Maintenance is undergoing a major revolution. The management of maintenance is being impacted by business-driven changes that are forcing fundamental improvements to the maintenance function. Maintenance planning and execution are now considered as a strategic component of asset life cycle management. The link between maintenance and design is being furthered by placing emphasis on considering reliability and maintainability during the design phase. The application of Reliability-Centered Maintenance is becoming an important method for determining the optimum maintenance program for facility assets, while at the same time providing a solid foundation for triggering selective system improvements and design changes and managing life cycle cost and risk associated with assets. The concept of dependability provides the focus for integrating design, operations and maintenance into a coherent and complete life cycle approach to facilities. Dependability is strongly linked to quality standards since, for many companies, dependability is the major component of quality that has to be satisfied to meet customer needs. This paper describes the practical application of a quality approach to a gas transmission company which has recently undergone a reengineering of its design, operations and maintenance processes.

Multidisciplinary Perspective

Effective management of physical assets should deliver maximum business value. Therefore, Asset Management standards such as PAS 55 and ISO 55000 ask for a life cycle approach. However, most existing methods focus only on the short term of the asset's life or the estimation of its remaining life. These methods do not consider alignment to changing corporate objectives in a variable context, nor do they adopt a multidisciplinary perspective. This chapter argues that, to create maximum value, Asset Management should be a multidisciplinary and strategic practice that considers the complete life cycle of the asset: Asset Life Cycle Management. A practical twelve-step approach is presented to develop an Asset Life Cycle Plan (ALCP) in which expert sessions are used to identify the main lifetime impacts that influence the creation of business value from the use of the asset. The steps are illustrated with an example from practice. The chapter concludes that the ALCP supports asset managers in making long-term strategic decisions in a timely and effective manner.

Vertical Greening

Urban greening provides a wide range of ecosystem services to address the main challenges of urban areas, e.g., carbon sequestration, evapotranspiration and shade, thermal insulation, and pollution control. This study evaluates the environmental sustainability of a vertical greening system (VGS) built in 2014 in Italy, for which extensive monitoring activities were implemented. The life-cycle assessment methodology was applied to quantify the water–energy–climate nexus of the VGS for 1 m2 of the building’s wall surface. Six different scenarios were modelled according to three different end-of-life scenarios and two different useful lifetime scenarios (10 and 25 years). The environmental impact of global-warming potential and generated energy consumption during the use phase in the VGS scenarios were reduced by 56% in relation to the baseline scenario (wall without VGS), and showed improved environmental performance throughout the complete life cycle. However, the water-scarcity index (WSI) of the VGS scenarios increased by 42%. This study confirms that the installation of VGSs offers a relevant environmental benefit in terms of greenhouse-gas emissions and energy consumption; however, increased water consumption in the use phase may limit the large-scale application of VGSs.

Long Run

Maintenance, especially in a Marine environment, is continuous and costly. Life Cycle Management of a Marine Gas Turbine system encompasses many costs, of which repair parts, labor and equipment downtime associated with failures and maintenance are a significant portion. In fact, people (labor) make up the largest component of overall maintenance costs. Investing in people the largest cost driver to life cycle cost has a direct return in the long run, in terms of maintenance effectiveness and efficiencies. Applying and reinforcing knowledge and skills in a maintenance environment translates to improved reliability outcomes, longer operating time, fewer parts needs, and ultimately costs savings. However, given today’s constrained fiscal environment, the value of spending money for training rather than buying more parts or applying more maintenance, may not appear obvious. Such thinking is short sighted, and ultimately leads to reduced reliability and increased maintenance in the long run. This paper will explore these areas, and recommend how training programs can be effective predictive, proactive and responsive.

Reduction of human error can have a significant impact on the potential for spills and leaks and translate into better safety performance and financial gains for an organization. As important as the technical components of a design, construction, operation, and maintenance program is the human component of the activities being performed. In the Pipeline Industry, human factors can create the potential for a human error at many points along the life cycle of a pipeline. Using a life cycle approach to manage human factors can provide an organization the capability to integrate human factors into programs, standards, procedures and processes using a disciplined approach. This paper reviews the life cycle of a pipeline and identifies areas where the potential for human error can have catastrophic results. Guidance is provided on the development of a human factors life cycle for the organization and illustrates available industry resources as well as opportunities for further research and development.

Content Type

Purpose The purpose of this paper is to identify enablers for setting up relationally integrated value networks (RIVANS) for total facilities management (TFM) as a holistic approach to bridge the Project Management (PM) phase to the facilities management (FM) phase, aiming for better service delivery while optimizing the life-cycle cost. These enablers are proposed as required driving forces for the industry to bridge current gaps through RIVANS for TFM so as to improve the value of the facility and deliver better value to its stakeholders over its life span. Design/methodology/approach A literature review elicited 11 typical better values that could be achieved by suitably linking the PM and FM supply chains in general. While these were tested in parallel research exercises in Hong Kong, the UK and Singapore, this paper reports on the specific findings from Sri Lanka, where a Web-based questionnaire survey was conducted to identify potential better values for proposed relational networks (including the clients, consultants, contractors and suppliers in the supply chain). Better values were then clustered under principal domains/components using factor analysis to establish synergetic enablers. Findings In total, 11 significant better values for TFM were identified and four enablers were extracted as building long-term integrated networks, establishing a common resource pool linking PM and FM, enhancing sustainability of TFM and developing a similar protocol between PM and FM. Originality/value The study carried out in this paper contributes to knowledge by identifying drivers to bridge the gap between PM and FM to best achieve clients’ long-term aspirations through a holistic life-cycle approach. Furthermore, all stakeholders in TFM can revisit their practices to establish and strengthen the identified enablers.

Ageing, life cycle management and collective labour agreements Ageing, life cycle management and collective labour agreements Solutions for issues with respect to ageing are often searched for in Collective Labour Agreements (CLA). This article investigates the necessary conditions for concluding arrangements for ageing in a CLA. First the influence of government on the degrees of freedom of social partners is explored from the viewpoint of institutional economics. Next, the theoretical conditions are mapped that negotiating parties in companies can develop themselves, from the perspective of transaction costs, agency or stewardship. The various approaches are illustrated with some facts about Dutch CLAs. It appears that the management of individual life cycles is more appropriate as a concept than the issue of ageing. In a survey of 564 Dutch CLAs the aspects of a life cycle approach are listed. In the discussion the limitations of the present analysis are reviewed, the conditions are summarized, possibilities for further research are indicated. The conclusion is that under certain conditions the CLA can contribute to the management of one’s life course.

In a previous study, we analyzed the life cycle cost impacts of component location changes as applied to rolling stock products [1]. Here, we present the results of an analysis that quantifies the costs of changing heavy-duty connection locations in modular fabrication designs. Modules that are fitted together usually include multiple lines of piping, cabling, and other connections, which can be problematic when the design may change due to out-of-tolerance dimensions or design requirements that change prior to installation. Also, design changes after site delivery may require frequent location changes for components that are mounted within modules. Inflexible connections internal to the module or chassis may hinder module-to-module connections in the field, where changes are difficult, hot work is dangerous, and quality of repair is dubious. The aim of this analysis was to evaluate the costs to change various types of pipe connections between modules and the costs to change component locations within modules. In addition to allowing mounting locations to be easily changed between and within modules, adjustable connection points enhance the modularization and customization of products at the lower levels of production associated with the energy, shipbuilding and rolling stock industries.
