Budget estimate

$50,000 – $200,000

No monetary value is disclosed in the solicitation. Based on typical costs for a full drive‑assembly rebuild of a gravity thickener clarifier (including parts, labor, testing, and project management), a reasonable estimate ranges from $50,000 for a straightforward repair using standard parts to $200,000 for a complex rebuild requiring custom‑fabricated components, extended labor hours, and possible downtime mitigation. Factors influencing the final amount include the condition of existing equipment, availability of OEM parts, travel and mobilization costs, and any required engineering support.
