Rookwood and Holroyd Substations

Our client Alstom, is an international energy infrastructure provider and their quality requirements are second to none. This was a major challenge for Greyton, to deliver our works to a tight programme and very high standard. The substation projects include specialist blast proof and Hydrocarbon Systems which are only utilised when fires have the potential of explosion and creating super heat generated by a petrochemical oil based fuel source. Our main scope was to insulate the junctions at the precast panel walls with a Fendolite 2 system for a 4 hour FRL. There were many others applications including a Miska/Promat slip joint, Fyrestrip joints, mastic sealants and sealing of large penetrations.

With the projects 80% complete, all targets have been met and delivery of the massive transformers to the various bays went smoothly. Our combined contract value of these two sub stations is approximately $750,000.

Westfield Macquarie and Miranda

Greyton are fire spraying the all the new steel at the Westfield Macquarie Shopping Centre Project. This is the largest single contract to date for Greyton worth a total of $1.2 million applying Cafco 300 and Fendolite to the structural steel. Although this is an AMP owned Centre, Westfield are the builders and have added a substantial amount of floor space by bridging the gap between the existing building and the car park with tonnes of structural steel.

Miranda has just commenced and we will post information on that project as it progresses.

Dr Chau Chak and ITE Buildings

This amazing project is the Sydney University of Technology new Business School building under construction in Sydney, Australia. It will be the first building in Australia designed by Canadian-American architect Frank Gehry. Greyton has been contracted to provide fire barriers around the organic façade detail which is extremely unusual has its challenges due to the many varying shapes and angles. Greyton has also been involved with passive fire protection works on the Engineering Building also constructed by Lend Lease on Broadway road.

STAR Casino MUEF

Star casino is on the move again. This time a new 3000 seat Multi Use Entertainment facility is being constructed. This is a massive steel structure bearing resemblance to the Beijing Olympic Stadium with its bird nest like appearance of twisted steel members. Greyton has been contracted by Brookfield Multiplex to fire rate this structure with Vermiculite spray protecting the steel for 2 to 4 hour FRLs.

This has been a challenging project but very successful and a testament to the fantastic work done by our committed staff. Greyton has also been awarded the contract by Triple M to fire rate the mechanical ducts passing through this labyrinth and with the combined contracts, the value is over $450K.

ONE Central Park

Central Park is a multi-stage $2 billion urban village, with a collection of residential opportunities arising in stages across 8 - 10 years while Central Park takes shape. This is the first residential stage, One Central Park, designed by Jean Nouvel with PTW Architects and constructed by Watpac Constructions.

Greyton is half way through the major contract to fire rate the steel structure which includes some basement infill slabs between the towers and the support structure for the vast atrium and podiums.

Level 28 houses 4 massive steel trusses that can be seen cantilevering over the edge of the building to support a hi-tech sun light reflector and all the steel has been fire rated with Cafco 300 vermiculite.

Above the 6m high trusses the levels continue up to level 34 which are all supported by structural steel columns that have all been fire rated to a 90 minute FRL.

2 Market street

2 Market street, built by Lipman, is a complete steel structure. In Sydney's largest fire rated paint project with a total cost of $400K, Greyton has used a water based Promatect intumescent paint for the columns and beams providing up to a 2 hour rating. The FRL is predominantly 60-minutes which makes this architectural finish competitive with traditional systems. The paints were all water based which reduces fumes and minimises drying time between coats.

Cross city tunnel

Greyton was contracted by Downer Engineering and Baulderstone Haunibrook Bilfinger+Berger to carry out extensive passive fire rating to the Cross City Tunnel with a total contract value of $250,000. The contract consisted of over 600 services penetration seals, Promatect demountable fire and sound proof walls, Fendolite vermiculite spray to ducts and essential services, access panels and fire doors and fire rated bulk heads around essential services. Most of the fire barriers had to be designed for a minimum four hour fire resistant level. All work was completed to a high standard and strict programme set out by Downer and BHBB. Greyton can provided contacts for both companies if references for the above works are required. Please click the 'tunnel specialist' to see the photos of our works.

Chatswood Substation Energy Australia

Following some serious sub substation fires Energy Australia has taken action to protect their cables with various fire rated products. This can be done with spray painted ablative and intumescent coating directly to the cables or the construction of ducts that provide insulation and integrity protection. Greyton is currently inspecting the application and certifying over 200 NSW substations being treated with Hilti, 3M and other products.

In the photos on the left, Greyton has constructed a Promatect H cable duct consisting of 2 layers of 25mm H and 2 layers of 15mm H board. The top floor section is Hebel block with a steel frame housing 9 access hatches for accessing each part of the switch board The 80mm thick Promatect and Hebel will provided a fully insulated system for a period of 2 hours and integrity for 4 hours. There are a number of fire rated removable access hatches along the duct with safety signage and heavy duty handles. This work can be viewed at 'Mechanical and Cable Duct Protection'.

The Ikon Apartments

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.

Shore Apartments 6/7 and 8/9

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.

Sydney Theatre

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.

CSIRO Building

This project was completed in late 2002 by John Holland Constructions. The extent of Greyton's work mainly involved large penetration seals which carried large pipes between the floors and laboratories. Greyton was also contracted to carry out Vermiculite spray application to the mechanical duct work as well as some structural steel protection.
