TOOWOOMBA Second Range Crossing constructor Nexus is preparing the site for major construction activities expected to start in coming months.

One of the pre-construction activities under way is the excavation of road surfaces.

That involves workers identifying the locations of existing public utility services on roads and footpaths.

Geotechnical investigations are also taking place.

Workers are drilling to collect more information about soil and rock types to help evaluate ground conditions.

Survey work is also taking place across the project corridor.

The various soil types on the project site are being tested using a process called test pitting.

It is undertaken to determine the characteristics of soil types, which are then taken into account in the project's design and construction.

It involves excavating a sample area for testing.

There are three crews working at present, each with a geologist and a machine operator.

Work is under way at locations along the project corridor, including at Murphys Creek Rd in Ballard, and Mort St and Hermitage Rd in Cranley.

A site on the Gore Hwy at Athol is also being tested.

Geotechnical investigations are being done off Jones Rd in the Upper Lockyer Valley where an 800m-long viaduct will be built to provide a link between the Lockyer Valley and the cutting through the Toowoomba Range at Mount Kynoch.

This work is due to be completed by mid-February, weather permitting.

The tendering process for the project is continuing with expressions of interest called for the supply and installation of UV filters, rumble grids and electrical and plumbing maintenance services.

Nexus Delivery is encouraging local industry interested in supplying to the project to register an expression of interest through the ICN Gateway website at

Other contracts on offer include hiring of cranes, supplying labour hire and providing survey services.

The $1.6 billion project, which will create about 1800 jobs, is expected to be completed by late 2018.
