### What size of structure to order

The following questionnaire and worked example in Table7 is based on one transit store but could be applied to a whole emergency distribution system of port store, regional stores and district stores.

Table 7: Store size calculations

When the actual required floor area, B, has been calculated, the warehouse dimensions can be determined. For economy these should be chosen from the supplier's standard range. Thus, if a 15 m span is standard, length required is 562.5 /15 = 37.5 m. The nearest multiple of the standard bay length may then be selected, e.g. 39 m for 3 m bays.

For tarpaulin quantities it is economical to order standard sizes of sheet, e.g. 7.5 x 10 m. Using one as the ground sheet, allowing 1 m margin all round, this will support a stack of 5.5 m x 8 m x 2 m high as before.

 Then stack volume = 88 m³ Stack weight (calculated as rice) =88 /1.5 tonnes =59 tonnes.

Two further tarpaulins 7.5 x 10 m each will easily cover the stack allowing for 1m overlaps. Hence a total of three will be required for a 2 m high stack of 59 tonnes.
