Academic literature on the topic 'Construction Hazard Prevention through Design (CHPtD)'

Fire hazard is a common threat in longhouses in Sarawak. Among things that are crucial in fire prevention is the evacuation route, in which highly dependent on house construction and layout. This study aims to observe the evolution of the Iban longhouse architectural design and materials used to build the longhouse. The qualitative analysis method was applied through 2D photo analysis as well as on-site visual observation and measurement. Construction materials used have been surveyed to determine its combustibility. It has been noted that longhouses have evolved over the years, from traditional to semi-traditional and modern longhouses design. The changes include the layout design and construction materials of the longhouses. Traditional and semi-traditional longhouses are often built using wooden materials that are highly flammable, while modern longhouses are made from concrete materials. The types of construction materials contribute to fire severity. It can be concluded that the longhouse architectural design, along with its construction materials, plays an essential role in the understanding of fire hazard, which will serve as fundamental on the longhouse fire reduction.

The “risk society” has become a key 21st century theme due to the economic expansion and population explosion spurred by science and technology development during the 20th century. We must create societies resilient against risk to preserve well-being and continue sustainable development. Although the ideal would be to create a society free from disaster and crisis, resources are limited. To achieve a more resilient society using these resources, we must become wise enough to identify the risks threatening society and clarify how we are to prepare against them. The traditional engineering approach is limited by its aim to reduce damage reduction as functional system of hazard, exposure, and vulnerability by focusing on mitigative action. We must instead add two factors – human activity and time dependency after a disaster – to make society more risk-resilient. The Research Institute of Science and Technology for Society (RISTEX) of the Japan Science and Technology Agency (JST) seeks to create new social, public, and economic value by solving obvious problems in society. In promoting science and technology R&D for society, RISTEX supports the building of networks enabling researchers and stakeholders to cooperate in solving societal problems. Our initiatives use R&D employing knowledge in the field of the humanities and social sciences, combined with natural sciences and technologies. Based on these existing accumulated knowledge and skills, scientifically verifying issues and lessons learned from these disasters, RISTEX launched a new R&D focus area, entitled “Creating a Community-Based Robust and Resilient Society,” in 2012. This R&D focus is to develop disaster risk reduction systems making society robust and resilient in the face of large-scale disasters. Two crucial key words in this focus area are “community” and “links.” Specifically, we must reexamine community frameworks to facilitate how diverse elements of society – industry, academia, government, and citizens – can be linked and activated in overcoming complex widespread disasters. Our R&D focus is grounded in the reality of urban and regional areas, and fosters mutual multilayered cooperation. In this issue, which mark the half-way point in the six-year RISTEX R&D focus program, we present 13 papers of reports on R&D studies selected by RISTEX in fiscal years 1 and 2, reviews appraising the academic significance of these reports, and studies that introduce new findings obtained through experimental studies. Seven papers resulted from four projects in the first year, three dealing with postdisaster reconstruction. The first, the Land Conservation and Resilience after Flooding Disaster project, deals with assisting in farmland restoration following heavy rainfall. Based on a detailed activity survey and geographical analysis, the report discusses significant roles played by community and incorporated non-profit organizations collaborating with groups outside affected areas. Of the two reports on the Redevelopment of Tsunami Impacted Coastal Regions, one analyzes the reconstruction planning process of a district completing its group relocation relatively early among communities in coastal regions devastated by the Great East Japan earthquake and tsunami. The other describes the computer reconstruction of village swept away by the tsunami, workshops conducted to improve reconstruction accuracy and the process by which community identity is strengthened by sharing common memories. Reports on the Disaster Mitigation Project of Traditional Buildings discuss current and future prospects for comprehensive disaster mitigation efforts in preservation districts based on a questionnaire focusing on the social capital in preservation districts for groups of traditional buildings. They also present results of action research aimed at community building based on connecting the historic townscape with people and organizations. The last first-year project deals with Computer-Assisted Structuring of Disaster Information. Related papers propose the design of a database schema for effectively processing disaster management information and use of natural-language processing to assist in this process. They also discuss issues related to the construction of an online information processing system for facilitating information coordination at disaster response headquarters that must process vast amounts of information in disaster response efforts. Six papers resulted from four projects among those selected in the second year. A paper on Resilient Metropolitan Areas Creation proposes multiscale community-based disaster mitigation planning preparing for a Nankai megathrust earthquake based on the need for a diverse region-wide discussion. They also report on workshops conducted based on this approach. One of two reports on Edutainment Disaster Relief Training proposes a sustainable training model based on scientific analysis of disaster medicine training – the first such attempt in medical relief. It describes implementation of an actual drill. The other report points out the need to classify disaster medicine learners into several hierarchical levels and discusses elements necessary for developing training programs as medutainment based on a comprehensive review of domestic sources on educational approaches and disaster medicine. The report on Structuring an Autonomous Regional Disaster Prevention Community describes how safety measures adopted since the 2011 Great East Japan earthquake by fire companies suffering many casualties from the disaster are effective in regions at risk of disasters other than tsunamis such as landslides. The report the Life Recovery of Public Rented Temporary Housing Dwellers presents ethnography and interview survey results with residents of public rented temporary housing regarding elements of life recovery such the housing situation, income and livelihood. Many field specialists agree it is essential to integrate science and technology in promoting R&D helping reduce disaster risks while achieving a resilient society. We must now put this concept into practice to ensure that research results are implemented. In effective risk and crisis communication, we focus on key prerequisites of people and society. We also address social issues using accumulated knowledge and technologies in individual fields as a starting point and linking these to the launch of new social implementations for achieving a resilient society. We express our sincere thanks and appreciation to all of the authors and reviewers involved in this special issue for their invaluable contributions and support.

