In the biggest expansion since it first opened in 1985, Perth’s Burswood international resort casino is completing a $68m redevelopment in time for the holiday season. The upgrade will provide the resort complex with new facilities including a food emporium, cabaret nightclub and grand ballroom.

The continued use of Lysaght Bondek steel decking from BHP Building Products as permanent formwork in the redevelopment maintains the casino’s employment of the material, which began with the construction of the original complex.

Arup principal Adrian Roberts who has been involved with the project from its outset, says Bondek steel decking has been varied in its application at Burswood due to differing architectural design requirements.

“The original intention in specifying Bondek steel decking as permanent formwork was to take advantage of the economy and speed of the system,” says Roberts. “Over the years there has been a substantial amount of Bondek steel decking installed on site in extensions to the complex.

“Unlike a conventional multi-storey building however, where all the floors from the first to the fiftieth are identical, at Burswood there are many voids and cantilevered floor edges which introduce a higher level of complexity. Bondek steel permanent formwork has still allowed us to engineer economical composite beams in the complex.”

Roberts says the use of the Bondek steel floor option had also generally proved to be more buildable and cheaper.

Since the construction of the original casino the introduction of fire engineering design has also delivered cost efficiencies associated with the Bondek system. Whereas the steelwork was originally sprayed to meet requirements for the fire rating, studies on additions have shown that unprotected steelwork provides sufficient fire resistance to meet BCA performance requirements.
