    Throughout the years, the construction industry has made an important contribution to the Malaysian economy. Moreover, the Ninth Malaysia Plan (2006–2010) has also played a significant role in the demands of executing major residential housing project developments where it has been observed that construction waste was one of the priority waste streams. Due to the increasing number in the population that is actively involved in economic activities, and the modernization of the country, the types of construction waste that are being produced, and identifying the source such as waste are becoming more complex. Therefore, appropriate actions and approaches are needed to be taken with respect to its effective management in handling the solid waste from construction sites. This paper is intended to review the issues and the challenges enclosed within the supply chain management mechanisms in order for improving construction waste management. Throughout this review, useful information and better understanding concerning the current issues, challenges and the supply chain management mechanisms would be made inclusive in the field to be explored. The findings would also assist in improving the quality and awareness on the construction waste management that is being practiced.

    Am. J. Ind. Med., 2013 Jan;56(1):65-76.
    PMID: 22544443 DOI: 10.1002/ajim.22056
    BACKGROUND: In Malaysia, surveillance of fatal occupational injuries is fragmented. We therefore analyzed an alternative data source from Malaysia's Social Security organization, the Pertubuhan Keselamatan Sosial (PERKESO).
    METHODS: We conducted a secondary data analysis of the PERKESO database comprised of 7 million employees from 2002 to 2006.
    RESULTS: Overall, the average annual incidence was 9.2 fatal occupational injuries per 100,000 workers. During the 5-year period, there was a decrease in the absolute number of fatal injuries by 16% and the incidence by 34%. The transportation sector reported the highest incidence of fatal injuries (35.1/100,000), followed by agriculture (30.5/100,000) and construction (19.3/100,000) sectors. Persons of Indian ethnicity were more likely to sustain fatal injuries compared to other ethnic groups.
    CONCLUSIONS: Government and industry should develop rigorous strategies to detect hazards in the workplace, especially in sectors that continuously record high injury rates. Targeted interventions emphasizing worker empowerment coupled with systematic monitoring and evaluation is critical to ensure success in prevention and control measures.

    PMID: 23186664 DOI: 10.1016/j.biortech.2012.10.023
    The current research investigates synthesis of methyl esters by transesterification of waste cooking oil in a heterogeneous system, using barium meliorated construction site waste marble as solid base catalyst. The pretreated catalyst was calcined at 830 °C for 4h prior to its activity test to obtained solid oxide characterized by scanning electron microscopy/energy dispersive spectroscopy, BET surface area and pore size measurement. It was found that the as prepared catalyst has large pores which contributed to its high activity in transesterification reaction. The methyl ester yield of 88% was obtained when the methanol/oil molar ratio was 9:1, reaction temperature at 65 °C, reaction time 3h and catalyst/oil mass ratio of 3.0 wt.%. The catalyst can be reused over three cycles, offer low operating conditions, reduce energy consumption and waste generation in the production of biodiesel.

    MyJurnal
    Ineffective construction waste management has become a serious problem that impacted significantly to environmental pollutions especially in a developing country like Malaysia. Despite the enactment of law by the government, Malaysia is still far behind as compared to other countries like Denmark and Hong Kong in terms of implementation of recycling and reuse of construction waste. Recycling and reuse of waste materials seems to be a profitable method that will boost the
    lifetime of landfills and cut down the usage of virgin natural resources. This paper discusses the practices of recycling and reuse of construction waste materials in the Klang Valley. A questionnaire survey was administered to 117 respondents from construction companies. The most common types of construction waste materials that can be recycled and reused are concrete, metal, asphalt, brick, plastic, cardboard, timber and glass. A descriptive analysis using Relative Important Index (RII) was used to rank the items asked in the survey. It was found that the most frequent types of recycling and reuse of construction waste materials based on ranking is timber,
    while the key benefit of recycle and reuse of construction waste is reduction of landfill space. On the other hand, the key challenge that affects recycling and reuse of construction waste is the risk of contamination. This study is beneficial for all parties involved in construction activities to achieve a more sustainable construction in Malaysia and throughout the world.

