Case I

Examining the reports that followed 420 closed requests

In 2023 I asked for a defined review of non-urgent comfort requests across twelve Marlivane buildings. The operating account showed 420 requests closed. That figure described recorded actions, but occupier conversations suggested that some experiences had continued. I wanted to examine those later reports without retrospectively assuming every closure was wrong or every complaint described the same technical problem.

The review identified eighty-three subsequent reports from the same locations within thirty days. Qualified assessment and the available account supported fifty-two as the same problem. Thirty-one were different concerns or remained insufficiently established. We kept that distinction explicit. A shared location was a reason to investigate; it was not by itself a diagnosis. The population was a selected group of non-urgent requests, not a measure of all faults, safety conditions or repair quality across the portfolio.

I authorised A$310,000 for investigation and coordination within the operating programme. A colleague argued that reopening the discussion would make a completed-work report appear unreliable. I thought a report became less reliable when it could not accommodate the next relevant observation. We preserved the original 420 closures and placed the recurrence account beside them, rather than changing the first number to manufacture a cleaner comparison.

The technical teams considered the supported cases and the questions still open. I did not prescribe a repair method or announce that every recurring concern had been permanently removed. My decision was to fund the examination and make its findings part of the asset conversation. That required more time and expense than accepting the closure count as the last word.

The immediate consequence was a more qualified account of completion. Management could distinguish work recorded as done, subsequent contact, a supported recurrence and an unresolved diagnosis. I would bring that distinction into the review design earlier now, so that the first report already explains what later evidence might change our understanding. The point was not to discredit the colleagues who closed a request; it was to keep learning about the building after an administrative milestone.

Case II

Separating a routine booking from a visit that could take place

A 2016 review examined ninety-six planned routine access visits in the property portfolio. Sixty-eight had been performed and twenty-eight had not. Of the unperformed group, eighteen lacked confirmed occupier arrangements and ten conflicted with contractor availability. The original schedule had brought these conditions together too late, so a booking could appear ready while one of the participants still could not support it.

I worked with property managers, occupier contacts and the contractor coordinators to distinguish the date requested from the date on which the visit could credibly occur. One programme colleague wanted to retain the original appointment count because changing it would expose how little of the schedule was secure. I preferred that exposure before another unsuccessful visit. The plan needed to describe access arrangements and contractor availability separately, along with the building controls applicable to the work.

We incurred A$84,000 in additional coordination and repeat-visit expense. I did not hide that amount inside the next routine budget or attribute it entirely to occupiers. Our own scheduling account had implied more readiness than it established. Some visits required a different time; others needed a conversation about the work and the appropriate person to confirm arrangements.

A later, distinct cohort of ninety-six planned visits recorded eighty-four performed and twelve unperformed. That was useful follow-up, but the buildings, tasks and circumstances were not a controlled experiment. I did not claim that the coordination change alone caused the difference or that all access problems had ended. Each remaining failure still needed its own explanation.

The decision concerned routine planned activity. It did not authorise delaying urgent work, bypassing an occupier’s rights or dispensing with safety requirements. Those matters retained their proper decision paths. My operating lesson was narrower and more useful: a scheduled visit should carry a credible account of the conditions that let it happen, and a failed visit should remain visible until we understand which condition was missing.

Case III

Funding the evening service implied by a different tenant day

In 2018 several occupiers in four buildings changed the pattern of their working day. Our established arrangements supported selected weekday services until 18:00, while more people were using the buildings later. The property could be described as accessible without every supporting service having the same hours. I wanted the operating proposition to make those differences clear before a general statement of availability became an unexamined promise.

We examined which services were actually required, how people entered and left, and which responsibilities belonged with the occupier rather than the landlord. The relevant property, staffing and technical colleagues assessed their own parts of the arrangement. I did not assume that extending one service automatically established every condition needed for evening use, or that all four buildings required identical treatment.

