What it does

Oce Estimate Boq is an agent skill from datadrivenconstruction/DDC_Skills_for_AI_Agents_in_Construction. 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.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Documents & Office, covering Excel spreadsheets. It works with Microsoft Excel. The repository describes itself as: 221 AI skills for construction: BIM analysis, cost estimation, scheduling, document control, and automation with Claude Code. The licence is MIT.

When your agent uses it

  • Any estimating workflow on the platform
  • Tasks that involve Excel spreadsheets

Example prompts

  • “/oce-estimate-boq”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  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=TR_NATIONAL&q=duvar (SQL search) or the semantic path (/qdrant-search when Qdrant is on). Every…
  4. Link quantities — either manual entry, BIM bulk-link (POST /api/v1/bim/elements/bulk-link style endpoints aggregate area/volume/length per…
  5. Validate — POST /api/v1/boqs/{id}/validate/ runs rule packs (BOQ quality, DIN276, NRM, GAEB) and returns violations; quality score updates…
  6. Export — GAEB X83/X84, XLSX, JSON for tendering.

What it can do on your machine

Read from SKILL.md and the folder at commit ce45bbf. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Oce Estimate Boq loads about 763 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 274 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~763

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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=TR_NATIONAL&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.

Estimation inputs the platform supports

InputPathNotes
Natural languagePOST /api/v1/costs/match (or AI estimate)multi-lingual matching
PhotoAI photo-to-BOQ (GPT-4o + YOLO)returns scoped BOQ with confidence
BIM modelelement → cost matching (/suggest-for-element)uses volume/area from the model
DWG/PDFtakeoff measurementvectors/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 total_cost_per_position; resource sums reconcile to total_resource_cost_per_position.

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. Re-run validation after every bulk edit — the quality score is the fastest signal.
