2. Background

The work may include surveying and locating portions of the interstate boundary between the States of Texas and Oklahoma along the Red River of the South in accordance with that decision.

The Government is considering a single-award Indefinite Delivery/Indefinite Quantity (IDIQ) contract to support this effort. Specific survey tasks would be issued through individual task orders under the IDIQ.

Estimated Contract Ceiling: $25,000,000
Estimated Ordering Period: 5 years
