Housing supply chain model for innovation: research report

The aim of this research is to undertake a case study analysis of successful delivery of an innovation to the Australian housing construction industry. This study is conducted on the “innovator group”; that is, the group that created the idea of an innovation for the housing sector and then were intimately involved in creation, development and diffusion. It is apparent that there were key players involved in this process which are representative of various organisations along the supply chain – designer, developer, subcontractor and supplier. Much rhetoric states that integration of the supply chain actors will solve construction problems, however, in reality we know little beyond this in the Australian context as there has been little research conducted previously. This study will examine in detail the process undertaken by this particular group to deliver an innovation to the housing sector which required an integrated construction supply chain model. This report was published by the Australian Housing Supply Chain Alliance and written by Professor Kerry London, School of Property, Construction and Project Management, RMIT University with Research Fellow, Jessica Siva

Construction Supply Chain Economics

This is the first comprehensive investigation of the industrial sourcing and procurement practices throughout sixty-eight construction industry supply channels across seven major commodity sectors at all levels. London presents real-world case studies to combine theory and practice to describe the economic structural and behavioural characteristics of sectors integral to the construction industry performance. Construction Supply Chain Economics details 'everyday' experiences and procurement decisions made by people in firms in the industry related to projects as they seek out other firms to work with during the tendering stage. London creates a language that enables us to classify and understand behaviour and recognise the impact of our decisions on firms and projects within the industry. Construction Supply Chain Economics introduces a new model for mapping the construction sector of particular interest to construction management and economic researchers and to procurement decision makers, including policymakers and clients, as well as industry practitioners, such as contractors, consultants and materials suppliers

Judgement, reflexivitiy and interdisiciplinarity : reframing construction management education

A core skill of the construction management professional is decision making. Disciplinary content knowledge provides the basis for effective decision making, but is largely insufficient in contexts where projects demand a responsive and flexible approach to scenarios as they evolve and change. As Beckett and Hager suggest, &lsquo;professional practice requires a much richer set of phenomena &ndash; a capacity to make judgements, sensitivity to intuition and an awareness of the purposes of the actions are all involved &lsquo;(2002: 12). This paper begins by exploring judgement to develop a conceptual model for initiating and developing decision making skills for construction management professionals. The capacity to respond to change in a structured and self aware manner is examined through the concept of reflexivity, a concept borrowed from sociology. Reflexivity is an individual&rsquo;s capacity to be aware, responsive and adaptability to constant changing and evolving environments. Coupled with this is the challenge for all built environment professionals in the need to integrate knowledge and processes from various specialist knowledge domains, particularly design domains. The conceptual model is then refined by synthesising concepts from interdisciplinary research.The aim of this paper is to describe a framework to analyse and review current undergraduate and postgraduate coursework programs offerings from Deakin University in the School of Architecture and Building. Following Boud and Falchikov (2007) this framework starts with practice, that is, the actual &lsquo;doing&rsquo; of construction management as the basis for shaping curriculum development.<br /

Building information modelling project decision support framework

Building Information Modelling (BIM) is an information technology [IT] enabled approach to managing design data in the AEC/FM (Architecture, Engineering and Construction/ Facilities Management) industry. BIM enables improved interdisciplinary collaboration across distributed teams, intelligent documentation and information retrieval, greater consistency in building data, better conflict detection and enhanced facilities management. Despite the apparent benefits the adoption of BIM in practice has been slow. Workshops with industry focus groups were conducted to identify the industry needs, concerns and expectations from participants who had implemented BIM or were BIM “ready”. Factors inhibiting BIM adoption include lack of training, low business incentives, perception of lack of rewards, technological concerns, industry fragmentation related to uneven ICT adoption practices, contractual matters and resistance to changing current work practice. Successful BIM usage depends on collective adoption of BIM across the different disciplines and support by the client. The relationship of current work practices to future BIM scenarios was identified as an important strategy as the participants believed that BIM cannot be efficiently used with traditional practices and methods. The key to successful implementation is to explore the extent to which current work practices must change. Currently there is a perception that all work practices and processes must adopt and change for effective usage of BIM. It is acknowledged that new roles and responsibilities are emerging and that different parties will lead BIM on different projects. A contingency based approach to the problem of implementation was taken which relies upon integration of BIM project champion, procurement strategy, team capability analysis, commercial software availability/applicability and phase decision making and event analysis. Organizations need to understand: (a) their own work processes and requirements; (b) the range of BIM applications available in the market and their capabilities (c) the potential benefits of different BIM applications and their roles in different phases of the project lifecycle, and (d) collective supply chain adoption capabilities. A framework is proposed to support organizations selection of BIM usage strategies that meet their project requirements. Case studies are being conducted to develop the framework. The results of the preliminary design management case study is presented for contractor led BIM specific to the design and construct procurement strategy

Adopting building information modeling (BIM) as collaboration platform in the design industry

This paper discusses the preliminary findings of an ongoing research project aimed at developing a technological, operational and strategic analysis of adopting BIM in AEC/FM (Architecture-Engineering-Construction/Facility Management) industry as a collaboration tool. Outcomes of the project will provide specifications and guidelines as well as establish industry standards for implementing BIM in practice. This research primarily focuses on BIM model servers as a collaboration platform, and hence the guidelines are aimed at enhancing collaboration capabilities. This paper reports on the findings from: (1) a critical review of latest BIM literature and commercial applications, and (2) workshops with focus groups on changing work-practice, role of technology, current perception and expectations of BIM. Layout for case studies being undertaken is presented. These findings provide a base to develop comprehensive software specifications and national guidelines for BIM with particular emphasis on BIM model servers as collaboration platforms

