Bauer supporting Resort Hotel Project in Sydney Harbor

SYDNEY/AUSTRALIA, June 14, 2017 – Yet another distinctive building will soon adorn the skyline of the largest city in Australia: The new Crown Sydney Hotel Resort is currently being built in the Barangaroo South district. With 69 floors and a height of 275 m, the hotel will be the tallest habitable building in the city. Bauer Foundations Australia Pty Ltd and joint venture partner Piling Contractors execute the foundation work.

The first six-star hotel in Sydney, the new Crown Sydney Hotel Resort, is currently being built in the Barangaroo South district. Once completed, it will be the tallest habitable building in the city with 69 floors (including mezzanines) and a height of 275 m. It will have 350 rooms, suites and luxury apartments, as well as restaurants, bars, luxury boutiques and conference rooms. The foundation work is being executed by Bauer Foundations Australia Pty Ltd and joint venture partner Piling Contractors – having been commissioned by Crown Sydney Property Pty Limited in August 2016.

Bauer is responsible for the design and the building of the perimeter retaining wall for the basement floor as well as constructing the foundation for the building using diaphragm wall elements, barrettes and bored piles for the building foundations.
The 220 m long perimeter retaining wall will be extending several meter into the Sydney sandstone rock formations.
The core areas of the foundation are especially complex, because the diaphragm wall elements will be installed as individual barrettes with various shapes. These barrettes are used as foundation elements but also building the finishing entire sub-ground lift pit structure. The T-shaped and L-shaped barrettes require up to 500 cubic metres of concrete.

The Barangaroo site had original marine structures and old industrial gasworks. The gasworks had contaminated significant areas of the construction site. Therefore the majority of the work needs to be performed wearing protection suit and mask to protect the workforce. Another challenge for the project is the location of the site within former marine structures. These partially left in place structures on the re-claimed land require dealing with obstruction and voids during panel excavations of the foundation elements.

The Foundation Works

In total, Bauer Foundations Australia will construct roughly 8,000 cubic metres of ground improvement, 7,988 square metres of diaphragm wall up to 1.5 m thick and over 7,800 cubic metres of barrettes up to 1.5 m thick, as well as 112 bored piles up to 50 m deep and with a max. diameter of 1.8 m. A Bauer MC 96 duty-cycle crane with a trench cutter BC 40 and a Bauer BG 40 will be used. The foundation work will continue until October 2017.

Bauer returning to Sydney Harbor

This is not the first project of the Australian subsidiary of Bauer Spezialtiefbau GmbH in Sydney Harbor area. From January 2012 to June 2013, Bauer Foundations Australia, together with a joint venture partner, constructed the foundation for three large office towers and several smaller residential and office complexes on the neighboring property.
During that project, it was discovered that the top soil stratum of the former container terminal site was composed of a wide variety of back-fill material, such as brick, concrete and rubble as well as parts of old port facilities and dams. Rock with strengths of up to 100 MPa, depending on the depth, was found beneath a further layer of clay, sand and gravel. bi
