Provisional handover is a critical stage in the life cycle of construction projects. At this stage, disagreements among clients, consultants, and contractors over delay responsibility, additional costs, and the fulfilment of contractual obligations may result in time- and cost-related claims. This study aims to identify and prioritize the factors contributing to claims associated with cost compensation and delay justification during the provisional handover of construction projects. In terms of purpose, the study is applied, and in terms of research design, it adopts a descriptive-survey approach. The statistical population consisted of engineers and construction professionals with at least five years of experience who had worked as clients, consultants, or contractors. The sample size was determined using Cochran’s formula at a 95% confidence level. Of the 150 questionnaires distributed, 113 valid responses were collected and analysed, resulting in a response rate of 75/3%. Okpala method was employed to assess the level of agreement among the three stakeholder groups regarding the importance of the identified factors. The findings indicate that the factors contributing to claims during provisional handover can be classified into two principal categories: time-related claims and cost-related claims. Differences were also observed among the perceptions of clients, consultants, and contractors concerning the importance of certain factors. The results may provide project managers and contracting parties with a basis for the proactive identification of claim-generating conditions, improved event documentation, reduced contractual disputes, and more efficient provisional handover procedures.
