store of information is not sufficient for knowledge management; the relationships
within the stored information are vital. These relationships cover such diverse
issues as relative importance, context, sequence, significance, causality and asso-
ciation (Christiansson, 2000). The potential for knowledge management tools is
vast; not only can they make better use of the raw information already available, but
they can sift, abstract and help to share new information, and present it to users in
new and compelling ways.
2.3 Integrated service delivery architecture
An integrated service delivery architecture was developed to enable a pervasive,
user-centered mobile work environment by bringing together technology compo-
nents as a framework for an intelligent remote collaboration infrastructure. The
architecture strongly links technological enabling elements such as mobile com-
puting, the Semantic Web, Web services, location-based services, user profiling,
multimedia and agent technologies with methodological, cultural, social and
organizational aspects specific to the construction industry. Figure 2.2 presents
the multitier integrated service delivery architecture.
