Critical Clauses in Construction Contracts
A well-drafted construction contract isn’t just legal protection—it’s a project roadmap. Below are essential clauses you’ll find in most standard contracts:
1. Scope of Work
Clearly defines what work is to be performed. A vague scope is a breeding ground for disputes.
(a) Includes technical specs, drawings, and project milestones
(b) Should align with the BOQ and project timeline
2. Bill of Quantities (BOQ)
A detailed list of materials, labor, and costs. It’s crucial for pricing, progress payments, and evaluating variations.
3. Time for Completion
Specifies the contract duration and project milestones. Should include:
(a) Start and completion dates
(b) Milestones for specific phases
(c) Allowable delays and conditions for time extensions
4. Liquidated Damages (LDs)
Pre-determined penalties for late completion. This protects the client from financial losses due to delays.
(a) Must be a genuine pre-estimate of loss
(b) Enforceable only if clearly stated in the contract
5. Retention
A percentage of each payment held back to ensure project completion and quality.
(a) Typically 5-10% of contract value
(b) Released after defects liability period or final inspection
6. Escalation Clause
Accounts for inflation or cost changes in materials and labor during long-term projects.
(a) Helps avoid financial losses due to unforeseen price increases
(b) Can be fixed formula-based or linked to price indices
Performance Guarantees, Bonds, and Insurance
These are risk-mitigation tools to ensure project delivery and cover unforeseen liabilities.
1. Performance Bonds
Guarantees that the contractor will complete the work according to contract terms. If they fail, the client can claim compensation.
(a) Typically 5–10% of contract value
(b) Issued by banks or insurance companies
2. Advance Payment Bonds
Protects the client’s advance payment in case the contractor defaults early.
3. Insurance Requirements
Every construction contract should define insurance obligations, including:
(a) Contractor’s All Risk (CAR) Insurance
(b) Third-Party Liability
(c) Worker’s Compensation and Employer’s Liability Insurance
(d) Professional Indemnity Insurance (for consultants)
(e) Subcontracting Provisions
Most large-scale projects involve subcontractors, but improper subcontracting can lead to major legal and operational problems.
Key points to include:
(a) Whether subcontracting is allowed (fully, partially, or with permission)
(b) Approval process for selecting subcontractors
(c) Main contractor’s responsibility for subcontractor performance
(d) Flow-down of contract obligations (ensuring subs comply with main contract terms)
Tip: The main contractor is usually fully liable for delays or defects caused by subcontractors—make sure the risk is managed contractually.
How to Review Sample Construction Contracts
Reviewing contracts—whether standard or custom-drafted—is an essential skill. Here’s what to focus on:
1. Read Clause by Clause
Start with key commercial terms, then move to technical and legal clauses. Take note of:
(a) Payment schedules
(b) Delay penalties
(c) Termination conditions
(d) Dispute resolution process
2. Check for Consistency
Ensure consistency across the Scope, BOQ, drawings, and specifications. Inconsistencies can lead to disputes later on.
3. Understand Governing Law
International contracts may be subject to foreign laws. Make sure you understand:
(a) Jurisdiction clauses
(b) Arbitration vs litigation options
(c) Local legal compliance
4. Highlight Red Flags
Watch out for:
(a) Unlimited liabilities
(b) Unclear escalation procedures
(c) One-sided termination clauses
(d) Onerous insurance or guarantee requirements
Conclusion
A construction contract is not just legal paperwork—it’s a vital management tool that governs cost, quality, time, and risk. Knowing how to draft and interpret contract clauses, manage guarantees and insurances, and handle subcontracting arrangements helps protect your project from costly setbacks.
Whether you’re reviewing a FIDIC Red Book or a locally developed contract, clarity, completeness, and compliance should be your guiding principles.
