About the project:

In light of the ever-growing concern for commercial buildings across Australia containing combustible cladding, the building for TAFE NSW in Ultimo had scheduled the replacement for the non-compliant ACP on the eaves of Blocks E & F, with a goal to minimise disruption to students and teachers due to work being conducted during business hours and whilst classes were being held. In addition, The Apprentice Restaurant which is a student run and student cooked fine dining restaurant located on the top floor of the TAFE remained operational and continued to serve the public.

Scope of the project:

ARA Building Services provided all the labour, materials, plant and equipment necessary to remove the existing non-compliant combustible eaves in Blocks E & F at TAFE NSW Ultimo and replace with a non-combustible aluminum panel Vitracore G2 which complies with the National Construction Code. The project was undertaken in 5 stages over a 17 week period. A combination of access was required due to the lie of the land and construction of the TAFE. The eaves were approximately 25M above ground.

Challenges of the project:

1. As Ultimo TAFE NSW was operational, ARA Building Services needed to make allowance for student / teacher pedestrian car access and daily goods deliveries.

2. All works were accessed via a Boom lift, however, in stage 2 as the driveway gradient was too steep, the ARA Building Team changed its process to a Knuckle boom where the team required to remove and install the existing non-compliant panels, consisted of 2 x men in the Knuckle boom and 2 x abseilers over the driveway entrance, which had to be completed on a night-shift.

3. During Stage 4, the elevation had a curtain wall, comprised of fixed panes and windows, making it difficult to tie in scaffolding. Utilising the Knuckle boom the team were able to investigate but the street gradient would’ve made the job difficult therefore the ARA Building Services team designed and constructed an aluminium cantilever system internally anchored on the roof to access Thomas Street.

4. As Harris Street has a public footpath with high pedestrian traffic flow, it was imperative that Class B hoardings provided access for loading dock, and for the main entrance, it was important the steel scaffolding tied into the slab edges was used for that stage.
