Seaport-e & SeaPort NxG Small Business Highlights

Seaport in its design has small business utilization built into it. As a result of these efforts:

  • 85% of SeaPort contract holders are small businesses.
  • 44% of all spending obligations with Seaport went to small businesses or roughly ($2.5B out of $5.4B in spending)
  • Allows for small business set-asides whereby task order competitions are restricted to certain socio-economic categories such as WOSB, HUBZone, SDVOSB, and 8(a).
  • The standardization of the Seaport process benefits small businesses by reducing the administrative burden which generally gives larger contractors with specialized teams an advantage.


SeaPort Program Key Information

  • SeaPort refers to both a set of Indefinite Delivery Indefinite Quantity (IDIQ) Multiple Award Contracts (MACs) and an electronic platform to solicit, award and administer task orders.
  • SeaPort consists of SeaPort-e and SeaPort-NxG – which are separate sets of MACs utilizing the same electronic platform although with separate portals.
  • All task orders are competitively solicited, awarded, and administered using the SeaPort portal.
  • SeaPort is a Tier 1 federal contract. There are Tier 0-3 Federal Contracts with 0 not fitting into a category. As a Tier 1 contract SeaPort is Mandatory in its use by the agencies with which it presides over. Therefore, having a SeaPort contract will likely be the only way to obtain certain types of work from the Department of the Navy.
