This study aimed to develop and ascertain the elements that should be included in a social media-marketing framework for small-scale contractors in the Zambian construction industry to improve their visibility consequently their marketing and performance. The framework was developed through a mixed method sequential approach using observations and a survey of 35 firms already using some form of social media marketing using a questionnaire comprising open and closed ended questions which was conducted to ascertain the components needed to promote social media marketing among small-scale contractors. For any firm to be successful in using social medial marketing; audience assessment, content generation as well as Return on Investment evaluation were found to be more relevant than influencers, tone and voice. However, monitoring of the client posts and the competition was found to be an area needing much attention for subsequent marketing.

Realizing that huge sums are spent by the government in providing infrastructure, the research focused on assessing the feasibility of reducing risks on infrastructure projects through IRM. To achieve this, secondary data was obtained from an extensive literature review while primary data was through the use of a questionnaire survey to consultants and contractors. This revealed that the management of risks in the Zambian Construction Industry (ZCI) on projects is hugely hampered by the over-reliance on the traditional method of procurement in which teams are segregated resulting in adversarial relations. Hence, the reduction of risks on projects cannot be effectively achieved traditionally due to fragmentation of the parties involved. There is needed to change the traditional procurement path as it does not encourage integration of project parties in ord...

The study was motivated by the accumulation and non-use of copper tailings in dams among them tailing dam 25 also known as TD 25 in Kitwe city of the Copperbelt province in Zambia that take up approximately 111 hectares of unused land. Design/methodology/approach Laboratory experimental approach of concrete production based on water/cement ratios of 0.3 and 0.5 was used because this was an exploratory study designed to establish the primary performance of concrete. In total, 30 concrete cubes were cast based on the two water-cement ratios. In total, 0% to 30% partial sand replacement with copper tailings was used in both mixes with the 0% copper tailings replacement being the control mix and reference point. Other concrete tests included workability, density, compressive strength and element composition analysis. Findings Results re...

Rice husk is a by-product from the rice mill process, with an approximate ratio of 200 kg rice husk per one tonne of rice produced. This experimental study aimed to investigate the integrity of concrete produced in Zambia using rice husk ash (RHA) to partially replace cement. The primary goal was to carry out a cost–benefit analysis on the use of RHA in concrete. RHA was used to partially replace cement with ratios of 10 %, 20 % and 30 %. The 20 % cement replacement mix produced the optimum 18 MPa concrete strength results at a 0.5 water/binder ratio. This translated in cost reduction of concrete by 12.5 %, which is particularly significant for higher concrete volumes. The produced concrete is suitable for lightly loaded structures, such as foundation footings, surface beds and walkways to benefit low-income...
A retrospection of methodological pluralism in the Journal of Financial Management of Property and Construction (2005-2020)

Design/methodology/approach Content analysis of 258 research papers published in the Journal of Financial Management of Property and Construction was carried out, enabling the exploration of research approaches, epistemology, strategies, data collection and data analysis methods used in addressing problems researched in the area of financial management of property and construction Findings The findings show that quantitative approaches and methods dominate, whereas qualitative and mixed methods were prominent in-depth understanding of a topics were needed. Interestingly, almost a third of the publications did not adopt quantitative approaches. In some journal issues, there was relatively high use of qualitative and multi-method approaches and up to 12% of the articles published over the past 16 years could be ...

Various construction industries, particularly developed ones, have mechanisms in place to alleviate the aforementioned risks. Moreover, it has been reported that construction organizations in developing countries, approach risk management implied risk allocation in construction projects by using a set of practices that are normally insufficient, often produce poor results, and limit the success of project outcome. It is from this background that a risk allocation mechanism tailored to the Zambian building sector is proposed, based on the RIBA plan of work for new large to medium sized projects. Various mechanisms and processes are documented in the existing literature, all developed for particular jurisdictions, project types and modes...

The literature points out that risk management is the key to ensuring that optimal risk allocation is achieved. While the focus on risk allocation has been about the party best suited to carry a given risk, the issue of how misallocation occurs is rarely dealt with. This paper modeled how risk misallocation can result from contract practice. This was done through a literature review and 15 purposive heterogeneous semi-structured interviews conducted with clients, project managers, architects, engineers and quantity surveyors in the Zambian building sector. The derived model suggests that misallocation could result from inappropriate selection of risk mitigation mechanisms provided for in the contract, poor selection of contracts and use of inappropriate procurement routes. These findings advance knowledge that necessitates the allocation of risk appropriately as the areas of contract practi...
An analysis of the allocation of pertinent risks in the Zambian building sector using Pareto analysis

Nevertheless, how favourably the contractor views the risk allocation has a bearing on the project outcome. This research identifies the pertinent risks in the Zambian context and establishes how they are allocated in terms of types of contract clauses used and response mechanisms employed. A mixed-sequential approach was followed, comprising 15 semi-structured interviews, 198 questionnaire-survey respondents and document analysis (eight projects using various standard forms of contract). The respondents comprised of clients, consultants and contractors involved on medium- to- large-scale building projects. Findings show the pertinent risks in the industry were due to shortcomings of the design team and clients’ shirking. Using a Pareto analysis, a pervasive propensity was found for passive risk acceptance and wanton risk transfer by the client. Modifications were found, aimed at negating the clients’ responsibility for risk. The originality of this research lies in its methodological approach and its focus on how risks are allocated. Findings can help practitioners to better allocate risk and promote the achievement of desired project outcomes through careful selection and utilization of mechanisms, allocation of risk and use of contract clauses.

A plethora of current studies in literature dwell overwhelmingly on risk identification much to the exclusion of the source, and the possible mitigation interventions. In a limited effort to address this deficiency in the body of knowledge, this article reports the results of a study conducted using 15 purposive semi-structured interviews and 198 questionnaires targeting clients, contractors and consultants in the building sector in Zambia. This study uses threats to identify improvement areas in the Zambian Construction Industry (ZCI). As a consequence, this research uses the pertinent risk factors as a point of critical analysis to recommend improvement areas for project risk management. Findings show that most of the risks could be categorised as managerial, technical and finance related and could severally be associated with clients, consultants, and contractors compared to project managers. These could be mitigated in the pre-contract phase and construction phase, with the most deficient knowledge areas being cost management, procurement management, integration management, communication manage ment, and scope management. This article provides areas of focus for built environ ment professionals to improve project delivery and thereby enhance project execution efficiency.
