CROSS LAMINATED TIMBER (CLT)


CLT is a renewable and sustainable building material that has commercial, build-safety and finish-quality advantages over conventional building practices.

We have developed the resources and experience that allow us to provide specialist CLT design services across Australia – from single storey residential homes to large institutional or multi-residential projects.


 

About


VISTEK & CLT


Mission:

Over the last 5 years Vistek has committed to developing our expertise in Mass Timber construction, specifically CLT.

We are strong believers in the need for the construction industry to move to a more sustainable and lower-carbon model. We see it as our responsibility as engineers that we develop the skills and experience in Mass Timber design and construction to enable us to help the local industry make this transition.

Capabilities:

Our staff has trained at courses both locally and overseas and are active participants in the field of timber engineering, attending conferences such as the World Timber Engineering Conference and also presenting at local timber engineering workshops.
We have also expanded our analysis software platforms to include key timber design programs developed in Europe. These allow us to design more efficiently for timber structures and also to more accurately analyse hybrid structures incorporating steel and concrete elements.

Network:

Through our involvement in the timber design community, our network now includes other CLT experienced construction professionals such as architects, fire engineers, building surveyors, CLT suppliers, CLT builders and timber experts. This network gives Vistek the breadth of support required to help our clients beyond just executing the structural design and ensuring that your project becomes a reality.

CLT Quote


“The last 12 months have been an exciting time for CLT in Australia and we have seen an upswing in projects coming through the office – both small and large scale.

 

With the announcement that Australia will be getting its first local CLT plant it appears that this momentum will only get stronger.”

CLT Sectors

SECTORS:

RESIDENTIAL

On a materials “like-for-like” basis CLT may not always compare favourably cost-wise for single residential buildings. However, when build speed, finish quality, sustainability and energy efficiency are also considered, CLT can be a superior option to conventional building. Key features of CLT for residential developments are:

  • The rapid erection schedule means that projects are much faster to get to “lock-up” and therefore to move in. This can reduce costs if alternative rented accommodation is required during works.
  • For sites with poor access, structural elements can be craned into position, simplifying the erection process.
  • For sites with little on-site storage, CLT offers a just-in-time materials delivery advantage.
  • Two storey buildings have many fewer working at height issues and therefore reduced costs and risks.
  • CLT sequesters carbon.
  • The thermal performance and tightly sealed building envelope CLT delivers provides a good basis for a highly energy efficient home. CLT has successfully been used for “Passive House” buildings.
  • CLT’s mould resistance and natural humidity regulation makes for a healthier internal environment.
  • Exposed CLT can reduce the need for plastering, providing additional time and cost savings.
  • The high accuracy and forward planning of CLT design allows for much easier installation of finishes including joinery, flooring and tiling.

RURAL AND COASTAL

The advantages of CLT noted in the “Residential” sector have additional advantages for Rural and Coastal sites.

  • The reduced need for separate trades and highly skilled labour is a particular advantage in more remote areas where coordination of labour can be difficult.
  • Pairing CLT with concrete-less footing solutions can rapidly reduce installation time and eliminate the need to get concrete to a remote site.
  • Getting to lock-up quickly can reduce the risk of delays due to weather, materials delivery, labour coordination and sundry other scheduling disruptions.

MULTI-RESIDENTIAL: TOWNHOUSES AND TOWERS

A multi-residential mid-rise project carefully designed for CLT from the outset can provide a high quality with lower costs than a conventional build (RC/PC concrete, steel frame, etc).

The Stadhouse (UK) and Forte (Australia) projects have provided proof of concept where buildings that would take months to build with a team of 40+ can now take weeks to build with a team of less than 10.

Vistek are currently working on several multi-residential projects that are either CLT only or Hybrid CLT (with steel and/or concrete).

EDUCATION AND HEALTH

CLT provides special benefits to Education and Health projects:

  • CLT’s rapid erection process and the relatively small disruption to areas surrounding site (the loudest noise on site will be a power drill) means that for schools, hospitals and care providers their usual operations can continue with very little interruption from the building process. Some projects may achieve lock-up in a period shorter than a term break.
  • Mass Timber structures provide healthy internal environments that are suited to both scholastic and care giving environs.

HOTELS AND ACCOMMODATION

The regular and “honeycomb” arrangement of large accommodation complexes, such as hotels, hostels and resorts, lend themselves well to CLT construction.

  • The fast erection speed means that the building can be generating revenue quicker.
  • With careful detailing, excellent acoustic performance can be achieved between rooms.
  • High energy efficiency can be achieved that will reduce the running costs ofbuildings.
  • Exposed CLT can help achieve high-end architectural details without any additional cost.

VERTICAL EXTENSIONS

CLT’s prefabricated and lightweight credentials make it the ideal material for Vertical Extensions atop existing buildings.

These advantages are particularly helpful in inner-city sites where access is difficult and work may be restricted to certain periods of the day.

CLT Quote 2


One cubic meter of wood will store one tonne of carbon dioxide. Now our two solutions to climate [change] are obviously to reduce our emissions and find storage. Wood is the only major building material I can build with that actually does both those two things.

 

So I believe that we have an ethic that the Earth grows our food, and we need to move to an ethic in this century that the Earth should grow our homes”.
