Tendering, Risk & Reporting in OpenConstructionERP

Tendering workflow

1. Prepare the tender BOQ — from the estimate (see oce-estimate-boq), export GAEB X83/X84 for the market.
2. Issue to bidders — track who received, who responded, deadlines.
3. Bid comparison — normalize bids to the BOQ structure (same items, same units), compare line-by-line and totals; flag outliers per line.
4. Risk review — attach risks (cost, schedule, contractual) to BOQ sections; score likelihood × impact.
5. Award — convert the winning bid to the contract baseline (BOQ + schedule freeze).

Risk management

• Risk register per project: description, owner, probability, impact, mitigation, status.
• Risks linked to BOQ lines and tasks — a risk accepted changes the estimate and schedule together.
• Reports: top risks, exposure (risk × contingency), trend.

Report generation

Report	Frequency	Content
Weekly progress	weekly	done vs planned, issues, photos, punch stats
Monthly cost	monthly	budget vs actual per section, forecast
Cash-flow forecast	monthly	schedule × cost roll-up
Closeout	at completion	as-built BOQ, punch closeout, docs

API patterns

GET  /api/v1/boqs/{id}/export?format=gaeb    # tender export
POST /api/v1/risks/                          # risk register
GET  /api/v1/reports/...                     # report endpoints (module-specific)

Best practices

1. Freeze the tender BOQ version — compare bids against the SAME structure.
2. Normalize currencies before comparing bids (never blend).
3. Track bidder clarifications (RFIs) in the tender record, not in email.
4. Keep the risk register alive: review weekly, close or escalate.
