dc.description.abstractConventionally, construction cost estimates are prepared manually using paper-based, CAD-based or semi-automated approaches. These methods have been criticised for being labour intensive and error prone. However, with the advent of Building Information Modeling (BIM), researchers have proposed BIM-based costing frameworks based on which several cost estimating software applications have been developed. Despite the proliferation of these software tools, studies have reported slow pace of adoption of these tools by Quantity Surveyors globally. One of the major challenges hindering the widespread of usage and application of BIM-based estimating systems is the differences in cost estimating practices and measurement standards which differ from one country to another. Most of the current BIM tools are based on standards that do not adequately capture local cost estimating requirements, hence making the full adoption of these BIM tools difficult and unrealistic. The Industry Foundation Classes (IFC) as the major BIM data standard being utilised by various software vendors has been reported to be inadequate and insufficientbecause it doesnot capture most local requirements. This paper therefore aims at identifying the information requirements that support BIM-based cost estimating using the Nigerian local standard for estimating. This is with the view to establishing information needs for software developers to improve their cost estimating software applications. Using a qualitative research approach, a total of five (5) experienced consultant Quantity Surveyors were interviewed and data collected was analysed using content analysis. The study identified six (6) categories of information required to support BIM-based cost estimating using the Nigerian BESMM as a local cost estimating standard. The study concludes that unless these local are comprehensively captured by the IFC schema, the full benefits and potentials of BIM-based cost estimating tools will not be achieved.
