Lift shaft openings
Fourteen openings through a 350 mm RC core wall, cut over three night shifts with the building live.
Licensed contractor — est. YEARS
Diamond core drilling, wall and floor sawing, wire sawing and controlled demolition. Every cut is scanned before it is made, so nothing structural gets severed by accident.
Services
The right method depends on depth, access and what sits inside the concrete. We specify it after the scan, not before.

Clean round penetrations for MEP, anchoring and testing.
Ø25–600 mm→
Downward coring through suspended and ground floor slabs.
Ø25–600 mm→
Horizontal through-wall cores for AC, extract and services.
Ø25–600 mm→
Track-mounted sawing for doors, windows and lift shafts.
To 800 mm→
Slab sawing for trenches, joints and floor openings.
To 500 mm→
Diamond wire for mass concrete beyond blade reach.
No depth limit→
Structural RC cuts with propping and load transfer.
Engineer signed→
GPR survey and marked-up plan before any blade goes in.
To 600 mm→
Controlled demolition, slabs through to staircases.
Waste removed→
Suspended and ground slabs cut into sections and lifted out.
Propped & craned→
Flights and landings cut free and removed in sections.
Access sized→Scan before you cut
A slab is never just concrete. Reinforcement, post-tension cables and conduit all run through it, and a drawing from 2009 is not evidence of where they sit today.
We run GPR across the cut zone, mark findings on the surface, and issue a plan with depths noted. If the cut has to move, you find out in the survey, not mid-shutdown.

Hotels, malls and offices across Abu Dhabi and Dubai are cut at night, sheeted and handed back before the doors open.
Process
Mark openings on a PDF or DWG, or send a photo with dimensions. We reply within four working hours.
Free site visit. Access, power and slab condition checked, then the cut zone scanned.
Method, crew, duration and price. No hourly open ends, no variation on quoted scope.
Slurry contained, sections removed, waste taken off site, area handed back swept.
Sectors
What changes between sectors is not the cutting. It is the permits, the protection and the hours.
Riser penetrations and core wall openings on live floor plates.
Night shifts with full containment. Guests should not know we were there.
Dry cutting, class M extraction and strict noise windows.
Machine bases, plinths and trenches in Mussafah, Al Quoz and ICAD.
Openings, staircase removal and AC cores across Al Ain and Khalifa City.
Bridge sections, culverts and piers where wire sawing is the only option.
Plant
Segment specification is matched to the concrete. One blade for everything is why some contractors take three times as long on the same slab.

240 cores from Ø100 to Ø350 mm across nine floors, scanned and set out ahead of each pour.
Wire sawing and lift-out of a 90 m² section, propped, craned and cleared in six days.
Difference
Scanned as part of the job. Others quote it separately, then skip it when price gets tight.
Trained on diamond drilling and sawing, current UAE HSE cards. Ask and we send them.
Vacuum extraction and bunding on every cut. In occupied buildings, one complaint not forty.
Sections and debris removed within the quoted price, with transfer notes for your records.
Coverage
Crews based in CITY. Typical times from confirmed booking to boots on site.

Public liability to COVER, workmen's compensation. Certificates on request.
Method statements and risk assessments issued before mobilisation.
