A great deal is expected of the construction industry and this study will stimulate reflections by participants on their role and performance. Leadership and collaboration are needed to enhance the capability and focus of all who engage in the delivery process- a focus to grow, transform and nurture the national asset base of the construction industry. The study highlights areas of progress and provides insight on the significant challenges to the construction industry growth and creation of infrastructure, challenges that are closely linked to the need for raised levels of performance and empowerment. Construction accounts for about I 0 per cent of the world economy and approximately 70 per cent of construction investment is accounted for in the USA, Western Europe and Japan. The continent of Africa accounts for about one per cent. Per capita investment in construction in the developed world is approximately $2500 per annum compared to $46 per annum in Africa. Embodied in the policies and legislations is a fundamental recognition that a developing society inherited a construction sector that supports a strategically developed industry with world-class capability and an established material manufacturing sector. The post-1994 expansion of South African engineering and construction services into global markets is testament to this inherent capability and the potential of the industry, and was enabled by the country's passage to democracy. In parallel with policy and institutional reform, a range of early practical initiatives were introduced by government to direct the process of change. In this context, growth needs to be coupled with sustainable employment, empowerment and investment in human capital as a pre-requisite for improved industry performance and competitiveness. The policy framework also addresses the role and potential impact of government as facilitator, regulator and major client to the industry. These included the implementation of preferential procurement to stimulate access to the market by historically disadvantaged enterprises, and measures to address supply-side constraints such as access to entrepreneurial training, finance, and credit. The Black Economic Empowerment is defined as empowerment of a broad-based process, and adopts a scorecard approach covering ownership, management, employment equity, skills development, procurement, corporate social investment, as well as investment and enterprise formation. By meeting any, or a combination of these objectives, every company has the potential to promote empowerment (SA Construction Industry Report, 2004 ). The main objective is to create new business ventures which play a significant role in economic growth. For this reason, it makes sense to explore correlations between black economic empowerment activities and lagged indicators of procurement policies and procedures. Some of the findings are: •Lack of consistency in the application of preferential procurement policies • Ambiguous regulations • Clients' planning shortcomings • Inadequate budget • Capacity constraints The biggest concern is the lack of core skills among emerging contractors, that is, financial literacy, record-keeping and marketing Although there are excellent examples of financing initiatives in South Africa (SA), there are only a small number of financial institutions in SA that have low default rates on small business loans. / (MBA) North-West University, Mafikeng Campus, 2006

The study revolves around factors influencing the perceptions of service delivery by local municipalities in the Central District Municipality in the North West Province. Service delivery in general, as perceived by communities, has been a serious dilemma for most South African local municipalities. Factors in service delivery, as applicable in service marketing, have been examined through a detailed SERVQUAL research method. The focus areas have been service quality dimensions: • Reliability : the ability to deliver the promised service dependably and accurately; • Responsiveness : willingness to help and provide prompt customer service; • Assurance : knowledge, courtesy and ability of service providers to inspire trust and confidence • Empathy : caring and individualised attention given to clients; and • Tangibles : appearance of physical facilities, equipments, personnel and written materials. All five local municipalities in the Central District were involved in the study, and the main findings indicate that the residents in all the affected municipalities do not have confidence in the local government for service delivery. All five municipalities performed badly on the aspect of reliability and there is negative perception on responsiveness and willingness to provide prompt service by all the municipalities. The municipalities are perceived not to be able to command respect and instil confidence on their residents. The performance on empathy, where individual customised services are expected is poor. It is only on tangibles, where physical facilities are regarded as satisfactory. It is recommended that all municipalities should look inwardly and improve on their capacity on skills, financial management as well as bench-marking with international cities and towns for effective municipal service delivery. Service marketing as a management principle should be implemented immediately to save the current situation of loss of clientele and customer confidence. Other areas of quality improvement to be looked at are Total Quality Management and Work Improvement Team Strategy. / (MBA) North-West University, Mafikeng Campus, 2006

The restructuring of state assets was expected to contribute towards black economic empowerment and a broader redistribution of wealth to those who were previously excluded from participating actively in the economy of this country. However, there have been several accusations leveled at government. Some people believe that privatization of state assets has benefited a few. This has led to the enactment of the Broad based black economic empowerment act. There is also a concern from the communities and unions that privatization of state assets will result in poor service delivery and unemployment. The study was conducted through a quantitative methodology. The final questionnaire was administered to 40 taxi owners, 20 government employees, 20 contractors, 20 business owners and 40 local residents. Out of the 140 people, II 0 responded, thus a 79 % response rate, all was used for data analyses. The various variables (responses to individual questions) in the questionnaire were arranged to obtain a rating for each dimension covered. This procedure assumes equality of interval of the Likert scale and therefore the data is regarded as the least interval data (rather than ordinary data). The findings on the study showed that majority of the respondents were not in favour of privatisation. Recommendations made were as follows, the government through its education programmes in schools and in Adult Basic Education and Training (ABET) canters must educate citizens about socio-economic and political issues as well as familiarizing them with the government's macro - economic policy, in particular the GEAR policy. The government should only make partial privatization, and not complete/ whole privatization. / (MBA) North-West University, Mafikeng Campus, 2006

