Dr. Calahorra-Jimenez aims to improve the management of public infrastructure projects by researching on:
- Alternative project delivery systems such as Design-Build, Progressive-Design Build, and Alliances/Integrated project delivery.
- Procurement methods such as Best-Value
- Performance-Based Contracts
- Digital project development & Delivery, including BIM and virtual/augmented reality.
