In addition, the green roof was used as a plant growth medium for the soil element, and several interactions were created between the two strands. Malaysia has become the world's second-largest exporter of palm oil. However, the process of extracting the oil from the fruit will produce a byproduct known as palm oil clinker (POC) that will contribute to increasing landfill area. Since the POC is a waste material, the potential of chemical reaction to the plant development and runoff quality needs to be carried out. Therefore, this study investigates the potential of using palm oil clinker as a drainage layer in green roof systems in terms of plant development and runoff quality. The extensive green roof (EGR) specimens were prepared and the POC was used to replace the conventional drainage layer in the green roof system. In addition, physical and chemical tests were carried out in the laboratory to ascertain the result including the turbidity, total suspended solids (TSS), pH, and chemical oxygen demand (COD) test. Based on the results, although the COD and TSS are high, it is still within an acceptable range set by National Water Quality Standard (NWQS). The data analysed by using the quantitative data analysis techniques have shown that the POC has a good potential to be used as a drainage layer in the green roof system.","PeriodicalId":10603,"journal":{"name":"Construction Technologies and Architecture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82763020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The worst damage occurred in Meuraxa, Kuta Raja, Syiah Kuala and Kuta Alam sub-districts, because the location faced directly to the Malacca Strait. The Rehabilitation and reconstruction activities have rebuilt the houses in the same spot area. More over the house models have not heeded the risk of tsunami. This study aims to identify the effect of model and material house toward the tsunami risk in Banda Aceh city. The research method used questionnaires that were distributed to 30 respondents from the expert. Data processing and analyzing used Structural Equation Model-Partial Least Square (Smarth-PLS) through standardized loading factor and composite reliability. The model shows that the variation in the value of the material and house model variables on tsunami disaster risk is moderate. Based on the results of the bootstrap calculation, all indicators have a significant effect on tsunami hazard except the type of non-permanent house structure. The results of the path coefficient show that a house with a stilt model has a significant effect on the level of tsunami disaster risk, while the house material on the walls of the house should use fabricated materials. To sum up, the construction of houses in tsunami risk areas should consider the model of houses on stilts with reinforced concrete materials. Stilt houses provide space for tsunami flows to avoid turbulence, and with a structure of house is resistance according building code.","PeriodicalId":10603,"journal":{"name":"Construction Technologies and Architecture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89276856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Without building inspections, maintenance work will be overwhelming and will result in losses in terms of time and money incurred. To determine the defect, visual inspection will be conducted as early phase of building inspection. In Malaysia, inspection on exterior enclosure of structures not usually apply because of the high cost of doing inspection and it takes a long time too. Furthermore, visual inspection usually carries out with the aid of binoculars and cameras for examining eyes. In general, the buildings that known as a high-rise building is a building that has the structure roughly seven floor or more. At such altitude, any defects and damage to the building difficult to be observe with the naked eye. Hence, the aim of this study is to propose Unmanned Aerial Vehicle (UAV) as tool that used to inspecting defect on high-rise building. Building that being choose is Urban Transformation Centre (UTC) Malacca that located at Jalan Hang Tuah, 75300 Malacca. The data collected will be analyzed using Condition Survey Protocol (CSP1 Matrix) to obtain an overall rating of the building’s condition. The process involved in this study are site visit, planning and preparation before the flight, data collection using UAV, image processing and analyzing data from image. The results of analysis, 331 defects have been identified and documented suffer from defects or faults such as cracking, scaling, spalling, peeling paint, expansion joint and mould. All defects information obtained using UAV visual inspection can help the UTC Malacca maintenance to do maintenance work. The overall condition of this building structure is 6.6, where the overall performance of the building is average.","PeriodicalId":10603,"journal":{"name":"Construction Technologies and Architecture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90576865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researchers in the field of advanced construction materials are increasingly paying attention to kenaf fibers as a \"green\" material because of their possible application in composites to advance sustainable development. However, there has been