Summary

The Madrid Metro Extension project from 1995-2003 involved 56 km of new railway lines, with 38 km in tunnel, and 37 new stations. The project was completed at a cost of €28.2 million/km, with the underground section costing €41.3 million/km. The correct application of soil mechanics was crucial, and geotechnical expertise was retained to ensure safety and quality. EPB machines were used for tunnel construction, with a total of 39,195 meters built between 1999-2003. The project prioritized safety, with no cost or timing factors taking precedence over tunnel safety and quality. Contracts were fixed price with a bill of quantities to allow for easy pricing of additional work. The selection of contractors was undertaken with care, considering soft ground tunnelling experience and technical merits. A system was implemented to foresee problems and agree on solutions with contractors to avoid disputes.
