Roger Bullivant Limited (RB) adopted the use of three electrically-powered piling rigs to deliver the piled solution for the phase two extended mezzanine floor.

• Before work could commence the floor slab was core drilled and sawn at each pile cap position. Arisings were lifted and mechanically removed.
• The 24 hour distribution centre operation had to continue while all works were carried out. Sound-proofed fencing was erected to lessen the noise and distraction that the operation could cause to the warehouse staff.
• 130 no. 220mm bottom driven steel cased piles were driven to an average depth of 11 metres to carry safe working loads of 250kN. All piles had to be pre-augered to a depth of 6 metres due to the compacted fill material.
• 35 no. reinforced concrete caps of varying sizes up to 1500mm sq were installed up to 600mm deep to finish flush with the existing floor slab.

• On completion, the main contractor installed holding-down bolts into the pile caps which provide the anchors for the columns which then subsequently
  support the mezzanine floor.
• Lutterworth IDC is already one of the most complex depots in Asda’s logistics services network operating an automated goods-to-man materials handling solution on a massive scale.
• The Autostore system provides the highest possible rate of space optimisation teamed with extremely dense storage, as robots on the top of the mezzanine automatically store and retrieve goods with minimum space requirements. Compared with traditional automated solutions, AutoStore allows far greater capacity and storage density, with up to 60% more goods stored in the same space as a conventional warehouse.
