Previous work on automatic compliance checking has
targeted static descriptions of the built environment
represented in Building Information Models. In contrast,
this work examines the potential of semantic mark-up to
capture and then apply health and safety regulations to
live construction sites. There are significant differences in
what constitutes a testable metric and what constitutes a
fact when considering process rather than product
compliance. Extensions to the RASE approach are
defined and demonstrated to accommodate these
differences. This leads to extending the concept of
‘decidability’ with considerations around the relative
‘timeliness’ of information.
