Electrical Estimator

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.

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 switch gear 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.

• Develop detailed cost estimates for electrical equipment and systems including generator step‑up transformers (GSU), high‑voltage and medium‑voltage switch gear, 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
• 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

• 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

• Support proposal development,…