Purpose The use of building information modelling (BIM) methodology has been increasing in the architecture, engineering, construction and operation sector, driven to a new paradigm of work with the use of three-dimensional (3D) parametric models. However, building information modelling (BIM) has been mostly used for as-built models of a building, not yet been widely used by designers during project and construction phases for occupational risks prevention and safety planning. This paper aims to show the capacity of developing tools that allow adding functionalities to Revit software to improve safety procedures and reduce the time spent on modelling them during the design phase. Design/methodology/approach To reach this objective, a structural 3D model of a building is used to validate the developed tools. A plugin prototype based on legal regulations was developed, allowing qualitative safety assessment through the application of job hazard analysis (JHA), SafeObject and checklists. These tools allow the automated detection of falls from height situations and the automated placement of the correspondent safety systems. Findings Revit application programming interface allowed the conception and addition of several functionalities that can be used in BIM methodology, and more specifically in the prevention of occupational risks in construction, contributing this paper to the application of a new approach to the prevention through design. Originality/value This paper is innovative and important because the developed plugins allowed: automated detection of potential falls from heights in the design stage; automated introduction of safety objects from a BIM Safety Objects Library; and the intercommunication between a BIM model and a safety database, bringing JHA integration directly on the project. The prototype of this work was validated for fall from height hazards but can be extended to other potentials hazards since the initial design stage.

Purpose With the rapid development of digital information and modelling software applications for construction, questions have arisen about their impact on construction safety. Meanwhile, recognition that designers can help reduce risks involved in construction, operation and maintenance via a prevention through design (PtD) approach (also known as design for safety) highlights the significance of digital technologies and tools to PtD. Thus, this paper aims to provide a systematic review of a wide range of digital technologies for enhancing PtD. Design/methodology/approach A five-stage systematic literature review with coding and synthesis of findings is presented. The review covers journal articles published between 2000 and 2020 related to the applications of various digital technologies, such as building information modelling (BIM), 4D, databases, ontologies, serious games, virtual reality and augmented reality, for addressing safety issues during the design phase in construction. Findings Analysis of the articles yielded a categorisation of the digital applications for PtD into four main areas: knowledge-based systems; automatic rule checking; hazard visualization; and safety training for designers. The review also highlighted designers’ limited knowledge towards construction safety and the possibility to address this by using gaming environments for educating designers on safety management and using artificial intelligence for predicting hazards and risks during design stage in a BIM environment. Additionally, the review proposes other directions for future research to enhance the use of digital technologies for PtD. Originality/value This paper contextualises current digital technology applications for construction health and safety and enables future directions of research in the field to be identified and mapped out.

