  • Description: Abstract: Economic diversification is a key policy goal for the Government of South Africa. SMEs offer a feasible option towards the actualization of this goal. The expansion of construction SMEs in South Africa, however is constrained by lack of access to bank credit. This constrained access to credit is argued in the literature to be due to the credit rationing behavior of banks emanating from asymmetric information in credit markets. Constrained access to credit stifles the growth potential of this vibrant sector which is increasingly generating employment opportunities especially for young enterprises. Department of Trade and Industry (DTI, 2007). This study therefore investigated the factors that influence the credit rationing behavior of banks towards SMEs. A deductive methodological approach was used to examine this problem. The structured survey questionnaire was administered to 179 construction small and medium organizations to elicit relevant data about their credit rationing. Binary logistic regression was applied to determine the influence of demographic variables on credit rationing. The statistical package for social science version 22 was used.The study findings suggest that the experience of SMEs reduces their probability of being credit rationed by banks. From the bank perspective the experience of SMEs is determined from their ability to keep proper financial statements, the performance of their bank accounts with the banks, and their ability to make profits. This calls for capacity building of SMEs in areas of business management (including financial record keeping) if they are to be rated as credit worthy borrowers by the banks. From the SMEs perspective, there is need for banks to improve their efficiency in terms of reduction of loan processing time and cost of borrowing (i.e. interest rate). This will improve access to bank credit by the construction SMEs and promote their growth thereby stimulating economic diversification, employment creation opportunities, and poverty reduction in line with South African Vision 2020

  • Description: Abstract: The significant impact of construction projects on a nation has been characterized in literature in terms of infrastructure development and job creation. These projects are nevertheless associated with various risks that need to be managed to ensure successful delivery. Hence, the identification of these risk factors is of utmost importance. Therefore, this study aimed at assessing contractors‘ perception of critical risk factors in construction projects in Gauteng (South Africa). Explorative and questionnaire survey methods were employed to obtain data from literature and construction professionals all practising in Gauteng. Results revealed that supply of faulty materials, poor communication between involved parties, financial failure of the contractor, working at dangerous areas and closure were the five critical risk factors in construction projects. It is obvious from the results that the knowledge of the identified critical risk factors furnishes invaluable information to the construction contractor concerning what risk variables to focus attention on in construction activities. The paper contributes to the identification of critical risk factors in construction projects from an objective point.

  • Description: Abstract: The growth of small and medium-sized construction firms (SMEs) undoubtedly remains an important consideration within socio-economic activities in the Ghanaian economy. Literature has established both tangible and intangible benefits that emanate from the activities of construction SMEs within the sector. Further, literature has also not reached consensus on a unified definition of what firm's growth constitute. Firm's growth is rather considered from the perspective of both internal and external determinants which makes comprehending growth vague. This study, however, conceptualized the growth of Construction SMEs with details of firm's growth indicators. In order to establish the aim of the study, semi-structured interviews supplemented by a review of existing literature on firm's growth was adopted to drive similar and new constructs that have informed this study. The study provides a significant conclusion to the study which includes the main determinates of firm's growth such as the entrepreneurial feature of the firm characteristics and the business environment of the firm. Also captured in the conclusion are necessary growth barriers that must be controlled if growth within the construction SMEs in Ghana is to be achieved.

  • Description: Abstract: For clients, owners and financiers of construction projects, construction process signify a huge capital investment which translate into substantial fixed costs for their organizations. Value Management (VM) is a business strategy tool to ascertain whether construction of a facility will provide best function at the lowest possible cost. This study examines the contribution of value management to construction projects with a view to assessing challenges and measures to improve adoption and application of the discipline. Primary data were collected through well-structured questionnaires administered on construction professionals within the study area and Mean Item Score was used for data analysis. The major contributions of VM to the South African construction industry include optimize value for money, creates a clearer focus on the project objectives and works towards arriving at a more effective design. However, poor communication, lack of interaction and unwillingness of clients to pay for VM service, were the challenges affecting the adoption of VM. In order to improve construction project performance using the process of value management, orientation meetings should be duly organised, team structure should be finalised and team members must be appropriately selected for construction projects. Built environment professionals - including construction and project managers, should familiarize themselves with VM and strive for its full adoption and implementation for construction projects in order to achieve best value at the lowest complete life cycle project cost for construction clients.

  • Description: Abstract: The remarkably challenging features of the construction industry in the 21" century are globalization, the restructuring of the world economy, changes experienced in project financing and delivery systems, the pervasive utilization of information and communication technologies (ICT, and the increasing intensity of competition which threatens the growth, survival and profitability of engineering businesses with construction being the most affected. Marketing as a management function, which has been identified as imperative for businesses facing such challenges has not been welcomed by the construction industry. Marketing in consternation is marked by misconceptions, misperceptions, lack of understanding among others which are traceable to education and training of construction management team members. This paper examines the aspects of construction education that impacts negatively on marketing performance of construction businesses, namely content and structure of curriculum for construction education, availability of construction marketing research reports and teacher qualification for teaching marketing to construction students. Finding reveal that the content of construction marketing syllabus is outdated and fall short of elements necessary for effective teaching the state of the art marketing in construction. Paucity of construction marketing research and lack of general helpful literature remains a challenge. Qualification of teachers appears to be a big challenge. Urgent need exist for revision of existing syllabus, efforts at addressing research towards addressing existing challenges with marketing in construction and guidelines for preparing teachers for teaching marketing to construction students. Construction education consultants, curriculum developers, construction education and training institutions and similar professional organization will find this useful.

