A significant historic house was destroyed by fire in 2017. Our team worked with Mann Williams to provide a high resolution digital twin of the Grade 1 listed building as part of the early £30 million restoration process
OUTCOMES
- UAVs were the safe and reliable way of getting data from the “live” structure
- Fixed the communication and information gaps the as built record for Parnham.
- BIM and Revit outputs were generated shared with other partners
- Enabled the creation of an accurate digital twin for Historic England records
THEIR CHALLENGE
Creating BIM outputs from a dangerous structure
Mann Williams needed to get an accurate set of BIM plans for the remaining structure but access into the damaged parts was not safe for a traditional ground survey. We used an enterprise level drone (DJI M300) with 40MP mapping camera and high accuracy GNSS GPS to create a point cloud and digital model hosted online. This allowed different stakeholders to access quantitative information remotely and to make decisions without having to visit the site. It was also much safer since the building had was unstable and could not be accessed.
Creating the BIM & Level 4 Records
Part of the requirement for the project was to work with Purcell's in Bristol. They are specialist architects and heritage consultants. Purcell's had requested Level 4 records, combined with raw images that could be set up on drawing sheets for issue to Historic England prior to commencement of the restorative works. We worked with Pix4D to produce BIM files and .rcp ready for AutoCAD to pass on directly to the client.