Purpose: There are many tunnels under construction in Nepal as its mountainous country. Road, water supply, hydropower, and irrigation projects are under construction in Nepal through the tunnel. “Safety First” should be one of the main objectives of any construction projects mainly tunnel and shall be given high priority throughout the construction period. A single person alone cannot do it alone. A team including safety professionals to concentrate on health, safety, and environmental concerns shall be involved to ensure that safety environment will be maintained in the construction site. OSH is the relation between man and man, man and machine and man and environment. The paper aims to analyze the job safety of major selected construction activities during tunneling. Design/Methodology/Approach: Site Observation, Key Informant Interview (KII), and Study of Methods of Statement were done as main data collection tools. Job safety analysis and identification of activity with high risk level involved should be determined so that proper prevention and control mechanism could be determined and implemented. Drilling, excavation, blasting, mocking, scaling and shotcerting were major activities whose hazards, prevention mechanism and the responsible party were identified. Findings/Result: The study reveals that the main occupational hazards were mechanical and chemical hazards. Rockfall and landslide were noted as the major mechanical hazard whereas toxic gas and cement dust were the main chemical hazards. Similarly, noise and vibration were the main physical hazards and untimely payment of wages and leave were psychological hazards. It was reported that the major accident occurred at sites where the leg struck on steps of boomer while pulling a worker to save him from falling of boomer, penetration by fine grinding wheel material into the eye while carrying out grind cutting of drum and faint due to oxygen deficiency inside the tunnel. Some minor accidents were road traffic accidents, cut by sharp tools, fall/hit to/hit by objects, splashing of acids, burning caught by fire, etc. and the fatal accidents was one of the mechanics blown away by the erupted boomer tyres while filling up air into the same and one of the workers lost his life due to truck accident inside the work premise. The families of the demised had been compensated by the company. For safe construction requires the teamwork of sincere and coordinated effort of all stakeholders. Lack of regular inspection and monitoring at the site was the main cause of improper implementation of prevailing health and safety regulations. Originality/Value: The study is highly significant for working engineers to perform the task without any misfortune inside the tunnel. Paper Type: Project Management Action Research.

Health and safety during construction remains a worldwide challenge that the construction industry is facing. The German construction industry recorded an average of 110,000 accidents per year in the period of 2010 to 2019. A discernible trend toward a decrease in occupational accidents is not visible. In this context, traditional safety planning does not seem to be able to guarantee sufficient health and safety during construction. In line with the BIM Roadmap published by the German Ministry of Transport in 2015, it can be recognized that Building Information Modeling (BIM) is supposed to be increasingly used in upcoming years. This paper aims to identify how BIM could positively impact Occupational Health and Safety (OHS) during construction. Therefore, a thesis procedure, combining quantitative and qualitative research with an in depth literature review is introduced. This study reveals a high added value of using BIM for (1) safety rule checking and design validation and (2) safety education, training and communication. BIM as a decision supporting tool has the potential to reduce the underestimation of safety hazards and improve safety reporting, which have been identified as current vulnerabilities in the construction industry. Furthermore, an added benefit to sustainability following the concept of Construction Hazard Prevention through Design (CHPtD) is illustrated. In practice, however, BIM for OSH remains unused, while those working with BIM are not familiar with safety planning. This study indicates that in order to fully utilize the potential of BIM, intuitiveness and standardization is required, while those implementing BIM and those using BIM need to be aware of and willing to exploit the potential of new technologies. The challenge now is to recognize the potential of BIM in relation to OHS and to actively use BIM for health and safety purposes.
Att skapa en säker arbetsmiljö på byggarbetsplatsen är fortfarande en global utmaning för byggbranschen. I den tyska byggbranschen inträffade till exempel i genomsnitt 110 000 olyckor per år under perioden 2010-2019 och det syns ingen märkbar minskning. I detta sammanhang verkar traditionell säkerhetsplanering inte kunna garantera tillräcklig hälsa och säkerhet under byggandet. I samband med den strategiska BIM-implementeringsplanen som publicerades av det tyska transportministeriet 2015 ska Building Information Modeling (BIM) användas i allt större utsträckning under de kommande åren. Syftet med den här artikeln är att identifiera hur BIM skulle kunna ha en positiv inverkan på arbetsmiljö och säkerhet (OHS) på byggarbetsplatsen. Studien kombinerar kvantitativ och kvalitativ forskning med en djupgående litteraturgenomgång. Resultatet visar att det finns ett stort mervärde i att använda BIM för (1) kontroll av säkerhetsregler och validering av konstruktionen och (2) utbildning, träning och kommunikation om säkerhet. BIM som beslutsstöd kan möjliggöra en mer realistisk bedömning av säkerhetsrisker och förbättra säkerhetsrapporteringen, vilket har identifierats som aktuella sårbarheter i byggbranschen. Det finns också fördelar med att implementera konceptet Construction Hazard Prevention through Design (CHPtD). I praktiken är dock BIM för arbetsmiljöfrågor fortfarande oanvänd, samtidigt som de som arbetar med BIM inte är tillräckligt bekanta med säkerhetsaspekter. För att BIM:s potential ska kunna utnyttjas fullt ut krävs en ökad användarvänlighet och standardisering av verktygen. Samtidigt måste de som implementerar och använder BIM vara medvetna om och villiga att utnyttja den nya teknikens potential. Utmaningen är nu att förstå potentialen av BIM för arbetsmiljöaspekter och att proaktivt använda BIM för att öka säkerheten på byggarbetsplatser.

