The interdisciplinary conceptual design of buildings

The Interdisciplinary Conceptual Design of Buildings Design activity during the conceptual phase of building projects is dynamic, vibrant and as a result, chaotic in appearance. This problem is compounded by the fact that iterative, or cyclic, design progression is often criticised, with the concept of 'going round in circles' being one that is discouraged. However, designbis a learning activity and, owing to the complexity of contemporary building projects,it is often only by moving ahead to improve knowledge, before taking a step back to re-address a problem with improved understanding, that the design process can progress. Today's design professionals are being urged to undertake early design activity in a more programmable, and thus manageable fashion. As such, it is becoming increasingly apparent that designers have little, if any, shared understanding of what conceptual design actually involves, let alone a deeper knowledge of the structure of iterative progression. This can, and is, causing problems for the industry, as the lack of both common understanding and synchronisation in interdisciplinary thinking is resulting in design team fragmentation and adversarial relationships. By modelling design activity it is possible to simplify, and thus ease understanding of, its complexities. The development and trialling of a generic framework of design phases and activities has allowed a simple graphical means of recording and displaying patterns of design progression to be devised. The models produced have been used to study and analyse the patterns of iterative working, the output of which has enabled a clarification of conceptual design practice to be achieved. A web-based design system has been developed from the paper-based framework. This accords well with the richly iterative and often non-linear process which design typically follows and is intended to encourage creativity without imposing a rigid procedure. The tool offers alternative routes through conceptual design, and contains 'Team Thinking Tools' to help designers widen the solution space, set priorities and evaluate options. In addition, it promotes effective teamwork practices to help teams deal with social interactions. Also, at the user's option, the system can be used to capture, store and retrieve decisions made, and the reasoning behind them. This is of key importance in improving the performance of the industry as a whole, for it is only by understanding how the final product is influenced by early design activity, that the design process can be adapted to take account of these issues on future projects

Improving building design through integrated planning and control

The construction industry is acutely aware of the need to improve the integration, planning and control of its design and production processes. A number of projects undertaken within Loughborough, Salford and Cambridge Universities, in collaboration with a number of construction industry organisations, are addressing this issue by investigating, and developing tools to assist, the design and construction process. Emerging from these projects is the common need for IT systems and support that will facilitate the capture, storage and retrieval of project knowledge. It is only by relating these compatible IT applications to a common and recognisable project process framework that construction industry organisations will be able to make optimum use of the available technological developments. This paper describes the development of techniques and strategies to support the integrated planning and control of design through the collaboration of the main designers, suppliers and contractor working on complex building projects, and discusses the relevance of clustering these in relation to the phases and activities of a generic model of design and construction

Modelling and managing project complexity

The Architecture, Engineering and Construction (AEC) industry, like many others, is increasingly aware of the need to improve efficiency and effectiveness to thrive in an increasingly competitive marketplace. A key discovery in their search for improvements is the benefits of repeatability in both processes and products. However, although the latter has seen significant advances, such as the adoption of pre-assembly and standardised components and systems, the industry has experienced far greater difficulties identifying ways of capturing, understanding, and replicating work processes. The identification and removal of waste from the process can only be achieved once the process has been captured. Their repeated use and development, combined with analysis with the Analytical Design Planning Technique, enable the improvement of work practices and culture in terms of integration, decision-making and reductions in re-work

Benefits derived from use of DSM as part of the ADePT approach to managing engineering projects

Papers have been presented on the ADePT planning and management approach at DSM Conferences going back to 2000. The approach is now in widespread use in industrial applications, ranging from a US$4M building fit-out project to a £4Bn urban redevelopment project, and a number of practices have been established to ensure design planning and control is undertaken in the most effective way possible. The impacts of the approach’s use have recently been assessed, highlighting a number of areas where benefit is derived and showing a significant return on the investment required to implement the technique

An internet-based system to support interdisciplinary and inter-organisational collaborative conceptual design

This paper builds on work presented at the last two CIBSE conferences, and describes the development of an Internet-based design tool to support interdisciplinary teams during the conceptual phase of the design process. Originally, devised as a paper-based framework comprising five phases and twelve activities, the interactive internet-based version accords well with the richly iterative and often non-linear process which design typically follows. The tool is intended to encourage inspirational concept design without imposing a rigid procedure. As well as offering alternative routes through concept design, the tool contains ‘team thinking tools’ to help designers widen the solution space, set priorities and evaluate options. In addition, drawing on management science literature about effective teamwork practices, it helps a team deal with social interactions. Also, at the user’s option, the system can be used to capture, store and retrieve decisions made, and the reasoning behind them. Overall the system, which exists as a working prototype, offers the combined prospects of decision support, an audit trail, and improved knowledge management. The prototype is available openly on the web, and constructive feedback from users is welcomed. At least one of the collaborating organisations is adapting the system to its individual needs and embedding it within its own operating procedures

Using training workshops to map interdisciplinary team working

Contemporary building projects are increasingly complex and demand close integration between the design of the building services and the fabric. The early stages of the design process, when alternative concepts are being generated and the least promising are eliminated, are recognised as crucial, since they define the parameters within which the whole project will be constrained. AMEC Design, a large practice of building service engineers, surveyors, architects and other building design professionals is committed to interdisciplinary teamwork at the conceptual phase of design, and is participating with other construction organisations and with the University of Cambridge in research to map the process of design at the concept phase. Workshops for design team members are run regularly by the company as part of its staff development programme. A recent workshop provided an opportunity to monitor interdisciplinary design teams and to develop an initial 12-phase model of the conceptual design process. The process as observed was clearly non-linear, implying the need for models which allow flexible interpretations. Future revisions will be followed by further testing in similar workshops, and eventually its application on live projects

Mapping the early stages of the design process - a comparison between engineering and construction

The conceptual stage of a construction project is a vibrant, dynamic and creative period. Ideas are generated rapidly about the nature of the project, the requirements and desires, and potential solutions. But this period can also be disorganised and even chaotic; there are many uncertainties about the project, and the risks are high. Design team members may be unfamiliar to each other and unaccustomed to one anothers' ways of working. Maps of the design process are intended to obviate the need for the design team to re-invent the process each time, and to contribute to a working environment in which good design can flourish. Several process maps already exist for construction. One of the best known in the UK is the Plan of Work published over 30 years ago by the Royal Institute of British Architects, and whose terminology continues to be used throughout the industry. Recently other maps of the process have begun to emerge, some from industry, others from academic institutions. Neither the RIBA Plan of Work, nor more recent maps, give in-depth support to the concept phase. At the Department of Architecture at Cambridge University we are working with a number of construction industry firms (AMEC Design, BAA, Hotchkiss Ductwork Ltd, Hutter, Jennings & Titchmarsh, Matthew Hall, Pascall & Watson) on Mapping the design process during the conceptual phase of building projects. The project runs from April 1998 to March 2000 and is funded by the UK Engineering and Physical Sciences Research Council. Loughborough University is also involved in the project. It focuses on two areas: i) the collation, evaluation and potential transfer of established mapping methods and design techniques at the concept stage from engineering and other industries to construction; and ii) the refinement, testing and exploitation of these design techniques by construction industry designers
