The green fabric that clothes the earth is fraying. Sadly, through overuse, the garment we depend upon is wearing out. The construction of buildings and urban infrastructure like roads and car parks become "dead pixels" in the living image of the planet. Repairing the old garment by stitching plants into the structures of our cities is a vital option. Incorporating plants into tall building design is an important aspect of this restoration project. This paper describes the successful installation of plants on the exterior of Melbourne's iconic Eureka Tower (see Figure 1) and provides an example of a selective vertical gardening system with a high Environmentally Sustainable Development (ESD) factor, which eliminates the requirement for plant growth substrate.

Cable net support structures present several difficulties in design and analysis due to their complexities. The analysis of an existing cable net structure for the design of new structural components reveals even greater challenges. The Showground stadium located at Olympic Park, Sydney is a 15 year old cable net supported stadium that has recently been upgraded in order to provide two newsections of grandstand seating, the southern hemisphere's biggest video scoreboard and updated amenities. During this upgrade, the end tie-down cables that supported the existing roof needed to be removed and relocated to positions on the new structure. It was required to analyze the existing cable structure using advanced finite element modeling techniques in order to determine the cable forces involved in the modification and construction of the expanded stadium. This paper provides an insight into the development of the finite element model used for the analysis of both the existing roof structure and the new stadium sections for both design and construction. It also explores the issues associated with the introduction of unknown load paths that occur in practice into finite element models and the need for accuracy when modeling them for an existing structure that is to be altered for further construction. Utilizing the developed finite element model to determine the cable forces of both the new and existing structure through all stages of construction, the techniques applied in modeling the stadium were validated by the structure's response being within 2% of the results extracted from the finite element package. © 2013 Taylor & Francis Group.

Auckland City Council set up an international design competition for an opening bridge and, after two hotly contested stages, selected the striking design prepared by Hyder Consulting with architect Denton Corker Marshall and mechanical and electrical consultant Kenneth Grubb Associates. The project's aspiration was to create an iconic object, a breathtaking symbol for Auckland embodied in a unique and distinctive structure. Iconic status demands differentiation and, in the case of opening bridges, this can be provided by the built form, operation and scale. The Te Wero design responded to this challenge with a solution targeted specifically at the Viaduct Basin's unique history and environment. This paper considers the function and visual aspects of the bridge, its form and image, together with consideration of materials, design and construction issues that led to the final bridge design. The design is for a twin bascule bridge, with a tall mast structure that houses counterweights and a control room. When it opens, the effect will be dramatic, with the twin decks rising to either side. Thanks to lightweight aluminium decks and an ingenious counterweight system, however, it will be a low-energy, low-maintenance and sustainable solution. © ICE Publishing: All rights reserved. Source

The Astor Apartment Building in Sydney was completed in 1923. After almost 90 years in service, the façade had deteriorated to a point where major intervention was required to conserve it for the future. Previous remedial works failed to arrest the ongoing corrosion of the windows to a point where most had deteriorated and now necessitated intervention. A study of options for repair and conservation was undertaken with the poor condition of the steel windows meaning that replacement was the most technically and economically viable option. The Astor Façade Conservation Project involved concrete repair and protection as well as high performance protective coatings to new steel windows to manage the corrosivness of the environment. In addition, elements of building sustainability and energy efficiency were reinstated and improved by the refurbishment. Copyright © (2012) by the Australasian Corrosion Association. Source

Conservation works to the facade of the heritage listed Dymocks Building located in George Street, Sydney have recently been completed. The building was constructed in the mid-1920s by the Dymocks Book Arcade. The George Street elevation of the Dymocks Building consists of glazed terracotta (faience) cladding, moulded copper panels and painted steel-framed windows, over a concrete-encased steel structure. The terracotta cladding showed localised areas of cracking and spalling associated with corrosion of embedded structural steel elements and movement of the building structure. This presented a developing risk to public safety. The project team devised a two phased approach to the repair and conservation of the façade, namely: Phase 1: Facade Deconstruction and Phase 2: Facade Reconstruction and Conservation. Source
