In the fast lane
The Nelson Mandela Municipality has appointed SBA to
provide consultancy services for the rehabilitation of the
William Moffet Expressway, a dual lane highway in Port
Elizabeth that can no longer efficiently cope with the
increased volume of traffic.
“
Joining
hands with
Dedini
T
he number of vehicles using the William Moffet Expressway, which
connects Cape Road and Buffelsfontein Road, has increased over the
last 20 years and although the road has been upgraded to two lanes in
each direction, it has now reached its capacity and desperately needs an
upgrade,” says Greg Cummings, director of SBA. “Recent floods in PE have
also resulted in closure of many alternative routes, which has increased
usage of the William Moffet, resulting in significant traffic congestion.”
SBA has prepared a detailed assessment report which highlights the limited
structural life of the existing pavement in many parts of the roadway. Many
new large commercial sites are being developed along this expressway,
it is therefore important that the master plan for new roadworks fits in with
the long term spatial development plan.
The master plan proposes three lanes in each direction and deals with
land issues, as well as future lane configuration. Phasing has also been
recommended, with Phase 1 expected to commence during 2007.
At the signing ceremony in Brazil recently were (from left) Bill Yeo, of
Bosch Projects, Jose Davos, vice president of the sugar and alcohol
division for Denini, Mike Gibbon, managing director Bosch Projects, Ivan
Voigt and Martin Welch, Bosch Projects.
Bosch Projects and Dedini Industries de Base have recently
signed a memorandum of understanding in terms of which
Dedini will exclusively use the patented Bosch Projects
chainless diffuser technology in Brazil.
D
edini is the largest supplier of equipment to the Brazilian sugar
and ethanol industry, with a 55% market share and projected
revenues of US $ 964 million in 2006.
Brazil, the world’s leading sugar producer, manufactures about 26
million tons of sugar per annum, with the lowest costs of production
globally. The industry is expected to grow some 47% in the next six
years, with 73 proposed new factories by 2011. By 2021, Brazil expects
to process one billion tons of cane annually.
The Bosch Projects chainless diffuser replaces many high value items
in a conventional diffuser. This means systems can be constructed at
substantially lower costs and can be easily expanded in capacity. The
chainless diffuser can be widened, almost without limit, by simply
adding moving floor sections.

Save the water in Soweto
Johannesburg Water has appointed the Londa Madi
Consortium to implement ‘Operation Gcin’amanzi’
(save the water) within Superblock 12, situated in Protea
Glen, Soweto.
J
ohannesburg Water adopted a ‘design and build’ approach to
address water loss problems in Soweto, which includes the upgrading
and rehabilitation of the existing water reticulation system in the area.
The Londa Madi Consortium, which was appointed to design, construct
and manage this project, comprises consulting engineers, SBA and
contractors, Ilima Projects and MIS Pipelines. Nemai Consulting are subconsultants who assist with the identification, screening and training of
local SMME contractors.
Technical intervention requires that the complete network, comprising
existing secondary and tertiary reticulation, be surveyed with regard to
condition and leaks.
Each Superblock is to be divided into discrete blocks, not exceeding
5 000 sites. Block discretion of the reticulation system is designed to
create smaller manageable water loss control zones. Post intervention
consumption monitoring will be carried out on each block.
SBA has completed a comprehensive hydraulic design and compilation
of the ‘block design plan’ which includes pipework, bulk meters, pressure
reducing valves, isolating valves, hydrants, saddles and other fittings.
Pre-intervention property to property plumbing surveys have also been
conducted in order to establish the condition of on-site plumbing.
Once the ‘block design plan’, which encompasses comprehensive
scheduling and costing of the upgrading and rehabilitation requirements
is approved by Johannesburg Water, construction work will begin. This
will include the installation of secondary and tertiary reticulation where
required, secondary mains leak detection, bulk meter installation, domestic
meter installation, on-property plumbing repair and retrofitting and
decommissioning of current secondary midblock mains where necessary.
This R19.7-million contract commenced in June 2006 and is scheduled
for completion by July 2007.
