About this IDV

Castro & Company, LLC, a minority-owned, Hispanic American-owned small business, was awarded a Multiple Award Blanket Purchase Agreement (BPA) valued at $5,000,000 by the National Science Foundation Office of the Inspector General (NSF-OIG) for audit services. The agreement, awarded on July 22, 2024, with an ultimate completion date of July 21, 2029, establishes Castro & Company as one of multiple awardees under this BPA vehicle. The contract utilizes no small business set-aside designation and leverages Castro & Company's General Services Administration Multiple Award Schedule (MAS) contract as the parent master vehicle. The firm, headquartered in Alexandria, Virginia, will deliver comprehensive audit services supporting the NSF-OIG's oversight and compliance responsibilities across the Foundation's grant portfolios and award recipients.

Under this BPA, Castro & Company has received multiple task order calls for specific audit engagements. The first task order, awarded September 13, 2024, with a ceiling of $100,584.36 and completion date of September 15, 2025, comprises an incurred cost audit of Georgetown University's National Science Foundation award. The second task order, awarded September 16, 2025, valued at $150,583.28 with completion scheduled for October 21, 2026, entails a subawardee audit of Arizona State University. Both task orders are issued as firm fixed-price BPA calls with performance locations in Alexandria, Virginia. These audit engagements support the NSF-OIG's financial oversight function by examining grant expenditures, internal controls, and compliance with federal requirements at major research institutions receiving NSF funding.
