Approximately 200 units of two different configurations were required, all with a high grade off form finish visible from the platforms. Accordingly, the quality of the moulds were of paramount importance & in Bianco’s design, no expense was spared to achieve the desired result.
The moulds were complex & deterred many Precasters from contemplating tendering. Many components were computer cut to size & joined by welding, with all welds ground flush with the finished surface. The visible off form surface therefore presented excellent sharp arrases & being suitably tapered, only the exterior formwork needed stripping.
The mould cost, although high, was justified as it amortised at less than $500 per unit or $25 per M2, allowed a daily cycle & provided a quality finish with labour savings of approximately 20% during manufacture.
