CONSTRUCTION METHODS
1. CONVENTIONAL METHOD
Using strip foundations, slabs, brickwork, timber trusses, roof sneeting or tiles, piaster externally, bag wash or piaster internally. Standard components such as windows, doors, sanitary fittings, etc., would be used depending on sophistication of housing unit.
Advantages:
Materials generally readily available Technology not sophisticated
Some building elements (e.g. bricks or blocks) can be made by the intended occupier or community. This would engender ''entrepreneurial" spirit and create employment within the -community.
' Finished structures can be extended easily at a later date.
Disadvantages: :
Slow rate of construction
Relatively high cost of construction
2. TRADITIONAL METHOD:
Using "wattle & daub" frame work plastered with clay, thatched roof, rnud/dung floor, painted or bag
washed internally and externally. Standard components such as windows, doors, etc., would be
used depending on sophistication of the unit. This method of construction would have limited use,
and should be restricted to construction of traditional kitchens and hozi's at homesteads.
Advantages:
Technology not sophisticated, and methods well known in rural communities.
Materials generally readily available
Very low cost of construction
Easily replaced if necessary
Disadvantages:
Unsuitable for residential use when viewed in the context of the aims and objectives of the
Ministry's housing policy
Relatively short life-span for the building
3. ALTERNATIVE TECHNOLOGIES:
Such as the "Frame Tech" System. Utilises steel frame construction on raft foundations (though
conventional strip foundations and slabs are usable). External walls piasiered and painted: internal
walls gypsum beards, rendered and painted.
Advantages:
Light-weight structure that can be erected more speedily than conventional methods
Manufacturers claim that method is cheaper than conventional methods
Materiais generally readily available but main structural components are not avaiiacie except from
the manufacturer
Disadvantages:
Sophisticated technology requiring training to enable builders to construct
Finished structures cannot be extended at a later dare as easily as building constructed by
conventional methods
4 .OTHER TECHNOLOGIES
Additional facilities coulc be provided to each structure dependant on need and cost. Such facilities wouid include soiar charged batteries for limited lignting; soiar water heaters.
