South Africa is a developing country that invests billions of rands annually in the construction industry. This industry consumes resources and, inevitably, waste is generated during the process. Although numerous approaches have been developed to improve quality, efficiency, and effectiveness in this industry, lean principles offer the ability to minimise and/or eliminate non-value adding work, thus increasing value for the client. This paper highlights the lean construction tools currently used worldwide, and the benefits of adopting lean construction. The study surveyed publications on the application of lean principles in the construction industry, and identified tools yet to be implemented in the South African construction industry with specific reference to electrical and mechanical engineering services. The study used a systematic review methodology to identify different lean construction concepts, and developed a lean implementation framework. The framework was then evaluated using a local case focusing on electrical and mechanical engineering services in the construction industry. The improved framework after evaluation consists of eight steps.
South African industry faces immense global competition from developed countries such as Germany probably because of the adoption of lean manufacturing techniques by the latter. This study is a survey on publications concerning implementation and adoption of lean manufacturing in South Africa. To assess South Africa with regards to research publications on lean manufacturing, a benchmark exercise was conducted with Germany for the period 2014 to 2015. The study concludes by highlighting the gaps identified during this survey and recommendations.
OPSOMMINGDie Suid-Afrikaanse industrie staar hewige globale mededinging vanaf ontwikkelde lande soos Duitsland in die gesig, waarskynlik as gevolg van die aanneming van lenige vervaardigingstegnieke deur die laasgenoemde. Hierdie navorsing is ʼn beskouing van die publikasies oor die implementering en aanneming van lenige vervaardiging in Suid-Afrika. Om Suid-Afrika te beoordeel aan die hand van navorsingsuitsette met lenige vervaardiging as die onderwerp, is ʼn maatstaf oefening uitgevoer met soortgelyke publikasies in Duitsland in die periode van 2014 tot 2015. Die navorsing lig die gapings só geïdentifiseer uit en maak aanbevelings hieroor.
The paper focuses on the evolution of the South African iron and steel industry from the industrial engineering perspective. The earliest ironmaking in South Africa dates to the fifth century CE; but the major evolution of the industry began in 1882 and, by the year 1934, steel production from native ore was in full swing. The study highlights the major developments in South Africa's iron and steel industry, and ends by exploring the extent of the application of industrial engineering techniques to published research into the steel industry.
OPSOMMINGHierdie artikel fokus op die evolusie van die Suid-Afrikaanse ysteren staalindustrie vanuit ʼn bedryfsingenieurswese perspektief. Die vroegste yster produksie in Suid-Afrika dateer terug na die vyfde eeu VC, maar die hoofsaaklike ontwikkeling vind sy oorsprong in 1882 en staalproduksie vanaf ystererts was teen 1934 in volle swang. Hierdie studie lig die hooftrekke van ontwikkelings in Suid-Afrika se yster-en staalindustrie uit en sluit af deur die omvang van die toepassing van bedryfsingenieurswesetegnieke tot gepubliseerde navorsing in hierdie industrie te ondersoek.
