Contract administration in construction: the role, the paperwork and where AI helps

Contract administration is mostly paperwork against the clock: instructions, valuations, certificates and notices, each with a date that matters. The decisions need judgement. The drafting, logging and chasing around them are where AI can give you time back.

What is contract administration in construction?

Running a building contract once it's signed: issuing instructions, valuing work, certifying payment and completion, and dealing with delays and changes.

What does a contract administrator do under JCT?

JCT's guidance describes the Architect/Contract Administrator as the professional the employer appoints to advise on and administer the contract. They're paid by the employer, but should act fairly and independently between employer and contractor when they certify, value or extend time.

• Issue instructions to the contractor. The employer can't instruct directly.
• Value variations and work against provisional sums.
• Issue interim certificates for payment, and the final certificate.
• Give a reasonable extension of time when delay is beyond the contractor's control.
• Certify practical completion.
• Certify when defects that appear in the rectification period have been made good.

If the person appointed isn't an architect, the contract calls them the Contract Administrator. The duties are the same.

Who administers an NEC4 contract?

NEC4's Engineering and Construction Contract names two roles, both appointed by the client. The Supervisor checks the work against the Scope, looks after tests and inspections, and notifies defects. The Project Manager handles most of the rest, including instructions, the programme, compensation events, and certifying payment and completion.

NEC4 runs on early warnings, an accepted programme and compensation events. In most cases the contractor must notify a compensation event within eight weeks of becoming aware of it, or lose the right to more time or money. The Project Manager has one week to reply to a notification unless a longer period is agreed, and a late reply can mean a notification, a programme or a quotation is treated as accepted.

What paperwork does contract administration involve?

Instructions, certificates and notices, and JCT publishes a model form for each. Under the Construction Act, a construction contract must provide for a payment notice no later than five days after each payment's due date.

Behind every form sit the records that justify it: site diaries, minutes, letters and, on an NEC4 job, the early warning register. Keeping them current takes time every week, and you'll rely on them in a dispute.

Where can AI help with contract administration?

With the paperwork around each decision: drafting instructions, letters and notices from your notes, keeping registers up to date, turning site diaries and correspondence into records, and flagging dates coming due.

Response times matter most under NEC4. A weekly list of what's coming due, checked by a person against the contract, is a good first job to hand to AI.

What should stay with people?

Anything that takes a position under the contract: whether an event entitles the contractor to more time or money, what a variation is worth, whether the work is complete, and the wording of anything you sign or send. AI can gather the facts and draft; the contract administrator decides and signs.
