learning oBjectives

At the end of this program, participants will be able to:

1. Learn how cross laminated timber is challenging current building practices to create buildings that are faster to erect and better for the environment.

2. Evaluate the attributes of CLT that can reduce a buildings carbon footprint

3. Understand how the use of CLT can significantly reduce the typical construction schedule of a mid-rise building

4. Learn how CLT buildings contribute to sustainable communities.

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.

lend lease & cross laminated timBer

Lend Lease are assessing the viability of utilising CLT to deliver select projects across their portfolio. The viability of CLT will rely on:

Economic procurement and importation of timber and/or establishment of a local timber supply and production facility.

Provision of a cost effective alternative to conventional structural solutions.

Resolution of technical issues design & delivery.

Market acceptance.

WHy cross laminated timBer?

Original driver: alternative solution for North Wharf (Vic Harbour) to reduce in ground costs.

Offers an opportunity to commercialise sustainability.

Envisaged shorter construction times to provide more opportunity for development feasibilities to meet threshold requirements.

Reduced tolerances facilitating off-site manufacture.

Detailed technical due diligence and market research to proof the CLT business case between 2009-2011.

Culminating in design & delivery of Fort as the pilot project for utilising CLT.

If the 19th century was the century of steel, & the 20th the century of concrete, then the 21st century is about engineered timber

WHat is clt?

Austrian Spruce

WHat is cross laminated timBer?

Planks of kiln-dried, finger-jointed spruce are sorted and cut into sheets of up to 16.5m by 2.95m.

The sheets are then stacked and glued under high pressure in perpendicular layers.

The process involves a high-pressure bonding system which allows the use of polyurethane adhesive in the boards solvent-free and formaldehyde-free.

Crosswise glueing at high pressure reduces the woods expansion and shrinkage to an insignificant level.

The panels are cut and processed CNC technology, resulting in excellent dimensional stability, both in overall panel size and for structural openings.

construction using cross laminated timBer

The CLT panels form a cellular structure of timber load bearing walls with timber floor slabs.

The solid wood panels are used as plate, wall & diaphragm members.

Joints are secured with screws & angled connection plates.

timBer as a material

Timber is the only renewable structural building material of scale

Forests act as a carbon sink - each tonne of CLT has sequestered ~1.6 tonnes of CO2 (~0.5tonnes of carbon locked-in)

Timber has the lowest energy consumption of any building material of scale across its life cycle

Sourced from sustainably managed forests

key BeneFits

sa

Fe

Reduced high risk work (eg work at heights). Elimination of injuries associated with formwork and reinforcing

Better work environment with less dust, less vibration and noise and less obstructions (no propping), thus reducing the impact of construction and disruption on local communities

Fewer operatives on site and for a reduced period of time

key BeneFits

Sustainably sourced timber is the only carbon neutral structural option 1m of timber stores 0.25t of carbon

Timber has better thermal performance than reinforced concrete (reducing dependence on synthetic carbon based insulation)

The production process generates zero waste

Reduces fresh water consumption compared to reinforced concrete (up to 30 times less per m3)

Enhances Indoor Environment Quality and positive effects of timber environment (zero VOCs)

Reduces pollution on site i.e. noise, dust and contamination of water (eutrophication reduced by 75%)

Reduces the deliveries to site compared to reinforced concrete (up to 7.5 times less)

key BeneFits

20% of the weight of the conventional structure

Reduces foundations due to lighter-weight construction as compared to reinforced concrete

Assists with poor ground conditions of sites such as Victoria Harbour

key BeneFits

Reduced Preliminary & Supervision costs due to speed and efficiency of the construction methodology

Savings in follow-on trades as the material is easier to work with than concrete - conduits are pre-cut and the panels are flush fitted

Reduced holding costs

High precision and quality control leading to reduction in long term maintenance costs

key BeneFits

Further step change efficiency improvements in conventional construction are very limited

Undertaking a CLT pilot project will verify the step-change improvements that can be expected from CLT

The pilot project will allow Lend Lease to identify areas for optimisation of the construction process which may lead to further significant efficiency improvements and project savings

Construction productivity & efficiency improved as compared to reinforced concrete

The use of BIM from design to manufacture and construction enhanced
