Concrete Scanning for Campus Safety: A Planning Guide for Georgia Facilities
Campus renovation and maintenance work rarely happens in an empty, uncomplicated building. A planned core, anchor, saw cut, slab removal, or demolition area may sit near classrooms, labs, residence halls, utilities, and people who still need access to the facility. Concrete scanning for campus safety gives Georgia facility teams and project contractors a way to investigate the work area before intrusive work begins.

This guide focuses on planning, coordination, and scope. It does not replace the campus owner's safety program, engineering direction, utility-owner coordination, shutdown procedures, or the contractor's site-specific safety plan. The goal is to help the right people ask better questions before the first cut or drill.
What makes concrete scanning for campus safety different?
Concrete scanning for campus safety is a pre-work planning step that helps campus teams and contractors understand what may be embedded in a concrete slab, wall, deck, or foundation before drilling, coring, sawing, anchoring, or selective demolition. The campus setting adds occupied-building coordination, restricted access, incomplete records, protection of adjacent spaces, and schedule constraints to the technical scanning question.
On a private campus, drawings and utility records may not reflect every renovation, rerouted conduit, abandoned line, or structural change. A scan can help the project team investigate the specific area tied to the planned work instead of treating an old plan set as a complete picture. The University of Georgia campus GPR survey report illustrates how a campus project can use a defined research plan, method, results, and interpretation rather than an informal visual check.
The purpose is not to produce a blanket promise that every hidden object will be found. It is to create better field information for a defined decision, then communicate that information to the people who will perform and supervise the next phase.
When should a Georgia facility schedule a concrete scan?
Schedule a concrete scan before any planned activity that may penetrate, remove, load, or materially disturb concrete and where embedded conditions could change the safe method. The earlier the scan is included in the work plan, the more opportunity the team has to adjust the location, sequence, access window, or shutdown plan.
A scan may be appropriate before:
Core drilling for plumbing, electrical, fire protection, HVAC, or data pathways.
Saw cutting a slab for a trench, drain, doorway, equipment pad, or utility route.
Installing anchors, supports, railings, equipment, or other penetrations.
Removing a section of slab, wall, deck, or concrete enclosure during renovation.
Selective demolition near reinforcement, post-tensioning components, conduits, piping, or voids.
Renovating older facilities where as-built drawings are incomplete or conditions have changed.
Working in an occupied building where an avoidable outage, closure, or repair would affect classes, research, housing, or operations.
Concrete scanning is one part of the investigation. If work includes excavation or ground disturbance outside a building, the project team also needs a separate underground-utility process. OSHA's construction excavation requirements address determining the estimated location of underground installations before opening an excavation. A concrete scan should not be presented as a replacement for that process or for direct coordination with utility owners.
Clear field markings and a shared plan help connect scan findings to the next campus construction task.
What information should a facilities team provide before the scan?
A useful scan request describes the decision the project must make, the exact work area, the planned penetration or removal, site constraints, and the people who need the result. A defined request helps the scanning contractor set a practical boundary and helps the facilities team avoid paying for an investigation that does not answer the field question.
Before requesting a quote, gather as much of the following as the project can provide:
Project purpose: Explain whether the work involves a core, saw cut, anchor, trench, wall opening, slab removal, or demolition.
Location: Identify the building, floor, room or grid, approximate dimensions, elevation, and accessible surfaces.
Planned work: Mark proposed cut lines, core points, anchor locations, expected depth, and the date the next trade needs the area.
Available records: Share drawings, prior renovation information, utility maps, structural notes, and known changes without treating them as proof of current conditions.
Access conditions: Note occupied rooms, restricted areas, furniture, equipment, finishes, standing water, coatings, and any required escort or background process.
Coordination needs: Identify the owner representative, superintendent, engineer, safety contact, and trade foreman who will review the findings.
Deliverable expectations: State whether the project needs field markings, photos, a sketch, a written summary, or another agreed handoff format.
For larger renovation programs, separate scan areas by building, floor, phase, and decision. This makes it easier to match each finding to the work package and to rescan an area when the design or penetration location changes.
How does a campus-ready scan fit into the project sequence?
A campus-ready scanning workflow connects planning, field investigation, interpretation, marking, review, and execution. The scan should occur early enough for the project team to act on the findings, not as a last-minute formality after the cutting crew and access window are already committed.
Define the intrusive work. Identify exactly what the next trade intends to cut, drill, core, anchor, remove, or demolish.
Review records and site conditions. Compare available plans with the current space and note missing information, renovations, finishes, equipment, and access restrictions.
Set the scan boundary. Include enough surrounding area to evaluate the proposed work and any reasonable adjustment zone. The boundary should be agreed before mobilization.
Scan and interpret the target area. An experienced operator reviews the returning signals and identifies detectable features that may affect the planned work. GPR findings require interpretation, not just a pass over the surface.
Mark and document findings. Field markings should be clear to the people setting out the next task. Photos, sketches, or other documentation should identify the area and its relationship to the planned work.
Hold a pre-work review. The superintendent, facilities representative, engineer when applicable, safety contact, and executing trade should understand what was found, what remains uncertain, and what changes are required.
Execute under the approved plan. If the proposed location changes, the team should determine whether the new area needs additional investigation before work continues.
