Client: Hibiscus Coast Municipality

Project: Umtamvuma / Port Edward Transitional Local Council Upgrading of Roads and Stormwater Drainage

Description: Approximately 6km of existing asphalt surfaced roads were reconstructed and resurfaced. The work also included the upgrading and new construction of the stormwater drainage in the form of concrete pipe culverts, kerb and channelling, subsoils and mitre drains.

Road Works

  • Subbase
    The insitu material was scarified to a depth of150mm, reshaped and compacted to 95% Mod AASHTO density to form the subbase. Section in which poor material was encountered was undercut and replaced with gravel material from the borrowpit.
  • Base
    The base was constructed using a 150mm thick layer of gravel material stabilized with 3% anionic bituminous emulsion (retread emulsion) compacted to 97% Mod AASHTO density.
  • Surfacing
    The wearing course consisted of a double seal chip and spray, comprising of a 13.2mm chip bottom layer and a 6.7mm chip top layer.
Drainage Works
  • Surface run-off from the roads was controlled and channelled by concrete kerb and channelling. Where kerb and channel was not provided, the verges were trimmed back at the existing grade of the road, into existing open drains.
  • Various concrete, earth and stone-pitched chutes, headwall Is, access pipe crossings and concrete stormwater pipe crossings were constructed where necessary to assist with drainage and protection of the roads.
  • Subsoil drains were constructed where the subsurface water was high.

Project: Ethekwini Municipality’s Zibambele Programme

Description: Introduction

The Municipality’s Zibambele Programme which has been running for almost a year is a POVERTY ALLEVIATION PROGRAMME focused on empowering households, especially woman headed households. It was adapted from the KwaZulu-Natal Department of Transport’s programme which focuses on rural areas. The Zibambele contractors carry out LOW INTENSITY ROUTINE MAINTEANANCE OF URBAN ROAD. The contracts are aimed at stabilizing destitute families and are targeted at the poorest of the poor.

Zibambele work is labour intensive. The contractors work only two days a week, allowing them to deploy their labour to other activities. The length of road to be maintained depends on the terrain and Contracts are awarded for a year which can be renewed.

How It Works

Women headed households are targeted because they make up the majority of the poorest households. New sustainable work opportunities are created at the lowest levels of the market place and training includes technical skills on the correct way to maintain roads as well as social development and life skills components.

Support services to the Zibambele households include assisting them to obtain identity documents, open bank accounts, organize themselves collectively into credit unions and assisting people to invest savings in other productive activities.

Tools and Equipment

All tools necessary to carry out the work are provided by the Municipality. Tools are supplied by local suppliers. Their condition is checked every month and replacements are issued when necessary

Measuring The Success Of The Programme

The success of the Zibambele Programme will be measured against the number of savings clubs it has managed to create, the number of people who, through the programme have acquired identity documents and bank accounts for the first time and the rideability and accessibility of the roads maintained through the programme.

The Zibambele Programme Is a Building Block For Other Public Works Programmes, It Targets:

  • The Contractor – Breaks the poverty cycle and become functioning members of society.
  • The Overseer – Provides supervisory and technical skills for other municipal initiatives.
  • The Co-ordinator (trainee technician)- Creates social and moral awareness through community service besides obvious technical training.

The bridge is to consist of five 10,6m spans made up of precast concrete beams and a reinforced concrete deck. Four reinforced concrete piers and two reinforced concrete abutments with associated concrete wingwalls have also been designed and will be constructed in the 2005/2006 financilal year. The construction of the Bluebank Bridge is currently estimated to cost R 3,500,000.00 and is to be constructed by a Stage 4, Vukuzakhe Contractor.
