This Potts Point refurbishment is prominent on the Sydney skyline as one looks towards Wooloomooloo. The Mirvac development has required substantial steel upgrading on every floor which has been installed by Greyton's client, Tie Fabrications. There is a combination of Intumecent Paint and Vermiculite spray application to the steel providing 1 to 2 hour FRLs. Greyton has also been awarded the mechanical duct fire rating contract by Allstaff Airconditioning. This involves vermiculite spray to ducts, fan enclosures in Promat board as well as some unusual work converting an existing lift well to a mechanical duct riser. The systems are to be fire separated in this case and two 19 story fire barriers will be installed by Greyton which will be achieved with a vermiculite barrier system.
 

This latest edition to the King Street Wharf development by Multiplex involves some major mechanical duct systems including multiple Kitchen exhaust systems. Greyton has been contracted by JL Williams to undertake this project with large duct runs and fans. The ducts will be sprayed with Vermiculite while fans will be housed in fire rated enclosures. These enclosures will be constructed in Promatect L500 calcium silicate boards. Other works include sealing of electrical penetrations for Roles Electrical.

Currently underway this heritage redevelopment is being carried out by Mirvac and Transfield and has offered some significant challenges for Greyton. The main works involved removing lead paint from existing steel facade beams and fire rating them with Intumescent Paint. This process has been detailed under 'Steel Protection'. The FRL requirement was 2 hours which meant achieving a dry film thickness of up to 4mm in some areas. Other works completed include joint sealing, Vermiculite spray to steel and ducts, sealing of services penetrations and constructing fire rated bulk-heads in calcium silicate boards.
 

Greyton is almost complete with all works for Barclay Mowlem on this latest addition to Sydney's theatres. This new state-of-the-art theatre is surrounded by heritage buildings that were used for storage of grain, wool, etc at the old docks around the turn of the century. The Bond Store buildings as they are known were constructed with timber floors supported by heavy cast iron columns shipped in from the UK. The fire protection of some 60 of these columns was the task of Greyton and maintaining the heritage appearance was the goal. There was also a substantial amount of new structural steel installed to support the renovations and this was all protected with Intumescent Paint, providing a 2 hour FRL. Vermiculite spray was used on three huge heritage beams that spanned over 30m between Bond 2 and 3 with a depth of 1.8m.
