Project: Jewel Fine Foods
Project scope was to retrofit a 10,760m2 existing warehouse to host a food processing and packaging plant.
Project facts: -
Existing structure scanned: 10,760m2 (approx. 140,000m3 of scanned data)
Scan size: 505 million points captured in 4 hours.
Layout points (steel drillings): 1056 (1 day on site)
Layout points (concrete chemsets): 464 (1 day on site)
Assemblies retrofitted: 3419 assemblies supplied to be erected
Software used: Tekla Structures v2016, Trimble Realworks v10.1, Trimble Connect, Tekla BIMSight
Hardware used: Faro X130 scanner, Trimble Robot Total Station
Drawings: 1340 assemblies, 1877 parts, 98 general arrangements
3D scan utilised and over 505 million points taken to capture the internal objects within the warehouse including:
Existing service pipes/fire water
Electrical cable trays
Concrete step downs and joints
Precast walls slabs.
CSD Group Australia Pty Ltd was initially engaged to shop detail the new retrofit steelwork to fit out an existing warehouse into a food processing plant.
Upon inspection of the building and kick off meetings at site, CSD Group was further engaged to undertake the BIM collaboration and the 3D scan to BIM for the existing structure.
Initial 3D scanning showed that the cambers were not added during the construction of the original building, causing some rafters to sag over 110mm in the middle, and were bowing in the horizontal axis by up to 35mm.
Additional column steelwork was immediately supplied to rectify the structural rafters. We utilised the 3D scan to determine how much each column had to be jacked up once positioned to correct the rafters in over 100 locations. Once complete, a correction check survey was done to ensure the building moved as we intended.
Using the 3D scan, we modelled in all additional steelwork, using macros/details with pre-positioned layout points to connect the existing steelwork and concrete. All steel lengths between existing rafters were bespoke as no allowance for slotted holes were allowed to the hanging equipment frames and the rafter corrections did not allow to rectify the horizontal bowing of steelwork.
Skype for business and drawing imports were utilised alongside Tekla BIMsight and Trimble Connect to bring in the new refrigeration components, aircon ducting and services to ensure no clashes would occur on site, and furthermore that no clashes would occur with existing fire water piping and cable trays which were taken from the 3D point cloud.
During the approval stage, whilst the 2D drawings were starting to be processed, two CSD Group team members spent two days on site with an RTS unit using points taken from bolt locations to existing steelwork and new chemset locations within the 3D model. CSD Group laid out over 464 chemset locations for the column baseplates and 1056 bolt locations to existing steel rafters 13 metres in the air!
Once the steelwork arrived on site, all 3419 new assemblies fit to the 1520 site marked holes with millimetre precision and required no site alterations.
