Steam Tunnel Structure Repairs – Architecture/Engineer Selection

Steam Tunnel Structure Repairs, NC State Project #201720058

Description:    NC State University has a series of 11 interconnected underground tunnels totaling approximately 1 mile in length that house steam and high pressure condensate piping that provide heat and process loads for campus office, laboratory, and classroom buildings.  The tunnels are made of concrete and are in need of various repairs. This project will prepare a design to repair the following conditions:

1.  Spalls and delaminations without corroded rebar;
2.  Spalls and delaminations with corroded rebar;
3.  Spot treatment of rebar with zero inch cover;
4.  Epoxy crack sealing by pressure injection;
5.  Reinforcing of walls and ceilings that are showing deterioration and local   failure; and,
6.  Complete tunnel reinforcement due to multiple structural failures.
