MacLean Civil Products Teams with Rocky Mountain Steel Piering & Structural Services to Install (175) Helical Combo Piles for Distribution Center in Englewood, CO
Furthermore, the sandy clay soils were caving during drilling, requiring temporary casing be placed in order to complete drilling of concrete piers. Due to site access and ongoing business operations the drilling process would have been too invasive and cause too much disturbance to the facility that was in operation around the clock. Faced with these challenges the decision was made to utilized helical piles on the project.
The Helical Pile method was selected to be the sole method of foundation support for both additions.
One hundred seventy-five (175), 1-1/2” - 2-7/8” combo piles were installed to an average depth of 50 feet. The project installation was completed in two weeks, including mobilization and demobilization.

Red Bird Farms has been providing natural chicken products to Colorado since the 1940’s and have expanded their market reach to include other areas of the United States. The company is now family owned and operated. Red Bird recently decided to expand and construct two additions to their existing facility. The project needed to be completed without any interruption of the existing operations already ongoing at the facility which is in operation 24 hours a day.
Once the decision was made to increase the size of the distribution facility in Englewood, Colorado two additions were planned. One was a 3,500 square foot dry storage area, and the other was an 11,000 square foot Cooler and Freezer Building facility.

The proposed foundation support methods were:
- Footing (placed on over-excavated engineered controlled fill)
- Helical Piles
- Drilled Piers
Helical test piles were installed and a drilled test hole was excavated to develop a cost comparison to assist the owner in selecting the most economical method of foundation support for the project. In addition to cost, helical piles offered several advantages:
- Economical cost
- Increased production speed, faster project speed
- Project cleanliness
- Access advantages over the removal and reworking of the onsite soils
- Minimal noise, mud, and dust creation
- Ability for new support piles to be placed very close to existing structure
- The drilling operation would require temporary casing be placed and a large rig would be required to reach bearing soil depths
