However, at this stage planning documentation has not usually been drawn up to which this information can relate to. The common practice of commissioning an initial detailed survey is often too expensive as well as being time consuming. Moreover, the results do not always reflect the requirements of the planner or the researcher. Their information requirements are localised and are often successively intensified. An object-oriented approach for building surveying is proposed based upon a sketch-like iconic initial survey which can be progressively enriched with information detail. The objects and their inter-relationship is the central model rather that the geometry of the building. Different kinds of information can be related to building objects and made available to all the project participants. The implementation of the system was realised as a series of prototypes which communicate with one another using a common data model and working platform called freak. This system provides a model for a better organisation of information for all areas concerned with building conservation and World Heritage.

The "Colored Architecture" software prototype described in the paper is a modular part of current research activities at the Bauhaus-University Weimar. In addition to special tools and forms of visualization, the paper describes a concept for the fast, realistic, parameterized assessment of the factors color, material and light in architectural modeling. The traditional rendering of architectural models using radiosity light visualization is often too time-consuming to be used in the design process. To improve the workflow, the radiosity visualization described provides a physically correct visualization of the material whilst allowing the parameters color, material and light to be adjusted interactively. The "Colored Architecture" prototype is an integrated component of the Building Information Model and supports the professional planning of color, material and lighting concepts in architectural design.

This paper describes the theory and approach behind the software realisation of a tool which helps in finding the affine self-weight geometry of gridshell structures.

Using the information collected in a building survey the user should be able to "explore" the building in virtual form, as well as to assess the information contained with regard to a specific planning aspect.

This paper will discuss the IT concept of a building surveying system, the software and hardware prototypes developed as well as usability aspects of wearable computers.

One prototype uses MAXON’s CINEMA4D XPRESSO ® visual scripting environment to set up a semi-automated design environment which allows users to edit one featurebased 3D model of massing alternative at a time.The other prototype uses ILOG’s OPL STUDIO ® constraint programming environment to achieve fully automated search and 2D visualization of all possible solution alt...

This ongoing research examines optimization problems of site coverage and building massing, according to a the constraint satisfaction problems (CSP) paradigm. The case study is management housing programs, testing the Chilean standard regulations effective today. The BDS constitutes a novel approach on ICT support for the jointly income households and NGOs into production in developing countries.

This exploration is part of an ongoing major research towards an integrated planning support system for low-income housing; we called Esther, which is focused on the development of a network-based set of tools to support logistics of self-designed /-built dwellings life-cycle. Esther addresses the systemized collaborative work between dwellers and specialists during the whole development cycle of dwellings.

This dwelling belongs to state plans carried out in Chile to built houses for low-income people incorporating the users' participation. It reviews the enlargements and constructive improvements, areas, dimensions and distribution of rooms, and the motivations and decisions involved. It find out important regularities in the stages, traces and priorities of construction, mainly targeted to differentiate the occupation through periodic spatial additions.

Setting our sights on the implementation of modern IT (Information Technology) into architectural field to support the entire planning process, it will be exposed the general deficiencies, diverse IT-tools, their combination possibilities and their practical contribution in order to prove the feasibility of a computer-aided system within a new concept of housing planning.
