Tieback Retention

Home / Earth Retention Systems / Tieback Retention

If the depth of excavation near the retention is anticipated to exceed about 15 vertical feet, it is usually cost-effective to use ground anchors or structural bracing to minimize the required strength (and cost) of the piling elements used in the retention design.  Tiebacks can be installed to add additional capacity to a variety of earth retention systems, instead of a cantilevered wall.  Tiebacks are drilled horizontally at an angle and consist of a grouted steel element that is stressed and locked-off at design load.

FEDEX GSE Staging and Tug Road Expansion

St. Vincent Pacers Practice Facility

Project Location: Indianapolis, IN
Owner: Indiana Pacers
Architect/Engineer: Ratio Architects
Completion Year: 2016

  • 88 each tiebacks (30’ to 50’ long)
  • 50 each H piles (50’ long)
  • 14,000 SF piling and lagging retention

Overview

Beaty Construction was awarded the earth retention package on the Pacers Practice Facility project by the subcontract FA Wilhelm. Beaty installed over 14,000 square feet of h-pile and lagging earth retention in 3 separate pit locations which included 50 each h-piles (50’ long) and 88 tiebacks (30’ to 50’ long).

Highlights

  • 88 each tiebacks (30’ to 50’ long)

  • 14,000 SF piling and lagging retention

Port of Indiana- Jeffersonville Bulk Terminal

Project Location: Jeffersonville, IN
Owner: Port of Indiana
Completion Year: 2020

  • 38 ea- Drilled in piles
  • 48 ea – permanent tiebacks @ 75’ in length
  • 8,000 SF of lagging installation

Overview

Beaty was selected by Patrick Engineering to provide the best Earth Retention solution for a proposed 35’+ deep excavation. The earth retention was installed in close proximity to the Ohio River and was required to provide permanent lateral resistance loads of the adjacent railway within the facility. Three levels of permanent tie backs were installed inside the pit along with temporary bracing in the tunnel area.

Highlights

  • 38 ea- Drilled in piles
  • 48 ea – permanent tiebacks @ 75’ in length
  • 8,000 SF of lagging installation
  • 35’ excavation depth
