Behavior-based safety management in Hong Kong's construction industry

A behavior-based approach to industrial safety management has been advocated by many authors and has been found to effectively improve safety performance in different industrial settings and on different continents. This paper reports on the implementation of a behavior-based safety management program in the Hong Kong construction industry. The behavior-based safety management techniques of performance measurement, participative goal setting, and the provision of performance feedback were introduced in a carefully controlled field experiment on seven public housing construction sites in Hong Kong. The paper describes this experiment and explains how the program was implemented. The results of the experiment were mixed. Behavior-based safety techniques were highly effective in bringing about improved performance in site housekeeping, but significant improvements in access to heights were only observed on two of the seven sites, and there was found to be no significant improvement in the use of bamboo scaffolding during the experimental intervention. The paper presents these results and discusses factors that may have contributed to the limited effectiveness of the techniques in the latter two performance categories.

The work-life experiences of office and site-based employees in the Australian construction industry

A survey was conducted among employees of a large Australian construction firm. Comparisons were made between employees who differed by gender and work location. Male employees in site‐based roles reported significantly higher levels of work to family conflict and emotional exhaustion than male employees who worked in the regional or head office. Site‐based male employees were also less satisfied with their pay than male respondents who worked in the regional of head office. Few significant differences were found between women who worked in different locations. Neither were significant differences between men and women who worked in the same location reported. The results are explained in terms of womens tendency to work in administrative, secretarial or support services roles, which typically demand fewer hours. The paper concludes that the experiences of site‐based construction employees, particularly men, warrant further attention to explore the sources of work‐life imbalance and burnout.

Measuring Safety Climate of a Construction Company

Safety climate can benefit contractors, specialty contractors, and owners of industries by providing them with the knowledge of attitudes and perceptions that can help to consistently achieve better safety performance. The objective of this research was to determine safety climate that would enhance safety culture and positively impact perceived safety performance on construction projects. A safety climate questionnaire survey was conducted on the construction sites of a leading construction company and its subcontractors in Hong Kong. Approximately, 1,500 hard copy questionnaires were distributed and the response rate was excellent, resulting in 1,120 valid questionnaires being collected from 22 construction projects. By means of factor analysis, two underlying safety climate factors were extracted, accounting for 43.9% of the total variance. Multiple regression analysis confirmed that these climate factors, “management commitment and employee involvement” and “inappropriate safety procedure and work pra...

Does a supportive work environment moderate the relationship between work-family conflict and burnout among construction professionals?

Research findings concerning the extent to which various forms of support in the workplace moderate the stressor‐strain relationship are inconsistent. The effect of perceived organizational support (POS) and support from supervisors and co‐workers in the relationship between work‐family conflict (WFC) and burnout was examined in a sample of 202 construction professionals and managers. The results revealed that POS has a main effect on burnout and also moderates the relationship between WFC and burnout. The effect of social support did not differ according to its source. Effects for supervisory and co‐worker support were similar. However, different effects were found for different types of support. Emotional support had a main effect on burnout but not a moderating effect in the WFC‐burnout relationship. Practical support had a moderating effect, but not a main effect on burnout. The importance of supportive work environments to the success of interventions designed to alleviate or prevent employee burnout is discussed.

Construction site safety in Hong Kong

The structural characteristics of the Hong Kong construction industry, most notably its elaborate system of subcontracting and the casual basis on which labour is employed, pose serious problems for safety managers. By international standards, Hong Kongs construction industry performs very badly in the area of safety. Recent work in the UK and Finland highlights the effectiveness of behavioural techniques to improve safety performance on construction sites. Work is currently under way to test these techniques in the Hong Kong construction setting. The structural properties of the Hong Kong construction industry have been taken into consideration and labour commitments to the group and to the organization have been identified for additional consideration in research. It is expected that these variables will intervene in the application of behavioural techniques to determine their effectiveness. This paper investigates the theoretical background to commitment at the group and organizational level and prese...

