Over the years, construction projects in Nigeria have been delivered using conventional methods. These methods have long been challenged by cost overruns, delays, poor project outcomes, and stakeholder conflict, particularly in public building projects. Integrated Project Delivery (IPD) has emerged globally as an innovative delivery approach to improve current methods and increase project performance by integrating collaboration, shared risk and reward, and the people, systems, and practices throughout the project lifecycle. This study aims to assess the key critical success factors for implementing IPD in public building projects in Anambra State, Nigeria. To achieve this, the hypothesis was formulated that no significant correlation exists between stakeholder collaboration and the success of IPD implementation in public building projects. The study adopted a descriptive research design. Ninety-two (92) copies of the questionnaire were administered to professionals in the Ministry of Housing in Anambra State. From the analysed data, the key critical success factors for IPD implementation were early stakeholder involvement (4.75), collaboration mindset (4.66), sharing risk and reward (4.59), mutual respect and trust (4.56), and multi-party contract (4.41). The study recommended that the government should strengthen its procurement policy to allow the implementation of collaborative delivery approaches such as IPD. Regular workshops, seminars, and training programmes on BIM, Lean practices, and IPD should be provided for public building construction stakeholders. Finally, the study contributed to the knowledge on IPD by highlighting the importance of stakeholder collaboration and other key success factors in the successful implementation of Integrated Project Delivery in public building projects in Anambra State.
