The credit crunch and mezzanine floors Mezzanine floors and planning permission

Mezzanine floors in food production

December 12, 2010

The mesmerising ballet of ‘Doughnut theatre’ – the continuous doughnut production line now seen at retail centres around the UK relies at its heart upon a mezzanine floor designed, manufactured and installed by Llonsson Ltd in Surrey.

When a US doughnut manufacturer first came to the UK, a central warehouse and production facility was required where new staff could be trained on their specialised doughnut manufacturing equipment, production of doughnuts could be made for their smaller outlets and stock of their special flour and mixes could be kept.

Llonsson Ltd was asked to design and provide a mezzanine floor for the new facility. The client had a number of special requirements, in that a specific clear height under the mezzanine flooring was required for the equipment, access was required from existing offices onto the new mezzanine floor, service penetrations were required for air handling equipment, no food traps were acceptable within the doughnut production area, all ceilings would be continuous, and therefore service access to cabling was required from above the mezzanine.

As the existing office floor height conflicted with the mezzanine floor height necessary to fit the machinery below, an underslung landing was provided to accommodate steps between the two levels.

Service penetration positions were agreed and trimmer beams and cleats were incorporated in Llonsson’s design to suit.

To avoid food traps, Llonsson recommended the use of two base plate types, sub surface recessed plate (SSRP)  for locations of columns within the production area and concealed construction partition plates (CCPP) where columns could be integrated within partitions, and also that the walls use a jumbo stud construction so that columns could be lost within the depth of the wall itself, leaving the internal and external surfaces flush.

The requirement to access services from above was achieved using Llonsson’s CaviT top access service duct design, enabling services to be reconfigured without needing access through the food production area ceiling.

Following preparation of manufacturing drawings, Llonsson liaised with the client’s building contractor, setting out the column centreline positions on site and marking out the extents of the necessary pockets to be cut into the concrete slab so that this could be undertaken at the same time as cutting of floor drainage channels. Llonsson then coordinated with the building contractor to ensure that excavations had been made good and fork truck access was available for installation of the mezzanine flooring.

The advance planning and coordination finally paid off, with another of Llonsson’s mezzanine floors expertly installed on time and on budget whilst satisfying all of the clients performance requirements.

The mezzanine flooring project was duly followed by an order for the design, supply and installation of the warehouse racking to complete the project and ensure that original glazed ring doughnuts are now available to us all!
