ItemEngaging employees with good sustainability: Key performance indicators for dry ports(MDPI AG, 2019-05-24)Dry ports have the potential to enhance the sustainability of transport systems, yet their introduction requires major changes to the current logistics chain. Further, emphasising sustainability goals and continued employee engagement can be a challenge when developing or implementing organisational change management programs in dry ports. Key considerations include governmental requirements and compliance, investor expectations, as well as employee engagement; these factors may be conflicting. The top-down management approach supported by strong leadership, participative approaches and constant communication assists in achieving successful change management. Sound selection of key performance indicators (KPIs) provides a set of metrics to track and aid the change process. They serve as a unifying link between top managements’ sustainability goals and employees’ engagement. The initial findings of our research confirm that both port and terminal operators have a gap in their understanding of the importance of sustainability goals and environmental goals. This will have a flow-on effect of port and terminal operators not driving the right messages to their staff in their organisational change management programs. Based on a critical literature review, it has been established what might qualify as good sustainability KPIs for dry ports. An example of a dry port at the Port of Somerton has been included. As every dry port has different requirements and constraints, it is important to develop KPIs together with stakeholders.

ItemEducation & training for zero energy and lean manufacturing & construction of housing in Australia(Curtin University, 2018-09-27)For zero energy and efficient production of mass customised housing, good outcomes are possible only when it is supportedby a good education curriculum and infrastructure. This paper reports on the status of education for zero energy and lean manufacturing and construction of houses in Australia by investigating offerings of Victorian schools, vocational training and highereducation sectors in these respects. The courses currently offered within Australian Qualifications Framework (AQF) were assessed. It was found that there are still gaps in the education infrastructure that do not provide fully for opportunities to educate the workforce in these areas. Although the main knowledge areas of zero energy are sufficiently covered by courses involving sustainability, renewable energy, energy efficiency in buildings and infrastructure construction, the teaching of lean concepts are not widespread in all these education sectors in Australia.

ItemOccupational stress and workplace design(MDPI AG, 2018-09-23)The World Green Building Council (WGBC) advocates improvements in employee health, wellbeing, and productivity in buildings as people are about 90% of an organisation’s expense and well exceed building costs and energy costs. It was reported that earlier research on workplace design primarily focused on physical arrangement of employees’ immediate work area, and ambient environmental qualities of the work area. Building organisation, exterior amenities, and site-planning have been given less attention. Therefore, we examine more closely the health relevance of both proximal and remote aspects of workplace design. Occupational stress is a complex phenomenon that is dynamic and evolving over time. This investigation reviews the existing fundamental conceptual models of occupational stress, workplace design, and connection to nature. It aims to develop an improved model relevant to work place design and occupational stress linked with connection to nature. The proposed improved model is presented with an appropriate causal loop diagram to assist in visualizing how different variables in a system are interrelated. The developed model highlights how connection to nature in workspaces can function as a work resource with a dual effect of improving physical wellbeing and psychological wellbeing.

ItemA minimum viable product design of volumetric building modules(ZEMCH Network, 2018)This paper explores the adaptation of an IBM approach to product development emphasising user experience and critical requirements. The potential of this approach to be applied to offsite building manufacture is identified. Minimum Viable Product (MVP) has helped IBM validate key hypothesis about a product, thus increasing its probability of success, before completing its development. This paper attempts to answer the question of whether an MVP of manufactured building unit can aid cost awareness at early design phase of building and also facilitate a mass customisation. Since about 80% of a building’s cost is determined in the concept design phase and the frontend design of manufactured buildings is seemingly unaware of costs, time and processes associated with the methods, this can cause unnecessary cost increases. The investigation involves the design of a parametrically constrained building system of an MVP of space requirement to program. The Victorian apartment design standards, logistic constraints, and user customisation to room sizes are considered to define spatial limitations in the case study. The effectiveness of the system is examined through a case study analysis to identify the possibility for variation of volumetric unit in an apartment building scenario. It is expected to develop a new understanding of modular building constraints at early design stage yet still allow for a mass customized outcome without the expense of variation through lack of front end knowledge of the manufactured system. It is also expected to produce a better understanding of base building costs and time associated with a mass customisable manufactured building system, suggesting possible cost data inputs to the system. It is anticipated that an MVP approach to early building design can help determine design and cost viability of building projects to stakeholders in the early design phase.

ItemMoving assembly line for low cost mass customised homes(ZEMCH Network, 2018)This paper explores the potential for a mass customised building volume applying lean based moving assembly line method. Past experience would suggest that the moving assembly line stems from a mass production, that reduces customisation through standardisation of processes. However, when combined with a seamless method of design to documentation up front, it is proposed that the moving assembly line could allow for mass customisation. In addition, lean practices suggest that refinements of processes are intrinsically linked to a repetitious assembly process used in producing a homogenous object. We seek to break these moulds and examine the potential for a lean moving assembly line to allow mass customisation and what is required to do so. Moving assembly line offsite building manufacture factories in Australia, Sweden and Japan were visited and observed. A comparative exercise of when, what happens where was undertaken to identify the approaches. It was found that the moving assembly line allows cost and time savings in off-site manufacture of multi storey buildings, and could enable for a mass customised outcome. Lean is the facilitator, or enabler of this process working efficiently.
