Low-level noise generatedduring the cutting cycle may be heard in buildings near the TBM,depending on the location and building size. For this reason andin compliance with Environmental Protection Department (EPD)regulations, the TBM would generally not operate at night.Detailed noise and vibration monitoring were also undertakento ensure compliance with the limits set.The TBM moved along at about 40 metres per week, andresidents were always advised of the TBM’s location andprogress throughout the tunnelling operation.Plastic formwork at Australian Embassy in Phnom PenhLeighton Asia is using a Vietnamese company’s leading-edgelightweight, plastic injection-moulded formwork system forthe structural works on the Australian Department of ForeignAffairs and Trade’s new Australian Embassy project in PhnomPenh, Cambodia.Works include a three-storey Chancery building with qualityfinishes and high-level security.

The US$14.6 millionLeighton project is scheduled for completion in 2009.with Wynn Resorts Group. It is on track for completion in thefirst quarter of 2010.The very confined site is immediately adjacent to the existingWynn Casino which operates 24 hours a day, seven days a weekand is accessed daily by 7,500 employees and 25,000 guests.In response to client concerns and tight programme deadlines,Leighton introduced two innovative approaches not previouslyused in Macau, a top-down construction of the basementconcurrent with the construction of the podium above, resultingin a significant reduction in timelines, and the introduction of aspecialist jump form system for the entire footprint of the tower.With podium levels rapidly progressing and basementconstruction complete, focus has shifted to the typical towerfloor construction where Leighton is pushing the envelope oflocal expertise and combining it with the best technologiesavailable. Rather than using the typical Hong Kong-style jumpform at the core walls only, Leighton has chosen to apply thetechnique to the entire building footprint.The client is delighted with the Leighton approach to the projectas it addresses safety concerns, whilst also raising a high profilefor the development.Panel developer, Vietnam’s Fuvi Mechanical Technology ofHo Chi Minh City, worked with Leighton’s site managementteam in Phnom Penh to customise the formwork systemspecifically for the Australian Embassy project.Leighton contributes to high profile of Macau resortLeighton Asia is utilising state-of-the-art Australian jump formtechnology and expanding its use with local expertise in relationto key projects across the Asia region.
