Locating Services

Utility locating is the ability to detect, trace and map underground pipes, gas lines, sewer assets, stormwater drains, telecommunications, electrical and more.

Streets are becoming increasingly congested by underground utilities. Finding and locating these services efficiently and easily is critical to the operations of many businesses.

We at CSA provide underground utility locating services to prevent any damage to existing infrastructure in Melbourne and all areas of Victoria.

CSA Engineers specialise in Subsurface Utility Engineering Practices (SUE). The foundation of our (SUE) business is the collection of accurate reliable utility data in accordance with AS5488-2013 Subsurface Utility Information (SUI).

Our Infrastructure Services:

Underground Utility Mapping

Underground utility mapping is done using a variety of techniques including records research, pipe and cable locators, GPR, sondes, CCTV video capture inspections and vacuum excavation.

An accurate Utility Mapping Survey will give you the confidence to progress with your project and guarantee there are no surprises. It also creates a better working environment for your employees as you are adhering to all health and safety regulations.

We at CSA Specialised Services can help you to identify ‘safe’ areas for excavation, and confirm the safest, and least disruptive route for proposed utilities. Utilising a variety of data sources, we create a complete map of your underground utility networks. Maps can be provided in a variety of formats, from sketches, to CADD to GIS data layers.

Ground Penetrating Radar (GPR)

Ground Penetrating Radar, also referred to as GPR survey is a non-destructive technology that is used to map underground pipes and utilities. This technique is generally cost effective as it reduces traffic management expenses. The data acquisition is relatively fast and generates reliable results.

We at CSA Specialised Services have the expertise and equipment to make GPR a highly effective tool on your projects.
