Started from the specific award identified in our NAICS 541511 report (PIID 1605TA26F00001) and worked outward. USASpending’s award-detail API exposes each contract’s parent_award (the underlying IDV/BPA it was ordered against) — following that chain back showed the current task order sits under BPA 1605TA22A0001 (“Executive Order Support Services”), itself a successor to an older BPA, DOL-OPS-17-A-001, signed with Booz Allen in December 2016. Separately, a keyword search across all DOL contracts and all years for “FOREIGN LABOR APPLICATION GATEWAY” and related phrasing (not limited to any NAICS code or date range) surfaced every award that named the system directly, plus one 2018 predecessor contract for “OFLC case management” quality-assurance work that pre-dates the FLAG name. Subcontractor data comes from USASpending’s subaward records attached to the two most recent Booz Allen task orders.
