    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 utilization of waste materials from the palm oil industry provides immense benefit to various sectors of the construction industry. Palm oil clinker is a by-product from the processing stages of palm oil goods. Channelling this waste material into the building industry helps to promote sustainability besides overcoming waste disposal problems. Environmental pollution due to inappropriate waste management system can also be drastically reduced. In this study, cement was substituted with palm oil clinker powder as a binder material in self-compacting mortar. The fresh, hardened and microstructure properties were evaluated throughout this study. In addition, sustainability component analysis was also carried out to assess the environmental impact of introducing palm oil clinker powder as a replacement material for cement. It can be inferred that approximately 3.3% of cement production can be saved by substituting palm oil clinker powder with cement. Reducing the utilization of cement through a high substitution level of this waste material will also help to reduce carbon emissions by 52%. A cleaner environment free from pollutants can be created to ensure healthier living. Certain industries may benefit through the inclusion of this waste material as the cost and energy consumption of the product can be minimized.

    This study uncovered inhibiting factors to cost performance in large construction projects of Malaysia. Questionnaire survey was conducted among clients and consultants involved in large construction projects. In the questionnaire, a total of 35 inhibiting factors grouped in 7 categories were presented to the respondents for rating significant level of each factor. A total of 300 questionnaire forms were distributed. Only 144 completed sets were received and analysed using advanced multivariate statistical software of Structural Equation Modelling (SmartPLS v2). The analysis involved three iteration processes where several of the factors were deleted in order to make the model acceptable. The result of the analysis found that R(2) value of the model is 0.422 which indicates that the developed model has a substantial impact on cost performance. Based on the final form of the model, contractor's site management category is the most prominent in exhibiting effect on cost performance of large construction projects. This finding is validated using advanced techniques of power analysis. This vigorous multivariate analysis has explicitly found the significant category which consists of several causative factors to poor cost performance in large construction projects. This will benefit all parties involved in construction projects for controlling cost overrun.

    INTRODUCTION: The construction industry in Malaysia has been bedevilled by myriads of risk issues that have hampered its smooth operations in recent times. This paper is an empirical assessment that aims to examine the effect of coercive pressure on the relationship between organizational structure and construction risk management among construction industry in Malaysia.

    METHOD: Based on the proposed model, a quantitative method was employed to obtain data from G7 construction industry operating within the peninsular Malaysia. Out of the 180 copies of questionnaire, 165 copies were properly filled, returned, and used for the analysis. PLS-SEM was used to analyze the obtained data.

    RESULTS: The findings of the study affirmed that specialization, centralization, and management of risk by the construction industry had positive correlation.

    CONCLUSIONS: As anticipated, coercive pressure had positive moderating correlation with both formalization and the management of risk by the construction industry. Similarly, it was also found that in the course of carrying out construction activities, coercive pressure made significant interactive influence on formalization, specialization, and centralization. Practical Applications: Coercive pressure reduced the frequency of accidents among workers in the process of carrying out construction works.

    Construction and demolition waste continues to sharply increase in step with the economic growth of less developed countries. Though the construction industry is large, it is composed of small firms with individual waste management practices, often leading to the deleterious environmental outcomes. Quantifying construction and demolition waste generation allows policy makers and stakeholders to understand the true internal and external costs of construction, providing a necessary foundation for waste management planning that may overcome deleterious environmental outcomes and may be both economically and environmentally optimal. This study offers a theoretical method for estimating the construction and demolition project waste generation rate by utilising available data, including waste disposal truck size and number, and waste volume and composition. This method is proposed as a less burdensome and more broadly applicable alternative, in contrast to waste estimation by on-site hand sorting and weighing. The developed method is applied to 11 projects across Malaysia as the case study. This study quantifies waste generation rate and illustrates the construction method in influencing the waste generation rate, estimating that the conventional construction method has a waste generation rate of 9.88 t 100 m(-2), the mixed-construction method has a waste generation rate of 3.29 t 100 m(-2), and demolition projects have a waste generation rate of 104.28 t 100 m(-2).

    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.

    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.

    The massive growth of construction industry especially in the developing countries results in extensive quarrying activities which ultimately would lead to the depletion of natural resources. Apart from extensive extraction of the natural granite from the earth for concrete production, marble production industry is also majorly contributing to the quarrying activities. In addition, high volume of waste is generated by the marble production industry as 70% of marble is wasted during the production such as quarrying, cutting, processing and others which is environmental unfriendly. In a way to achieve sustainable construction, the present study is to utilise the waste marble in replacing the coarse aggregate in concrete production. The engineering performance including workability, compressive strength, ultrasonic pulse velocity (UPV) and chloride penetration were analysed. The raw waste marble obtained from the industry were crushed and sieved into maximum size 20 mm and used to replace the coarse aggregate at the level of 20%, 40%, 60%, 80% and 100% respectively. Results show that 60% of the replacement level has yield to optimum result by achieving the highest compressive strength and UPV at approximate 5% higher than the control. Meanwhile, the effect on chloride penetration resistance is more significant, i.e. approximate 19% better than the control. However, increasing the replacement level of waste marble has no significant effect on workability, although an increasing trend was observed.

    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.

