Our CIA calendar opens in 2019 with our Project Review seminar highlighting the Brisbane landmark project - Sky Tower.   The building being constructed by Hutchinson Builders will be the tallest residential tower in Brisbane standing at 270 metres.  The seminar will provide details on different aspects of the design, construction and materials.   The project also presented various challenges during the construction, which will be reviewed with the solutions developed to enable milestones to be met.

Sky Tower
Structural Design and Construction
Richard Cass - Bonacci Group

The shape of a tall tower and how it interacts with the wind is an integral part of its structural design. The internal structural form is also typically governed by movement considerations of lateral sway and axial shortening. This presentation covers the fundamentals of tall building structural design and construction applied to the Brisbane Sky Tower project.

Structural innovation put into practice by Australia’s leading Building Contractor
Lynden Watson - Hutchinson Builders
Awarded in 2015, Sky Tower is Hutchinson Builders biggest and most complex contract. In this presentation Lynden will delve into the structural challenges presented to the team and the innovations that led it to become so successful.
As Project Manager, Lynden was lucky enough to be part of the project from its tender award and will see its completion through in June 2019.  He has been with Hutchinson Builders since 2007 working on a variety of projects from education, mining as well as residential, hospitality and commercial. Lynden holds a Bachelor of Science in Construction Management obtained from the Queensland University of Technology.

Challenges around the supply of concrete
Michael Booy - Hanson

Sky Tower involved the supply of high strength super workable concrete for vertical forms as well as high slump concrete for the floor slabs. This was pumped up as high as 91 levels in a single stage. The challenges around the supply of concrete will be explored as well as a general outline of how these were overcome.

Slab Design and Construction
Dominic Brock  - ADG Engineers
The design of post-tensioned slabs for a tall tower shares the fundamentals with other buildings, however there are a number of issues that differentiate them from normal design. Due to the nature of the structure and construction methodologies adopted, there are considerations that need to be made for slab restraint, continuity, lateral loads and early age construction loading. This presentation covers the fundamentals of slab design and construction for tall buildings applied to the Brisbane Sky Tower project.
