Authors:Taki Eddine Seghier; Mohd Hamdan Ahmad, Yaik-Wah Lim Abstract: Concrete Usage Index (CUI) is one of the very used sustainability criteria related to building materials available in the Malaysian and Singaporean building standards. Often, CUI assessment is achieved either by manual calculation or semi-automated methods based on Material Take-off functionalities provided by the BIM tools. Both of these methods are relatively time-consuming, error-prone, and require much human intervention. The purpose of this paper is to develop a computational BIM-based tool for the automation of Concrete Usage Index (CUI) assessment and rating. This developed tool takes advantage of the data embedded in the BIM model and the automated CUI compliance-checking which is developed using a Visual Programing Language (Dynamo for Revit). For validation purpose, this tool has been tested on a BIM model of an existing building and the results were compared with Revit Material Take-off method. Thus, Auto-CUI tool automates the process of data collection, calculation and the generation of the CUI report. In addition to that, the generated results are as accurate as the material take-off method. Auto-CUI will support design decision-making during the design stage by providing an interactive feedback of CUI actual score and rating. Thus, the project team will be able to compare different design options according to concrete usage. Furthermore, it will allow designers to avoid CUI’s cumbersome calculations and inaccurate outputs. Even though, the usage of this tool does not require programming skills, developing this tool further as a plug-in for Revit would be helpful in reducing computation time as well as enhancing the generation of CUI report.

Authors:Gabriel Hoh Teck Ling; Jia Chyi Pung Abstract: Brownfield development has become one of the sectors to be emphasised imperatively due to emerging greenfield scarcity throughout Malaysia. A brownfield site may have real or perceived contamination issues that require intervention to revive for beneficial use. As of to-date, there is still a number of brownfield sites in Iskandar Malaysia, albeit brownfield revival projects, via planning and policy measures, have been carried out over the years. In this light, a mode of governance is suggested to be a significant factor in the stagnation and success of brownfield development. Therefore, this paper aims to revisit the urban governance modes of brownfield development in Iskandar Malaysia, with a focus on commercial brownfield development. Specifically, two objectives are highlighted in this paper: (i) to assess the site-level success of completed brownfield developments, namely the Paradigm Mall, Skudai and the Danga City Mall, Johor Bahru; and based on the assessment outcomes, it is then (ii) to identify an efficient and suitable mode of governance for commercial use brownfield development. A measuring tool and an indexing scheme to screen brownfield sites were employed alternately. Results show that the Paradigm Mall achieved a higher site-level success compared to the Danga City Mall. Under this light, compared to the corporatist mode of governance, the clientelistic mode of governance with a material objective is highly in relation to a better success of commercial use brownfield development in the background of Iskandar Malaysia. These findings offer valuable messages and insights to practitioners, particularly local policy-makers, that an often-neglected governance mode approach is essential in determining the brownfield development outcome.

Authors:Hamizah Liyana Tajul Ariffin; Norhazren Izatie Mohd, Nur Emma Mustaffa, Shamsulhadi Bandi, Cecelia Ho Mei Chee Abstract: Malaysia is making an aggressive effort of transformation to become a fully developed country. As one of the pillars for transformation, the construction industry has been undergoing a major reform with regard to the traditional method of construction. In recent years, the Industrialised Building System (IBS) has been promoted extensively with the government taking a lead with the practice. Studies showed that IBS has been able to expedite construction process, improve the time taken to accomplish a project, improve building quality, able to control cost and human resources, which in overall, raise occupational health and safety standard of construction. Despite, as most IBS projects were carried out under the traditional procurement method, the full benefits of IBS are somehow obscured. Several issues such as work delay, lack of communication and integration, lack of knowledge and an increase in cost, which are synonymous to the traditional procurement method appear to outweigh the benefit of IBS. Hence, this research aims to suggest an alternative to the traditional procurement method with regard to IBS project implementation. The focus of this research has been on the challenges and innovative procurement methods most suited for IBS project. Two objectives were outlined: (1) to identify issues faced by the client on current procurement method in IBS project; and (2) to identify the client’s perspective on innovative procurement method most suited for IBS project. Data for this research was collected through semi-structured interviews with five respondents from five major developers having experience in IBS project implementation. The results from the thematic analysis revealed that apart from the common issues which ascend from the sequential nature of the traditional procurement method, design integration issue was opined to aggravate the situation. Unanimously, respondents agreed that partnering is the way forward for IBS project implementation in the Malaysian construction industry. This research contributes by providing important pointers for the local construction industry to move forward with IBS project implementation. PubDate: Sun, 06 Jan 2019 08:35:55 +080
Authors:Nur Emma Mustaffa; Hamizah Liyana Tajul Ariffin, Norazam Othman, Shahida Shaima Shamsudin Abstract: Conditional payment such as “pay when paid” or “pay if paid” can create negative chain effect on the parties in construction projects, resulting in delay on the completion of a project, adversarialism and may affect a contractor’s reputation. Asian International Arbitration Centre (AIAC) has launched a standard form of contract which is Construction Industry Payment Adjudication Act (CIPAA) compliance with the aim to reduce payment issues. The aim of the research is to identify whether the clause for “direct payment under CIPAA 2012” of the new AIAC standard form of contract can facilitate problems in direct payment. In achieving the aim of the research, five legal cases were analysed and thirty questionnaires forms were distributed. Legal cases analysis findings highlighted that the major reasons of the direct payment issue being referred to court is due to the validity of the direct payment agreement between the disputant’s parties. Based on the cases heard before CIPAA enactment, the findings show that out of the three cases, the disputants went to litigation because of the legality of direct payment agreements. Most of the agreements were made orally. For cases analysed after CIPAA was enacted, the findings show that the disputant parties do not opt for adjudication and that the main contractors try to mitigate their responsibilities to the employer. The results from the questionnaires distributed established that, the direct payment clause could be successfully adopted for future use of the industry. Eventhough the AIAC standard form of contract has been formally introduced to the industry, but it is not widely used. From the findings of the questionnaire, it shows that with encouragement and support from the industry, direct payment clause of AIAC standard form of contract have the potential in reducing payment issues in the future. With the remodeling of standard form of contracts that are available in construction industry to be CIPAA compliance , it is hoped that this move may scale down the prevalent payment issues in Malaysian construction industry.

