Preconstruction Estimator

Join our team as a Preconstruction Estimator II and take on more independent estimating responsibility while contributing to competitive, winning bids in commercial mechanical construction. At Modigent companies, we provide expert HVAC, plumbing, piping, ductwork, and related mechanical systems for commercial, industrial, and institutional projects across the U.S.

About the role

This mid-level role builds on foundational estimating skills, allowing you to handle full estimates for mechanical projects with increasing independence. You’ll prepare accurate estimates, manage quantity takeoffs, coordinate with suppliers/subcontractors, and support the bid process—working under the guidance of senior preconstruction staff while growing toward leadership roles.

Responsibilities

• Prepare detailed and conceptual cost estimates for commercial HVAC, plumbing, piping, and mechanical projects (plan-spec, design-build, and cooperative purchasing).
• Thoroughly read, interpret, and analyze contract documents (plans, specifications, addenda, scopes of work, and general conditions).
• Perform accurate quantity takeoffs from drawings and specs for materials, labor, equipment, and subcontractor scopes.
• Organize estimate data, pricing information, and assumptions; solicit and clarify pricing from suppliers, vendors, and subcontractors.
• Assist in (and increasingly lead) the preparation of complete bid proposals, RFP/RFQ responses, bid packages, and presentations for submittal.
• Identify potential risks, value engineering opportunities, constructability issues, and cost-saving alternatives during the estimating process.
• Maintain complete, organized project records, estimate files, and documentation for audits and handoffs to operations.
• Support senior estimators and preconstruction team with special projects, research, bid strategy input, and administrative tasks as needed.

Requirements

• 4–7+ years of relevant experience in construction estimating, preconstruction, or mechanical project coordination (commercial mechanical/HVAC/plumbing strongly preferred; related trades considered).
• Solid working knowledge of commercial construction practices, mechanical systems (wet-side/dry-side HVAC, plumbing/piping), and reading/interpreting blueprints/specifications.
• Proficiency with estimating software and digital takeoff tools (Modigent-specific platforms; training provided if needed).
• Advanced Microsoft Excel, Word, and Outlook skills.
• Strong attention to detail, organizational abilities, and analytical/problem-solving mindset.
• Effective written and verbal communication skills with a professional demeanor for internal collaboration and external vendor/subcontractor interactions.
• Ability to work independently on assigned estimates while contributing effectively as part of a team.
• Commitment to accuracy, timeliness, and safety in a fast-paced preconstruction environment.

Benefits

• Competitive compensation and benefits.
• Professional training and development opportunities.
• Supportive culture focused on work-life balance.