Construction Hazard Prevention through Design (CHPtD) is a process in which architects and engineers (A/Es) perform risk management (including identifying risks, evaluating risks and suggesting risk control measures) in the design stage to explicitly consider the safety and health of construction workers as they make design decisions on the permanent features of the design target. With early intervention, hazards can be effectively eliminated or controlled leading to safer sites during construction, use, and maintenance of the facility. However, the current structure and culture within the Taiwan construction industry inhibit the implementation of CHPtD. Consequently, the impacts of designs on construction worker safety are often left up to the constructor to address and mitigate after the design is complete which ignores the benefits CHPtD can provide to eliminate hazards from construction job-sites. Based on part of this current practice, the study was initiated to explore how to diffuse and implement CHPtD to the architecture industry in Taiwan. The research presented in this report looks outside of Taiwan to other countries like Australia, and the UK which have developed legislation for the implementing and diffusion of CHPtD in their construction industry since such legislation for CHPtD implementation doesn’t exist in the Taiwan architecture industry. The approach chosen for conducting the research study utilized a combination of targeted, expert interviews along with a structured on-line survey of design professionals within the Taiwan’s architecture industry. The research questions posed in this study explored respondents: knowledge, attitude and practices, and general application of the CHPtD concept. The responses provided by respondents were analyzed to further understand their perceptions of CHPtD and related issues. The majority of the respondents were supportive of the CHPtD concept, but their level of CHPtD knowledge, attitude and practices need to be improved. The recommendations made in this thesis were identified and fashioned based on the results obtained from the expert interview and the on-line survey conducted during the study. Diffusion and implementation of CHPtD into the Taiwan construction industry require attention to three (3) key points: knowledge, motivation, and aptitude. Each point addresses a fundamental need for affecting positive change and enabling anticipated outcomes of CHPtD implementation. The study findings reveal that each of the points needs to be fulfilled in some way to realize CHPtD success.

