Gateway Motorway

The Gateway Motorway is the main North-South arterial route for the north of Brisbane. An upgrade was planned to ensure traffic flow to the airport. Maxwell GeoSystems brought two new data concepts to the project which was delivered almost a year ahead of schedule.


Project details

Client: Leighton AbiGroup
Queensland Roads

Budget: Aus$2.12 Billion

The alignment traversed a number of areas of soft ground and given the tight programme time-line the Leighton Abigroup team sought ways to achieve consolidation for the earthworks within the shortest possible time.

An observational method was proposed and Maxwell GeoSystems were tasked with providing the systems to make it happen.

Maxwell GeoSystems brought two new data concepts to the project. Firstly, instrument groups in which a number of instruments could be used to define new "virtual" instruments of particular engineering significance.

Secondly a series of prediction instruments for tracking performance. By providing this novel approach to the connectivity of project data, Maxwell GeoSystems made a valuable contribution the project which was delivered almost a year ahead of schedule.

What the Client says about our INSITE and services:

INSITE was selected on this project, in part for its ability to be customised and present monitoring data in a format that enabled LAJV to adopt an observational approach to the construction works. This approach required a fairly intensive monitoring regime, with a large volume of survey, inclìnometer and piezometer readings taken. INSITE was able to quickly process this data and present in a graphical format for daily engineering review by the Designer to ensure stability and safety of the works.

Due to large settlements experienced on the project and the number of monitoring instruments installed this created a large amount of readings and data input into the database. The INSITE System and Maxwell Geosystems were responsive in providing a robust database to handle this large data and ongoing technical support both remotely from Hong Kong and on-site to resolve any software or data input faults in a timely manner that did not impede construction progress.

As a result of the successful implementation of the monitoring instrumentation and INSITE database, LAJV and the Geotechnical designer were able to review the data daily so as to ensure that settlement of the embankments did not exceed design requirements. It also made it easier to remove the surcharge/preload material at the end of the settlement period.
