Case Studies

Bondi NSWResidential property, Observation deck slab

Problem – eleven blind core holes 90mm diameter by 75mm deep have been drilled into the 150mm thick concrete slab to accommodate the installation of LED lights. After drilling, Expensive stone tiles were laid onto the slab thus covering the core holes. The pencil markings to locate the core holes were lost and the holes could not be located.

Removing the tiles or re-drilling the holes were not an option as the conduit and wiring were already laid.

Solution – we were summoned to accurately locate the centers of the eleven core holes so that the tiles could be drilled and the LED lights installed.
Another job for the Mala CX-12 Concrete Scanner.

Outcome – we scanned the concrete slab and located the eleven voids under the tiles. By accurately marking the centers of the voids in either direction we were able to accurately mark the centers of each of the core holes.
This saved the builder considerable time and money and the job was back on schedule and on budget.

Our equipment is highly suited for locating voids within concrete structures, another happy customer.

Arndell Park NSWIndustrial property, Warehouse extension

Problem – Warehouse extension has been approved at this site. The proposed extension is to be erected on the grounds in front of the existing warehouse to cover an area of approximately 600 square meters. The existing warehouse structure had multiple services running into it across the large grassed area, which is to be excavated to build the new extension.

Solution – Sniper Concrete Scanning was summoned to scan the large grassed area to locate all services contained before any excavation works could commence. Footings of around two meters in depth were to be piled in this area.

A job for the Electromagnetic Scanner and the Mala HDR Ground Scanner.

Outcome – The Mala HDR ground scanner detected a clay crust of about 450mm deep from the top surface of the grassed area. Due to the amount of clay and moisture in this crust, the ground scanner was not suited for this job.

The Electromagnetic scanner was used to locate all the services that included mains, fire hydrant, telecommunications and gas services. These services were buried below the surface ranging from 200mm down to about 400mm deep.

Excavating this area without scanning would have been disastrous, as most of the services would have been struck leading to safety breaches, down time and huge repair bills.

By using multiple scanning technologies we were able to locate all of the buried services thus saving the contractor money and making a safer work environment. Another happy customer.

Rhodes NSWNew Chinese Restaurant

Problem – In excess of twenty core holes required in the suspended concrete slab as the building owner would not allow any chasing of the slab. The builders decided to core the slab without scanning it first which turned out to be disastrous. After the first core they hit the fire alarm system cables which were embedded in the slab.

Solution – Sniper Concrete Scanning was commisioned to scan the slab before further coring was to occur. The slab was successfully scanned and all critical services were identified thus resulting in the successful coring of all of the required core holes.

Outcome – success again… this proves how crucial it is to have any concrete structure scanned before any penetration.
