Extension of time (EOT) and delay claims under the GC21 contract require more than just pointing to a hold-up and expecting more time. Whether you’re a contractor, subcontractor or principal, understanding the steps and documents involved can make the difference between a successful claim and an end-of-project dispute.

The construction industry in New South Wales has seen major reforms in recent years. Central to these is the introduction of the Design and Building Practitioners Act 2020. Brought into force in 2020, the legislation was created to address long-standing concerns about defective buildings, gaps in accountability, and a lack of confidence in the industry.

How long do construction disputes take?

There is no one-size-fits-all answer to this question; the timeframe to resolve a dispute can vary wildly depending on the nature and complexity of the legal matter. 

A key factor in all of this is the forum you choose to resolve your dispute:

  • The timeline to resolve an adjudication under the Building and Construction Industry Security of Payment Act is typically measured in weeks, up to a couple of months. 
  • Matters before a court can take much, much longer, and it isn’t uncommon for parties to spend years in the court system before a resolution. 
  • Other mechanisms (negotiation, mediation, etc.) rely heavily on the other party and their willingness to seek a resolution – motivated parties can meet a resolution as quickly as they can agree, where a dispute against an intransigent counterparty will often take much longer. 

This highlights the need to pick the right dispute resolution mechanism for you and your issue. 

Recovery against an insolvent party can become much more complicated. While you may be able to recover some of what you are owed, in a lot of insolvency cases, your chances of full recovery are lower.

There are steps that you can take to increase your chances of a more favourable result.

These potential steps include:

  • File a proof of debt with the appointed liquidator. This allows you to register your claim for any unpaid amounts owed.
  • Understand the rights in your contracts, and whether there are any clauses (such as retention of title) that could assist.
  • If a personal guarantee is provided by an individual related to the insolvent company, there may be other, more fruitful avenues to pursue payment.
  • Considering your entitlement to submit a subcontractor’s charge over money owed to your debtor from a third party.

Insolvency law is complex, and as a result, it is essential to seek out legal advice. An experienced construction law specialist can help you navigate the process and map out the most advantageous route to a fruitful outcome.

It is often a bad idea to ignore any claim made, irrespective of how much merit you think it has. While every matter warrants its own strategy, ignoring claims can be a quick way to have a court, adjudicator or other decision maker determine that you have accepted, or are deemed to have accepted, the claim. 

If you have received a claim you disagree with, no matter how baseless, it is worth consulting with us on strategies to avoid that claim becoming a debt.
