Knowledge and technology transfer from universities to industries: A case study approach from the built environment field
Enabling kowledge societies and knowledge based economies is a key policy in the UK. KTP (Knowledge Transfer Partnership) scheme initiated by the Technology Strategy Board is a pathway for collaboration and partnerships between Higher Education institutions and companies to transfer innovative knowledge based solutions from universities to businesses in order to equip them with the leading edge knowledge and technology infrastructure for sustainable long term competitive advantages in both national and international market.
The paper explains a KTP project between the University of Salford and John McCall Architects (JMA) in Liverpool in the UK that aimed to identify, map and re-engineer JMA’s strategic and operational change processes through Lean thinking and the implementation of Building Information Modelling (BIM), which is a foundational tool for implementing an efficient process and invariably leads to lean-orientated, team based approach to design and construction by enabling the intelligent interrogation of designs; provide a quicker and cheaper design production; better co-ordination of documentation; more effective change control; less repetition of processes; a better quality constructed product; and improved communication both for JMA and across the supply chain whereas it provided opportunity to increase business relevance of knowledge based research and teaching for the Higher Education.
Case Study approach is employed in the paper and the KTP project is assessed for i) how it helped in improving JMA’s knowledge and technology capacity in conducting their practice, and, ii) how it helped the university in improving its knowledge based research and teaching
Technology adoption in the BIM implementation for lean architectural practice
Justification for Research: the construction companies are facing barriers and challenges in BIM adoption as there is no clear guidance or best practice studies from which they can learn and build up their capacity for BIM use in order to increase productivity, efficiency, quality, and to attain competitive advantages in the global market and to achieve the targets in environmental sustainability.
Purpose: this paper aims to explain a comprehensive and systemic evaluation and assessment of the relevant BIM technologies as part of the BIM adoption and implementation to demonstrate how efficiency gains have been achieved towards a lean architectural practice.
Design/Methodology/Approach: The research is undertaken through a KTP (Knowledge transfer Partnership) project between the University of Salford and the John McCall Architects based in Liverpool, which is an SME (Small Medium Enterprise). The overall aim of KTP is to develop Lean Design Practice through the BIM adoption and implementation. The overall BIM implementation approach uses a socio-technical view in which it does not only consider the implementation of technology but also considers the socio-cultural environment that provides the context for its implementation. The technology adoption methodology within the BIM implementation approach is the action research oriented qualitative and quantitative research for discovery, comparison, and experimentation as the KTP project with JMA provides an environment for “learning by doing”
Findings: research has proved that BIM technology adoption should be undertaken with a bottom-up approach rather than top-down approach for successful change management and dealing with the resistance to change. As a result of the BIM technology adoption, efficiency gains are achieved through the piloting projects and the design process is improved through the elimination of wastes and value generation.
Originality/Value: successful BIM adoption needs an implementation strategy. However, at operational level, it is imperative that professional guidelines are required as part of the implementation strategy. This paper introduces a systematic approach for BIM technology adoption based on a case study implementation and it demonstrates a guideline at operational level for other SME companies of architectural practices
The interaction of lean and building information modeling in construction
Lean construction and Building Information Modeling are quite different initiatives, but both are having profound impacts on the construction industry. A rigorous analysis of the myriad specific interactions between them indicates that a synergy exists which, if properly understood in theoretical terms, can be exploited to improve construction processes beyond the degree to which it might be improved by application of either of these paradigms independently. Using a matrix that juxtaposes BIM functionalities with prescriptive lean construction principles, fifty-six interactions have been identified, all but four of which represent constructive interaction. Although evidence for the majority of these has been found, the matrix is not considered complete, but rather a framework for research to
explore the degree of validity of the interactions. Construction executives, managers, designers and developers of IT systems for construction can also benefit from the framework as an aid to recognizing the potential synergies when planning their lean and BIM adoption strategies
Models and metaphors: complexity theory and through-life management in the built environment
