The purpose of this paper is to investigate the level of discrepancy in the valuation process adopted by valuers in the study area with a view to provide solution.

The study is based on both structured questionnaire and content analysis of valuation reports. In total, 185 (41 percent) structured questionnaires were randomly distributed to practicing estate surveying firms; out of 450 firms in Lagos, 173 were retrieved and used for analysis. However, the content analysis was based on 54 valuation reports on plants and equipment to investigate the extent of compliance to valuation process, standard and best practices among practitioners.

The findings from the study show that most of the practitioners lack the expertise to carry out plant and machinery (P&M) valuation, and there is evidence of poor application of methodology and lack of adherence to standards.

The findings from this study will reinforce the need for specialization and enforcement of standard in plant and equipment valuation practice, which will enthrone consistency, uniformity and reliability.

This study is the first to deal with methodology lapses in plant and equipment valuation in the study area. Ashaolu (2016) worked on the inter-disciplinary nature of plant and equipment valuation, whereas Otegbulu and Babawale (2011) worked on valuer’s perception or potential sources of inaccuracy in P&M valuation in Nigeria.

The purpose of this paper is to focus on households' willingness to pay for electricity consumption and mitigation expenditure due to poor electricity infrastructure as a measure of demand and tariff setting.

In this paper, the demand side management (DSM) approach was adopted in establishing user demand for electricity in the study area.

Based on the high cost (averting expenditure) of providing alternative power supply, households are willing to pay extra for more reliable and regular power supply.

The study is a deviation from the usual command or supply side management approach to infrastructure provision and management.

There is limited research on DSM approach to electricity infrastructure provision in Nigeria. The study will enhance the chances of cost recovery under private‐public partnership arrangement. The paper identifies that a reliable and reasonable priced electricity supply is essential for a developing country.

From the perspective of plant and machinery valuation, this paper aims to assess the factors that constrain accuracy in plant and machinery valuation in the Nigerian context.

This paper is based on the technical, economic and market infrastructure affecting machinery and equipment valuation in Nigeria and surveyed 150 practicing firms in Lagos to elicit from them what they believe are the major constraints to valuation accuracy.

The findings reveal that, due to lack of specialization in machinery and equipment valuation, very few valuers have sufficient knowledge content to engage in the exercise. Four significant factors are established to be contributing most to valuation inaccuracy.

This study is the first on inaccuracy in machinery and equipment valuation, and consequently highlights the need to equip Nigerian valuers to face the challenges of the expertise required in this specialized area of valuation.

This paper aims to determine the sustainability of housing development in the context of neighbourhood infrastructure provision and also to examine the level of averting cost and substitutes resorted to by households in the study areas.

A total of 80 questionnaires each were distributed and retrieved from households in Festival of Arts and Culture (FESTAC) town and Badia, Lagos, Nigeria. The questionnaire design was based on a combination of an extensive review of literature dealing with the economic impact of urban infrastructure on the citizens of Lagos metropolis. All respondents returned completed questionnaires in a usable format, representing a 100 per cent response rate.

Infrastructure provision is not sustainable in the study areas. This is based on the fact that infrastructure provision in the study areas is deplorable and in consequence households are willing to pay for its improvement.

Sustainability is a goal that allows for continuing improvement of standards of living without irreversible damage to resources need to survive as that humans species. It therefore implies that housing development has to be designed in a sustainable manner with due regard to its neighbourhood. This is reinforced by the fact that housing development cannot be sustainable without neighbourhood interactions and cost‐efficient infrastructure management.

Review of sustainable urban services is needed to curb slum formation and deteriorating housing conditions in urban neighbourhoods. This will be a veritable tool in urban housing and infrastructure management.

Climate adaptation, energy efficiency, sustainable development and green growth are societal challenges for which the Facilities Management (FM) profession can develop solutions and make positive contributions on the organisational level and with societal-level effects. To base the emerging sub-discipline of sustainable facilities management (SFM) on research, an overview of current studies is needed. The purpose of this literature review is to provide exactly this overview.

This article identifies and examines current research studies on SFM through a comprehensive and systematic literature review. The literature review included screening of 85 identified scientific journals and almost 20,000 articles from the period of 2007-2012. Of the articles reviewed, 151 were identified as key articles and categorised according to topic.

The literature review indicated that the current research varies in focus, methodology and application of theory, and it was concluded that the current research primary addresses environmental sustainability, whereas the current research which takes an integrated strategic approach to SFM is limited. The article includes lists of reviewed journals and articles to support the further development of SFM in research and practice.

The literature review includes literature from 2007 to 2012, to manage the analytical process within the project period. However, with the current categorisation and the access to the reviewed journals and articles, it is possible to continue with the latest literature.

The article provides an overview of theoretical and practical knowledge which can guide: how to document and measure the performance of building operations in terms of environmental, social and economical impacts? How to improve the sustainability performance of buildings? What are the potentials for and barriers to integrating sustainability into FM on strategic, tactical and operational levels?

The paper presents the most comprehensive literature study on SFM so far, and represents an important knowledge basis which is likely to become a key reference point for pioneers and scholars in the emerging sub-discipline of SFM.
