This paper presents a Web-based information system for promoting the cascading utilisation of construction materials in order to mitigate the increasing environmental pressure by the construction industry. First, this paper points out me weaknesses of current waste material exchange systems. Then, a new approach is introduced to reuse demolished materials, by which the utilisation of demolished materials may be ascertained before the demolition is actually produced.. Information technologies, including web-based intelligent and distributed systems, are applied to actua1ise this approach. Finally, the development and implementation of the system is described in detail.

The construction activities of a contractor may physically take place in the home country or overseas, and the latter, particularly of a large company, has an increasing proportion with the globalisation. Globalisation of the construction industry and its market is a trend in every country, Which increases the opportunities of both international construction, and competition or collaboration with foreign construction companies. International construction project management is undertaken in a complicated circumstance, and requires a synthetic management approach. This research aims to establish a primary framework for the critical operational management in achieving international construction projects in a novel construction market.

The construction sector produces the facilities needed for a large majority of the production of goods and services, in which a sizeable proportion of Gross Domestic Product is generated. Recent trends in the globalisation of construction markets indicate that many countries consider construction industry competitiveness as crucial, and are working to increase construction productivity, in particular where the construction industries play an important role in their economic development. This paper first points out the research importance in international construction. Based on economic analyses of construction industries, a study is then carried out to focus on the economic sizes and benefits of the Chinese construction industry and to compare them with the Australian construction industry. Results derived from such an international construction comparison will assist in the Australian construction communities understanding the construction markets and industries in China and will benefit in international construction participation and cooperation.

This research is focused on developing a highly detailed understanding of current organisational interactions and information flows leading to a definition of the process model for the environment into which information and communication technology (ICT) applications will be placed. The authors of this paper propose a theoretical process model and the associated detailed information structure which reflects the complexity of information, stakeholder interaction and intellectual property concerns which are currently seen in the construction industry. This is being developed and tested against a field study renovation project. The field study project identifies information flows and interactions between stakeholders such as designers, project managers, clients, contractors, subcontractors and suppliers. The process model which is being established shows very high levels of complexity in dependencies and interdependencies between implicit and explicit information within the project design and construction teams. Without an understanding of these detailed and complex process interactions, proposals for the application of ICT to the construction industry will not reflect the requirements of those for whom they are being developed.

The construction industry worldwide is having problems attracting and retaining skilled workers. This study analyses a series of factors affecting job satisfaction of site-based construction professionals employed in medium to large scale metropolitan construction firms in Melbourne, Australia. The industry survey carried out identified salary as the strongest determinant of job satisfaction. However, many respondents reported being dissatisfied with pay levels when compared to other industries and the number of work hours expected. The greatest causes of dissatisfaction were related to difficulties in maintaining a work-life balance. The indicator "Variety, interest and challenge" was the most frequently cited positive aspect of a career in construction. Given the shortage of skilled construction workers in Australia, it is important for companies to maximise the retention of site-based construction professionals and ensure that key job satisfaction indicators are met.

Employee turnover has been identified as one of the principal causes of poor performance, low competitiveness and high technology loss in the construction industry. Construction managers normally acquire knowledge and skills in construction methods and management techniques on the basis of long-term practice, and their turnover can significantly impact on a construction organisation's survival and development. Therefore, there has been an increasing need to understand the major critical variables affecting the turnover of construction managers. The aims of this research were to determine these variables and use them to develop a quantitative turnover prediction model. A system framework was first developed to categorise all turnover variables into job satisfaction, organisation commitment and demographic variables and the turnover intention was measured in diverse directions. Based on an empirical study in Hubei province in China, the statistical results indicate that seven job satisfaction and organisational commitment variables dominate the turnover intentions of construction managers.

Water consumed directly by the construction industry is known to be of little importance. However, water consumed in the manufacture of goods and services required by construction may be significant in the context of a building's life cycle water requirements and the national water budget. This paper evaluates the significance of water embodied in the construction of individual buildings. To do this, an input-output-based hybrid embodied water analysis was undertaken on 17 Australian non-residential case studies. It was found that there is a considerable amount of water embodied in construction. The highest value was 20.1 kilolitres (kL)/m2 gross floor area (GFA), representing many times the enclosed volume of the building, and many years worth of operational water. The water required by the main construction process is minimal. However, the water embodied in building materials is considerable. These findings suggest that the selection of elements and materials has a great impact on a building's embodied water. This research allows the construction industry to evaluate design and construction in broad environmental terms to select options that might be cost neutral or possibly cost positive while retaining their environmental integrity. The research suggests policies focused on operational water consumption alone are inadequate.

As construction companies continue to explore foreign construction markets, various international construction projects are being undertaken in all corners of the world. In an international construction project with many unique and complicated characteristics, human resource management can play a significant role in promoting the efficient use of complex human resources. The aim of this paper is to establish a valid foundation for further research on measuring the impact of human resource management economically for international construction projects. The paper examines human resource management literature and identifies the application of the related management techniques to the construction industry. In addition, the paper uses the literature analysis to describe the nature of human resource management with particular reference to international construction projects. In particular, the research described in this paper identifies economic performance factors in the implementation human resource management in international construction projects. This paper also identifies the social effects of human resource management practices.

