Kilcummin
PROJECT OVERVIEW
AltiGeo was appointed to complete a topographical survey, measured building survey, and Scan-to-BIM package for Our Lady of Lourdes Nursing Home in Kilcummin, Kerry.
Survey Method
The survey required careful planning due to the operational nature of the nursing home. The building was arranged over two floors, requiring a coordinated approach to capture both internal and external areas accurately while working around access availability, staff movement, resident privacy, and the day-to-day running of the facility. Before entering any resident room, an attendant first checked that the resident was comfortable for the survey team to enter. This ensured that resident privacy, dignity, and comfort were maintained throughout the survey process.
The topographical survey was completed using a Leica TS16 Total Station and Leica GS18 GNSS, capturing site levels, access routes, parking areas, boundaries, external features, and surrounding context.
LiDAR Scanning
External laser scanning was carried out using a Leica RTC360, with survey targets used for geolocation, registration, and cross-checking of the pointcloud data. Internal scanning was completed using a Leica BLK360, capturing the two-floor building layout, corridors, rooms, stair cores, openings, and key architectural elements.
Corridor and bedroom scans were carried out during breakfast and lunch periods, when movement through the circulation areas was reduced. This allowed the survey team to work safely and efficiently while maintaining privacy, comfort, and minimal disturbance within the occupied nursing home environment.
To improve visibility and safety, the scanner tripod was covered with a high-visibility vest so that residents and passers-by could clearly see the equipment and avoid accidental contact.
A total of 688 LiDAR scan setups were recorded for the project. The scan data was registered and processed in Leica Cyclone REGISTER 360 PLUS to create a coordinated LiDAR dataset for the project.
CAD & BIM Production
The coordinated survey dataset was used by AltiGeo’s CAD and BIM team to produce accurate 2D CAD drawings and a BIM model of the existing nursing home.
