How much has Seres Engineering & Services LLC been awarded in government contracts?
$61M across 38 awards on RFPFinder, April 2019 to March 2026. That is the sum of the award records RFPFinder holds, not a complete history of Seres Engineering & Services LLC's government revenue.
Which prime contractors subcontract to Seres Engineering & Services LLC?
Prime contractors reported 1 subaward to Seres Engineering & Services LLC worth $100K on USAspending.gov, most from Aptim Federal Services, LLC ($100K). These are the subawards under prime contracts for the agencies and codes RFPFinder tracks.
Does Seres Engineering & Services LLC hold a GSA Schedule?
Yes. GSA eLibrary lists MAS contract 47QRAA18D00ES with 8 Special Item Numbers (541330ENG, 541380, 541620, 541715 and 561210FAC and more); the current option period runs to Aug 23, 2028. Federal agencies can place orders against it under FAR subpart 8.4, through GSA Advantage or GSA eBuy, instead of running a separate open-market buy.
How do I find Seres Engineering & Services LLC's UEI or CAGE code?
Seres Engineering & Services LLC's UEI on its federal awards is NBVMXMMBHYU3. Award records do not carry CAGE codes; search the UEI in SAM.gov's entity search to see the CAGE code and registration status.
Vendor totals add up the award records RFPFinder holds: federal contract awards from USAspending.gov for the agencies and codes behind open notices, and state and local awards from open-data contract registers and purchase-order files. They are not a vendor's complete government revenue, and a register that lists a contract ceiling or repeats a contract can overstate spend. Names are grouped across spellings ("Corp" and "Corporation"); each award links to its source record. Subcontracts are prime contractors' subaward reports on USAspending.gov for the prime awards behind the same agencies and codes, and GSA Schedule contracts come from GSA eLibrary's MAS contractor list; both are matched to vendors by name.
