The Royal Festival Hall has been subject to a £90m refurbishment of which the iconic Main Concert Hall was the centrepiece. The project called for the upgrading of the Grade 1 listed fibrous plaster ceilings so that the acoustic performance within the hall would be acceptable for the 21st century.

Clark & Fenn Skanska researched and developed an innovative solution, along with architects Allies and Morrison, to produce a GRG profile to an overall 100mm solid thickness to accommodate the clients acousticians specified performance. The various GRG elements were manufactured in the companys workshops and installed by skilled craftsmen supervised by one of the companys senior site managers.

AIS Awards Judges commented:
One of our joint Gold Award winners in this category, the ingenuity evolved in achieving the acoustic control specification and the logistics of installing this one off makes it a worthy winner.
