The field of environmental restoration is unique and highly complex. The purchasing function will be responsible for acquiring the restoration services for much of America′s estimated $500 billion clean‐up. Examines the specific characteristics of these projects and discusses how the unique nature of the work affects the function performed by today′s purchasing professionals. The scope and complexity of the purchasing job is vastly increased, requiring extensive teamwork and the development of dynamic and flexible purchasing strategies to handle the increased complexity and uncertainty at contaminated sites. Examines several alternative strategies for purchasing restoration services. No one strategy will fit every restoration project. The specific characteristics and unique nature of each project, and their effects on the purchasing job, must be considered in order to develop a well co‐ordinated and innovative purchasing strategy.

The purpose of this study was to investigate the stability of the cost performance index (CPI) for environmental remediation projects as the topic is not addressed in the literature. CPI is defined as the earned value of work performed divided by the actual cost of the work, and CPI stability represents the point in time in a project after which the CPI varies by less than 20 percent (measured in different ways).

After collecting monthly earned value management (EVM) data for 136 environmental remediation projects from a United States federal agency in fiscal years 2012 and 2013, the authors used the nonparametric Wilcoxon signed-rank test to analyze CPI stability. The authors also used nonparametric statistical comparisons to identify any significant relationships between CPI stability and independent variables representing project and contract characteristics.

The CPI for environmental projects did not stabilize until the projects were 41 percent complete with respect to project duration. The most significant factors contributing to CPI stability were categorized into the following managerial insights: contractor qualifications, communication, stakeholder engagement, contracting strategy, competition, EVM factors, and macro project factors.

As CPI stability for environmental remediation projects has not been reported in the literature, this research provides new insights to help project managers understand when the CPIs of environmental remediation projects stabilize and which factors have the most impact on CPI stability.

Environmental impact assessment (EIA) is one of the best approaches to identifying, preventing, minimising, compensating for any unfavourable impacts on the environment and also encouraging sustainability. This paper aims to investigate the barriers to EIA implementation for construction projects in Nigeria.

The study adopted a survey research technique. The snowball sampling approach was adopted to identify key stakeholders in EIA practice for the administration of questionnaire. A total of 187 questionnaires were administered and a response rate of 60% (113 questionnaires were adequately filled and returned) was achieved. Descriptive and inferential statistics were utilised in analysing elicited data.

The results from data analysis showed that, “failure to influence the decision-making process/multiple conflicting decision-making”, “unstable regulatory regime”, “lack of available, accessible and fit-for purpose data”, “inadequate public knowledge of legal issues” and “poor provision of information” were the top most five barriers to EIA implementation for construction projects in Nigeria. Also, the results from the research show a statistically significant degree of agreement on the rankings by the groups of key stakeholders in EIA concerning the barriers to EIA implementation for construction projects.

This paper contributed to more effective EIA studies by drawing attentions to barriers to EIA implementation for construction projects. An understanding of these barriers can help key stakeholders in the construction industry of developing countries such as Nigeria to facilitate development of methods required in reducing barriers to EIA implementation in the construction sector.

The purpose of this paper is to assess the vulnerability of the Kesennuma area in Japan to a tsunami disaster and to map the area of inundation.

Digital elevation model (DEM) data and ALOS image were used to create maps of the parameters of this study area: elevation, slope, coastal proximity, river, and land use. An analytical hierarchy process was used to assign weights to each parameter and a spatial multi-criteria analysis was applied through cell-based modelling for vulnerability mapping.

The vulnerability map shows that 17.679 km2 of the area could be inundated by a tsunami. High vulnerability areas were mostly found in coastal areas with a sloping coast and a cape area. A low elevation and the presence of rivers or water channels are factors that increase the impact of tsunamis. Inundation areas were predicted to spread in areas identified as having either high vulnerability or slightly high vulnerability.

Because of the limited geospatial data, the authors encourage further studies using DEM data with a high spatial resolution.

The results of this research can be used as basic information for disaster mitigation and urban planning in coastal areas.

This research creates a new approach for assessing which areas could be inundated by tsunamis, based on the vulnerability map generated through remote sensing and spatial multi-criteria analysis. Moreover, the parameters used are very close to those of actual inundation maps.

The purpose of the project was to investigate environmental law issues surrounding the regeneration of brownfield land.

Following a literature review, an inductive approach and an interpretivist epistemology with a phenomenological focus were chosen. A constructionist ontological stance was adopted. A qualitative paradigm was selected to explore the issues in a focus group comprising industry, legal expert and academic contributors.

A critique of the literature on relevant environmental law issues including contaminated land, waste management, water pollution, environmental impact assessment (EIA) issues and finally the political agenda is presented. Contaminated land, waste management, regulators and legislation were discussed in the focus group. The participants contributed their experiences and proposed several changes to environmental law. However, water pollution and EIAs were not considered by the contributors.

Developers face many environmental law challenges when endeavouring to progress housing on brownfield sites including contaminated land, funding, waste treatment permits, water pollution and EIAs. The benefits of the remediation of brownfield sites for housing seem to be a political priority, but reform of challenging environmental law issues less so. Understandably, the legal complexities of Brexit will take precedence.

The literature review identified the need to research the experience of brownfield environmental law challenges and recommended changes to environmental law from industry, legal experts and academia.

The purpose of this study is to solve five key brownfield valuation problems.

This aim is achieved by using doctoral research on integrating the scientific process into the appraisal process. The first objective is demonstrating why four of the problems require solutions prior to solving the first problem, a valuation procedure for formerly used sites. A second objective is to use empirical data from appraisals to reveal why existing methodology is not reliable – because it does not solve the four problems.

