    The benefits of using structural lightweight concrete in construction industry, particularly in high rise buildings, over normal weight concrete are numerous. The main method of producing structural lightweight concrete is the use of lightweight aggregates instead of ordinary aggregates in concrete. Due to the limited resources for natural and artificial lightweight aggregates, the alternative sources for lightweight aggregates should be discovered from industrial wastes. Oil palm shell (OPS) and oil-palm-boiler clinker (OPBC) are two solid wastes from palm oil industry and are available in abundance in tropical regimes. The use of just OPS as coarse lightweight aggregate in concrete mixture has some drawbacks for concrete. The aim of this study was to investigate engineering properties of a lightweight concrete containing both of these aggregates. For this purpose, in this study, 50% (by volume) of OPS was replaced with OPBC in an OPS lightweight concrete. The test results showed that when OPS was substituted with OPBC, significant improvement was observed in the compressive, splitting tensile and flexural strengths. In addition, initial and final water absorption as well as drying shrinkage strain of blended coarse lightweight aggregate concrete were significantly less than OPS concrete.

    After a decade of research and development, 3D printing is now an established technique in the construction sector, complete with its own set of accepted standards. The use of 3D printing in construction might potentially improve the outcome of the project as a whole. However, traditional strategies are often used in the residential construction industry in Malaysia, which causes serious public safety and health issues along with a negative impact on the environment. In the context of project management, overall project success (OPS) has five dimensions, such as cost, time, quality, safety, and environment. Understanding the role of 3D printing in relation to OPS dimensions in Malaysian residential construction projects would allow construction professionals to adopt 3D printing more easily. The aim of the study was to find the impact of 3D construction printing on OPS while considering the implications for all five dimensions. Fifteen professionals were interviewed to first evaluate and summarise the impact factors of 3D printing using the current literature. Then, a pilot survey was conducted, and the results were checked using exploratory factor analysis (EFA). The feasibility of 3D printing in the building sector was investigated by surveying industry experts. Partial least squares structural equation modelling was used to investigate and validate the fundamental structure and linkages between 3D printing and OPS (PLS-SEM). A strong correlation was found between 3D printing in residential projects and OPS. Highly positive implications are indicated by the environmental and safety dimensions of OPS. Malaysian decision-makers may look to the outcomes of introducing 3D printing into the residential construction industry as a modern method for increasing environmental sustainability, public health and safety, reducing cost and time, and increasing the quality of construction work. With this study's findings in hand, construction engineering management in Malaysia's residential building sector might benefit from a deeper understanding of how 3D printing is used for improving environmental compliance, public health and safety, and project scope.

    This paper seeks to clarify Building Information Modelling (BIM) and its implementation in Malaysia.
    Most developed countries that have implemented BIM in the construction industry have found it effective. This paper reviews existing literature on the implementation of BIM and examines the implementation strategies that have been developed. The review highlights numerous advantages of BIM in construction, which include, among others, reducing cost, time, carbon burden and capital cost. BIM can also help increase broader efficiencies and improve coordination and communication between each party. However, implementing BIM is complicated and requires efforts from both the government and the private sector. While the implementation of BIM may reduce costs in developed countries, it may not do so in developing countries; in Malaysia, for instance, costs act as an initial barrier. Other obstacles to implementing BIM in Malaysia include application system requirements and lack of knowledge and readiness to change. To facilitate its implementation in the construction industry, the Malaysian government needs to hold seminars to promote a better understanding of BIM. They may also introduce a properly structured BIM course by preparing a standard code of practices and guidelines for BIM in the education sector.

    The probability of the construction accident to happen is high due the nature of
    Construction work that involves complex activities, methods, machineries, materials
    and hazards. The occupational safety and health (OSH) law and regulations are
    mandatory for every construction project to uphold. Responsibilities to ensure the
    safety and health at the workplace lies with those who create the risk and with those
    who work with the risk. The owner or client of the construction project has the upper
    hand in determining the standard of OSH implementation in their project through
    contract documents. If the contract documents comprehensively spell out OSH
    requirements and cover all OSH cost, then the issues of contractor not implementing
    OSH measures could be minimized. The objective of this study is to identify
    Occupational Safety and Health requirements (OSH) in the contract document of
    selected construction projects. To achieve this objective, a total of seven contract
    document was collected from several construction companies. The qualitative analysis
    was performed to identify the extent of OSH requirements and costs are being
    mentioned in the contract documents. The finding shows that most of the contract
    document contains very little emphasis on OSH requirements and budgeting. Only one
    contract contains, an appendix that spell out about the safe work practices for
    construction works. The visible allocated budget for OSH requirements for all seven
    contracts is very minute range from 0.21% to 1.99% of contract value. In order to
    ensure that occupational safety and health is properly implemented, safety needs must
    be included in the budget because implementation it is not free, this can be achieved
    by making it a permanent feature in all bills of quantity of the project.

