  • Description: The construction industry is vital to the existence of other industrial sector and provides the environment under which other sectors operate. It is the largest industry and contributes about 10% of the gross national product (GNP) in industrial-ized countries. It also plays a major role in development and reaching the goals of society. The current study aims to establish the factors required in the manage-ment of good site management on construction sites in Swaziland. The study is conducted with reference to existing theoretical literature, published and un-published research. The study is mainly a literature review/survey on site man-agement practices on construction sites. Findings emanating from the study reveal that realistic studies have identified a number of problems on site management practices such as management and administration problems, technical problems and communication problems. It also indicates that site management involves a mixture of activities which turn basic sources to a finished product. The study presents a strong background on site management practices on construction sites in the Swaziland construction industry.

  • Description: Abstract: The rotating cylinder electrode (RCE) is one rig constructed and designed to study the behaviour of the material under the effect of flow. The behaviour of hot and cold rolled UNS S32205 duplex stainless steel (DSS) in erosion-corrosion (EC) conditions were studied to monitor the material loss and surface degradation. The impact is highlighted and explained with the aim to offer better understanding regarding degradation phenomena. Mine water solution containing silica sand particles (SiO2) was the environment of interest for this study. Both gravimetric and electrochemical methods (potentiodynamic polarisation (PP) and open circuit potential (OCP)) were adopted for the erosion-corrosion behaviour of the alloys. The cold rolled material displayed better resistance to erosion-corrosion at all speed tested in comparison with hot rolled material. The surface morphology for both materials revealed erosion dominating the erosion-corrosion process with minimal evidence of pitting. The hardness of cold rolled sample showed higher hardness as compared to hot rolled due to the impingement by sand particle hence better resistance to erosion-corrosion. The wear corrosion mechanism displayed grooving on the material surface especially at a higher speed. The effect of particles in wear mechanism play an important role. The electrochemical results showed increasing corrosion rate as the rotating speed of the electrode increased. The higher pH of mine water solution resulted in the passivation of the sample. The analysis trend was not surprising as the vulnerability of the surface layer increased with increasing velocity under the subjected conditions. Aggressive conditions and sand concentration are good enough to prove relation between wear rate and corrosion rate. The environmental impact was not aggressive enough to create much interferences hence the surface deterioration was not severe in all analysis. , M.Ing. (Engineering Management)

  • Description: Abstract: Purpose of this paper: The aim of this study was to investigate the benefits of Life Cycle Assessment (LCA) for buildings across their life-cycles in South Africa. Design/methodology/approach: To achieve the objectives of the study, a critical review of the literature was undertaken, coupled with a questionnaire survey to collect the primary data on the benefits of the LCA methodology for buildings across their entire life cycle. Through the review of the literature; the five major benefits of LCA for buildings were identified. This provided the basis for the formulation of the questionnaire. The questionnaire was distributed to all the professionals involved in the construction industry. The targeted number of respondents was 150; but only 116 questionnaires were returned. After a careful examination of the received questionnaires, only 98 were usable; and these formed the basis of the data analysis for the study. Findings: The findings from the questionnaire survey revealed that the participants agreed that the use of a life-cycle assessment would improve building designs by making them more environmentally friendly, thereby building construction-project efficiency amongst others. The lowest-ranked factor was construction business-marketing territory; and it was ranked number 15. Value of the study: The study contributes to the body of knowledge on the benefits of life-cycle assessment in the South African construction industry.

  • Description: Abstract : In the face of slowing economies globally, the construction industry faces many challenges such as socio-economic stress, resource shortages, institutional weaknesses and a general inability to respond to key issues. These have intensified and become more severe in recent years. Empirical research in supply chain management points to barriers that limit construction industries in developing countries such as South Africa. This paper aims to explore supply chain constraints in the South African construction industry. Relevant literature was reviewed and insights from 15 experienced supply chain practitioners were elicited by means of semi-structured interviews. Content analysis was employed using the ATLAS.ti (version 7) software to analyse qualitative data. Six themes emerged from the interviews, which include lack of investment in supply chains, lack of supply chain innovation process constraints, supply chain change management, supply chain collaboration, supply chain leadership, and time management. It is recommended that construction companies adopt supply chain management systems, integrated solutions, and collaborative project management tools and technologies.

  • Description: Abstract: Collusion is an unscrupulous and anticompetitive practices among construction stakeholders which has adverse effect not only on the integrity of the parties or people but also on the overall performance of construction projects. In view of this and in order to ensure healthy competition and alliance among construction stakeholders, this study assessed various measures that can be adopted to minimize or eliminate the practice of collusion in the construction industry. The measures were extracted from existing literature materials and questionnaire was adopted as a means of data collection using a 5-point Likert scale. Using convenience sampling, 49 questionnaires were distributed, 43 were retrieved while 41 were found worthy of further analysis. Among other measures, people involved in construction process including the professionals should be encouraged to report any suspicious acts and transactions including collusion practices, and procurement procedures for construction projects should be open and transparent. There is a need to blacklist and deregister professionals and companies that are caught in the act of collusion as this will enhance project performance and subsequently improve the image of the construction industry. Punishments for the offence should be well documented and there should be strict enforcement of the discipline and regulations when a company or individual is found culpable. This study will help regulatory bodies shouldered with the responsibilities of regulating construction activities - including that of the stakeholders - in their quest to reduce or eliminate the practice of collusion in the construction industry.

