The Gardens of Elm Grove Sub-Division

Location: Lake McQueeney, TX
Engineer: Primero Engineering, Inc.
General Contractor: DRB Enterprises, LTD
Helix Steel Pier Contractor: South Coast Helix Foundations, Inc.

Project:

Dixie Anchoring System Steel Piers were installed as a deep foundation system to support a new house. The new housing sub-division is located along the shore of Lake McQueeney. The Engineer and Contractor decided to use helix steel piers rather than installing a very costly concrete piering system. The concrete piers required casing due to very difficult soil conditions, therefore, the concrete piers were not economically feasible compared to the helix steel pier system. South Coast Helix Foundations, Inc. installed twenty-eight (28), 1 ½" x 1 ½" rounded corner solid square shaft helix steel pier with a single 8" diameter bearing plate lead section, at fourteen (14) column locations (two (2) helix steel piers at each location). Each helix steel pier required an installation torque of 5,000 ft-lb (25,000 lbs. working load). The pair of helix steel piers were necessary to resist 32,000 lbs. vertical load, 5,200 lbs. lateral load and a 38,000 ft-lb over turning moment. The helix steel piers were advanced to lengths of twenty-five (25) and thirty (30) feet at approximately a ten (10) degree angle from vertical. A top attachment bracket for new construction (plate series) was bolted to the end of each helix steel pier and will be cast into a concrete pier cap. The local building codes require the house to be elevated above the flood plain, therefore, a steel support column will then be bolted to the concrete pier cap that will extend approximately fifteen (15) feet above the lower ground surface. The helix steel pier portion of the project was completed in less than two (2) days!

U.S. Coast Guard New Foundation

Location: Freeport, Texas
Structural Engineer: U.S. Coast Guard
General Contractor: Jacquet Construction Services, LLC
Helix Steel Pier Contractor: South Coast Helix Foundations, Inc.

Project:

Dixie Anchoring System Steel Piers were installed to support a new foundation system. The project consisted of installing a new foundation below an existing building with only twelve (12) feet of vertical clearance. South Coast Helix Foundations, Inc. installed twenty (20) helix steel piers each to carry a 12,000 lb load required by the U.S Coast Guard Engineer. 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 depths of twenty-seven (27) and thirty-two (32) feet. The top attachment bracket for new construction (plate series) was then bolted to the top of the helix steel piers. The project was completed in two (2) days!

Jefferson HS Technology Renovations — SAISD

Location: San Antonio, Texas
Structural Engineer: Robert Barrera, P.E., Jaster-Quintanilla San Antonio, LLP
General Contractor: Browning Construction Co.
Helix Steel Pier Contractor: South Coast Helix Foundations, Inc.

Project:

Dixie Anchoring System Helix Steel Piers were installed using portable hand-held equipment to support a new concrete ramp and walkway between two (2) existing buildings with limited access. South Coast Helix Foundations, Inc. installed thirteen (13) helix steel piers each carrying either 15,000 or 21,000 lb loads. Each helix steel pier was a 1 ½" x 1 ½" rounded corner solid square steel shaft with a double lead section consisting of an 8" & 10" diameter bearing plates. These helix steel piers were advanced to depths of fifteen (15) and twenty (20) feet. The top attachments, for new construction (plate series), was then bolted to the top of the helix steel piers and will be cast into concrete for this new access.
