Overhead Line LiDAR scanning

Descriptions

Scottish Hydro Electric Transmission Plc. (the "SHET"), seeks a market leading supplier(s) of overhead line LiDAR scanning. The solution will be delivered in PLS-CADD design file and ArcGIS file formats. SHET has identified 4887km of overhead lines in scope for this project, the detail of which will be supplied as shape files readable by GIS software packages. The solution is expected to be a framework for this project and potential future purchases. The solution must provide LiDAR scanning of sufficient resolution to capture the overhead line including sag between transmission structures, the condition of transmission structures, the terrain and surrounding objects to a total width not less than 150m, centred on the overhead lines. Digital stills will be taken of transmission structures and incorporated into the solution such that they can be called from GIS for a particular location. Reference points must be used to accurately position the scanned overhead lines and transmission structures relative to the British National Grid. Post processing must be completed to apply defined feature codes to classify objects and structures captured during scanning. The provider(s) should provide timely high quality project delivery services and excellent post implementation customer support options. The provider should be able to obtain all licenses/certificates required to carry out the work and meet short delivery schedules. To participate in the procedure the supplier should submit a pre-qualification questionnaire on the SHET's source-to-contract system Jaggaer.
