CONBPS : an expert system to improve the efficiency of the construction process

The aim of the research outlined in this paper is to develop a best practice process model for building projects based on the use of an expert system. The CONstruction Best Practice System (CONBPS) focusses on projects which are based on the traditional procurement strategy, using the JCT 80 standard form of contract. The model clearly identifies the sequence of construction activities. It also identifies the roles and responsibilities of the major parties on the building team and the issues within the project cycle, which can prove critical to project success. The system incorporates many user-friendly functions, including the provision of multi-choice icons and the provision of an on-line help function. Besides, it also provides interim and final reports which are used to advise the participants on the success factors that they have ignored and to which aspects they should pay more attention. A framework was initially developed focussing on the whole design process with a full knowledge-based system developed for the Inception Stage. CONBPS can be used as a teaching/learning tool to assist teachers and students to better understand the construction process. Also, it could prove useful to project managers and all the participants in the construction process.

Kids in design : designing creative schools with children

There is a consensus that children should be involved in the planning and design process of their schools, and attempts have been made throughout the world. This paper introduces a ‘Kids in Design’ project, through which primary school children worked with university architecture students to design a school playground. The aim of the project was to encourage the full potential of children’s creativity and generate creative school design outcomes. From October to December 2011, the ‘Kids in Design’ project was conducted in Roslyn Road Primary School (Geelong, Australia). Through eight weeks of workshops, children in Year 5 & 6 worked with architecture students from Deakin University (Geelong, Australia) to design a school playground. Assessing the design outcomes of this project, assertions are made that creative design outcomes have been achieved. Deakin University is currently working with another primary school to replicate the ‘Kids in Design’ project in 2012.

The Mallee Fire and Biodiversity Project

Fire is a widespread disturbance and an important ecological process in semi-arid mallee ecosystems of southern Australia. Understanding the effects of fire on plants and animals is a key challenge for the conservation and management of biodiversity in this ecosystem. Commenctngin2006, the Mallee Fire and Biodiversity Project is investigating the effects of fire on range of taxa (vascular plants, invertebrates, reptiles, birds and mammals), with a focus on the influence of the properties of 'fire mosaics' on biota. A 'whole of landscape' design was employed, in which the flora and fauna were sampled in 28 study landscapes, each4 km in diameter (12.5 km2) across a 104,000 km2 area of the Murray Mallee region of Victoria, SA and NSW. Here, we summarise some key results and outputs from this project to date. These include: detailed maps of fire history and major vegetation types; a method for predicting the age of mallee vegetation; novel information about the distribution of fire age-classes in the region; and changes to vegetation structure and in the occurrence of reptile, bird and mammal species over a century-long post-fire time-frame. We also present an overview of the effects of fire mosaics (extent of particular age classes, diversity of fire age-classes) on the richness of some mallee fauna. A wealth of knowledge has been developed through the Mallee Fire and Biodiversity Project that will assist the management of mallee ecosystems in southern Australia for the future.

Occupant behaviour simulation for cellular offices in early design stages - Architectural and modelling considerations

Building simulation is most useful and most difficult in early design stages. Most useful since the optimisation potential is large and most difficult because input data are often not available at the level of resolution required for simulation software. The aim of this paper is to addresses this difficulty, by analysing the predominantly qualitative information in early stages of an architectural design process in search for indicators towards quantitative simulation input. The discussion in this paper is focused on cellular offices. Parameters related to occupancy, the use of office equipment, night ventilation, the use of lights and blinds are reviewed based on simulation input requirements, architectural considerations in early design stages and occupant behaviour considerations in operational stages. A worst and ideal case scenario is suggested as a generic approach to model occupant behaviour in early design stages when more detailed information is not available. Without actually predicting specific occupant behaviour, this approach highlights the magnitude of impact that occupants can have on comfort and building energy performance and it matches the level of resolution of available architectural information in early design stages. This can be sufficient for building designers to compare the magnitude of impact of occupants with other parameters in order to inform design decisions. Potential indicators in early design stages towards the ideal or worst case scenario are discussed.

Business process affordances

 The bypassing of established business processes is a significant problem in organisations. This research proposes a novel framework for incorporating psychological and social factors into the business process design. The framework promises to increase system adoption and decrease process bypassing, ultimately making an organisation's work more effective and efficient.

An early-stage design decision-support tool for selecting building assemblies to minimise a building's life cycle energy demand

The significant effects of the building industry on the natural environment are well documented and improving the environmental performance of buildings is an on-going challenge. This is particularly the case for projects with restrictive budgets and timelines and because many existing environmental assessment tools are designed to be used too late in the design process. The use of tools during the early design stages may assist in achieving greater improvements in a building’s environmental performance. However, user-friendly tools with the ability to comprehensively compare environmental information between various building assemblies and materials, which can be easily adopted during the early design stages of a project, are not readily available. This paper presents the progress to date in developing a tool which supports building designers in identifying and selecting preferred building assemblies with the aim of minimising a building’s life cycle energy demand. The tool is based on comprehensive energy performance data for a broad range of building assemblies across all Australian climate zones. Allowing for adjustments to a set of pre-defined and user-defined assemblies the designer is able to see how assemblies perform in relation to each other. This provides valuable information to support decision-making relating to minimising the life cycle energy demand of buildings.

