Dimension Kreo bidyou.ai
Primary input BIM / IFC 3D models. Their AI agent matches model elements against textual specs to flag discrepancies. Anything: PDFs, Excel BoQs, DWG/DXF drawings, photos, free-text descriptions. We work whether your team lives in BIM or in PDFs.
Estimating scope Quantity surveying — extraction of measurements from BIM. Pricing and full estimating are downstream tools. End-to-end: parse → match codes → assign labour coefficients → query suppliers and marketplaces → output a costed bid.
Drawing handling Optimised for BIM-native workflows. If your project is 2D PDF + DWG, you preprocess into BIM first. YOLOv11 + PaddleOCR work directly on the formats your subcontractors actually send: PDFs (text or scan), Excel BoQs, DWG/DXF.
Marketplace lookup No. Pricing comes from your own supplier database or manual entry. Yes. Live aggregation across whitelisted retailers and marketplaces per country. Items not in your catalogue get 5 ranked options.
Trained on your data Generic AI models with industry-shared training data. No per-customer fine-tuning that learns from your closed bids. Per-tenant vector store. Every accepted line refines your model. Two contractors using bidyou.ai get different recommendations because they had different histories.
Audience Quantity surveyors and BIM-mature contractors. Civil and structural workflows. Estimators across electrical, HVAC, plumbing, civil — plus homeowners pricing renovations.
Pricing for SMB Annual seat licences typically £100–300+/seat/month. BIM-Lite and project-based options exist but require sales contact. Free forever for 3 active projects. Starter €39/mo, Pro €129/mo, Enterprise on-prem or dedicated.
Setup requirements BIM model required for full value. Without it, the AI takeoff fallback is closer to a 2D measurement tool. No tooling requirements. Sign up, drop a drawing or BoQ, see the AI draft.
Where it shines Your project is BIM-mature, you have IFC/Revit models for everything, and you want AI to compare-and-flag against the spec. Your real-world inputs are messier than BIM — PDF specs, DWG drawings, Excel templates from subs — and you still want AI to do the heavy lifting.
BIM matures one project at a time. AI estimating shouldn't have to wait. We built bidyou.ai to add value on the bid that lands tomorrow — not on the project that gets BIM-modelled in two years.

Estimate the project as it actually arrives.

Free for the first 3 projects. Works on PDFs, Excel and DWGs without preprocessing — and gracefully accepts BIM/IFC where you have it.

No credit card. No commitment.
