Vero Building, Auckland City
Sansom Construction Systems in conjunction with Blue Clean were contracted by the Kiwi Property Group to complete maintenance work on the ‘Halo’ that sits on top of the Vero Centre in the Auckland CBD.
At 175 meters (574 ft) it is the tallest building (with continuous occupiable floors) in Auckland.
Project Requirements
This project came about as a routine maintenance item for the ‘Halo’. The existing sealant joints between the aluminum panels had met their service life and needed to be replaced. Once the existing sealant was removed, new PEF backing rod was installed, Sika Primer-3 N painted on the edges and Sikaflex AT-Facade applied to the joints.
Challenges
- Access - “Take a lift to floor 39, walk up 3 flights of stairs, then climb a 6 metre ladder..."
- Weather - Too dangerous to work if there was any moisture on the surface, even a coating of dew. “Any moisture on a steep sloping aluminum substrate can be like dish-washing liquid on vinyl"
- The steep slope of the Halo - "Not quite abseiling but very close”. Applicators had to wear tethered safety harnesses"
- Other safety considerations - "No drop protection on the Halo so all tools had to be bagged and product could only be brought up in small amounts"
Sika Solution
“We’ve done a lot of work with Sikaflex AT-Facade so from previous experience we knew it would do the job - it was a no-brainer”.
