Responsibilities

Build the Foundation for Complex Data Center Projects

Join Shawmut's Mission Critical team and help shape complex data center projects before construction begins. As an Assistant Preconstruction Manager, you will manage assigned trade packages across multiple pursuits, partner with Preconstruction and Operations leaders, and contribute to the budgets, scopes, bid strategies, and client deliverables that set each project up for success.

This hands-on opportunity is designed for a construction professional with prior Mission Critical/data center experience who is ready to take greater ownership of trade packages and preconstruction deliverables while continuing to deepen their technical and estimating expertise.

Manage Trade Packages and Bidding

• Manage assigned trade packages across multiple concurrent projects, typically overseeing five to seven active scopes at a time.

• Lead subcontractor outreach, invitation management, bid follow-up, and competitive participation tracking.

• Develop clear scopes of work and bid instructions so subcontractors price work consistently.

• Review subcontractor proposals and level bids to identify clarifications, exclusions, gaps, and potential risk.

• Prepare bid comparisons and recommendations for review by project leadership.

• Build strong, productive relationships with subcontractor partners.

Support Estimates and Procurement

• Support conceptual budgets, milestone estimates, and guaranteed maximum price proposals.

• Perform quantity takeoffs and validate estimates to support budget development and subcontractor bid verification.

• Identify value engineering opportunities, cost-saving alternatives, procurement risks, and key cost drivers within assigned scopes.

• Support procurement schedules, package strategies, and buyout recommendations.

• Complete detailed variance reporting and provide practical value engineering recommendations.

Partner Across the Project Lifecycle

• Contribute technical input and cost data to client presentations, estimate reviews, and proposals.

• Partner with Preconstruction and Operations to keep project information accurate, organized, and ready for decisions.

• Organize estimate backup, scope summaries, and trade package documentation for project turnover.

• Uphold Shawmut's quality standards in your work with internal teams and subcontractor partners.

Build Technical Expertise

• Develop a detailed understanding of assigned systems, including scope requirements, market conditions, procurement strategies, and cost drivers.

• Rotate through major building systems to build broad technical and estimating knowledge.

• Continue developing toward increased scope responsibility and full project ownership.

Qualifications

• Prior hands-on experience supporting Mission Critical/data center construction projects is required, with direct involvement in preconstruction, estimating, procurement, or trade package management.

• At least three years of experience in preconstruction, estimating, project engineering, or a related construction field, including experience on data center projects.

• A bachelor’s degree or equivalent experience.

• Demonstrated experience managing subcontractor bidding, developing scopes of work, performing quantity takeoffs, and reviewing and leveling subcontractor proposals.

• Experience supporting conceptual budgets, milestone estimates, or guaranteed maximum price proposals for Mission Critical/data center projects.

• Working knowledge of data center building systems relevant to assigned trade packages, including scope requirements, cost drivers, and procurement considerations.
