Mechanical Construction Estimator (HVAC & Plumbing)

Gulfstream Strategic Placements

Job Description

Snapshot / Role Overview

We're seeking a Mechanical Construction Estimator in Fountain Valley, CA to own full-cycle HVAC and plumbing bids on large commercial and healthcare mechanical projects from conceptual budget through bid-day execution.

Impact

Produce accurate HVAC, plumbing, and piping estimates that directly determine which projects the company wins and at what margin.
Strengthen the company's competitive position on HCAI healthcare and large commercial work across Southern California.
Deliver reliable conceptual budgets early in design-assist and design-build pursuits and refine them as drawings develop.
Give project management a clean, well-documented handoff that reduces post-award surprises.

Responsibilities

Complete quantity takeoffs for ductwork, HVAC piping, plumbing, sheet metal, and mechanical equipment using platforms such as Trimble AutoBid, QuickPen, FastPipe, FastDuct, or Bluebeam.
Price labor units and material costs for plan-and-spec, design-assist, and design-build bids.
Develop conceptual budgets and update them as design progresses through construction documents.
Solicit, review, and level vendor and subcontractor quotes for accuracy and scope coverage.
Identify value engineering opportunities across HVAC, plumbing, and piping scopes.
Prepare scope letters, qualifications, and exclusions for each proposal.
Execute bid-day coordination and final number assembly.
Deliver organized estimate packages to project management at award.

Requirements

Must-Haves

Dedicated commercial mechanical estimating experience covering both HVAC and plumbing scopes.
Proven ability to perform takeoffs and price ductwork, hydronic piping, domestic water, and waste and vent systems.
Experience estimating plan-and-spec, design-assist, and design-build projects.
Proficiency with at least one industry takeoff platform.
Ability to read and interpret mechanical drawings and specifications for scope gaps and constructability issues.

Nice-to-Haves

Healthcare or HCAI project estimating experience.
Familiarity with medical gas pricing and requirements.
Background in Trimble AutoBid, QuickPen, FastPipe, FastDuct, or Bluebeam.

Compensation & Logistics

Competitive salary depending on experience, plus benefits.
