Conclusions

The bcoWeb contains open source reference definitions of BC terms (called objects) that are ordered with the intention to support decision making in a hierarchical decision process.

bcoWeb supports breaking down complex decisions (what type of power plant do we use) into simpler decisions (do we need a one or two story turbine building) and again in simpler decisions (do we use a concrete or steel frame) and even simpler decisions (what type of wall covering is desired). All the way down to the materials, connections and finishes. BcoWeb allows this on the Ontology level.

Object definitions are grouped in a natural way, i.e. the groupings map one to one to the languages of the various disciplines/stakeholders.

Looking at the current bcoWeb filling and the applications surrounding it, it is clear that the idea to build hierarchies of definitions of technical solutions (or function performers) provides BC with a new mechanism for electronic information and knowledge sharing in the various chains that has a number of advantages over earlier mainly paper-based mechanisms.

FU/TS hierarchies ensure that the definition of an object is not separate from its context and from its actual usage.

• Computer applications can use the bcoWeb to share a common view on the project.
• bcoWeb provides the flexible, commonly accessible BC language required for the development of `smart' computer applications that are able to behave as if they really understand the language(s) of Building-Construction.
• Smart computer applications (in the future including intelligent manipulators, equipment and construction robots) are able, like human co-workers, to complete tasks in close co-operation with other co-workers and other smart computer applications without human interference--though not without control (!!)--thus providing a promising new technology that seems able to drastically improve current BC processes.
• Providing Internet-based access to the data that underlie the textual document helps to integrate the documents in a greater whole. Catalogs can be used in object trees, an object tree's project data can be used in a Specification.
• Web services are a valid way to consume and to provide information.

The chapter shows that the open source, web-based, bcoWeb-structured, smart applications and web services-using approach can indeed be implemented and that it provides a new opportunity for the BC industry and society at large to increase the speed, controllability and quality of its processes and that it can help BC to become more dynamic, flexible, open, competitive, efficient and effective.
