BIM governance assessment instrument is a process of analysing the condition of the importance in developing BIM governance solution to tackle most of the existing problems during team collaboration in BIM-based projects. Despite the development and deployment of integrative and collaborative technologies in construction industry particularly BIM, the industry is still insufficient compare to other sectors. Several studies have been established the requirements of BIM implementation concerning all technical and non-technical BIM adoption issues. However, the data are regarded as inadequate to develop a BIM governance framework. Hence, the objective of the paper is to evaluate the content validity of the BIM governance instrument prior to the main data collection. Two methods were employed in the form of literature review and questionnaire survey (8 content experts). Based on the literature review, 273 items with six (6) main constructs are suggested to be incorporated in the BIM governance instrument. The CVR scores revealed that 202 out of 273 items are considered as the utmost critical by the content experts. The findings for I-CVI and modified kappa coefficient however revealed that 257 items in BIM governance instrument are appropriate and excellent. The instrument is highly reliable and the items selected are appropriate.
