A research effort for enabling the integrated use of information within a construction enterprise needs to deal with diverse issues such as information centrality, information and service level integration strategies, and building up successful enterprise architecture within the Organisation. Enterprise Resource Planning (ERP) systems have emerged to achieve the capability to plan and integrate enterprise-wide information resources. However, ERP implementations in the construction industry have so far yielded more failures than successes due to inconsistencies between the process definitions of standard ERP applications and the processes construction industry. Thus, the integrative function of ERP systems can not be fully realised by the construction industry. This paper presents the findings of a study that aimed to determine the role of ERP systems used in the construction industry in enabling integration, specifically at data and information levels. In parallel with its aim, a framework for formalising the integration in data and information levels and a metric for measuring the integrative function of ERP systems in enabling data and information level integration are defined as a part of this research. The applicability of the proposed framework and metric is validated with four case studies in the final stage of the research.