  • Description: Abstract: The Construction Industry is by nature one of the most diverse working environments. The South African Construction Industry is not an exception to this rule. The Industry has witnessed great diversity in its workforce mix at all levels since the return to democracy in 1994. Thus, peoples from erstwhile segregated communities are brought together to work in achieving a common project objective. The intricate influence of this cultural mix and the pressure it exerts paper provides insight into the influence of culture and cultural difference on teams working together towards project delivery. The study adopts a mixed method approach by use of interviews and questionnaires through a convenience sampling of construction professionals in the Gauteng Province, South Africa. Findings from this research confirm that factors such as sociability, masculinity, power, equity, individualism, avoidance, collectivism are cultural dimensions prominent in multicultural teams. The influences of cultural aspects that rank highest are irritation due to misunderstanding, encouraging team building, motivating workers to work harder. The study concludes that while a lot has been done in integrating project teams from different cultures in the South African construction industry efforts should be concentrated on mitigating the effect of masculinity and irritation due to misunderstanding. It is recommended that Project Managers and Construction managers should more sensitive to the influence of cultural dimensions and deploy cultural awareness and appropriate leadership styles in mitigating its effects while channeling the positive influences towards organizational benefits. This research has provided insight into intrinsic cultural dimensions among construction industry workers in the Gauteng Province of South Africa and provides useful policy input for the Construction Industry Development Board and industry practitioners at large. The research is limited to the experiences of Construction Industry professionals in the Gauteng Province of South Africa due to the constraint of time.

  • Description: Abstract: Leadership in construction health and safety (H&S) management has drawn great attention from scholars in the western world. This paper reviews existing literature on the role of project leaders in H&S management programmes and how their active involvement/ participation, from the inception of projects, could reduce the numbers of injuries and at-risk behaviors among workers. A review of existing literature was conducted from Google, ASCE and Science Direct. Findings revealed that positive H&S behaviour of workers could be influenced by: a) incorporation of H&S into the work programme by the project manager; b) facilitation of financial provisions for H&S into the contract documents by quantity surveyors; c) demonstration of commitment and visible H&S leadership towards workers‘ H&S by contracting firms at all levels of management; and d) key projects leaders‘ H&S leadership and behaviour. Client H&S visible leadership manifests through appointment of competent design team, allocation of adequate financial resources for H&S, and designing H&S into construction projects at the early design stage. These findings will increase awareness on the importance of leadership and commitment in improving H&S behaviour of construction workers on sites. The study recommends that key leaders on a project should demonstrate visible leadership and commitment towards workers‘ H&S. Keywords: construction, health and safety, leadership, project leaders, worker behaviour.

  • Description: Abstract: Performance of construction projects is an issue of concern, not only to contractors and professionals, but other stakeholders including clients, project sponsors and end-users. This is due to complexity of construction process, innovation in the use of raw materials and machinery, new construction management techniques and more importantly, variation in requirement from clients. Thus, this research evaluates factors affecting performance of construction projects from the perspective of consultants and contractors, in order to enhance the quest of the construction industry in contributing positively to the growth of economies. Using quantitative approach, data were collected through close-ended questionnaires administered on a group of learned and experienced consultants and contractors who are based within the study area. From the analysed data, there is a significant difference in the perceptions of consultants and contractors regarding factors affecting performance of construction projects. To consultants, general time factors and conformance to specification are the most important performance indicator for project success while from contractors' view, cost factors including delay in payment from owner to contractor is a major critical success factor. The two groups unilaterally agreed that bringing about the best planning and scheduling technique before and during construction would assist in improving performance of construction projects in the country.

  • Description: Abstract: Small and medium sized contractors represent the large number of construction companies in Nigeria. They play an important role in the construction industry. However, site fatalities and injuries cases among the small and medium sized construction companies still remain the most health and safety (H&S) issues around the world. This study seeks to examine the economic and social impacts of site accidents on the small and medium sized construction companies in Nigeria. Questionnaire survey was then structured from literature and administered to twenty (20) selected small and medium sized construction companies with not less than hundred (100) workers within the South-West Geopolitical zone of Nigeria. This was followed by interviews conducted with the owners/directors of the five selected companies and workers randomly picked among the selected companies. Data was electronically manipulated using MS Excel. From the analysis, the study revealed that site accidents contribute to loss of productivity, damage to plant and equipment, payment for settlements of injury or death claims, all these have economic impacts on the companies’ balance sheets. The study further revealed that site accidents lead to loss of customers’ confidence, tarnishing of image and loss of public confidence on the contractors, these are the social impacts. Nevertheless, there is a general lack of commitment to workers’ health, safety and wellbeing among the small and medium sized construction companies. The study concludes that site fatalities and injuries cases among the small and medium sized construction companies still remain the most health and safety (H&S) issues. The study therefore, recommends that contractors irrespective of their sizes should demonstrate visible leadership and commitment to workers’ H&S by training them on site H&S and providing adequate financial resources for improvement of site accidents.
