Safety Management in Construction: Best Practices in Hong Kong

Safety issues have gained vital importance throughout the construction industry. Many construction companies around the world are implementing safety, health, and environmental management systems to reduce injuries, eliminate illness, and to provide a safe work environment in their construction sites. This paper describes an exploratory study of site safety management in construction sites’ environments. It explains a successful, modern safety, health and environmental management system for a leading construction company based in Hong Kong. A typical site-specific safety plan was utilized to provide safety guidance throughout the construction project. A safety management survey was conducted to determine the status of safety in the construction sites. All employees of the company and its subcontractors participated in the survey from 20 construction projects. In total, 1,022 valid records were obtained from the construction sites. The analysis provided useful information on eight aspects of construction safety, including safety policy and standards, safety organization, safety training, inspecting hazardous conditions, personal protection program, plant and equipment, safety promotion, and management behavior. The findings of the survey provide practical knowledge to construction project managers and construction safety practitioners in order to make their sites safer. Insights and discussions are given in this paper.     

Chinese Values and Stressors of Construction Professionals in Hong Kong

The construction industry has been recognized as a stressful industry, and a great deal of stress is placed on various construction professionals (CPs). However, due to the different “values” among CPs in Hong Kong, susceptibility to stressors varies from individual to individual. People who grow up and live in different cultural environments have different values and this leads to different perceptions of stressors. This study aims to investigate the impact of Chinese values on the stressors of CPs in Hong Kong, one of the main cities in China. To achieve this aim, factor analysis, Pearson correlation analysis, and structural equation modeling were applied based on the survey data collected from CPs in Hong Kong. Four types of Chinese values and eight stressors are identified. The results reveal that: (1) social conventions value alleviate role ambiguity and poor workgroup relationship; (2) value of disciplined work ethos triggers work overload, although it alleviate poor workgroup relationship and work underload; (3) value of conservative personality alleviates work overload; (4) interpersonal integration value has indirect impacts on the various stressors; and (5) the objective poor working environment stressor has significant impact on the poor workgroup relationships and role ambiguity of individual CPs.     

Integrated Model for the Stressors and Stresses of Construction Project Managers in Hong Kong

Construction projects involve multistakeholders (e.g., architects, structural engineers, surveyors, contractors, suppliers, etc.) completing a large number of unpredictable tasks in a complex process within a limited period of time. Construction project managers (C-PMs) are the key persons in achieving project success throughout the construction process, as they are responsible for planning the construction program, organizing human resources, controlling operations and the budget, and forecasting probable difficulties. Hence, C-PMs always encounter a great deal of stress in construction projects. Apart from the subjective feelings experienced by individual C-PMs, C-PMs may also feel objective stress due to the deviation between their actual abilities and their expected abilities on tasks or projects. To understand the integrated relationships between the various stressors and stresses of C-PMs, a survey was conducted of 108 C-PMs in Hong Kong. This paper attempts to investigate the causal relationships between stressors and stresses (both subjective and objective). The study reveals seven stressors of C-PMs in the industry. Based on the results of a correlation coefficient, an optimized stressor–stress structural equation model is established. Four critical stressors were found to have significant impact on both the subjective and the objective stresses of C-PMs, including work overload, poor interpersonal relationships, poor work environment, and poor nonwork environment. A number of recommendations were made for both construction companies and individual C-PMs in their offices and at home in order to optimize their work performance in the real world.     

Adjudication: Temporary Binding and Tiered Dispute Resolution in Construction and Engineering: Hong Kong Experience

Hong Kong (under the “One Country Two Systems” Policy, Hong Kong, although an administrative region of the PRC operates a separate legal system, whose roots lie in the English common law system) has a justified reputation for being at the forefront of developments in techniques to avoid and resolve disputes in the construction industry. [This is illustrated by the adoption of the UNITRCAL Model Law by the Arbitration (Amendment) Ordinance 1996, specific powers given to Arbitral Tribunals under the Arbitration Ordinance (Cap. 341) including powers to consolidate, and the development of the dispute resolution adviser system. See the genesis, development and future use of the dispute resolution adviser system by Colin J Wall, Hong Kong Society of Construction Law dated November 17, 2004]. However, it has not, to date, seen the widespread adoption of adjudication as a means of resolving disputes. This article examines the history of the use of adjudication in Hong Kong, current trends, and offers some possible reasons for the limited adoption of adjudication.     

