TRANSPORTATION PLANNING AND ROADS - Xai-Xai IDP

Labour intensive construction

Construction must be planned for high labour content in order to maximise the opportunities for the local community. This includes training schemes, assistance in obtaining finance and equipment.

Specific opportunities for labour intensive construction are found in the construction of local roads where the variability in material preparation is less critical, the construction of side drains and paving. A patented system such as Hyson Cells can be used for side drains: this system provides a preformed cell structure that is filed with a sand-cement mix, resulting in a segmental slab with controlled cracking.

Potential Demonstration projects emanating from roads The following projects can be developed into demonstration projects:

Local roads in Xai-Xai Beach or Praia Velha: Manufacture of paving bricks from local material and cement; Pre-forming of sub-grade by construction equipment; Transport of selected and base course material from borrow pits by local contractors; Forming, mixing and compaction of layers by local labour; Paving and drainage by local contractors.

Parking area and public transport facilities at Halley’s Hotel: Manufacture of paving bricks from local material and cement; Pre-forming of sub-grade by construction equipment; Transport of selected and base course material from borrow pits by local contractors; Forming, mixing and compaction of layers by local labour; Paving and drainage by local contractors.

Promenade: Manufacture of coloured and textured paving bricks from local material and cement; Paving by local contractors.

4.3.3 Maintenance

The design and construction of all the roads must be done with a predetermined maintenance policy in mind to ensure that the correct trade off between initial construction cost and maintenance is made over the life cycle of the road. If no maintenance is planned, and the road is to maintain serviceability, a stronger initial construction is needed.
