It’s not uncommon for delegates at our workshops and seminars to ask us if Mal Walker can share his ‘rules of thumb’ on warehouse design. Therefore, we thought we’d put them here in an article, so anyone can refer to them when necessary. We’ve also added a checklist of things to consider during the early stages of warehouse design.
Warehouse Design Rules of Thumb
- Ideal Land to Building ratio in lineal metres, 1.7:1–2:1
- Building aspect ratio, 1.7:1 – 2:1
- Ideal Warehouse Height at Springing Line 9.5-10.5 metres
- Pallet per Sq metre ratio 1 – 1.2 (with conventional storage racking)
- Truck turning space 30-40 metres
- Approx 20 to 25% of warehouse floor should be left for non storage operations e.g. receiving, dispatching staging
Important Planning Points
- Always plan for driver-side reversing
- Do not compromise aisle space for the sake of a few extra storage bays
- Avoid funnels and bottlenecks
Checklist of Warehouse Design Considerations
- Requirements and specifications for loading docks
- MHE battery charging/changing stations (location and provision for ventilation)
- Building support columns should be spaced/located in a way that allows for optimal layout of storage media and aisles
- Number of warehouse doors/loading and unloading bays
- Location of offices and other non-storage space (canteen, restrooms, other)
- Ensure lighting will be adequate and ideally, environmentally friendly (LED, induction?), and low maintenance
- Minimisation of obstacles or areas creating bottlenecks in warehouse flow
- Minimisation of travel-distances within the warehouse
- Fire prevention and firefighting equipment
- Adequate drainage should be designed into the warehouse site
- Low-maintenance warehouse roof design
- Heating, climate control, and insulation
- Radio frequency, LAN/WAN, or other communication/data-transfer infrastructure
- Storage areas for empty pallets
- Waste disposal solutions
- Security concerns, such as car-parking, checkpoints, location of cameras
- Future plans for automation, expansion and/or a change in storage requirements
