B&M Bargains - Warehouse Design

Following on from their continuing growth B&M were looking to open a Southern DC to support their Southern Stores. A site had been identified and LPC were initially retained to carry out a validation of the proposals for the site prior to submission of planning applications by the developer.  The high level brief was to validate the requirement for a 1 million square foot warehouse with consideration to automation.

LPC reviewed the data requirements from the existing DCs which were then extrapolated for the expected Southern dependency and looked at the options for the proposed 1millon square foot facility.

Due to the business philosophy stock per SKU could vary from 1 pallet to many pallets with a large number in the latter bracket and with high average stock per SKU. Options considered therefore varied from basic conventional storage, wide aisle adjustable pallet racking to automated high bay with shuttle storage and utilising pick tunnels for the fastest moving SKUs.

During the course of reviewing the options it became clear that an automated option was not going to be financially viable with the building and site sizes that were planned.

The focus then changed from a validation exercise to providing a concept design for a more detailed solution to allow for the developers to progress with the planning approval process and provide detailed development costs The concept options investigated  were  standard wide aisle APR which could be augmented by some carton live storage to cater for the slower moving SKUs  with less depth of stock and also for  the temperature controlled chambers.  Also investigated were deep storage types such as push back, drive in, double deep, block stack and shuttle racking. The Shuttle or mole type storage was recommended because it provides:

  • The ability to be operated with VNA trucks allowing higher racking and more capacity (Diagram shows reach trucks)
  • Allows semi – automated and automated operation now and in the future of VNA Combo trucks
  • Pick tunnels with live storage feeding the pick faces for more controllable replenishment
  • Flexibility as to how the storage is used to support the separate SKU pick faces
  • Safety with no mixing of large VNA or reach trucks with pedestrian picking

The remainder of the facility was conceptualised around the storage solution and vehicle requirements and included a one way route for HGVs around the site. The ancillary facilities included:

  • Gatehouse
  • Derv Island and surface mounted tanks
  • Vehicle wash
  • Vehicle maintenance unit
  • Vehicle and trailer parking
  • Resource recovery unit (within main building)
  • Battery charging – (2 locations Temperature Controlled and ambient) 
  • MHE workshop area
  • Canteen
  • Locker and ablution areas
  • Main Office and Operational offices
  • Car parks
