Flood events around the world result in the loss of human lives, disruption, damage to economic, infrastructural and ecological systems. Although, different frameworks to manage flood events exist; however, the complexity (i.e. adjustment and adaptation) associated with some of these approaches is often limited by constraints of time and resources. Therefore, this study attempts to apply a flexible project structure to schedule a post-flood recovery project (PFRP). Twenty-five (25) restorative activities in a PFRP were identified, categorised and scheduled as resource-constrained project scheduling problem with a flexible structure (RCPSP-FS). Monte Carlo simulation was used to reflect the uncertain characteristics of each restorative activity. PFRP completion time was 42 and 86 days under time and resource constraints assumptions, respectively. Thirty- four (34) network paths (sub-projects) were identified and grouped into 4 restorative measures as follows: (i) removal of hazardous materials (ii) evacuation
