“ the time is not far off when companies will have to justify their worth to society, with greater emphasis being placed on environmental and societal impact than straight economics.”
The WORld’s TallesT TimbeR apaRTmenT building– a land mark innovative project by lend lease
– forté is another great example showcasing lend lease’s integrated business model with the project being conceived, designed, developed and constructed by lend lease.
– first Clt building in australia
– targeting first 5 star green star residential (as built)
– first lend lease australia project to incorporate pods
– High profile location
whaT Is CLT?
austrian spruce
whaT Is CLT?
– stable engineered product
– highly mechanised production process
– simplicity - basic assembly concepts
– scale - large panel dimensions that suit major commercial construction
– robust

key beneFITs FROM OUR PeRsPeCTIVe
– reduced high risk work (eg work at heights). elimination of injuries associated with formwork and reinforcing
– better work environment with less dust, less vibration, noise and obstructions
– reduced impact of construction and disruption on local communities
– Fewer operatives on site and for a reduced period of time
sUsTaInabLe– Carbon neutral structural option – 1m³ of
timber stores 0.25t of carbon
– better thermal performance
– Generates zero waste
– reduces fresh water consumption
– enhances indoor environment Quality
– reduces the deliveries to site
key beneFITs FROM OUR PeRsPeCTIVe
x 90% Less
LIGhT weIGhT– 80% weight reduction
– less mass to support
– reduces foundations
– assists with poor ground conditions
– basic craneage
key beneFITs FROM OUR PeRsPeCTIVe
TIMe saVInGs & eFFICIenCIes– reduced preliminary & supervision costs
– savings in follow-on trades
– reduced holding costs for developer
– high precision quality
key beneFITs FROM OUR PeRsPeCTIVe
The ChaLLenGessome things developers aren’t fond of:
– products that are not used locally
– limited long term performance history
– making customers nervous
– solutions with added finance or insurance risk
– asking builders to change their habits

Uk/europe– building regulations: Clt is compliant– Codes of standard for design: eurocode 0 – basis of structural design eurocode 1 – actions on structures eurocode 5 – design of timber structures
australia– building Code of australia deemed to satisfy code does not consider a timber building above 3 stories– Codes of standard for design: as 1170 – structural design actions as 1720 – timber structures – design methods
Solution is therefore a fire engineered ‘Alternate solution’
FIRe PeRFORManCe technical
– highly predictable performance.
– layers char at 0.7mm / min.
– sacrificial layers and / or supplementary materials can be used.
– Forté uses a combination of protection and sacrificial.

aCOUsTIC PeRFORManCe technical
– equal or higher than conventional concrete frame / masonry / plasterboard wall
– Focus on low frequency – need to add mass via floor build up
– australia has high code requirements
– lend lease has higher than code standards
dURabILITymoisture Protection
– rain screen facade
– moisture content should be around 12%.
– Controlled “by design”.
– Clt protected by sarking and cladding.
– Ventilation cavity draws heat away from the timber.
– moisture detector sensor rods strategically located within the Clt.

VeRMIn – whaT abOUT TeRMITes?
Vermin protection:
– Code requires timber structures to be protected from termites
– Clt structure sits on concrete podium for ground seperation
– physical termite barriers at perimeter and services penetrations (chemical free)
– annual inspection regime
desIGn PROCess & TeChnICaL deTaILInG
IT Is a dIFFeRenT desIGn / COnsTRUCTIOn PROCess
– all design completed up front– File to factory process– 3d modelling in auto-Cad– installation sequencing, crane calculations – minimises waste, reduces onsite decision
making and errors
whOLe bUILdInG PROTOTyPe ObjeCTIVes:
– Create a market facing product
– achieve 5 star green star (as built)
– achieve authority approvals
– resolve technical detailing
– achieve a fit-for-purpose product
– demonstrate Clt as viable alternative
– Constructibility – impact on design process – impact on other building tasks
– a base case to leverage step change improvements in future Clt projects
