    Get PDF
    Purpose: The exploitation of smart technologies such as, Radio Frequency Identification (RFID) and Building Information Modelling (BIM) for tracking and archiving the properties of structural components, is an innovative disruption in the construction sector. It could stimulate reuse of construction components, rather than their wastage addressing a serious pressing problem. Methods: This study explores the potential of smart technologies to facilitate construction components reuse, and develops a guidance list for promoting their redistribution back to the supply chain. A preliminary assessment of the strengths, weaknesses, opportunities and threats of the RFID technology is presented in order to depict its current and future potential in promoting construction components’ sustainable lifecycle management, and in capturing and creating value. Results: For both RFID and BIM technologies to operate successfully, the right amount and flow of information at each stage of the design-construction-deconstruction-reuse-disposal process is a prerequisite. Although a number of limitations related to the technical operability and recycling of RFID tags currently withhold its roll-out, technological innovation may provide solutions for the future, enabling it to become mainstream. Conclusions: the use of RFID in the construction sector can create the right conditions for the development of new business models based on the reuse and lifecycle management of components, unlocking multiple technical, environmental, economic, and social benefits. With technological innovation enhancing the capabilities of RFID, and with policy interventions controlling and managing its uptake at all stages of the supply chain, its use as a construction components reuse enabler might soon become realised

    Kualiti Persekitaran Dalaman atau Indoor Environmental Quality (IEQ) merupakan komponen penting dalam konteks bangunan mesra alam yang akan menentukan tahap kualiti penghuni di dalam sesebuah bangunan. Secara purata dianggarkan 80% kehidupan seharian manusia adalah berada di dalam bangunan. Ketidakseimbangan IEQ menyumbang kepada Sindrom Bangunan Sakit (Sick Building Syndrome) sekali gus memberi kesan kepada produktiviti para penghuni juga kepada struktur bangunan. Sehubungan itu, kajian ini dilaksanakan untuk mengenal pasti tahap kesedaran pihak pengurusan harta dan fasiliti di Institusi Pengajian Tinggi Awam (IPTA) terhadap IEQ dalam konteks bangunan akademik. Kajian ini juga bertujuan untuk mengukur tahap IEQ dan tahap kepuasan pengguna dalam bangunan akademik di IPTA. Kajian ini melibatkan bangunan akademik di 20 IPTA di Malaysia. Metodologi kajian ini menggunakan pendekatan kualitatif, kajian saintifik dan juga pendekatan secara kuantitatif. Pendekatan Kualitatif digunakan bagi menilai tahap kesedaran pihak pengurusan harta dan fasiliti IPTA melalui proses temubual yang melibatkan 20 orang responden. Manakala pendekatan kedua adalah melalui kajian saintifik ke atas bangunan akademik yang memfokuskan kepada pengukuran elemen keselesaan terma, keselesaan bunyi, kualiti udara dalaman dan pencahayaan. Hasil pengukuran elemen tersebut dibandingkan dengan piawaian dari Malaysia Standard (MS 1525;2007) dan UNESCO. Bagi setiap IPTA, lima buah bilik kuliah dijadikan sampel dengan tiga kali bacaan setiap hari selama dua hari diperolehi bagi mendapatkan bacaan purata. Seterusnya, melalui pendekatan kuantitatif, data yang diperolehi melalui kaji selidik melibatkan 500 responden dan dianalisis menggunakan perisian Statistical Package for Social Science (SPSS). Hasil kajian menunjukkan kesedaran para pengurus harta dan fasililti di IPTA terhadap IEQ adalah baik tetapi masih ada beberapa kelemahan yang perlu ditambahbaik. Hasil ujian saintifik yang diperolehi menunjukkan bacaan bagi suhu dalaman, hanya UniSZA, UTHM dan UniMAS yang menepati piawaian, manakala bagi pencahayaan, UM, UIAM, UPSI, USM, UniSZA, UTM, UTHM, UTeM, UMS dan UniMAS berada di bawah tahap piawaian ditetapkan. Bagi keamatan bunyi, hanya UM, UPM, UPSI, USM dan UniMAP yang menunjukkan bacaan pada piawaian ditetapkan. Keseluruhannya menunjukkan bacaan berada pada tahap yang sederhana dan masih lagi memerlukan pernambahbaikan. Kajian ini turut mempamerkan bacaan purata bagi setiap elemen IEQ bagi bangunan akademik seluruh IPTA. Penemuan hasil kajian ini dijangka dapat membantu pihak pengurusan harta dan fasiliti IPTA dalam usaha menambahbaik tahap IEQ dalam bangunan akademik di kampus universiti sekaligus dapat meningkatkan tahap pengurusan fasiliti dalam mencapai tahap kelestarian kampus IPTA di Malaysia

    Intelligent Materials Tracking System for Construction Projects Management

    Get PDF
    An essential factor adversely affecting the performance of construction projects is the improper handling of materials during site activities. In addition, paper-based reports are mostly used to record and exchange information related to the material components within the supply chain, which is problematic and inefficient. Generally, technologies (such as wireless systems and RFID) are not being adequately used to overcome human errors and are not well integrated with project management systems to make tracking and management of materials easier and faster. Findings from a literature review and surveys showed that there is a lack of positive examples of such tools having been used effectively. Therefore, this research focused on the development of a materials tracking system that integrates RFID-based materials management with resources modelling to improve on-site materials tracking. Rapid prototyping was used to develop the system and testing of the system was carried out to examine the functionality and working appropriately. The proposed system is intended to promote the employment of RFID for automatic materials tracking with integration of resource modelling (Microsoft (R) Office Project) in the project management system in order to establish which of the tagged components are required resources for certain project tasks. In conclusion, the system provides an automatic and easy tracking method for managing materials during materials delivery and inventory management processes in construction projects

    No full text
    The recycling of plastics tends to lag behind other packaging materials. The research investigates opportunities to improve the capture of valuable packaging polymers and to preserve their specification during recycle operations, thus increasing second user opportunity. The legislative and policy drivers on the sustainable use of plastics are described and discussed with particular reference to achieving sustainability, reuse and recycle of healthcare packaging materials. Four strategic methods of achieving improvements in sustainability, reuse and recycle are developed to represent aspects of sorting of materials, collection of recyclables, replacement of unsustainable packaging materials and measurement of the environmental impacts of packaging and changes in packaging, using examples of packaging from GlaxoSmithKline consumer healthcare and medical products. The use of radio frequency identification methodology as a means of separating high quality plastics and individual reusable devices from mixed waste streams has been developed and trialled under simulated materials recycling and separation conditions. The use of Reverse Vending Machines (RVM's) designed to capture high quality polyethylene terephthalate polymers is described along with results of successful trials on this method of capture in the out of home consumption sector. Recovered material is suitable for reuse in food grade applications after reprocessing. A novel biodegradable packaging material has been successfully developed from sources of green waste as an alternative to existing polymer packaging materials for transport of vaccines, and provides results that are extendable to the replacement of other types of packaging over a wide range of consumer goods. The material also offers intangible benefits to a business in terms of claims that can be made within a corporate social responsibility (CSR) report. Life cycle analysis methodologies have been used to illustrate the environmental benefits that can be achieved by reuse of polypropylene as an example of a widely used packaging polymer with potential for reuse in other industrial sectors. The implications of the results obtained in this work should be of value in the future eco-design of polymer products designed to make end-of-life recovery and recycle more efficient and environmentally beneficial