Construction Mediation Landscape in the Civil Justice System in Hong Kong

Alternative dispute resolution techniques as means to speedily and economically resolve certain types of disputes have been well recognized. In this regard, some jurisdictions have opted to use mandatory adjudication to deal with construction, in particular payment-related disputes. The situation in Hong Kong is a bit different. The Government of the Hong Kong Special Administrative Region aspires to make Hong Kong a hub for arbitration and mediation services for the region. Voluntary mediation has been introduced in the civil procedures rules of the High Court as part of the newly launched Civil Justice Reform. Adverse cost order is used to discourage “refusal to mediate” and “failing to attempt to mediate.” While the new measures that came into effect on April 2, 2009, sound sensible, a better picture on the actual impacts will unfold as more cases reach the Court. Nonetheless, the cost sanction may be able to make the voluntary use of mediation less voluntary.     

Analysis of Construction Worker Injuries That Do Not Result in Lost Time

Attempts to examine the root causes of injuries in the construction industry have been largely focused on fatalities and other serious injuries. These efforts were undertaken with the assumption that the root causes of serious injuries could lead to identifying approaches that could prevent the recurrence of similar injuries in the future and that these approaches would also be successful in eliminating many minor injuries. While some injuries may be either minor or serious depending on small differences in worker position, etc., that assumption does not appear to be valid for most injuries. The trends of causes leading to minor injuries are often quite different from those resulting in serious injuries. With this assumption, an examination was conducted to profile nearly 136,000 construction worker injuries, most of which did not result in lost time. Results indicate that these injuries, not resulting in lost time, generally do not fit the profile of injuries that result in fatalities or that are serious. Over half of the injuries in the present study were associated with lacerations (usually of the fingers and hand) and injuries sustained by the lumbar spine, upper extremities, or eyes. The percentage of injuries that involved lacerations was considerably higher for construction than for all other industries. The costs of injuries were found to be quite varied, depending on the part of the body that was injured.     

Construction in Hong Kong: Success Factors for ISO9000 Implementation

This paper examines the success factors for the implementation of ISO9000 in the Hong Kong construction industry. The critical factors for construction contractors to successfully implement ISO9000 were identified. An analytic hierarchy process model was then developed to determine the relative importance among those factors. The findings showed that the top management commitment is the most critical factor for the successful ISO9000 implementation, whilst the common goal, teamworking, education and training, and the cultural changes are also the important factors.     

Insight into Resolving Construction Disputes by Mediation/Adjudication in Hong Kong

Resolving construction disputes using an adversarial approach is considered to be in opposition of the maintenance of a harmonious relationship between two parties. The modern arbitration process may emulate the litigation proceeding leading to delay and cost escalation. During the past decade, the Hong Kong Government has implemented a mediation clause as an alternative mode for settlement of construction disputes. In this paper, the experience and insight into resolving construction disputes by integrating mediation and then arbitration in Hong Kong are highlighted. The state-of-the-art modern mediation process and its philosophical origins are reviewed. The shortcomings of the present system are pinpointed. The success of the adjudication now practiced in the United Kingdom may suggest that there is a place for another process of dispute resolution, which may help improve the situation. The prospect of the proposed mediation/adjudication and then arbitration mechanism is discussed with particular reference to the construction industry in Hong Kong.     

