- Description: Abstract : This research examines the potential impact of domestic anaerobic digester (AD) systems adopted in Bangladesh and similar developing countries. Cattle dung and poultry litter feed stocks were specifically investigated, because these were freely available and plentiful to people living within agricultural areas of rural Bangladesh. Data was collected to ascertain whether these two representative AD facility types provide tangible social, economic and environmental impact that benefits homeowners. Primary quantitative and qualitative data was obtained by field data collection, and meeting with expert groups and stakeholders. Empirical analysis conducted revealed that variations were found in the biomass feedstocks available on different sites but also differences were apparent in terms of the operations and maintenance (O and M) systems of the biogas plants operated. The biogas and methane yield variation was also measured, and variations were found in the cattle dung and poultry litter AD yield capacity. Overall, 64% of feedstock was utilised, 91% of biogas plants remain underfed and energy yield efficiency was 57% from cattle smallholdings’ AD and 28% from poultry farms’ AD. These results showed that small scale AD can offer a significant impact upon rural lifestyles through augmented economics, improved social activities, relationship building with neighbours and improved lifestyle achieved via time savings accrued. These results could help rural entrepreneurs, AD equipment providers and government institutions to develop a road map to implement future AD installation on a much wider geographical scale.

- Description: Abstract: Sustainable construction practices not only benefits government, environment and occupants but it secure the earth for future generations to come. Thus the paper discussing sustainable construction practices challenges in the construction industry of South Africa. Structured questionnaires were distributed to different construction companies and construction professionals. From the 75 questionnaires distributed, 60 were brought back and they were all valid and usable. Findings from the survey results obtained from the chosen respondents revealed that the is a lack of training in an organization regarding sustainable construction, lack of awareness of sustainable construction practices, lack of sustainable environmental materials, changes in material prices and escalations, lack of accessible guidance, lack of technical skills, resistance to change in adoption and material scarcity. The construction industry needs to promote and create more workshops on sustainable construction practices so that more stake holders would be aware of it benefits and incentives should be provided to organization that are implementing sustainable construction. Furthermore, the implementation of construction principles can be achieved successfully if all the construction stakeholders participates from design to completion of the project with the assistance of knowledgeable project manager on sustainable construction practices. The study will contribute to the body of knowledge by increasing more awareness of SC to professionals in order to be implemented.

- Description: Abstract: South Africa is confronted with huge infrastructure service delivery backlogs, which has a negative impact on the country’s economic growth and improvement of the lives of its citizens. The infrastructural backlog cannot be sufficiently addressed by government alone, as it requires a collaborative effort from both the public (government) and private (business) sectors. The study examined the contribution made by Private Public Partnerships (PPPs) in delivering infrastructure projects. The data used for the study were derived from both primary and secondary sources. The secondary sources were review of literature and primary data were obtained through the use of structured questionnaires which were distributed to construction stakeholders in the public and private sectors, who were involved in the PPP’s projects in South Africa in the Gauteng province. A total of 90 questionnaire were distributed and 80 came back and used for the study. The study revealed that: PPPs speed up the infrastructural projects; completes the infrastructure projects much quicker than the traditional method; PPP increase the effectiveness of projects; completes work on time or even ahead of schedule; greater cost transparency; cost savings; reduction of life-cycle maintenance costs; reduction of the service delivery backlog, etc. The research has revealed that the projects delivered through PPP are of great quality and they are maintained well.

- Description: Abstract: Public-Private Partnerships (PPPs) play an important role in improving the quality of infrastructure service delivery in different countries. In the construction industry, PPPs contribute to skills transfer by the private sector to the public sector and achieving greater efficiency by reducing government bureaucracy and financial burdens. However, these partnerships have challenges that hinder the implementation and delivery of infrastructure. This research examines challenges encountered in the implementation of PPP in construction projects. The study is a literature review/ survey on the challenges faced with the implementation of public private partnership in improving infrastructure service delivery on projects. The study is conducted with reference to existing theoretical literature, published and unpublished research based on international context. However, the challenges specifically are based on literature in Swaziland to identify the challenges they face and the way forward. Other scholars'works were critically examinedtodeterminethe views on the subject. The research revealed that on the political level, there are high expectations with concerns that officials expertise to handle PPP projects are not sufficient, Private sector stakeholders were concerned about the possible dominance of foreign companies. Moreover, labour feared negative consequences for workers, and part of financial sector did not see enough opportunities for PPP in Swaziland. Lack of common understanding and coordination, insufficient planning capacity and structuring support were amongst the challenges faced by PPP in Swaziland.The study will assist the Swaziland Construction Industry in improving their services in terms of delivering construction project timeously since particular strategies can be developed to overcome the identified challenges.

- Description: Abstract: There are numerous overlaps in terms of relating the differences between leadership and management. Jarad (2012) viewed leadership as a subset of management and that both are important to facilitate organizatio0nal performance. However, the construction industry is well defined with the inclusion of both these roles. It is to this end that the study presents a theoretical framework relating to the difference between leadership and management. Design/methodology/approach: The study is conducted with reference to existing theoretical literature on leadership requirements for the construction industry. Findings: Literature findings revealed that, leadership includes social influence and the leader's role in setting a purpose or vision of change, whereas management associates with fulfilling organizational goals and processes. Originality/value: The study explores the difference leadership and management. The study further gives findings relating to management and leadership, thus adding value to the body of leadership and management knowledge.

