The site measured 2 kilometers long by approximately 600 meters wide. The six-month project in Alkimos, Western Australia, involved moving 600,000 cubic meters of sand, rock and limestone 1.5 kilometers between the cut and fill zones. When Georgiu Group, a national building construction, engineering and property development company, were awarded a land development project, they took this opportunity to review their productivity and cost control.

See more of Scott Contracting’s project successes in the full case study on the Trimble website. Scott met its goal, removing and replacing 23 411 square meters (28 000 square yards) of 28cm (11-inch) concrete paving, and performing another US$1.2 million of added work within the same time frame. To do this they used the LOADRITE system. Scott instead proposed a fast-track method, shortening the project from 120 to 42 days and resulting in a total cost savings of US$500 000. This included the bridge work, removing and rebuilding six bridges along 3.2Km (2 miles) of highway, and moving around one million tonnes of material.įor removal and replacement of three of the four on and off ramps at a busy intersection, the contract allowed 120 working days in 12 phases. The Colorado Department of Transform (CDOT) selected a local construction firm, Scott Contracting, for portions of the project. It was originally built in the 1950s and no efforts to modernise it were made until recently. Interstate 25, a major highway through Colorado, has some of the oldest segments of freeway in the state. If you want to know how SITECH Construstion Systems can help with your next project, give us a call 0800 4 SITECH The project is a partnership between the Victorian Government and Transurban and will be built by construction contractors CPB Contractors and John Holland (CPBJH JV).Ĭonstruction is under way, with the new road to be opened in 2022.
The West Gate Tunnel Project will deliver a vital alternative to the West Gate Bridge, providing the city with a much-needed second river crossing, quicker and safer journeys, and remove thousands of trucks from residential streets.
Depending on the ground conditions, the machines will typically bore an average distance of 9m per day. The TBMs will excavate over 1.5 million cubic metres of rock and soil.
Using covered conveyors, the rock and soil from the Tunnel Boring Machines (TBMs) will be moved to the spoil management facility, where the four excavators will load the material onto trucks to be transported offsite to suitable fill sites.Īll the load data will be sent via Trimble InsightHQ back to the project team for daily reports that will detail every bucket loaded and how many tonnes of material have been loaded. SITECH was approached to provide a solution to enable the project team to accurately manage the amount of material loaded on to trucks leaving the site to ensure that they were not overweight and were safe to use the public road network. SITECH Construction Systems recently installed four Hitachi ZX490LCH-5 excavators with the Trimble LOADRITE X2350 Payload System, to be utilised on the West Gate Tunnel Project currently under way in Melbourne. One of Victoria’s major infrastructure projects has added a new level of accuracy to its operations thanks to Trimble and SITECH.