Complexity thinking may have both modelling and metaphorical applications in the through-life management of the built environment. These two distinct approaches are examined and compared. In the first instance, some of the sources of complexity in the design, construction and maintenance of the built environment are identified. The metaphorical use of complexity in management thinking and its application in the built environment are briefly examined. This is followed by an exploration of modelling techniques relevant to built environment concerns. Non-linear and complex mathematical techniques such as fuzzy logic, cellular automata and attractors, may be applicable to their analysis. Existing software tools are identified and examples of successful built environment applications of complexity modelling are given. Some issues that arise include the definition of phenomena in a mathematically usable way, the functionality of available software and the possibility of going beyond representational modelling. Further questions arising from the application of complexity thinking are discussed, including the possibilities for confusion that arise from the use of metaphor. The metaphor of a 'commentary machine' is suggested as a possible way forward and it is suggested that an appropriate linguistic analysis can in certain situations reduce perceived complexity

The role of the supply chain in the elimination and reduction of construction rework and defects: an action research approach
Since 2007, Ireland has suffered a circa 80% reduction in construction output. This has
resulted in bankruptcy, unemployment and bad debt. Contractors have attached greater
emphasis to production efficiency and cost reduction as a means of survival. An Action
Research (AR) strategy was used in this research to improve processes adopted by a SME
contractor for the control of defects in its supply chain. It is conservatively estimated that
rework, typically accounts for, circa 5% of total project costs. Rework is wasteful and
presents an obvious target for improvement. The research reported here concerns the (first)
diagnosing stage of the AR cycle only, involving: observation of fieldwork, analysis of
contract documents, and semi-structured interviews with supply chain members. The results
indicate potential for supply chain participants to identify root causes of defects and propose
solutions, having regard to best practice to avoid re-occurrence. A lack of collaborative
forums to contribute to production improvement was identified. Additionally the processes,
used to collect, manage and disseminate data were unstructured and uncoordinated, indicating
scope for developing more efficient methods. The research indicates good understanding of
the potential benefits for supply chain collaboration but suggests that the tools and knowledge
to collaborate are currently lacking in the SME sector
Design management: changing roles of the professions
This paper sets out to explore how recent changes in
procurement in construction have affected the roles that
professions play in the design process. It discusses how
professions that traditionally took the role of design
manager now find themselves participating within
previously unforeseen contexts, working in multidisciplinary
teams led by contractors and with changed
responsibilities at the design stage. Supply chain members
who were not previously involved during the early project
phases are being engaged at the earliest phases of the
project life cycle and even taking leadership roles while
designers sometimes work as supply chain partners.
A study of design in construction and other sectors shows
that in dealing with design management issues it is critical
to deepen appreciation for the unique characteristics of
design and the design process. The paper argues that
contractors and designers taking on design management
roles in a dynamic industry seeking to explore best
practice and innovative approaches to procurement and in
the delivery of projects need to acquire new skills,
management education and develop the necessary
qualities
Smart homes and their users:a systematic analysis and key challenges
Published research on smart homes and their users is growing exponentially, yet a clear understanding of who these users are and how they might use smart home technologies is missing from a field being overwhelmingly pushed by technology developers. Through a systematic analysis of peer-reviewed literature on smart homes and their users, this paper takes stock of the dominant research themes and the linkages and disconnects between them. Key findings within each of nine themes are analysed, grouped into three: (1) views of the smart home-functional, instrumental, socio-technical; (2) users and the use of the smart home-prospective users, interactions and decisions, using technologies in the home; and (3) challenges for realising the smart home-hardware and software, design, domestication. These themes are integrated into an organising framework for future research that identifies the presence or absence of cross-cutting relationships between different understandings of smart homes and their users. The usefulness of the organising framework is illustrated in relation to two major concerns-privacy and control-that have been narrowly interpreted to date, precluding deeper insights and potential solutions. Future research on smart homes and their users can benefit by exploring and developing cross-cutting relationships between the research themes identified
The identification and analysis of making-do waste: insights from two Brazilian construction sites
Making-do has been pointed out as an important category of waste in the construction industry. It refers to a situation in which a task starts or continues without having available all the inputs required for its completion, such as materials, machinery, tools, personnel, external conditions, and information. By contrast, the literature points out that improvisation is a ubiquitous human practice even in highly structured business organizations, and plays an important role when rules and methods fail. The aim of this paper is to provide some insights on the nature of making-do as a type of waste, based on two exploratory case studies carried out on construction sites. The main contributions of this research work are concerned with the identification of different categories of making-do and its main causes. This paper also discusses some strategies for reducing making-do on construction sites