Authors:Norhazren Izatie Mohd; Kherun Nita Ali, Shamsulhadi Bandi, Fuziah Ismail Abstract: In recent years gaming products have increasingly been used to enhance learning and training development in academic and commercial sectors. Games have become more pervasive; they have been adopted for use in many industries and sectors such as defence, medicine, architecture, education, and city planning and government as tools for workers development. In Malaysia, it has been reported that the construction industry holds the third highest record of occurrences of accidents at work. Therefore, safety training is inevitable to reduce the alarming rate of accidents on construction sites. However, currently, available safety training approaches are still lacking in terms of delivering hands-on training and are more theoretical- instead of being more practical-based. This is due to the nature of the construction environment itself in which safety training involving certain hazards that cannot be implemented hands-on as it may bring harm to trainers, trainees and the environment. Gaming is an approach that applies technology to provide an almost real experience with interactive field training, and also supporting the theory of learning by doing with real case scenario. The purpose of this paper is to seek and explore the differences in existing gamification genres such as simulation game, role-playing, action game, strategy game and etc. Data were collected through available literature. The findings of the study show that serious game is a suitable genre to be adopted as an approach in hazard identification training for the construction industry in Malaysia.

Authors:Ezekiel Babatunde Ogunbode; Mohamad Yatim Jamaludin, Hazim Bin Affendi, Azmahani Abdul Aziz, Yunus Mohd Ishak, Hazlan Abdul Hamid Abstract: The deterioration of concrete structures is a matter of critical concern as it threatens the durability and strength of concrete structures. Kenaf fibrous concrete composite (KFCC) can be used with advantage in new structures such as precast elements, as well as the strengthening, repair and rehabilitation of old structures to improve their durability properties. These structures are composite components, with parts as Plain concrete (PC) and others as KFCC. This study, therefore, investigated the interfacial bonding behaviour between KFCC and PC. Shear, tensile and compressive tests were carried out to measure the bond strength in shear, direct tension and compression respectively for PC to PC, PC to KFCC and KFCC to KFCC interface. Three different types of concrete grade (25, 35, and 45 MPa) were produced for the KFCC and one type of concrete grade (35 MPa) for the substrate PC. The outcome of the test showed that KFCC had an excellent interlock with the surface of the PC substrate, and thus, gives bond strength greater than the strength of PC. New concrete with the highest concrete grade of 45 MPa ensued in high compressive, tensile and shear bond strength. PubDate: Sun, 06 Jan 2019 08:35:54 +080
Authors:Ahmad Faiz Azizi Ahmad Fauzi; Kherun Nita Ali, Roslan Amirudin Abstract: Augmented reality (AR) has the potential to enhance the teaching and learning experience in construction technology which involves the learning of construction processes and understanding the construction elements. Augmented reality also provides the ability to change and improve the nature of education. This is due to the possibility of overlaying media onto the real world for content consumption using smartphones and tablets devices, which enables students to access information at anywhere and anytime. However, before implementing a new approach to teaching, the state of whether the students are ready to use AR have to be identified. This also goes toward what the students expect when using AR in learning, how do they accept using AR and effectiveness of using AR in learning. Therefore the purpose of this study is to (1) Identify the readiness of students on using AR in teaching; (2) Identifying what do the students expect when using AR in learning construction technology; (3) Identifying the student’s acceptance of AR in learning; (4) The effectiveness of AR in construction technology learning. A quantitative method of analysis has been implemented measuring the mean score of objective 1-3 based on the student’s responses to the questionnaire. On the other hand, the second phase of the study which is to determine whether using AR is effective in learning was done by comparing pre-test and post-test results. Results from the study shows assuring indicators that students accept the usage of AR in construction technology education, the application also fulfils their expectations on what AR could aid in the learning process and for student’s acceptance, the result shows that students accepted the usage of AR as a learning tool. Meanwhile, the results regarding AR effectiveness on construction technology displayed noticeable improvements regarding student’s pre-test and post-test results with 68% of students display improvements in their scores.

Authors:Opeyemi Samuel Williams; Razali Adul Hamid, Mohd Saidin Misnan Abstract: Within the focus of the final outcome of any construction activity is the realisation of minimal cost, timely delivery and quality oriented structure. Nevertheless, above all is the safe execution of the construction site activities, which is a matter of life, most especially lives of the operatives. The study focuses on the identification of the common types of accident, the level of occurrences, as well as the causes of the identified accidents. Through an extensive literature review, eighteen (18) different types of accident were identified, which were subsequently classified into seven (7) categories. Moreover, well-structured questionnaires were administered to construction participants, with the data analysed descriptively. The outcome revealed the four categories of frequently occurring accidents to be: contact with working tools, vehicle-related, slip and trip, and falls. Some crucial inclusions in the list of causes are failure of edge protection, safety standard violations, overloading of scaffold and crane, wrong placement of ladder, loss of control over body movement, failure in the designs, absence of warning signs, over speeding of vehicle, wrong selection of working tools, non-usage of personal protective equipment, improperly installed equipment, horseplay, and poor housekeeping. However, by exploring the accident process, recommendations based on the findings are put up. PubDate: Sun, 06 Jan 2019 08:35:54 +080