All Pro Demolition's Georgia GPR utility-strike planning guide covers the broader scan, interpretation, and marking workflow. This campus-focused application adds the coordination needed when the work area is part of a living facility rather than an isolated jobsite.
What can GPR help identify, and what can it not confirm?
Ground-penetrating radar can help identify patterns and anomalies associated with features such as reinforcing steel, post-tensioning components, conduits, piping, voids, and other subsurface conditions. Results depend on the material, depth, moisture, reinforcement density, access, surface condition, equipment, and operator interpretation. GPR is valuable evidence, not an unconditional guarantee.
For campus planning, the most useful question is not simply, "Can GPR see through this concrete?" It is, "What decision does the project need to make, and what information can a scan provide about that decision?" For example, the team may need to know whether a proposed core intersects a dense reinforcement pattern, whether a saw-cut route crosses a detectable conduit, or whether the planned work area needs engineering review before proceeding.
GPR may have limits when surfaces are heavily congested, wet, coated, inaccessible, unusually thick, or affected by other conditions. It may not identify every material or establish whether a utility is energized. A responsible scope should identify limitations and the additional verification or coordination the campus project requires.

How should occupied-building safety shape the plan?
Occupied campus work should treat the scan as part of a wider protection and communication plan. The facilities team should coordinate access, noise, dust, barriers, egress, shutdowns, sensitive rooms, and the timing of intrusive work with the contractor and affected building users.
Concrete scanning itself is nondestructive, but the work that follows may create dust, noise, vibration, water, debris, or an interruption to building systems. A campus plan should address:
Whether the area can be isolated during scanning and subsequent cutting or drilling.
How students, staff, visitors, researchers, and other trades will be kept outside the work zone.
Whether the planned work affects fire protection, electrical service, plumbing, data, security, or environmental controls.
What dust-control and housekeeping measures apply to the following concrete task.
Who can authorize a shutdown, change a penetration location, or stop work when field conditions differ from the plan.
How findings and limitations will be handed to the night-shift, facilities, or trade team that performs the work later.
Concrete cutting and drilling can also create respirable crystalline silica exposure. OSHA's construction silica standard includes requirements and specified control methods for covered tasks. The project contractor remains responsible for applying the requirements that fit the work, conditions, and employer safety program. A scan helps with subsurface planning, but it is not a silica-control plan.
For related execution planning, see All Pro Demolition's guide to GPR safety in concrete scanning and cutting and its Georgia concrete core drilling field guide.
What should be included in the scan handoff?
The handoff should make the scan useful to the next decision-maker. At minimum, the project team should know what area was examined, what was marked or documented, what the operator could and could not interpret, and what must happen before intrusive work begins.
Ask the scanning contractor to clarify:
The building, floor, room, grid, or other location identifier.
The scan boundary and any areas that could not be accessed.
The planned cut, core, anchor, trench, or demolition location reviewed.
Detected features that may affect the planned work, including approximate location and depth when supported by the scan.
How field markings correspond to photos, sketches, or written notes.
Conditions that limited interpretation, such as moisture, congestion, finishes, or equipment.
Who reviewed the findings and which trade or facility representative received them.
Whether a changed design, moved penetration, or new work area requires another scan.
This is where a campus project benefits from a single accountable handoff. The person setting out a core or cut should not have to reconstruct the scan from an email thread or guess which markings belong to an earlier phase.
How can a Georgia campus prepare a quote request?
A strong quote request gives the scanning contractor enough detail to understand the work area, the decision deadline, the access conditions, and the desired deliverable. It should compare scope and accountability, not just a mobilization number.
Include these details in the request:
Facility name and Georgia project location.
Building, floor, room, grid, or drawing reference.
Approximate square footage or linear footage to scan.
Concrete type or surface description, if known.
Planned core, saw cut, anchor, demolition, or other intrusive task.
Requested field date and the date the next trade needs the decision.
Access, escort, parking, security, occupied-space, and work-hour requirements.
Available drawings, photos, utility records, and proposed work layout.
Required markings, photos, maps, sketches, or written documentation.
Facilities, engineering, safety, and trade contacts who should attend the review.
When the project also needs concrete cutting, core drilling, or demolition, an integrated provider may reduce handoff friction between the scan and the next operation. Compare the proposed scope carefully and confirm which party is responsible for interpretation, marking, execution, engineering coordination, and final approval.
Frequently asked questions
Is concrete scanning required for every campus project?
No single scanning decision fits every project. The owner, engineer, general contractor, and trade should evaluate the planned work, records, materials, access, and risk. Scanning is especially relevant when concrete will be penetrated or removed and embedded conditions could affect safety, structure, utilities, schedule, or building operations.
Can GPR confirm whether a campus utility is live?
Do not assume that a GPR scan establishes whether a utility is energized or active. Coordinate with the campus utility owner and follow the project's identification, shutdown, and verification procedures. Ask the scanning contractor to state what the scan can support and what remains outside its scope.
Does a concrete scan replace engineering review?
No. GPR findings can inform a work plan, but they do not replace structural design, engineering direction, utility coordination, permitting, or the facility's safety procedures. The project team should define who reviews the findings and who can authorize a change before intrusive work begins.
What if the planned core or saw cut moves after scanning?
Treat a moved penetration or cut as a new planning question. The team should compare the new location with the scan boundary and findings, then determine whether additional investigation is needed before proceeding.