How technology shapes assessment design: findings from a study of university teachers

A wide range of technologies has been developed to enhance assessment, but adoption has been inconsistent. This is despite assessment being critical to student learning and certification. To understand why this is the case and how it can be addressed, we need to explore the perspectives of academics responsible for designing and implementing technology-supported assessment strategies. This paper reports on the experience of designing technology-supported assessment based on interviews with 33 Australian university teachers. The findings reveal the desire to achieve greater efficiencies and to be contemporary and innovative as key drivers of technology adoption for assessment. Participants sought to shape student behaviors through their designs and made adaptations in response to positive feedback and undesirable outcomes. Many designs required modification because of a lack of appropriate support, leading to compromise and, in some cases, abandonment. These findings highlight the challenges to effective technology-supported assessment design and demonstrate the difficulties university teachers face when attempting to negotiate mixed messages within institutions and the demands of design work. We use these findings to suggest opportunities to improve support by offering pedagogical guidance and technical help at critical stages of the design process and encouraging an iterative approach to design.

Recognizing appropriate representation of Indigenous knowledge in professional design practice

This paper focuses on the need for designers to follow clear, concise, workable practises to engage appropriately and ethically with indigenous knowledge on projects involving the graphical depiction of indigenous culture. Incorporating indigenous symbols into visual communication design strategies impacts a wide range of stakeholders and therefore requires a sensitive approach with broad consultation in regard to permissions and intellectual property rights; issues can be worked through if respectful practice methods are applied. This paper acknowledges cultural appropriation is not new and that creative, cross cultural interpretation and expressions of hybridity should be encouraged. However respectful communication, consultation, and collaboration are required whenever commercial application of indigenous culture is attempted. To demonstrate the need for clarity, three case study examples will be presented, each with design solutions involving the use of graphical depictions of indigenous culture and each selected due to the varying degrees of stakeholder engagement undertaken in the design process. The introduction of the ladder of stakeholder engagement theory is a new concept introduced in this paper that can be employed to better consider the appropriate and ethical engagement of designers with indigenous knowledge.

Nonlinear adaptive backstepping controller design for controlling bidirectional power flow of BESSs in DC microgrids

In this paper, a nonlinear adaptive backstepping controlleris designed to control the bidirectional power flow (charging/discharging) of battery energy storage systems (BESSs) in a DCmicrogrid under different operating conditions. The controller isdesigned in such a manner that the BESSs can store the excess energyfrom the renewable energy sources (RESs) in a DC microgrid aftersatisfying the load demand and also feeding back the stored energyto the load when RESs are not sufficient. The proposed controller isalso designed to maintain a constant voltage at the DC bus, whereall components of DC microgrids are connected, while controllingthe power flow of BESSs. This paper considers solar photovoltaic(PV) systems as the RES whereas a diesel generator equipped witha rectifier is used as a backup supply to maintain the continuity ofpower supply in the case of emergency situations. The controller isdesigned recursively based on the Lyapunov control theory whereall parameters within the model of BESSs are assumed to beunknown. These unknown parameters are then estimated throughthe adaptation laws and whose stability is ensured by formulatingsuitable control Lyapunov functions (CLFs) at different stages ofthe design process. Moreover, a scheme is also presented to monitorthe state of charge (SOC) of the BESS. Finally, the performanceof the proposed controller is verified on a test DC microgrid undervarious operating conditions. The proposed controller ensures the DCbus voltage regulation within the acceptable limits under differentoperating conditions.

Collaboration and student engagement in design education

One of the great paradoxes in design education is that undergraduate students are encouraged to study and model the behaviors and attitudes of famous designers, but without being aware that such esteemed individuals rarely work in isolation. The vast majority of designers work in teams, as part of both the conceptualization and production processes. Even 'design-auteurs' or 'artist-designers' must still interact with, respectively, clients, consultants and contractors, or patrons, curators and publishers. As a result of this, collaboration is widely considered an essential part of the design process and a critical skill for developing a career in the design industries. However, while design practitioners and the professional bodies that represent them acknowledge the importance of groups and teams, there has been a general reluctance (either an unwillingness or inability) to emphasize the importance or team processes, or em­bed the development of team skills, in undergraduate design curricula. There are many reasons for this situation existing, but we cannot underestimate the general attitude, implicit in much design education and promulgated through the design media, that creativity is an individual trait.

An evaluation of group work in first-year engineering design education

It is argued that ‘design' is an essential characteristic of engineering practice, and hence, an essential theme of engineering education. It is suggested that first-year design courses enhance commencing student motivation and retention, and introduce engineering application content and basic design experience early in the curriculum. The research literature indicates that engineering design practice is a deeply social process, with collaboration and group interactions required at almost every stage. This chapter documents the evaluation of the initial and subsequent second offerings of a first-year engineering design unit at Griffith University in Australia. The unit 1006ENG Design and Professional Skills aims to provide an introduction to engineering design and professional practice through a project-based approach to problem solving. The unit learning design incorporates student group work, and uses self-and-peer-assessment to incorporate aspects of the design process into the unit assessment and to provide a mechanism for individualization of student marks.

Learning in organizations : complexities and diversities

Learning in Organizations focuses on the issues of diversity in the context of organizational learning. It examines those diversities present in organizations among learners and contexts both within and between organizations. In order for learning to be effective and efficient these diversities must be acknowledged and addressed in the learning design process.

Innovation in construction : experiences from a hypocaust system in Australia

Introducing new technologies poses a particular challenge to the players involved in a project. For a successful low energy building, a new design process is required and players must assume new and additional responsibilities. Hypocaust systems, where conditioned or non-conditioned air is passed through ducts within the concrete floor or ceiling of a building prior to its delivery to the rooms, are starting to appear in new buildings in Australia. This paper describes the lessons learned from the early experiences with a hypocaust system, installed in a new building in Melbourne. It concludes that a more cooperative process among all those involved in introducing and using a new 'technology' is essential if the problems described are to be avoided or at least minimized.
