oce-estimate-boq
Create bills of quantities and estimates in OpenConstructionERP: search cost items, build BOQ sections, link BIM elements in bulk, validate the BOQ, and export GAEB/XLSX/JSON. Use for any estimating workflow on the platform.

What this skill does
BOQ & Estimation in OpenConstructionERP Workflow 1. Pick a cost base — load it (see oce-load-cost-bases) so items are searchable. 2. Create the BOQ — POST /api/v1/boqs with project, currency, classification standard (DIN 276 / NRM / MasterFormat / regional). 3. Find items — GET /api/v1/costs/?region=TRNATIONAL&q=duvar (SQL search) or the semantic path (/qdrant-search when Qdrant is on). Every item carries a components[] breakdown (labour/material/machine with norm quantities and unit prices). 4. Link quantities — either manual entry, BIM bulk-link (POST /api/v1/bim/elements/bulk-link style endpoints aggregate area/volume/length per element), or PDF/DWG takeoff measurements. 5. Validate — POST /api/v1/boqs/{id}/validate/ runs rule packs (BOQ quality, DIN276, NRM, GAEB) and returns violations; quality score updates live. 6. Export — GAEB X83/X84, XLSX, JSON for tendering. Cost item anatomy (what the platform stores per item) Estimation inputs the platform supports Input Path Notes --- --- --- Natural language POST /api/v1/costs/match (or AI estimate) multi-lingual matching Photo AI photo-to-BOQ (GPT-4o + YOLO) returns scoped BOQ with confidence BIM model element → cost matching (/suggest-for-element) uses volume/area from the model DWG/PDF takeoff measurement vectors/rooms detected, pushed into BOQ Pricing notes (honest rules) National bases are priced in their home currency; markets are PPP-repriced upstream (no FX inside the platform). Coefficient bases (Vietnam Dinh Muc, Indonesia AHSP) import with rate = 0 — attach a market resource price sheet before estimating. Turkey positions carry the source book's markup (e.g. 25% contractor profit) inside totalcostperposition; resource sums reconcile to totalresourcecostperposition. Best practices 1. Always verify unit matches your takeoff quantity (m²/m³/m/kg). 2. Check the components[] sum against rate before committing a binding estimate. 3. Keep the region currency on the BOQ; never blend currencies in one total. 4. …
