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