From the abstract: In the layered sequence of the Bushveld Complex a number of distinct, but possibly genetically related groups of transgressive, postcumulus, ultramafic and mafic rock are recognised. The main part of this thesis investigates a suite of postcumulus rocks for which the name iron-rich ultramafic pegmatite is proposed. The majority of iron-rich ultramafic pegmatite bodies examined are from the upper critical zone of the layered sequence at Rustenburg Platinum Mines Amandelbult Section, in the northern sector of the western Bushveld Complex. Field relationships imply that the iron-rich ultramafic pegmatites should be considered as an integral feature of the layered sequence, even though they transgress the cumulates. Consequently, this thesis also includes a study of the cumulate sequence at Amandelbult. A second group of postcumulus, ultramafic rocks which is investigated comprises latiniferous ultramafic pipes; the Driekop pipe has been selected as a case­ study. This thesis is presented in four sections, namely, an introduction and verview, and studies on the Driekop pipe, the cumulate sequence at mandelbult and the iron-rich ultramafic pegmatite suite. A new classification scheme of discordant bodies of postcumulus, ultramafic rock in he Bushveld Complex is proposed (see also Viljoen & Scoon, in press). In he scheme presented here, two main varieties of postcumulus, ultramafic rock re recognised, namely, non-platiniferous magnesian dunites and iron-rich ltramafic pegmatites.

This study of the lower part of the Rustenburg Layered Suite in the Western Bushveld Complex is based mainly on drill core samples from three localities, which are approximately 130 km apart. The NG-sequence, situated in the northwestern sector of the complex (Union Section, R.P.M.) extends from the floor of the complex to the base of the upper Critical Zone. The sequence is ca. 1800 m thick and it comprises mainly ultramafic cumulates, namely pyroxenites, olivine pyroxenites, harzburgites and dunites. Norites and anorthos ites are present only in minor proportion. Within the upper half of the NG-sequence ten prominent chromitite layers are correlated with the LGI MG4-interval. Correlation is also established between published sequences and the two other sequences studied, located 8 km and 55 km, respectively, east of Rustenburg. Whole-rock chemical data (major and trace elements), microprobe and Sr isotope data are presented. Petrographic studies provide modal analyses and measurements of grain size. All petrographic, mineralogical and other geochemical data point to an origin of the cumulates of the NG-sequence by crystallization from liquids of the U-type lineage and derivatives thereof. No evidence is found for the involvement of parental liquids with a distinctly different composition or crystallization order (A-liquids). However, subtle compositional variations of the parental liquids are evident in slight changes of the Cr content in orthopyroxene or in variations of Sr isotope ratio. The NG-sequence is characterized by intervals with reversed fractionation trends caused by repeated influxes of pristine magma (during periods of high magmatic activity) resulting in a high degree of rejuvenation. These intervals are overlain by others with a normal fractionation trend, interpreted as cumulates formed in periods with low or no magmatic activity, in which fractional crystallization controlled bulk composition of the evolving liquid. The Lower Zone in the NG-sequence is dominated by a progressive shift towards more primitive compositions, while in the Critical Zone fractionation was the major operating process in the magma chamber. However, during deposition of the pyroxenitic lower Critical Zone several replenishment events occurred, during which fresh Cr-rich magma was emplaced. Massive chromitite layers were deposited after mixing between the newly emplaced magma and the resident residual liquid shifted bulk compositions into the primary field of chrome-spinel. Cumulus plagioclase crystallized after bulk composition of the residual liquid was driven to the orthopyroxene plagioclase cotectic by continued fractional crystallization; this occurred once in the Lower Zone, yielding a single, thin norite layer, and again in the upper Critical Zone of the NG-sequence. A facies model is proposed based on the stratigraphic and compositional variations along strike in the Western Bushveld Complex. This model explains the variations by means of the position of the sequence with regard to a feeder system. The olivine- and orthopyroxene-rich, but plagioclase-poor NG-sequence represents the proximal facies, while the SF-sequence (poor in ferromagnesian phases, but plagioclase-rich) is developed as a distal facies, close to the Brits graben.
