Bid Coordinator – MUST SPEAK AND WRITE FLUENT ENGLISH

MAG Construction, Inc. (MCI) is seeking a highly organized and detail-oriented Bid Coordinator to support our growing Preconstruction and Estimating Department.

MCI is a South Florida specialty contractor providing Plumbing, Mechanical/HVAC, and Electrical (MEP) construction services across commercial, multifamily, institutional, and public-sector projects. As our project pipeline continues to grow, the Bid Coordinator will play a critical role in keeping opportunities organized, ensuring bid requirements are met, coordinating subcontractor and vendor participation, and supporting our estimating team from invitation through proposal submission.

This is an excellent opportunity for someone who understands the construction bidding environment and wants to grow within a fast-paced MEP contractor.

Key Responsibilities

- Receive, review, and organize incoming Invitations to Bid (ITBs) from general contractors and clients.
- Maintain MCI's bid calendar and opportunity pipeline, including bid dates, addenda, RFIs, deadlines, and submission requirements.
- Download, organize, and distribute plans, specifications, addenda, bid forms, and scope documents to the estimating team.
- Review bid invitations and identify the MEP disciplines included in each opportunity.
- Coordinate with estimators to confirm bid/no-bid decisions and internal estimating assignments.
- Prepare and distribute RFQs to subcontractors, vendors, and suppliers.
- Follow up with vendors and subcontractors to ensure adequate pricing coverage before bid day.
- Maintain organized bidder lists and track vendor/subcontractor responses.
- Assist estimators with obtaining major equipment and material quotations.




- Track addenda and ensure all estimating documents remain current.
- Review GC bid requirements, scope sheets, proposal forms, alternates, allowances, and required qualifications.
- Assist with assembling professional bid proposals, scope letters, exclusions, clarifications, and supporting documentation.
- Ensure proposals are complete and submitted accurately and on time.
- Maintain historical bid information, proposal files, and estimating documentation.
- Track bid results and assist with follow-up after proposal submission.
- Coordinate handoff documentation when a project transitions from Estimating/Preconstruction to Operations.

What We're Looking For

- 1–3+ years of experience in construction estimating, preconstruction, bid coordination, project coordination, or a similar role preferred.
- Experience working for a general contractor, MEP contractor, plumbing contractor, mechanical contractor, or electrical contractor is highly preferred.
- Ability to read and navigate construction drawings, specifications, and bid documents.
- Strong understanding of construction terminology and the bidding process.
- Excellent organizational and document-control skills.
- Strong written and verbal communication skills.
- Comfortable communicating with general contractors, suppliers, subcontractors, and internal estimators.
- Ability to manage multiple bids and deadlines simultaneously.
- Strong proficiency with Microsoft Excel, Outlook,



PDF/plan review software, and cloud-based construction platforms.
- Experience with estimating or construction management software is a plus.
- Detail-oriented with a strong sense of urgency and accountability.

Adecuado Candidate

The ideal Bid Coordinator is someone who keeps the estimating department ahead of deadlines rather than reacting to them.

You should be comfortable managing several active opportunities at once, following up persistently with vendors and subcontractors, identifying missing information, and making sure the estimating team has everything necessary to submit a complete and competitive proposal.

This position requires someone who is organized, proactive, responsive, and willing to take ownership of the bidding process.
