Built for BSA 2022 · Accountable Person & BSM
Accountable Person software for occupied HRBs
BSR registration, safety case, 16 KBI categories, occurrences, Building Assessment Certificate workflows, Part 5 remediation, and resident engagement — with Gateway 1, Gateway 2, and Gateway 3 design records and golden thread in the same platform.
