Core Responsibilities

Primary Functions

Prepare comprehensive, line-item cost estimates and detailed quantity takeoffs from architectural, structural, mechanical, electrical, and civil drawings; translate design intent and specifications into accurate material and labor quantities for lump-sum, unit-price, and GMP bids.
Develop and maintain project cost models and estimate databases that include unit rates, labor productivity, material costs, equipment rates, and subcontractor allowances to ensure consistency and defensibility across projects.
Produce complete bid packages, including detailed scope narratives, bid forms, assumptions, exclusions, contingency recommendations, and value engineering alternatives to support competitive and profitable submissions.
Coordinate, solicit, and evaluate subcontractor and supplier bids; issue scopes of work and RFIs to clarify pricing items, compare multiple proposals, and recommend preferred subcontractors based on cost, schedule, and capacity.
Conduct risk assessments and contingency analysis for estimates; quantify project-level risks, identify high-exposure line items, and recommend mitigation strategies that preserve margin and schedule integrity.
Perform constructability reviews with design, operations, and field teams to identify cost-saving opportunities, sequence impacts, and potential scope conflicts; revise estimates to reflect constructability outcomes.
Execute life-cycle cost analysis and long-term maintenance cost forecasting to support owner decision-making on systems selection, materials, and design alternatives.
Lead value engineering studies to analyze alternate materials, systems, and methods that reduce cost without sacrificing quality or performance; present quantified savings and implications to stakeholders.
Maintain and update historical cost databases and lessons-learned logs to improve estimating accuracy and predictability across future projects and portfolios.
Prepare and present written and verbal estimate summaries, cost trend reports, margin analysis, and board-level bid recommendations to senior leadership and project stakeholders.
Work closely with procurement and contracts teams to convert estimates into purchase orders, contract budgets, and subcontract scopes, ensuring alignment between estimated assumptions and contract language.
Reconcile estimate budgets with project accounting during preconstruction turnover and provide budget baseline inputs for project controls, scheduling, and forecasting systems.
Develop labor and productivity models based on crew mixes, regional labor rates, union vs. open-shop impacts, and site logistics; apply productivity factors and escalation to create realistic labor cost projections.
Monitor market pricing trends for materials, equipment, and subcontractor availability; proactively adjust unit rates and vendor lists to reflect current market conditions and supply-chain constraints.
Support bid/no-bid decisions by analyzing competitive landscape, margin targets, risk profile, and strategic fit; produce scenario-based profitability analyses and recommendation memos.
Produce layered estimates (conceptual, schematic, design development, and final) at different design phases that refine cost certainty as design matures and serve as inputs to owners and designers.
Manage and mentor junior estimators and takeoff technicians, reviewing their work for accuracy, completeness, and adherence to estimating standards and templates.
Track and manage changes to scope and quantify the cost impact of design revisions, change orders, and potential claims during preconstruction and early construction phases.
Integrate BIM/VDC deliverables and 3D model takeoffs into the estimating workflow where applicable, coordinating with VDC specialists to extract accurate quantities and reduce manual takeoff risk.
Prepare material and equipment procurement timing plans and cash-flow forecasts for bids and contract negotiations, including staged purchasing recommendations to mitigate price volatility.
Ensure estimates comply with contract documents, building codes, regulatory requirements, and owner-specific standards; flag non-conforming items and recommend corrective scope adjustments.
Maintain quality control and versioning for estimate files, assumptions registers, and backup documentation to support auditability and post-bid review.
Facilitate pre-bid and pre-proposal meetings, site visits, and bidder conferences; document clarifications and issue timely addenda or estimate updates.
Collaborate with estimating technology and IT teams to implement and optimize estimating software, templates, and macros that increase efficiency and reduce human error.

Secondary Functions

Support ad-hoc cost analysis requests from business development, finance, and operations teams, including quick-turn conceptual estimates for proposals and RFIs.
Contribute to the continuous improvement of the organization’s estimating practices, standards, templates, and unit-rate libraries to drive consistency and higher win rates.
Collaborate with design and engineering teams to translate emerging design options into cost implications during value-based decision cycles.
Participate in cross-functional preconstruction workshops and sprint-style estimating sessions to accelerate bid delivery while preserving accuracy.
Assist in the rollout, training, and administration of estimating software (e.g., Sage Estimating, CostX, ProEst, On-Screen Takeoff) and integration with ERP or project controls platforms.
Conduct post-bid and post-project estimate-to-actual analysis to identify variance drivers and update estimating assumptions and rates accordingly.
Support claims, disputes, and change management by preparing historical estimate comparisons, documented assumptions, and justification for cost impacts.
Maintain relationships with trade partners, suppliers, and subcontractors to secure pricing transparency, early buyout opportunities, and priority scheduling.
Engage in company safety and quality initiatives to ensure estimates appropriately reflect required safety staging, temp works, and QA/QC activities.
Participate in talent development by creating training materials, delivering workshops, and establishing checklists for junior estimating staff.
