The Limitations of current Working practices on the development of Computer Integrated Modelling in Construction

Abstract: For the Construction Industry to improve its processes through the application computer-based systems, traditional working practices must first change to support the integrated control of design and construction. Current manual methods of practice accept the limitations of man to process a wide range of building performance and production information simultaneously. However when these limitations are removed, through the applications of computer systems, the constraints of manual methods need no longer apply. The first generation of computer applications to the Construction Industry merely model ed the divided and sequential processes of manual methods i.e drafting, specification writing, engineering and quantity calculations, estimating, billing, material ordering data-bases and activity planning. Use of these systems raises expectations that connections within the computer between the processes model led can actually be made and faster and more integrated information processing be achieved. "Linking" software is then developed. The end result of this approach was that users were able to produce. information faster, present it in an impressive manner but, in reality, no perceived improvement in actual building performance, production economy or efficiency was realised. A current government sponsored Teaching Company Programme with a UK design and build company is addressing the problem of how real economic benefit can be realised through improvement in, amongst other things, their existing computer applications. This work is being carried out by both considering an academic conceptual model of how "designing for production" can be achieved in computer applications and what is immediately realisable in practice by modeling the integration of a limited number of knowledge domains to which computers are already being app1ied.i.e. billing from design, estimating and buying. This paper describes each area of work and how they are impacting on each other.
