Ferroscan Survey
Electromagnetic rebar mapping — location, spacing, cover and diameter — charted onto your own CAD backgrounds.
Discipline 07 · Diagnostics & NDT
Testing & Technical Assessment.
Data-backed ground truth — accredited non-destructive testing and field inspection that replace assumption with verified numbers, so a structure is neither over-designed nor left carrying a hazard nobody has looked for.

01 Scope
Scope of work
What we deliver
Accredited NDT and field testing that replace assumption with verified ground truth: concrete strength, rebar layout, carbonation depth and soil bearing capacity — protecting clients from over-design on one side and from unaddressed structural hazards on the other.
- Schmidt rebound hammer (ASTM C805): in-situ surface hardness, uniformity mapping and strength correlation
- Ultrasonic pulse velocity (ASTM C597): acoustic testing for internal voids, cracks and honeycombing
- Core extraction and crushing: diamond coring located to miss reinforcement, laboratory compression per ASTM C42
- Ferroscan rebar detection: electromagnetic mapping of bar location, spacing, diameter and concrete cover
- Carbonation and chloride testing: phenolphthalein depth measurement to establish degradation and cover adequacy
- Soil investigation and bearing capacity reports with SPT, sampling and geotechnical coordination
- Existing-structure assessment under ACI 364.1R: capacity review, repair recommendations and load-rating advice
02 DeliverablesIncluded
Every package includes
Clear deliverables, fixed scope, milestone billing.
Core & Lab Testing
Diamond cores located to miss reinforcement, crushed in accredited laboratories and mapped back to grid positions.
Evidence Dossier
Rebound, UPV, core, carbonation and soil results georeferenced and audit-ready for insurers, lenders and authorities.

03 ProcessHow we work
How an MTech project runs
From agreed design basis to senior peer vetting and signed submission — the same five-step rhythm on every engagement, so you always know what happens next.
Consultation
We agree what the assessment has to prove — whether that is a capacity review, a defect investigation, an insurance condition or a pre-purchase check.
Survey & Analysis
A walkover and drawing review set the test plan: which members, what methods, how many points, and how the locations will be marked so they can be found again.
Testing & Review
Calibrated equipment, cited methods and controlled sampling — rebound, UPV, ferroscan, cores, carbonation — with results read back against the design intent.
Reporting
One dossier: results by grid position, statistical interpretation, correlation to design strength and clear conclusions a structural reviewer can defend.
Follow-on Support
Repair specifications, capacity or load-rating advice, monitoring schedules and re-testing after remedial work.
04 Design basisStandards
Codes and standards we work to.
Every test follows a cited method and a calibrated instrument, so the numbers hold up in a structural review, an insurance claim or a court.