  8. A comparative life cycle assessment (LCA) of concrete and steel-prefabricated prefinished volumetric construction structures in Malaysia
    Balasbaneh AT, Ramli MZ
    Environ Sci Pollut Res Int, 2020 Dec;27(34):43186-43201.
    PMID: 32734541 DOI: 10.1007/s11356-020-10141-3
    In recent years, off-site volumetric construction has been promoted as a viable strategy for improving the sustainability of the construction industry. Most prefabricated prefinished volumetric construction (PPVC) structures are composed of either steel or concrete; thus, it is imperative to carry out life cycle assessments (LCAs) for both types of structures. PPVC is a method by which free-standing volumetric modules-complete with finishes for walls, floors, and ceilings-are prefabricated and then transferred and erected on-site. Although many studies have examined these structures, few have combined economic and environmental life cycle analyses, particularly for prefinished volumetric construction buildings. The purpose of this study is to utilize LCA and life cycle cost (LCC) methods to compare the environmental impacts and costs of steel and concrete PPVCs "from cradle to grave." The results show that steel necessitates higher electricity usage than concrete in all environmental categories, while concrete has a higher emission rate. Steel outperforms concrete by approximately 37% in non-renewable energy measures, 38% in respiratory inorganics, 43% in land occupation, and 40% in mineral extraction. Concrete, on the other hand, performs 54% better on average in terms of measures adopted for greenhouse gas (GHG) emissions. Steel incurs a higher cost in the construction stage but is ultimately the more economical choice, costing 4% less than concrete PPVC owing to the recovery, recycling, and reuse of materials. In general, steel PPVC exhibits better performance, both in terms of cost and environmental factors (excluding GHG emissions). This study endeavors to improve the implementation and general understanding of PPVC.

  9. Green construction practices: ensuring client satisfaction through health and safety performance
    Onubi HO, Yusof N, Hassan AS
    Environ Sci Pollut Res Int, 2022 Jan;29(4):5431-5444.
    PMID: 34420175 DOI: 10.1007/s11356-021-15705-5
    Studies have proven that client satisfaction (CS) is greatly affected by the nature of construction practices on site. However, not much attention has been given to CS in projects that adopt green construction practices (GCPs). This study examines the effect of GCPs on CS, and the means by which CS can be achieved through health and safety performance (HSP). This study also analyses how the relationship between HSP and CS could vary depending on the level of GCPs adopted. A questionnaire with 27 items drawn from literature was used in collecting data from class A contractors in Nigeria. The study's hypotheses were tested using the partial least squares structural equation modelling (PLS-SEM) technique. The findings of the study reveal that GCPs have a positive effect on CS. HSP proved to only partially mediate the relationship between GCPs and CS. The findings also show that the effect of HSP on CS is moderated by GCPs with the stronger effect from projects with low adoption of GCPs. The study's findings highlight the pivotal role of HSP in ensuring CS in construction projects that adopt GCPs. This study makes practical contributions to the body of existing knowledge by highlighting the need for concerted efforts by contractors such as investing in health and safety training and ensuring site workers wear personal protective equipment aimed at adhering to acceptable health and safety standards. This can be achieved through provision of funds for safety activities, monitoring, and supervision of workers to guarantee HSP which translates to CS while adopting GCPs. However, the obstacles to these are the lack of safety culture by construction organizations, lack of enlightenment on the part of construction site workers, and poor safety climate on the construction project site. Additionally, the study provides greater insight on the practice of green construction among contractors by showing that the effect of HSP on CS would differ considerably on account of the level of GCPs adopted.

