Most compliance gaps are not missed tasks. They are tasks nobody was clearly assigned.
On a typical occupied building, statutory duties are split between landlord, tenant, managing agent and service provider. The gaps appear where that split was assumed rather than documented.
A simple matrix fixes most of it: each obligation listed once, with the duty holder, the delivering party, the frequency and where the record is filed. It takes an afternoon and removes the most common audit finding.
Applicable obligations depend on the building, its plant and its use. Ours are confirmed with the client following a site review rather than assumed from a template.
