Weston Solutions is seeking a Chief Estimator, Construction and Environmental Services to lead and mature the company’s estimating and preconstruction discipline across commercial, federal, civil, infrastructure, environmental remediation, and design-build pursuits, with project values ranging from approximately $1MM to $200MM. This role will serve as the senior technical authority for estimating while helping build the early preconstruction capabilities needed to improve scope definition, constructability review, procurement strategy, risk planning, value alternatives, and bid-to-execution handoff.
The Chief Estimator will own estimate strategy for major, complex, and high-risk opportunities; establish scalable standards, tools, templates, and review gates; lead development and review of ROM, conceptual, parametric, budgetary, detailed, and final proposal estimates; and validate estimate assumptions, subcontractor and vendor pricing, production rates, escalation, indirect costs, contingencies, and risk allowances. The role will work closely with Operations, Capture, Proposal Development, Procurement, Project Management, technical teams, environmental professionals, safety, quality, scheduling, and executive reviewers to ensure estimates are complete, compliant, defensible, risk-informed, and aligned with the proposed execution approach.
Location: Remote
Expected Outcomes:
- Lead Weston’s estimating and preconstruction discipline across commercial, federal, civil, infrastructure, environmental, and design-build pursuits.
- Own estimate strategy for major, complex, and high-risk opportunities, aligning scope, cost, schedule, procurement, risk, and execution approach.
- Establish scalable estimating standards, tools, templates, review gates, and governance based on project value, complexity, and risk profile.
- Lead development and review of ROM, conceptual, parametric, budgetary, detailed, and final proposal estimates.
- Validate assumptions, quantities, production rates, labor, equipment, materials, escalation, indirect costs, contingencies, and risk allowances.
- Review subcontractor and vendor pricing for completeness, reasonableness, exclusions, qualifications, coverage, and commercial risk.
- Partner with procurement to develop sourcing strategies, bid packages, quote-leveling tools, subcontractor coverage plans, and buyout assumptions.
- Identify scope gaps, overlaps, alternates, allowances, constructability issues, sequencing constraints, logistics risks, and execution exposures before submission.
- Develop/train estimators in scope ownership, technical estimating, benchmarking, subcontractor evaluation, basis-of-estimate documentation, and executive-ready estimate presentation.
- Improve bid-to-execution transition by converting estimate assumptions, risks, procurement plans, and scope decisions into actionable guidance for operations and project delivery teams.
- Support strategy development and market research by gathering competitive intelligence, analyzing market pricing trends, identifying subcontractor and vendor capacity, bid optimization and informing pursuit positioning, go/no-go decisions, pricing strategy, and long-term estimating priorities.
