Infrastructure projects involve many different public and private stakeholders and require excellent management and cohesion among the various players. In matters involving financing, management methods, the negotiation of PPP or more traditional contracts, preliminary studies, design, consultations, approval, delivery, or the management and exploitation of infrastructure projects, many legal issues must be dealt with. In addition to the usual challenges presented by any infrastructure project are the specific requirements associated with the sector of activity involved, whether that be transport, health care, energy, natural resources, or education. A multidisciplinary legal approach is essential to meeting a company’s varied needs in the best possible way.
