Employment Type: Full-Time
About the Position
We are seeking an experienced Mechanical Estimator with a strong background in HVAC and mechanical piping to join our team in Phoenix, Arizona.
The ideal candidate will have proven experience estimating commercial, industrial, or large-scale mechanical construction projects and be comfortable developing accurate, competitive estimates for projects valued at up to $50 million.
This is an excellent opportunity for an estimator who understands mechanical construction from both a technical and commercial perspective and wants to play a key role in winning major projects.
Key Responsibilities
- Prepare detailed estimates for HVAC, mechanical piping, and related mechanical systems.
- Review drawings, specifications, bid documents, and project requirements.
- Perform quantity takeoffs for equipment, ductwork, piping, insulation, fittings, valves, and other mechanical materials.
- Develop accurate labor, material, equipment, subcontractor, and overall project cost estimates.
- Prepare estimates for projects ranging from smaller commercial work to projects valued at $50 million or more.
- Solicit and evaluate pricing from vendors, subcontractors, and suppliers.
- Analyze subcontractor and supplier proposals for scope, exclusions, and pricing accuracy.
- Identify potential risks, scope gaps, and cost-saving opportunities.
- Develop detailed bid proposals and supporting documentation.
- Work closely with project managers, engineers, vendors, and operations teams during the estimating and preconstruction process.
- Participate in bid reviews and turnover meetings.
- Assist with value engineering and constructability reviews.
- Maintain organized estimating documentation and historical cost data.
- Help develop competitive bid strategies and ensure estimates are submitted accurately and on schedule.
Qualifications
- 5+ years of experience in mechanical estimating, preferably within commercial or industrial construction.
- Strong knowledge of HVAC systems and mechanical piping.
- Experience estimating large-scale mechanical construction projects.
- Proven ability to perform detailed material and labor takeoffs.
- Strong understanding of mechanical construction methods, materials, and installation costs.
- Ability to read and interpret mechanical drawings, specifications, and construction documents.
- Experience with estimating software and/or digital takeoff platforms.
- Strong analytical, mathematical, and problem-solving skills.
- Excellent attention to detail and organizational skills.
- Ability to manage multiple bids and deadlines simultaneously.
Preferred Qualifications
- Experience estimating projects valued at $10M–$50M+.
- Experience with large commercial, industrial, healthcare, semiconductor, data center, or institutional projects.
- Experience with both HVAC and process/mechanical piping.
- Familiarity with BIM/Revit models and using digital drawings for takeoffs.
- Experience with major mechanical subcontractors, general contractors, or construction firms.
- Strong vendor and subcontractor relationships within the Phoenix market.
- Bachelor's degree in Construction Management, Engineering, or a related field is preferred but not required.
What We Offer
- $80,000–$110,000 annual salary, based on experience and qualifications.
- Opportunity to work on high-value mechanical construction projects up to $50 million.
- Career growth within a growing mechanical construction organization.
- Collaborative environment with experienced project and operations teams.
- Opportunity to take ownership of major estimates from initial bid documents through project turnover.
Ideal Candidate
The ideal candidate is a detail-oriented mechanical estimator who understands how HVAC and piping systems are actually built—not just how they appear on drawings. You should be comfortable working with complex plans, developing accurate takeoffs, challenging pricing when necessary, and producing competitive estimates for major construction projects.
If you have the experience to estimate large-scale HVAC and piping projects up to $50 million, we want to hear from you