Comparative Injury and Fatality Risk Analysis of Building Trades

Occupational injury and fatality risk analysis was performed on 16 building trades in the study reported herein. The approach was based on defining risk fundamentally as the product of probability (frequency) and severity, and using the risk plane concept to evaluate and rank the trades in terms of nonfatal injury rates. A parameter named index of relative risk was then used for fatality rate based ranking, and the results separately obtained from these analyses were integrated into a combined risk score for arriving at final rankings. Bureau of Labor Statistics data was used in the study. The risk analysis methodology included both frequency and severity considerations associated with nonfatal injuries. It was observed that simultaneous consideration of frequency and severity gives more comprehensive results than performing risk analysis based exclusively on either frequency or severity. The findings of the study indicated that ironworkers and roofers were the highest risk trades. The information derived from the methodology presented in this paper should be particularly valuable for risk managers, legal and liability experts, and project managers.     

Psychosocial Factors and Musculoskeletal Disorders in the Construction Industry

Musculoskeletal disorders (MSDs) constitute more than half of the total injuries and illnesses within the construction industry. The aim of this study was to assess the prevalence of MSD among construction workers and identify the psychosocial and physical risk factors associated with their occurrence using an on-site survey instrument. One hundred forty seven construction workers (representing three trades) participated in the study. The 1-year prevalence of MSD was high with 61.2% reporting severe symptoms and 39.7% having some functional impairment due to MSD. Physical task requirement was the most important factor associated with MSD reflecting the physical nature of construction work. Economic and performance factors were the most stressful psychosocial factors reported and significantly increased the risk of reporting MSD. The findings of this research underscore the independent role that psychosocial factors play in the health and safety of construction workers. Understanding this role is imperative for practitioners and academics alike in the quest to make construction a safer work environment for all workers.     

Safety Climate in Construction Industry: A Case Study in Hong Kong

Because of the characteristics of decentralization and mobility in the construction industry, safety culture is crucially important. A comprehensive safety climate questionnaire survey was conducted with all sites and employees of a leading construction company and its subcontractors in Hong Kong. In total, 4,719 records were returned from 54 sites. By means of factor analysis, a 15-factor structure that defines the dimensions of the safety climate has been extracted. Compared with previous research studies, the roles and influences of fellow workers, and safety resources on the safety climate are emphasized. The results also confirm the feasibility of exploring common factors of the safety climate in the construction industry. Through further analysis, logistic regression was used to explore the relationship between the safety climate and personal characteristics. Statistically significant relationships were found between safety climate and personal characteristics, including gender, marital status, education level, number of family members to support, safety knowledge, drinking habits, direct employer, and individual safety behavior. This research is a case study and the results are derived from the data of one company, but the methodology of this research may be useful as a model for further research, and the findings may provide useful information for construction managers and safety practitioners in the construction industry to improve their safety culture.     

Interlocutory Injunctions in Construction Cases in Hong Kong: Revisiting American Cyanamid Principles

Interlocutory injunctions in construction litigation cases are not uncommon, in particular, in construction nuisance cases. Despite its importance, there are only a few written materials dealing with this topic. With the public increasingly aware of their legal rights, it is anticipated that the number of interlocutory injunction applications will remain high in the foreseeable future. It is now timely and a worthwhile exercise to revisit those principles governing the courts’ discretion in granting and rejecting interlocutory injunctions. This paper discusses those factors that are relevant in exercising that discretion and how they should be assessed. It also examines the principles established by Lord Diplock in the landmark case “American Cyanamid,” i.e., how this case influenced judgments in recent Hong Kong construction cases. The paper concludes by summarizing the overriding principles in interlocutory injunction applications.     

Modeling Construction Occupational Demand: Case of Hong Kong

Appropriate training can only be developed if training needs for specific skills are carefully identified. This paper, further to an aggregate model developed previously, aims to forecast the occupational share of the aggregate manpower demand for the construction industry of Hong Kong. The forecast, based on existing manpower statistics, is divided into two levels: broad occupations and detailed occupations. The broad occupational demand forecasting model is formulated using a time-series regression analysis to derive the relationship between the occupational share and the construction output cycle, technology, and various work-mix variables; whereas exponential smoothing technique is used to forecast the share of detailed occupations. This occupational demand estimation can provide solid information to facilitate manpower planning. It enables the policymakers to foresee the trends of occupational manpower demand and formulate policies and training and retraining programs tailored to deal effectively with the industry’s human resource requirements in this critical sector of the economy. Although the study focuses on developing models for the Hong Kong construction labor market, the adopted methodology can be applied in other labor markets to develop such models for manpower planning.     

