High Rise Units
EDGEWORTH DAVID ROAD, WAITARA

This project is located adjacent to Edgeworth David Avenue between Waitara Avenue and Orara Street and is one of many unit developments forming part of the high rise precinct located between Hornsby Westfield’s Shopping Centre and Waitara Railway Station.

The 84 unit development consists of 2 seven storey towers both located over a common 2 level basement carpark.

The main structure is based on a conventionally reinforced concrete frame with transfer slabs at both level 4 and ground level. The basement perimeter retaining walls have been constructed in reinforced concrete masonry.

The bulk excavation was predominantly in stable rock and accordingly only a relatively small portion of the excavation required temporary shoring.

Internal partitions consist of plasterboard mounted on either metal stud frames or “Hebel Powerpanels”. This system was favoured by the client due to the speed of erection and uniform internal finish compared to that of cement rendering.

Conventional face brickwork seen in the exterior is tied to a metal stud frame which is secured to the concrete floor slabs.

The pitched tiled roof of the penthouses is supported by prefabricated timber trusses which were not able to be supported by “Hebel” panels. A completely free standing structural steel frame had to be designed to carry roof trusses independently of wall partitions.
