Frequently asked questions

What is NAICS 237120?

NAICS 237120 is the federal industry code for Oil & Gas Pipeline & Related Structures Construction. The Census Bureau maintains the NAICS taxonomy; federal contracting officers use it to classify solicitations and confirm bidder eligibility.

How do I bid on federal contracts as a small business in NAICS 237120?

Register your business in SAM.gov, get a UEI, and confirm your NAICS code matches the solicitation's primary NAICS. Then write a capability statement that maps your past performance to the work in the RFP. Themis automates the matching and gives you a free AI brief for every active opportunity.

Do I need a SAM.gov registration to bid?

Yes — every federal contract award above the micro-purchase threshold requires the vendor to have an active SAM.gov registration with a Unique Entity Identifier (UEI) and the relevant NAICS codes listed on the registration.