Physical Risk Factors and Controls for Musculoskeletal Disorders in Construction Trades

Adoption of the Washington State Ergonomics Rule in 2000 initiated seven different demonstration projects in nine high-risk construction trades. The Ergonomics Rule was repealed in 2003, however valuable cooperative field research was conducted in construction prior to rule dissolution. This paper presents summaries and results of each project with the aim of providing the results to construction professionals and researchers seeking to identify and reduce injury risks and building costs. The projects were organized independently but each with the specific aims of conducting work in conjunction with industry, identifying “hazard zone” risk factors as defined by the rule, and identifying feasible solutions in agreement with company partners to mitigate these risk factors. Musculoskeletal injury risk factors were evaluated by ergonomist field observation and working group analysis. Solutions were developed through field work and consensus agreement with industry and labor representatives. Identified injury risk factors and technically feasible interventions are presented for the following trades: Roofing, residential framing, residential carpet and floor installation, commercial carpentry, commercial laborers, commercial concrete reinforcement, commercial concrete finishing, drywalling, and masonry.     

Work at Height Fatalities in the Repair, Maintenance, Alteration, and Addition Works

Hong Kong’s construction industry has shown significant improvement in safety performance since the turn of the century. The number of industrial accidents in the construction industry has decreased from 11,925 in 2000 to 3,833 in 2004, which is an encouraging drop of almost 68%. However, the category “fall of person from height” has always represented a large proportion of the industrial accidents, particularly fatal accidents. In 2004, fall of person from height represented just over 47% of the total number of fatal accidents in the construction industry. The statistics show that although the overall number of accidents has dropped immensely, the same does not apply for fall from height accidents. According to statistics provided by the Labor Dept. of the Hong Kong Special Administrative Region, there were a total of 22 fatal industrial accidents associated with fall of persons from height in repair, maintenance, alteration, and addition works during 2000–2004. When analyzing these case studies, 12 common factors were identified for analyzing these case studies and strategies were suggested to prevent recurrence of similar accidents in each case. The top five strategies were: (1) provide and maintain a safe system of work; (2) provide a suitable working platform; (3) (tier) provide safety information/training/instruction/supervision; (4) (tier) provide suitable fall arresting system/anchorage; and (5) maintain safe workplace.     

Evaluating Learning Approaches of Construction Students in Hong Kong through a Matrix Framework

Learning is a process of acquiring knowledge, and students may adopt different learning approaches to achieving their learning goals. While educationalists can draw up what they believe is a good construction curriculum for students, students’ learning would depend on their own learning approaches and attitudes. Acknowledging a lack of research on the learning attitudes of construction students, a matrix framework of learning approaches (MFLA) based on the relationships between three learning motives and three learning strategies is proposed in this paper. The MFLA enabled a major empirical survey to be carried out in Hong Kong to examine the learning characteristics of construction students. A questionnaire based on Biggs’s study process questionnaire was distributed to five groups of construction-related students in three universities in Hong Kong. The results of the survey indicate that seven of the nine hypothetical learning approaches exist in construction education in Hong Kong. The assortment of learning approaches used varied across the five student groups. As a result, different teaching and learning factors should be adopted by educators of construction students to meet the distinctive characteristics of students in various universities.     

Sleep Deprivation and Its Consequences in Construction Workers

Sleep deprivation contributes to fatigue, which can have a profound effect on an individual’s wellbeing, work performance, and safety. To investigate this phenomenon, a study was conducted on a sample of construction workers on a large construction project in Vancouver, Canada. This paper reports on the results from the workers wearing an actigraph 24 h/day for a full week to precisely measure their sleep and rest. The results enabled sleep efficiency and mental effectiveness levels to be determined by correlating them to blood alcohol concentration levels. This allowed determination of increased risk due to inadequate sleep. It was found that workers fell well under recommended sleep requirement guidelines of 8-h sleep per night, which resulted in an increase in risk of accident of 9%. Although further work is needed to better understand the coping mechanisms of fatigue and how the resulting fatigue factor could be measured and managed, this study indicates that workers in the construction industry suffer decrements in performance and are at higher risk of accident at home and work solely due to inadequate sleep.     