  • Description: Abstract: Construction industry globally is bemoaned by project delays despitethe importance of the Industry in most of the countries. In context of this sentiment this study examined the causes of construction project delays, the effects of construction projects delays, and strategies to improve construction projects delivery.A quantitative research methodologywas used.Questionnairewas developed from literature review. A total of76 conveniently sampled respondents were sent the questionnaires. Forty two useable questionnaires were returned representing response rate of 55.26%. The respondents were concentrated in Gauteng province in South Africa. The questionnaire consisted of twenty two factors defining causes of construction project delay, six factors related to effects of delays and ten proposed strategies to improve project delivery. The statistical parameters used were mean score and percentage and were computed using excel statistical method. The findings indicated that the most common causes of delay reported were improper planning, poor site managem ent and supervision,poor communication, skills shortages and corruption. The most common effects of delay were cost overrun,timeoverrun,disputes, litigation and total abandonment. Lastly the five highest strategies toimprove project delivery established were complete and proper design at the right time, site management and supervision,proper material procurement, clear informationand proper communication channels and frequent co-ordination between the parties.The study suggested that the constructioncompanies should concentrate on the strategies inorder to stifle project delay.A modelto reduce or prevent delaysfrom occurringonconstruction projects is advocated.

  • Description: Abstract: Building Information Modelling (BIM) is a concept that has been defined as a technology that digitally constructs an accurate virtual model of a building. BIM can be defined as an IT enabled approach that involves the application and maintenance of a fundamental digital representation of a building and all its information throughout the different stages of the project. This study assesses the ways to overcome the barriers hindering the adoption and implementation of BIM in the South African construction industry. The data used in this paper were derived from primary and secondary sources. The primary data tool (questionnaires), was designed based on the related literature that were reviewed. The questionnaire was distributed to construction professionals in the South Africa construction industry, facility managers, and academics who have are scholars on BIM in the South African construction industry. The questionnaires were analysed using descriptive statistical procedures. The findings revealed that a lack of skills, education, and knowledge of BIM are the biggest barriers to the adaptation and implementation of BIM in South Africa. Furthermore, the results also show that educational and skill development initiatives are widely considered to being the answer to the existing barriers to BIM adoption. Lastly, the study makes some recommendation on feasible ways of moving away from the common practice of construction process and to the adoption of BIM on construction projects in South Africa.

  • Description: The South African government has been implementing various small and medium sized contractor development programmes in an effort to redress the legacy created by apartheid government. The programmes fulfil such an objective through awarding construction projects to the historically disadvantaged Black contractors to enable them develop competent skills, build viable construction firms, create jobs and redistribute wealth. A mentorship programme was put in place to assist the contractors with technical, managerial, contractual and business impediments they might be encountered in the project execution and in running the construction business. The main aim of the paper was to conduct an evaluation of the contractor development mentorship programme in South Africa using the Free State Province as a case study. Questionnaires were distributed to 120 small and medium contractors in the Free State Province, and a review of literature was undertaken. Financial factors were found to be amongst the leading causes of contractors’ failures. It was also established that educational qualification and experience in the construction industry have an effect in a contractor’s failure or success. A lot of contractors revealed that they were not exposed to the Contractor Development Programmes like in other provinces hence 74% did not participate in any contractor development programmes and only 26% did participate. The paper concluded with recommendations on how mentorship within the contractor development programme can be improved.

  • Description: Abstract: This paper examines the impact of ICT in professional practice in the South African construction industry. This is with the view that ICT utilization inprofessional practice has the potential to facilitate better decision-making ability and savings in operating costs, amongst others. The data for the study was derived from both primary and secondary sources. The primary data -was obtained through the survey method, while the secondary data -was obtained from the review of literature. Theprimary datafor the study -was collected through a structured questionnaire survey distributed to a sample of 37professionals in the construction industry. The results revealed that architectura engineering and quantity surveying functions have been largely computerised. However, data and document management is still done through the traditional -way of manual.filing. Therefore, because construction industry professionals are a rich source of information about ICT and its improvement within the industry, the study provide valuable insight into the cu"ent usage of ICT in construction professional practise firms, which thus reveals the level of ICT adaptation in South African CL Hence, this thus shows that ICT surveys can be used to determine the number of users of these systems, identify the core impacts ICT has had on day to day activities.
