Quality Level B and A deliverables for design teams.
Subsurface Utility Engineering (SUE) per ASCE 38 defines four quality levels of subsurface information. Quality Level B (designating with surface geophysics) and Quality Level A (locating with controlled potholing) are the workhorses of design-phase utility verification. We deliver Quality Level B/A subsurface utility engineering for design teams, with deliverables structured to industry standards and integrated into engineering submissions.
Utility Scan is a sub-division of Leak.ca, the Greater Vancouver leak detection company trusted since 1999. Every site visit is delivered by certified technicians using calibrated equipment, with documented findings formatted for insurance, engineering and procurement use.
We don't sell remediation. Our role is independent detection and assessment — the data you and your professional team work from.
Yes — Quality Levels B and A standard; we coordinate Quality Level A potholing with appropriate contractors.
Standard — DWG/DXF with georeferencing.
