In order to combat the increased occurrence of excavation related accidents and damage to utilities caused through construction activity the HSE Executive has published guidelines with respect to avoiding such danger (reference HSG47). Recommendations include the use of location devices for the sub–surface detection of utility infrastructure.
LandScope has developed a full utility and service mapping service of which various levels may be selected by the customer depending on specific survey requirements.
A typical survey would comprise:
Our underground infrastructure surveys are increasingly used during the project design stage so that appropriate measures are taken to avoid service conflicts and quantify the scope of any service re–alignment works.
Radio detection and ground penetrating radar techniques are also used to confirm and complement existing as–built drawings and other records prior to development and excavation operations. LandScope's robust and thorough field procedure employed with the dual technology approach – Radiodetection and GPR – ensures that our customer's benefit from the best available results.
Survey results can be delivered in a variety of formats from surface marking to 3D AutoCAD® geo–referenced drawing files.
LandScope offers a comprehensive CCTV open pipeline inspection service. Utilizing a digital pushrod or advanced 'tractor' system fitted with radio–sonde device, we are able to locate and inspect underground pipelines and ducts from a minimum diameter of 2" (50mm). In–field inspection of the pipelines and ducts can be performed on a real–time high resolution display or, alternatively, the data may be saved, catalogued and formatted to be subsequently reviewed in greater detail.
