Locating buried services in Glasgow city centre

As part of a major redevelopment of several educational buildings in Glasgow city centre Phase Site Investigations were called in to utilise their expertise in detailed utility tracing surveys.

The redevelopment required several stages of intrusive work in the roadways surrounding the buildings, including excavating a number of boreholes and trial pits prior to the redevelopment and then the installation of new pipes and cables and other infrastructure during the construction of new buildings.

The client recognised that a detailed utility tracing survey at the start of the project would minimise the risk of damaging existing services during the intrusive investigation work and that this information could also be used to assist in the design and positioning of the new infrastructure.

Phase SI carried out radio frequency location (RFL) survey to trace metallic cables, pipes and drainage routes followed by a detailed ground penetrating radar (GPR) to locate non-metallic apparatus and any additional sub-surface hazards.

The high precision equipment utilised by Phase SI coupled with the experience of our operators meant that accurate mapping of highly congested utility routes could be undertaken. The survey was carried out with minimal disruption to the public and unexpected hits for future intrusive work can be avoided, reducing potential costs and disruption that could otherwise have occurred. The design and planning team now also had an accurate map of the existing services on which they could base their design.
