Tender & Proposal Readiness

Transforming Drawing Sets into Competitive, Defensible Bids

Winning commercial mechanical, plumbing, and HVAC projects requires far more than rough square-foot allowances or basic material takeoffs. A winning bid demands rigorous document review, complete trade scope isolation, and clear contractual qualifications.

JLG Estimating provides specialized commercial bid estimating services designed to support mechanical contractors during competitive bidding seasons. We dissect contract drawings, review front-end project manuals, integrate your company's specific crew labor productivity, and deliver a comprehensive bid recap ready for executive sign-off.

Built for Demanding Bid Deadlines

Whether bidding as a prime mechanical contractor or submitting a specialized sub-tier bid for plumbing, sheet metal, or piping, our scope checklist and open-item register help the contractor review the agreed package before bid submission.

Risk Protection

Eliminating Common MEP Bidding Blindspots

Commercial bidding failures rarely come from arithmetic errorsβ€”they come from overlooked scope grey areas between trades.

Scope Boundary ItemTypical Risk in Commercial BidsHow JLG Estimating Resolves It
HVAC Equipment Starters & DisconnectsMechanical contractor assumes Electrical provides; Electrical assumes Mechanical provides.We review Electrical Division 26 and Mechanical Division 23 specs to verify who supplies and installs disconnect switches and VFDs, noting exact assignments in your bid letter.
Condensate Drain Lines & TrapsHVAC assumes Plumbing runs the drain; Plumbing assumes HVAC pipes to the nearest hub drain.We trace and quantify condensate lines through terminal floor sinks, clarifying in the scope sheet where mechanical scope ends and plumbing begins.
Roof Curbs, Flashings & PenetrationsRoofer assumes mechanical sets curbs; mechanical assumes roofer flashes penetrations.We itemize factory curbs and call out flashing requirements as an explicit inclusion or GC/Roofing exclusion.
BMS / Temperature Controls WiringControls quotes exclude line-voltage power wiring, causing unexpected field change orders.We separate low-voltage DDC controls from 120V power circuits and clearly tabulate BMS vendor scope versus in-house wiring.
Seismic Restraints & Hanger EngineeringContractors overlook mandatory seismic bracing calculations required by local building codes.We flag seismic requirements identified in structural and MEP general notes, ensuring engineered hanger packages are budgeted.

Bid-Day Partnership

How We Support You Through Bid Day

A successful bid requires active coordination up until the submission bell.

Step 1

Pre-Bid Package Delivery

Preliminary takeoff and draft workbook milestones are agreed at project kickoff based on drawing volume, trade complexity, and your bid deadline.

Step 2

Addenda Reconciliation

When architects issue last-minute revisions, we isolate scope deltas and adjust workbooks immediately so you don't bid outdated drawings.

Step 3

Vendor Quote Integration

When bid-day support is included in the agreed schedule, supplier quotes are entered in the recap with visible inclusions, exclusions and unresolved specification questions for contractor review.

Step 4

Final Recap Review

We join your lead estimator for a final phone review, confirming margin markups, bond rates, and scope letter qualifications before submission.

Define the bid package before closing

  • Identify the bid form, drawing issue, addenda and requested alternates or unit-price schedules.
  • Provide supplier quotations and the wage, burden, tax and markup assumptions your team wants considered.
  • Agree on the scope of quote comparison, clarifications and revisions; retain responsibility for the final tender submission.
