Twinstore and twin tanks for Tesco

Besides its compactness, the ability of Tubosider’s Twinstore system to fit within challenging areas has again proved its worth at the new 80,000 sq ft Tesco superstore in Corby.

The development is on a brown field site within the St James Industrial Estate, which proved to be crossed by a number of existing drainage systems, both foul and surface, plus sections of an 1800mm concrete culvert.

As contractors for the £15 million project on behalf of Mulberry Developments, Barr Construction chose to install a Twinstore system over the crates originally planned. As Tubosider’s proposal showed, linking two Twinstore tanks could fit around the drains and also provide a more commercially attractive alternative.

“A successful fit within the defined zone was critical, with almost 4300 cubic metres of stormwater attenuation required to serve the new store and its related facilities. Also at issue were the strict requirements of the Environment Agency,”says Barr’s unit manager Mike Henderson.

Tubosider’s design team solved the overall challenge with two 1800mm diameter tanks linked by a 20 meter pipe bypassing the area of the drains and an increased 1500mm of cover.

With the new store due to open its doors later in 2012, the 30-week construction schedule will also see Barr create a goods and service yard with access from St Luke’s Road as well as car parking for 733 vehicles.

Road improvements at the Elizabeth Street and Lloyds Road roundabouts and the Station Road Oakley junction will also be carried out. The initial construction of the shell and core should be completed by late autumn 2012, when the building will be handed over for a Tesco fit-out.

The finished store will create over 200 jobs and is expected to include Tesco’s extensive grocery offer as well as a hot counter, cafe, in-store pharmacy and non-food range.
