Sources and method

Figures on this page are computed from public federal award records. Numbers are never estimated or generated; where a figure is withheld, the reason is stated rather than filled in.

Comparable awards are scored on benchmark category, product and service code, industry code, buyer, place, recency, and contract type. Rubric version comparables@2026.08.1.

  1. 1Notice fields come from the SAM.gov contract opportunities record last seen Sep 5, 2026. SAM.gov remains authoritative.
  2. 2Computed from 50 completed federal awards using comparables@2026.08.1, as of Aug 17, 2026. Award values are neither unit prices nor a forecast.

Note 1 covers the solicitation record; note 2 covers the comparable range. No synthetic FAQ or inferred solicitation value is published.
