The Department of the Interior Bureau of Reclamation awarded a $20,000 firm fixed price purchase order to Interworks Consulting LLC, located in Loveland, Colorado. The award is to provide SnowTran 3D software licenses for incorporation into the Bureau's existing SnowModel application. The original solicitation indicated this was a single-source award as Interworks Consulting is the developer of the proprietary SnowTran 3D software. Providing these licenses from any other source would not guarantee continuity with the Bureau's historical snow modeling data. No set-aside was used for this award made under the authority of the Federal Acquisition Regulation allowing for other than full and open competition when only one source is reasonably available.