no attempt of scientometric analysis to investigate the comprehensive understanding of the present state of applications of kenaf fibers in reinforced concrete. The study aims to perform a bibliometric analysis of the existing kenaf fibers reinforced concrete literature and to provide a picture of the research status during the last ten years from 2013 to September 2022. There were 303 articles extracted from the Scopus database. The “VOSviewer” tool was employed to visualize the literature containing the most active scientific journals, countries, and highly used keywords in the field of fibers reinforced concrete. The outcomes showed that “Hybrid Composites”, “Impact Strength”, “Water Absorption”, “Scanning Electron Microscopy”, “Polypropylenes” and “Polymer Composite” have recently emerged as themes related to the applications of KFRC, and grabbed the interest of academics, may also offer future research opportunities. Additionally, according to the frequency of the keywords used, three important research domains associated with kenaf fibers within the concrete in the construction materials field have been identified, including “Mechanical Properties”, “Fiber Reinforced Plastics”, and “Tensile Strength”. Furthermore, the recent studies on the impact of kenaf fiber utilization on the structural performance of reinforced concrete are reviewed. Accordingly, the explanations related to research findings, suggestions for future studies have been provided on the incorporation of kenaf fibers reinforced concrete in civil engineering applications.","PeriodicalId":10603,"journal":{"name":"Construction Technologies and Architecture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74823731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While Basalt fiber reinforced polymers (BFRP) have shown improved mechanical properties and durability performance compared to conventional steel, it is not immune to degradation and corrosion when subjected to harsh environments. As such, significant studies have been conducted to simulate the mechanical properties of BFRP bars under degradation when subject to different hostile substances. However, there is no standardized conclusion for the performance of BFRP under an acidic environment and in-depth microstructure evaluation as the degradation of BFRP is influenced by myriad factors. This study aimed to produce a Response Surface Methodology (RSM) model to study the effect of pH, temperature, and immersion time on the tensile strength and elastic modulus. Data from existing literature involving acid emersion of BFRP were collected and modelled using RSM to present an overview of the degradation behavior of BFRP. In addition, a synthesis of the microstructure of BFRP reinforcing bars exposed to the acidic environment was evaluated by referring to SEM and EDX. It was concluded that the tensile strength loss due to corrosion was affected by temperature and immersion time in a linear function. On the other hand, tensile strength drop occurred exponentially as an acid with higher pH was used. Hence, the paper revealed the influence of various factors on the corrosion rate of the BFRP rebar.","PeriodicalId":10603,"journal":{"name":"Construction Technologies and Architecture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78264026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These changes not only often occur in the implementation (build) phase of a construction project, but it also happens in the planning (design) phase. In general, dealing with such uncertain circumstances means to have the possibility for failure in achieving the goals of a project. Even though changes and adjustments are common in this sector, it nevertheless will bring risks to the construction works. For example, the time, costs, and quality. Hence, a preventive system is needed with which can minimise the risks that may arise during the project activities. The objective of this research is to identify the caused factors of the risks on the construction business, and that to further suggest the applicable model as the preventive action of the risks. This study began with a detail review to seven risk indicators; Labour Risk (X1), Contractual Risk (X2), Human Resources Risk (X3), Design and Technology Risk (X4), Material and Tool Risk (X5), Implementation Risk (X6), and Force Majeure Risk (X7). This research was developed further using questionnaires and expert validation as the primary data, which furthermore analysed using analysis factors, descriptive analysis, and probability impact matric in order to determine the level of the risks. The risk level analysis resulted three variables as the top event (dominant risk), which are X1, X3 and X4. These findings were then advanced following Bowtie diagram and scenario analysis, hence suggested a modelling that described possible preventive and corrective strategies. Both the Bowtie diagram and scenario analysis are not only helpful as the guidance and warning, but also practical for the construction practitioners in managing the risk management and decision making for the construction project.","PeriodicalId":10603,"journal":{"name":"Construction Technologies and Architecture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82287947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
