While helical piers are often preferred in the Colorado Front Range due to their speed and performance in expansive clay, push piers remain a viable and time-tested solution for specific scenarios.

According to the provided guide, you should consider using push piers when:

• Heavy Commercial Loads are Present: Push piers are often better suited for very heavy commercial applications compared to standard residential loads.
• Deep Excavation is Already Planned: If your project site already involves planned deep excavation, installing push piers can be a practical choice.
• Sites Feature Stable, Compact Soils: Push piers can be particularly cost-effective in sites with compact, shallow soils where the pier can be driven to refusal at competent bearing strata.
• Historic Renovations Require Specific Support: They are sometimes preferred for historic renovations that require minimal soil disturbance below grade.
• Compression Loads are High: This method is effective when stable soils are available to support high compression loads through end-bearing capacity.

However, it is important to note that push pier installation typically involves a slower timeline because it requires excavation and concrete curing. For a definitive diagnosis, you should consult a licensed structural engineer to evaluate your specific site conditions and load requirements.
