Abstract

Purpose

A key factor adversely affecting contractor social networking performance is the improper handling and information management of contractor’s services delivery on websites. Contractor social networking is particularly problematic on industrialised building system (IBS) infrastructure maintenance projects where contractor’s certified quality product and firms are not matched with maintenance specialisation services. The paper aims to discuss this issue.

Design/methodology/approach

This paper reports on the early stages of research which is developing a new information and communications technology (ICT)-based approach to managing contractor social networking on IBS infrastructure maintenance schemes. As a precursor to this work, the paper reviews current contractor social networking websites practices on IBS infrastructure maintenance projects and explores the ICT tools and techniques currently being employed on such projects.

Findings

The findings reveal the need for more sophisticated contractor social networking websites solutions which accord with the needs of IBS infrastructure maintenance schemes.

Originality/value

The paper concludes by presenting a research framework for developing such a system in the future.

Abstract

Purpose

Maintenance management is a core process in infrastructure asset management. Infrastructure organisations must constantly strive to ensure the effectiveness of this process in order to obtain the greatest lifetime value from their infrastructure assets. This paper aims to investigate how infrastructure organisations can enhance the effectiveness of their maintenance management process.

Design/methodology/approach

This study utilised multiple case studies as the research approach. The case organisations were asked to identify the challenges faced in the maintenance process and the approaches they have adopted to overcome these challenges. Analysis of these findings, together with deductive reasoning, leads to the development of the proposed capability needed for effective maintenance management process.

Findings

The case studies reveal that maintenance management is a core process in ensuring that infrastructure assets are optimally and functionally available to support business operations. However, the main challenge is the lack of skilled and experienced personnel to understand and anticipate maintenance requirement. A second challenge is the reduced window of time available to carry out inspection and maintenance works. To overcome these challenges, the case organisations have invested in technologies. However, technologies available to facilitate this process are complex and constantly changing. Consequently, there is a need for infrastructure organisations to develop their technology absorptive capability, i.e. the ability to embrace and capitalise on new technologies to enhance their maintenance management process.

Originality/value

The paper provides an in‐depth analysis of three case studies that reveal that an infrastructure organisation cannot avoid the need to introduce technologies to monitor the condition of its assets and to predict when assets will fail. It suggests that organisations must be proactive in searching for the best technologies for their purpose.

Abstract

Purpose

The main purpose of this paper is to develop an approach to analyzing the factors influencing the performance of railway infrastructure, to propose an approach to measuring the overall railway infrastructure effectiveness (ORIE), and to test these approaches in a case study to verify their effectiveness.

Design/methodology/approach

The methodology adopted here was to develop a concept for measurement of the overall effectiveness of a railway infrastructure similar to that for measurement of the OEE. The concept thus developed was applied on Swedish railway track sections for collecting data and for their ORIE validation, as a case study.

Findings

The findings of the ORIE case study show that the model can be used for other sections of the Swedish railways. It can also be applied to other railways with some modifications.

Practical implications

ORIE can measure the extent to which the railway infrastructure system manages to deliver its agreed performance to the traffic operators. Infrastructure managers can also use the ORIE as a key performance indicator, which can provide important input for effective decision making.

Originality/value

The paper presents a structured way of developing a conceptual ORIE model applied to the railway‐sector. This model can be used by other railways with suitable modifications.

The purpose of the paper is to analyze the relationship between maintenance of existent and investment in new infrastructure in Norwegian local governments.

Abstract

Purpose

The purpose of the paper is to analyze the relationship between maintenance of existent and investment in new infrastructure in Norwegian local governments.

Design/methodology/approach

A reduced form vector autoregressive system is estimated using a 29-year-long panel data set for the Norwegian local governments.

Findings

The data reveal that increased investment in new infrastructure sparks little, if any, increase in maintenance. The results also indicate that increased maintenance expenditures spark new investments. Because more investments mean more infrastructure and adequate maintenance should give that investments are not caused by maintenance, the results suggest that the local governments have not optimized their maintenance scheduling in this period.

Originality/value

Even though maintenance and investment are large expenditures that both serve as inputs to the stock of infrastructure, little is known about the relationship between the two. The findings in this paper suggests that Norwegian local governments have not planned their maintenance and investments well in the past, and this can be part of the explanation as to why local public infrastructure in Norway is presently in poor condition.

Abstract

Purpose

The purpose of this paper is to establish whether this type of approach is suitable for maintenance schemes from the perspective of both the public agent and the service provider. Until recently, non‐privately funded public‐private partnerships have been adopted for the maintenance of infrastructure facilities.

Design/methodology/approach

In this study, stakeholders involved in a trial of a non‐privately funded public‐private partnerships project were invited to express their opinions on the success and pitfalls of this type of scheme. Semi‐structured interviews were carried out with 12 management and front‐line staff of the public and private partners to capture their opinions on the project. A questionnaire survey was also conducted to uncover the views and standpoints of other stakeholders on PPP. A total of 33 respondents completed the questionnaire.

Findings

The results indicate that the non‐privately funded PPP approach is more cost‐effective and efficient in the delivery of maintenance services when compared with the traditional term contract. The performance‐based payment mechanism adopted could help improve the quality of maintenance services performed by the contractor. The inspection and programming tasks are transferred to the service provider relieving the workload of the public agency. Most stakeholders who participated in this study agreed that the non‐privately funded PPP approach can allow higher flexibility, encourage innovation, enhance cost‐effectiveness and improve the efficiency of work when compared with the traditional term contract in the delivery of maintenance services.

