Kickapoo Casino, Mezzanine Support Columns

Location: Eagle Pass, Texas
Structural Engineer: Schwab Structural Engineering, Inc., John Schwab, P.E.
Geotechnical Engineer: Zapata & Associates
Helix Steel Pier Contractor: South Coast Helix Foundations, Inc.

Project:

Dixie Anchoring System Steel Piers were installed to support a new interior mezzanine floor. The project consisted of four (4) column supports inside an existing building with limited vertical clearance. At each column support, the concrete floor was saw cut and was excavated 18" below the top of the concrete floor. South Coast Helix Foundations, Inc. installed eight (8) helix steel piers each to carry between 20,000 lb to 25,000 lb load. Each helix steel pier was a 1 ½" x 1 ½" rounded corner solid square steel shaft with a single lead section consisting of an 8" diameter bearing plate. The top attachment bracket for new construction (plate series) was then bolted to the top of the helix steel piers and will be cast into a reinforced concrete pier cap. A steel support column will then be bolted to the concrete pier cap for the new mezzanine floor. The project was completed in one (1) day!

Helix Steel Pier Contractor: South Coast Helix Foundations, Inc.

Project:

Dixie Anchoring System Steel Piers were installed as tie-backs to stabilize two (2) large concrete retaining walls built in 1912, that were experiencing lateral movements. Twenty-five (25) helix steel piers were located at various points along the two (2) concrete walls. Each helix steel pier was a 1 ½" x 1 ½" rounded corner solid square steel shaft with a triple lead section consisting of an 8", 10" & 12" diameter bearing plates. The helix steel piers were advanced to various lengths ranging from seven (7) to twenty- two (22) feet. Threaded adapters were then bolted to the top of the helix steel piers. All of the helix steel piers were load tested to 30 kips. The cored holes were filled with non-shrink grout and then galvanized steel whalers (back to back 12" channels) were attached to the threaded adapters (along the outside of the each wall).

Sam Houston Service Building

Location: Edinburg, Texas
Structural Engineer: Solorio & Associates, Simon Solorio, P.E.
Helix Steel Pier Contractor: South Coast Helix Foundations, Inc.

Project:

A historical building was experiencing differential foundation movement. Other underpinning methods previously used to stabilize the foundation had failed. The project engineer and contractor decided to install helix steel piers after learning about the Dixie Anchoring Systems in an ASCE seminar presented by South Coast Helix Foundations, Inc. Seven (7) helix steel piers were installed at two (2) different locations under the structure. Each helix steel pier was a 1 ½" x 1 ½" rounded corner solid square steel shaft with a single lead section having a 10" diameter bearing plate. The helix steel piers were installed to a depth of seventeen (17) feet. A standard underpinning bracket was attached to the concrete grade beam which will transfer the foundation load to the helix steel pier in order to stabilize the structure from future settlement. Each helix steel pier installation torque was monitored and verified by using a shear pin torque indicator. The helix steel piers were loaded to 10 kips of vertical load. The installation of the helix steel piers were completed by a certified crew in one (1) day.
