Competency-based measure is increasingly evident as an effective approach to tailoring training and development for organisational change and development. With design stage widely reckoned as being decisive for construction waste minimisation, the purpose of this paper is to identify designers’ competencies for designing out waste.

Due to paucity of research into competency for construction waste mitigation, this study corroborates verbal protocol analyses (VPA) with phenomenological research.

Combining findings from the two methodological approaches, competencies for designing out waste are grouped into five categories, three of which are largely task related and two being contextual competencies. The study suggests that design task proficiency, low waste design skills and construction-related knowledge are indispensable task competencies, while behavioural competence and inter-professional collaborative abilities are requisite contextual competencies for designing out waste. In concurrence with task-contextual theory of job performance, personality variables and cognitive abilities are found to influence one another. This suggests that both task and contextual competencies are not only important, they are less mutually exclusive with respect to designing out waste.

This study implies that apart from commitment and dedication of designers to waste minimisation, design and firm practices are expected to be adapted to the industry’s standard.

Basis for training needs of design professionals as well as redeployment criterion are further elaborated in the paper. By enhancing competencies identified in this study, construction waste would not only be significantly designed out, adequate cost saving could be made as a result of waste reduction.

The purpose of this paper is to synthesize and evaluate the available literature with respect to critical success factors (CSFs) for sustainable construction (SC).

A systematic literature review (SLR) was undertaken to assist in the identification of the most pertinent papers from three publishers: Emerald, Elsevier and Wiley. The literature findings were assessed and presented relative to publication, author and contents as determined by review.

The SLR was conducted using a number of search criteria. A final set of 31 publications were detected for further examination. The characteristics in terms of publications, authors and contents of the extracted publication set were examined and discussed. A total of 35 factors were identified, distributed in five research categories. The frequency of the extracted factors within the publication set was investigated and enabled valuable quantitative and qualitative observations of current trends for SC. Interestingly, all research categories were represented in the top-counted factors, demonstrating a holistic perception of SC. Given the publication set, in most aspects, the research area examined seems to demonstrate features of an emerging field, which is not yet well established.

SLR cannot ensure that all pertinent publications were identified, because it was tailored to a number of search criteria, although certain actions were taken to moderate this limitation. However, the outcome adequately identifies trends and offers valuable information and knowledge for SC and its successful implementation.

The present study presents a broad list of factors for SC, integrated from a variety of disciplines and stakeholders. The findings, therefore, provide a valuable reference for both construction professionals and practitioners attempting to implement SC. Furthermore, the list can be of use to academic scholars for further empirical work and basis for future research.

There have been speculations as to whether environmental friendly buildings are always healthy. Using lifecycle assessment (LCA) methodology, the purpose of this paper is to investigate lifecycle relationship between building sustainability and its environmental health impacts

In order to achieve this, a block of classroom was modelled with the aid of Revit software, and its lifecycle global warming potential (GWP) and human health impacts were analysed using green building studio and ATHENA impact estimator tools. Sensitivity analyses of the block of classrooms were then carried out by varying the building materials and energy use pattern of the original typology. The LCA was performed for seven alternative typologies that were achieved through variation in the building materials and energy use patterns.

For all the eight building typologies, the study shows a direct relationship between GWPs and human health impacts. This confirms that the more sustainable a building, the less its tendency for having negative health effects on building operatives, occupants and the wider environment. Again, the more green a building in terms of its materials and energy use pattern, the healthier the building becomes.

The human health impacts was evaluated by measuring amount of particulate matter (PM2.5) produced by the buildings while environmental impact was evaluated by measuring global warming (KgCO₂) potentials of the buildings throughout its lifecycle. The study has been based on the impacts of building materials and energy use patterns over the entire lifecycle of the buildings and materials used for construction.

The study established a positive relationship between GWP of building and its human health impacts. Thus, all arguments relating to the relationship between building sustainability and health are laid to rest by the paper.

The past decade has witnessed a tremendous and progressive growth in the number of Nigerians who engage in medical tourism from Nigeria to India. Various commentators have advanced diverse reasons for this trend. However, there is a dearth of research that has sought to provide empirical insights. This paper aims to investigate the decision-making process of Nigerian medical tourists and why they prefer medical tourism to India to medical care locally.

Eight Nigerian medical tourists are interviewed on a one-on-one basis with open-ended questions using purposive criterion sampling technique from an interpretivist mind-set.

The paper identifies two major motivators, namely, inadequate medical infrastructure and poor medical, and customer service from health workers in Nigeria, which spurred medical tourism from Nigeria to India. Further, it finds that first timers premise their decisions on advice from reference groups, while previous personal experiences guide decisions on subsequent medical travels. Findings are explained using the template provided by the theory of planned behaviour.

This exploratory nature of this research provides a useful basis to elucidate the course of decision-making of Nigerian patients so that appropriate marketing communication channels can be applied. It improves the process of recruiting and engaging Nigerian patients and nurturing wholesome relationships between Nigerian patients and hospitals.