Modelling housing supply and monetary policy within the context of global economic turbulence

Housing supply is an essential component of the property sector. Compared with an increasingly strong housing demand, the growth rates of total housing stock in Australia have exhibited a downward trend since the end of the 1990s. Over the same period, the significant adjustments in the Australian monetary policy were being implemented under a turbulent global economic climate. This research aims to identify the relationship between housing supply and monetary policy within the context of global economic turbulence by a vector error correction model with a dummy variable. The empirical evidence indicates that the monetary policy changes and global economic turmoil can significantly affect the supply side of the housing sector in Australia. The models developed in this study assist policy makers in estimating the political impacts in the global context

New housing supply and residential construction costs in Australia : a panel ECM approach

The supply of new housing in Australia has been experiencing a low increase rate since the 1990s in conjunction with an increasingly strong housing demand. On the contrary, residential construction costs across Australia?s states maintained dramatic increases simultaneously. Economic theory suggests that new housing supply is correlated to the costs of residential constructions. However, few empirical studies have focused on examining this relationship for Australian housing markets. To comprehensively investigate the relationship between the supply of new housing and residential construction costs a function for new housing supply considering the effects of regional heterogeneities is introduced in this study. By estimating a panel error correction model (ECM) applicable for quantifying the correlation with regional heterogeneities, this research identifies that a causal link and a strong correlation exist in between new housing supply and residential construction costs in Australia

Client managment on house projects : faciliating client learning for successful architect-client relationships

This paper reports the findings of a study which examined architect-client relationships on house projects with a focus on the supportive role of architects in helping clients deal with project issues. Habitus theory explains that the nature of architecture as a specialised activity places architects within an architectural habitus, distinguishing them from clients who are not trained in the field, which is at the heart of the problematic architect-client relationship. An underlying premise was that habitus shock, that is, a mismatch between the architect and client\u27s habituses Occurs as they enter into a relationship on the house project. Using the qualitative approach underpinned by the constructivist perspective for data collection and analysis, eight in-depth interviews were conducted across five case studies of successful architect-client relationships. The narrative inquiry approach was used to establish the extent to which habitus shock occurred and to describe the stages involved in the client\u27s adjustment process during habitus shock. The findings indicate that habitus shock occurred on all five case studies, which resulted in client learning, enabling clients to function with competency in the unfamiliar environment. Client learning achieved during habitus shock was directly linked to the amount of difficulty experienced. This study has refined our understanding of the architect-client relationship on house projects by exploring more deeply client behaviour and the ways in which clients successfully deal with difficulties on house projects rather than simply identifying the uncertainties and conflicts that occur on projects. The findings demonstrate that client learning during habitus shock is a characteristic of successful relationships. One of the most significant outcomes of thi s study is that it demonstrated the potential to facilitate client learning during habitus shock to contribute to the development of successful architect-client relationships.<br /

Habitus shock : a model for architect-client relationships on house projects based on sociological and psychological perspectives

The widening gap between architects and clients and the associated problems in the management of their relationship have long been recognised by practitioners and researchers alike. An emerging trend in recent studies is to develop descriptive models to describe behavioural characteristics of relationships based on observations of \u27 real world\u27 practice, indicating the significance of understanding the complexities of the social environment in which the architect-client relationship is within. This research built upon the work of past descriptive models by exploring the architect-client relationship on house projects with a focus on the client\u27s voice. It is an interdisciplinary study drawing theory from sociology to further understand this built environment industry problem. Sixty-nine percent of architects in Australia spend some of their work time on house projects and therefore improvements in this area can have significant impact on a considerably large portion of the profession. Habitus theory borrowed from sociology explains that the nature of architecture as a specialised activity places architects within an architectural habitus, distinguishing them from clients who are .not trained in the field. An underlying premise of thi s study is that a mismatch between the architect and client\u27s habituses occurs as they enter into a relationship on the house project. This phenomenon is termed habitus shock, referring to the client \u27s experience of disorientation as they are confronted with an unfamiliar architectural habitus on the project. Culture shock theory is examined for its contribution to explain the process to which the client adjusts to the unfamiliar environment during habitus shock. The habitus shock model proposed in this paper suggests that the client may achieve learning during habitus shock and it is this client learning that can lead to successful relationships.<br /

A reflexive capability model for sustainable e-business environments in construction supply chains

Despite the increasing significance of e-business worldwide and construction market leaders developing innovative e-business applications, the widespread uptake in the Australian construction industry is lagging. There has been considerable literature related to e-business adoption focusing on drivers and barriers to adoption. However, there has not been an investigation that has applied fundamental supply chain theory concepts. In this paper a reflexive capability model for the individual firm in relation to e-business is developed which relies upon merging economic and social practices through an industrial organization economic theoretical lens and social science theories of communication. The reflexivecapability model proposed within this paper describes a framework for theorization of the different degrees of e-business adoption exhibited by individual firm&rsquo;s and accounts for social-cultural, organisational-structural, communicative and economic (market and supplychain) barriers, influences and pressures to adopt e-business.The model is proposed for the construction supply chain to enable awareness, engagement and realization of e-business technology and achieve long term construction e-business sustainability.<br /
