Know the Drill - Issue 3, 2023

Welcome to issue 3 of Aon Construction’s Know the Drill for 2023. In this issue, we focus on three topics:

  • Retention Amendments

  • BDO Annual Construction Survey

  • Construction Contract Works Insurance – State of the Market

Retention Changes

Amendments to the Construction Contracts Act (CCA), regarding the management of retentions, were passed on 5 April 2023 and take effect from 5 October 2023. 

The management, reporting of retentions and fines for breaches of the CCA clearly falls to the Principal (in contract with the head contractor) and the Head Contractor (in contract with their sub-contractors).

Many leading construction lawyers have put out summaries on the changes, as well as MBIE. Visit: Changes to retention money requirements | Building Performance

The good news is the Aon Retention Instrument still remains a complying instrument under the CCA.  The advantages of the Retention Instrument are numerous but the main one is that it works by protecting a specific dollar amount of retentions so that it is not necessary to hold retention money on trust in the form of cash, freeing these funds u so that they can be used in the business.