Originality/value

This paper provides a general introduction to the method adopted in the non‐privately funded public‐private partnerships approach with particular reference to the maintenance of infrastructure schemes. More important, the potentials and pitfalls of using this type of mechanism with maintenance projects are examined, which helps enhance understanding of this rather unexplored topic.

The purpose of this paper is to describe an application of an effective risk-based methodology to support a living maintenance programme for railway infrastructure.

Abstract

Purpose

The purpose of this paper is to describe an application of an effective risk-based methodology to support a living maintenance programme for railway infrastructure.

Design/methodology/approach

The overall research strategy is a single case study of switches and crossings at the Iron Ore Line in northern Sweden. The analysis was performed as a risk workshop guided by a methodology that integrates reliability-centred maintenance and barrier analysis.

Findings

The applied methodology is valuable to systematise and improve the existing maintenance programme, as well as supporting a continued living maintenance programme.

Research limitations/implications

The single case study approach may decrease the validity of the achieved results. However, similar case studies corroborate the results, which affect the validity in a positive way.

Practical implications

The resulting maintenance programme is effective, through compliance with external requirements, and more efficient, through improvements of tasks and intervals.

Social implications

An enhanced railway infrastructure maintenance programme contributes to improved safety, punctuality, and costs. Hence, railway becomes a more attractive mode of transport. Thereby, it also supports a safety performance of the railway that society is willing to pay for.

Originality/value

Significant improvements of the maintenance programme are achieved through adjustment of inspection intervals and tasks. The results also support the development of indicators, monitoring, and continuous improvement.

Abstract

Purpose

The purpose of this paper is to present a methodology to evaluate the capital investments in infrastructure projects managed by private operators considering uncertainties in the operation and maintenance of the infrastructure components.

Design/methodology/approach

The methodology described in this paper is based on two major sources of information: deterioration curves of the infrastructure systems obtained from Markov chain models and the value of flexibility obtained from a real options analysis.

Findings

Using this methodology, it is possible to determine whether there is value if project managers adopt flexible strategies in determining capital investments. These strategies refer to the opportunities of postponing, deferring or canceling capital investments required to maintain the operation of the infrastructure systems.

Research limitations/implications

The model utilizes Monte Carlo simulation and real options analysis to overcome the complexities associated with the solution of the differential equations that represent the variability of the main factors in the project cash flow.

Originality/value

The methodology presented in this paper can be used by public officials, private investors, and asset managers to determine the value of flexibility associated with the strategies required to maintain the operation of infrastructure assets.

Abstract

Purpose

Switches and crossings (S&Cs) are an important component of Banverket's (the Swedish National Rail Administration's) infrastructure and are associated with 13 per cent of the total maintenance cost. Therefore, it is important that a detailed study of different aspects of the costs of S&Cs should be undertaken to analyze individual maintenance costs. This will in the future give the possibility of enhancing the management of infrastructure.

Design/methodology/approach

A case study is undertaken to study, identify and classify the costs of S&Cs for Banverket. Data are taken from Banverket's maintenance information systems and accounting system.

Findings

A rough estimation of the cost for individual S&Cs can be identified in this way. The cost varies very much and a more detailed study is needed to validate the cost on this level. The average cost of a group of S&Cs varies less and is therefore more likely to reflect the true cost. The cost varies depending on the amount and type of traffic. Moreover, the type of S&C seems to reflect the cost variation, but further investigation is needed to verify this conclusion.

Research limitations/implications

The accounting system does not store data for individual assets, and further research would be more fruitful if individual costs could be recorded by the entrepreneur. Larger repairs should be separated from annual maintenance tasks in a future study. Data from this study could be used to build a life cycle cost model for S&Cs.

Practical implications

Cost identification is a first step in finding a way to organize maintenance in a more cost‐effective way.

Originality/value

The paper shows a way to distribute costs (in the accounting system) down to individual subsystems of the infrastructure. This enables analysts to find cost drivers and plan for modification of or reinvestment in the asset.

Abstract

Purpose

The purpose of this paper is to provide an understanding on the impact of quality management (QM) tools and techniques in water supply infrastructure maintenance and the generation of non-revenue water (NRW) by Namibian Municipal Water Distributors.

Design/methodology/approach

In-depth interviews were selected as the primary data collection method, while secondary data were collected using document review and observations. In-depth interviews as primary method provided rich data and details on the subject matter from the respondents. Document review and observations provided a holistic perspective and understanding of the context within which the maintenance projects are handled by municipal water distributors.

Findings

The study found that as the number of QM tools employed to analyze maintenance data increases, the generation of NRW by the municipality decreases. However, for the tools to be effective, they should cover applications such as problem identification, data analysis, process analysis, decision making, planning, quality control and statistical process control, this helped Namibian municipalities to produce low volumes of NRW. In contrast, municipalities using QM tools arbitrarily lead to high quantities of NRW generation.

Originality/value

The World Bank recommends that NRW should be less than 25 percent of the total water produced, while in many countries NRW is up to 60 percent. Developed economies have made efforts to reduce NRW but efforts are still at nascent stage in emerging economies. This is the first study providing evidences of QM tools application in maintenance process and effect on NRW.
