Description:
An important principle of Australian OHS law is that workers participate in the management of health and safety via OHS committees and representatives. A further principle is that workplaces engage in problem solving processes according to a hierarchy of hazard control - rather than simply following prescriptive rules. The OHS committee is therefore a problem-solving forum. However, the benefits of problem- solving or creative thinking techniques within committees have not been widely explored. To test the effects, two OHS committees from two construction companies were trained in a combination of creative thinking and risk control concepts. Subjects were tested on their ability to generate solutions and to rank solutions. They were compared with untrained subjects from two further committees. The results showed that the trained subjects generated more solutions and, when ranking solutions, showed a greater preference for solutions which were higher on the hierarchy of controls.

Although there are few sources of information specific to plastering, there are data that suggest that individuals who do this type of work are at high risk of injury. While it is commonly accepted internationally that plasterers are exposed to significant risks in the areas of manual handling and falls, direct comparisons to and wholesale adoption of overseas knowledge are inappropriate. A literature review has demonstrated that there has been a great emphasis on defining the size of the problem. There is limited research relating to the adoption of evaluated risk control strategies, and what controls are known are not necessarily universally applicable. The risk control strategies that are known and available are in need of evaluation. To increase the adoption of evaluated risk controls, it is recommended that social marketing strategies be used.

Purpose - The purpose of this paper is to describe an innovative information and decision support tool (ToolSHeD™) developed to help construction designers to integrate the management of OHS risk into the design process. The underlying structure of the prototype web-based system and the process of knowledge acquisition and modelling are described. Design/methodology/approach - The ToolSHeD™ research and development project involved the capture of expert reasoning regarding design impacts upon occupational health and safety (OHS) risk. This knowledge was structured using an innovative method well-suited to modelling knowledge in the context of uncertainty and discretionary decision-making. Example "argument trees" are presented, representing the reasoning used by a panel of experts to assess the risk of falling from height during roof maintenance work, The advantage of using this method for modelling OHS knowledge, compared to the use of simplistic rules, is discussed Findings - The ToolSHeD™ prototype'development and testing reveals that argument trees can represent design safety risk knowledge effectively. Practical implications - The translation of argument trees into a web-based decision support tool is described and the potential impact of this tool in providing construction designers (architects and engineers) with easy and inexpensive access to expert OHS knowledge is discussed. Originality/value - The paper describes a new computer application, currently undergoing testing in the Australian building and construction industry. Its originality lies in the fact that ToolSHeD™ deploys argument trees to represent expert OHS reasoning, overcoming inherent limitations in rule-based expert systems.

"Small businesses are regularly perceived to be poor performers in OHS management. However, attributing poor performance soley to size, to the hazardous nature of the industry or to a simplistic combination of both aspects neglects the recognition that there are some small businesses that can manage OHS with greater capacity than others."

Description:
Consultation is generally acknowledged both in Australia and internationally, as being essential if high levels of occupational health and safety (OHS) are to be achieved and maintained. In Victoria, such is the recognition of the important role that consultation plays in OHS, that it is mandated under the Victorian OHS regulatory framework. Indeed, all Australian OHS statutes now make provision, to varying degrees, for consultation to occur when dealing with OHS matters. This is principally conducted through OHS representatives and OHS committees. However, there is a growing body of opinion which raises concerns over whether such legislative provisions that provide for OHS consultation, is sufficiently adequate to ensure that the consultation is both meaningful and effective in terms of OHS outcomes. If this is the case, what might be missing or lacking from the consultation process, especially in hazardous and dangerous industries where OHS success would appear to be imperative? The Victorian construction industry, like the construction industry in general, is acknowledged for its dangerous and hazardous nature. It has a large transitory workforce with little permanent job security and often suffers from a multifarious and disjointed work organisation structure. Such features tend to work against an environment that openly recognises and encourages meaningful and effective consultation. These conditions also tend to confound the development of any kind of social and positive learning and communicative culture within the industry, leading to an underutilization of the knowledge and skill contained within the workforce. As well as failing to bring to fruition the full participation of workers in the management of OHS, the underutilization of knowledge and skill is potentially one of the largest hidden costs that an organisation may incur. The notion of organisational and cultural maturity is acknowledged both internationally and in Australia as a useful concept that can assist organisations in achieving higher standards and levels of OHS. This is especially so in high risk and hazardous industries such as the petrochemical, oil refinery and aviation industries. However, organisational and cultural maturity is arguably a relatively new and under-researched construct in the Victorian building and construction industry, while the concept of consultation within both the industry and the organisational maturity paradigm has not yet been sufficiently explored. The role that moral and ethical principles play in consultation is now beginning to emerge and gain wider recognition within the literature. This research project set out to examine how some of these principles were applied by senior site managers and OHS representatives of five Victorian construction companies during OHS consultation at five different constructions sites, and whether this consultation could be considered to be meaningful and effective. The companies who participated in this project were each allocated a level of organisational maturity, dependent upon how they managed various aspects of their business operations in terms of OHS. Senior managers and OHS representatives were chosen as participants in the research because they are generally acknowledged as the critical vectors in the sharing and transferring of knowledge and skill at the workplace. The data from this research suggest that regardless of the level of organisational maturity each organisation was deemed to have reached, and no matter how the individual participants applied the particular moral and ethical principles used during this research, the OHS consultation that took place on the different construction sites was limited to, and focused primarily on, everyday operational and execution aspects of the job, rather than more strategic and longer term OHS issues. The practical implications of this research are that if OHS consultation between senior managers and OHS representatives can be conducted in such a way as to openly and unambiguously recognise and apply particular moral and ethical principles, and if consultation is allowed to focus on more strategic and longer term OHS and organisational aspects of a construction project, this may yield more benefits, in terms of OHS outcomes, for all industry participants.

