Contract
Administration

What We Deliver

Once construction begins, the contract becomes the primary commercial instrument governing your project. Without rigorous, independent administration, variations accumulate, claims go unchallenged, and the gap between your budget and final cost widens silently.

Zaki QS provides hands-on contract administration that keeps your project commercially tight. We review every claim, assess every variation, and ensure contractual obligations are met, by both parties.

Our Services Include

• Progress claim assessment: independent review and certification of contractor payment claims against contracted rates, measured quantities, and approved scope
• Variation management: assessment of proposed variations, cost impact analysis, and formal change control documentation
• Contract compliance: monitoring contractor obligations including programme, quality, HSE, and reporting requirements
• Payment certification: preparation of payment certificates and recommendations aligned to contract payment terms
• Extension of time assessment: independent review of EOT claims against contract provisions, cause analysis, and entitlement assessment
• Contract closeout: defects liability administration, retention release, final account preparation, and commercial closeout documentation
• Dispute support: commercial analysis and documentation support for contractual disputes and negotiations

Contract Forms We Work With

Our founder has administered contracts under multiple standard forms including AS2124, AS4000, AS4902, NEC, FIDIC, and bespoke principal contracts. Whether your project uses a standard form or a heavily amended agreement, we understand the commercial mechanics.

Homeowner Contract Administration

Building your own home is one of the most significant investments you will make. Yet many individual homeowners enter into construction contracts without the capacity, knowledge, or experience to manage the administration that comes with it. From understanding your contractual rights and obligations to assessing progress claims and managing variations, the process can quickly become overwhelming.

Zaki QS provides dedicated contract administration services for homeowners undertaking residential construction projects. We bridge the gap between you and your builder, ensuring that your interests are protected throughout the build. Our team reviews payment claims, monitors contract compliance, assesses variations and extensions of time, and provides independent advice so you can make informed decisions at every stage.

Whether you are building under a standard HIA or Master Builders contract, or a custom agreement, we bring the same rigour and commercial discipline that we apply to large-scale projects, tailored to your residential build.
