Projects

Geotechnical Assessment

The client, a Geotechnical Assessment company, requested a ground investigation to ascertain the location of a Basalt Rock Layer Escarpment. We were able to obtain Radar Images of the Basalt Layer and provide the client with a detailed report including radar imaging photos.

A local government authority

engaged Geoscan to locate a master control unit within a buried irrigation control valve box. The irrigation system had been unused for around 12 years. Using ground penetrating radar (GPR) imaging, we were able to detect the valve box beneath the surface. Once exposed, the system was reactivated.

This photo shows the GPR equipment with ground markings indicating the position of the located valve box.

Electrical Fault

Geoscan was engaged to locate a fault in a mains cable supplying a TAFE college. Testing showed one phase had failed, cutting power to a key building that housed critical computer and data systems essential for administration and campus operations. Rapid detection and pinpointing of the underground fault was vital to restore electricity and ensure minimal disruption.

Al Taqwa College

Geoscan was engaged by Al Taqwa College to survey key areas of the school, focusing on the precinct around the Mosque. The work involved identifying and mapping stormwater and sewer infrastructure, much of which was hidden by old slabs and redundant services.

Using Ground Penetrating Radar, service locating, and rodding, Geoscan systematically traced and confirmed the full network of subsurface utilities. The survey resolved longstanding uncertainties and provided the architects and engineers with a clear foundation for planning future buildings. The project was completed on time and within budget, highlighting Geoscan’s precision and problem-solving approach.

Gheringhap St Geelong, Ausnet / Downer

Geoscan was engaged by AusNet and Downer to carry out a heritage drain inspection from Johnstone Park to Corio Bay, in support of the proposed Gheringhap Street development. The focus was a 1.7m brick oval drain, with the aim of identifying all feeder lines to assess flow capacity and plan for the relocation of intersecting services.

We marked all findings on the ground as per AS5488:2022 standards, ensuring surveyors could accurately map and record the data. This approach provided a comprehensive overview of the drainage network, enabling effective planning and integration with the proposed new buildings along Gheringhap Street.

GMHBA Stadium drainage investigation

Geoscan was commissioned to investigate drainage issues at GMHBA Stadium following incorrect level data. The primary task was to locate a heritage-listed brick-arched drain running through the Geelong CBD, discharging into the Barwon River.

Using Ground Penetrating Radar (GPR), we determined the depth to the top of the drain to ensure it was protected during upcoming stadium upgrades. Our detailed investigation provided the necessary information to safeguard the drain from potential damage and to inform the planning of the stadium’s infrastructure works.

Bulla Dairy Trade Waste and Sewer Investigation

 Geoscan was engaged by Bulla Dairy to locate and survey the trade waste, drainage, and sewerage systems at their Colac facility. Over the years, numerous incorrectly installed pipes and pits had led to trade waste being unintentionally discharged into both stormwater and sewer networks — a serious environmental concern.

To address this, Geoscan meticulously rodded and camera-inspected the entire network, accurately determining invert depths, pipe sizes, and pit cover levels. Our team worked in tight spaces around the live ice cream factory, ensuring minimal disruption while capturing essential data on all runoff paths.

The results of our survey provided Bulla Dairy with the insights needed to redesign their drainage network, ensuring proper containment of trade waste and resolving the cross-contamination issues between stormwater and sewer systems.
