McIlwain secured this $9.5M contract in October 2015 to increase the existing and future capacity on the Gold Coast road network by converting the existing roundabout at Ross Street and Ashmore Road which serviced more than 42,000 vehicles daily to a signalised intersection.

Works primarily included; road and intersection realignment, road widening, installation of traffic signals, road lighting and ITS, stormwater and drainage infrastructure, new pavements and overlays, signage, PUP removal and relocation as well as soft and hard landscaping.

McIlwain offered DTMR two construction alternatives during the tendering period that provided significant cost and time savings to the retaining wall components of the projects. The accepted alternative was for the construction of a 1,000m2  RSS retaining wall.

Traffic Management was integral to the early and safe delivery of this project.  McIlwain implemented a full weekend closure of the intersection to enable the major pavement construction in the middle of the intersections to be undertaken over a continuous 56 hour period.  The successful management of the detours and the community consultation enabled the construction team to profile the existing pavement and lay over 2,500t of Asphalt and reopen to traffic within the single closure.

All existing and new drainage lines for the project flowed directly to the RACV Royal Pines Resort Lakes with a direct link to the Nerang River the strict management of site runoff and stockpile areas was paramount to protecting the sensitive surrounding environment.

With 42,000 vehicles per day travelling through the project and with over 50 residents within the project bounds Community Consultations and notifications were crucial to successful stakeholder management of this high profile and sensitive project.  24/7 noise monitoring was conducted for the duration of the project to ensure compliance with the strict guidelines outlined in the Compliance Management Plan.  SMS traffic alerts and a dedicated project hotline to provide stakeholders were well informed.

This project has improved road safety for motorists, cyclists and pedestrian while improving traffic flows and reduced travel times. Due to excellent project management and negotiation skills, McIlwain’s project team successfully delivered this project in June 2016 which was completed over three months ahead of schedule and under budget.
