Two Assessments, One Word.
A tree risk assessment asks whether a tree is likely to fail and what it’d hit. It’s about the tree.
A job site risk assessment asks whether the planned work can be done safely, here, today, with these people and this equipment. It’s about the operation, and on an occupied commercial property it’s also about everybody who isn’t part of the crew.
What Gets Assessed Before Work Starts
| Factor | What It Changes |
|---|---|
| The tree and what’s in it | Dead limbs, hangers, decay at a working point, and anything the climber can’t rely on |
| What’s underneath and around | Drop zones, glazing, parked vehicles, pedestrian routes, and where debris will actually land |
| Overhead services | The constraint that stops a job entirely rather than complicating it |
| Ground conditions | Whether equipment can be positioned and whether the surface will carry it |
| People not in the crew | Tenants, deliveries, contractors and the public, who won’t be watching for you |
| Weather on the day | Wind especially, which stops aerial work regardless of what was scheduled |
What A Property Manager Should See
Three things, and their absence is the signal.
A Walk Before The Work

Somebody looking at the site and the tree before equipment comes off the truck. A crew that arrives and starts has either assessed it previously or isn’t assessing it.
A Drop Zone Nobody Can Walk Into

Cones and tape are the visible part. The real question is whether somebody is watching the boundary, because on an occupied site people walk through anything unattended.
A Willingness To Stop

Wind rising, a vehicle nobody can move, a service nobody can identify. A crew that finishes regardless of what changed is the risk you were trying to manage.
Why This Is Your Concern, Not Just Ours.
The work happens on your property, around your tenants, and if something goes wrong it happens to your site.
That makes the contractor’s own safety practice a property risk rather than an internal matter. It’s a fair question to ask before appointing anybody, and the answer tells you more about how a job will go than the price does.
The Constraint That Stops Work
Overhead electrical services, which is the one item on this page that isn’t a matter of care and attention.
Work near energized lines is specialist work with clearance requirements, and the correct response to finding an unexpected line is to stop and resolve it rather than to work carefully around it. A crew that treats a service drop as an inconvenience is telling you what its other judgments look like.
Wind Is The Common Cancellation
Aerial work becomes unsafe well before conditions look dramatic from the ground. A climber high in a crown experiences movement that isn’t obvious from a parking lot, and a rigged section behaves unpredictably in gusts.
A crew that postpones is exercising judgment rather than failing to deliver, and a property that treats a postponement as a service failure creates pressure toward the wrong decision. It’s worth agreeing in advance that weather calls are the crew’s to make.
What Should Be Written Down
Very little, and the little matters.
Which trees were worked on, what was found on the day that changed the plan, anything postponed and why, and the condition of anything preserved when the crew left. That’s four lines, and it’s the record that answers a question three months later about whether the damage somebody noticed was there before the work.
A crew that leaves no note has left you relying on memory, which is the weakest evidence available and the only kind most properties have.
The Part That Gets Skipped
Not the assessment itself, which most competent crews do. The part that gets skipped is telling anyone.
A drop zone marked with cones that nobody explained, work starting without the site manager knowing, or a lane closed twenty minutes before a delivery arrives. Each of those is an assessment that was carried out and then kept internal, and each produces the confrontation that makes tenants complain.
The communication is part of the control, not a courtesy on top of it. A crew that has assessed the site properly and told nobody has managed its own risk and transferred yours.
What Changes On An Occupied Property
Everything about the surroundings, and nothing about the tree.
The same removal on an empty lot and beside a trading retail unit is the same arboriculture and a different job. Timing, access, the size of the exclusion zone, how debris leaves and who is watching the boundary all change, which is why the assessment happens on the day and in the place rather than being carried over from a similar job last week.
