Construction Sciences is the premier engineering support services business for major infrastructure projects in Australia and New Zealand. With a team of over 800 people, our staff are skilled in areas such as Geotechnical Engineering, Construction Materials Testing, Environmental Consulting and Subsurface Utility Engineering.

Many of the larger project clients engage Construction Sciences primarily to establish a site laboratory to perform Construction Materials Testing, and may add extra service lines such as Geotechnical or Environmental Monitoring. Efficiencies can be found when a large workforce of technicians has been established on a site, and these savings benefit the client.

T2ue provides a full range of Utility Engineering (UE) services including Subsurface Utility Engineering (SUE), utility mapping, CCTV services, Utility Coordination (UC) and Utility Design (UD) to a wide range of public and private clients across Canada and the US.

With modern technology, expertly trained personnel and years of experience, T2ue is able to provide world-class utility services to large-scale, billion-dollar projects and smaller local jobs alike.

Intega’s focus on software enables the business to meet its high-quality standards while employing primary technically trained employees.
