Mid-Level Plumbing Estimator / CAD & BIM Specialist

We're looking for a Mid-Level Plumbing Estimator / CAD & BIM Specialist to join a growing U.S.-based commercial plumbing contractor.

This role is ideal for an experienced plumbing professional who can independently handle plumbing takeoffs and estimating while also working confidently with construction drawings, AutoCAD shop drawings, BIM coordination, RFIs, revisions, and project documentation.

You will work closely with the owner and senior team but will be expected to take ownership of assigned estimates and technical drawing-related tasks with minimal supervision. The ideal candidate has strong commercial plumbing knowledge, understands how plumbing systems are installed in complex projects, and can translate construction documents into accurate quantities, estimates, and coordinated drawings.

What You'll Do

Plumbing Estimating & Takeoffs

• Independently prepare accurate plumbing estimates and quantity takeoffs for commercial construction projects.
• Review architectural, plumbing, mechanical, structural, and civil drawings, specifications, and bid documents.
• Perform detailed takeoffs for plumbing fixtures, piping, equipment, fittings, valves, and other plumbing materials.
• Develop material and labor estimates based on project scope, drawings, specifications, and historical pricing.
• Identify scope gaps, discrepancies, conflicts, and missing information before submitting bids.
• Solicit and coordinate pricing from vendors, suppliers, subcontractors, and manufacturers.
• Prepare complete and competitive bid packages.
• Manage multiple estimates simultaneously while meeting strict bid deadlines.
• Assist with pricing strategies and provide recommendations based on project scope and requirements.

CAD & BIM

• Review and interpret AutoCAD drawings, plumbing plans, details, and shop drawings.
• Prepare, modify, and update plumbing shop drawings using AutoCAD.
• Assist with plumbing layout, drafting, and drawing revisions based on project requirements.
• Participate in BIM coordination and review plumbing models for potential clashes or design conflicts.
• Coordinate plumbing layouts with architectural, mechanical, structural, and other trade drawings.
• Review BIM models and coordination documents to identify conflicts before construction.
• Incorporate design changes, field conditions, and project revisions into drawings and documentation.
• Maintain accurate drawing files, revisions, and technical documentation throughout the estimating and pre-construction process.

RFIs & Project Support

• Prepare and respond to Requests for Information (RFIs) related to plumbing scope, drawings, specifications, and coordination issues.
• Review revised drawings and addenda and determine their impact on project scope and pricing.
• Prepare estimated revisions and change-order pricing when project requirements change.
• Assist with submittals, product documentation, and other project documentation as needed.
• Communicate with project managers, engineers, vendors, and other construction professionals to clarify technical requirements.
• Support the team through the transition from estimating and pre-construction into project execution.

Qualifications

• Minimum 3–5 years of commercial plumbing estimating experience.
• Strong experience with commercial, industrial, multifamily, hospitality, retail, or mixed-use construction projects.
• Ability to independently perform plumbing takeoffs and develop complete estimates.
• Strong understanding of commercial plumbing systems, materials, installation methods, and construction practices.
• Strong ability to read and interpret architectural, plumbing, mechanical, and construction drawings.
• Hands-on AutoCAD experience, preferably with plumbing shop drawings or construction drafting.
• Experience with BIM coordination and construction models.
• Experience preparing, reviewing, or responding to RFIs.
• Experience managing drawing revisions, addenda, and scope changes.
• Familiarity with New York, New Jersey, or Northeast U.S. plumbing codes strongly preferred.
• Civil Engineering degree, construction-related degree, or equivalent plumbing trade qualification preferred.
• Strong understanding of project specifications, plumbing codes, and ADA requirements.
• Ability to work independently with minimal supervision.
• Excellent organizational skills and strong attention to detail.
• Strong written and verbal English communication skills.
• Comfortable working full-time during U.S. Eastern Time business hours.

Required Software & Technical Skills

• AutoCAD – Required
• PlanSwift – Preferred
• Procore
• Microsoft Excel
• PDF markup and construction drawing review tools
• Digital takeoff and estimating software
• BIM software and coordination platforms

Nice to Have

• Experience with Revit MEP
• Advanced BIM coordination experience
• Experience producing plumbing shop drawings
• Experience with Navisworks or similar BIM coordination software
• Experience estimating large-scale multifamily or mixed-use developments
• Experience independently managing RFIs
• Experience with plumbing submittals
• Familiarity with Northeast U.S. plumbing codes
• Experience coordinating plumbing work with mechanical, electrical, structural, and architectural trades

The ideal candidate is not just an estimator or takeoff specialist. We are looking for someone who can bridge the gap between estimating, construction drawings, CAD, and BIM coordination.

You should be comfortable taking a set of construction documents, understanding the plumbing scope, performing the takeoff and estimate, identifying potential issues, reviewing or preparing drawings, coordinating with other trades, and communicating questions through RFIs — all with a high level of independence.

If you have strong commercial plumbing estimating experience and want a role where you can take ownership of both the numbers and the technical side of the project, this could be a strong fit.
