PRESENTER: Michael Tyrrell.
TOPIC: A review of QDC MP1.4 – Building Over or near relevant infrastructure, and the changes to Queensland Urban Utilities (QUU) Build Over Asset (BOA) assessment process.
OVERVIEW: As of 1st of March the QUU will no longer accept BOA self-assessable applications by RPEQ Engineers or Certifiers, this may change the time frames for assessment of Build Over Asset applications. Changes to the way QDC MP1.4 self-assessable Form 32s are lodged and checked with QUU may also impact on the time frames for approvals where a pipe is located within 3m of the building work, for class 1a and 10.
LEARNING OUTCOMES: Understanding need for and how to access QDC MP1.4. Distances to building work, pipe sizes for sewer and stormwater, acceptable solutions of QDC MP1.4. Knowledge of requirements of compliance assessments and Form 32. Build Over Asset (BOA) application process. Understand where to access more information.

TOPIC: How to specify clay masonry for fire resistance.
OVERVIEW: A large proportion of the National Construction Code (NCC) dictates requirements to ensure the fire safety of buildings. For a given building element, the means for demonstrating compliance with those requirements will depend on the building materials that comprise the element. For clay masonry walls, the deemed to satisfy means for demonstrating compliance is via AS 3700 ‘Masonry Structures’ (2018). Although clay masonry is well renowned as being a non-combustible building material, when a masonry wall is subjected to fire, expansion of the material causes bowing towards the fire source. This can lead to cracking and/or collapse of the wall. Furthermore, the thickness of the masonry must be sufficient to ensure that excessive heat doesn’t pass through the wall resulting in flammable material on the other side. Each of these elements can cause the fire to spread, and must be designed against. This presentation will explain how to specify and design clay masonry walls to meet the fire requirements of the NCC.
LEARNING OUTCOMES: After this presentation, participants will be able to: Define the terms ‘Structural Adequacy’, ‘Integrity’ and ‘Insulation’ in relation to building design. List ways FRL values are determined. Calculate the FRL for Masonry walls. Identify the suitability of a masonry wall to meet FRL requirements for a given application. Identify tools available to facilitate system selection.
