The CST is responsible for monitoring construction activities, inspecting materials and equipment, identifying potential security anomalies, and helping prevent the introduction of unauthorized technical devices or materials into secure construction areas. Working under the direction of the Site Security Program Manager (SSPM), Lead CST, and designated site security leadership, the CST performs construction surveillance in accordance with the approved Construction Security Plan (CSP), Standard Operating Procedures (SOPs), Special Instructions, approved drawings and specifications, and applicable U.S. Government security requirements.

Primary Responsibilities

Monitor, observe, and interact with uncleared construction personnel while work is being performed to prevent or detect the introduction of electronic, electrical, mechanical, or other hostile surveillance devices.

Inspect construction materials, equipment, furnishings, packages, bags, boxes, crates, vehicles, and other items entering secure construction areas.

Operate X-ray equipment and other approved technical inspection tools in accordance with established procedures.

Review construction drawings, specifications, and applicable technical documentation to verify construction activities are consistent with approved requirements.

Identify and report unauthorized changes, unusual construction methods, concealed spaces, suspicious modifications, or other anomalies that could compromise security.

Conduct risk-based surveillance and inspections based on construction activities, work sequencing, workforce composition, and identified technical concerns.

Assess potential locations and methods that could be used to conceal clandestine technical surveillance devices or introduce unauthorized materials.

Apply knowledge of Technical Surveillance Countermeasures (TSCM), PHOTOINT, IMINT, counterintelligence principles, construction security surveillance, and technical threat awareness.

Recognize suspicious behavior, unauthorized materials, unusual components, potential technical penetrations, or other conditions requiring further review.

Support personnel and vehicle searches, security escorts, access-control functions, and related security duties when assigned.

Construction Surveillance & Technical Requirements

Maintain working knowledge of construction disciplines including civil, architectural, structural, mechanical, electrical, telecommunications, and electronic systems sufficient to identify potential security concerns.

Interpret construction drawings, blueprints, and technical specifications and recognize conditions that could conceal unauthorized modifications or an ulterior purpose.

Understand common construction terminology, procedures, practices, sequencing, and workmanship.

Understand methods that may be used to emplace technical penetrations, unauthorized materials, or clandestine devices.

Maintain familiarity with technical security devices, systems, monitoring equipment, and other technologies associated with secure construction.

Apply construction security surveillance, personnel search, vehicle search, and static security techniques as required.

Maintain awareness of the security requirements applicable to different areas of the construction site.

Exercise independent judgment and initiative while performing assigned surveillance duties with minimal supervision.
