GSSI StructureScan Mini LT

TRSC carries the GSSI StructureScan Mini LT as a back-up to the Hilti PS 1000 and as the GPR instrument deployed by sub-contracted concrete-cutting partners on pre-cutting verification scans. The Mini LT has a smaller form factor than the PS 1000 (lighter, easier single-handed operation), which makes it advantageous in confined-space surveys (mechanical risers, tight cavity-wall access) and on overhead-soffit scans where the operator must hold the instrument above shoulder height for extended periods. The functional capability overlaps with the PS 1000 and Proceq instruments — the choice on a given investigation is driven by the existing instrument inventory of the cutting-contractor partner and the form-factor requirements of the access geometry. Operational discipline mirrors all hand-held GPR work: surface preparation to clean concrete, systematic survey grid (not random pass), and calibration verification against a known cover before relying on cover readings. The Mini LT is the standard recommendation TRSC makes to client cutting contractors for sites where TRSC itself is not on-site for the cutting operation but pre-cutting GPR verification is required to confirm the absence of post-tensioning tendons or services in the planned cut path. The instrument's integrated touchscreen also enables the cutting contractor to mark up scan results on-screen and capture screenshot evidence for the project file, supporting the documentation-of-due-diligence chain that TRSC's RPEQ engineer relies on when post-cutting Form 15 certification is requested for tenancy fitout or services penetration scopes, particularly on heritage and high-occupancy structures where the certification standard of care is materially elevated.
