The Regie Autonome des Transports Parisiens (RATP) has been engaged in construction of a new "Regional Express Rail" transit system and in extension of the existing Paris Metro system. Many differing construction methods have had to be utilized because of the variety of soil and geological conditions. Construction under many of the city's landmarks produced other problems. Each new work has been analyzed and several solutions are studied to find the most suitable solution. After technical and economic analysis, contracts are let. This is the first of two installments.
