Alternative Project Delivery and Procurement Methods in Transportation Projects

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.
