Core Responsibilities

Primary Functions

Prepare comprehensive, line-item cost estimates for entire construction projects by conducting detailed quantity takeoffs from drawings, specs, and 3D models; include materials, labor, equipment, subcontractor scope, indirect costs, and contingency to produce competitive bids.
Lead end-to-end bid preparation and submission: assemble proposal documents, prepare bid forms, coordinate pricing inputs, validate unit rates, and ensure compliance with contract requirements and client instructions.
Perform takeoffs using paper and digital plans (PDFs, CAD, Revit/BIM) and maintaining strict QA/QC standards to ensure accurate volumes, areas, lengths, and counts for materials and trades.
Solicit, evaluate, and reconcile subcontractor and supplier bids, negotiate scope and pricing, and build a competitive subcontractor lineup while maintaining vendor relationships and historical price databases.
Maintain and update internal cost databases, unit rate libraries, productivity factors, equipment rates, and material prices to reflect market conditions and improve estimate accuracy over time.
Conduct risk identification and quantitative risk analyses for assumptions, schedule impacts, escalating material costs, site conditions, permitting, and site access; recommend contingencies and risk mitigation strategies.
Develop conceptual, budgetary, and detailed estimates across project phases (preliminary, design development, 50%/90% CD, bid-ready), translating design changes into cost impacts and alternatives.
Lead value engineering and constructability reviews—present cost-saving alternatives, recommend system-level changes, and quantify life-cycle and first-cost trade-offs for stakeholders and clients.
Prepare thorough cost summaries, bid tabulations, scope narratives, and proposal executive summaries for leadership and client review, highlighting assumptions, exclusions, and risk allowances.
Coordinate with design and engineering teams to clarify ambiguous drawings, respond to RFIs that impact pricing, and ensure that scope interpretations are consistent across the estimating and project teams.
Develop labor and crew productivity models and apply regional labor rates, prevailing wage adjustments, union requirements, and overtime premiums into labor cost components.
Integrate construction schedule logic with cost data to produce time-phased cash flow projections, manpower loading, and equipment allocation for estimating and early project planning.
Review contract documents, specifications, addenda, and allowances to identify clarifications, omissions, and cost exposures; prepare bidder questions and coordinate addendum pricing adjustments.
Build and present bid strategy recommendations—low-risk/high-profit, selective bidding, or alternative delivery options—and participate in final bid strategy and pricing approvals with executive leadership.
Manage and track estimating deliverables and deadlines in a high-volume environment, prioritize opportunities, and support rapid turnaround bids with consistent quality and audit trails.
Prepare post-bid reconciliation and post-award estimate-to-actual analysis to refine estimating models, capture lessons learned, and improve forecasting accuracy for future projects.
Support procurement and contract negotiation activities by supplying detailed scope breakdowns, cost justifications, and change order pricing during award negotiations.
Perform on-site pre-bid surveys and site visits to assess access, site constraints, existing conditions, and constructability issues; incorporate site-specific cost impacts into the estimate.
Collaborate with sustainability/VDC/BIM teams to incorporate energy-efficiency measures, prefabrication, and modular construction cost differentials into estimates and proposals.
Supervise and mentor junior estimators and estimating assistants—review work, provide estimating methodologies, set standards for takeoff conventions, and ensure consistent application of company estimating practices.
Maintain strict documentation of assumptions, scope inclusions/exclusions, supplier quotes, and version control so estimates are auditable and defendable during negotiations or claims.
Track and analyze historical job costs and change orders to update benchmark rates, adjust contingency practices, and refine risk allowances for future estimates.
Support marketing and client-facing efforts by preparing fee proposals, fee breakdowns, and cost narratives for client presentations and pre-bid meetings.
Ensure compliance with local building codes, permit requirements, bonds, insurance, and contractual constraints that have cost implications for constructability and schedule.

Secondary Functions

Assist preconstruction and project management teams with value engineering workshops and constructability input during design meetings.
Help develop and maintain standardized estimating templates, scope checklists, and bid day processes to accelerate turnaround and reduce rework.
Participate in job start-up meetings to transfer estimating assumptions, baseline costs, and subcontractor commitments into project controls and forecasting.
Support continuous improvement initiatives by documenting estimating processes, identifying automation opportunities, and participating in software/tool evaluations.
Conduct supplier and subcontractor performance reviews and capture preferred-vendor lists for future estimating activities.
Provide ad-hoc analysis for management: bid/no-bid decision support, margin scenario modeling, and sensitivity analysis for major cost drivers.
Assist with quantity verification during construction milestones and participate in claims/change order preparation when estimates are impacted.
Contribute to safety and logistics reviews in the preconstruction phase to identify cost impacts of site safety requirements, staging, and material handling.
Train internal stakeholders on interpreting estimate outputs, assumptions, and the format of cost breakdowns to ensure alignment with project accounting and forecasting.
Maintain confidentiality of bid strategies, pricing models, and supplier agreements in line with company procurement policies.
