About the company
Zg-Geo LTD, doing business as Zg-Geo, is a subcontractor providing geomechanical services to the Department of Energy for the Waste Isolation Pilot Plant (WIPP) and the National Transuranic Waste Program. Operating as a sole proprietorship limited liability company based in Littleton, Colorado, Zg-Geo has won seven sub-contract awards since January 2024, all routed through a single prime contractor relationship supporting DOE's transuranic waste operations and facility maintenance mission.
Zg-Geo operates exclusively as a subcontractor with no prime contract vehicles or direct awards to its name. All seven sub-awards are geomechanical services tasks tied to WIPP operations and the National Transuranic Waste Program under the Department of Energy Office of Environmental Management. The vendor's customer base shows complete concentration with DOE — 100% of awards fund the single customer agency. Award activity reflects early-stage or pilot engagement: six awards in 2024 (January through April, plus November and December) and one award in January 2025, with combined dollars obligated totaling $119 thousand across the seven sub-awards. The sub-awards date-clustered in early 2024 and late 2024 suggest periodic task call-downs rather than sustained continuous operations.
Zg-Geo's capability footprint is narrow and specialized. The vendor delivers geomechanical services — analysis, modeling, and technical support for underground facility performance, waste containment, and structural integrity — exclusively within the hazardous waste treatment and disposal sector (NAICS 7381). No prime contractor name is disclosed in the source; the sub-award descriptions reference only the broader WIPP operating mission without naming the parent contract vehicle or prime awardee. Zg-Geo's role is technical sub-support rather than prime program execution. The recent award history (most recent January 2025) and sub-award pattern suggest active engagement, but the sub-million-dollar obligated total, single-customer concentration, and specialist geomechanical scope indicate a narrow niche player focused on technical depth rather than program scale. The vendor carries no SBA designations visible in the source.
