Southern Water S&I - Site Information & Conditional Surveys Framework

Description

Area of interest is Topographical surveys, below ground assets- utility/services identification surveys, unmanned aerial vehicle surveys and above ground assets - point cloud surveys (laser / 3d surveys). Southern Water has carried out a Market Engagement exercise on the Site Information & Conditional Surveys and would now like to invite potential suppliers to respond to this opportunity. This framework is broken down into two lots: Lot 1 - Topographical and below ground surveys Lot 2 - Unmanned Aerial Vehicle Surveys and Above Ground Surveys Lot 1: Topographic surveys Topographic surveys The topographic survey shall be carried out using ground survey methods. The requirements should also cover: - Cabinet - Kiosks - Ground Profiles / cross-sections - Schedule of Permanent Benchmarks used - Schedule of Temporary Benchmarks used - Schedule of Station Positions used The surveys required for utilities are as followed below: - Physical exposure / identification survey - Geophysical survey - Utility plotting from record data - Desktop utility record search Lot 2: Aerial surveys Manned aerial surveys undertaken via conventional aircraft and unmanned aerial vehicle surveys (UAV); the latter referred to in some places as “drone” surveys. The intention is that data would be captured via photogrammetry, but LiDAR surveys may also be undertaken if they meet the project objectives and required accuracies.
