Senior Project Estimator – Data Center Preconstruction

In this role you will support green‑field data center projects through full‑project budget validation, independent cost estimating, GC/CM reconciliation, GMP and lump‑sum proposal review, schedule of values review, and value engineering support.

• Review and validate full project budgets and costs across civil, sitework, structural, architectural, mechanical, electrical, fire protection, telecom, low voltage, structured cabling, fiber, general conditions, indirect costs, escalation, contingency, allowances, fees, markups, and soft‑cost interfaces such as design fees, permits, utilities, owner vendors, commissioning, testing, and project contingency.
• Prepare independent estimates at schematic, design development, and 100% construction documentation stages.
• Reconcile independent estimates against GC/CM estimates and identify scope, quantity, pricing, escalation, contingency, assumption, and risk variances.
• Review GMP and lump‑sum proposals, including assumptions, qualifications, exclusions, allowances, unit prices, alternates, general conditions, fees, insurance, bonds, and markups.
• Examine Schedule of Values submissions for reasonableness, completeness, alignment with scope, and front‑loading risk.
• Evaluate bid packages, subcontractor pricing, vendor quotations, and GC/CM estimate submissions for competitiveness and alignment with project scope.
• Identify scope gaps, overlaps, estimate assumptions, pricing risks, long‑lead cost drivers, escalation exposure, contingency needs, and potential budget impacts.
• Support value engineering by developing, reviewing, and tracking accepted and rejected items against budget, scope, and project objectives.
• Prepare clear Basis of Estimate documentation, including scope basis, pricing sources, assumptions, exclusions, escalation, contingency, allowances, and risk notes.
• Create estimate summaries, variance reports, reconciliation logs, cost‑driver analyses, and executive‑level presentations for internal teams and client stakeholders.
• Collaborate cross‑functionally with project management, preconstruction, design, procurement, commercial, scheduling, engineering, GC/CM, and client teams to validate estimate inputs and resolve discrepancies.
• Track historical cost data, benchmarks, market trends, and data center cost drivers to improve estimating accuracy and support informed recommendations.
• Support procurement and award recommendations by reviewing proposal completeness, cost reasonableness, scope coverage, commercial terms, and pricing risks.
• Maintain organized estimate records, assumptions, supporting data, benchmarks, reconciliation files, and methodology documentation for auditability and future reference.

• 12+ years of construction estimating, preconstruction, cost estimating, quantity surveying, or cost advisory experience.
• Bachelor’s degree in Construction Management, Engineering, Quantity Surveying, Architecture, or a related technical field.
• Full‑project preconstruction estimating and cost validation experience across civil, structural, architectural, MEP, fire protection, telecom, general conditions, indirect costs, escalation, contingency, and allowances.
• Demonstrated full‑project estimating across multiple disciplines, not limited to one trade.
• Strong understanding of all major construction disciplines, with particular strength in MEP‑heavy environments and data center MEP intensity.
• Experience with large commercial, industrial, mission‑critical, data center, semiconductor, advanced manufacturing, infrastructure, EPC, or similarly complex capital projects.
• Experience preparing independent estimates and reconciling against GC/CM submissions, GMP proposals, lump‑sum proposals, bid packages, subcontractor pricing, and vendor…
