JOB OVERVIEW

The Electron-Ion Collider (EIC) Project Infrastructure Independent Construction Cost Estimate (A-E Cost Estimation Services) is a specialized Architect-Engineer (A-E) consulting service that develops an independent, detailed construction cost estimate to verify the accuracy, completeness, and reasonableness of projected construction costs for infrastructure supporting the Electron-Ion Collider (EIC) at Brookhaven National Laboratory.
Where It Is Relevant: The project is located at Brookhaven National Laboratory (BNL) in Upton, Long Island, New York, operated by Brookhaven Science Associates, LLC (BSA) for the U.S. Department of Energy (DOE). The services apply specifically to New York State Work Package No. 02, covering construction of support buildings, foundations, electrical distribution systems, process cooling infrastructure, underground utilities, tunnel connections, and related site improvements.
Why It Is Important: The Electron-Ion Collider is a major scientific research facility designed to investigate the internal structure of protons and atomic nuclei. Its specialized infrastructure requires substantial construction investment and precise cost planning. An independent estimate provides an objective assessment of construction pricing, identifies discrepancies and potential cost risks, and helps ensure that proposed contractor pricing is fair, reasonable, and aligned with the approved engineering design before construction contracts are awarded.
The ProSidian Engagement Team would review 100% detailed engineering drawings and specifications, calculate construction material quantities, validate labor and equipment costs, develop an AACE Class 1 construction cost estimate, and reconcile differences with the project Architect-Engineer and BSA. Expected Outcome(s) include, but are not limited to, a documented, defensible, independently validated construction cost estimate that strengthens procurement decisions, improves budget accountability, reduces pricing uncertainty, and supports cost-effective delivery of EIC infrastructure. Delivers independent construction cost estimates, validates pricing, reconciles discrepancies, and ensures cost-effective infrastructure project execution.
The Senior Construction Cost Estimator Core Duties: Technical lead; AACE Class 1 ICE, BOE, pricing methodology, integrated quantity/cost estimates, vendor quote verification, cost reconciliation,
Serve as a Senior Cost Estimator/Cost Engineer with direct PWS-basis functional coverage for Estimate classification; quantified takeoffs; rates/crew productivity; indexes/markups; reconciliation spreadsheets and Measurement; evaluation; technical execution; data synthesis; quality as Lead technical key person; certification/qualifying experience to confirm.
The Senior Construction Cost Estimator shall principally focus on requirements to provide EN | Engineering Solutions — Independent Cost Estimating | Build a defensible, detailed Class 1 construction estimate that validates pricing and supports confident contract awards.

Client Environment: Federal laboratory environment supporting complex accelerator infrastructure, scientific research, procurement, and construction oversight.
