The topic of data and information quality (DQ/IQ) is a longstanding issue of interest in both academia and practice in the construction engineering field. Poor DQ/IQ has led to poor engineering drawings that, in turn, have led to delays and eventuality to cost overruns. In this paper, we report a study that took an Action Design Research (ADR) approach to develop and evaluate a DQ/IQ assessment tool, which we call Information Quality System (IQS), in a large global engineering and construction company. The evaluation was performed by comparing the level of DQ/IQ in a project that used IQS with two projects that did not use the tool. The result is encouraging: the DQ/IQ in the project using IQS was significantly higher overall than in the two other projects. The implication is that a tool based on the design principles on which IQS was built is likely to help improve DQ/IQ in engineering systems and, hence, in engineering drawings. Consequently, it will decrease project delays and cost overruns. More generally, our paper adds to the discourse in the literature on the use of information and communication technologies (ICT) in the construction context. Our paper illustrates another successful application of action-oriented research that can solve practical problems while generating academic knowledge. In taking a design approach, we augment the literature on the use of action research in construction engineering and management.
