Subsurface Utility Engineering (SUE) is an engineering practice that has evolved considerably over the past few decades. SUE allows cost effective location and depiction of the exact location of underground utilities through the interaction of technology, civil engineering and geophysics. The combination of cutting edge technologies and innovative practices are managed by TST Engineering to avoid characteristic risks of normal intrusive works carried out when locating underground utilities.

This leads to saving time and money while avoiding the possibility of dangerous consequences and/or interruption of existing utility services. A detailed analysis is performed and delivered in the customized form of the Clients’ request; a wide range of layouts are available, including simple mark-out on site to geo-referenced 2D and 3D rendered maps.

Thanks to this information our clients are able to:

- Avoid risks and accidental damages to buried utilities;
- Pre plan possible diversion of utilities;
- Project new underground networks.

TST Engineering Group operates Subsurface Utility Engineering achieving the highest level of accuracy on underground mapping as described by the American Society of Civil Engineers. The PAS 128:2014 is the “Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data” and it represents a document that defines the quality of utility location. The classification is operated through four different levels, from D to A. From the lowest one (Level D) which is based from information derived from existing records, to the highest one (Level A) which determines the absolute precise location of buried utilities. TST Engineering Group is committed to provide information that complies with the Quality Level A of the PAS 128:2014.
