Pre-Construction Manager

About the role

Quanta Infrastructure Solutions Group, LLC (QISG), a Quanta Services, Inc. company (NYSE: PWR), is seeking a Pre-Construction Manager. This role is commercially focused and embedded within QISG's operational organization, responsible for driving the commercial maturation of projects from award through full execution.

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
• Buils 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
• 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
• Coincides 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
• Skills and Competencies
• Strong estimating instincts with the ability to synthesize inputs from multiple sources (design packages, procurement pricing, schedule data, and market conditions) into a coherent and current EPC cost position
• Strong written and verbal communication skills, with the ability to present complex scope, cost, and contract information clearly to both internal teams and owner stakeholders
• Comfortable operating in ambiguous, evolving contract environments where scope and pricing are not yet fixed and commercial judgment is required
• Collaborative and organizationally aware, able to work effectively alongside a PMO without duplicating or competing with established project management functions
• Proficient in Microsoft Office Suite (Word, Excel, Project); Primavera P6 experience preferred for schedule interpretation

Required Experience and Education

• Bachelor’s degree in Engineering, Construction Management, or a related field; equivalent combination of education and demonstrated experience will be considered
• 7+ years of progressive experience in EPC or design-build project delivery, with direct, hands-on involvement in EPC estimating and the open-to-closed book commercial development process
• Demonstrated experience assembling EPC estimates across multiple stages of design maturity, including conceptual, progressive design release, and final GMP or lump sum development
• Direct experience with open book estimate management, GMP development, and lump sum conversion in a post-award, progressive EPC environment
• Working knowledge of current labor, material, and equipment market conditions and the ability to apply that knowledge to produce competitive and realistic cost positions
• Experience on substation, transmission, or utility-scale infrastructure projects strongly preferred; candidates with relevant heavy civil or industrial EPC experience will be considered
• Familiarity with integrated project schedules and the ability to read and interpret schedule outputs as they relate to cost and commercial exposure
• Experience working alongside or within a structured PMO environment, with a clear understanding of how project controls, scheduling, and contract management functions operate
