Innovation is key for productivity improvement and advancements in different sectors of the economy, including the construction sector. The criticism of the slow pace of innovation in construction industry may be unwarranted, considering the structure of the industry and nature of the construction business. The loosely coupled nature of firms, mostly Small and Medium Enterprises (SME’s), delivering ‘projects’ through partial engagement, together with the distinction between the project innovation and firm innovation makes it difficult to extract innovations in a meaningful way. The problem also lies in conceptualising, defining, articulating and assessing innovation in construction. The literature is replete with research into construction innovation, however, there is limited research into understanding how innovation is perceived and narrated in practice. The paper aims to explore how innovation is assessed and narrated in construction, specifically analysing theory and practice perspectives. A theoretical model was constructed from a structured literature review illustrating existing discourse and narratives of construction innovation assessment. A qualitative analysis of ‘Professional Excellence in Building’ submission documents to the Australian Institute of Building was performed to identify the practice perspective of innovation. The findings suggest that internal organizational and process innovation account for the majority of improvements identified. Importantly a taxonomy of narrative is developed that articulates how the construction industry in Australia views industry innovation.

Since the late 1970s, Complexity Scientists have shown that many natural systems possess similar geometric patterns that are repeated over multiple scales of observation. This observation lead to t...

Purpose: In the fast-changing field of zero-carbon construction there is a gap in understanding how zero-carbon construction strategies are experienced in practice. This paper aims to identify the key barriers and enablers to driving a zero-carbon construction strategy by industry, policymakers and educators. Design/methodology/approach: The research was conducted in two stages. The first stage used a literature review to determine thematic areas from which to develop discussion points for the second stage of the research, which gathered insights into key barriers and enablers to driving a zero-carbon construction strategy from analysing recorded discussion with industry, policymakers and educators. This study adopts a qualitative research methodological design underpinned by dialectical approach of enquiries involving 31 participants. The philosophical standpoint aligns with a constructivist participatory worldview based on multiple stakeholder perspectives. Data involving virtual and face-to-face engagement held simultaneously in Australia and India were transcribed, coded and synthesised to identify the barriers and enablers to driving zero-carbon construction strategy. Findings: The paper identified key barriers and enablers driving zero-carbon construction strategy. Barriers included limited awareness of industry dynamics; fixed mental models of professional practice; complexities in identifying appropriate skillsets; difficulties associated with reviewing education and training models and integrating sustainable strategies at early stages of projects. Enablers included: fostering education reform and supporting frameworks and procurement strategies for developers and clients; implementing efficient building designs, construction and operationalisation of zero-carbon buildings and; utilising an industry-led integrated approach. A framework was developed to provide an illustrative view of the linkage between the research projects’ focus areas and emergent themes. Originality/value: The paper provides zero-carbon action priorities for four significant stakeholder groups in the build environment, developers, building occupiers, educators and government. As the priorities are derived in the research from examination of current literature and analysis of stakeholder viewpoints, this paper presents a unique, realistic and timely identification of barriers and key enablers driving zero-carbon construction strategies. Methodology applied in terms of data collection involved a public discourse and a unique technology-driven collaborative approach where participants simultaneously contributed across countries and time zones in a synchronous manner across key topics related to driving the zero-carbon construction strategy.

Purpose: Frank Lloyd Wright's famous house Fallingwater has been the subject of enduring scholarly debate centred on the allegedly clear parallels between its form and that of its surrounding natural setting. Despite these claims being repeated many times, no quantitative approach has ever been used to test this argument. In response, this paper uses a quantitative method, fractal analysis, to measure the relationship between the architecture of Fallingwater and of its natural surroundings.Design/methodology/approach: Using fractal dimension analysis, a computational method that mathematically measures the characteristic visual complexity of an object, this paper mathematically measures and tests the similarity between the visual properties of Fallingwater and its natural setting. Twenty analogues of the natural surroundings of Fallingwater are measured and the results compared to those developed for the properties of eight views of the house.Findings: Although individual results suggest various levels of visual similarity or difference, the complete set of results do not support the claim that the form of Frank Lloyd Wright's Fallingwater exhibits clear visual similarities to the surrounding landscape.Originality/value: In addition to testing a prominent theory about Wright's building for the first time, the paper demonstrates a rare application of fractal analysis to interpreting relations between architecture and nature.

In the context of flood research, scholars and practitioners have recognised that Western-knowledge-driven engineering-based flood management techniques are insufficient for successful water use and management in urban design and planning practices, while ideas, practices, and knowledge from local people are essential. Traditional water knowledge (TWK) explains people’s profound understanding of natural processes and the ecological dependencies of water systems and connections with their local water system and the land, beliefs, sense, and practices that are an integral part of their culture. However, the concept of traditional knowledge may differ from scientific knowledge, as it represents a different worldview perspective from a modern Westernised world. Considering Khulna City, Bangladesh, as a case, this paper investigates the salient challenges and opportunities to integrate TWK with present urban design and planning practices. Interviews were conducted with key stakeholders, including relevant government officials, NGO workers, researchers, urban professionals, and local elders. This study finds that TWK can contribute to urban design and planning practices by identifying helpful ecosystem services and site-specific information; by sharing strategies for surface water protection, open-space design, and rainwater harvesting; and encouraging design of spaces for psychological benefit, and ensuring sustainability and building flood resilience in an urban context. Furthermore, this research demonstrates how these elements relate to the Sustainable Development Goals (SDGs). However, issues with knowledge transmission, the identification of the actual knowledge holders, poor governance, weak urban planning, minimal institutional capacity, and perceived cultural inferiority are significant challenges restricting the integration of TWK, despite its relevance to sustainability. This paper suggests that considering traditional water use and management is necessary to develop flood resilience in an urban context in a sustainable way.

Over the last two decades, a range of computational techniques have been developed for measuring the formal characteristics of architecture. One of the most widely used methods, fractal analysis, measures the typical or characteristic spread of visual information (form and texture) present in a plan or elevation. However, when preparing a plan or elevation for this method, several critical decisions must be made about which architectural features should be included in the representation and why. Without a consistent, reasoned way of making such decisions, isolated fractal dimension results for buildings are potentially meaningless. Therefore, the present paper draws on postpositivist reasoning to propose a framework for deciding which lines in an architectural representation are significant for a study and why. The framework contains five cumulative levels of representation that are defined and mapped against comparable research agendas. These levels are described and demonstrated using a plan and an elevation from Le Corbusier's Villa Jaquemet. In each case, the results of the fractal analysis of different representations of the Villa are used to demonstrate how decisions about significant lines have a direct impact on measures derived from fractal analysis.
