A specialized remediation and maintenance mitigation project for the banks tunnel. The Bank tunnel uniquely required the water intrusion and humidity conditions of the tunnel to stop effecting the pneumatic tube from continuous rust damage as well as the rest of the tunnel. Part of this was controlling the climate of the tunnel and advising for proper dehumidification levels to be reached. While we only worked below ground a different team worked above ground to seal cracks and what not which is another essential part of preventing damage to the tunnel underneath.
