Bristol Old Vic Theatre, Bristol, UK

Built in 1766, this 18th century Grade 1 listed Georgian theatre is the oldest working theatre in the UK. The HI-FOG® system was installed during a complete refurbishment of the theatre, with the tubing installed within some very tight spaces of the building fabric. Throughout the building the sprinkler heads had to be positioned to meet both the system design criteria and exacting architectural heritage constraints, especially within the auditorium decorative ceiling where the sprinkler heads have become a subtle and integral part of the pattern.

The Old Vic Theatre Project was an ongoing National Lottery funded refurbishment programme. The client had originally planned to extend the traditional sprinkler system but this was not practical for the fabric of the building because of the large pipe sizes that go hand in hand with that type of system.

HI-FOG® protects the heritage part of the theatre, which includes the seating areas, the Royal Box and the wooden beamed roof space which is open to public viewing. Basement plant areas were also at a premium, making the installation of the modular MSPU4+1 pump unit, control panel and sectional water storage tank an ideal solution.

The project recently won the ’Heritage Project of the Year’ award at the CIOB/South West  Building Excellence Awards and has been entered into the forthcoming National Awards.
