The cost of post-tension slab X-ray inspection is driven by slab size, access, and the required level of detail. Typical factors include the number of tendons, the length of the run to be scanned, equipment used, and whether a full enclosure or access ports are needed. Cost estimates generally combine scanning labor, equipment time, and reporting.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Test Type | $1,400 | $2,350 | $3,800 | Basic single-slab scan to verify tendon layout. |
| Labor & Inspection Time | $600 | $1,400 | $2,100 | Includes technician time on-site. |
| Equipment Usage | $400 | $1,000 | $1,700 | GPR/EM methods and calibration. |
| Reporting & Documentation | $150 | $350 | $750 | Formal findings and stamped summary. |
| Permits & Access | $50 | $150 | $480 | Local permissions if required. |
Assumptions: region, slab thickness, tendon count, access to the slab, and required reporting level.
Overview Of Costs
Cost ranges reflect typical commercial and residential projects in the United States. The total project range for a standard post-tension slab X-ray inspection generally falls between $2,000 and $6,000, depending on slab size, complexity, and access. Per-unit estimates commonly appear as $2.50-$6.50 per assessable tendon length or $0.50-$1.25 per square foot of slab area, when integrated into broader construction oversight. Assumptions: single-location survey, standard concrete mix, and no extensive repairs required.
Cost Breakdown
The following table aggregates common cost components to show where money goes. The values below are indicative and assume a typical residential or light commercial slab with moderate tendon density. Higher penalties occur with restricted access or long tendon runs.
| Materials | Labor | Equipment | Permits | Delivery/Disposal | Warranty | Overhead | Contingency |
|---|---|---|---|---|---|---|---|
| $0-$200 | $600-$1,400 | $400-$1,000 | $50-$480 | $0-$120 | $50-$150 | $100-$300 | $200-$600 |
What Drives Price
Key pricing variables include slab area, tendon density, and the number of runs to scan. Labor hours and hourly rates vary by region and the technician’s experience. A mid-range project, with average tendon length and moderate access, typically incurs higher labor and equipment use costs due to calibration and data processing time. data-formula=”labor_hours × hourly_rate”>
Ways To Save
Strategies to reduce cost focus on planning, scope clarity, and efficient scheduling. Booking a single crew for both scanning and reporting can lower overhead. Ensure access paths are prepared to minimize on-site time. Compare quotes for similar scanning methods to avoid overpaying for advanced techniques unnecessary for the project scope.
Regional Price Differences
Prices can shift by region due to labor costs, permitting processes, and local demand. In the Northeast, expect higher labor rates and potentially more rigorous reporting requirements. The Midwest often offers mid-range rates with faster on-site turnover. The Southwest may present lower overall costs but higher travel-related fees if the worksite is remote. Regional deltas typically range from -10% to +25% relative to national averages, depending on the project specifics.
Labor, Hours & Rates
On-site time is a major driver. A typical crew may consist of two technicians working 6–12 hours for a standard slab, with rates ranging from $85 to $180 per hour per technician depending on specialty certification and local wage levels. Estimate criteria include tendon count, slab thickness, and access conditions.

Three scenario cards illustrate common outcomes. Each card lists specs, labor hours, per-unit prices, and totals. Assumptions: standard concrete, modest access, and a formal report delivered after testing.
| Scenario | Specs | Labor Hours | Rate | Per-Unit | Total |
|---|---|---|---|---|---|
| Basic | Single slab, low tendon density, open access | 4-6 | $100/hr | $2,000-$2,400 | $2,400-$2,800 |
| Mid-Range | Two slabs, moderate tendon density, partial enclosure | 8-12 | $120/hr | $3,000-$4,500 | $4,300-$6,200 |
| Premium | Three slabs, high tendon density, full access, detailed report | 12-20 | $150/hr | $5,000-$7,500 | $7,500-$10,500 |
