The purpose of this notice is to satisfy the requirements of FAR Subpart 5.2.

This notice of intent is not a request for competitive quotes. However, all responsible parties may submit a technical statement describing their capability to perform the requirements of the attached Statement of Work (SOW), which shall be considered by the agency. Please note that merely stating that you are interested in the opportunity is not enough information to evaluate capability. No solicitation will be issued.

A determination not to compete this action based upon responses received is in the sole discretion of the Government. The NAICS code for this action is 541380 which is defined Testing Laboratories and Services, and the PSC is B517 Special Studies / Analysis - Geological.
