To determine if your quote includes a no depth clause (or conversely, contains a clause that allows for price adjustments), you should carefully review the contract language regarding soil conditions and pier depth.

Based on industry standards and ACN Construction’s practices, here is how you can identify these terms:

• Review the contract for ‘Depth Clauses’: Standard contracts often include a depth clause that allows the contractor to adjust the pricing if installers must go deeper than originally estimated to reach stable, load-bearing soil.
• Check for ‘Per Foot’ pricing: Look for language stating that each additional foot of depth beyond a specific limit will trigger extra charges for material (steel shaft sections and helix plates), labor, and equipment time.
• Analyze the ‘Base Price’: A quote might only reflect the cost for a standard depth (e.g., 15 feet). If the soil profile requires extending to 25 feet, a depth clause ensures you are billed for that additional work.
• Look for Itemized Bids: Demand a detailed, line-item estimate. This transparency helps you see if mobilization, engineering, and specific depth limits are clearly defined or if the quote is a flat fee regardless of depth.

To ensure complete financial predictability, ask your contractor specifically if the quote is a "fixed-price" agreement or if it includes a depth clause that could increase the helical pier cost per pier due to unforeseen subsurface conditions.
