Stiver Engineering Helps Complete a Challenging Tunneling Project in Downtown Houston

As seen in Engineering News-Record Texas Louisiana (ENR Texas Louisiana), Harper Brothers Construction and HB Trenchless recently launched a new Akkerman 96-in. earth pressure balance tunnel-boring machine as part of the Houston Public Works Surface Water Transmission Program. The machine will excavate an 874-ft-long tunnel under IH-69 (US-59) in downtown Houston.

Stiver Engineering provided shoring design services for this project including secant pile shaft design for the launch and receiving shafts as well as designs for the breakout structure for the Akkerman TBM.

A remarkable photo taken by photographer and drone operator Will Byland, clearly captures a bird’s eye view of the impressive 75-ft-deep shaft.
