Once performance deficiencies are identified, effective resolution requires more than corrective work—it requires a clear understanding of root cause and failure mechanism. Sentinel Secure Build provides engineering-driven remediation strategies and construction oversight to ensure that corrective actions are precise, coordinated, and aligned with the intended performance outcome.

​

Rather than relying on generalized fixes or exploratory demolition, Sentinel develops targeted solutions based on measured data, enabling efficient correction while minimizing disruption to the project.

​

Remediation Engineering Approach

Sentinel evaluates diagnostic testing results to determine the specific conditions contributing to performance degradation, including discontinuities in shielding, improper interface conditions, or unintended acoustic transmission paths. Corrective strategies are developed to directly address the identified failure mechanism—ensuring that remediation efforts are focused, effective, and constructible.

​

Typical RF Remediation Measures

• Restoring electrical continuity across seams and shielding interfaces

• Correcting grounding and bonding deficiencies

• Reworking penetrations and cable entry conditions

• Adjusting door alignment and conductive gasketing interfaces

• Installing supplemental conductive gasketing or localized shielding treatments

• Modifying mounting conditions that introduce unintended coupling paths

​

Typical Acoustic Remediation Measures

• Sealing and reworking penetrations and transmission pathways

• Improving door seals, thresholds, and gasketing performance

• Modifying or isolating mechanical duct systems

• Treating structural interfaces contributing to flanking paths

• Enhancing continuity at critical acoustic boundary transitions

​

Construction Oversight

Because remediation work often occurs at critical interfaces between trades, proper execution is essential to achieving the intended outcome. Sentinel provides active construction-phase support to ensure that corrective measures are implemented correctly and consistently.

​

Support includes:

• Coordination with responsible subcontractors
  to align corrective scope with trade responsibilities

• Technical guidance during remediation work
  ensuring that installation methods preserve shielding and acoustic integrity

• Verification of conditions prior to closure
  confirming that corrective work is complete and properly executed before assemblies are concealed

​

This approach ensures that remediation is completed correctly the first time, without introducing new deficiencies or unintended performance impacts.

​

Verification Testing & Performance Confirmation

Following implementation of corrective measures, Sentinel performs targeted retesting to confirm that deficiencies have been resolved and that performance aligns with expected outcomes.

​

This includes:

• Localized RF retesting at previously identified leakage points

• Whole-enclosure RF verification to confirm system-level shielding performance

• Acoustic retesting to validate improvements in speech containment

​

Verification testing ensures that:

• Corrective actions are effective and complete

• Measured performance aligns with planned attenuation and containment expectations

• The enclosure is properly prepared for final accreditation testing and review

​

By integrating remediation engineering and construction oversight into the project lifecycle, Sentinel ensures that performance deficiencies are resolved efficiently, precisely, and with minimal disruption.

This approach enables project teams to:

• Address issues while assemblies remain accessible

• Avoid costly late-stage rework and schedule impacts

• Implement targeted corrective actions instead of broad reconstruction

• Maintain coordination across trades during critical corrective work

• Improve confidence in successful accreditation outcomes
