443 Queen Street is a whole building rather than a single job. We clean the glass, wash the facade, maintain the vertical gardens and certify the roof anchor system, all off the same roof and the same ropes. The gardens are the part people notice from Queen Street, and they are the awkward part, so start there.

The planting is built into the facade rather than sitting in a garden bed at the bottom. Planters are set into the building every few levels, all the way down, so the greenery is a good part of what the tower looks like from the street. That makes it a maintenance problem with two halves: it has to be pruned like a garden, and it has to be reached like a facade. A landscaper can hedge back a cissus, but not from a rope thirty storeys up. A rope crew can get to it, but will not know what to cut or what it will do next season. Our technicians hold horticulture and arborist tickets alongside their IRATA certification, so the same people who rig the drop are the ones deciding what comes off.

The gardens

Garden management on a facade

A vertical garden fails quietly. The cissus and jasmine get away over a season, growth creeps across the glass, vines start wrapping the trees on the landings, and the first anyone says about it is that the building looks untidy from Queen Street.

On every round

Hedge back the cissus and jasmine on every planter level, and anything growing across the glass

Cut the vines off the trees on the intermediate landings before they take them over

Clear leaf litter and debris off the landings and out of the planters

Bag green waste on the rope rather than dropping it, and take every bag off site at the end

Flag what a trim will not fix, whether that is drainage, dead stock or pests

How a round runs

Rounds land roughly quarterly, most recently in November, February, May and August. Each one is about two days with three to five technicians, starting at 7am. The riverside elevation goes first, then the northern Queen Street drop, then the southern side. Where a drop cannot be finished in a day the ropes are tied off and picked up the next morning.

A progress report goes to the building manager at the end of every day: who was on site, what was actually cut, what is planned for tomorrow. Photos go up to a live gallery the same day, so nobody has to take our word for what happened thirty storeys up.

Glass and facade

Cleaning the building the garden sits on

The same roof anchors and the same crew that maintain the planting clean the glass and wash the facade. The tower gets a full external window clean on an annual cycle, and the GRC panels and rendered surfaces are washed off the same access rather than a separate mobilisation.

On a window clean

All external inaccessible glass from parapet to podium, finished with pure water so it dries clear

The external side of the balcony balustrade glass on every apartment

Frames, sills and spandrel panels wiped down with the glass, not just the pane

Drops planned elevation by elevation, with a resident notice out before we start

Residents SMSed the day before their drop, so balconies are clear when we pass

Resident balconies

Anything inside a resident balcony is theirs, so we leave it alone unless they ask us in. Residents who want their own balcony glass done book and pay for it themselves, while the crew is already on the ropes outside their apartment.

The building manager administers none of it. No list to keep, no money to collect, no scheduling to do. It is arranged between us and the resident, and it happens on a drop that was going past anyway.

Height safety

The anchors that make all of it possible

Every drop on this building hangs off the roof anchor system, so it has to be in certification before anyone goes over the edge. We inspect, load test and certify it each year.

What the inspection covers

Every anchor, static line and davit socket on the roof, inspected and load tested to AS/NZS 1891.4

A certificate and an asset register listing what passed, what failed and where each asset sits

Anything that fails tagged out on the spot, so nobody can use it

Rectification quoted separately, and the building free to have anyone do it

Done while we are already here

The inspection runs on the first morning of a clean, while the crew is rigging anyway. That is the cheapest time to have someone competent on the roof, and it means the certificate is renewed before it lapses rather than after somebody notices.

It also means the people who certify the system are the people who use it. Nobody signs off an anchor they would not hang off themselves.

How we get to it

Rigged from the roof

Almost all of this job is rigged from the roof. Keys signed out from management, materials carried up, then down the elevation on rope. It keeps the work off the footpath and out of the way of everyone using the building.

Getting to the planters

Planters set into the facade every few levels mean a technician has to stop partway down and work, not just pass through. Drops are rigged as retrieval systems so the crew can hold position at each planter level, hedge it back, bag what comes off and keep moving.

Materials live in the roof plant room for the duration, stored neatly and out of the way. Roof access doors are closed and secured behind the crew every time.

How we leave it

Tools tethered, and green waste bagged on the rope rather than dropped

Bags stored discreetly on site during the round and taken off site at the end of it

Keys and passes back to management before anyone leaves

Equipment, bollards and signage packed away in a spot management has approved

Every access door locked and the building manager spoken to before the crew vacates

Photos uploaded the same day, so the record exists whether or not anyone asks for it

Challenges

What makes this one awkward

None of it is difficult on its own. It is awkward because several things have to be true at the same time.

The planters sit between levels rather than at them, so a technician cannot stop at a floor and reach out. Each drop is planned around where the boxes actually are, and a retrieval rope goes in so someone can hold position between landings.

Everything below is glass and footpath, so nothing comes off the building. Green waste is bagged on the rope and carried down. And it is a working tower on Queen Street, so drops run elevation by elevation, and where one cannot be finished in a day the ropes are tied off and picked up the next morning.

Outcome

What the building gets

The planting stays looking deliberate rather than overgrown, which matters more here than it would on a plain facade, because at 443 Queen Street the garden is a good part of the building's face. The glass and the facade stay on a cycle rather than getting done when somebody complains. There is no season where a section sits visibly out of control while someone chases a quote.

Rigging a tower is most of the cost of working on it, so doing the gardens, the glass, the facade and the anchor inspection with one contractor off one set of ropes costs the building less than four contractors rigging four times. One crew who know the building, one point of contact, one set of reports. The quieter benefit is the paper trail: every visit leaves a daily report and a dated photo gallery covering parts of the building nobody can see from the ground. When the committee asks what has been done up there, the answer is already written down.
