Ed’s Diner is part of the continued development of the major food retailer SSP’s food outlets across transport hubs such as airports and railways throughout the country, as part of this CJDP are employed as MEP consultants.The new Ed’s Diner is located within the vaulted steel structure of London Liverpool Street station mezzanine level, and covers an area of over 1800 square feet. The unit is glazed on all four elevations and roof which provided a unique challenge for the M&E services; not only to blend them with the Client’s overall concept, but also to ensure they were integrated with the structure itself – taking into consideration the specific structural constraints and visual impact.
In the restaurant area both the Mechanical and Electrical services were exposed, with ceiling hung chilled water fan coil units and small power, lighting, data, fire alarm, security services and refrigeration pipework all housed in a new exposed containment structure.
A new energy efficient LED lighting system was installed, including spotlights and downlights supplied by Hacel Lighting. The new fire alarm system was required to link to the overall Network Rail system and was designed and installed to comply with L2 building regulations and Section 12 of the Fire Precaution Act 1971 requirements.
Due to site constraints to provide sufficient extract & supply air for the new commercial kitchen installation, a highly efficient recirculation unit was used to filter extracted air and feed it back to the kitchen, which in turn enabled us to reuse the existing single duct to atmosphere for fresh air supply, dramatically reducing cost and time for the ventilation installation. Because of the site location, condensers for the walk-in fridge/freezer units could not be mounted externally so a bespoke solution was designed. The condensers were installed in the restaurant’s store room complete with a dedicated chilled water fan coil unit to maintain working temperatures, this was backed up with a secondary extract system so in the event of a failure with the chilled water system the condensers and associated fridge/freezer units would remain operational, thus allowing Ed’s to provide an uninterrupted service.
