The purpose of this paper is to examine green building legislation requirements and practices in the construction project execution stage within the context of the South African construction industry. The rationale for this examination rests with the perception that the implementation of green practices (per se) has been recognised as being “behind” the legislation enacted to control the design and construction of green buildings.

The research process consisted of a literature review to identify existing green building legislation and practices applicable to the project execution phase. This was supported by a sequential mixed-method research approach, which involved a survey of contracting companies based in the Western Cape Province of South Africa. Purposive sampling was used to undertake focused interviews with management staff and site operatives.

Research findings established a number of issues, not least: a gap between green building practices and legislation requirements; a high degree of unawareness of green building legislation/practices by construction company stakeholders; selective implementation of health and safety legislative requirements; that management staff had a more “positive” attitude to green building practices than site-based staff who tended to be less motivated and open to such practices.

Results from this study are considered generalisable with the sample frame only. Research inference and projections should therefore only be made within this set, and not to the wider population of South African contractors (as this study was limited to the Western Cape Province).

Implications from this research are applicable to construction company stakeholders within the population set. Practical considerations include the need to acknowledge a formal commitment to developing a sustainable built environment – especially cognisant of the gap between practices on site and green building legislation requirements. Moreover, this lack of awareness in respect of green building practices and legislation requirements impinges upon several wider areas, not least: construction company stakeholders’ positioning, health and safety practices; managerial and operational staff perceptions, and stakeholders’ willingness and motivation to proactively address these gaps.

Government bodies and allied professionals in charge of construction industry development are encouraged to consider the implementation of green building legislation requirements on construction sites. This reflection should encourage engagement through formative legislative provision and transparent awareness campaigns.

This work is original insofar as it directly addresses the alignment of legislation to current practices within the context of the South African construction industry. However, similar exercises have been undertaken on green building legislation in other countries such as USA, UK and Australia.

Humans tend to rely on beliefs, assumptions and cognitive rules‐of‐thumb for making judgments and are biased against taking more uncertain alternatives. Such inertia has implications for client organizations' decision making about innovations, which are inherently more uncertain than conventional alternatives. The purpose of this paper is to contribute to furthering the understanding of barriers to overcoming inertia in client decision making in new‐build.

A descriptive behavioural decision‐making perspective is combined with an organizational information‐processing perspective. To identify and discuss individual and organizational barriers that potentially distort clients' decision making on innovation, the analysis addresses aggregated data from four studies. The analysis focuses on inferences and interpretations made by decision makers in Swedish client organizations, their information‐processing practices and the subsequent impacts on perceived meanings and judgments about industrialized multi‐storey, timber‐framed building innovations, which are perceived by Swedish clients as new and different building alternatives.

Cognitive and organizational barriers maintain status‐quo decisions. Clients are inclined to make biased judgments about industrialized‐building alternatives because non‐applicable cognitive rules‐of‐thumb, based on their experiences of conventional‐building alternatives, are used. Furthermore, client organizations' information‐processing practices do not allow different meanings to surface, interact and potentially suggest different conclusions, at odds with established beliefs.

The paper's conclusions highlight how inertia is sustained in client decision making in new‐build. They illustrate the limitations of a common engineering approach, i.e. supporting decision making about innovations by focusing on providing more information to the decision maker in order to reduce uncertainty, as well as managing multiple meanings by reductionism.

The purpose of this paper is to find optimal solutions for conceptual design automation, which can be integrated with Building Information Modelling (BIM) support for construction automation. Problems relating ostensibly to failures in computational support for the conceptual design stage are well-documented in extant literature. These failures are multifarious and significant, with several deficiencies being acknowledged in the Architecture, Engineering, and Construction (AEC) industry. Whilst acknowledging this, extant literature has highlighted the importance of computational design in the AEC industry; and failures in this area include the need to strengthen the congruent links and support mechanisms in order to exploit the opportunities presented by new computational design methods. Given this, it is postulated that the application of generative design could enhance the design experience by assisting designers with the iterative generation of alternatives and parameterisation (change management) processes. Moreover, as BIM applications are increasingly providing comprehensive support for modelling and management, then additional synergies could be examined for further exploitation.

This paper focusses on the potential for developing an interactive BIM environment that purposefully adopts generative design as a method of computational design for the early design stages. This research facilitates the automation of the conceptual architectural design process, using BIM as the central conduit for enhancing the integration of the whole building design process (including design interfaces). This approach is designed to improve designers’ cognition and collaboration during the conceptual architectural design process.

This paper evaluates the existing methods and decision support mechanisms, and it introduces the potential of combining different concepts into a single environment (generative design/BIM).

This research is novel, in that it critically appraises virtual generative workspaces using BIM as the central conduit. The outcome and intervention of this research forms a theoretical basis for the development of a “proof of concept” prototype, which actively engages generative design into a single dynamic BIM environment to support the early conceptual design process.

