Preconstruction Estimator I

$60k - $80k

Modigent

Preconstruction Estimator I

Position Overview

As a Preconstruction Estimator I, you'll support the early phases of commercial HVAC, plumbing, mechanical systems, and controls projects by assisting senior estimators with quantity takeoffs, pricing, bid preparation, and basic risk/opportunity identification. Working under guidance, you'll help develop accurate conceptual and detailed estimates while learning industry best practices in a collaborative, people-first environment. This entry-to-junior role is ideal for detail-oriented professionals eager to build a career in preconstruction and contribute to winning, profitable projects that deliver sustainable mechanical solutions nationwide at any of our operating companies.

Duties and Responsibilities
  • Assist in the preparation of conceptual, rough-order-of-magnitude (ROM), and detailed cost estimates for HVAC, plumbing, piping, ductwork, and mechanical systems from narratives, schematics, design development, or full construction documents.
  • Review contract documents (plans, specifications, addenda, scopes of work) and perform quantity takeoffs for materials, labor, and equipment.
  • Gather and organize supplier/subcontractor pricing and data under supervision to support accurate budgeting and proposals.
  • Support the assembly and formatting of bid proposals, RFP/RFQ responses, and bid packages for submittal.
  • Maintain accurate, organized project files, estimate records, and documentation.
  • Help identify basic design challenges, constructability issues, and value engineering opportunities.
  • Participate in client and stakeholder meetings as needed to gather scope and provide basic estimating support.
  • Collaborate with internal teams (preconstruction, estimating, operations, sales) and external partners to align deliverables with project objectives.
  • Assist with special projects, research, or administrative tasks related to estimating and preconstruction as assigned.
  • Actively learn commercial construction methods, mechanical systems, estimating techniques, and Modigent standards through on-the-job training and mentorship.
Supervisory Responsibilities

None (entry-to-junior support role focused on learning and assisting senior estimators/preconstruction staff).

Requirements/Qualifications
  • Experience : 1-3+ years of relevant experience in construction estimating, preconstruction, project coordination, or a related field (internships, apprenticeships, or entry-level roles in mechanical/construction count). Recent graduates with engineering or construction management degrees who have strong interest in commercial HVAC/mechanical estimating are encouraged to apply.
  • Education : Bachelor's degree in Construction Management, Mechanical Engineering, Architectural Engineering, or a related field preferred; equivalent experience considered.
  • Physical Demands : Primarily office-based with occasional site visits; ability to walk construction sites, lift light materials (plans, laptop), and travel regionally as needed; standard office mobility for computer work and meetings.
  • Work Environment/Safety : Professional office with hybrid options and occasional active construction sites; exposure to varying weather, noise, dust, heights; must adhere to OSHA regulations, conduct hazard identification, and wear required PPE (hard hat, safety glasses, steel-toed boots) on sites-safety is our top priority and non-negotiable. This is a safety-sensitive position.
Required Skills
  • Basic understanding of commercial construction practices, mechanical systems (HVAC/plumbing/piping preferred), and reading blueprints/specifications.
  • Proficiency in Microsoft Office Suite (Excel essential for data organization and calculations; Word and Outlook for communication).
  • Strong attention to detail, organizational skills, and eagerness to learn quickly.
  • Effective written and verbal communication with a professional demeanor.
  • Collaborative team player with the ability to work toward increasing independence.
  • Commitment to accuracy, quality, and continuous improvement in a fast-paced preconstruction environment.
