Selective demolition
One wall, one bay, one floor slab opening. Removed exactly, with everything around it still standing and still finished.
When people call us about selective demolition
- A layout change needs one wall out and the rest of the finishes protected
- A new stair or lift needs an opening cut through a slab
- A tenant space is being reconfigured while neighbouring units trade
- An engineer has specified partial removal ahead of strengthening work
What selective demolition covers
- Individual partitions and masonry walls
- Slab and floor openings, cut rather than broken where the surround has to stay
- Partial ceiling and bulkhead removal
- Removal of specific structural elements under an engineer’s direction, with temporary support in place
- Making good the cut edges so the following trade has a clean line
The support goes in before the element comes out
Anything carrying load gets propped or needled before it is touched, to a scheme that has been designed rather than judged on the day. That is the whole discipline of selective work. If a wall turns out to be doing more than the drawings say, we stop and get it looked at rather than carrying on and finding out later.
How selective demolition runs
The same order every time, whatever the scale.
We walk the site
We look at what is coming out, what is staying, and how we get to it. Access decides most of the plan in this city: a fourth-floor walk-up and a loading dock are two different jobs even when the scope is identical.
We tell you which filing you need
Full structure, interior gut, or work small enough to sit outside a filing. You get a straight answer on which path applies and what it needs before we quote, not after you have committed.
Asbestos gets settled first
Anything built before April 1987 needs an asbestos assessment before a permit is issued. We arrange the investigator and the ACP-5 filing. This is the step that most often moves a start date, so we start it early.
We protect, then we start
Floors, stairs, lift lobbies and anything staying get covered before a tool comes out. Utilities are proved dead. Then the work runs in a set order, with the route material takes out of the building settled before any of it moves.
You get the site back clean
Loads leave covered, to a permitted transfer station, with documentation for each one. We sweep out and hand over a space the next trade can start in.
What moves the price on selective demolition
Every one of these moves the number, so you can see what a quote is actually responding to — and tell us the ones you already know when you call.
- Whether the element is load bearing, and what temporary support it needs
- Cut method, since sawing to a clean line costs more than breaking out
- How much protection the surrounding finishes need
- Working hours, if the building is occupied
- Whether the work sits inside an existing filing or needs its own
Selective demolition: your questions
How do you know if a wall is load bearing?
We look at direction of span, what is above it, and how it is built, and where there is any doubt the answer comes from a structural engineer rather than from us. We would rather delay a day than remove something that was holding a floor up.
Can you cut an opening without cracking the ceiling below?
Cut, yes, rather than break. Saw cutting to a marked line is slower and more expensive than breaking out, and it is the reason the room below still has a ceiling afterwards.
Can this run while the offices next door are working?
Usually, with agreed hours, sealed separation and the noisy operations blocked into windows everyone knows about in advance.
