In South Africa our political leadership is sometimes referred to as the song and dance brigade. A well-known South African comedian jests that it is only in South Africa that people dance when they are angry - building from a gentle conversational disagreement, into a rowdy argument, and finally into a vociferous dance and chant that we call the toyi-toyi. Th is is just another social characteristic that makes South African society authentic - an exclamation of furious rage accompanied by the foxtrot. Perhaps there is an anger management lesson here on how to deal with conflict resolution and office squabbles.
Bosun recently launched a precast channel kerb to further expand its range of SABS-approved, dry-cast concrete kerbs. Bosun's state-of-the-art German block-making machines and moulds enable the company to produce a wide variety of concrete pavers and kerbs. Kerbing, in particular, can be produced much more effectively and accurately using these machines, rather than through the traditional wet-casting methods
The three articles from the CEO's desk in the June, July and August 2011 editions of Civil Engineering make for interesting and thought-provoking reading. In many senses they also make depressing reading in their insights into the current situation in the civil engineering industry. In spite of the guarded optimism of the CEO we are actually facing a potential disaster in the coming years. How can we as a developing country afford to have young, and not so young and experienced engineers, made redundant because government cannot get its "ducks in a row"? With 50 years of experience in the consulting industry in many parts of the world, which has given me great satisfaction, it saddens me that this experience is being denied to many young and enthusiastic new entrants.
The guest list for the special celebration dinner for the contractors involved with preparing stadiums and infrastructure for the 2010 World Cup clearly revealed that our construction industry, sixteen years after democracy, is still managed predominantly by white businesses and business people.
Situated in the Inanda, Ntuzuma and KwaMashu (INK) area, 17 km from the Durban City Centre, the Bridge City development aims to bridge the social divides of the past to create a dynamic, vibrant city precinct that celebrates diversity and sustainability. The INK area was identified as a critical development node due to the high levels of poverty. The precinct promises to be the retail, residential and investment destination of choice for approximately one million people living in the INK and Phoenix areas.
eThekwini Water and Sanitation (EWS) completed an asbestos cement (AC) pipe replacement project under the New Engineering Contract 3 (NEC3) where 1 600 km of ageing AC pipes were successfully decommissioned and replaced with modified polyvinyl chloride (mPVC) pipes over a three-year period from July 2007 to June 2010, at a cost of R1,9 billion.
Condition assessment of ageing pipelines is a continual challenge in South Africa and around the world. Owners of large diameter water and wastewater pipelines face particular difficulties due to several factors, including severe skills shortages, and financial, environmental, demand and access restrictions. While desktop studies can identify pipelines with a high likelihood and consequence of failure, actual condition assessment data has traditionally been difficult to collect, especially in pressurised pipeline systems. This information is particularly important when estimating the remaining useful life of a pipeline, or when considering repair or replacement programmes. A toolbox approach is required for the variety of pipeline materials and conditions encountered. Regardless of the technique used, collecting the information is critical to making informed decisions regarding any pipeline. Rather than embarking on conservative and expensive replacement projects, inspection programmes enable significant cost savings through targeted repairs and rehabilitation
The Department of Water Affairs (DWA) has embarked on a nationwide programme to develop water reconciliation strategies for all towns across the country. The initiative to develop a "Water Road Map" for South Africa at various scales was started by the Department in 2000, when the Water Situation Assessments for each major basin in South Africa was undertaken. These studies were followed by the Internal Strategic Perspectives for each Water Management Area in 2004.
The drought conditions of the past three years, in the dam catchment areas supplying the Nelson Mandela Bay Metropolitan area (NMBM), were severe. A series of interventions, initiated by the NMBM and the Department of Water Affairs (DWA), were started with the express intention of alleviating the drastic water shortage. A team of multidisciplinary consulting engineers and specialist experts was appointed to investigate, report and act on each of these options, from technical, budgetary and time requirement perspectives. The team was made up of the NMBM, the DWA, Aurecon (lead consultant), Africoast, Groundwater Africa, Uhambiso, Ndodana and Carifro.
In an article titled, Sewerage the next ESKOM (29 April 2010, SAPA), a Green Drop report from the Department of Water Affairs was quoted which stated that more than 75% of South Africa's sewage plants are not up to standard. In Business Day of 28 April 2010 it was reported that only 7% of wastewater treatment systems comply with international standards.
South Africans are vociferous about municipal service delivery and the condition of municipal assets, as is regularly and graphically depicted by the media. There clearly is a need for a more structured and organised asset management system. Municipal Managers, CFOs and Asset Managers are now in a situation where a holistic approach must be defined, adopted and implemented to ensure continuous sustainable service delivery
Contract administrators often find claims involving concurrent delay in the construction of municipal infrastructure difficult to resolve, given the circumstances of complexity of work, extensive interfacing between services and contractors, all taking place in a dynamic urban environment.
The accomplishment of Century City as a mixed-use development, ten kilometres from Cape Town's central business district, demonstrates that thriving urban spaces are those that achieve the optimal balance between aesthetic, functional and commercial interests.
Crete Colours (also known as C2) comprises a range of concrete treatment products developed and perfected in America, and available in South Africa, Canada and 33 other countries worldwide. The range (which includes hardening, sealing, polishing and colouring products) is lithium-based and utilises nanotechnology, resulting in a range of incredible benefits that are driving the transformation of the concrete flooring industry.
