Stair and lift voids
New voids through suspended slabs for stairs, lifts and escalators in occupied commercial buildings.
Cut-outs in occupied buildings
Selective & precision demolition
New stair voids, lift shafts, atriums, service penetrations and structural modifications in buildings that are still in use. Low vibration, dust captured at source, and a machine that’s gone by the time the tenants arrive.
Selective & precisionQuote this job
Remove exactly what the engineer marked
Selective demolition is about restraint. A new stair void through a suspended slab, a lift shaft cut through three floors, an opening in a shear wall for a link bridge: each one is a structural modification where taking out too much, or shaking the structure too hard, is a serious problem.
A demolition robot gives the operator control that a jackhammer crew doesn’t have. The breaker or crusher works to a marked line, reinforcement is exposed and cut deliberately rather than torn, and vibration to the surrounding structure is a fraction of what an excavator hammer would impart. In hospitals, data centres, schools and retail buildings that difference is the difference between the job going ahead and not.

Applications
Typical selective demolition jobs
Every job is different, but these are the ones we’re called in for most.
Atrium and link openings
Large slab openings and wall penetrations for atriums, link bridges and interconnecting floors.
Service penetrations
Openings through slabs and walls for mechanical, electrical and hydraulic services in live buildings.
Strengthening prep
Concrete removal around columns, beams and connections ahead of steel or carbon-fibre strengthening.
Heritage structure works
Careful removal of later additions from heritage-listed concrete and masonry structures.
Facade and balcony repairs
Spalled concrete removal on balconies, facades and awnings with the operator behind the edge.
How it goes
From drawings to handover
Priced before we mobilise, planned before we break, cleaned up before we leave.
01
Scope & quote
Send drawings or photos. We confirm access, structure, services and the right machine, and give you a price.
02
Plan & SWMS
Site walk, engineering check where needed, SWMS, exclusion zones, dust and noise plan, waste route.
03
Mobilise & break
Robot arrives on a small truck, walks in under its own power, and gets to work with the operator at a safe distance.
04
Clear & hand over
Debris crushed and removed, dust suppressed, area cleaned and handed back on program.
FAQ
Selective & precision: common questions
How accurate is robotic selective demolition?
The operator works to the engineer’s marked line and can remove concrete in small, deliberate bites. Where a clean edge is needed we combine robotic breaking with saw-cutting: cut the line, then break out the panel behind it.
What about vibration to the rest of the building?
Robotic breaking with a light, controlled breaker or a crusher imparts far less vibration than an excavator-mounted hammer. On sensitive sites we can monitor vibration and adjust the attachment or sequence to stay within the limit.
Can you work outside business hours?
Yes. In occupied buildings we often work nights and weekends, and the machine can be tracked out of the space at the end of each shift so the area is clean and clear for the building’s users.
Do you need the structure propped?
That’s the engineer’s call, and we work to their temporary works design. The robot’s small footprint and controlled removal often reduce the extent of propping needed compared with heavier methods.
