March 7, 2024

In 2023 NZS3910, the industry standard form of contract for building and civil engineering projects, was revised to include several provisions to make it more user friendly, clearer as to the roles of the parties. including the splitting of the roles of Contract Administrator and independent certifier and the introduction of plainer wording. It is hoped that these changes will assist with the commercial control of projects, which will in turn reduce the number of costly disputes. It is essential that industry gets up to speed wirh the new form as the number of disputes under the 2013 form is at its highest, given the strains on the industry at present. This course will run through the essential changes to NZS3910 and provide advice and interpretation of the role of the independent certifier, early warnings, variation priceing and other major changes in the document, so that all stakeholders are equipped to understand their contractual obligations, take control, and avoid disputes. It will also cover the impact of the CCA (Retention Money) Amendments Act 2023 on Construction Contracts and good commercial practice guidance.

As New Zealand has entered a period of significant construction constraints, making it harder for everyone in the industry to navigate, it is important that professionals, prinicpals and contractor alike understand the effect of the number o changes in respect of the new form. Understanding these will assist the parties to a contract deliver a project on time and on budget.
