Sr. Electrical Estimator

About Us

Quanta Power Solutions brings together the industry-leading capabilities and resources of Quanta's operating companies to deliver complete EPC solutions. Our integrated approach spans power generation, battery energy storage, renewables, transmission, substation, and underground infrastructure — from concept to commissioning, we execute complex power infrastructure projects with the speed, certainty, and operational excellence our customers depend on.

 

At Quanta Power Solutions, we are driven by a culture of safety, integrity, and disciplined execution — and we're building a team that shares that commitment.

About this Role

The Electrical & Instrumentation (E&I) Estimator is a critical member of our Preconstruction group, responsible for developing detailed and accurate cost estimates for the electrical and instrumentation scopes of EPC power generation and energy infrastructure projects. E&I represents one of the most technically complex and highest-value scopes on a power plant, encompassing everything from generator step-up transformers and high-voltage switchgear to plant-wide instrumentation, distributed control systems, and protection and control schemes. 

 

The ideal candidate brings deep knowledge of power generation electrical systems and I&C architecture, can accurately quantify cable, conduit, raceways, equipment, and instrumentation from single-line diagrams, electrical equipment lists, and I&C drawings, and understands how those systems drive cost, schedule, and labor in a large-scale EPC environment. 

What You'll Do

Estimating & Quantity Development 

• Develop detailed cost estimates for electrical equipment and systems including generator step-up transformers (GSU), high-voltage and medium-voltage switchgear, motor control centers (MCCs), variable frequency drives (VFDs), uninterruptible power supplies (UPS), battery systems, and station service equipment 

• Perform quantity takeoffs for medium-voltage and low-voltage cable, conduit, cable tray, bus duct, raceways, grounding systems, and lightning protection from single-line diagrams, electrical drawings, cable schedules, and equipment layouts 

• Develop estimates for instrumentation and controls scopes including field instruments, analyzers, flow meters, pressure and temperature transmitters, control valves, DCS/PLC hardware, field junction boxes, marshalling panels, and associated wiring and installation activities 

• Estimate fire and gas detection systems, plant communication systems, security and access control, and auxiliary electrical systems supporting power plant operations 

• Evaluate craft labor productivity, electrical installation sequences, termination labor, and construction methodologies specific to power plant E&I environments 

• Produce estimates across all phases from ROM and conceptual through Class 2/1 detailed design, scaled appropriately to available engineering deliverables 

Collaboration & Coordination 

• Collaborate closely with engineering, procurement, construction, and project management disciplines to validate estimating assumptions, constructability, and project execution strategies 

• Interface with electrical equipment vendors, I&C suppliers, and electrical operating units to solicit, scope, and evaluate quotations and bids for accuracy, completeness, and competitiveness 

• Participate in estimate review sessions, risk workshops, bid strategy meetings, and client-facing presentations, clearly communicating scope basis, cost drivers, and key assumptions 

• Partner with project controls to support budget development, schedule integration, and cost tracking on awarded projects 

Cost Modeling & Tools 

• Incorporate risk registers, contingency analysis, escalation factors, indirect costs, equipment installation allowances, and project-specific variables into fully loaded EPC cost estimates 

• Utilize InEight, Autodesk Construction Cloud (ACC), Bluebeam, and Excel-based cost models to develop, manage, and present comprehensive estimates 

• Maintain and continuously improve historical cost databases, unit rate benchmarks, equipment pricing libraries, and labor productivity factors specific to power generation E&I construction 

Proposals & Business Development 

• Support proposal development, owner's engineer reviews, and preconstruction planning for both pursuit and awarded projects 

• Contribute to alternative scope approaches and value engineering opportunities that improve estimate competitiveness
