Bosch Munitech’s ‘Underground Services Location’ facility provides reliable information on buried utility infrastructure layouts

Bosch Munitech’s specialised Underground Services Location (USL) facility encompasses advanced utility detection and mapping services, essential for providing accurate information on buried utility infrastructure layouts.

“USL – which requires expert skills, using non-intrusive methods to locate the exact type, size, position and depth of buried utilities – is critical in reducing risk and ensuring efficiency and safety in every excavation or construction project,” says Chris Otto, divisional head: underground services and leak detection, Bosch Munitech, part of Bosch Holdings. “Before digging commences, it is vital that all buried utilities likely to be affected by excavation or construction, are located. Underground utilities unexpectedly encountered during excavation, could cause costly delays of the project, the disruption of essential services and the injury or death of workers.


“Bosch Munitech uses advanced equipment, including electromagnetic locators, ground penetrating radar and sonde tracing, to locate buried services. These include water pipes, storm water and sewerage drains, as well as electrical, telecommunications and fibre optic cables. These utilities are then surveyed by engineering surveyors and draughted onto AutoCAD 2D and 3D drawings.”

Bosch Munitech’s services are custom designed to suit the specific USL requirements of consulting engineers, environmental specialists, construction and mining companies, municipalities, small civils and industrial plants.

For example, the smaller contractor who needs to avoid buried services during excavation, only requires scanning of a small area for underground services, to indicate the position of existing services, without having to identify the type of service.

The company’s full USL facility – which is necessary for planning new pipe designs, utility diversions and new construction – involves the latest non-intrusive techniques to establish, not only the position and depth of buried utilities, but also the type, size and origin of underground services.

By gaining access at points, like chambers and sub stations, the type and size of services can be identified. Individual routes of cables can then be traced by inducing target signals onto target lines.

Key benefits of utility detection include accurate utility drawings for design purposes, less damage caused to essential services during excavation, reduction of costs caused by services damage, re-designs and interruptions and a safer working environment for field staff.

Bosch Munitech’s utility detection and mapping services, which were launched in Gauteng six years ago, are now offered throughout the country, from USL branches in Johannesburg, Durban and Cape Town.

The company’s utility management solutions also include water and wastewater, operations and maintenance, solid waste management and geographical information systems.
