CROSSING THE BROADWATER Innovation, Risk and Partnering

Abstract

John Holland (JH) is currently delivering Stage 1 of the Long Term Recycled Water Release Plan for the City of Gold Coast (CoGC). This project includes the installation of a 1,800mm diameter pressure pipe over a distance of 1,400m beneath the pristine and well-travelled waters of the Broadwater, between the northern Gold Coast and South Stradbroke Island. John Holland has engaged Bothar Boring and Tunnelling (Bothar) to partner on this extremely complex and challenging pipe drive. The consequences of something going wrong under the waters of the Moreton Bay Marine Park would be dire. The hazards cover the full spectrum of the Project Management process, including Safety, Environment, Quality, Time, Cost, Reputation and Stakeholder Management. Because of this, John Holland, through the assistance of our in House Specialist Trenchless Division, and Bothar Boring and Tunnelling have worked extremely hard to minimize and eliminate where possible the likelihood of each of these risks. This presentation will describe many of the strategies used by John Holland and Bothar to set up the project for success. These strategies include: • Review of innovative technical options • Risk assessments, workshops and close consultation with JH Specialist Trenchless Division • Partnering approach A project such as this can only be delivered successfully when the Specialist Subcontractor and Principal Contractor work collaboratively to manage risks in a considered and methodical manner. This working relationship cannot simply be superficial or transactional, but requires an unparalleled collaborative partnership. This drive could only be successful by truly engaging beneath the surface. Page 1 of 14 No-Dig Down Under 2019 Crossing the Broadwater Wren, M & Barron, P
