Since the 1994 electionS, municipalities have been focusing
on the delivery of basic services, that is, roads, drainage,
water, sanitation, electricity and health services. the Development
Bank of Southern Africa (DBSA), the Department of Water Affairs
and Forestry (DWAF), the Department of Provincial and local
Government (DPlG) and the infrastructure Finance corporation
(incA) alone between 1994 and 2004 funded at least R37 billion
investment in engineering infrastructure new works, upgrading and
rehabilitation, the bulk of it to water services. in addition, a signifi-
cant proportion of the R29, 5 billion spent by the Department ..

issues in the spotlight
theRe ARe 1, 2 Billion PeoPle in the world today without
access to safe drinking water, while 2, 6 billion people do not
have access to proper sanitation. in addition, 50 % of solid wastes
remain uncollected. the development of appropriate technical
options and implementation methods to address these concerns
were discussed earlier this year at the third international
conference on ecological Sanitation (ecoSan) in Durban and
refocused attention on not only all aspects of ecological sanitation,
but also how sustainable development approaches can be
used to achieve the ..

PRioR to the 2005 Un World Summit,
the Stockholm environment institute (Sei)
was tasked by the government of Sweden
to shed some light on the question of
how the Millennium Development Goals
(MDGs) could be met using sustainable
the objective was to clarify the major
environmental investments required to
attain the MDGs and to identify sustainable
solutions where synergies between
the environment and development can be
achieved for more rapid MDG achievement
and to secure long-term sustainability,
also beyond 2015.
the report the Sei team produced highlights
the importance of the environment ..

the neeD FoR capacity building within
municipalities is clearly becoming a major
issue in South Africa and the lack of expertise
in many parts of the country has been
highlighted as a critical factor that will hinder
one of the aspects where most municipalities
lack capacity is in the maintenance
of automatic control valves in water reticulation
systems. control valves are an essential
component of most water reticulation systems
and include amongst others: pressure
reducing valves, pressure relief valves and
reservoir level control valves.

A FeW MonthS AGo, the rural town of Uniondale was
completely different from the one that we know today. this
fundamental change is largely due to the upgrade of various
main roads that began in earnest in november 2004. this
much-needed venture has since been completed with a total
project cost of ?R2, 2 million.
the project, which was identified by eden District
Municipality, was aimed at uplifting the low income area of
lyonville and entailed the upgrade of Berkley Street as well as
a section of long Street. the road was upgraded from ..

projects is measured by their out-turn performance
compared with the forecasts used
to justify them, then performance is seldom
good. Much attention has focused on implementing
projects to time and budget.
Poor construction and cost performance
has increasingly been targeted and there
has been a step-change in performance
under some procurement regimes - such
that this aspect of performance is now often
good. the major problem today is with
operations, where performance is still often
poor - a fact that arouses surprisingly little
interest despite its obvious importance.

The leading dimensions of the Boeing 747 aircraft are given in the paper, as well as the parameters and other considerations which influenced the design and construction of the hangar. Mention is made of special features such as the hangar floor, the crane system, fire protection and the internal- buildings. Site assembly and erection of the steelwork is descriptionbed.
A method to determine the strength of the cubic pressure of concrete after 28 days at an age of 24 hours, is discussed. Extensive tests proved that engineers and building contractors can benefit by the use of this method.
This paper descriptionbes the data obtained from the instruments placed in the Bridle Drift embankment to measure settlements and pore pressures. Internal settlement data have made possible the evaluation of the compressibility of the dolerite rockfill and comparisons are made with similar data from several overseas dams. A longitudinal crest crack resulting from differential settlement between the upstream shell and the remainder of the fill is discussed. Piezometer data obtained in the decomposed shale core both during and after construction are evaluated with reference to similar data from two other South African dams.
The original paper descriptionbed the general planning criteria for Johannesburg, listed the client's particular requirements, descriptionbed the structure and the development of the design, and covered certain particular designed construction aspects in detail.
