In this webinar we will look at:

  • Prestressing of precast concrete elements and considerations during their design, manufacture, and erection
  • Challenges and tips for the design and construction of high performance post-tensioned structures
  • Insight into what the PTIA is doing to ensure excellence in the post-tensioning industry.


  • Simon Hughes - Westkon Precast

Topic Title (presented by both Lyn and Haydn)
The introduction of a post-tensioning accreditation scheme to the Australian construction industry.

About this Presentation
The Post-Tensioning Scheme provides a step towards the regulation of the building and construction industry. By better educating engineers, architects, clients and owners and ensuring that contractors and suppliers are certified, we can begin to build greater trust in the building sector. Post-Tensioning Institute Australia (PTIA) and CARES Post-Tensioning Scheme will require significant investment and Government support. The PTIA is calling on all post-tensioning stake holders to get on board with this initiative.
