Interpreting Ambiguous Contract Clauses: A Practitioner’s Guide
Executive Summary
Ambiguous clauses in construction contracts are among the leading causes of disputes. Poor drafting, inconsistent documents, or inadequate reviews often create uncertainty around obligations such as completion, variations, or force majeure.
This guide highlights the common causes of ambiguity and provides practical steps to interpret and manage unclear terms, including contextual reading, applying industry principles, seeking clarification early, and documenting intent. By addressing ambiguity upfront, Contractors and Employers can avoid costly disputes and protect their project outcomes.
Ambiguity in contract clauses is one of the most common sources of disputes in construction projects. Whether arising from poorly drafted provisions, translation issues, or conflicting terms between contract documents, ambiguity often leaves Contractors and Employers exposed to unnecessary risk.
Why Ambiguity Matters
Unclear terms open the door to disputes over interpretation. A single ambiguous clause, whether on completion dates, variation procedures, or force majeure, can trigger conflicting obligations, project delays, and costly arbitration.
Common Causes of Ambiguity
- Multiple contract documents with inconsistent wording.
- Use of generic templates without project-specific tailoring.
- Poor translation or reliance on “standard” phrases without context.
- Inadequate review before signing.
Practical Guidance
- Contextual Reading – Always interpret clauses in light of the entire contract, not in isolation.
- Apply Industry Standards – Use recognized principles such as contra proferentem (ambiguities interpreted against the drafter).
- Seek Clarification Early – Raise queries during negotiations rather than leaving interpretation to post-dispute stages.
- Document Intent – Record meeting minutes or side agreements clarifying intent behind ambiguous terms.
Key Takeaway
Ambiguity is not just a drafting flaw, it is a risk trigger. Contractors and Employers must invest in careful contract review and, where necessary, independent legal advice before execution.
