Pipe Size

127 feet of 54″ O. D. Permalok Steel Casing with 1.250″ walls

The Problem

Creating a storm sewer beneath the shallow cover of the highly trafficked Metra Rail Road without disrupting train operations. To avoid peak train schedules, tunneling could not commence until 8:00 p.m. on a Friday evening and had to be completed by 4:00 a.m. on Monday morning.

The Solution

To install the job’s linear foot requirements in such a short time frame, Midwest Mole and Glenbrook Excavating used an Akkerman conventional TBM to install the 54″ O. D. Permalok Steel Casing. Work was completed on schedule, with no disruptions to the Metra Rail system.
