eBIM were comissioned by Howarth Litchfield Architects to carry out a full as-built survey of Arnold School in Blackpool using 3D laser scanning. The entire survey was delivered as a full Revit model.
The site is home to a large rambling private school, which has evolved over the years to form a rabbit warren of classrooms, halls and corridors. As Howarth Litchfield are looking to move towards BIM workflows for more of their projects, they opted to use eBIM scan to Revit service.
By utilising 3D laser scanning eBIM could carry out all the site work very quickly, effectively documenting the whole site in less than a week. This allowed the survey work to be carried out in half term minimising any disruption to the students.
Scanning and managing projects of this size requires care full organisation and splitting the site up into clusters and sub clusters that can be managed as chunks. With over 300 scans and 45GB of raw data processing and storing these sized projects requires the latest computer hardware and network infrastructure. Digital run 64bit workstations, with dual CAT6 gigabit connections to our LAN providing smooth transfer of files.
All the modelling was carried out in Revit 2011. As there is no Point Cloud support in Revit 2011, POINTCab was used to generate all the floor plans for the building and Pointools to create clear ortho images. By using a centralised model multiple modellers could all collaborate on the same project seamlessly.
With this project the main hurdle was the large number of level changes within the internal of the building. This made the modelling process very complicated, however by referencing the 3D point Cloud and using our WEBSHARE virtual collaboration tool the entire site could be delivered in Revit 2011.
