Job Description

Now Hiring: Estimating Coordinator

📍 El Cajon, CA | 🏢 In-Office | 🛠 Mechanical Contractor | 👷‍♂️ 65 Years Strong

Astro Mechanical is a 65-year-old mechanical contracting company rooted in quality craftsmanship, strong relationships, and a family-style environment where everyone supports one another and wears a few hats when needed. We specialize in commercial, industrial, and government-funded projects, including schools, public buildings, and infrastructure work.

We’re looking for an Estimating Coordinator to join our tight-knit team. This role will primarily support the estimating department—working directly with our Estimator to prepare bids, coordinate subcontractors, and manage proposal documentation. Because we are a small company, this position may also assist with project startup tasks (such as pre-construction RFIs, submittals, scheduling, and O&M manuals) to ensure a smooth handoff into projects.

🔧 What You’ll Do

Estimating & Preconstruction (Primary Focus)

  • Work closely with the Estimator to review drawings and specifications with emphasis on plumbing/pipefitting scope.
  • Perform quantity takeoffs; develop and organize detailed cost estimates.
  • Build bid packages, solicit/evaluate quotes, and track bid schedules.
  • Maintain historical pricing and scope sheets; assist with value engineering.
  • Coordinate with subcontractors and vendors to gather and level proposals.
  • Attend pre-bid meetings and site walks to gather project details.
  • Prepare final bid packages and support proposal submissions.

Project Startup & Limited Coordination (Secondary Support)

  • Prepare and track pre-construction RFIs and submittals during project handoff.
  • Review submittals for compliance with project specifications before forwarding for approval.
  • Maintain a detailed submittal log to ensure timely submissions and avoid construction delays.
  • Support with change order logs, cost tracking, and documentation as needed.
  • Assist with O&M manuals, warranties, final submittals, and closeout deliverables.

🎓 What You Bring

  • Required: Plumbing and/or pipefitting experience (field or estimating).
  • 2+ years in estimating, project coordination, or APM role (mechanical preferred).
  • Experience with government (NAVFAC/federal) and commercial projects a plus.
  • Project HQ (or similar), Bluebeam, and MS Office proficiency.
  • Highly organized, detail-driven, and comfortable with bid deadlines.
  • Strong communication skills and a collaborative, roll-up-your-sleeves attitude.

💼 What We Offer

  • Salary range: $65,000 – $85,000 (DOE)
  • Medical, dental, and vision insurance
  • 401(k) with company match
  • PTO and paid holidays
  • A diverse mix of projects—federal, commercial, and industrial
  • Growth path in estimating
  • A tight-knit, family-style culture where your impact is seen and valued
