Budget estimate

$200,000 – $800,000

Based on typical county contracts for geotechnical and materials testing, a multi‑year service agreement for a medium‑size county often ranges between $200,000 and $800,000 in total contract value. The lower bound reflects a modest testing volume (limited to a few projects), while the upper bound assumes a broader portfolio of capital projects with extensive laboratory work, specialized testing, and reporting requirements.
