- Description: Abstract: This paper discusses the Delphi method which is an inductive approach to research. It has been argued that Delphi method is an essential vehicle of reaching consensus in issues that cannot be resolved in a once off discussion. This paper reports on the experiences achieved by the authors in using the Delphi method among a group of experienced health and safety (H&S) experts in two separate case studies in the construction industry in South Africa. The first case study used three rounds of iteration whilst the second case study used four rounds of iteration. The authors argue that the Delphi method is a comprehensive method of attaining consensus on challenging issues of H&S in the construction industry. Furthermore the method requires proper communication to achieve the required results.

- Description: This study sought to identify and validate a comprehensive set of health and safety (H&S) leading indicator metrics that will enable small and medium construction enterprises (SMEs) personnel to monitor the level of H&S performance in their projects. The Delphi approach was used where the opinion of H&S experts, academics and industry practitioners were canvassed on 64 potential indicator metrics, categorized in 10 elements or leading indicators that will enable H&S performance improvement e.g. reduction in accidents, injuries, diseases but to name a few. The experts rated each indicator metric on a 10-point Likert scale of impact, where 1= no major impact or 10% impact and 10 = major impact or 100% impact. Consensus was reached on 32 indicator metrics after four successive rounds of Delphi if the indicators attracted final scores of, percentage median impact of 90% to 100% which is 9.00 to 10.00 median rating and over 50% of respondents rating the indicator metrics in the band of 9.00 to 10.00 or 90% to 100% impact to improve H&S performance. The experts had the opportunity to reconsider their scores informed by the group median score in rounds 2, 3 and 4. The limitation of the study was the reliance of a structured questionnaire in the first round as experts were not allowed to add any new indicators, until the fourth round. This study contributes to the H&S body of knowledge where no consensus has been reached pertaining to the indicator metrics that have major impact to improve H&S performance at project level of construction SMEs in South Africa.

- Description: Abstract: The South African Mine Health and Safety Act (MHSA) requires the mine surveyor to inform the manager of all workings within 100 metres of other workings, abandoned areas and hazardous accumulations of water or gas. The main purpose of this requirement is to ensure that all employees are aware and can take all the necessary precautions against un‐planned breakthroughs, falls of ground and subsidence. In the case where mines are mining through abandoned workings in order to remove remnant pillars and previously unmined reserves, the potential for subsidence and equipment falling into excavated areas become a reality. A single incident where a machine falls into a collapsed working can amount to in excess of R1 million per incident, excluding the risk of loss of life or serious injury. An unplanned collapse of workings in the specific case study can also lead to sufficient air flow into the old underground to cause spontaneous combustion of the remaining pillars. Although systems for navigation of drill rigs exist the cost to deploy a similar unit to all vehicles in the mining area is prohibitive. A low‐cost system that can navigate a vehicle and indicate to the operator what the subsurface features look like in the direct surroundings of the vehicle was developed using off‐the‐shelf technologies. This paper discusses the process of developing a lowcost navigation system towards a real time information management system for a mining operation. Benefits from this system may be applied in underground navigation and guiding rescue services in the search of illegal miners in abandoned mines.

- Description: Abstract: The purpose of this article is to present findings of a preliminary survey on Contractors’ perceptions of clients’ attitude relative to health and safety (H&S) implementation in Botswana’s construction industry and in a way that of the Southern Africa. A questionnaire survey was conducted on construction projects to establish clients’ attitude towards H&S. Interviews were also conducted with contractor’s representatives on selected construction sites in and around Gaborone, Botswana. Findings from the survey include: clients do not perceive H&S to be very important on construction projects, most clients do not address H&S adequately in contract documentation and H&S is rarely a major agenda item in progress meetings. Findings were also that clients are not fully committed to H&S implementation. The client sets the tone for H&S culture. Client attitude is therefore very important for H&S performance improvement as all stakeholders are compelled to act in line with the client’s values. The importance of the client to H&S performance improvement has been recognised by various researchers. The extent to which clients are involved in H&S implementation has however not been researched extensively especially in Southern Africa. This article therefore provides an insight into the clients’ attitude towards H&S and in a way explains the reason for the current state of H&S in Botswana’s construction industry.