Addressing occupational safety and health needs in the design process to prevent or minimize the work-related hazards and risks associated with the construction, manufacture, use, maintenance, and disposal of facilities, materials, and equipment,” is how the National Institute for Occupational Safety and Health (NIOSH) defines Prevention Through Design (PtD) [1]. This concept is an idea whose time has come, including its extension to products, since product-related injuries also occur outside of the workplace. Using PtD techniques on consumer products will yield significant safety benefits. Besides the desire to provide well designed products, save lives, prevent injuries and avoid lawsuits, engineers have a professional responsibility to promote safety. The fundamental canon of the American Society of Mechanical Engineers (ASME) Code of Ethics states, “Engineers shall hold paramount the safety, health and welfare of the public in the performance of their professional duties.” [2] The first fundamental canon of the National Society of Professional Engineers (NSPE) Code of Ethics [3] is virtually identical. Codes and standards alone are usually not a guarantor of safety, as no document can foresee every application and situation. Codes and standards differ widely in their ability to produce a safe product or process simply from adherence to their requirements. Further, many codes and standards do not consider foreseeable or known misuse, which must be considered in PtD. PtD requires hazard evaluation followed by affirmative measures that address hazards and failure modes until an acceptable, likely nonzero, level of risk is reached. Such measures provide safety even when a momentary and foreseeable level of carelessness or inattention occurs.

During many years of working on oil and gas pipeline projects, the authors have experienced many occasions where safety and environmental professionals on the same project have conducted assessments without using an integrated approach, often to the detriment of the project. This ‘siloed’ behaviour is evident in the way that safety and environmental teams are often assembled at different times and have little to no interaction. An Environmental, Social and Health Impact Assessment (ESHIA) is used as a key mechanism to identify potential adverse consequences from a pipeline project in terms of unwanted impacts to fauna and flora and local communities. Simultaneously, major hazard studies are carried out for a pipeline project to identify major accident hazards risks to adjacent communities or at above ground installations (AGIs), usually from flammable events due to the transport of natural gas, crude oil or petroleum products. Both the ESHIA and the major accident hazards processes will identify appropriate prevention, control and mitigation measures to reduce the risk from the pipeline system and to manage the potential adverse consequences in the unlikely event of a major accident. Within the scope of many ESHIAs prepared now, there is an assessment of environmental and social impacts from ‘unplanned events’, which essentially are those major hazard events with the potential to cause multiple injuries or fatalities to people in the local community or at AGIs. As such events are likely to have a major consequence to the environment, particularly in the case of crude oil and petroleum products releases, it makes sense for such events to be studied by both safety and environmental professionals using an integrated approach. Such an integrated approach requires collaboration between various professionals from an early point within a project, as there are several different aspects with a pipeline project that will require the assessment of key personnel. For a pipeline project in the design stages, the main points for consideration are as follows: • Construction of the pipeline system, with major disruptions to the local environment from the construction itself (line pipe and AGIs) and due to the logistical requirements (traffic movements, movements of personnel and construction camps, moving major equipment across the world). • Operation of the pipeline system, with potential adverse impacts due to a loss of containment, as has been shown by many accidents in the past (e.g. Ref 1, 2). The key issue here is that the initiating events often remain the same, certainly with regard to operations where the initiating event will be a loss of containment. There may be adverse consequences to people, the biological environment and the physical environment, depending on the location and nature of the incident. For this reason joint participation in the hazard identification (HAZID) process by key safety, social and environmental professionals is considered beneficial to a pipeline project to ensure all potential initiators are included. In this case, the HAZID process would also include an environmental impact identification (ENVID), rather than conducting both processes separately. A major advantage of conducting an integrated approach is the potential cost-savings. By bringing together technical safety and environmental professionals at an early stage of pipeline project design, there is the potential to avoid ‘doubling-up’ on potential issues, as well as conducting two parallel processes that have many similarities. Perhaps more significantly, many potential adverse consequences (environmental, social and safety) can be prevented, controlled or mitigated through their early consideration during project design. Hence, by bringing together these different technical view-points at an early stage of pipeline system design, potential risk reduction options that would be beneficial to people and the environment may be identified. If ESHIA considerations and major accident hazard studies are evaluated in parallel during the early stages of a project (e.g. Appraise or Select), a pipeline project will have more available options to prevent potential impacts. As prevention of hazards is generally more cost-effective than designing in control and mitigation measures (for recovery of an incident), this will have a critical financial benefit. Furthermore, early changes to project design are generally far less costly than changes in the latter stages of a pipeline project; hence, early identification of prevention and risk reduction may be hugely beneficial.