  10. Developing a hierarchical framework for assessing the strategic effectiveness of sustainable waste management in the Somaliland construction industry
    Negash YT, Hassan AM, Tseng ML, Ali MH, Lim MK
    Environ Sci Pollut Res Int, 2023 May;30(25):67303-67325.
    PMID: 37103710 DOI: 10.1007/s11356-023-27060-8
    This study contributes to develop a hierarchical framework for assessing the strategic effectiveness of waste management in the construction industry. This study identifies a valid set of strategic effectiveness attributes of sustainable waste management (SWM) in construction. Prior studies have neglected to develop a strategic effectiveness assessment framework for SWM to identify reduce, reuse, and recycle policy initiatives that ensure waste minimization and resource recovery programs. This study utilizes the fuzzy Delphi method to screen out nonessential attributes in qualitative information. This study initially proposes a set of 75 criteria; after two rounds of assessment, consensus regarding 28 criteria is achieved among experts, and the 28 criteria are validated. Fuzzy interpretive structural modeling divides the attributes into various elements. The modeling constructs a six-level model that depicts the interrelationships among the 28 validated criteria as a hierarchical framework, and it finds and ranks the optimal drivers for practical improvement. This study integrates the best-worst method to measure the weights of different criteria in the hierarchical strategic effectiveness framework. The findings reveal that waste management operational strategy, construction site waste management performance, and the mutual coordination level are the top aspects for assessing strategic effectiveness in the hierarchical framework. In practice, the waste reduction rate, the recycling rate, water and land usage, the reuse rate, and noise and air pollution levels are identified to assist policymakers in evaluation. The theoretical and managerial implications are discussed.

  11. Analyzing the mediating effect of economic performance on the relationship between green construction practices and health and safety performance in Nigeria
    Onubi HO, Yusof N, Hassan AS, Bahdad AAS
    Environ Sci Pollut Res Int, 2021 Jul;28(27):36598-36610.
    PMID: 33709310 DOI: 10.1007/s11356-021-13334-6
    The adoption of green construction practices (GCP) has been on the increase in recent years as a means of reducing the negative effects of construction on the natural environment. However, GCP have been discovered to expose the construction workers to numerous health and safety (HS) risks, resulting from a decline in safety investment due to the economic burden associated with its adoption. This study explores the means through which GCP influence the HS performance of construction projects through economic performance. To obtain the views of contractors, a survey questionnaire was developed, and data was collected from project managers and site managers of "class A" contractors, with a response rate of 81.55%. The partial least squares structural equation modeling (PLS-SEM) technique was adopted to analyze the data. The results show that the effect of GCP on HS performance is fully mediated by economic performance. The study concludes that for projects that adopt GCP to have high levels of HS performance, they are required to have an optimal economic performance. Efforts should be intensified by the government in providing subsidies, tax waivers, and other incentives for adopters of GCP to ensure the economic performance of their projects since it guarantees high HS performance.

    PMID: 36620270 DOI: 10.3389/fpubh.2022.1086843
    INTRODUCTION: Buildings and infrastructure are the primary focus of the construction industry, which also includes related activities such as design, planning, demolition, renovation, maintenance, and repair. Safety performance is crucial to the industry's ability to work effectively in spite of hazardous conditions on the job site during any given project. Improving construction workers' safety performance in Malaysia requires an in-depth examination of the interplay between workers' psychological capital, work pressure, employee engagement, and safety participation.

    METHODS: Administrative and field workers from different divisions across Malaysia's six regions were randomly sampled to collect data for this study. The workers were given a total of 500 questionnaires, of which 345 were returned to the team of researchers. Based on the data analysis, there is an effective interaction between the factors tested toward safety performance.

    RESULTS: According to findings, psychological capital positively and significantly affected workers' work engagement. Also, work engagement greatly impacted both workers' safety performance outcomes. Also, as expected, worker pressure significantly and negatively affected workers' safety performance.

    DISCUSSION: Insights gained from this research have helped us better organize work and involve employees in safety activities/policies to boost workplace safety performance. The study also suggested that firms should reduce their employees' workloads because doing so would not lower their Psychological Capital but would instead fortify them to better carry out their duties in a risk-free manner.

