wagamama Flagship Restaurant
Designer: Focus Design, Winchester
Contractor: RTS Contracts
C Caswell Engineering Services were appointed as the HVAC specialist on this flagship project in St Andrews Square. Centrally located in one of Edinburgh’s most prestigious locations within the hub of Edinburgh’s financial centre, Princes St and the City’s iconic Waverley station.
This 220-seater restaurant is arranged over Ground and Mezzanine floors and a key feature is the exposed Kitchen Canopy and ductwork which can be viewed from anywhere in the restaurant.
Caswell’s full HVAC system design, manufacture, installation and commissioning service included:
- Kitchen ventilation incorporating Caswell Kitchen Canopy, odour control, fans, medium pressure ductwork (to BESA DW172 & DW144) and attenuators
- Non-coated Fire Resisting Ductwork (to BS476:Pt24)
- Tempered Supply Air system
- WC and general ventilation system
- Mitsubishi ‘split’ air-conditioning system* with fan coils and supply air grilles located in the restaurant (*Caswell are a Mitsubishi Business Solution Partner)
- An HVAC Control System was designed and installed to provide full operation of all services from a single panel
The project commenced on site in January 2017 and handover was in April 2017 so timescales were tight. Working alongside James Hamilton - Director at Focus Design - a number of other challenges were overcome, including:
- A very restricted void space around the kitchen
- Strict noise criteria and odour control requirements, due to a Penthouse flat in close proximity to the Kitchen extract discharge
- A stringent Building Fire Strategy requiring the kitchen extract ductwork to be Fire Resistant
Caswell are experienced in ‘fast track’ projects and Jack Bennett was our Project Manager on this one. Aided by Caswell’s design & programming capabilities, in-house ductwork and canopy manufacture and the full resources of committed and capable ‘Team Caswell’ members, the project was completed smoothly and on-time.
All HVAC Services were designed using the latest 3D software to enable us to apply state-of-the-art modelling techniques prior to manufacture. A noise report was commissioned to allow appropriate noise reduction methods - such as anti-vibration ductwork hangers and attenuators - to be factored in to the final specification.
Working closely with our supply chain we designed appropriate filtration and odour control systems incorporating Baffle filters, Electrostatic filters and an Ozone injection system. Careful consideration was given to the location to ensure that cooking fat, carbonised particulates and odour were removed close to source, so keeping the majority of the downstream ductwork clean.
The fan coil ductwork was neatly distributed through the existing castellated beams and condensers located at the rear of the building on a purpose-built gantry
As the exposed Kitchen Canopy and ductwork was to be a key interior design feature of the restaurant, it needed to be completely bespoke. Starting with all necessary standard features such as induction air supply, make-up air through perforated panels along the front of the canopy and baffle filters on the kitchen exhaust, the design was then enhanced to achieve the brief.
The top of the canopy would be viewable by diners in the open mezzanine area but it also needed to be accessible for cleaning and maintenance. The perfect solution was a dedicated support system complete with Chequer-plate flooring walkway.
The fire resisting ductwork requirement was satisfied by using non-coated, fire rated CASWELL FIRESAFE® product. This internationally renowned product is manufactured by Caswell under licence from our sister company FIRESAFE Fire Rated Ductwork® Limited. http://www.firesafeductwork.co.uk
