This case study investigates whether the adoption of practices related to integrated project delivery (IPD) process may bring about better performance of construction projects in Singapore. Data were collected using a structured questionnaire and analyzed using -tests and correlation. It was discovered that some IPD practices related to people affect project performance positively, indicating the importance of carefully selecting project participants. When team members form collaborative relationships, fully share project information and cooperate to achieve common project objectives, superior project performance is observed. This study found some IPD practices related to the contract that may affect project performance negatively. For example, contracts that share cost savings and cost overruns tend to have poorer schedule performance. Certain IPD practices are significantly associated with project performance; thus, recommendations are provided on how to boost project performance.