    The control of cost and time in construction projects is one of the most important issues in construction since the emergence of the construction industry. A successful project should meet not only quality output standards, but also time and budget objectives. The management and control of cost and time in construction is fundamental in every project. An effective cost and time management and control technique for construction projects is important in managing risk of cost overrun and delay in completion of projects. Construction projects are becoming more complex as they now involve many stakeholders from different disciplines. The emergence of Building Information Model (BIM), an alternative technology is believed to solve issues related to project cost and time control as it efficiently increases collaboration between stakeholders. The aim of this paper is to review and summarise the causes of delay and cost overrun in construction industries, which are the main causes of disputes and abandonment of projects in the industry. It was found that delays and cost overrun eat deep into the industry and leave the construction industry with a bad image for decades even with rapid advancement in technology. The review of the applications of BIM showed that most of the applications are geared towards minimising construction cost and time spent on projects. This means that the use of BIM in the management of construction projects has great impact on project cost and time.

    The construction industry is recognized as one of the most hazardous industries globally due to the dynamic on site activities and labour-intensive characteristics. The construction tasks are physically and cognitively demanding therefore the construction workers are prone to work fatigue which compromises safety performance. The evaluation of fit for duty, or fitness for work (FFW) aims to determine if workers are at risk of adverse impacts of ill-health, injury or accidents. This systematic review aimed to critically summarize up-to-date measures and evaluation tools that were employed to monitor work fitness or fatigue specifically among construction workers. Adhering with the PRISMA protocol, three databases were searched from the inception to 2022, with a total combination of 37 keywords, concluding to the selection of 20 relevant articles. The Mixed Method Appraisal Tool (MMAT) was used as the guide for the study appraisal. A total of 20 articles were reviewed, published from 2008-2022. Majority of the studies employed experimental design. The review identified the subjective evaluation scales and objective measurement tool. The subjective self-response questionnaires can be categorized into single dimension or multidimension covering both physical and mental fitness; whereas the objective measurement tool can be categorized into physiological metrics, physical and cognitive performance measure. The available scientific evidence has raised the relevant issues for on-site practicality and potentially guide the formulation of evidence-based guidelines for the FFW assessment in the construction industry.

    INTRODUCTION: Falling from heights can be a serious and potentially life-threatening hazard. In Malaysia, falls from heights are one of the leading causes of workplace accidents and fatalities. The Malaysian Department of Occupational Safety and Health (DOSH) reported that the year 2021 recorded an alarmingly high number of fatalities, of which the majority of the injuries were due to falls from heights.

    OBJECTIVE: The purpose of this study is to understand the relationship between the different variables associated with fatal falls from heights, which will help identify potential areas to work on to prevent these types of injuries.

    METHODS: The study analyzed 3,321 fatal falls from height accidents from 2010 to 2020 DOSH data. Data were cleaned and normalized to extract relevant information for analysis, with agreement on variables and reliability achieved through independent sampling.

    RESULTS: This study found that general workers were the most vulnerable category to fatal falls, with a 32% yearly average, whereas supervisors were the least vulnerable, with 4%. Roofers recorded a yearly fatal falls average of 15.5%, followed by electricians with 12%. Cramer's V results ranged from negligible, weak, and strong correlations; strong to moderate correlation between the dates of injuries and the factors used in this study, whereas the direct and root causes recorded a weak to negligible correlation with the rest of the variables.

    CONCLUSIONS: This study provided a better understanding of the working conditions of the Malaysian construction industry. By analyzing fall injury patterns and uncovering the factors, direct and root causes relationship with other variables, it was clear how severe the Malaysian workplace conditions were.

    PRACTICAL APPLICATIONS: This study will help better understand fatal fall injuries in the Malaysian construction industry and help develop prevention measures based on the uncovered patterns and associations.