Knowledge management literature predominant comes from a western perspective. The purpose of this paper is to report on an empirical study to find out if the organisations acting in less business environment such as Libyan organisations (banking in particular) will be able to implement a knowledge management system (KMS) and how they can benefit from it.

The study is built mainly around “what” question related to information processes within organisations within a social context. This study uses a case study approach using an interpretive perspective (a qualitative method) to map and describe relationships. This approach enables a greater degree of granularity to be captured.

The benefit of KMS is an essential step in defining critical areas in implementing a KMS and determining strategy in this research. The results show that KMS could be of most significance for enhancing the organisations' performance and led them to better position in today's competitive environment. These benefits are fundamental issues related to different encouragements in KMS implementation such as better decision‐making, improving the customer relationship and management, create new value through new services (innovations), and creating additional businesses.

The banking and financial sectors are fundamental drivers of innovation. In this context, their contribution to KM concept and applications are of specific value, especially concerning the leverage of intellectual capital. Knowledge intensive organisations like these are increasingly implementing KMS to drive forward their strategies and improve performance. This paper therefore, focuses specially on presenting a framework tailored to meet the banking and financial sector's needs.

Perceptions drawn from the construction management research (CMR) community regarding research impact (RI) and its relationship to theory generation (TG) are examined. Investigative emphasis is on RI and TG enablers and challenges (within an academic context). The paper aims to discuss these issues.

Qualitative narrative data accrued from open-ended questions within a structured questionnaire survey are analysed using frequency, quantitative content analysis, and graphical methods. A model of the RI/TG interface is presented and discussed.

Principal RI enablers are “facilitation” (industry engagement, time); while principal constraints include “internal factors” (the academic, the university) and “external factors” (collaboration, funding). Respective TG enablers are “resources” (competence, time, funding) and corresponding challenges include “external factors” (market forces, compliance). RI is considered a minor challenge to TG.

The study adds empirical evidence to the ongoing RI debate within the UK generally and with regard to the CMR discipline more specifically.

RI research is relatively sparse, while the findings in regard to CMR are entirely novel.

South Africa still has a considerable housing shortage. Government has tried to overcome this situation by creating programs to provide affordable housing to poor people. However, such housing is either often rejected by the beneficiaries or these express considerable dissatisfaction. This paper thus examines how value is constructed by key role players by looking at the building requirements that they promote, and asks whether there are any significant differences between the perceptions of housing providers and that of end-users, based on building requirements and location indicators. The rationale for the paper stems from the detection that low cost housing projects provided by government housing departments in South Africa (specifically, within the Western Cape Province) are either abandoned or considered non-satisfactory by beneficiaries and, therefore, seemingly not valued by them. This leads to the perception that low cost housing developments are unsustainable.

The methodology used in the paper is based on value management, and urban and social studies literature, and on a multi-case study comprising of three low-cost housing developments.

Results show that there are significant differences between the perception of key role players regarding what are important building requirements and location indicators and the corresponding end-user preferences based on location of the development.

Following the qualitative research approach used in the research, the main study limitations encountered include communication, because the low cost housing beneficiaries are predominately non-English speaking and have low level of literacy. This required the use of oral interviews, interpreters and translation of a significant number of the surveys into English. The data collected are therefore limited to the accuracy of the translations made by the translator.

Results suggest that end-user preferences must be taken into consideration by the government and the design team when planning low-cost housing developments in South Africa, and that this could be achieved by involving the end-users in decision-making during the low-cost housing development process.

This paper is of value to the national and provincial government in South Africa because it outlines the reasons for the lack of happiness and satisfaction among the poor and disadvantaged members of the community in the low cost government subsidised housing, and it suggests steps that can be taken by government to mitigate the housing problems. The paper is also of value to other key stakeholders such as the design consultants, contractors and government officials involved in the housing delivery process.

The purpose of this paper is to identify interdependent barriers to the search and selection of new technologies by design engineers at industry, organisation and individual levels. A “proof of concept” HyCon tool is presented to demonstrate the role of information technology design support tools in supporting designers to overcome these inhibitors, in this case for hybrid concrete, by providing immersive and interactive, information‐rich environments to explore design solutions.

The HyCon tool was developed through a prototyping methodology encompassing a testing, analysis, design and coding iterative cycle. This was supported by case studies and industry workshops.

The results of a collaborative research project are presented, which describes the HyCon design support tool to promote the understanding and use of hybrid concrete in structural frames. This tool is built around a knowledge creation, application, storage, and retrieval cycle to envision and support the use of this new technology.

This paper fulfils an identified need to integrate technology management and design process considerations within the context of an information technology design support tool, and offers a “proof of concept” HyCon tool to demonstrate key issues and potential utilities and applications.
