As part of BHP Billiton's RGP5 project, Underground Services successfully installed an approximate 23km of communications conduit and pits. The project is in the expansion hub of Yandi (100km NW of Newman). The Installation was carried out using trenching machines and excavators.

Mobilisation, staff training and accreditation was carried out in an extremely short timeframe which was complicated even further due to added requirements to modify our plant and equipment as requested by BHP Billiton to meet their exacting requirements. The project was completed on time and under budget with zero incidents.

Telstra, Submarine Cable, Perth

A submarine cable was laid from Singapore to Perth, via Jakarta, by Telstra to ensure sufficient phone and data link capacity, in anticipation of the 2000 Sydney Olympic Games. The $1.7 billion submarine cable links 30 countries across Asia, the Middle East and Western Europe and has the capacity of transmitting up to 250,000 phone calls simultaneously.

Underground Services was contracted to construct the 10 kilometres of secured underground land ducts that would carry the cable through some of Perth's most well-established suburbs, to Telstra premises in the Perth CBD. This project provided Underground Services the opportunity to demonstrate many of its numerous skills. The work included a combination of open trenching, directional drilling, auger boring and micro tunnelling. The ducts traversed high traffic flow intersections, streets and railway lines as well as protected trees, carrying a high degree of difficulty and innovative solutions needed.

Public Transport Authority, Communications and Signalling Network, Perth to Armadale

Underground Services' scope of work was to design and construct an ACA compliant pit and pipe network for communications and signalling cables in the existing "Railway Reserves" on the Perth to Armadale line. Underground Services was also contracted to supply, install and test copper and optical fibre cable and equipment.

The route length was 29 kilometres and a variety of engineering solutions had to be provided including innovative methods for crossing bridges, watercourses and the Swan River.

Underground Services developed a Rail Safety Management Plan and Work Method Statements that met the extremely high safety requirements associated with working in the rail environment.
