Projects: Central Park Sydney
The 5.8 hectare site is on the Old Kent Street Brewery which was established in 1835. The site was acquired by Frasers in 2007. Whilst the majority of old brewery has been demolished, the coal hoppers, boiler rooms and the 54m high chimney and associated structures have been preserved with heritage listing.
Frasers have worked with conservation groups, architects and heritage consultants to ensure that this important part of Sydney’s history is able to have a new lease of life breathed in to it whilst embracing and celebrating its past. Inside the old brewery the buildings past will be honoured with restored brewing machinery and paraphernalia being incorporated in to this exciting new space.
Urban Energy have been engaged to supply and install the thermal exhaust system for the new plant room that will supply power, heating and cooling to the Central Park development. The exhaust fumes need to discharge at a high level so that the plume does not affect the residence living in high rise apartments, the existing chimney was ideal for this except the variation the temperature of the gases being vented could cause damage to the old brickwork. It was decided to install stainless steel free standing flues with in the chimney, preserving the brick work and the heritage aesthetics.
Getting the flues in to the chimney required a lot of careful planning and coordination, between the builders Total Construction, Urban Energy and Structural & Civil Engineers Kneebone, Beretta & Hall. With space within the 54m chimney being very tight the lower 8m section of the chimney was installed first via the base and the remaining 46m then lowered on to it in sections from the top of the chimney.
A 450 tonne capacity mobile crane was engaged to lift the sections in to place. The crane had to lift sections of flue weighing 12 tonnes over existing buildings and up to such a height that approval from Sydney Airport had to be obtained due to the sites location on the flight path. At its highest the top of the crane was 110m above street level. A two man team located at the top of the chimney guided the flues down the shaft and in to position.
Whilst being a complicated and delicate procedure the whole process passed off smoothly and without event, aside from gathering a crowd of onlookers at this spectacular event.
