Project Description:

  • Installation of 1050 lf of 8x8 pre-cast tunnel system and cast in place access nodes, primarily in Sandstone.
  • Installation of Sanitary Sewer, Storm Drain and Waterline.
  • Construction of utility tunnel, utilidor, duct bank and electrical systems, pile support systems, pedestrian walkways and temporary parking.
  • Complete re-build of the access road into the campus, and resurfacing of the service road including demolition, site clearing and excavation, erosion and sedimentation control, drainage improvements and landscaping.
  • IMCO used one of the largest Trenchers in North America to perform the rock excavation of the tunnel and the deep sanitary sewer line.


The tunnel houses a high pressure steam line used by WWU for heating the campus and houses all of the primary electrical system for WWU. Campus activities were not interrupted by conventional rock blasting. By trenching, the work was performed more safely.
