Contract Administration for London Residential Projects

A building contract sets out the obligations of client and contractor — scope, price, programme, payments and how changes are handled. On projects of any significance, a contract administrator runs that contract impartially during construction: assessing progress, certifying payments, managing variations and instructions, and overseeing the process to practical completion and the defects period. The role brings fairness and structure to the build and protects both parties.

We can act as contract administrator on suitable projects, typically advising on an appropriate form of contract at the outset, administering it during construction, visiting site at intervals to assess progress and general conformity with the drawings, valuing interim payments, managing variations, and dealing with completion and defects. We do not supervise the works continuously or guarantee the contractor’s performance, and we confirm our scope, competence and insurance in writing before accepting the appointment.

During the build, the contract administrator keeps the contract moving fairly. That means assessing the work in place and certifying interim payments so the contractor is paid for what is genuinely done; issuing instructions and valuing variations as the project evolves; assessing claims for extensions of time; visiting site at intervals to check general conformity with the drawings; and then certifying practical completion, managing the defects period, and releasing retention. It is a structured, evidenced role — the connective tissue between the drawings, the money and the programme.

A contract administrator acts impartially between client and contractor, certifying only what is properly due under the contract rather than simply what either party would like. That impartiality is precisely what protects an owner: variations are valued against agreed mechanisms instead of being negotiated under pressure, payments reflect real progress, and disputes have a fair process rather than a stand-off. Running a significant build without this structure — on goodwill and informal arrangements — is where the worst residential disputes tend to begin.

The foundation of good administration is the right contract for the project. The widely used JCT forms range from the Home Owner and Minor Works contracts for smaller jobs to the Intermediate form for larger, more complex builds, each with its own machinery for payments, variations and time. We advise on the appropriate form at the outset and set it up properly, because a contract matched to the size and risk of the work is far easier to run fairly than a generic agreement or, worse, no written contract at all.
