Jacob's Inn Hostel
PROJECT OVERVIEW
AltiGeo was appointed to complete a measured building survey of Jacobs Inn Hostel, located in Dublin City Centre. The hostel contains close to 60 rooms, along with circulation areas, common spaces, staff areas, and external building elements, all of which required careful coordination due to the building being operational during the survey.
Survey Method
A survey schedule was agreed with hostel management to allow the internal survey to be carried out efficiently while maintaining the privacy and comfort of guests. The survey of each room was carefully timed, with the maintenance team first checking whether the room was available before the survey team entered.
Common areas and corridors were scanned early in the morning between 4:00am and 7:00am, when guest movement, check-ins, and check-outs were limited. The majority of bedroom scans were completed during the interval between guest check-out and check-in times, allowing the team to capture the required survey data with minimal disruption to hostel operations.
LiDAR Scanning
External laser scanning was carried out using a Leica RTC360, while the internal survey was completed using a Leica BLK360. Black-and-white survey targets were used for geolocation.
The scan data was then processed and registered to create a coordinated pointcloud dataset of the full building.
CAD Production
The coordinated survey dataset was used by AltiGeo’s CAD team to produce accurate measured building survey drawings of the hostel. The drawings were developed from the registered pointcloud, providing a reliable as-built record for the client and design team.
