BIM is capable of generating cost estimate directly from a 3D model. It can thus offer a significant benefit by creating accurate and fast cost plans during different design stages, thereby increasing the quantity surveyor’s ability in cost planning and control. However, quantity surveyors are generally reluctant to adopt BIM due to their resistance to change to the model-based quantity take-off and estimate, data interoperability between BIM and estimating tools, undefined model outputs at various project stages, and incompatible BIM information classification systems with the traditional elemental cost planning formats. In order to overcome these problems, a BIM-based pre-contract cost planning and control framework is proposed. Based on the UniFormat information classification system for model elements, the proposed framework consists of four levels of estimate based on LOD100, 200, 300 and 350/400 model elements, respectively. It has also incorporated the measurement principles which are formulated based on the specified amount of graphical and non-graphical information for each model element. Quantity surveyors can systemically measure individual generic and precise elements or items according to defined information contents and measurement principles, thus leading to a more accurate estimate. This helps improve the industry practice in cost planning and control and systemically refines the existing standard method of measurement in alignment with the latest BIM development.
