Transcript of Untitled Prezi

The Resistance to the Implementation of Innovative Walling Systems in the Australian Residential Construction Industry Alexandra Chung, John Touma and Wilson Zhang The current Australian
residential construction industry Surge in housing demand and property prices
Increase in dwelling construction
Maintained the same conventional construction since 1900's Innovative Walling Systems AFS LogicWall (AFS)
Dincel Construction Systems (Dincel)
Zego Insulated Concrete Forms (Zego) Objective Assess the industry's resistance to change from conventional construction methods to new innovative techniques The Research Investigation Compare supplier and industry opinions of systems
Cost comparisons against conventional
Analyse industry's awareness of innovative systems Three Methods of Investigation Preliminary Research
Supplier Interviews
Industry Professional Interviews Preliminary Research System functions and construction process
Establish comparative conventional techniques
Sources from company brochures, articles and specification books Supplier Interviews Features, awareness limitations
Open-ended questions
Hands on experience
prompted discussion
Residential costing plans Construction industry
professional interviews Attitudes and resistance toward systems in the industry
Mixture of structured questions to enhance results
Eighty-six interviews conducted and analysed Common Benefits
Reduced overall construction time compared with traditional masonry construction
Reduced need for scaffolding and cranage
Reduced amount of labour required
Increased OH&S on site
Overall reduction in project cost AFS LogicWall Permanent formwork system comprised of fibre cement sheeting bonded to galvanised steel studs
Steel reinforcement placed within the formwork core
Load bearing wall when filled with concrete AFS LogicWall
Advantages Prefabricated (including corner pieces) and cut to size
Easy installation of services
Fibre cement sheeting does not require finishes
Reduces craneage by 80% Dincel Construction Systems Modular, permanent formwork system made from rigid, lightweight PVC channels
Uses patented 'snap' together joints
Load bearing wall when filled with concrete Dincel
Advantages Completely waterproof system
Quick installation by unskilled labourers
No crane requirements due to lightweight nature
Built in conduits provide easy installation
Crackproof Zego Insulated Concrete Forms Permanent, expanded, polystyrene, interlocking block formwork
Joined by patented locking system
Structural element when steel and concrete is placed
Zego Advantages Exceptional thermal advantages (up to 10x more than masonry)
Flame retardant
'Dove tail ' grooves allow easy rendering and plaster adhesion
Quick installation by unskilled labourers
No craneage required due to lightweight nature
Easy service installation Conventional Construction Techniques Research and industry surveys concluded
Single Brick Veneer: Single Dwelling
Double Brick: Single and Multi- Dwelling Resistance to Implementation Mate Mentality Unwillingness to Learn Unfamiliarity = Risk Bad Reputation Client Skepticism Lack of Understanding Limitations to the Methodology Number of interviewees was limited
A large number of interviewees were referred by the system suppliers
Cost analysis limited by broad scope Conclusion The innovative systems all provided distinct advantages over conventional methods
All systems have potential for further recognition
There are a number of points contributing to the resistance of implementation in the industry
