and engineer's estimates for major transportation and transit capital projects.Prepare construction cost estimates throughout design development, including conceptual, 30%, 60%, 90%, 100%, bid, and construction-phase estimates.Develop detailed estimates from design criteria, drawings, specifications, quantity takeoffs, technical reports, site conditions, construction phasing, and other project information.Prepare estimates across multiple transportation disciplines, including civil/site work, structures, stations and facilities, track, utilities, traction power, train control/signals, communications, and MEP systems.Perform detailed quantity takeoffs and develop unit-price analyses incorporating labor, equipment, materials, productivity, subcontractor pricing, indirect costs, and applicable markups.Develop comprehensive Basis of Estimate (BOE) documentation clearly identifying estimate methodology, scope, assumptions, exclusions, qualifications, pricing sources, escalation, contingency, and risk provisions.Develop total construction cost estimates incorporating direct and indirect construction costs, allowances, escalation, contingency, provisional sums, risk provisions, and other applicable project costs.Establish and maintain estimating structures aligned with the project's Work Breakdown Structure (WBS), cost breakdown structure, bid packages, and contract strategy.Engineer's Estimates & Independent Cost EstimatesPrepare and validate engineer's estimates to support construction procurement and bid evaluation.Prepare detailed Independent Cost Estimates (ICEs) for construction changes, change orders, contract modifications, amendments, and other commercial actions.Evaluate contractor and consultant estimates for completeness, reasonableness, quantities, labor productivity, equipment, materials, subcontractor pricing, overhead, markups, and alignment with project scope.Develop independent pricing positions and recommendations to support project management and senior leadership.Establish appropriate pricing thresholds and identify significant deviations from anticipated market pricing.Estimate Review, Validation & ReconciliationIndependently review estimates prepared by designers, consultants, contractors, and third-party estimators.Evaluate estimates for scope completeness, quantities, unit rates, constructability assumptions, escalation, contingency, risk, market conditions, and consistency with design maturity.Lead and participate in estimate validation and reconciliation workshops with project teams, designers, construction managers, consultants, and other stakeholders.Reconcile differences between independent estimates, consultant estimates, contractor pricing, and project budgets and document the basis for agreed adjustments.Identify cost gaps, scope omissions, inconsistencies, duplicate costs, unrealistic assumptions, and emerging cost trends.Develop clear recommendations regarding estimate reliability, cost exposure, and areas requiring further evaluation.Construction Change & Commercial EstimatingPrepare cost-impact analyses for potential changes, directed changes, design revisions, field conditions, and contract modifications.Evaluate contractor change proposals and independently assess labor, equipment, material, subcontractor, overhead, markup, schedule-related, and other proposed costs.Support project teams during change-order and contract-amendment negotiations through development of independent cost positions and supporting documentation.Coordinate with design and construction teams and conduct site visits when required to validate actual field conditions, quantities, access constraints, construction methods, and change scope.Support evaluation of claims and commercial impacts by providing independent cost analysis and documentation.Construction Market Intelligence & Cost BenchmarkingResearch and monitor Seattle and Pacific Northwest construction market conditions, including labor availability, prevailing wage rates, material pricing, equipment costs, subcontractor capacity, escalation, supply-chain conditions, and contractor market activity.Develop and maintain historical and current construction cost databases using bid results, completed projects, current market pricing, industry-standard databases, and other reliable sources.Benchmark project costs against comparable transportation and transit projects.Develop and maintain unit-cost information for major civil, structural, rail, systems, utilities, facilities, and other transportation work.Analyze bid results and market trends to continually improve estimating accuracy.Advise project leadership regarding potential impacts of market conditions, escalation, procurement timing, and construction packaging on project cost.Risk, Contingency & EscalationParticipate in project risk assessments and identify cost risks and opportunities associated with design development, construction, procurement, market conditions, interfaces, and project delivery.Develop and support cost contingency and escalation analyses appropriate to project maturity and risk.Perform or support Quantitative Cost Risk Analysis (QCRA) and probabilistic cost modeling using Monte Carlo simulation.Use @RISK, Crystal Ball, or comparable risk-analysis tools where appropriate.Support development of project contingency recommendations and confidence-level cost forecasts.Evaluate the potential cost consequences of identified project and program risks.Coordinate closely with risk managers, schedulers, project managers, and project controls staff to align cost risk with schedule risk and overall program forecasts.Cost & Schedule IntegrationWork closely with project schedulers to align estimates with construction sequencing, durations, phasing, access requirements, procurement strategies, testing requirements, and project milestones.Develop time-phased cost forecasts and cash-flow projections based on project schedules.Evaluate the cost implications of alternative construction sequencing, phasing, packaging, and delivery strategies.Integrate estimating information with scope, schedule, risk, change, and project controls data to support comprehensive project forecasting.Support cost and schedule scenario analyses for potential design, construction, procurement, and delivery alternatives.State of Good Repair & Operating Transit EnvironmentsDevelop estimates for State of Good Repair, rehabilitation, replacement, and modernization projects within active transit operating environments.Evaluate cost impacts associated with limited work windows, rail access, outages, shutdowns, temporary systems, maintenance-of-service requirements, mobilization, staging, and operational constraints.Incorporate appropriate productivity assumptions and cost allowances for work performed within active rail and transit environments.Coordinate with operations, maintenance, systems, construction, and scheduling personnel to understand access and operational constraints affecting construction costs.Reporting &
