Welcome to the 27th issue of BuildLaw® in which we draw on the experience and expertise of leading experts in the field to bring you commentary, articles and reviews on topical matters relating to construction law. In this issue we feature new changes to the Construction Contracts Act – the new statutory trust model for retentions which came into force on 31 March 2017 including the late introduction of a ‘complying instrument’ option as a means of protecting retention money. We also look at public sector procurement, peer professional opinion defences in negligence cases in Australia, the consequence of skipping a mandatory pre-arbitral step, extensions of time anomalies in relation to subcontracts, post termination calls on on-demand bonds, managing earthquake prone buildings; and more. In ‘Case in Brief’, Sarah Redding discusses a recent appeal against an arbitral award made pursuant to a NZS3910:2003 contract and I look at a recent Court of Appeal judgment that dealt with the requirement to ‘indicate’ a claimed amount in respect of a contract where no price or payment mechanism was agreed. I wish to take this opportunity to thank all our contributors. We are most grateful for the support we receive from dispute resolution professional, law firms, and publishers, locally and overseas, that allows us to share with you papers and articles of a world class standard, and to bring you a broad perspective on the law and evolving trends in the delivery and practice of domestic and international dispute resolution and construction law.
