  • Exploring a ‘conversational’ approach to design through the development of clay material into a biologically inspired modular dome structure
    School of Architecture Design and Planning, 2020
    Co-Authors: Sladescu Miruna
    Abstract:

    The complex architectonic structures of coral reefs and their ecosystems are beginning to fade away and disappear due to environmental stressors. Man-made artificial reef structures are currently being designed, built and sunk at underwater sites with the aim of sustaining the coral reefs. The motivation for the research presented in this thesis is to assist such coral reef sustainability efforts by contributing design knowledge to the development of artificial reef structures. Based on the writings of Gilles Deleuze, Felix Guattari, Martin Heidegger and Donald A. Schön, the research explores a contemporary method of design that resembles an interactive ‘conversation’ whilst forming the material clay into a biologically inspired modular dome artificial reef. This ‘conversational’ method enables the developing forms to be guided by the designer or craftsperson’s creative activities and by each of the ‘causes’ or forces that exist in the design environment and outside the craftsperson’s subjective thinking. To demonstrate how a ‘conversational’ approach to design can generate the artificial reef forms, this thesis focuses on the following conversing ‘causes’, influences or forces: the form, the material clay, the craftsperson and the marine microorganisms. From the craftsperson’s perspective, the design ‘conversation’ moves through a cyclical process comprising of three stages as defined by Schön. The first stage is the ‘appreciation’ stage in which ideas are formulated for the creation of the biologically inspired modular forms. The second stage is the ‘action’ stage, which occurs when all of the creative forces in the design environment are urged to undertake their work ‘conversations’, or interactions to construct the ideas. This second stage begins with the craftsperson’s activities in the workshop involving two methods of clay extrusion: direct extrusion to produce tubular modules and layered coiled extrusion to produce conical modules. Due to the clay’s unpredictable forces the modules develop with unexpected forms. The ‘action’ stage is not confined to the workshop environment; the ‘conversation’ is also extended to the underwater marine microorganisms. Prototypes of both the directly extruded and layered extruded modules are submerged underwater, extracted and observed to understand the microorganism’s unexpected organic forms that are developed over their surfaces. The third stage in the ‘design conversation’ is the ‘re-appreciation’ stage, which occurs when the developed unexpected forms of the work are observed to envisage how they can be advanced. The result of this ‘conversational’ method is an iterative sculpting of the biologically inspired modules and the dome form that they assemble into; evolving the overall dome design from a solid dome with undulating surfaces to a hollow dome consisting of perpendicularly fixed modules and finally to a spiralling hollow dome with horizontally fixed modules. This design research reveals insights that may be of value to the future production of artificial structures seeking to help preserve and sustain coral reef ecosystems. However, the development of a finalised dome design is not the primary aim of the thesis. The original contribution of the thesis lies in revealing new insights into a ‘conversational’ approach to design

  • the space time cube revisited from a geovisualization perspective
    21st international Cartographic Conference ICC 2003: Cartographic renaissance, 2003
    Co-Authors: M J Kraak
    Abstract:

    At the end of the sixties Hagerstrand introduced a space-time model which included features such as a Space-TimePath, and a Space-Time-Prism. His model is often seen as the start of the time-geography studies. Throughout the years his model has been applied and improved to understand our movements through space. Problems studied can be found in different fields of geography, and range from those on an individual movement to whole theories to optimize transportation. From a visualization perspective the Space-Time-Cube was the most prominent element in Hagerstrand’s approach. In its basic appearance these images consist of a cube with on its base a representation of geography (along the x- and y-axis), while the cube’s height represents time (z-axis). A typical Space-Time-Cube could contain the space time-paths of for instance individuals or bus routes. However, when the concept was introduced the options to create the graphics were limited to manual methods and the user could only experience the single view created by the Draftsperson. An alternative view on the cube would mean to go through a laborious drawing exercise. Today’s software has options to automatically create the cube and its contents from a database. Data acquisition of space-time paths for both individuals and groups is also made easier using GPS. Today, the user’s viewing environment is, by default, interactive and allows one to view the cube from any direction. In this paper an extended interactive and dynamic visualization environment is proposed, and demonstrated, in which the user has full flexibility to view, manipulate and query the data in a Space-Time-Cube. Included are options to move slider planes along each of the axes to for instance select, or highlight a period in time or location in space. Examples will be discussed in which the time axis is manipulated by for instance changing world time for event time (time cartograms). Creativity should not stop here since it has been shown that especially an alternative perspective on the data will sparkle the mind with new ideas. The user should be allowed to for instance let the x- and/or y-axis be represented by other variables of the theme studied. Since the cube is seen as an integral part of a geovisualization environment the option to link other views with other graphic representation does exist.

  • Offsite construction skills evolution : an Australian case study
    'Emerald', 2021
    Co-Authors: Ginigaddara Buddhini, Perera Srinath, Feng Yingbin, Rahnamayiezekavat, Payam R.
    Abstract:

    Purpose – The construction industry is currently responding to pressures of industrialisation happening across all sectors. Consequently, offsite construction (OSC) has become a vehicle to achieve industrialisation. This requires changes in traditional construction processes resulting in possible changes in construction skill requirements. Accordingly, the purpose of this study is to identify and review prevailing OSC practices and skills in the Australian construction industry. This study aims to critically analyse the existing skill profile classifications through a single case study and identify the need for an OSC specific skill classification. Design/methodology/approach – This study follows a case study design, with an in-depth analysis of a single construction project. Only one case study was studied because scientifically, one example was enough to prove that the prevailing skill classifications do not represent OSC skills in a modern context. Data was retrospectively collected through semi-structured interviews of project stakeholders representing design, manufacture and assembly. Content analysis was conducted to analyse the collected data and produce findings. Findings – This study identifies the inadequacy of the existing classification system, unavailability and the need of OSC specific skill categorisation. It highlights new skills that enter OSC; building information modelling engineer, three-dimensional Draftsperson, OSC project manager and project coordinator, which are not identified in the available Australian skill classifications. These, together with existing skills need to be carved in to create a new skill classification. Originality/value – This study is the first of its kind where a comprehensive OSC project is evaluated as a case study to determine OSC skill classification requirements in Australia
