For a single-family new construction home in the Denver metro area, the average geotechnical soil report cost typically ranges from $1,500 to $3,000 in 2025. This investment provides the essential data structural engineers need to design stable foundations and specify helical pier depths.

Several factors influence the final pricing of a soil test:

• Number of Borings: Adding more borings increases both mobilization and laboratory testing costs. While repair projects may only need 2–3 borings, new construction often requires 4 or more.
• Site Access: Difficult conditions, such as sloped lots or limited access for drilling equipment, can add mobilization time and increase fees.
• Laboratory Testing Scope: Each additional test for moisture, density, or shear strength adds to the laboratory fees.
• Report Complexity: Comprehensive reports that include specific foundation recommendations for structural use cost more than basic screening-level assessments.

While basic screening reports may be available for $800 to $1,200, they often lack the detailed foundation design parameters required for a new build. Investing in a full report protects homeowners from the unpredictable and often catastrophic costs of future foundation failure caused by expansive soils.
