NI Water and Drone Technology – knowledge share event

Welcome Mike Shaw Managing Director RPS

NI Water and Drone Technology Agenda • 09:30 – 10:00 Registration • 10:00 – 11:00 Drone technology for topographical surveys. • Overview of the UAV Technology. • Safety and legislation on the use of UAV’s • Planning the survey • Ground control points • Flying the area to be surveyed. • Geotagging images. • Processing the images and adding ground control data. • Outputs. • 11:00 – 11:15 Coffee and Tea Break • 11:15 – 12:00 Using the drone outputs in BIM authoring and model aggregation software. • Processing of the raw data. • Using technology to: • Crop and select. • Build terrain models. • Ascertain volumetric calculations and production of other outputs. • Federating with other authoring technology. • Application of drone technology in BIM projects • Site Surveys and early planning. • Using as asset verification.

Using Drone outputs in BIM Authoring and Model Aggregation Software David Gawley BIM Consultancy Director

Outputs Georeferenced Mosaic Digital Surface Model – 382 MB DXF File – 170MB (DSM) – 310MB, 2G ASC Other Formats: LAS, xyz process to a point cloud

Comparison OSNI\LPS Data UAV technology – 2.5cm 1 Pixel – 16cm 1 Pixel – 16cm 1 Pixel – 30cm Changes in positional accuracy

BIM and Digital Construction – Opportunity for point clouds Opportunity for infrastructure and external Building projects in digital construction Detail strategy in BIM Execution Plan (BEP). Quality of delivery. Reduce risk review H&S. Use point clouds to verify as constructed models.

Data Sources Used in Plain Language Questions PLQ to verify project information on: Environmental Health and safety Constructability Handover verification

Closing Thoughts NI Water have data available for consultants and contractors working on projects Drone technology is making point cloud data more accessible There is an abundance of free data sources available to use in conjunction with the drone outputs. Most software technology can accommodate the files and data for civil engineering surface creation and even conversion. Opportunity to use on quality of delivery on Infrastructure projects, reduce risk and provide early answers to design information Opportunity to use in planning, design, construction, as built verification, handover to operation
