|Structures Suitable for Emergency Storage in Tropical Countries (NRI)|
|Part II: Users' guide to relief foot! stores|
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.
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.
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.