- Description: Abstract: Cost of poor quality (COPQ) in the construction industry is a serious problem that the industry is faced with, due to failure in preventing wastage and defects during construction work. The cost of poor quality remains hidden and eats up to 40% revenues of the construction enterprise. Hence, the study investigated the critical success factors that reduce poor quality in construction projects according to the perceptive of construction professionals in the Swaziland construction industry. This research adopted quantitative research and 50 useable questionnaires were used as an instrument tool for the study. Random sampling method was used to select the respondents in various construction companies. Cost of poor quality impact the construction industry of Swaziland’s and construction companies have to reserve funds for such occurrences, since poor quality cannot be tolerated and contractor have to rectify at own cost. Another challenge would be under-pricing the construction project and rectifying construction mistake it becomes a big problem for the contractor. Findings revealed that are a lot of success factors that can be used, it’s just a matter of the implementation of the success factors in the project. The role of the managers in construction projects is still under looked and therefore, this can be a problem if it is not attained to. The study revealed that are a lot of success factors such as the use of quality management system and the critical success factors can actually help eliminate poor quality in most construction projects of Swaziland. The implementation of quality management systems at the beginning of the project and encouraging team work in the project could assist construction projects.

- Description: Abstract: A mentoring program is a tool that is used to increase the skills of construction graduates. Many construction graduates struggle to perform their duties in the industry due to lack of experience and skills. The government and other construction firms implemented mentoring programs to utilize them as the solution to increase the skills of construction graduates in the industry; however a number of construction graduates participate in mentoring programs but even after completing mentoring programs they still need further training to enhance their skills. This implies that the implemented mentoring programs have not been effective. Many mentoring programs are not successful and they don’t produce the expected results. The aim of the paper is to look at the effectiveness of mentoring programs for construction graduates...

- Description: Abstract: The growth of Small and medium-size firms cannot ensue without the entrepreneurial features and the environment that the firm operates. The entrepreneurial characteristics, therefore, are vital due to the unique individualism of firm owners or sponsors. Construction SME growth-oriented firms are a significant contributor to Ghana's economic gain. Conversely, the concept of growth varies from one entrepreneur to the others depending on the exhibited skills by the entrepreneurs, hence entrepreneurial features. Numerous factors influence the entrepreneurial features as a factor of firm’s growth. Some are of the factors are established and categorised as having strong influence while others are classified weak. This study, therefore, adopted the confirmatory factor analytical technique to justify the factors after exploring. To achieve the goal of the study, respondents such as firm owners, SME managers and construction professionals engaged by SMEs as the population were administered with questionnaires. In all, 315 questionnaires were given out in the form of semi-structured structured, but only 228 were retrieved for analysis representing a responds rate of 72 percent. The study established Cronbach alpha and composite reliability values that predicted the entrepreneurial feature as a subsequent determinant of firm’s growth. Additionally, the hypothesis was supported statistically suggesting that there is a direct relationship between entrepreneurial features and firm growth.

- Description: Abstract: Total Quality Management (TQM) is a philosophy that involves every organization in the industry in the effort to improve performance. The concept is an integrative management principle for continuously improving the quality of products and processes to achieve customer satisfaction. To achieve this concept required a clear establishment of Critical Success Factors (CSFs). However, lack of clear establishment of CSFs for the implementation of TQM in the construction industry has led to failure of the system. In the pursuit of performance excellence in the construction industry and with an increasing awareness of construction quality, construction firms have no option than to implement TQM with clear CSFs.

- Description: Abstract: Increased demand for building infrastructure delivery advocates for innovative construction methods. This paper examines the concept and application of Modern Method of Construction used in the South-West UK, and the Innovative Building Technologies in South Africa. It assesses the methods, current use, off-site manufacturing; identifies and evaluates aspects of the construction process typically used with the aim of identifying and analysing the barriers and merits for the adoption in the Ghanaian construction industry. The research design adopts a qualitative method and case study of two housing projects as part of a broader study to determine an appropriate innovative construction method to meet project targets of time, cost, quality and improved delivery for the Ghanaian industry. The study finds; convenience; speed; reduced cost and improved delivery as the key success factors though there is less than 5% use of the innovative methods in the entire sector for mainly repetitive housing, schools and hospital projects. Negative end-users perception of building quality and low satisfaction; less government intervention through education; promotion; availability of off-site contractors and materials were also the barriers identified. Management contract is adopted in most cases hence the risk transferred to the management contractors. Lessons learnt are outlined and recommendation made for government action plans to mitigate the barriers during its implementation in the Ghanaian construction industry.

- Description: Abstract: Workers inability to act according to laid down rules and regulations within the industry have invariably contributed to their unsafe actions leading to accident. The purpose of the study was to determine safe acts of workers towards health and safety (H&S) compliance. Delphi survey method of data collection was adopted for the study. Experts were asked to complete the Delphi questionnaire survey based on the impact of given factors in predicting safe act of workers towards Health and Safety compliance. The ratings were based on either the impact was considered to be very high or high. Data obtained was analysed and results were presented in a table and a chart. Findings from the study show that only three measurement variables (ensure equipment or tools are in good condition before usage, ensure the use of personal protective equipment (PPE) and ensure proper positioning of tasks) were considered by the experts to have reached consensus with IQD cut- re. Further findings showed strong consensus with very high impact (VHI: 9.00-10.00).Results from the Exploratory Factor Analysis (EFA) showed that only five indicator variables (SAW10,SAW 16,SAW7, SAW8 and SAW9) were considered as determinant of Health and Safety compliance. Further findings showed that one indicator variable (PPE) was found to be common in the Delphi survey and EFA results.The factor loadings for all items were greater than 0.5593.This findings indicate that high priority was given to SAW 10 in determining Health and Safety compliance in the construction industry.
