Concrete / Masonry Scanning Scope Argonne National Laboratory Argonne National Laboratory will engage a qualified contractor to perform non-destructive scanning of concrete and masonry substrates using Ground Penetrating Radar (GPR) and, when necessary, complementary detection technologies.

Scanning will be used to identify embedded elements within, but not limited to, the following substrates:

· Cast-in-place concrete slabs (on grade and elevated)

· Concrete walls, beams, columns, and decks

· Concrete masonry units (CMU)

· Precast concrete elements

· Structural toppings and overlays Embedded items to be identified may include reinforcing steel, post-tension cables, electrical conduits, mechanical piping, embedded anchors or plates, and detectable voids or anomalies.

Purpose Scanning is performed to reduce risk prior to blind penetrations, including drilling, coring, cutting, anchoring, or demolition activities. The intent of this effort is to:

· Prevent injury to personnel

· Prevent damage to structural, electrical, mechanical, or safety-critical systems or utility outages.

· Support the safe execution of construction and maintenance activities

· Improve coordination and decision-making in the field

· Maintain compliance with Argonne safety expectations and DOE contractor requirements Applicability and Scheduling Scanning services will be performed on an as-needed basis in support of:

· Construction projects

· Maintenance activities

· Inspections or modifications requiring penetration of concrete or masonry Work will be scheduled in coordination with Argonne Supervisor, Project Specialist or Technical Representative who initiated a Blind Penetration Permit (ANL-909). Emergency or short-notice scanning may be requested depending on operational needs.

Execution of Work

· Scanning shall be conducted by trained and experienced technicians using GPR and complementary detection methods (e.g., electromagnetic or ferrous detection).

· Scanning limits and boundaries shall be clearly defined prior to mobilization.

· Surface preparation, when required, shall be coordinated with Argonne Supervisor, Project Specialist or Technical Representative who initiated a Blind Penetration Permit (ANL-909)..

· Detected items shall be clearly marked on the surface using approved temporary marking methods and differentiated by object type where possible.

· Field sketches, photographs, annotated drawings, and summary reports shall be provided, including dates of scanning, areas scanned, methods used, findings, limitations, and technician qualifications.

· All work shall be performed in a manner that does not damage existing structures or finishes.

· Digital deliverables shall be provided as requested.

Roles and Responsibilities

· The Contractor is responsible for providing qualified personnel, appropriate equipment, scanning services, surface markings, and required documentation.

· Argonne National Laboratory Environmental, Safety & Health (ESH) representatives, project managers, or field supervision will coordinate site access, define scanning areas, and integrate findings into project planning and work control processes.

· The Contractor shall comply with all Argonne safety requirements, applicable OSHA standards, ANL Environmental, Safety & Health (ESH) expectations, and DOE contractor obligations, including permits, escorts, and restricted area coordination.