The agreed programme extended selected weekday services from 18:00 to 21:00 and added A$240,000 in annual operating expense. A commercial colleague argued that the longer day should be absorbed within the existing service account because the tenants already had access. I disagreed with treating access and the full supporting operation as interchangeable. The additional work needed an explicit owner and an honest funding decision.

The expense remained visible in the portfolio plan. It was not presented as proof of higher rent, certain retention or a financial return from the longer hours. The arrangement also stopped short of a general twenty-four-hour proposition. Each building’s agreed scope and applicable requirements continued to govern what was offered.

This decision gave the operating team a clearer service account and occupier contacts a more specific explanation. It also made the limits easier to discuss. A tenant’s changing day is commercially important, but the response has to identify the work that will support it. I would now bring the operating discussion into the earlier conversation about proposed use, while keeping specialist assessment and contractual interpretation with the people responsible for them.

Case IV

Restoring communal cleaning after my vacancy assumption proved incomplete

In 2008 vacant area across four buildings rose from twelve to twenty-eight per cent. As regional building operations manager, I supported reducing the annual routine cleaning scope by A$90,000 from an A$360,000 account. My recommendation relied too heavily on the change in occupied area. It did not examine enough of the activity that continued through entrances, lifts and shared facilities.

A property colleague challenged the reduction, explaining that the remaining occupiers still used much of the same common space. I initially gave too much weight to the portfolio percentage and too little to that account. The result was a service scope that did not match the pattern of use we subsequently observed. I had translated less occupied area into less work without showing where the work had actually disappeared.

We reviewed the communal tasks with the responsible teams and restored part of the service. The correction incurred A$72,000 in additional expense over the following six months. That amount and the earlier annual reduction refer to different periods and scopes; subtracting one from the other would not establish an annual saving. I kept both in the explanation of the decision instead of presenting the restoration as an unrelated new requirement.

The revision did not reinstate every previous task automatically. It distinguished work attached to vacant areas from continuing common-area needs, within the relevant contracts and employment arrangements. Technical or hygiene requirements were not mine to waive for a budget goal. I also had to explain the correction to colleagues who had accepted my original recommendation and expected its cost effect to continue.

The error changed the evidence I require before recommending a scope reduction. I now ask teams to describe the actual use and task, rather than make an area ratio do the whole argument. A senior operating record should include the decision that became more expensive because the initial reasoning was incomplete. Keeping it visible is more useful than turning the eventual revision into a story of uninterrupted foresight.

Case V

Taking twelve equipment groups through condition review before choosing their next course

In 2025 repeated operating attention to ageing equipment raised a capital question. I wanted the investment discussion to begin with a qualified assessment of the actual groups involved, rather than a rule that everything beyond a particular age should be replaced. We commissioned an independent condition review covering twelve equipment groups at a cost of A$180,000.

The review led to eight groups receiving reviewed maintenance plans and four entering capital proposals. Those categories described different courses of action, not a declaration that eight groups were permanently free from concern. The maintenance plans retained responsible owners and review points. The capital proposals still required assessment of delivery, occupier effects and the appropriate approval.

A finance colleague preferred one portfolio-wide timetable, arguing that a single programme would be simpler to fund and explain. I supported a differentiated account because the condition evidence did not support treating the twelve groups as identical. That choice required more detailed planning and preserved the cost of the review. Simplicity in the funding presentation was not sufficient reason to disregard the underlying differences.

A separate A$920,000 replacement programme was authorised for the four groups taken into capital planning. I coordinated the operating implications and management recommendation; the capital authority and technical findings were distinct from my expense delegation. Neither the review cost nor the replacement allocation was presented as a measured energy saving or an assurance against future failure.

The consequence was an asset discussion with a clearer basis for the different decisions. We could explain why some work remained maintenance and why other work entered a funded replacement programme. The record also retained what had not been established. I would repeat the disciplined use of condition evidence, while avoiding the claim that this particular division supplied a universal rule for every ageing building system. The useful operating contribution was the connection between observed experience, specialist examination and the institution’s next authorised commitment.