    Malaysian construction firms have increasingly gained investment opportunities in foreign countries pushed by the competitive and saturated domestic market. However, the entry location decision involves complex factors to be considered by these firms prior to their international operations. Currently, based on a secondary data obtained from the Construction Industry Development Board (CIDB) Malaysia, there are twelve (12) firms that are actively operating in international markets. The main objective of this preliminary study is to develop an entry location assessment criteria (ELAC) model based on the performance of Malaysian construction firms in international markets. The ELAC formula was derived through a development of taxonomy criteria from previous studies. The construction firms’ performance was analyzed and ranked using a weightage score characterized under three (3) dimensions of country with the taxonomy criteria. First dimension involves entry location decision to countries in ASEAN, Non-ASEAN and both regions, while the second dimension involves entry location decision to ASEAN, Asia, Africa, United States of America and Europe while the third dimension involves entry location decision to countries categorized as Developing Countries (DLC); Least Developed Country (LDC); Newly Industrialized Countries (NIC); Developed Countries (DC); and Highly Developed Countries (HDC). The ELAC score shows that three (3) construction firms which are, Sapura Energy Berhad (66%), Gamuda Berhad (53%) and Sime Darby Berhad (50%) have sustained international operations in various locations by obtaining an ELAC score of more than 50% by venturing to ASEAN countries, developing countries and developed countries. Even though his study is limited to Malaysian construction firms, it provides significant information and contributes to the current knowledge in international market expansion. This ELAC model is useful especially for construction firms that are just beginning to explore foreign business opportunities or for the global players that are expanding geographically to new international markets.

    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.

    Value management explicitly targets to optimize value by providing necessary
    functions at the least cost without sacrificing quality and performance. However, the
    activities/methods of this technique in emerging economies are here and there
    related to informal methodology. Therefore, the occurrence of these activities in an
    evolving economy requires investigation. The exploration of the extent to which the
    measured variables influenced the latent factors informed the need for this study.
    Data was retrieved via self-administered questionnaire from 344 registered and
    practicing construction professionals in Nigeria. The data was analyzed using SPSS for
    descriptive analysis and Structural Equation Modelling (SEM). Kaiser-Meyer-Olkin
    measure of sampling adequacy revealed that the internal consistency of the
    developed research instrument was appropriate. Confirmatory factor analysis
    indicates satisfactory goodness of fit among acknowledged determinants of the
    model. Furthermore, the study revealed three (3) phases of the activities/methods of
    value management in the Nigerian construction industry which include: information,
    information/function analysis, and creativity/evaluation/development/presentation
    phases. This means that value management activities and methods are being
    practiced in Nigeria, however not as per the typical methodology or standard. The
    need to carry out the practice according to the formal value management
    methodology is therefore recommended.

    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.

    Construction industry is one of the major contributors towards Malaysian economy and socio-economy. It is an important
    industry gearing Malaysia towards developed nation status. However, fatalities in this industry are a crucial problem. Number of
    fatalities in this industry is the highest compare to other industries registered in Malaysia. The contributing factors can be separated
    into immediate (human and worksite elements) and underlying (management and external). Occupational safety and health (OSH)
    management is a challenge in the construction industry due to its hazardous nature. A framework of construction OSH management
    consisting of policy, process, personnel and incentive elements were tested. 13 respondents from 13 residential projects comprising of
    high-rise and low-rise in Pulau Pinang were interviewed. It was found that the immediate factors are being more recognized by the
    respondents compare to the underlying factors. Human element is perceived as the most significant contributor, while the external
    element is the least significant. In terms of construction OSH management, process and personnel elements are the most significant in
    developing an effective OSH management programme.

    Background: Substantial empirical research has shown conflicting results regarding the influence of organizational external factors on construction risk management, suggesting the necessity to introduce a moderator into the study. The present research confirmed whether rules and regulations matter on the relationships between organizational external factors and construction risk management.

    Methods: Based on discouragement and organizational control theory, this research examined the effects of organizational external factors and rules and regulations on construction risk management among 238 employees operating in construction companies in Abuja and Lagos, Nigeria. A personally administered questionnaire was used to acquire the data. The data were analyzed using partial least squares structural equation modeling.

    Results: A significant positive relationship between organizational external factors and construction risk management was asserted. This study also found a significant positive relationship between rules and regulations and construction risk management. As anticipated, rules and regulations were found to moderate the relationship between organizational external factors and construction risk management, with a significant positive result. Similarly, a significant interaction effect was also found between rules and regulations and organizational external factors. Implications of the research from a Nigerian point of view have also been discussed.

    Conclusion: Political, economy, and technology factors helped the construction companies to reduce the chance of risk occurrence during the construction activities. Rules and regulations also helped to lessen the rate of accidents involving construction workers as well as the duration of the projects. Similarly, the influence of the organizational external factors with rules and regulations on construction risk management has proven that most of the construction companies that implement the aforementioned factors have the chance to deliver their projects within the stipulated time, cost, and qualities, which can be used as a yardstick to measure a good project.

    Diverting waste material from landfill sites has a big implication for the creation of new markets and has environmental benefits through offsetting the need for the extraction of raw materials. Besides, the major attention especially in construction industry is the problem to make natural resources sustainable for three to four decades in future. However, in this study finely glass powder with pozzolanic properties is found to be a partial replacement for cement and can acts as filler in the microstructure of a mortar block. Thus, a study was conducted to see the effects of various proportions of windscreen glass waste powder (WGWP) in determining the degree of water absorption on mortar incorporated with WGWP and to determine the optimum replacement to the ordinary Portland cement (OPC) with WGWP. Several compositions of WGWP (0%, 5%, 10%, 15% and 20% by cement weight) of mortar cube sample were prepared and cured at 7, 28 and 60 days to undergo a water absorption test. From this research, it shows that the use of WGWP was found to be the best features pozzolanic enough to use as a partial replacement for cement and it can reduced the pores of mortar by blocking the large voids in the hydrated cement paste through pozzolanic reaction. In the term of water absorption, the lowest reading was achieved in 15% and it can be said that 15% replacement is the optimum replacement of OPC.

    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
