A framework for material management in the building demolition industry

Conventional mechanical building demolition produces numerous solid wastes, most of which are sent to landfill directly and severely degrade the living environment. Just-in-time building demolition has been developed recently with a management strategy to facilitate waste reuse. Procurement management plays a significant role in just-in-time building demolition. In particular, the demolition tendering selection needs to consider contractors' environmental performance in addition to project costs. Moreover, the flow of building materials in a demolition project may be regarded as a supply chain involving the building owner, demolition contractor and material demanders. This paper develops a framework for salvaged materials management in the emerging demolition industry. The research is to promote the recycling and reuse of building demolition materials in order to achieve better environmental and financial performance for building demolition projects.

MRP-production planning in agile manufacturing

The research studied a production planning problem in a manufacturing firm. Some production planning software was developed that enabled the efficient and rapid reproduction of an optimum production forecast. Not only was the production cost reduced but a significant length of planning time cn be saved using the software.

Decision support tool for production planning of a machining line

A decision support tool for production planning was developed to perform the difficult and time consuming task of allocating resources within the industrial partner's machining line, consisting of identical Computerized Numerically Controlled machines. The production-planning tool identified significant labour savings in a number of the industrial partner's production plans.

An analysis of factors influencing waste minimisation and use of recycled materials for the construction of residential buildings

Residential building construction activities, whether it is new build, repair or maintenance, consumes a large amount of natural resources. This has a negative impact on the environment in the form depleting natural resources, increasing waste production and pollution. Previous research has identified the benefits of preventing or reducing material waste, mainly in terms of the limited available space for waste disposal, and escalating costs associated with landfills, waste management and disposal and their impact on a  building company's profitability. There has however been little development internationally of innovative waste management strategies aimed at reducing the resource requirement of the construction process. The authors contend that embodied energy is a useful indicator of resource value. Using data provided by a regional high-volume residential builder in the State of Victoria, Australia, this paper identifies the various types of waste that are generated from the construction of a typical standard house. It was found that in this particular case, wasted amounts of materials were less than those found previously by others for cases in capital cities (5-10 per cent), suggesting that waste minimisation strategies are successfully being implemented. Cost and embodied energy savings from using materials with recycled content are potentially more beneficial in terms of embodied energy and resource depletion than waste minimisation strategies.

Promoting the reuse and recycling of building demolition materials

The demolition of constructed structures has earned a negative reputation for the construction industry due to the enormous amount of waste that is sent to landfills. Demolition waste reuse and recycling is, therefore, significant; it is a new and illustrative perspective on demolition waste management from the viewpoint of the building material lifecycle. It is discovered that demolition waste reuse and recycling plays important roles in value transformation for building material lifecycle, local economics,
sustainable environment and nature resource conservation. In this research article, the authors aim to pinpoint demolition waste management in the lifecycle of building materials, and to examine various economic and environmental aspects of demolition waste reuse and recycling. In addition, the barriers, limitations and solutions for improving the implementation of demolition waste reuse and recycling are discussed in the article.

Development of a multimedia data acquisition toolkit and its application for exchanging demolished materials

In the development of a web-based information system such as a demolition material management system, a great amount of diversified information on projects should be acquired from particular users located with various computer platforms. This issue is difficult to handle using the limited HTTP form submission, which could lead to inaccuracy of the information and inefficiency of the whole system. This paper describes a web-based graphical user interfaced, dynamic and distributed multimedia data acquisition mechanism, which accepts users' drawings and retrieval information from the canvas and stores the multimedia data on a server for further usages. Furthermore, techniques and principles needed to construct such a multimedia data acquisition tool are addressed in detail. The application of this distributed multimedia tool in developing a web-based demolition material management system is also described.

Web enabled just-in-time salvaged material management for demolition projects

The demolition activities of buildings produce numerous environmental pressures as a large proportion of demolition waste materials are sent to landfill directly in many projects. Web-based waste exchange systems could provide right solutions for releasing these pressures. Because the approaches adopted in current waste exchange systems are inefficient, these systems cannot generate waste exchange, not achieving their final goal, environmental protection. The Just-in-time (JIT) philosophy has been applied in the manufacture industry for decades and it is proven to be effective to eliminate or minimise inventory during production. This research aims to adopt the JIT philosophy into a demolition project management informapon system so that the system is more efficient in handling waste exchange. The system structure, key components and Just-in-time adoption are proposed and identified. Finally, a proto typed system is demonstrated.

Salvage material logistics management for building demolition project

Building demolition imposes substantial environmental impacts. In particular, large amount of demolition wastes are disposed to landfills. A solution to ease the situation is to maximally reuse and recycle waste building material. Management philosophies such as Just-in-time are applied into demolition project management in order to promote reuse and recycling of demolition wastes. Transportation logistics, widely applied in the manufacturing industry, is ideal to be adopted into demolition projects to optimise waste material production, inventorying, and transportation. In particular, it enables right types and amounts of dismantled building materials to be transferred to right location, and at right time, as required by material demanders. Consequently, waste reuse and recycling can be facilitated. Furthermore, logistics management helps the demolition project team to reduce cost, shorten project duration, and satisfy material demanders. Transportation planning concerns thorough preparation technically and managerially on the demolition site for transportation activities. Information exchange is playing a significant role in delivering and sharing information among project participants, including building owner, demolition project team, potential material demanders, and transporters. This research paper aims to identify the role of transportation logistics in a building demolition project and to analyse inventory control, transportation, and various technical aspects of logistic management for demolition wastes.

