Royal Society of Medicine, commercial ceiling reinstatement delivered by Nationserv
Case study, commercial major loss

The Royal Society of Medicine, London.

Appointed following a leak from offices above. Damage was sustained to the auditorium and reception ceilings of a prestigious, fully operational venue with fixed arced seating, hardwood flooring, ceiling hung lighting rigs and a built in projection screen. The challenge was not the repair. It was the protection.

A bespoke internal scaffold was designed and erected over several days. Layered protection in foam, polythene and Correx shielded every fixed installation. Plaster ceiling repairs, specialist ornate preparation and spray decoration were delivered throughout, with no secondary damage to any feature of the building.

This project demonstrates our ability to work within some of the UK's most sensitive commercial environments. By combining technical expertise with careful planning and on site control, we ensured a right first time result with no impact to the building's critical infrastructure.
