivity assumptions, and mathematical calculations using appropriate industry-standard factors. Accumulate, evaluate, and document historical construction cost data, construction procedures, and means and methods to maintain current estimating standards and cost databases. Review construction contracts, drawings, specifications, change documentation, and contract modifications to determine scope of work and identify changes impacting project costs. Research current equipment, labor, and material pricing to establish appropriate unit costs and support estimate development. Review contractor daily reports and other construction documentation to evaluate field activities, labor, equipment, and construction methods relevant to cost development. Provide technical guidance to Resident Engineers and construction management staff in the preparation, review, revision, and production of construction cost estimates. Conduct site visits as needed to evaluate existing conditions, understand construction constraints, and assess additional costs or credits associated with changes in the work. Participate in meetings with project stakeholders to review and clarify change order scope, quantities, assumptions, construction methods, and cost impacts. Evaluate contractor change order proposals and provide recommendations to the Resident Engineer regarding cost reasonableness, potential discrepancies, and negotiation strategy. Support the Resident Engineer during contractor negotiations by providing detailed cost analyses, supporting documentation, and technical estimating expertise. Prepare cost estimates, cost analyses, estimate summaries, and other construction records as requested by the Construction Management Manager and/or Resident Engineer.
