Pre-Construction Services Manager

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.

About this Role Quanta Infrastructure Solutions Group, LLC (QISG), a Quanta Services, Inc. company (NYSE: PWR) is looking for a Pre-Construction Services Manager is a commercially focused, hands‑on role embedded within QISG's operational organization, responsible for driving the commercial maturation of a project from award through full execution. Working alongside QISG's fully staffed PMO, which handles schedule development, contract deliverable tracking, RFI management, subcontractor coordination, and field execution, this role does not duplicate those functions. Instead, it receives and interprets PMO outputs (design progress, procurement status, schedule updates, change events, and cost data) to build and maintain the progressive EPC estimate and own the open-to-closed book process on behalf of the project. This role serves as the commercial engine that converts project information into updated scope positions, refined estimates, and ultimately a closed book GMP or lump sum that both QISG and the owner can stand behind, acting as the primary interface between what the PMO knows and what the contract needs to reflect. Depending on scope and complexity, this individual may be assigned to a single client relationship, a specific project, or a portfolio of concurrent efforts at varying stages of commercial development. What You’ll Do Duties & Responsibilities Progressive EPC Estimating Assembles and maintains the progressive EPC estimate throughout the pre-construction phase, incorporating updated design information, procurement pricing, and schedule inputs from the PMO as they become available Develops a comprehensive basis of estimate at each stage of the open-to-closed book process, including assumptions, inclusions, exclusions, qualifications, and risk allowances that accurately reflect the current state of design and procurement Reviews vendor and subcontractor proposals, quotes, and procurement data through a commercial lens to validate pricing and ensure alignment with the scoped work and specification requirements Applies current knowledge of labor, material, and equipment market conditions to ensure estimates are competitive, realistic, and reflective of actual market exposure Participates in value engineering and constructability reviews as a commercial stakeholder, evaluating scope or design alternatives for their cost and schedule impact on the estimate Open-to-Closed Book Management Owns the commercial maturation of the project from open book estimate through GMP or lump sum close, maintaining a current and defensible cost position at each stage of the process Receives design progress reports, procurement status updates, schedule information, and change event data from the PMO and translates these inputs into updated scope, cost, and risk positions within the estimate Identifies gaps, unknowns, and unresolved scope items that represent commercial risk, and works with the PMO and Engineering to drive resolution ahead of book close Builds the GMP or lump sum position when design and procurement data is sufficient to support it, establishing the closed book baseline that the execution team will carry forward Owner Alignment & Change Management Serves as the primary commercial interface with the owner during the pre-construction phase, ensuring the client understands the current scope and cost position and how it has evolved from the original award Manages the owner change order process during pre-construction, ensuring that all scope additions, deletions, and owner-directed changes are captured, priced, and formally incorporated into the updated contract position and estimate Facilitates milestone gate reviews and approval meetings with the owner, presenting updated scope, schedule, and cost positions in a clear and structured manner Maintains alignment between owner expectations and project realities as design matures, proactively surfacing commercial issues before they become contractual disputes PMO Information Integration & Teaming Partner Relationships Establishes a regular cadence with the PMO to receive schedule updates, design release status, procurement commitments, and change event logs that inform and update the progressive estimate Works closely with the project scheduler to understand critical path impacts and procurement-driven schedule constraints that affect the cost model Coordinates with the Project Manager to ensure that commercial decisions made during pre-construction are reflected in the project’s baseline and communicated to the execution team Participates in design reviews, procurement meetings, and project status calls as a receiver of information, not as a manager of those processes, ensuring the estimate stays current with project developments Develops and maintains productive working relationships with design teaming partners, ensuring timely access to design deliverables and clear communication of commercial implications as design progresses Transition to Execution Leads the commercial handoff to the execution team, delivering a complete and current package that includes the closed book estimate, basis of estimate, assumptions log, risk register, pending change log, and owner alignment documentation Ensures the Project Manager and project team understand the commercial baseline they are inheriting, including where risks remain open and what assumptions are embedded in the budget Captures lessons learned from the open-to-closed book process and contributes to continuous improvement of QISG’s pre-construction practices and estimating methodologies Adheres to QISG’s internal standards, policies, and operational procedures across all pre-construction and commercial development activities Performs other duties as assigned What You’ll Bring Required Experience and Education Bachelor’s degree in Engineering, Construction Management, or a related field;
