Interim Adjudication Timelines | Construction Act Deadlines Explained

Why interim adjudication timelines are so strict

The statutory timeframes for adjudication under the Construction Act are intentionally deadline-driven. These rigid limits are not incidental — they reflect a legislative response to longstanding cash-flow and delay problems in the construction industry.

Construction projects depend on timely payment to remain viable. When disputes stall payment, the financial impact can cascade down the construction pyramid, leading to work stoppages, increased costs, and even insolvencies. The adjudication process is structured to prevent these outcomes by ensuring disputes are addressed quickly and decisively while projects remain active.

Unlike litigation or arbitration, which may take months or years to resolve, adjudication operates on an accelerated schedule to support cash-flow continuity and project momentum in accordance with the Construction Act framework.

Timing as a strategic factor

Because adjudication proceeds rapidly, timing directly affects leverage. Parties must act within compressed timeframes, meaning preparedness often matters as much as — or more than — the underlying dispute itself.

Delay or inaction can weaken a party’s position in several ways:

• disrupting cash flow at critical stages of a project
• limiting the ability to respond effectively during the process
• increasing pressure on downstream contractors and suppliers

The Act’s emphasis on speed is intended to prevent parties from using delay as a tactical tool to avoid payment or resolution.

Consequences of delay or inaction

Missing or postponing key procedural steps can have immediate and practical consequences. Adjudicator determinations are binding on an interim basis, and delayed responses or lack of preparation may result in an outcome that must be complied with right away — even if the dispute is later revisited in litigation or arbitration.

For this reason, the process rewards clarity, organization, and responsiveness. It is not designed to accommodate prolonged back-and-forth or evolving positions over time.

Why early awareness matters

Adjudication is not a last-resort process. It operates during projects, often while work is ongoing and payments are actively flowing.

Early awareness of the applicable time limits allows parties to:

• anticipate how quickly disputes may escalate
• maintain records and documentation in a usable form
• make informed decisions about risk and project management

Understanding the procedural framework before a dispute arises can materially affect outcomes once the process is triggered.
