Building Overview

Existing Brick Facade

Brick Layering Anchored to Steel Frame

Panelised Curtain Wall

  • Curvilinear brick facade was quite the engineering achievement
  • Relies on mechanical ventilation
  • Frank Gehry pushed the boundaries of architectural form
  • Location: University of Technology, Sydney - UTS Business School
  • Completed 2014
  • 14 Levels (11 Occupied + 1 Basement + 1 Plant + 1 Rooftop
  • Architect: Frank Gehry

Brick Layering Anchored to Steel Frame

  • Use of undulated bricks: created texture, aids in offsetting rain

Movement Joint Strategy

  • High-performance glazing used throughout
  • Used custom design 'groove & bolt system'
  • Many challenges throughout the construction process
  • MJs face-sealed on-site & supported on each transom
  • Majority of sun enters the building in the afternoon
  • Five types of custom made bricks

Inner steel frame which

supports brick cladding

  • Current facades are the best solution for this project due to cost of construction & quality control
  • Shading devices mounted indoors to provide daylight control

Waterproofing

Brick-tie arrangement for near vertical facades (left) & steeper facades (right)

  • Shading from nearby buildings
  • Sealants used between panels

Movement Joint Strategy

SWOT Analysis

  • Bricks are porous: expand with moisture
  • MJs essential to avoid cracking, detachment or water ingress
  • Panels pressure equalized
  • Facilitate brick expansion, MJs located vertically & horizontally
  • Insulation: reduces heat transfer from building envelope
  • Supported on a floor by floor basis

Waterproofing

  • Gutter system & downpipes
  • Curving facade makes waterproofing & water drainage a critical issue
  • Waterproof membrane used
  • Window boxes were face-sealed
  • Capping used on window frames & glass roofs

  • Inspired by a Treehouse - focus on fluidity & movement
  • $20 million donation from Dr Chau Chak Wing
  • $180 million total
  • 5 Star Green Star Design Rating
