Yes, the type of pier selected — push pier or helical pier — significantly impacts the overall project cost due to differences in material manufacturing, equipment requirements, and installation depth.

According to the provided data, the cost trade-offs include:

• Push Piers: These generally require a higher upfront investment. They are more expensive because they must be driven deep into the ground until they reach load-bearing bedrock or dense shale. They also require heavy hydraulic equipment, such as 1,000-pound rams and cranes, which increases logistical costs.
• Helical Piers: These are often more affordable per unit, especially for lighter loads. Because they use a portable torque motor and can achieve stability in shallower, looser soil without necessarily reaching bedrock, they often reduce labor time and material runs.

Cost and Complexity Comparison:

• Material Costs: Helical piers have higher manufacturing complexity due to welded helices and galvanization, resulting in a typical cost of $180 – $300 per linear foot. Push piers use simpler steel casing and concrete, costing approximately $150 – $250 per linear foot.
• Installation Impact: Helical piers are ideal for tight spaces and require minimal excavation. In contrast, push piers require large excavated pits, which adds to the cost of landscaping disturbance and site preparation.
• Load Requirements: While more expensive, push piers provide higher load capacities (8,000–12,000 lbs) suitable for heavy commercial structures, whereas helical piers are more cost-effective for single-story additions or lighter residential loads (2,000–8,000 lbs).
