Audit before tender
The audit is straightforward but rarely done. For each existing arrangement, record what it covers, how often, what it costs annually, who instructs it and when it can be terminated. Then walk the site and mark every area against that list. The areas nobody has claimed are the gaps, and the areas claimed twice are the overlaps. Both cost money, and both are invisible while the arrangements sit in separate files with different renewal dates.
Gaps are usually in transitional spaces: the corridor between two tenancies, the rear service area, the external entry, the storeroom. Overlaps are usually in high-visibility areas that more than one supplier considered part of their remit. Once mapped, the consolidated scope can be written to cover everything once, which is normally where the saving in a consolidation exercise actually comes from rather than from a lower hourly rate.
