What is adjudication in construction?

Adjudication is a quick, binding-for-now process for resolving a construction dispute. Under the Construction Act, a party to a construction contract can refer a dispute to adjudication at any time, and the adjudicator usually decides within 28 days.

How it works

One party serves a notice of adjudication and then refers the dispute to an adjudicator, who is appointed under the contract or by a nominating body. The adjudicator usually decides within 28 days of the referral, which can be extended with agreement.

What a decision means

The decision is binding unless and until the dispute is finally decided by a court or arbitration, or the parties agree otherwise. Courts generally enforce adjudicators' decisions quickly.

Why evidence decides it

The timetable is short, so you need your records ready. Dated site entries, photos, instructions, notices and the valuation history are what an adjudicator works from.
