This project is located at the RTA Airport Rapid Station and surrounding area. The pump room at the entrance to the GCRTA Airport Tunnel is experiencing water intrusion which is in need of repair. Water is also leaking through joints in the airport tunnel ceiling which is causing damage to the rail tracks through electrolysis. Finally, an air duct needs repaired and the void surrounding the duct needs excavated and backfilled. This void is continually getting larger and needs to be corrected before it creates further damage.
