Catalysing design principles through the dreaming of sustainable subtropical cityscapes : the collaborative construction of new place identities

This paper addresses the question of how to open up pathways and build capacity to facilitate the movement towards sustainable sub-tropical cities. The focus is on outlining a collaborative planning and co-design process that can help catalyse the emergence of sustainable place-habitats and so re-weave and colour anew the tapestry of our sub-tropical cities. Cities are portrayed as self-organising complex adaptive system phenomena, being constantly re-shaped by local and global social-political, environmental, cultural and economic forces as well as planning regimes. While constructing a sustainable city is at essence a design process incorporating new sustainable practices and legislation to reinforce their use, these steps are necessary but not sufficient. Sustainable sub-tropical city-making could be re-thought as a dreaming-re-storying process. This paper explores a new co-design process, which can channel collaborative efforts around re-inventing sustainable place-habitats across the cityscape. A further outcome of this co-design process is the alignment of the emergent design principles and planning actions that can trigger the re-storying of a new sustainable sub-tropical city. Besides a new co-design process, we also advocate the building of sub-tropical city learning networks to facilitate the cross-fertilization for Dreaming sustainable sub-tropical cities.

The construction contract bidder homogeneity assumption : an empirical test

This paper describes an empirical study to test the proposition that all construction contract bidders are homogeneous ie. they can be treated as behaving collectively in an identical (statistical) manner. Examination of previous analyses of bidding data reveals a flaw in the method of standardising bids across different size contracts and a new procedure is proposed which involves the estimation of a contract datum. Three independent sets of bidding data were then subjected to this procedure and estimates of the necessary distributional parameters obtained. These were then tested against the bidder homogeneity assumption resulting in the conclusion that the assumption may be appropriate for a three parameter log-normal shape, but not for scale and location.

Which estimating technique?

This paper presents a unified view of the relationship between (1) quantity and (2) price generating mechanisms in estimating individual prime construction costs/prices. A brief review of quantity generating techniques is provided with particular emphasis on experientially based assumptive approaches and this is compared with the level of pricing data available for the quantities generated in terms of reliability of the ensuing prime cost estimates. It is argued that there is a tradeoff between the reliability of quantity items and reliability of rates. Thus it is shown that the level of quantity generation is optimised by maximising the joint reliability function of the quantity items and their associated rates. Some thoughts on how this joint reliability function can be evaluated and quantified follow. The application of these ideas is described within the overall strategy of the estimator's decision - "Which estimating technique shall I use for a given level of contract information? - and a case is made for the computer generation of estimates by several methods, with an indication of the reliability of each estimate, the ultimate choice of estimate being left to the estimator concerned. Finally, the potential for the development of automatic estimating systems within this framework is examined.

The distribution of construction project bids

This paper describes an analysis of construction project bids to determine (a) the global distribution and (b) factors influencing the distribution of bids. The global distribution of bids was found, by using a battery of ll test statistics, to be approximated by a three-parameter log normal distribution. No global spread parameter was found. A multivariate analysis revealed the year of tender to be the major influencing factor. Consideration of the construction order, tender price and output indices lead to the conclusion that distributional spread reflected the degree of difference in pricing policies between bidders and the skewness of the distributions reflected the degree of competition. The paper concludes with a tentative model of the causal relationships between the factors and distributional characteristics involved.

An expert system for the strategic planning of construction projects

This paper describes the instigation and development of an expert system to aid in the strategic planning of construction projects. The paper consists of four parts - the origin of the project, the development of the concepts needed for the proposed system, the building of the system itself, and assessment of its performance. The origin of the project is outlined starting with the Japanese commitment to 5th generation computing together with the increasing local reaction to theory based prescriptive research in the field. The subsequent development of activities via the Alvey Commission and the RICS in conjunction with Salford University are traced culminating in the proposal and execution of the first major expert system to be built for the UK construction industry, subsequently recognised as one of the most successful of the expert system projects commissioned under the Alvey programme

Factors affecting marketing decision making with an ethical content : collusive tendering in the construction contract market

Reports of immoral marketing practices i n the construction industry attract political, media and public but not much academic interest. This paper adopts a behavioural perspective and proposes a model for applying marketing ethics concepts and methods in the study of collusion in the construction contract market. An extensive multidisciplinary review of existing literature identified a lack of adequate conceptualisation of the mechanisms and decision making factors of collusive tendering. The process of developing the model is detailed in this paper. The objectives and methodology of the research project that tested the model are also outlined. The paper concludes with a brief note on the contributions and application of the proposed model.

A new research agenda into community-based protest in construction

Many countries face enormous development challenges in adapting to demographic change, urbanisation and emerging issues such as housing affordability and climate change. These challenges are best resolved in consultation with communities rather than in conflict with them. A rich tradition of research and intellectual frameworks exist in the fields of urban geography and planning to understand and manage community concerns during the pre-development approval stages of new projects. However current theoretical frameworks are inadequate in construction management and a new research agenda is needed to develop conceptual frameworks to guide thinking about the role of communities in the construction process. By discussing the components of such a model, it is concluded that this would require a fundamental shift in thinking which challenges traditional structuralist paradigms. A new constructivist paradigm is presented that conceives community consultation as a negotiation process which does not stop at the pre-development planning stages but which continues over the entire life of a project.

