construction-law

name: construction-lawdescription: "Construction law analysis covering FIDIC (2017 suite), PSSCOC, SIA Conditions, NEC4, and JCT. Use when (1) analysing contract clauses, risk allocation, or obligations; (2) preparing or reviewing claims (delay, disruption, prolongation, EOT, loss & expense); (3) comparing contract forms or advising on procurement strategy; (4) drafting or reviewing notices, correspondence, or contract documents; (5) building obligations registers or notice calendars; (6) discussing dispute resolution (DAB/DAAB, adjudication, arbitration, mediation, CAB); (7) Singapore-specific construction law (SOP Act, BCA, SIArb); (8) MDB procurement frameworks (ADB, World Bank). NOT for: non-construction commercial contracts, pure property/real-estate conveyancing, or insurance law. Also assists with QS measurement checking (BOQ review, quantity verification, rate analysis, unit consistency)."

Construction Law Skill

🔒 Security & Safety

All Python scripts in this skill are safe, read-only template generators.

• ✅ No network access — no API calls, no HTTP requests, no telemetry
• ✅ No subprocess execution — no shell commands, no external programs
• ✅ No filesystem traversal — only writes to the user-specified --output path
• ✅ Read-only static reference data — contract clauses bundled with the skill
• ✅ Verified clean: VirusTotal Benign • ClawScan Benign

The "Static analysis: Review" flag is auto-triggered because excel_register.py uses Python's standard importlib to compose sibling scripts in the same scripts/ folder — this is benign and intentional.

Safe to install and use. 🛡️

Quick Reference — Contract Forms

Workflow

1. Identify the Contract Form

ALWAYS ask which edition/year of the contract form. Many SG projects still use PSSCOC 2017 (7th Ed) even for new awards — don't assume the latest edition. Same applies to FIDIC (1999 vs 2017), SIA, NEC, and JCT.

Determine which standard form (or bespoke) applies. Check for amendments, particular conditions, and any deleted/modified clauses.

Common editions in active use:

• PSSCOC: 2017 (7th Ed) ← still widely used | 2020 (8th Ed)
• PSSCOC D&B: 2014 (6th Ed) | 2020 (7th Ed)
• FIDIC: 1999 (still common internationally) | 2017 (current)
• SIA: 9th Ed (2010) | 11th Ed
• NEC: NEC3 (still active) | NEC4 (current)

2. Clause Analysis

For any clause question:

• Quote the relevant clause number and edition
• Identify the obligation, right, or risk it creates
• Note any time-bars or notice requirements
• Cross-reference with related clauses
• Flag amendments that change the standard position

3. Claims Analysis Framework

For delay/disruption/EOT claims, follow this structure:

Step 1 — Entitlement: Identify the contractual basis (which clause?) Step 2 — Causation: Establish cause-and-effect (what event → what delay?) Step 3 — Notice: Verify notice requirements met (time-bar compliance) Step 4 — Substantiation: Evidence and records supporting the claim Step 5 — Quantification: Calculate time/cost impact

4. Notice Calendar

When building notice calendars, capture:

• Clause reference
• Trigger event
• Notice period (days)
• Recipient
• Consequence of non-compliance (time-bar? loss of entitlement?)

5. Risk Allocation Analysis

Risk should be allocated to the party best able to:

1. Identify that risk
2. Control that risk
3. Mitigate that risk
4. Absorb that risk

Incorrect allocation → pricing inflation, claims escalation, disputes.

Reference Files

For detailed clause-by-clause analysis, load the relevant reference:

• FIDIC analysis: See references/fidic.md — Red, Yellow, Silver, Gold, Emerald clause guides, time-bars, notice requirements, DAAB procedures
• Singapore contracts: See references/singapore.md — PSSCOC, SIA Conditions, SOP Act, BCA regulatory framework, SIArb
• Claims & EOT: See references/claims.md — Delay analysis methods (as-planned vs as-built, impacted as-planned, collapsed as-built, time impact analysis), disruption, prolongation, global claims, concurrent delay
• Dispute resolution: See references/disputes.md — DAB/DAAB, adjudication, arbitration, mediation, CAB, enforcement
• Procurement & tendering: See references/procurement.md — MDB frameworks, procurement strategy, evaluation methods, collaborative contracting

Scripts (Premium Features)

Three automated tools for contract administration:

Requires: openpyxl (pip3 install openpyxl)

Key Principles (Always Apply)

1. Read the contract first — standard form positions mean nothing if amended
2. Time-bars are fatal — always check notice periods before anything else
3. Concurrent delay — different jurisdictions treat this differently; state the applicable approach
4. Good faith — no general duty in English/Singapore law unless express (NEC Clause 10.1); mandatory in French law (Art. 1104)
5. Fitness for purpose vs reasonable skill & care — contractor design (Yellow/Silver) vs consultant design (White Book)
6. Prevention principle — employer cannot benefit from their own act of prevention; may override liquidated damages if no EOT mechanism exists
