Documents and scope
Drawings, specifications, addenda, proposal commitments, exclusions, and missing inputs.
Review methodology
More than scope. More than arithmetic.
BidLayer follows the estimate from contract requirement through the operating plan and final selling price.
Review areas
Six disciplines. One evidence standard.
Every qualifying estimate is reviewed area by area, and the readiness record states what was checked and what was not — areas outside a review are named, never silently passed.
Quantities and materials
Units, waste, laps, coverage, package rounding, fasteners, accessories, and duplicates.
Labor and schedule
Activities, production rates, labor-hours, crew size, duration, supervision, and cleanup.
Equipment and logistics
Cranes, lifts, trucking, disposal, delivery, staging, owned equipment, and mobilization.
Quotes and project costs
Supplier and subcontractor scope, permits, engineering, testing, warranties, and escalation.
Cost and margin
Extensions, omitted or duplicated costs, selling price, gross-profit dollars, and margin sensitivity.
Evidence standards
Software finds the issue. People make the decision.
BidLayer is an independent second set of eyes—not an autonomous estimator and not a substitute for licensed or experienced judgment.
✓Every material finding links back to its estimate line and supporting document.
✓Documented facts, calculations, assumptions, and missing information remain distinct.
✓Calculations are visible and can be independently checked.
✓Authorized reviewers decide whether a bid is ready and which risks to accept.
Questions
Built to fit the way serious estimates are reviewed.
Does BidLayer replace our estimating software?
No. BidLayer sits between estimating and approval. Your team continues building estimates in tools such as EDGE, Excel, and Bluebeam, then uses BidLayer for an independent, structured review.
Does BidLayer approve bids automatically?
No. BidLayer organizes evidence, calculations, findings, and correction status. An authorized person remains responsible for the final approval and for accepting any unresolved risk.
What goes into a review?
A complete review can include the estimate, proposal, drawings, specifications, addenda, RFIs, supplier and subcontractor quotes, schedule assumptions, and company standards.
What makes the review repeatable?
BidLayer applies the same review structure, evidence requirements, deterministic calculations, severity definitions, and approval workflow across every qualifying estimate.
Is BidLayer limited to checking arithmetic?
No. Arithmetic is only one layer. BidLayer also reconciles scope, quantities, labor, production, crew duration, supervision, equipment, logistics, sheet metal, project costs, quotes, and margin.
