Quanta Infrastructure Solutions Group (QISG) is seeking a Senior Estimator with deep substation experience to lead the development of self-perform construction estimates for substation projects across the full voltage range — distribution class through EHV, including work supporting 500 kV and 765 kV transmission programs. This role owns the estimate from document review through bid-day submission: quantities, production rates, means and methods, pricing, and the estimate basis that stands behind the number.

Reporting to the Vice President, Estimating & Pre-Construction, the Senior Estimator works directly with the Chief Estimator, operations leadership, and Quanta operating companies to produce estimates that win work at margins we can deliver.

• Lead complete substation estimates — new greenfield stations, expansions, retrofits, and emergency restoration — covering civil and site development, foundations, below-grade raceway and grounding, structural steel erection, major equipment setting, rigid and strain bus, control enclosures, and protection and control wiring.
• Perform detailed quantity takeoffs from one-line diagrams, physical arrangement drawings, foundation and steel designs, and conduit and cable schedules; develop quantities from preliminary engineering where issued-for-bid design is incomplete.
• Build craft labor, equipment, and crew-based production rates grounded in actual field performance; develop means-and-methods assumptions jointly with operations and document them in the estimate basis.
• Solicit, level, and evaluate subcontractor and vendor pricing; coordinate major equipment scope (transformers, breakers, switch gear) including market lead times and owner-furnished versus contractor-furnished boundaries.
• Attend site visits and pre-bid meetings; assess site conditions, access, laydown, outage constraints, and energized-work requirements, and reflect them in the estimate.
• Develop and maintain the estimate risk register; support pricing strategy and risk posture discussions with the VP of Estimating & Pre-Construction.
• Present the estimate at internal bid reviews and defend the technical build-up; support proposal development and client clarifications through award.
• Lead estimate turnover to the project team at award; capture estimate-to-actual feedback from completed work and return it to the cost database and production rate library.
• Mentor estimators and junior estimators on substation takeoff, pricing discipline, and estimate documentation standards.
• EHV experience at 345 kV and above; exposure to 500/765 kV station construction is a strong differentiator.
• Field construction background (craft, field engineering, or superintendence) prior to estimating.
• Bachelor’s degree in Construction Management, Engineering, or related field, or equivalent field…
