- Description: Abstract:It is a difficult task to attempt developing generic Key Performance Indicators for all the functions of Facilities Management services in all organization it serves. Nevertheless, the exercise is possible for organizations with similar objectives. For example, the objectives of Higher Education institutions revolve around teaching, learning and research that require functional infrastructure, technology and services. The client, end-users and service providers in these organizations can develop acceptable indicators for their operation of the support facilities and that will facilitate the creation of an effective benchmark. The modified classic Delphi technique was used in achieving the consensus of opinion from the participants. The findings revealed that there were convergence of opinion on the essential indicators that can enhance the provision, operation and management of the required support facilities for the effective performance of the core functions of Higher Education institutions. It was recommended that the research should be extended to cover all Higher Education institutions within and across regions for more comprehensive information

- Description: Abstract: Considerable research efforts abound on safety issues during construction phase of built facilities, but very low attention is paid to safety during operation phase; instead security occupies top priority. Responding to factors such as technological and increase in student’s population, many higher institutions globally are expanding their built facilities in terms of quantity, size and sophistication. There are many situations that infringe on the safety of the end-users; they include fire, natural and man-made disasters. The simplest approach to test the emergency preparedness of the end-user of the facilities as well as the adequacies of critical components of the built facilities is to simulate emergency through evacuation drill. Conducting evacuation drill in Higher Education institution is complex due to the composition of its constituency, multiple activities, time constraints and the human dynamics: some view evacuation drill as a wasteful exercise. The case study method of qualitative research is adopted; the data are collected through semi-structured questionnaire complemented with interview, observation and participation. The findings include evidence of the display of safety awareness documents, sensitization lectures and running mini evacuation drills in the different segment of the institution. Although the response rate to evacuation drill is low at the moment, with more commitments and advocacy it is possible to progress towards benchmarking the exercise with regulatory standards.

- Description: In framed reinforced concrete structure, the beams transfers the dead and live loads to the column and then to the foundation. When there are observed structural failure in the systems supported by the beam, especially where the beam has a large unsupported clear span at a lower level, before any further detailed investigations are initiated, the functional state of the beams should be ascertained. The correct diagnosis of the source of problem is essential for the design of effective rehabilitation scheme. Simple visual inspection corroborated with field test for true horizontality of the beam can provide the lead information that will guide the client on the scope of further investigations. The case study method of qualitative research was adopted to address the research questions, while the research data was collected by reviewing previous investigation reports on a three-storey building, physical inspection and conducting simple site experiment to identify the lead information. The research outcome reveals that the multiple cracks observed in the partition walls especially in the second floors were as a result of excessive deflections in the beams supporting the first and second floors. Based on recommendation, subsequent investigation confirmed this lead information and appropriate rehabilitation scheme was adopted.

- Description: The burden of translating the end-users’ project briefs into the development of functional support facilities that enhance the performance of the core functions of the organisation require the use of dynamic modern project management methods. In the course of developing capital assets, it is inevitable that original designs are modified, some sections redesigned while some facilities or components are out-rightly removed due to budgetary, time or other constraints. It is imperative, therefore, to incorporate the end-users into the development process, so that managing changes, trade-offs, commissioning and project close-outs will be smooth and enhance the achievement of customers’ satisfaction. Customers’ satisfaction, in the context of this paper, is viewed in the light of how effective and functional the completed facilities enhance the performance of the core functions of the organisation. The case study method of qualitative research was used in this research. The research data were collected through semi-structured questionnaire complemented with interviews. The thematic method was used to analyse the interview data. The client and end-users provided information on the level of their satisfaction with the performance of the capital development unit as well as identified some areas of concern that require improvement. Recommendations made include the use of Value Engineering as a project management tool; considered suitable for the management of design or scope changes and ‘trade-offs’, in order to improve on the level of customers’ satisfaction.

- Description: Abstract: Regionally, Southern Africa is facing many challenges with regard to the level of access to energy. The situation is most compounded in the rural areas where poverty and lack of development are taking place at a snail pace. In order to achieve and promote sustainable development, the use of solar energy has been regarded by the government of Zambia and the sub-Saharan African region as the best alternative to the current energy deficit that the region is facing. To begin with, the government of Zambia, in the last decade, has supported solar photovoltaic energy research and development. However, the country has had challenges with achieving the set targets of connecting 10,000 new household by 2013 and ended up reducing the target to 2500 households of which 500 household of the proposed target was connected in 2015. This review is a desktop study of the on-going research on the solar energy and policy analysis of Zambia. It reviews the current solar photovoltaic and renewable energy trends in Zambia based on secondary data collected from various literatures, reports, and local contacts. The paper also highlights some of the solar energy achievements and failures in Zambia such as the 50MW solar mini-grid with the lowest tariff of US$0.0602 unit per kilowatt-hour and as well as the efforts, the government of Zambia has made through the help of international donors and the World Bank to scale up initiatives. Finally, it has also discussed the Zambian government policies and initiatives to promote deployment of solar energy technologies in the country. The review of solar photovoltaic energy is vital, as it will help the decision makers and various stakeholders to understand the current renewable status, barriers and challenges in Zambia and find alternative ways to overcome these challenges and barriers.

- Description: This paper investigates the technical feasibility of microwave assisted artisanal mining in the production of Sandstone from QwaQwa in South Africa. It further discusses the cultural acceptability by the rural community of the synergetic application of the emerging technology (microwave energy) and the renewable resource (solar). Sandstone in QwaQwa, Free State is artisanally mined using chisels and hammers. This form of mining is extensively laborious and is normally accompanied by numerous casualties. The paper demonstrates the existence and the possible utilization of alternative methods including emerging technologies which are more productive, efficient, effective and sustainable. The solar energy systems are used to trigger the microwave magnetron which results into high energy microwave dosage. The dosage causes differential or selective heating on the rocks which culminate into rock breaking along the interfacial grain boundaries between the different constituting minerals. The data used in the analysis was collected by administering questionnaires to the artisanal mining community in QwaQwa and from observations made on site as well as desk top information obtained from secondary sources. The paper contributes to knowledge by drawing on the solar energy systems to generate the dosage required to trigger the microwave magnetron used to facilitate a more efficient and economical artisanal mining of sandstones. In conclusion the paper recommends to policy makers the application of microwave energy in mineral artisanal mining and processing instead of the manual chisel and hammer currently being utilized country wide. It then gives a detail analysis of the technical, scheduling and economic analysis of the sandstone artisanal mining in QwaQwa.

- Description: Abstract: The Delphi technique, as a research method for achieving consensus of opinion of participants, is sometimes seen as a less reliable research method because the participants do change their opinion from one round of the exercise to the other. Instead of seeing this as weakness, it is actually the strength of the technique. The controlled feedbacks allow participants to view their individual submissions in the light of the whole group. The Delphi technique is about the only research method that allows participants to interact with the opinion of each other, without coercion, adjust ones position where necessary and yet retain anonymity. Thoughtful selection of participants and effective communication throughout the exercise ensures that the outcome of the exercise is truly a consensus opinion of the group that can proffer appropriate solution to the research question. The participants for the Delphi exercise, being reported, were chosen from the strategic and tactical levels of leadership of the client, end-user and the service provider. Though participants changed their opinion from one round to the other; the net result showed a more refined selection of appropriate Key Performance Indicator, without evidence of complicity or coercion.
