The product
AlphaBid replaces the click-counting, the manual Excel entry, and the bid-day PDF cleanup with one browser-based loop — purpose-built for Canadian plumbing, mechanical, and HVAC contractors.
Pipe runs, fixtures, joints, slab coring, equipment locations — plus demolition scope: removal piping traced from the hatched overlay and cut-and-cap notes priced as labor. Built for real multi-discipline sets: the same fixture drawn on architectural and mechanical sheets counts once, schedules reconcile against plans, and elevations never double-count. The model reads the set the way an experienced estimator would, including general notes, drawing notes, and CSI specifications.
A 19-worksheet Excel workbook: scope checklist, room hierarchy with tags, pipe takeoff, fittings, hangers, fixtures, materials, buyouts, labor, demolition register, spec library, RFI log, and a system-QC report — every sheet sorted for review, every quantity tagged with how it was measured.
Before you price, AlphaBid checks that the extracted plumbing systems make sense: every fixture traced toward its source, missing valves and unsized runs flagged with the sheet, page, and room to check, and the suggested correction — ending in a clear release verdict. It even catches drawing-set coordination errors, like a mechanical sheet whose room tags are a revision behind the architectural set, and writes the RFI for you.
Lifts, core rigs, jetters, disposal bins, test pumps — a contractor-tunable rule catalog decides what the job needs from the evidence, prices rentals into the buyouts sheet, and flags anything that needs a specialist quote. Nothing is guessed: incomplete evidence goes to review, not into the bid.
Your logo, contact details, HST line, line items, totals. A professional PDF the client sees — submit-ready, no formatting work on bid day.
Ask the AI anything about the drawing set. "How many hand sinks?" "What backflow is spec'd?" "Where does the 4" main change to 2"?" Answers grounded in the actual plans.
Drop in an addendum. See exactly what changed against the prior set — added fixtures, moved runs, schedule deltas — and update your quantities in one step.
Every detection, edit, and export is logged. When the GC asks how you got the number, you can show them. Useful at bid review. Critical at change-order time.
Workflow
Drop the mechanical PDF in. Multi-page sets, addenda, and scanned drawings all handled.
Pipe sizes, lengths, fixture counts, joints, slab coring, demolition scope, notes and specs — pulled the way an estimator would pull them, then QC-checked system by system.
Editable 19-sheet Excel takeoff with a QC verdict and a top-actions list telling you exactly which sheet, page, and room to double-check. Apply your unit costs, your assemblies, your judgement.
Branded PDF with your logo, address, HST line, line items, totals. Looks like you've had it formatted for years.
Attach the PDF, hit send. The takeoff that used to take a week is done in an afternoon.
"We've been building AlphaBid with the Coultice estimators on real GTA mechanical jobs since day one. They tell us what's missing in the legacy tools, what would save them a day a week, and what we'd be crazy to ship without."
