Project Location: Centurion, Gauteng Province
Project Value: R1,2m
Services: Planning, design, tender adjudication & construction supervision
Project Period: January 1998 to July 1998

Rantesig is a suburb located within the municipal jurisdiction of the former Centurion Town Council. Infraburo (Pty) Ltd was appointed in January 1998 by the Centurion Town Council for the design and construction supervision of the first phase of a bulk supply pipeline to Rantesig. The work to be carried out included the construction of a 400 mm diameter steel pipeline with an overall length of 5 000 m through Mnandi AH and Mnandi AH Extension 1, utilising pipes and valves already acquired by the Town Council. Pipes were already delivered and stacked on site in the vicinity of the proposed pipeline route.
Pipes used for the construction of the pipeline were Sintakote pipes with either Sintajoints or flanged joints as specified. Fittings and specials, such as bends and tees, were manufactured on site using the same pipes. The work further included the installation of isolating, air release, and scour valves and associated pipework and valve chambers, the crossing of internal roads in Mnandi AH as well as the Provincial Road P102-1, subsequent repair of tarred surfaces, and the associated accommodation of traffic. Crossing of the Provincial Road P102-1 was done by means of pipe jacking.

The work also included the connection of the new pipeline to the existing bulk supply system, as well as pressure testing, sterilising, scouring and commissioning of the completed pipeline.

The pipeline had to be installed along the back or side boundaries of a number of existing properties as result of a lack of space to accommodate the pipeline within the street reserve. The project required intensive liasion with each and every owner whose property was affected by the pipline route. This was achieved through means of regular contact , correspondence and interest group meetings. Where possible, the route was revised so as to minimise the impact on affected properties.

Labour Intensive Construction methods were implemented where possible and construction activities such as the placement of pipe bedding, backfilling and finishing of trenches, small concrete works and dayworks were conducted by locally employed people.
The project was completed within the set time and budget allocations as laid down by the Council.
