The Con-Cottage Building System is a labour-intensive building system which can maximise local participation and has been designed to provide protection from the elements during construction by first erecting temporary external wall formwork and supporting the roof construction on the formwork.
The building system consists of:
- cast in-situ strip foundations with a strip of weldmesh reinforcement cast into the foundation to anchor the wall reinforcement;
- temporary mild steel formwork to the external face of external walls, lined internally with weld mesh reinforcement, wire-tied to the foundation reinforcement. The corners of openings and internal wall junctions have additional weldmesh reinforcement;
- timber rafters which are temporarily supported by the formwork and anchored with galvanised hoop-iron straps to the reinforcement. Profiled galvanised roof sheeting is fixed to the rafters, forming a sheltered working environment;
- external walls of micro-concrete, applied in two layers to a minimum thickness of 50 mm;
- internal walls constructed in the same way as external walls;
- floors are conventional screeded or steel-floated concrete surface beds.
The dwelling can be upgraded by adding rooms.
This Mantag certificate covers the use of the Con-Cottage Building System in selected areas in all climatic zones of Southern Africa for the erection of simple, single storey buildings for the following uses:
- detached houses and ancillary free-standing buildings
- primary health-care facilities, to a maximum floor area of 300 m2
- non-residential school structures.
Mantag certificates are a distinct type of Agrément certificate, based on acceptable safety and health criteria for houses and related outbuildings, non-residential schools and primary health-care centres in areas where the local authority is of the opinion that the type of construction is appropriate, given that in these areas it is of paramount importance that buildings be erected at the lowest possible cost.
If the conditions of the Mantag certificate are complied with, Agrément South Africa is of the opinion that the Con-Cottage Building System will be fit-for-purpose, and can therefore be regarded as complying with the functional requirements related to safety and health contained in the National Building Regulations. In general, however,
Mantag criteria permit a lesser level of performance than would be expected from buildings erected in accordance with the deemed-to-satisfy rules contained in SABS 0400-1990, The application of the National Building Regulations.
