Double the Trouble – Crossing the Sunrail Corridor with a 72-inch Stacked Jack and Bore

Description:

Crossing the narrow and heavily congested Sunrail corridor in downtown Orlando with two large diameter pipes was not feasible until a custom 72-inch stacked jack and bore casing concept was designed. The Orlando Utilities Commission (OUC) and City of Orlando Joint Use project required that OUC’s 24-inch raw water main and 20-inch potable water main be constructed via a trenchless installation under the Sunrail corridor within Highland Avenue in Orlando, Florida; however, the right-of way (ROW) is only 30-feet wide and heavily congested with existing utility facilities.

Nature of Project:
  • New Products and Method
  • Trenchless Research and Innovation
Trenchless Technology Involved:
  • Auger/Case Boring
