Yes, choosing a helical pier estimate with a depth clause can lead to additional costs beyond the initial quote. A depth clause is a standard contract provision that allows for price adjustments if piers must be installed deeper than originally estimated to reach stable, load-bearing soil.
Key ways a depth clause impacts your final cost include:
- Additional Materials: Reaching greater depths requires more steel shaft sections and additional helix plates, which increases the material cost for that specific pier location.
- Increased Labor and Equipment Time: The deeper a pier must go—for instance, extending from a planned 15 feet to 25 feet due to unexpected soil layers—the more time and machinery use is required for installation.
- Proportional Price Increases: Under this clause, the total cost of the project rises proportionally with every additional foot of depth required.
Because subsurface soil conditions can be unpredictable, especially in areas with expansive clay or fill layers, these clauses act as a safeguard for contractors. It is highly recommended that property owners review the specific language of a depth clause carefully to prepare for potential cost overruns if stable strata are deeper than anticipated.