- Description: Purpose: This paper presents a review of previous studies on the subject of H&S culture and outline key H&S culture factors that are necessary to make the concept useful in the construction industry. A conceptualised model LIP+3C is also presented as the outcome of the review Design/methodology/approach: Literature review focused on exploring the conceptual definitions of H&S culture was conducted. A matrix for the identified literature was developed to identify common H&S culture elements. Findings: It was revealed that there is still confusion and lack of consensus on the concept of H&S culture. However, the H&S culture elements of leadership, involvement, procedures, communication, competence and commitment dominate the literature. Research limitations/implications: Literature review was conducted on 15 published peer reviewed journal articles. The validation of the elements found in the study is currently under way although preliminary results confirm the findings. Practical implications: H&S culture has been identified as being of great importance to H&S performance improvement. Identifying culture elements that can easily be implemented and understood will contribute to improving the current H&S status. Originality/value: Adopting the LIP+3C culture model composed of elements that can easily be implemented and understood will contribute to improving the current H&S status

- Description: Abstract: Many accidents and a general poor health and safety performance for both the construction industry and other high reliability industries have been blamed on the poor health and safety (H&S) culture that was prevalent at the time. Addressing H&S culture is therefore a very important step to eliminating accidents and thereby improve the general H&S performance within an organisation or industry. The current paper will therefore report on findings from an empirical study on improving H&S performance in a construction project and will also present a guide of how to improve the construction client’s H&S culture. The research conducted in South Africa and Botswana and whose results were modelled using structural equation modelling, found that with a better H&S culture, clients had a positive influence on H&S performance of construction projects. The client H&S culture was characterized by leadership, involvement, procedures, commitment, communication and competence (LIP+3C). A positive manifest of these factors in the client entity entailed a better H&S performance at project level. This paper will therefore present a guide on how construction clients may improve their H&S culture and thereby impact positively on project’s H&S performance. Further, the guide will exemplify how the concept of H&S culture may be operationalised in order to benefit from a concept that has been mooted as the panacea for the H&S problem in the construction industry as well as the concept that has been at the centre of major industrial disasters.

Impact significance of construction clients on designers’ and contractors’ health and safety culture- An exploratory Delphi study. Proceedings of the CIB W99 International conference on Construction health and safety, Washington DC, USA, 24-26 August 2011
- Description: Designers and Contractors’ top management have been identified in many studies to be of great importance to health and safety performance and its continual improvement. Therefore developing strategies that support and motivate designers and contractor top management to implement health and safety elements would ensure a gradual and sustained improvement of health and safety in the construction industry. In order to determine the impact significance of clients/owners on designers and contractor top management, a Delphi study was conducted. Findings from the study where that client culture has critical impact significance on designers and contractors’ top management culture. Further findings were that implementation of health and safety elements by designers and contractors were ‘very likely to occur’ with clients influence. This paper reports on findings from an analysis of impact significance of clients on designers and contractors. It will underscore the point that has been made before using different methodologies that client health and safety culture is critical to designers and contractors’ health and safety culture. The paper argues that an improved client health and safety culture will result in an improved health safety culture of designers and contractors. Pursuing this strategy can result in prevention of many accidents and incidents

- Description: Purpose: This paper presents a conceptual six factor client H&S culture model referred to as the LIP+3C. The factors leadership, involvement, procedures, commitment, communication and competence were theorised to explain the client H&S culture construct. The postulated model is based on theory obtained from literature as well as from a Delphi research. H&S culture has been recognised as the feasible way to improve H&S performance in the construction industry. Design/methodology/approach: A Delphi study as well as a synthesis of literature was conducted and resulted in a theorised conceptual model. To validate the model, a questionnaire survey with a response of 281 was conducted. Findings from the questionnaire survey were analysed using Structural Equation Modelling (SEM) with EQS version 6.1 software. Findings: The six factor client H&S culture model was found to be well fitting to the sample data through the confirmatory factor analysis. Consequently client H&S culture findings were that client culture could be explained by the level of leadership, involvement, procedures, commitment, communication and competence. Research limitations/implications: The size of the sample may affect the generalisability the findings in view of the complexity of the model. Practical implications: The proposed model in this study makes it possible to determine and predict the client H&S culture. The indicator variables can be used as check items for performance measurement and thus operationalize the concept of H&S culture. Originality/value: Adopting the LIP+3C culture model composed of elements that can easily be implemented and understood will contribute to improving the current H&S status

SMEs differ significantly from large firms, and these factors affect their compliance level. The study aims to assess the SMEs contractors Health and Safety (H&S) performance in the construction industry. Delphi survey was used for the study. Experts were asked to rate the impact of other factors in predicting SMEs contractors compliance with H&S regulations in Ghana. The rating were based on either the impact was considered to be very high or high. Microsoft EXCEL to analyse the data collected. The output from the analysis was a set of descriptive statistics such as means, median, standard deviations and derivatives of these statistics. The findings from the study shows that changes in company structure, changes in ownership at various stages of growth, lack of H&S experts and short track records of H&S regulations were rated by the experts among the factors that affect the SMEs contractors H&S performance.