The impact of construction organisations’ learning capabilities on collaborative projects

Dynamic capability theory asserts that the learning capabilities of construction organisations influence the degree to which value-for-money (VfM) is achieved on collaborative projects. However, there has been little study conducted to verify this relationship. The evidence is particularly limited within the empirical context of infrastructure delivery in Australia. Primarily drawing on the theoretical perspectives of the resource-based view of the firm (e.g. Barney 1991), dynamic capabilities (e.g. Helfat et al. 2007), absorptive capacity (e.g. Lane et al. 2006) and knowledge management (e.g. Nonaka 1994), this paper conceptualises learning capability as a knowledge-based dynamic capability. Learning capability builds on the micro-foundations of high-order learning routines, which are deliberately developed by construction organisations for managing collaborative projects. Based on this conceptualisation of learning capability, an exploratory case study was conducted. The study investigated the operational and higher-order learning routines adopted by a project alliance team to successfully achieve VfM. The case study demonstrated that the learning routines of the alliance project were developed and modified by the continual joint learning activities of participant organisations. Project-level learning routines were found to significantly influence the development of organisational-level learning routines. In turn, the learning outcomes generated from the alliance project appeared to significantly influence the development of project management routines and contractual arrangements applied by the participant organisations in subsequent collaborative projects. The case study findings imply that the higher-order learning routines that underpin the learning capability of construction organisations have the potential to influence the VfM achieved on both current and future collaborative projects.

Effective community engagement for project success : building professionals as active participants during the construction phase of projects

Growing community concerns about the ecological, social, cultural and economic impact of housing and urban projects poses new challenges for those who have to deliver them. It is important that these concerns are addressed as part of the community engagement processes on projects. Community engagement is traditionally perceived as the purview of planners and disconnected from the building construction process. This is despite most project approval processes mandating on-going community engagement over the project’s entire lifetime. There is evidence that point to a culture of ambiguity and ambivalence among building professionals about their roles, responsibilities and expectations of community engagement during the construction phase of projects. This has contributed to a culture of distrust between communities and the construction industry. There is a clear need to build capacity among building professionals to empower them as active participants in community engagement processes which can promote better project outcomes and minimise delays and conflicts. This paper describes a process that utilises the Theory of Planned Behaviour as a framework to equip building professionals with the skills they need to engage effectively with local communities during the construction phase of projects.

Knowledge management practices in construction : Evidence from Hong Kong

The acquisition and management of knowledge is the dominant source of organisational com-petitive advantage. As innovation processes in the management and procurement of construc-tion activities are becoming increasingly interactive, knowledge management (KM) has been widely recognised by construction organisations as an essential tool to be employed when dealing with growing complexity and cost of projects as well as increasing client demands. KM requires deliberate efforts by an organisation to maximise its performance through the acquisition, dissemination and leveraging of the organisation’s intellectual assets. The Hong Kong (HK) construction market has been described as one of the most open and globally competitive. This paper reports on KM practices within the HK construction industry, and through the analysis of a self-administered questionnaire survey, reveals managers’ opinions of the formal and informal KM practices that could be used to manage the flow of knowledge, and identifies the level of implementation within their organisations. The differences between managers’ perception and the actual state of implementation – as reported by the same man-agers – are statistically examined. The analysis leads to better understanding of how HK con-struction professionals currently manage organisational knowledge, and what areas for poten-tial improvement exist.

Empirical analysis of knowledge management activities in construction organisations

Knowledge is a commodity. It is a by-product of learning that involves the creation, sharing, processing and possible use of information in the mind of an individual. Knowledge management (KM) is, therefore, concerned with the effective implementation of such activities within the organisation. It is simply the process of leveraging organisational knowledge to deliver a long-term competitive advantage. This paper presents the results of an empirical research investigation into the interaction between different KM activities within the context of construction contracting organisations. The different KM activities include: responsiveness to the knowledge of business environment, knowledge acquisition, knowledge dissemination, and knowledge application. A questionnaire survey was administered to investigate the opinions of construction professionals regarding the intensity of activities currently implemented by their organisations to facilitate knowledge capturing, sharing and application. A total of 149 responses were then used to statistically examine the inter-relationships between the different KM activities as practised by contracting organisations in Hong Kong. The paper presents and discusses the survey findings and proposes recommendations for improving the effectiveness of current KM practices.

Impacts of foreign direct investment on China’s construction industry

China’s national construction industry is now preparing to face the challenges, and to seize the opportunities, resulting from China’s entry to the World Trade Organisation (WTO). With the foreign direct investment (FDI) hitting a record high of around US$52.7 billion in 2002, China is believed to have now surpassed the USA as the world’s favorite destination for foreign investment. This fact, coupled with the huge potential for infrastructure development, indicates that the relatively large proportion of FDI flowing into the national construction industry will continue to increase in the foreseeable future. Positive aspects of FDI flowing will definitely help forging new industrial capabilities for China’s construction industry, thus helping it to achieve the ambitious strategic targets set by the Government for exporting construction goods and services. To shed some light on the position of the national industry in the global economy, this paper briefly presents the current international standing of China’s construction industry and qualitatively appraises potential positive influences of, and challenges associated with, FDI on the national industry.