    Ind Health, 2018 Nov 21;56(6):566-571.
    PMID: 29973468 DOI: 10.2486/indhealth.2018-0053
    In 2012, there were about 2.3 million deaths worldwide attributed to work. The highest workplace fatality rate (WFR) was reported on construction sites due to high risk activities. Globally, fall from height is the leading cause of fatal injuries for construction workers. The objectives are to determine Brunei Darussalam's demographic distribution of occupational fatality; identify causal agents and industry where occupational fatalities commonly occur; and determine WFR by year. This cross-sectional study retrospectively reviewed records of occupational fatality which were notified to the Occupational Health Division, Ministry of Health, from January 2012 until December 2016. Notified occupational fatalities in Brunei over a five-year period was 50. Most of the cases were in 31-40 age group. 38% of fatality cases occurred in Indonesian workers. 60% were from the Construction industry. 38% were due to fall from height. WFR averaged 5.28 and the highest industry-specific fatality rate was seen in the Construction industry, ranging from 27.94 to 56.45 per 100,000 workers. WFR for Brunei Darussalam from 2012 to 2016 was similar to that of Malaysia, but higher than Singapore and the UK. Industry-specific fatality rate for the Construction and Manufacturing industries were higher than those of Singapore and the UK.

    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.

    Int J Environ Res Public Health, 2021 03 29;18(7).
    PMID: 33805581 DOI: 10.3390/ijerph18073553
    Infrastructure projects are the foundation for essential public services and have an influential position in societal development. Although the role of infrastructure projects is substantial, they can involve complexities and safety issues that lead to an unsafe environment, and which impacts the project key stakeholders. Therefore, this study aimed to evaluate the barriers to implementing occupational safety in infrastructure projects in the Gaza Strip, which cause serious threats and reduce project performance. To evaluate the barriers, 39 items were highlighted and modified as per the construction context and environment, and which later were distributed in the form of a questionnaire, to get feedback from consultants and contractors. The analysis shows that in the safety policy barriers group, consultants and contractors both ranked the item "a contractor committed to an occupational safety program is not rewarded" first. In the management barriers group, consultants and contractors both ranked the item "safety engineer does not have significant powers, such as stopping work when needed" in the first place. In the behavior and culture barriers group, consultants and contractors both ranked the item "workers who are not committed to occupational safety are not excluded" in the first place. Overall, both consultants and contractors shared the same viewpoint in classifying the barriers in the working environment. The outcome of this study is beneficial for Palestinian construction industry policymakers, so they can monitor the highlighted barriers in on-going infrastructure projects and can modify the safety guidelines accordingly.

    Buniya MK, Othman I, Sunindijo RY, Kashwani G, Durdyev S, Ismail S, et al.
    Int J Environ Res Public Health, 2021 08 11;18(16).
    PMID: 34444218 DOI: 10.3390/ijerph18168469
    The construction sector is recognized as one of the most dangerous industries in the world. The situation is worsening in Iraq, as a result of a lack of attention to safety in the building industry and the poor implementation of safety programs. This research aims to identify the critical safety factors (CSFs) of safety program implementation in the Iraqi construction industry. The CSFs were first identified from a review of literature before being verified by construction practitioners, using semi-structured interviews. A questionnaire, based on the verified CSFs, was distributed to construction practitioners in Iraq. Exploratory factor analysis (EFA) was used to analyze the quantitative data, and the results show that the CSFs can be categorized into four constructs: worker involvement, safety prevention and control system, safety arrangement, and management commitment. Following that, partial least square structural equation modelling (PLS-SEM) was executed to establish the connection between safety program implementation and overall project success. The result confirms that safety program implementation has a significant, positive impact on project success. This article contributes to knowledge and practice by identifying the CSFs for implementing safety programs in the Iraqi construction industry. The successful implementation of a safety program not only improves safety performance, but also helps to meet other project goals.

  19. Fulltext Impact of 3D Printing on the Overall Project Success of Residential Construction Projects Using Structural Equation Modelling
    Waqar A, Othman I, Pomares JC
    Int J Environ Res Public Health, 2023 Feb 21;20(5).
    PMID: 36900821 DOI: 10.3390/ijerph20053800
    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.