International and culturally inclusive curricula-an engineering management unit audit case study

SEB421 Strategic Issues in Engineering is a final-year engineering management study unit at Deakin University in which the enrolled student population has grown to include significant numbers of international students. Given this change, it was considered timely to conduct a review of the unit, with regard to principles of international and culturally inclusive curricula. Despite the historically white Anglo-Saxon male culture of engineering education in Australia, there are a wide range of international and cultural aspects related to engineering education. A review of the literature reveals a diversity of interpretations of 'internationalisation' and 'cultural inclusiveness'. From a pragmatic perspective, it is noted that organisational policy can provide guidance for academic staff seeking to make courses more inclusive. From a review of the literature and relevant university policies, a list of 'international and culturally inclusive curricula' guidelines for engineering management education was developed. Comparing a prior audit of SEB421 with these guidelines revealed progress on international and culturally inclusive curricula, but identified opportunities for improvement. The guidelines were applied to the curriculum/syllabus, content/study materials, conduct and assessment of the unit, to identify further opportunities for improvement. A plan for improvement of the unit and an associated timetable for this work were developed. It was noted that some changes can be made immediately, while others are contingent upon the timetable imposed by university systems. It was further noted that issues of change within a single study unit intersect with wider issues of program curriculum, and, while pilot activities can provide a start, eventually the wider issue of international and culturally inclusive curricula across the entire undergraduate engineering program needs to be considered.

Categorisation of knowledge management processes in the development of sustainable enterprises

Sustainable development is a growing area of interest in organisations. Particularly those that have large energy demands for processing, use dwindling raw materials or produce a great deal of waste through production. Knowing those processes that can contribute to making an organisation more sustainable provides a great advantage both in terms of project implementation success and in measurable Triple Bottom Line returns.

In previous research we identified that many of the Information Technology processes used to assist organisations in developing sustainable practices were more clearly suited as Knowledge Management processes (Van Der Meer and Sinnappan, 2008), however less empirical study has been done to categorise them meaningfully.

In this study we have taken these Knowledge Management processes and categorised them according to the sustainable development practice where we identify they can be of service based on Waage et al (2003). Through this we are hoping to develop a framework for organisations to determine what Knowledge Management processes are needed to achieve the particular sustainable development. We may also be able to judge what steps an organisation needs to take to develop further sustainable practices in other areas.

Development of a framework for knowledge management tools in sustainable development would assist industries in determining the best processes for these sustainable projects. This framework also contributes to the body of knowledge on sustainable development and Information Technology.

Effectiveness of a community-based osteoporosis education and self-management course : a wait list controlled trial

Summary : Osteoporosis is an increasing burden on individuals and health resources. The Osteoporosis Prevention and Self-Management Course (OPSMC) was designed to assist individuals to prevent and manage osteoporosis; however, it had not been evaluated in an Australian setting. This randomised controlled trial showed that the course increased osteoporosis knowledge.
Introduction and hypothesis : Osteoporosis is a major and growing public health concern. An OPSMC was designed to provide individuals with information and skills to prevent or manage osteoporosis, but its effectiveness has not previously been evaluated. This study aimed to determine whether OPSMC attendance improved osteoporosis knowledge, self-efficacy, self-management skills or behaviour.
Materials and methods : Using a wait list randomised controlled trial design, 198 people (92% female) recruited from the community and aged over 40 (mean age = 63) were randomised into control (n = 95) and intervention (n = 103) groups. The OPSMC consists of four weekly sessions which run for 2 h and are led by two facilitators. The primary outcome were osteoporosis knowledge, health-directed behaviour, self-monitoring and insight and self-efficacy.
Results : The groups were comparable at baseline. At 6-week follow-up, the intervention group showed a significant increase in osteoporosis knowledge compared with the control group; mean change 3.5 (p < 0.001) on a measure of 0–20. The intervention group also demonstrated a larger increase in health-directed behaviour, mean change 0.16 (p < 0.05), on a measure of 0–6.
Conclusion : The results indicate that the OPSMC is an effective intervention for improving understanding of osteoporosis and some aspects of behaviour in the short term.

Evolution of moisture management behavior of high-wicking 3D warp knitted spacer fabrics

Moisture management behavior is a vital factor in evaluating thermal and physiological comfort of functional textiles. This research work studies functional 3 dimensional (3D) warp knitted spacer fabrics containing high-wicking materials characterized by their profiled cross section. These spacer fabrics can be used for protective vest to absorb a user’s sweat, to reduce the humidity and improve user’s thermal comfort. For this reason, different 3D warp knitted spacer fabrics were produced with functional fiber yarns in the back layer of the fabric (close to the body) and polyester in the front and middle layers (outer surface). Comfort properties such as air and water vapor permeability and wicking and other moisture management properties (MMP) of different fabric samples were measured. It is demonstrated that by using profiled fibers such as Coolmax fiber, moisture management properties of spacer fabrics can be improved, enabling them to be use as a snug-fitting shirt worn under protective vests with improved comfort.

Exploring distributed leadership for the quality management of online learning environments

Online learning environments (OLEs) are complex information technology (IT) systems that intersect with many areas of university organisation. Distributed models of leadership have been proposed as appropriate for the good governance of OLEs. Based on theoretical and empirical research, a group of Australian universities proposed a framework for the quality management of OLEs, and sought to validate the model via a survey of Australasian university representatives with OLE leadership responsibility. For the framework elements: Planning and Resourcing were rated most important; Organisational structure was rated least important; Technologies were rated low in importance and high in satisfaction; Resourcing and Evaluation were rated low in satisfaction; and Resourcing had the highest rating of importance coupled with low satisfaction. Considering distributed leadership in their institution, respondents reported that the organisational alignments represented by 'official' reporting and peer relationships were significantly more important and more effective than the organisational alignments linking the formal and informal leaders. From a range of desirable characteristics of distributed leadership, 'continuity and sustainability' received the highest rating of importance and a low rating of 'in evidence' - there are concerns about the sustainability of distributed leadership for the governance of OLEs in universities.
