What is Construction Contract Administration?
Construction contract administration is the management of construction contracts from award to completion. It ensures all parties fulfill their obligations and the project is delivered according to contractual terms.
In Kenya, contract administration must comply with Kenyan contract law, NCA regulations, and international standards like FIDIC for major projects.
📊 Key Fact: Poor contract administration causes 30-50% of construction disputes. Effective contract administration prevents disputes, ensures timely payments, and reduces project delays by 20-40%. Contract administration typically costs 3-8% of construction cost but saves 10-20 times that amount in prevented disputes.
Before contract administration, ensure you have a solid construction schedule and understand bill of quantities preparation.
FIDIC Contract Forms
FIDIC (Fédération Internationale des Ingénieurs-Conseils) publishes internationally recognized standard contract forms widely used in construction.
Main FIDIC Contract Forms
- Red Book: Construction works designed by employer (traditional procurement)
- Yellow Book: Plant and design-build (contractor designs)
- Silver Book: EPC/turnkey projects (contractor takes full risk)
- Gold Book: Design, build and operate (DBO)
- Green Book: Short form of contract (simple projects)
- White Book: Client/consultant model services agreement
FIDIC in Kenya
- Used for major infrastructure projects
- International recognition and acceptance
- Balanced risk allocation between parties
- Clear procedures for claims and disputes
- Widely accepted by financiers and donors
Key FIDIC Principles

| FIDIC Book | Best For | Design Responsibility | Risk Allocation |
|---|---|---|---|
| Red Book | Traditional construction | Employer | Balanced |
| Yellow Book | Design-build | Contractor | Balanced |
| Silver Book | EPC/Turnkey | Contractor | Contractor |
| Green Book | Simple projects | Varies | Simple |
Payment Certificates in Construction
Payment certificates are the mechanism for paying contractors for work completed. They ensure transparency and accountability in construction payments.
Types of Payment Certificates
- Interim Payment Certificates: Monthly payments for work completed
- Final Payment Certificate: Payment at project completion
Payment Certificate Process
- Contractor submits payment application with supporting documents
- Engineer reviews and verifies quantities and quality
- Engineer issues payment certificate
- Employer makes payment within contract time limits
Payment Certificate Contents
- Work completed to date (measured quantities)
- Materials on site (if allowed by contract)
- Variations approved
- Claims approved
- Retention deductions (typically 5-10%)
- Advance payment recovery
- Previous payments deducted
For cost estimation before contract award, see our guide on earthworks cost estimation.
Variations in Construction Contracts
Variations are changes to the original scope of work. They are common in construction and must be properly managed to avoid disputes.
Types of Variations
- Addition to Scope: Extra work required
- Omission from Scope: Work removed from contract
- Change in Quality: Different materials or standards
- Change in Timing: Acceleration or delay
- Change in Location: Relocation of work
Variation Procedure
- Client/engineer issues variation order
- Contractor prices the variation (time and cost)
- Engineer reviews and approves or negotiates
- Work proceeds as per approved variation
- Payment through payment certificates
Variation Management Best Practices
- Document all variations in writing
- Price variations before work commences
- Maintain variation register
- Track cumulative variation value
- Ensure variations are signed by authorized persons
⚠️ Warning: Never proceed with variation work without written approval. Oral instructions are difficult to prove and often lead to disputes. In Kenya, NCA requires that variations be documented and approved by the project architect/engineer of record.
Construction Claims
Claims are requests for additional time or money due to circumstances beyond the contractor's control. Proper claims management is essential for project success.
Common Types of Claims
- Extension of Time (EOT): Delays not caused by contractor
- Additional Payment: Extra costs due to variations, delays, or unforeseen conditions
- Variation Claims: For additional or changed work
- Delay Claims: For employer-caused delays
- Disruption Claims: For loss of productivity
- Acceleration Claims: For being required to accelerate
- Unforeseen Conditions Claims: For unexpected site conditions
Claim Process
- Notice of Claim: Within contract time limits (usually 28 days)
- Detailed Claim Submission: With supporting documents
- Engineer Review: Engineer reviews and determines
- Negotiation: If disputed, parties negotiate
- Adjudication/Arbitration: If unresolved
Claim Documentation Requirements
- Notice of claim within time limits
- Detailed claim with calculations
- Supporting documents (records, photos, correspondence)
- Programme analysis showing delay impact
- Cost records and calculations
For project scheduling to support claims, see our guide on construction scheduling and critical path method.
Retention and Defects Liability Period
Retention and the defects liability period (DLP) provide security for the employer and ensure the contractor rectifies defects.
Retention Money
- Typical Retention: 5-10% of each payment certificate
- Limit: Usually capped at 5% of contract sum
- First Half Release: At practical completion
- Second Half Release: At end of defects liability period
Purpose of Retention
- Ensures completion of work
- Provides security for defect rectification
- Encourages contractor to return and fix defects
- Protects employer from incomplete work
Defects Liability Period (DLP)
- Typical DLP: 6-12 months from practical completion
- Contractor Obligations: Rectify defects at own cost, respond to notifications
- Employer Obligations: Notify defects in writing, allow access
- After DLP: Final retention released, contractor's obligation ends (except latent defects)
Practical Completion
- Work substantially complete
- Can be used for intended purpose
- Minor defects remain (to be fixed during DLP)
- Triggers half retention release
- Starts DLP clock
