A SIMMS audit is the standard full structural audit of mining structures in South Africa, run under a Structural Inspection and Maintenance Management programme. Delta Scan captures each structure with drones and 3D scanning, then a registered Pr Eng assigns condition categories and repair priorities in a signed report aligned to the mine's SIMM standard.
SIMM, short for Structural Inspection and Maintenance Management, grew out of Anglo American's technical standard for plant structures (AA TS 108 003, the SIMM Guideline for plant structures) and has been adopted across the South African mining industry as the common language for structural audits. It sits inside the duty-of-care framework of the Mine Health and Safety Act (Act 29 of 1996): every structure on a mine, from headgear and conveyor gantries to bins, silos, and plant steel, must be inspected, condition-rated, and maintained under a managed programme. A SIMMS audit assigns each structure a condition category and a level of priority, so safety-critical defects are surfaced, ranked, and tracked to close-out rather than buried in a report.
Delta Scan delivers SIMMS audits as a structural engineering service, not a checkbox exercise. Reality capture does the legwork: drones cover high steel and no-access areas, confined-space capture reaches bunkers and internal structures, and the resulting measurable 3D record means the condition assessment is grounded in complete coverage rather than what could be reached from a ladder. A registered Pr Eng reviews and signs the findings, and the full record lives in DeltaCloud where condition trends can be compared audit to audit.
