Join Our Team as a Preconstruction Estimator II

Ready to take on more independent estimating responsibility and contribute 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. We're seeking a skilled Preconstruction Estimator II to 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.

Why Join Us?

  • Commitment to Excellence — We deliver precise, thorough estimates that minimize risks and maximize project success from preconstruction through execution.
  • Growth & Development — Build on your experience with mentorship, exposure to diverse projects, and opportunities to advance in estimating and preconstruction.
  • Collaborative Environment — Partner with sales, engineers, project managers, and field teams to create value-engineered solutions for clients.
  • Great Perks — Competitive compensation and benefits, professional training, and a supportive culture focused on work-life balance.

What You'll Do As Preconstruction Estimator II

This mid-level role builds on foundational estimating skills, allowing you to handle full estimates for mechanical projects with increasing independence. Reporting to the Preconstruction Services Manager, key responsibilities include:

  • Preparing detailed and conceptual cost estimates for commercial HVAC, plumbing, piping, and mechanical projects (plan-spec, design-build, and cooperative purchasing).
  • Thoroughly reading, interpreting, and analyzing contract documents (plans, specifications, addenda, scopes of work, and general conditions).
  • Performing accurate quantity takeoffs from drawings and specs for materials, labor, equipment, and subcontractor scopes.
  • Organizing estimate data, pricing information, and assumptions; soliciting and clarifying pricing from suppliers, vendors, and subcontractors.
  • Assisting in (and increasingly leading) the preparation of complete bid proposals, RFP/RFQ responses, bid packages, and presentations for submittal.
  • Identifying potential risks, value engineering opportunities, constructability issues, and cost-saving alternatives during the estimating process.
  • Maintaining complete, organized project records, estimate files, and documentation for audits and handoffs to operations.
  • Supporting senior estimators and preconstruction team with special projects, research, bid strategy input, and administrative tasks as needed.
  • Conduct job walks, as needed, to assess existing site conditions and develop the project approach.

What We're Looking For

  • 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 required.
  • 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.

If you're a motivated estimator with a passion for mechanical trades, enjoy turning plans into competitive numbers, and want to grow with a company that values precision and teamwork, apply today! Join Modigent and help secure the next wave of successful commercial projects.
