12:00 PM - 5:10 PM


James Cook University
The Science Place Building 142, Room 111 , Townsville Qld 4811


The North Queensland Concrete Engineering and Technology Seminar is an important annual event organized by the Concrete Institute of Australia North Queensland Sub-Branch Committee in partnership with James Cook University.


This year the seminar focuses on the various design issues in concrete industry. Distinguished academicians and professionals will share their knowledge on different aspects of concrete design and construction. It is expected to be of a great interest to those involved in concrete technology and design including engineers, concrete entrepreneurs, concrete professionals, government agencies and engineering students.

Random cracking in concrete – its causes and how to minimise it
Unplanned cracking in concrete remains a key issue of disputes and litigation.  This holds particularly for early age cracking but is not limited to that alone. 
This presentation discusses causes of random cracking such as plastic (and later-age) shrinkage, plastic settlement, thermal effects, chemically effects and so on, along with other defects such as delamination. It addresses construction practice and specification to minimise these random defects.
The presentation features real examples with detailed discussion of what went wrong and what might have been done to avoid the problem.  It draws on research information presented in a practical manner of use to the engineer and the contractor.

Joint Design and Management in Industrial Floors, Residential Slabs and Pavements
When considering Joint Design and Management for concrete Slabs-on-Ground, current design methods utilise the most prominent standards and guidelines from around the globe as best practice:
  • ACI360R-10 - Design of Slabs on Ground – USA Standard
  • TR34 – 4th Edition - Concrete Industrial Ground Floors – UK Standard
  • CCAA T48 – Guide to industrial floors and pavement – AUS Standard
  • AS3727 – Guide to residential pavements – AUS Standard 
A key consideration in Joint Design is the role of the floor. What is the asset owner’s intended use for the floor? How can Joint Design protect the asset, and prolong the working life of the floor? Typically, industrial floors are subject to the wear and tear of materials handling equipment such as forklifts and cherry pickers, and as a result, joints are susceptible to damage from such equipment.
Load transfer is crucial in the design phase of an industrial floor. It is imperative to (1) understand the different dowel types available and their performance capabilities, (2) the design capacities of steel vs. concrete, and (3) the impact of concrete stresses on joint performance. Design methodology must also extend to consider the practical fabrication of the joint. This will include, correct placement of dowels (i.e. in accordance with manufacturer’s installation procedures), correct reinforcement placement and both the timing and depth of saw cutting. Other practical joint features that need to be considered may include edge protection, PT fabrication and possible areas of restraint.
When combining good sound design practices with best practice of joint formation during construction phase, the likely outcome will be flatter concrete floors with minimal cracks, spalling and curling, providing longer service life of Slabs-on-ground, potentially saving asset owner thousands of dollars.
Key learning outcomes:
  • Who benefits from a quality slab or pavement?
  • What issues cause down time, repair cost and insurance claims?
  • Understanding the role of the floor. Designing a floor that will carry the load?
  • Do you understand the performance of your dowels or load transfer system?
  • Constructing it right: Is the floor being built to specification?  Designing fail-safes to mitigate the risk of poor construction techniques.
  • Why is this concrete slab cracking?  What could have been done differently?
  • When should I saw cut the joints?  Is the depth specified?  Is there a good technique to curing?
  • How important are reinforcing bar chairs? 
  • Do good products, systems and design ensure a quality floor or pavement?

BIM - pitfalls and latest works Transport and Main Roads
Stuart is passionate about how we can expect the design of projects to change in the next 5 years, and what this will mean to the construction industry. He is currently managing the Ipswich Motorway Upgrade: Rocklea to Darra Stage 1 project. This is the first project TMR have implemented BIM on and he has lots of interesting discussion points to share about the future and how industry can best adjust.
