Editor’s note: Often, the world we see is just the tip of the ice burg. This spring, PSU advanced reporting student Addie Hinterweger explored the network of underground tunnels beneath the campus and learned about plans the university has for repair and replacement.
The oldest section of the steam tunnel system beneath Pittsburg State University's main campus is slated for replacement, with an engineering firm hired to design a plan for bidding later this year.
A survey conducted by Henderson Engineers in December 2020 at the request of PSU’s Office of Planning, Construction, and Design evaluated the condition of the steam tunnels, identified underground issues, and recommended action. Lindell Haverstic, architect and director of PCD, said the original brick tunnels, constructed in 1914, are in the most critical condition.
"The old brick tunnels are in dire need of replacement," Haverstic said. "The original brick materials are fragile, with displaced or missing mortar in numerous locations. Groundwater infiltration compromises the tunnels' condition, the lifespan of utilities within and the ability of maintenance crews to operate effectively."
Similarly, Tim Senecaut, director of facility operations at PSU, emphasized that regardless of age, the tunnels will consistently require repairs due to water infiltration.
"The tunnels are aging, and we have to contend with that reality," Senecaut said. "Water will inevitably seep into the tunnels, necessitating repairs over time."
In 2013, during the construction of the Overman Student Center, most of the steam tunnels were replaced with concrete. While the survey categorized these areas as "not critical," it recommended replacement within the next two decades, highlighting the ongoing maintenance needs.
The renovation of the brick tunnels is estimated to cost $1.5 million, covering design, construction, contingency and additional project expenses. The Office of Planning, Construction, and Design is expected to finalize a plan this spring, with construction starting thereafter.
