Core Responsibilities

Primary Functions

Prepare detailed, itemized quantity takeoffs from drawings and specifications using Bluebeam, PlanSwift, Revit/BIM, or similar tools, ensuring accuracy of materials, labor, equipment, and subcontractor scopes for medium- to large-scale construction projects.
Develop complete cost estimates and bid packages including line-item budgets, unit pricing, labor productivity assumptions, equipment rates, material takeoffs, and subcontractor quotations to support competitive and profitable proposals.
Review project design documents, specifications, and addenda to identify scope gaps, exclusions, value engineering opportunities, and potential cost and schedule risks; document clarifications and request information (RFI) as needed.
Solicit, analyze, and negotiate scope, pricing, and terms with subcontractors and vendors; evaluate multiple bids, create fair bid comparisons, and recommend award decisions aligned with project goals and risk tolerance.
Prepare and deliver formal bid submissions and proposal narratives, including assumptions, contingencies, clarifications, schedule impacts, and contractual qualifications to support final pricing and owner negotiations.
Maintain and refine historical cost databases, unit cost libraries, productivity factors, and vendor pricing catalogs (RSMeans, internal databases) to improve estimate accuracy and shorten turnaround times.
Collaborate with project management, design, procurement, and operations teams during preconstruction to develop constructability reviews, phasing plans, and life-cycle cost analyses that reduce cost and schedule risk.
Perform value engineering sessions with clients, architects, and subcontractors to identify cost-saving alternatives, material substitutions, and sequence adjustments that preserve design intent while improving budget outcomes.
Evaluate contract documents and site conditions to determine necessary allowances, escalation, bonding, insurance, and subcontractor contingency amounts; incorporate these into the final bid and risk register.
Lead or assist with pre-bid client meetings, site visits, and preconstruction workshops to gather clarifications, establish client expectations, and confirm site logistics that affect cost and schedule.
Create and maintain estimate backup documentation, bid logs, takeoff files, and cost reconciliations that support auditability and handoff to project accounting for budget setup and change management.
Model project cost scenarios and sensitivity analyses to show budget impact of scope options, schedule changes, or material price fluctuations; present findings to stakeholders to inform decisions.
Ensure all estimates conform to company estimating standards, formatting, markup policies, and approval thresholds while delivering consistent and defensible pricing across portfolios.
Coordinate with scheduling teams to align cost assumptions with realistic work sequencing and labor-resource allocations, ensuring cost-schedule integration for reliable forecasting.
Monitor market conditions, commodity pricing trends, labor availability, and regulatory changes that affect cost estimates; proactively adjust assumptions and communicate impacts to leadership and clients.
Support post-bid negotiations and contract award processes by providing cost rationales, scope clarifications, and revised pricing for negotiated contract forms or changes in client requirements.
Assist in preparing estimates for change orders, claim defenses, and recovery schedules by quantifying labor, material, and equipment impacts in a way that supports contractual positions.
Train and mentor junior estimators and cross-functional team members on takeoff techniques, estimating software workflows, cost library usage, and best-practice documentation to elevate team capability.
Participate in continuous improvement initiatives to standardize estimating templates, automate repetitive tasks with Excel macros or scripts, and implement estimating software integrations to increase speed and accuracy.
Track bid results and post-bid performance metrics to identify estimating variances, win/loss patterns, and opportunities to refine pricing strategies and competitive positioning.
Prepare executive-level bid summaries, risk matrices, and margin analyses that support go/no-go decisions and align bids with corporate financial objectives.
Provide on-call support during project close-out or claim resolution periods to supply original estimate backup and clarify basis of estimate for disputes or reconciliation activities.

Secondary Functions

Assist with procurement support by preparing scopes of work for RFP/RFQ packages and participating in vendor selection evaluations.
Support ad-hoc reporting requests for finance or operations that require historic estimate comparisons, contingency usage, or cost trend analysis.
Contribute to the organization's estimating standards, templates, and knowledge base to ensure consistent practices across regions and project types.
Collaborate with business development and proposal teams to develop conceptual budgets and pricing strategies during pursuit phases.
Participate in cross-functional meetings to translate estimating assumptions into contract deliverables, procurement plans, and schedule milestones.
Provide technical support for estimating software rollouts, updates, and user training sessions.