    The construction sector is among the fastest growing sectors in Malaysia; it consumes a vast amount of natural resources and produces a massive volume of construction and demolition waste. The waste is collected in a decentralised manner by sub-contracted companies. It is challenging to obtain reliable information on the amount of construction waste generated, because it is hard to determine its exact quantity and composition. Therefore, this study proposes a quantitative construction waste estimation model for residential buildings according to available data collected from the Construction Industry Development Board, Malaysia. In the development of this model, a theoretical investigation of the construction procedure and the construction waste generation process was conducted. The waste generated rate was determined as 25.79 kg m-2 for new residential constructions, which translates into about 553,406 t of anticipated waste annually.

    The construction industry is one of the largest sectors in Malaysia. This industry has become one of the main contributors
    for national economic development and consistently contributes 3% to 5% to the national Gross Domestic Product (GDP). This
    sector has also opened up job opportunities for various levels of employment. High demands and rapid urbanization offer huge
    opportunities for registered contractors. Despite contributing in enhancing national economics, this sector has been regarded as one
    of the most dangerous and hazardous workplaces due to the type of nature and the job activities at construction sites. According to
    the International Labour Organization (ILO), 2.3 million fatalities related to occupational accidents and illnesses are estimated to
    occur each year. Furthermore, 4 percent of world GDP is estimated to be lost due to occupational accidents and illnesses. The number
    of fatality accidents in the construction industry was the highest with 652 cases of non-permanent disability (NPD) and permanent
    disability (PD) accidents in the period 2007 to 2015, equivalent to 72.44 cases per year and representing 48.77% of the construction
    industry. The huge gap between the number of accidents reported to SOCSO and DOSH becomes a major concern due to a rising
    number of underreported cases of fatalities and injury in the construction sector, especially those involving foreign labour. The margin
    between accidents reported to SOCSO and DOSH is 97.49%. Regards to rapid developments, safety measures to improve performance
    management of OSH should be emphasized to reduce losses of life, property and productivity.

    Precast concrete panel is one of the Industrial Building System (IBS) components currently used in modern construction industry, especially, in a highly populated urban area in Malaysia, owing to its cost and time efficiency in a project completion. However, the constraints lie in Musculoskeletal Disorders (MSDs) when IBS workers manually lift the concrete panel repeatedly. The aim of this study is to analyze the recommended weight limit (RWL), lifting index (LI) and physiological experience among workers while lifting precast concrete panel with 3300mm x 600mm size and compressive strength of 40MPa. The methods involved include a survey through the Nordic questionnaires, interview sessions, NIOSH lifting index calculation, recommended work limit calculation, Rapid Upper Limb Assessment (RULA) and video recording. The results yielded the MSDs problem. The guidelines of recommended weight limit and lifting index are produced. They benefit workers and increase their awareness on the MSDs issues.

    Nanoparticles are defined as ultrafine particles sized between 1 and 100 nanometres in diameter. In recent decades, there has been wide scientific research on the various uses of nanoparticles in construction, electronics, manufacturing, cosmetics, and medicine. The advantages of using nanoparticles in construction are immense, promising extraordinary physical and chemical properties for modified construction materials. Among the many different types of nanoparticles, titanium dioxide, carbon nanotubes, silica, copper, clay, and aluminium oxide are the most widely used nanoparticles in the construction sector. The promise of nanoparticles as observed in construction is reflected in other adoptive industries, driving the growth in demand and production quantity at an exorbitant rate. The objective of this study was to analyse the use of nanoparticles within the construction industry to exemplify the benefits of nanoparticle applications and to address the short-term and long-term effects of nanoparticles on the environment and human health within the microcosm of industry so that the findings may be generalised. The benefits of nanoparticle utilisation are demonstrated through specific applications in common materials, particularly in normal concrete, asphalt concrete, bricks, timber, and steel. In addition, the paper addresses the potential benefits and safety barriers for using nanomaterials, with consideration given to key areas of knowledge associated with exposure to nanoparticles that may have implications for health and environmental safety. The field of nanotechnology is considered rather young compared to established industries, thus limiting the time for research and risk analysis. Nevertheless, it is pertinent that research and regulation precede the widespread adoption of potentially harmful particles to mitigate undue risk.

