Analysis Notes
Place of Performance Largest percentage of work under issued task orders completed at: New Mexico 88349 United States.
Sole Source This IDC was awarded sole source to Thornton Tomasetti because delay in acquisition (typically due to disaster response) could result in financial or bodily injury (FAR 6.302-6).
Ceiling Exceeded Total obligated funds of $20,320,679 has exceeded the reported contract ceiling of $20,000,000. This may prevent future funds from being obligated to this indefinite delivery contract. Note, however, that the government can often amend the ceiling to allow for additional awards or in some cases may not have properly updated the ceiling in public records.
Direct Award $20,000,000.00 was obligated directly to this IDV and does not have an associated task order.