Safety climate in conditions of construction subcontracting: a multi-level analysis

A multi‐level safety climate model was tested in the Australian construction industry. Subcontracted workers’ perceptions of the organizational safety response (OSR) and supervisor safety response (SSR) in their own organization and that of the principal contractor were measured using a safety climate survey administered at a large hospital construction project in Melbourne. One hundred and fourteen construction workers completed the survey, representing nine subcontractors engaged at the project. Two requisite conditions for the existence of group‐level safety climates, i.e. (1) within‐group homogeneity; and (2) between‐group variation were satisfied for perceptions of subcontractors’ OSR and SSR. This supports the contention that subcontractors working in a single construction project exhibit a unique group‐level safety climate. Subcontracted workers also discriminated between group‐level safety climates (i.e. the SSR) in their own and in the principal contractor’s organizations. The results suggest some cross‐level influence. Perceptions of the SSR were positively predicted by perceptions of the OSR in both the principal and subcontractor organizations. Perceptions of the OSR of the principal contractor were also a significant predictor of the perceived OSR and SSR in the subcontractor organizations. Perceptions of the subcontractors’ SSR were a significant predictor of the rate of lost‐time and medical treatment incidents reported by the subcontractor. Although perceptions of the principal contractor’s SSR were not directly related to subcontractors’ injury rates, they were a significant predictor of subcontractors’ SSR, revealing an indirect link. The results suggest that supervisory personnel (e.g. foremen and leading hands) play an important role in shaping safety performance in subcontracted workgroups.

Behaviour-based safety management in Hong Kong's construction industry: the results of a field study

Hong Kongs construction industry has had a poor site safety record for over a decade. Behaviour-based methods of safety management (BSM) have proved successful in other industries and in other countries. Hence, this study aimed to test the effectiveness of BSM by applying goal-setting and feedback interventions to specific areas of safety performance on Hong Kong Housing Authority construction sites. Using a within-group experimental design and with the use of a proportional rating safety measurement instrument, data were collected on the effectiveness of BSM on Hong Kong sites. The data were recognized as time series data; this has been a serious methodological oversight in much previous research. The data were analysed using autoregressive moving averages models, and the results were mixed in that a significant improvement in safety performance occurred in the housekeeping category of intervention but no improvement was observed in the access to heights and bamboo scaffolding categories. Based on these results a goal setting/expectancy theory model of site safety improvement has been synthesized, and the lack of provision of an adequate safety infrastructure has been identified as a serious impediment to improvement.

ToolSHeD™: The development and evaluation of a decision support tool for health and safety in construction design

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.

Group-level safety climate in the Australian construction industry: within-group homogeneity and between-group differences in road construction and maintenance

In modern organizations it is overly simplistic to assume that a uniform, organization‐wide climate for safety develops. Workgroup‐level safety climates are more likely to arise in decentralized organizations and their influence on occupational health and safety (OHS) behaviour is likely to be stronger when work is non‐routine, as in construction. The existence of workgroup‐level safety climates was examined in the Australian construction industry. A group‐level safety climate survey was conducted in a road maintenance and construction organization. The clear factorial structure produced in a larger sample of Australian defence logistics workers was not replicated and factors splintered, possibly due to the subject‐to‐item ratio in the construction study. However, the internal reliability consistency of the factors produced in the earlier pilot study was found to be acceptable for the construction industry data. Two requisite conditions for the existence of group‐level safety climates, i.e. (1) within‐group homogeneity; and (2) between‐group variation, were satisfied within the road construction and maintenance organization. The results indicate that distinct workgroup safety climates exist in construction, providing a theoretical explanation for why some workgroups perform better in OHS than others, despite having similar risk exposure.

Improving solid waste reduction and recycling performance using goal setting and feedback

A multiple-baseline experiment design across waste streams was used to determine the effectiveness of a goal setting and feedback intervention in bringing about improved solid waste management performance on a sports stadium construction site in Australia. A desktop method was used to measure the volume of timber and construction waste disposed as landfill and recycled. A general index of material usage efficiency and two recycling indices were calculated. Performance was measured each fortnight and formal goal setting and performance feedback were introduced to the timber and concrete waste streams. The intervention was effective in reducing the volume of waste disposed as landfill and increasing material usage efficiency, indicating that solid waste was reduced at source or re-used. Recycling performance did not improve significantly with the introduction of the intervention. This may be due to the way in which construction workers perceive the costs and benefits of recycling.