Employee perception on causes and forms of conflict in the Botswana contruction industry : A comparative study between domestic-owned and Chinese-owned companies
Description:
The construction industry in Botswana plays a crucial role in the economic development of the nation. While much research in this sector centres on the technical issues, especially the tender/procurement processes as they have evolved over the years, there is limited research on employment relations. This study investigates the lived experiences of employees in the Botswana construction industry in both domestic-owned and Chinese-owned companies and aims to capture „snapshots‟ of their perceptions of the causes and forms of conflict within that sector. Adopting a pragmatism research paradigm, this research employs a mixed methods research protocol to obtain quantitative and qualitative data from a sample of 632 employees. The overall results reveal that there are statistically significant differences between domestic- and Chinese-owned companies, with respect to how employees perceive income distribution, job security and managerial control as causes of conflict. The empirical results show that there is a positive relationship between employees‟ negative workplace perceptions and various forms of workplace deviant behaviours that employees use to retaliate in the event they perceive some form of unfairness, particularly in wages, job security or how managers/supervisors treat them. In domestic-owned companies there is a significant and positive association between disparity of income distribution and personal gain deviant behaviours such as theft as compared to other deviant activities against the production process including sabotage and production deviance; while in Chinese-owned companies there is a significant positive association between all forms of workplace inequities (income distribution, job security, managerial control) and all forms of conflict. This study contributes to the development of a more rigorous approach to the analysis of industrial relations conflicts in the construction industry in developing economies. This type of comparative research between domestic- and Chinese-owned companies could possibly be transferred to similar industries, such as in manufacturing and retail, where there are also a significant number of foreign-owned companies. This thesis concludes by discussing the various contributions made by this study to both academia and practitioners. It also details several recommendations for future research and for ensuring peaceful and productive employee-employer relationships in the workplace.

Description:
The heavy construction industry, as a contractor-dominated environment, is challenged by the need to achieve significant and sustainable improvements in occupational health and safety performance. To overcome such challenges an occupational health and safety improvement methodology was developed incorporating a transformational change model and an action research method."
Description:
The construction sector continues to play a significant role in the socio-economic development of many nations, most importantly, today’s emerging economies. Although the sector is labour intensive and employees play critical roles in various projects and their success, there has been little research on people management practices and policies. Obtaining data from 617 employees working in eight Botswana construction companies, this study investigates employees’ perceptions of job insecurity and conflict in domestic-owned and Chinese-owned companies. The results show that there is a significant positive relationship between temporary work and perception of job insecurity and as such, job insecurity is positively related to conflict; these have large and significant impacts on deviant workplace behaviour. Also, there is statistically significant difference between males and females in both types of companies on how they perceive job insecurity as the cause of conflict, which needs to be addressed in human resource management to ensure better labour relations and higher labour productivity.
Description:
Concrete is the most commonly used construction material because of its various advantages, such as versatility, familiarity, strength, and durability, and it will continue to be in demand far into the future. However, with today’s sensitivity to environmental protection, this material faces unprecedented challenges because of its high greenhouse gas emissions, mainly during cement production. This paper investigates one of the promising cement replacement materials, alkali-activated cement (AAC) concrete. Being produced mainly from byproduct materials and having a comparable structural performance to conventional concrete, AAC concrete can transform the construction industry. Mechanical properties such as compressive and flexural strength and the relationship between them are studied. Different source materials such as fly ash (FA), ground granulated blast furnace slag (GGBS), silica fume (SF), and Metakaolin (MK) are used. The effect of the source materials and the activator solutions on the concrete performance is studied. Furthermore, the freeze-thaw resistance of the concrete is studied. The study results showed that the behavior of AAC depends highly on the source material combinations and type used. The effect of the alkaline solution is also dependent on the source material used. Mixes with higher GGBS content showed the highest strength, while mixes with MK showed the highest flexural strength. The freeze-thaw test results showed that proper design of AAC concrete with lower water content is critical to achieving a good resistance.
