Even though there is a large body of knowledge related to buildings, only a limited number of examples with a focus on asset management exist in published literature. More importantly, current literature lacks rating systems that support tactical and operational management of building infrastructure. This paper addresses the aforementioned knowledge gap and building industry requirement by proposing an index for operational management of a public building using building level of service (LOS). In the context of buildings, LOS is defined as an assessment of the operational performance provided to building users, society, and the environment. A fuzzy synthetic evaluation (FSE)-based method was used to assess the LOS of buildings. First, key performance categories and indicators were defined for operating building performance assessment. Indicators and benchmarks were customized for an aquatic centre building. A case study was conducted to demonstrate the application of the LOS index. Results from this approach provides an assessment of the operational performance of the aquatic centre building with respect to nine LOS performance categories. Overall building LOS was evaluated as good for the three pseudo scenarios considered. The proposed LOS index facilitates asset management of public buildings by providing information for operational, tactical, and strategic decision making.

“…Whereas the Khatri et al (2011) conceptual model divided the technical dimension, to reflect service effectiveness and service reliability separately. Although these are interconnected IWRM issues, the separation of the social and technical dimensions better fitted the four IWRM dimensions 50 outlined in the research problem in Chapter 1.…”

“…Although these are interconnected IWRM issues, the separation of the social and technical dimensions better fitted the four IWRM dimensions 50 outlined in the research problem in Chapter 1. Another difference in the Khatri et al (2011) model was the way this model further subdivided the economic dimension into costs and prices. Both costs and prices were dealt with under the economic dimension of the new IWRM conceptual model in this study.…”

“…The IWRM model developed an integrated approach to examining the four dimensions of the IWRM problem -environment, policy, society and economy. The model was based on the integrated total water cycle rather than the natural water cycle used in existing IWRM models (Carden & Armitage 2012;Khatri et al 2011;Ross et al 2006;Koudstaal et al 1992). …”

Further closing the integrated total water cycle in the Lockyer Valley: a catchment scale integrated water resource management conceptual model

There is a need to facilitate decision making on integrated water resource management (IWRM) issues, minimise leakages from and further close the integrated total water cycle (ITWC). The complex social, economic and environmental dimensions and the scarcity of the resource make water management one of the truly "wicked" environmental management problems (cf. Rittel & Webber 1973). This study seeks to contribute to the resolution of this IWRM problem by adding a new definition of IWRM and providing analytical tools for the assessment of water catchments issues, conditions and improving management. A multidisciplinary integrated approach assisted in understanding and managing the complex This study advances water management using an IWRM conceptual approach that further closes the ITWC by focusing on urban-rural IWRM opportunities, going beyond using recycled water for irrigation. This model differs from previous models as it focuses on the ITWC rather than the natural water cycle. The limits of the environment are a feature of this approach, along with recognition of the role of social capital, policy input from government and nongovernment sectors, ecological economic theory and principles, and hydrogeological modelling for a catchment scale conceptual IWRM model, thus setting it apart from previous models in literature. These additions bring a wider perspective to IWRM decision making and assist in the management of ongoing issues of changes in climate, growing demand for irrigation water, population growth, environmental demand for water and excess wastewater.Such issues affect IWRM worldwide.

Health, safety, and economic prosperity of the citizens of any country are ensured with services provided by core public infrastructures such as water, roads, transit, bridges, and wastewater. The water infrastructures are linear systems, among the most important and expensive municipal infrastructure assets. Maintaining integrity and reliability of water infrastructures is the primary goal of water utilities, governmental agencies, and other stakeholders. It has been quite challenging to maintain the integrity and reliability of water infrastructures because of the aging, aggressive environmental factors, climate change, improper maintenance and renewal, and resource shortages. In this article, the asset management framework for the water infrastructures has been discussed. The main objective of the asset management framework is to provide a desired level of service at a minimum cost. The asset management framework will provide the water utility with the capacity to make informed decisions based on the current and anticipated future performance of the asset. This framework will also help the water utility to improve strategic, tactical, and operational planning‐level decisions considering different dimensions of analysis such as performance, risk, and cost analysis.
