Solieng Inc.

Solieng Inc., doing business as Solieng, holds a single GSA Multiple Award Schedule contract as a prime contractor, offering professional engineering services to civilian federal agencies through a nationwide catalog vehicle. Solieng is a woman-owned small business and self-certified small disadvantaged business based in Sterling, Virginia, competing on full-and-open (non-set-aside) GSA Schedule terms.

The vendor's federal footprint consists of a March 2025 GSA Federal Supply Schedule contract with a $400 thousand ceiling running through March 2030, covering engineering services under three Special Item Numbers: Engineering Services (541330ENG), Engineering System Design and Integration Services (541420), and Engineering Research and Development and Strategic Planning (541715). The published labor portfolio includes a single category—Aerospace Engineer with a PhD and 23 years of experience—priced at $119.19 per hour. Orders under the schedule range from $100 to $1 million, with geographic coverage across all 50 states, the District of Columbia, and U.S. territories. The contract allows federal agencies to place task orders directly against Solieng's published rates without separate competitive action.

As of the source date, Solieng reports no subcontractor work and no federal grant awards. The vendor has not secured task orders or delivery orders against the GSA Schedule contract in the source data window; the ceiling of $400 thousand represents the vendor's maximum ordering authority under the vehicle, not invoiced or obligated value. With only one award across a single contract vehicle and no customer agencies beyond GSA Federal Acquisition Service in the source, Solieng is in the early stages of federal market penetration. The absence of prior federal contract experience, subcontracting relationships, or active task-order activity positions Solieng as a newly registered GSA Schedule vendor with no demonstrated federal revenue baseline. Growth trajectory depends on federal agencies discovering and tasking the contract; the five-year performance period (2025–2030) allows Solieng to accumulate volume, but competitive positioning against established engineering-services contractors on the same schedule remains untested by the source data.
