This guide is intended to assist those responsible for procuring emergency food stores in selecting an appropriate system. It outlines the factors to be considered, most of which have been more fully discussed in Part 1, and provides a decision tree to help in making a choice. Manufacturers of structures are listed and their products described, under four categories.
A Warehouses B Frameless buildings C Framed structures with flexible cladding D Frameless flexible systems.
This guide assumes that the structures, or critical components of them, are imported; however, there will be times when structures can be locally manufactured, thereby probably reducing the procurement time.
Information on examples of five of the most important types of store is summarized in Table 6. From this it is clear that where speedy procurement and erection of a store is essential, tarpaulins (for bag stacks), tents and plastic-clad stores can be obtained rapidly by air and erected quickly. Because these stores are relatively light-weight and because they have simple foundations or ground anchors, they are also easy to relocate. Their drawbacks are that they are difficult to manage and vulnerable to theft because the canvas or plastic sheet can be easily cut open; hence they require security fences and watchmen. They are also vulnerable to water (both ground moisture and flooding) in wet weather, and dunnage or pallets should be regarded as essential. They are easily damaged by wind and precautions against this are needed.
At railheads, ports or where an emergency is prolonged, more permanent storage with concrete damp-proofed floors is appropriate. These stores (whether warehouses or frameless buildings) are easier to manage and more secure. However, they are slow to procure and erect and not easy to relocate. Construction often requires expatriate supervision.
Costs of emergency storage are considered in two ways. 'Capital' costs for imported stores include packing, freight, insurance, customs' clearance and erection costs as well as the ex-works price of the structure. These 'once and for all' costs can be spread over the life of the structure and with the appropriate addition for interest are then called 'annual' costs. If warehouses are utilized for their whole working life, their annual costs (see Table 6) are much lower than tarpaulin annual costs, for example. But for a short emergency of, say, one year's duration this is not so. The 'break-even' point will depend on factors unique to each individual emergency. Where a warehouse has a turnover of relief food once every two months and the emergency lasts for 4-6 years, then depending on management, the price of relief food, the losses saved, etc., the annual costs for warehouse storage can be lower than tarpaulin storage. (For more details of costs see Appendices 9 and 10).
Table 6: Procurement period, capital
and annual costs per tonne for different
structures
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.
In Section Storage operations it is shown that temporary stores are preferable where speed is essential, but more permanent stores are easier to manage. From Section Storage costs a guide to 1987 costs is available and in Section What size of structure to order a simple method of calculating store size is suggested. The decision tree (see Figure 1, p. 22) allows all these factors to be taken into account and in addition takes account of the following priorities in order of importance:
A: Is the warning of the emergency early or late?
If the warning is early, use the left-hand branch where more permanent structures, either local or imported, are feasible. If the warning is late, more temporary storage systems must be employed. However, the food store only has a function once a flow of relief food supplies is established, and the assessment of urgency should take into account the time needed to achieve this.
B: Is funding ample or scarce?
Many relief agencies can command appropriate funds but this priority is included to help keep capital costs in mind. For example, plastic-clad stores are about £56 per tonne stored while tarpaulins are £11 and therefore can, in the short term, afford five times as much protection for the same expenditure.
C: Is site management good or poor?
Branches stemming from poor management include the decision that imported supervision will be needed for store erection. Branches stemming from good management embrace difficult-to-manage systems like cover and plinth (CAP) storage and air-supported warehouses.
D: Is site transport and labour availability good or poor?
Branches stemming from poor transport/labour include facilities to speed up the turn-round of lorries. Hence, for example, drive-through stores or stores with canopies are recommended.
In the majority of food-relief emergencies warnings are late but there is ample funding; on-site management is usually good but in our experience transport is often poor. In this case the locally made plastic-covered wooden frame structure is ideal. If such structures are not easily available locally, imported plastic-clad structures should be used. Whatever the type of preferred store, selected by means of Figure 1 or otherwise, it is recommended very strongly that IN EVERY EMERGENCY STORAGE
SITUATION AS AN INSURANCE AGAINST DELAYS AND AS A FIRST-AID MEASURE, TARPAULINS SHOULD BE PURCHASED AND DESPATCHED BY AIR TO COVER THE INITIAL STORAGE REQUIREMENT. THE PROCUREMENT OF OTHER STRUCTURES FOR THE TOTAL REQUIREMENT CAN THEN PROCEED NORMALLY.
In dry weather additional storage can be obtained with temporary bag stacks (covered with tarpaulins). This is particularly useful at intermediate storage centres between port and distribution points (Friendship, 1987).

can advise names of additional manufacturers.
Pallets are costly to send by sea or air freight and local assembly of pre-cut components is a possible alternative.
Tendering
It is the purchaser's responsibility when preparing tender forms to request the vendor to answer the following:
(i) What is the structure design wind speed?
(ii) What form
of foundation is supplied for sandy soils? Does this affect (i)?
(iii) Is the
structure designed for tropical exposure, i.e. are all parts, including ropes,
UV-resistant?
(v) Is erection without a supervisor practical? Have visual
instructions and local language manuals been printed and are 6 copies supplied?
When evaluating tenders, the purchaser must check the data on
designed wind loading against recorded local gust speeds, to determine that the
structure is safe.
Where possible, purchasers should ask for a demonstration
to judge for themselves ease of erection/relocatability.
Site selection
A level site protected from flooding with good access is vital. If possible the site should be in an area without strong winds or it should be protected from wind. ALWAYS ASK LOCAL PEOPLE ABOUT POTENTIALLY WINDY SITES.
Installation
The purchaser should ensure
(i) That the supplier's engineer/supervisor will be available
for erection overseas.
(ii) That erection and loading only take place in dry
calm weather.
(iii) That the relief food is inspected to prevent wet sacks
being loaded.
and should take these steps prior to erection of stores:
(i) Clear vegetation from site.
(ii) Mark out store bases at
least 6 m apart to allow for lorry access.
(iii) Clear the base of stones and
sharp objects which can damage tarpaulins, etc.
Suppliers should provide supervision and training in erecting the structures as part of the contract, even if charged separately. Users should recruit a reliable foreman and understudy at each site to take full advantage of this service. With the foremen and his understudy as the nucleus, a trained erection team can be formed to ensure the success of future operations.
