Shortening the project from 120 to 42 days

Interstate 25, a major highway through Colorado, has some of the oldest segments of freeway in the state. It was originally built in the 1950s and no efforts to modernise it were made until recently.

The Colorado Department of Transform (CDOT) selected a local construction firm, Scott Contracting, for portions of the project. 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.

For 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. 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. To do this they used the LOADRITE system.

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.

Having the latest version means you have the software’s latest features and advances, plus solutions to any known bugs. The most up-to-date software version for Trimble LOADRITE® Communications Controller (LCC) units is v2.01.0002.

It is highly recommended that any new LCC installs are updated to the latest software version prior to installation, and existing units in the field are upgraded as soon as possible. A number of bug fixes have been resolved in recent releases and the reliability of the LCC is significantly compromised by not upgrading.

Efficiency helps complete earthworks project early

georgiou-250x150When 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. 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. The site measured 2 kilometers long by approximately 600 meters wide. To get a better understanding of payloads, movement of material, and the productivity of operators and mass haul routes, Georgiou turned to SITECH WA.

In the past, Georgiou manually collected payload data to map to cost centres. They had no access to real-time data on productivity and material movement leading to potentially inaccurate and sometimes delayed information.

On this project, the team adopted a range of Trimble® solutions including: the 3D GCS900 Grade Control System, 2D Project Monitoring on Haul assets and LOADRITE X2350 excavator scales. Data from this hardware was used by InsightHQ and VisionLink® software to improve productivity, increase data transparency and accuracy, and therefore reduce costs. Georgiou used Business Center – Heavy Construction Edition (HCE) software for Mass Haul Analysis and Design Creation.

Georgiou saw benefits in the following areas

  • 33% project time reduction and 25% hauling productivity gain through transparency of payloads
  • Real-time visibility of cost to move material, load times, and other vital production data
  • Quickly-defined optimal haul zones using Business Center – HCE
  • Ability to monitor where material was removed and dropped
  • Improved productivity with access to accurate, automatic production and volume reports

Advanced earthworks solutions result in efficiencies

RingRoad-SeymourWhite1The alignment for the dual carriageway for the Townsville Ring Road Section 4 project is across old swamp land, which means all materials will need to be imported from local quarries. The key to success for this project is the speed at which fill can be imported and compacted.

This challenge drove the team at Seymour Whyte to develop a unique combination of advanced solutions that have resulted in constant visibility and tracking of progress across all activities including construction, extraction, haulage and placing of materials.
