REAMS was appointed to complete an M&E asset verification survey, a building condition survey and a detailed roof survey utilising our bespoke UAV surveying technology across all of the 50 buildings located on the clients West London site.

The intention of the surveys was to support the Royal Hospital Chelsea with the development of an accurate capital expenditure budget that would improve the estate and to enable their supply chain accurately prepare for the delivery of future project works.

REAMS delivered a detailed assessment across all of buildings, both internally & externally, to accurately assess the life cycle, condition and volume of the building and engineering services elements.  This included the application of QR tags to M&E assets to ensure there was a direct data correlation between the asset in the field and the records held within the clients’ CAFM system.

Due to the listed status of the site, its unique nature, design and age, REAMS opted to utilise CAA approved UAV (drone) technology to replace the traditional methods of surveying high level access items such as roofs, gully’s, chimney stacks, flashing’s, roof lines, and gutters by means of traditional access equipment.

This approach was an innovative alternative to the use of cherry pickers and scaffolding traditionally used to inspect assets at height.  The use of drones is safer and more cost effective for all stakeholders.

The high definition images and scans captured by the drones were reviewed by our surveyors from a desktop position with actions and repairs prioritised and rendered in the overall surveying reporting outputs both in hard copy and through our ELIAS platform.  The surveys were also carried out in the field using the ELIAS mobile surveying application.


  • Carry out a condition survey of the building and services elements
  • Provide life cycle planning and costs for 5 year CAPEX programme
  • Inspect roofs and high level areas using UAV’s
  • Provide data suitable for a bulk CAFM data load


  • Reporting suites produced per building, based on cost & condition
  • 5 year targeted life cycle plans prioritised and budgeted
  • Data analytics were provided, highlighting key focus points
  • Budget certainty and planning for the client and their supply chain
