Pinpointing the exact location of utilities is vital when planning and undertaking both design and construction work. Underground Utilities Mapping and Topographical Surveys by Plowman Craven provide a comprehensive understanding of infrastructure above and below ground.
We offer a wide range of utility mapping solutions – tracing, identifying and mapping all utilities and service routes including gas, water, telecommunications, electricity and drainage, using the latest innovative technology and tracing methods.
As the only Thames Water-approved survey company in the South-East, Plowman Craven can provide a range of sewer survey deliverables including Line & Level and Non Man-Entry surveys.
We also go beyond the traditional 2D mapping of services. When combined with our leading topographic surveying capabilities, our utility tracing methodologies provide a comprehensive 3D understanding of infrastructure above and below ground.
Producing topographical surveys for greenfield, brownfield and development sites, data is captured in either 2D or 3D using the latest Total Station, GPS, laser scanning and UAV technology, applying innovative terrestrial, mobile and aerial techniques.
Our utilities team uses a state-of-the-art dual frequency radar unit (IDS-Duo) that can simultaneously scan two different levels, enabling us to record depths of 0-1m (higher frequency) and 1-3m (lower frequency) at the same time, saving a great deal of time and money.
Our UGS teams also undertake CCTV condition survey of drainage networks, lifting all manhole covers to identify and measure the content using a high definition video camera that is inserted into each pipe, noting defects, blockages and damage encountered. The CCTV surveys are part of the UGS work but are delivered separately – as a series of videos, one for each run surveyed, and also as a report detailing the defects and condition.