Very little research has been carried out regarding the risks and rewards of the international construction industry/market from an Australian perspective. A survey was sent to Australian based construction companies known to be operating internationally, to obtain their insights and perspectives on the risks and rewards of the international construction industry/market and international construction projects. Australian based companies have expanded their operations in order to benefit from inducements such as growth, profit and diversification. Continuing globalization and the openness of new markets has also provided significant opportunities to expand for Australian companies. Those Australian construction companies that have been operating abroad have been doing so for 20+ years in the Asia-Pacific and Australasian regions. This is significant as it shows that easily accessible markets are a stepping stone for further overseas expansion. The most commonly rated rewards for operating overseas were growth and profit; which matched the initial reason most companies chose to expand overseas. It was established that the ability to increase long term profitability through diversification was the biggest inducement for Australian construction companies expanding their operations overseas. When asked to rate the risks associated with international construction not one risk was rated significantly higher than the rest which supports the conclusion that the types of risks and rewards associated with each market rarely vary; only the severity and likelihood of occurrence. From an overall Australian perspective this research has established that the reasons and rewards for expanding overseas were the identical. Further that the risks associated with international construction were established as being different and varied depending on the market.

Deakin University’s School of Architecture and Building is renowned for producing graduates who possess relevant attributes that make them job ready for the building and construction industry. Graduate destination surveys indicate that in the last eight (8) years, 100% of all Infrastructure Logistics (Construction and Facility Management) course graduates found relevant employment. This success is a direct result of a curriculum that is responsive to industry needs alongside educational methodology that focuses on excellent teaching and research while seeking new ways of developing and delivering courses.

The Infrastructure Logistics course prepares graduates to successfully compete in today’s global job market, and allows them to showcase relevant knowledge and skills that are critical in seeking and sustaining employment. Traditionally, tailored resumes served this purpose; however, in many professional fields, professional portfolios are now becoming a more desirable way of providing a summary of relevant attributes alongside evidence of professional abilities.

Sustaining employment, appraisals, and applying for a promotion are often subject to adequate evidence of professional standards and growth. Professional bodies require records of contribution to Continuing Professional Development (CPD) schemes; and accrediting organisations require professionals applying for professional registration to provide documented evidence of their relevant experience and abilities. The Australian Institute of Project Management (AIPM 2007) requires candidates wanting to become Registered Project Managers (RegPM) to demonstrate their current work-based experience and competencies.

This paper reports on a teaching strategy adopted in the Project Management (PM) stream, offered as part of Infrastructure Logistic courses. The teaching strategy is based on a combination of constructivism theory of learning, problem and project based learning, and active learning. The strategy requires systematic reflection and conscious creation of documented evidence of PM attributes and competences in the form of a portfolio.

Preliminary results of action research monitoring the effectiveness of systematic reflection indicate that students respond very positively to the idea of professional journals and professional portfolios. Preliminary results also indicate that students accept reflection and conscious documentation of their achievements as an integral part of their study and future practice.

A major contributory factor to poor project performance in the construction industry is known to be the lack of integration and coordination between the different disciplines involved in various stages of the procurement process. Attempts by researchers to address this problem have met with limited success, as they have focused mainly on adapting integration techniques originally developed for use in the manufacturing industry. There is therefore a need to develop a detailed understanding of the fundamental sciences that underpin the problem of integrating the procurement process across the construction project life cycle. Presents and discusses a research model for addressing major methodological issues in the analysis of design/construction relationships.

Presents a case study of design management within an Australian design-construct organization on a large residential apartment project, with the purpose of identifying and analysing issues associated with the organization, responsibilities and stages of development in a typical design-construct project. Discusses the nature of introspection in the Australian construction industry, the shift in procurement methods, the design and build approach, whole life issues, the need for a design manager, and the role of the facilities manager. Profiles the case study organization and its contracts and procurement methods, before focusing on weaknesses in the company, the role of the project design development manager in leading the design team, managing the design consultants, and interacting and advising the developer in relation to design decisions. Suggests from the exercise that: the project manager should remain the overall project leader, manager and interface between design, cost, programme, buildability, construction and user requirements; the design manager should be responsible for issuing all documentation; and the design cost manager should be responsible for verifying that the design developed accords with project budgets, project brief and quality requirements in conjunction with the design manager.

International comparisons of construction industry performance are notoriously difficult. A recent comparative study, extensive in scope and using an innovative approach, is reviewed and questions raised regarding various aspects of the methodology adopted, the validity of the conclusions drawn and manner in which outcomes were reported. Particular areas of concern include the unequivocal statement of conclusions that are based on a small sample, and the use of data from that sample that are, in fact, no more than estimates of project performance. Attention is drawn to the limitations of the research reported and the reliability of the methods used, and the data gathered is examined.

Disputes have become an inherent feature of the construction industry. A plethora of studies have been undertaken to identify the causes of disputes so as to determine the most appropriate prevention and resolution strategies. While it is widely known what the main causes of dispute are, they still remain prevalent in the Australian construction industry. This is because there is a need to better understand the complexity and interplay between causal variables. Using data derived from the
literature a conceptual causal model of construction disputes is developed. The model identifies the key causal variables and pathogens that can contribute to disputes.
