Frequent assessment of as-built conditions is necessary for active
project control during construction. Assessment of as-built conditions
involves collecting accurate as-built information and comparing the
as-built information collected with given design and schedule information.
Currently, different technologies exist for collecting accurate and
comprehensive as-built information. The as-built information generated
through these technologies is then manually evaluated by comparing
it to the design information. This process is time-consuming and
error prone. Therefore, there is a need for an automated assessment
of as-built conditions. This paper discusses the applicability of
the Industry Foundation Classes (IFC) in their current version 2x
to support the assessment of as-built conditions of construction
projects. The goal is to create a project model that represents and
integrates as-built and design information. In this paper, we state
different types of information that need to be represented in this
integrated model, describe common ways of representing this information
in IFC Rel.2x, and highlight the limitations of current IFC Rel.2x
specifications in representing an integrated design and as-built
model. The paper concludes with a proposal for extending the IFC
specifications to enable the automated assessment of as-built conditions.
