SOURCES SOUGHT NOTICE Hazards Associated with Anti‑Ram Perimeters U.S. Department of State (DOS) Bureau of Diplomatic Security (DS) Physical Security Division (PSD) Research and Development Branch (RD) This is a Sources Sought Notice for market research purposes only. This is NOT a solicitation, request for proposals, or request for quotes. No contract will be awarded from this announcement. The Government will not reimburse any costs for responding. The purpose of this notice is to determine whether responsible small business concerns (8(a), HUBZone, SDVOSB, WOSB/EDWOSB, and other small‑business categories) possess the capabilities and interest to perform the work described in the attached Statement of Work (SOW) titled “Hazards Associated with Anti‑Ram Perimeters” dated 22 May 2026. 1. DESCRIPTION OF REQUIREMENT The Bureau of Diplomatic Security's Physical Security Division Research & Development Branch (DS/PSD/RD) seeks contractor support to conduct large‑scale blast testing and fragmentation characterization of Department anti‑ram perimeter systems subjected to a simulated Vehicle Borne Improvised Explosive Device (VBIED) attack. Work includes: • Phase 1: Debris characterization of baseline anti‑ram barriers under a 2,000‑lb TNT‑equivalent blast. • Phase 2: Debris characterization of modified systems using proposed opaque claddings to evaluate potential hazard‑mitigation properties. • High‑speed videography, instrumentation planning, dynamic data collection, post‑blast debris assessment, and detailed reporting. • Generation of updated or new engineering drawings for inclusion in the DOS Physical Security Handbook (Red Book). • Monthly progress reporting. Government‑furnished information includes test standards, historical test data, and drawing templates. Anticipated NAICS: 541715 – Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) (If your agency prefers a different NAICS, I can modify.) Estimated Period of Performance: Up to 24 months. Accelerated schedules are preferred. 2. REQUESTED CAPABILITY INFORMATION Interested small‑business concerns shall submit a capability statement addressing their ability to perform the following requirements: A.
