From Facility Strategy to Validated Performance
Sentinel supports mission-critical and secure facilities across the project lifecycle, from early facility strategy and planning through design, construction, performance verification, and accreditation.
Mission Investment Strategy
TI planning, contract-aligned facility investment, cost-recovery strategy
Secure Facility Strategy
SCIF/OSS planning, ICD 705 coordination, accreditation strategy
Project Delivery
Design, construction, risk, schedule, and occupancy coordination
Sentinel supports containment planning by either developing the design and specifying shielding materials and installation methods, or by reviewing existing designs to confirm alignment with RF and acoustic performance requirements.
By resolving these conditions early, projects avoid downstream performance gaps, rework, and accreditation risk.
Containment performance cannot be assumed—it must be measured.
Sentinel conducts construction-phase RF and acoustic diagnostic testing to evaluate the enclosure as a complete system, identifying deficiencies that are otherwise undetectable through inspection alone.
This establishes a verified performance baseline prior to final accreditation.
Sentinel performs construction-phase acoustic testing to identify flanking paths and containment deficiencies while assemblies remain accessible, followed by formal certification testing to validate completed enclosure performance. Testing evaluates walls, doors, penetrations, and mechanical systems in line with ASTM E336 standards and provides defensible documentation aligned with accreditation requirements for both Sound Group 3 and 4.
Sentinel delivers defensible, accreditation-aligned documentation validating containment performance. Through final acoustic certification and RF containment verification, Sentinel produces clear, structured documentation of test methods, equipment, and measured performance—aligned with recognized practices (ASTM, IEEE 299) and formatted to support AO/CTTA accreditation review.
