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 the outputs for asset verification
Opportunity for infrastructure and external Building projects in digital construction Condition. Last inspected. Invert. Material. Size.
SLIDE 23
BIM and Digital Construction – Opportunity for point clouds
Opportunity for infrastructure and external Building projects in digital construction Use point clouds to verify as constructed models. Detail strategy in BIM Execution Plan (BEP). Quality of delivery. Reduce risk review H&S.

Data Sources
Used in Plain Language Questions PLQ to verify project information on: Environmental Health and safety Constructability Handover verification
SLIDE 25
Closing Thoughts
There is an abundance of free data sources available to use in conjunction with the drone outputs. NI Water have data available for consultants and contractors working on projects 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 Drone technology is making point cloud data more accessible Opportunity to use in planning, design, construction, as built verification, handover to operation
