- Description: This study investigated the causes and effects of the underutilisation of Information Communication Technology (ICT) in the building section of the Amathole Region. The construction industry’s daily processes demand both heavy usages of data and data communication between project participants to meet client requirements. This industry is characterised by inaccurate and untimely communications that often result in costly delays and extensions of the project timeframe. ICT is a potential solution to this problem. The objectives of the study are, therefore, to determine why the above, a technically skilled occupational government institution in the Eastern Cape, does not employ ICT efficiently and optimally during this time of the looming global fourth industrial revolution. The literature review detailed the causes of and impact level of ICT’s utilisation and its potential benefits. For data collection, the researcher held unstructured interviews with a Chief Quantity Surveyor, Chief Architect, Engineer, Building Inspectors, and a Quantity Surveyor who dealt directly with construction projects. The key findings revealed that a lack of understanding of existing and newly available ICT software and hardware technology existed amongst certain senior officials within the building technology. The previously alluded, combined with the fear of the inability to learn and apply such new technology, has led to a culture of resistance to change from these more senior officials to utilise applications such as AutoCAD. The above-mentioned resistance, has also triggered the prevention of access to and lack of ICT resources, training, and inadequate funding, thereby eventually resulting in the underutilisation of ICT within the whole building section. This change also adversely affects all officials, especially the junior officials who have graduated using the most recent ICT technology during their studies. The researcher deduced, from the above findings, that adequate change management and continuous development, combined with the allocation of proper resources, would be necessary for all staff members. It was also determined that investments had to be made in the ICT equipment through the provision of a sufficient budget in the building section at AR.

Grapple cable yarding: a productivity model for fast-growing tree plantations in Sarawak, Malaysia

- Description: Today, the two most important tasks faced by harvesting foresters and contractors are selecting the equipment and systems best suited to the site, and then to use this equipment in the best way possible (MacDonald, 1999). Experts estimate that the importance of tree plantations will continue to grow and that by 2050 75 per cent of the global fibre supply will be sourced from dedicated plantations (Ragauskas et al., 2006). To meet this growing demand plantations will most likely expand to steep slopes due to the priority given to agricultural and urban development, on flat land. New technological advancements in both cable yarding and ground-based harvesting systems has to a certain extent provided forest engineers with more options to choose from. Whether considering these options individually or in combination, they will have to make good choices in order to realise the full potential of forest plantations. One of the most promising techniques consist of an excavator-based unguyed yarder equipped with a new radio-controlled grapple carriage, fed by another excavator stationed on the cut-over. This system is very productive, avoids in-stand traffic and removes operators from positions of high risk. This long-term study was conducted on 12 different teams equipped with the new technology, operating in the fast-growing Acacia mangium plantations of Sarawak, Malaysia. Data were collected continuously for almost 8 months and represented 555 shifts, or over 55,000 yarding cycles - each recorded individually. This large data pool allowed for the development of robust models for system production, utilization and availability estimated respectively at: 63 m3 per productive machine hour (excluding all delays), 63 per cent and 93 per cent. The study also determined the effects of yarder type and team competence on productivity and utilization. Regression analysis of experimental data yielded a strong productivity forecast model that was highly significant, which accounted for 50 per cent of the total variability in the dataset and was validated with a non-significant error estimated at less than 1 per cent. The models reported in this study are especially robust, because they were obtained from a long-term study that covered multiple teams and accumulated an exceptionally large number of observations. While gained specifically on one yarder make (Alpine Yarder) and a specific plantation type (Acacia mangium), the information in this study can be extended to other similar machines and plantations, because the sheer volume of data allows cautious generalization. The teachings of kaizen, which suggest small-step work improvements, was adopted in order to propose the process of possible improvements, by combining elements of other harvesting systems as shown in Figure 1 below (Vorn Industries, 2017). Forestry is essentially a problem of transportation (Schenck, 1911) and the efficiency of such a transportation system will ultimately be determined by technology developments which drive system productivity (Ger & Klvac, 2014). Therefore, when we talk about systems for the future we should view them not as predictions or as prescriptions but as options that may be selected or rejected (Wood, 1979).