    The construction industry is one of the major sectors in Malaysia. Apart from providing
    facilities, services and goods it also offers employment opportunities to local and
    foreign workers. In fact, the construction workers are exposed to high risk of noises
    being generated from various sources including excavators, bulldozers, concrete mixer
    and piling machines. Previous studies indicated that the piling and concrete work were
    recorded as the main source that contributed to the highest level of noise among
    others. Therefore, the aim of this study is to obtain the level of noise exposure during
    piling process and to determine the awareness of workers against noise pollution at
    the construction site. Initially, the reading of noise level was obtained at construction
    site by using a digital sound level meter (SLM) and noise exposure to the workers was
    mapped. Readings were taken from four different distances; 5, 10, 15 and 20 meters
    from the piling machine. Furthermore, a set of questionnaire was also distributed to
    assess the knowledge of regarding noise pollution at the construction site. The result
    showed that the mean noise level at 5 meters distance was more than 90 dB, which
    exceeded the recommended level. Although the level of awareness of regarding the
    effect of noise pollution is satisfactory but majority of workers (90%) still did not wear
    ear muffs during working periods. Therefore, the safety module guidelines related to
    noise pollution controls should be implemented to provide a safe working environment
    and prevent initial occupational hearing loss.

    This research covers the current status of occupational health and safety (OHS)-related practices in the informal construction segment of Pakistan. Data were collected, through interviews, from 316 construction sites employing 3577 workers. The results of the study reveal that both employers and workers lack knowledge of OHS laws/standards and no practices of this nature are enacted at these construction sites. Alarmingly, work-related accidents, whenever they happen, are not given due attention and there is no formal injury-report system. The informal construction industry employs a huge portion of the informal workforce, and lack of OHS happens at tremendous human cost. These research findings may thus play their role in strengthening the case for reforms in the sector. This study, if properly utilized, may also enable employers of the sector by increasing their knowledge about OHS practices and, as a result, trying to offer safer environments for their workers.

    Timber scaffold boards have been widely utilised in the offshore construction industry. However, technical specifications
    and inspection procedure for the application of scaffold boards from a wood material were inadequate. In the development
    of the standard requirements, evaluation of actual engineering practices could indicate the level of workplace safety. A
    study was conducted to identify risk and safety measures concerning the use of timber scaffold boards in construction.
    This article discusses on the occupational risks and ergonomics issues of the scaffolding application based on the physical
    and mechanical conditions of tropical timber scaffold boards extracted from offshore oil and gas rigs. The boards were
    exposed to a seasonal climate of East Coast monsoon of South China Sea between November and February. The scaffolding
    application extended up to 20 m directly above the ocean surface and some boards were completely immersed below
    the ocean surface particularly during elevated tidal waves. Some of the boards were installed as the on-deck platforms.
    Forty scaffold boards fabricated from tropical timber species were evaluated. Physical characteristics of the boards
    were described by natural and man-made factors. A three-point bending test was conducted to determine the maximum
    load capacity of each board and the mode of fracture was evaluated. Timber identification test was conducted to identify
    the groups of the timber being used. The microscopic observation confirmed the presence of hyphae which indicated the
    biological deterioration has happened in some of the boards. Occupational risks were summarised based on the results
    of the physical and mechanical assessments

    The construction industry plays a significant role in contributing to the economy and development globally. During the process of construction, various hazards coupled with the unique nature of the industry contribute to high fatality rates. This review refers to previous published studies and related Malaysian legislation documents. Four main elements consisting of human, worksite, management and external elements which cause occupational accidents and illnesses were identified. External and management elements are the underlying causes contributing to occupational safety and health (OSH), while human and worksite elements are more apparent causes of occupational accidents and illnesses. An effective OSH management approach is required to contain all hazards at construction sites. An approach to OSH management constructed by elements of policy, process, personnel and incentive developed in previous work is explored. Changes to the sub-elements according to previous studies and the related Malaysian legislation are also covered in this review.

    Malaysian construction sector is regarded as critical in the field of health because of the high rates of accidents and fatalities. This research aimed to determine the prevalence, sources and severity of injuries and its association with commitment to safety among foreign construction workers. A cross-sectional study was conducted among 323 foreign construction workers from six construction projects of a large organization in Malaysia, using a simple random sampling method. Data was collected using a structured questionnaire to assess work-related injuries and safety commitment. The collected data was analysed by SPSS 22.0 using descriptive statistics and χ2 test. The prevalence of work-related injuries in a one year period was 22.6%, where most of the injuries were of moderate severity (39.7%) and falls from heights represented the main source (31.5%). The majority of the foreign construction workers had perceived between moderate and high safety commitment, which was significantly associated with work-related injuries. The results also showed a significant association of work-related injuries with the company's interest in Safety and Health, Safety and Health training, and safety equipment. Thus, the implementation of new procedures and providing relevant trainings and safety equipment; will lead to a decrease in injury rates in construction sites.