The resulting findings are that a developmental model that incorporates the Triad approach to quantifying environmental uncertainty, initially used in the USA, simulates a process used by buyers to establish the price paid for brownfields with contaminated land.

The practical implication that results from this research is that valuers need to emulate the buyer's process when valuing this property type. Prescriptive procedures for valuation requiring the use of scientific methods, as used in the Triad process, need to be set forth to quantify the atypical uncertainties in valuing this property type. The results of this research should be of significant interest to all stakeholders that are involved in brownfield redevelopment, so that they can insure that their needs will be met by improved feasibility analysis.

This research is unique in that it is the first empirical test of the reliability of the valuation of brownfields that need to undergo a time‐consuming and often expensive soil remediation process.

The increasing African population and economic growth leading to urbanisation continues to increase the need to redevelop brownfields as a strategy of encouraging sustainable development of cities, in particular in Ethiopia. However, the adoption of brownfield redevelopment in Ethiopia is at initial stage. Thus, the purpose of this paper is to highlight the framework based on grey-incidence decision-making approach to manage brownfields in African countries by taking Ethiopia as case example. The grey-incidence decision-making model integrates multiple factors such as economic, social, environmental, technical and associated risks and provides an effective decision-making and management tool for environmental practitioners and government agencies.

Questionnaires were used to collect data on terms and definitions of brownfield. The questions were prepared on the basis of currently used definitions developed by a number of developed countries. Moreover, this study utilises a grey-incidence decision-making approach to help in management and decision-making for the implementation of brownfield redevelopment projects (BRPs) in the remediated sites.

Standard definition of brownfield and essential guidelines for brownfield redevelopment is proposed for Ethiopian context. The research findings were tested and verified using literature data and survey from major stakeholders. In addition, the grey-incidence decision-making approach is applied for the evaluation of BRPs in the remediated sites. A framework is proposed to control future brownfields for African countries by taking Ethiopia as a case example.

This research stresses the significance of an urban structure to address sustainable development, and the need to consider redevelopment of brownfields and identify the potential for a specific government policy framework. This research provides the best opportunity for Ethiopia by devising an urban land policy and create a strategy to contribute social, economic, financial and environmental benefits. It also provides a foundation to solve environmental issues by involving all major stakeholders, including community citizens, environmentalists and government agencies, and it also serves as guidelines to transform brownfields into Greenfields; and finally, it contributes to achieve the 2030 UN global goals.

Agencies responsible for remediation and long-term stewardship of areas with chemical and radiological contamination are feeling the pressure to increase public participation in decision-making. Much of the literature outlining advice for how best to involve the public in collaborative decision-making implicitly assumes that there is one best design for such processes.

We report on an empirical investigation into what participants in a process to establish a standard for remediation of plutonium in soil around the Rocky Flats facility near Denver, Colorado think about the most appropriate way to conduct such a decision-making process with public participation. Tapping subjective beliefs and preferences with an approach called Q methodology, we collected in-depth qualitative and quantitative data from 12 experienced participants and agency staff. Analysis of these data revealed three distinct perspectives on what would be the ideal decision-making process for this context. Two of the perspectives emphasized the need to link remediation and stewardship planning, while the third was characterized by the view that these are distinct, sequential activities.

Planners should assume that there may be multiple ideas about what is the most appropriate public participation process for a given situation. Continuing disagreement about the need to link remediation and stewardship can be reflected in disputes about process design. Success should be viewed as a function not only of the design features used but also the extent to which the design matches the needs and preferences of the participants.

The purpose of this paper is to investigate how the remediation of contaminated land has been damaged, perhaps immeasurably, in a period of devastating and crushing austerity.

A legal doctrinal and regulatory analysis of the contaminated land regime under Part 2A of the Environmental Protection Act (EPA) 1990 was used to investigate the extent to which austerity changes have affected future contaminated land identification and remediation.

Austerity changes have impacted upon Part 2A of the EPA 1990, the planning system and development incentives. The recent changes are going to contribute to the problem of the under-resourcing of local authorities and are likely to reduce voluntary remediation by developers. As a result, future contaminated land clean-up is going to decrease.

Originality/value is assured because, as far as the author is aware, there is no other literature in this research area dealing specifically with the coalition’s adverse impact on Part 2A; this paper fills the knowledge gap that existed in the research field.

“Location” is undoubtedly one of the most important factors in deciding whether or not to undertake a property development; however, when considering the redevelopment of a “brownfield” site it may be only one of a number of issues which need to be considered as part of the decision‐making process. Issues such as the environmental and economic cost of reclaiming or remediating land will assume an importance which does not exist with greenfield sites. The potential for harm, both to human beings and to the wider environment, will have to be considered, especially if any contamination is to be left on the site. Many brownfield sites are small in size, requiring the assembly of a number of sites, in different ownerships, in order to have a viable development project and they may also be plagued with problems such as inadequate access and obsolete services. The availability of tax incentives, or indeed penalties, to encourage brownfield redevelopment, together the possibility of obtaining insurance cover, will need to be factored into a valuation or development appraisal. This paper considers the issues to be considered as part of the decision making process. Some issues relate specifically to the assessment of risk, such as the potential for harms to humans, buildings or the environment, but taken altogether they should form part of a risk assessment strategy to determine the viability of development projects and the value, positive or negative, of brownfield development land. The paper reports on a survey of surveyors, developers and other professionals undertaken in the second half of 1998. It concludes that, while property professionals do not undertake a formal “risk assessment” procedure, they do take account of environmental as well as financial issues when deciding whether or not to proceed with the redevelopment of brownfield land.