Construction Delays in Hong Kong Civil Engineering Projects

Construction delays are common in civil engineering projects in Hong Kong, inevitably resulting in contractual claims and increased project cost. This study was aimed, first, at gathering the perceptions of civil construction practitioners on how significant are the causes of delay; and, second, investigating whether the suggestions as stated in the report of the Construction Industry Review Committee (the Committee comprises members with good standing and knowledge in the construction and related fields as well as those from other professions who are responsible for examining the current state of the construction industry in terms of its output quantity, the quality of work, its environmental friendliness, site safety, its workforce and the system of supervision) are applicable to and effective at mitigating the corresponding delays with reference to a ranking order established using the mean score method. The extent of the differences in perception among the different respondent groups on these two issues was also examined using the rank agreement factor (RAF), percentage agreement (PA), and percentage disagreement (PD). The differences in the perceptions of the respondents on the significance of delays and the actual causes of delays for the six projects studied were also examined. The results of the study showed that the respondents tended to admit their own faults as shown in the top ten significant causes of delay. A strong consensus was found between the client and consultant groups on the significance of the various causes of delay (PA = 74%) and the effectiveness of mitigation measures (PA = 67%) compared with the other pairs of groups. The consultant and contractor groups held extremely different perceptions regarding the significance of various delay causes (RAF = 4.9 and PD = 32%) and the effectiveness of corresponding mitigation measures (RAF = 6.2 and PD = 47%). It is believed that the findings can provide much more insight for the construction practitioners as well as the researchers and thus help to improve the productivity and overall performance of civil construction projects in Hong Kong.     

Contributors to Construction Debris from Electrical and Mechanical Work in Hong Kong Infrastructure Projects

The crucial problem of construction debris is of increasing concern in Hong Kong. In the construction industry, the electrical and mechanical (E&M) installations in the infrastructure, for example, buildings, tunnels, or dams, are some of the major and usually complex components. Difficulty in coordinating the various trades affects productivity in general, and has a major impact on the quantity of construction debris. By identifying the sources of waste at each stage of E&M engineering work, some of the construction debris can be eliminated at the source during production. This paper investigates the critical production shortcomings in the E&M sector in Hong Kong. The study is based on a survey that includes a preliminary questionnaire survey, brainstorming exercises with a focus group, structured interviews with experienced frontline supervisors, and a second focus group exercise to test findings and proposed measures. The principal findings are that “poor coordination” and “design changes and/or errors” are major contributors to variations or change orders and rework, which in turn result in a high volume of construction debris. The results also indicate that construction debris can be minimized in the E&M sector of the construction industry, if the material wastes from incidental work are reduced and also controlled better in a new work process flow pattern through recommended construction project management improvements for reducing critical production shortcomings.     

Differences in Occupational Injuries, Illnesses, and Fatalities among Hispanic and Non-Hispanic Construction Workers

The U.S. Census Bureau estimates that one in four persons in the United States will be of Hispanic origin by 2050, up from one in eight in 2002. Driven by immigration, this dramatic growth in the Hispanic population will present unique challenges in the workplace. In construction, the increase in the Hispanic population has enabled the industry to meet its workforce demands. Unfortunately, this has occurred with costs in the health and safety of Hispanic construction workers. Using data from the U.S. Bureau of Labor Statistics’ current population survey, current employment survey, survey of occupational injuries and illnesses, and census of fatal occupational injuries, this study examines relative differences in injuries, illnesses, and fatalities between Hispanic and non-Hispanic construction workers by occupation. The findings show that differences in injuries, illnesses, and fatalities exist between Hispanic and non-Hispanic construction workers, although not always unfavorably toward Hispanics, and the difference does vary by occupation. The implication of the increasing size of the Hispanic construction workforce with respect to construction safety and health training needs is discussed.
