• Secure Facility Management:
  Directly managing construction projects for cleared facilities, demonstrating a thorough understanding of security requirements, controlled access, and material handling procedures for such sites.
• SCIF Construction Expertise:
  Oversee all phases of SCIF (Sensitive Compartmented Information Facility) construction, including physical security measures, acoustic controls, and compliance with all relevant Intelligence Community Directives (ICD).
• Network Technology Integration:
  Coordinate and supervise the installation, termination, and testing of complex network technology infrastructure, including structured cabling, server room build-outs, and communication systems, ensuring readiness for final systems integration.
• Schedule and Safety:
  Maintain a master construction schedule, proactively identify potential delays, and implement corrective actions. Enforce a strict, zero-tolerance safety program on-site, ensuring compliance with OSHA and local safety regulations.
• Team Leadership:
  Supervise and mentor on-site staff, including foremen, skilled tradespeople, and subcontractors, fostering a collaborative and high-performing work environment.
• Documentation and Reporting:
  Prepare daily reports, track project progress, manage change orders, and maintain comprehensive records of site activities, inspections, and materials.
