Description grammars
A general notation
A description grammar, in conjunction with a shape grammar, serves to generate verbal descriptions of designs, next to the spatial descriptions. These verbal descriptions can also assist in guiding the generative process. This paper presents a general notation for descriptions and description rules that accounts, extensively if not entirely, for many of the applications of description grammars found in literature. Specifically, a review of the notation with respect to these description schemes supports the explication of its strengths and limitations and the identification of future work. A follow-up paper revisits selected applications of description grammars and demonstrates the applicability of this general notation to these case studies.

Description grammars
Precedents revisited
A description grammar, in conjunction with a shape grammar, serves to generate verbal descriptions of designs, next to the spatial descriptions. These verbal descriptions can also assist in guiding the generative process. This paper revisits applications of description grammars found in literature and demonstrates how they can be recast and redeveloped to make use of a general notation and implementation for description grammars. The review of this notation was the topic of a previous paper; this paper is both meant as an illustration and as a confirmation of those review analysis results.

Shape grammars come in a variety of forms. Algebras of shapes have been defined for spatial elements of different kinds, as well as for shapes augmented with varying attributes, allowing for grammar forms to be expressed in terms of a direct product of basic algebras. This algebraic approach is extended here to the algebraic derivation of combinations of basic shape algebras with attribute algebras. This algebraic abstraction at the same time serves as a procedural abstraction, giving insights into the modular implementation of a general shape grammar interpreter for different grammar forms.

Thee computation of description grammars
Two case studies
We revisit two case studies that adopt a shape grammar to
relate different architectural styles. Both adopt a description scheme,
augmenting the shape grammar, as the main vehicle for relating different
styles, however, they both present the description rules only
conceptually. Following a description grammar interpreter and its notation
for descriptions and description rules, we explore a valid explication
of both description schemes. This exploration serves three purposes:
firstly, as a demonstration of the notation adopted; secondly, as
an evaluation of the applicability of the description grammar interpreter
and its notation to these case studies; and, thirdly, as a demonstration
of the explication of description grammars from concept to
computation.

Globalization and international competition force the AEC industry to change its work and collaboration practices. The traditional way of working is evolving into a more integrated process, and the traditional use of “synchronized passive” files and paper-based communication is being replaced with ICT based solutions. Currently, the AEC community is at an intermediate stage, i.e., it is shifting to “online” electronic documents. In this paper, a new concept called “eDocument” (eDoc) is introduced. The eDoc project is a cooperative effort of three research teams, in order to develop and implement a generic dynamically structured, multi-media, multi-channel, and multi-modal information system as a means for communication in AEC projects. The major innovation in the concept is that, although it uses a repository, the focus is on the “logical and physical” specifications of the eDoc concept as a shared tele-workspace that is accessible through multiple platforms.

Considering the complexity of building processes, and the potential of Information, Communication, and Knowledge Technologies (ICKT) to support these processes, we propose the development of a Web-based Intelligent Modeling for Cooperative Engineering (IMCE) environment for the building sector. Build around an intelligent project model that supports the selection and organization of information according to the needs of the user, various technologies, research efforts, and applications contribute to the design and development of this IMCE environment. In this paper, we present the context with respect to ICKT use in the building sector, define the objectives and approach of the IMCE project, and consider various aspects and research components contributing to this project.
