Activity Something which needs to be done in a building project, and which is separately identified for the purpose of planning or Retrospective Delay Analysis.
Actual cost This expression is sometimes used as a synonym for prime cost in a cost contract.
Adjudication (i) In the widest sense, any judicial or quasi-judicial process operating otherwise than by default. The word is rarely used in this sense in the construction context.

(ii) A quasi-judicial method of resolving disputes that falls short of litigation or arbitration; usually intended as a process that is both quicker and cheaper than litigation or arbitration. In this sense, defined by the Academy of Experts1 as “Exercise of a power delegated by contract to a third party to resolve disputes on an interim or final basis as they arise without recourse to formal arbitration or litigation”. Until the publication of the Latham Report2 and the Housing Grants, Construction and Regeneration Act 1996, adjudication was, in the construction context, principally used under clause 24 of the JCT nominated subcontract form NSC/4 (formerly clause 13B of the Green Form) for the purpose of determining the right of a main contractor to set off amounts against a subcontractor.

Adjudicator Person who resolves disputes under an adjudication procedure. Under the JCT set-off procedure, the adjudicator is usually a quantity surveyor, but is likely to be drawn from another profession in the wider context. Where there is more than one adjudicator, the adjudicators are usually known as a “panel” or “board”.
ADR Alternative Dispute Resolution, a structured but non-binding method of associating settlement of a dispute, usually by means of mediation and/or mini-trial.

He may or may not have designed the works; his function is to exercise control over the works as they proceed.

Articles of agreement Usually means the articles of agreement which are to be found in the opening pages of the JCT contract.
Artists and tradesmen Expression used in the old JCT contract to mean persons who execute work not forming part of the main contract. The expression was dropped in the 1980 edition. The “artists and tradesmen” clause can apply to statutory undertakers such as electricity or gas boards (see Henry Boot v. Central Lancashire New Town Development Corporation (1980) 15 B.L.R. l).
