Job summary

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 — including 500 kV and 765 kV programs.

This role owns the estimate from document review through bid-day submission, coordinating with the Chief Estimator and operations leadership to ensure competitive margins.

Qualifications

• 8+ years of estimating experience in substation, switchyard, or high-voltage electrical construction with a self-perform contractor or EPC.
• Demonstrated command of substation construction means and methods across civil, structural, and electrical disciplines.
• Proven track record as lead estimator on competitively bid substation projects of $20M or greater.
• Proficiency with estimating platforms and advanced Excel.
• Ability to read and interpret one-lines, three-lines, and design packages.
• Willingness to travel for site visits and bid reviews (≈25%).

Responsibilities

• Lead complete substation estimates — greenfield stations, expansions, retrofits, and emergency restoration across civil/site development, foundations, raceways, grounding, structural steel, equipment, bus, enclosures, and wiring.
• Perform detailed quantity takeoffs from diagrams and designs; develop quantities from preliminary engineering for bid design.
• Build craft labor, equipment, and crew-based production rates; document means-and-methods in the estimate basis.
• Solicit, level, and evaluate subcontractor and vendor pricing; coordinate major equipment scope and FFP boundaries.
• Attend site visits and pre-bid meetings; assess site conditions and reflect them in the estimate.
• Develop and maintain the estimate risk register; support pricing strategy and risk discussions.
• Present the estimate at internal bid reviews and defend the technical build-up; support proposals and clarifications.
• Lead turnover to project team and capture feedback for cost database and libraries.
• Mentor estimators on takeoff, pricing discipline, and documentation standards.
• EHV experience at 345 kV+; field construction background preferred.

About Us

QISG leverages Quanta’s comprehensive resources to deliver collaborative solutions for our partners' energy infrastructure needs. We use in-house talent, expertise and resources to plan, design, engineer, manage, conduct maintenance on and construct projects.

Our turnkey service capabilities provide our customers with efficiency, consistency, attention to detail and safe execution. The QISG team brings together Engineering, Safety, Quality, Material Procurement, QA/QC, Right-of-Way Acquisition, Scheduling, Environmental Planning, Permitting, Title and Land Management expertise that ensure outstanding results for our clients.

About This Role

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.

What You'll Do

• 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, switchgear) 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 experience.
• AACE certification (CEP or CCP) or DBIA credential.
• Experience estimating under alliance, unit-price, and target-price commercial models in addition to lump sum.

What You'll Bring

• 8+ years of estimating experience in substation, switchyard, or high-voltage electrical construction with a self-perform contractor or EPC.
• Demonstrated command of substation construction means and methods across civil, structural, and electrical disciplines.
• Proven track record as lead estimator on competitively bid substation projects of $20M or greater.
• Proficiency with estimating platforms (HCSS HeavyBid, Accubid, B2W, or equivalent) and advanced Excel.
• Ability to read and interpret one-lines, three-lines, physical arrangements, and civil/structural design packages.
• Willingness to travel for site visits, pre-bid meetings, and bid reviews (approximately 25%).

What You'll Get

• Competitive Compensation
• 401(k) Retirement Plan
• Holiday Pay
• Paid Time Off (PTO)
• Comprehensive Health Coverage
• Pet Insurance
• Employee Assistance Program (EAP)
• Professional Development
• Tuition Assistance
• Employee Discount Program
