CONSTRUCTION workers in Melbourne, Australia, have recently completed a day-long concrete raft pour, the largest of its kind in the city's history.
Covering an area of 1,000 square metres and located on top of an existing railway tunnel, the 3-metre deep raft foundation will support the core of Sapphire
by the Gardens, a residential and hotel development in central Melbourne.

The foundations also contain 450 tonnes of steel rebar and required 469 trucks and some 3,000 cubic metres of concrete to be brought onto the site in sequence.

Sapphire by the Gardens is a USD $381 million development consisting of two towers, of 57 and 59 storeys, linked by an expressive, gold-coloured skybridge.

The skybridge will contain a swimming pool and a two-storey sky-lobby.
The project, designed by Cox Architecture and Fender Katsalidis, is scheduled to complete by 2022.
