Why the administration of a dwelling takes so much
A project with forty dwellings has the same set of documents forty times, but each time with different content. The EPC of plot 12 is not that of plot 13. The inspection report of the electrical installation, the sewerage certificate, the post-intervention file: one per dwelling, drawn up by a different inspector or engineering firm.
These documents are needed at set moments: the EPC to put the dwelling up for sale, the inspection report at handover, the cadastral data for the deed at the notary. Whoever only finds out on the day of the deed that a certificate is missing has to move the appointment with the buyer.
With IRP in Lean ERP you record this administration as the steps of a process, with per step the documents that belong to it, at dwelling level. Below is an example of such a step plan. You can model your own processes in IRP.
