Emisor Oriente & Metro 12

Mexico City, Mexico

Project: Emisor Oriente & Metro 12 Tunnels

Customer: Carso

The Emisor Orente is a 62 kilometer tunnel under construction outside of Mexico City that is being put in place to improve the municipal sewage system.  The project is using 6 TBMs from two separate manufacturers working in pressures up to 7 bar.

The Ballard team has been involved in multiple levels of this project.  We provided manlocks and material locks for multiple Tunnel Boring Machines (TBM’s), as well as multiple medical locks and shuttles.  Our experts provided extensive hyperbaric consultation to multiple prime contractors with widely varying levels of hyperbaric experience and needs.  In addition we provided multilingual Compressed Air Worker training in addition to supplying compressed air and mixed gas workers, manlock tenders, and other associated hyperbaric support personnel and equipment.  A complete tool change including the nose cone was performed by Ballard Compressed Air Workers.
