Abstract

Purpose

The purpose of this paper is to identify challenges faced in resource management in the UK construction industry and to propose some solutions to these problems.

Design/methodology/approach

Based on a qualitative research methodology, 14 experts from the UK construction industry were chosen to be participants in the study. The participants were equally divided into two focus groups to discuss resource management using five projects as case studies. Thematic analysis of the discussion reveals seven key factors that affect resource management.

Findings

The results show that most of the problems identified are due to poor data management processes and the practice of having data in silos. Overcoming this challenge requires the adoption of big data approaches for resource management to allow the integration of large and different forms of data.

Originality/value

This study seeks to bring to the fore challenges faced in resource management by the UK construction industry and to outline some solutions to address them.

Abstract

Purpose

In a circular economy, the goal is to keep materials values in the economy for as long as possible. For the construction industry to support the goal of the circular economy, there is the need for materials reuse. However, there is little or no information about the amount and quality of reusable materials obtainable when buildings are deconstructed. The purpose of this paper, therefore, is to develop a reusability analytics tool for assessing end-of-life status of building materials.

Design/methodology/approach

A review of the extant literature was carried out to identify the best approach to modelling end-of-life reusability assessment tool. The reliability analysis principle and materials properties were used to develop the predictive mathematical model for assessing building materials performance. The model was tested using the case study of a building design and materials take-off quantities as specified in the bill of quantity of the building design.

Findings

The results of analytics show that the quality of the building materials varies with the building component. For example, from the case study, at the 80th year of the building, the qualities of the obtainable concrete from the building are 0.9865, 0.9835, 0.9728 and 0.9799, respectively, from the foundation, first floor, frame and stair components of the building.

Originality/value

As a contribution to the concept of circular economy in the built environment, the tool provides a foundation for estimating the quality of obtainable building materials at the end-of-life based on the life expectancy of the building materials.

Abstract

Purpose

Earlier studies on risk evaluation in private finance initiative and public private partnerships (PFI/PPP) projects have focussed more on quantitative approaches despite increasing call for contextual understanding of the bankability of risks. The purpose of this paper is to explore the perspectives of UK PFI financiers’ regarding the bankability of four critical risks (construction and completion risk, operations, supply and offtake risk) in PPP projects.

Design/methodology/approach

Multiple case study strategy was adopted to investigate the phenomenon within real-life context of PFI/PPP projects in UK. Using purposive sampling approach, the study examined school and road PFI/PPP projects through interviews, documentations and focus group discussions.

Findings

Results from the study unravelled 36 suitable bankability criteria and some mitigation strategies for evaluating the four critical risks in PFI/PPP during due diligence appraisal. Further evidences from the study also show that, financiers’ bankability criteria, when paired along with corresponding risks and mitigation strategies within with a single framework, provides a quick and effective view of bankability of risks in PFI/PPP funding application.

Research limitations/implications

In order to ensure generalisability of findings, only projects with similar nature were selected from just two sectors of the UK economy (road and education sectors). The context of the study is also based on UK’s PFI/PPP and Construction Industry, as such, other geographical regions in Europe and beyond have not been contextualised in this study. Due to the significance of finance in PFI/PPP contracts, only the perspective of project financiers have been explored in this study.

Practical implications

This study provides a less complicated but useful understanding of how risks in PFI/PPP projects may be packaged in a bankable manner to secure the confidence of project financiers. By presenting a qualitative framework, the study addresses concerns of over quantification of risk analysis in PFI/PPP appraisals and provides a relatable approach useful for non-finance oriented PPP practitioners.

Social implications

This study addresses the social concerns of too much complexity and ambiguity in PFI/PPP structuring especially regarding factors that could make a project acceptable to lenders.

Originality/value

The study proposes a “Bankability and Risk Qualitative Framework”, which presents bankability information on critical risks in clear manner and represents critical parameters for winning financiers’ funding approvals for PFI/PPP projects.

Abstract

Purpose

The purpose of this paper is to highlight the use of the big data technologies for health and safety risks analytics in the power infrastructure domain with large data sets of health and safety risks, which are usually sparse and noisy.

Design/methodology/approach

The study focuses on using the big data frameworks for designing a robust architecture for handling and analysing (exploratory and predictive analytics) accidents in power infrastructure. The designed architecture is based on a well coherent health risk analytics lifecycle. A prototype of the architecture interfaced various technology artefacts was implemented in the Java language to predict the likelihoods of health hazards occurrence. A preliminary evaluation of the proposed architecture was carried out with a subset of an objective data, obtained from a leading UK power infrastructure company offering a broad range of power infrastructure services.

Findings

The proposed architecture was able to identify relevant variables and improve preliminary prediction accuracies and explanatory capacities. It has also enabled conclusions to be drawn regarding the causes of health risks. The results represent a significant improvement in terms of managing information on construction accidents, particularly in power infrastructure domain.

Originality/value

This study carries out a comprehensive literature review to advance the health and safety risk management in construction. It also highlights the inability of the conventional technologies in handling unstructured and incomplete data set for real-time analytics processing. The study proposes a technique in big data technology for finding complex patterns and establishing the statistical cohesion of hidden patterns for optimal future decision making.

Abstract

Purpose

Against the backdrop of the contribution of design to the occurrence of occupational injuries and illnesses in construction, design for occupational safety and health (DfOSH) is increasingly becoming prominent in the construction sector. To ensure that design interventions are safe for construction workers to build and maintain, design firms need to have the appropriate organisational capability in respect of DfOSH. However, empirical insight regarding the attributes that constitute DfOSH organisational capability is lacking. The purpose of this paper, which trailblases the subject of DfOSH organisational capability in construction, is to address two key questions: what organisational attributes determine DfOSH capability? What is the relative priority of the capability attributes?

Design/methodology/approach

The study employed three iterations of expert focus group discussion and a subsequent three-round Delphi technique accompanied by the application of voting analytic hierarchy process.

Findings

The study revealed 18 capability attributes nested within six categories, namely: competence (the competence of organisation’s design staff); strategy (the consideration of DfOSH in organisation’s vision as well as the top management commitment); corporate experience (organisation’s experience in implementing DfOSH on projects); systems (systems, processes and procedures required for implementing DfOSH); infrastructure (physical, and information and communication technology resources); and collaboration (inter- and intra-organisational collaboration to implement DfOSH on projects). Whilst these categories and their nested attributes carry varying weights of importance, collectively, the competence-related attributes are the most important, followed by strategy.

Originality/value

The findings should enable design firms and other key industry stakeholders (such as the clients who appoint them) to understand designers’ DfOSH capability better. Additionally, design firms should be able to prioritise efforts/investment to enhance their DfOSH capability.

Abstract

Purpose

A major challenge for foreign lenders in financing public private partnerships (PPP) infrastructure projects in an emerging market (EM) is the bankability of country-related risks. Despite existing studies on country risks in international project financing, perspectives of foreign lenders on bankability of country-specific risks in an EM is yet to be explored. Hence, using a mixed methodology approach, three private finance initiatives/PPP projects in Sub Saharan Africa (Nigeria) were used to investigate political risk, sponsor, concession and legal risks in PPP loan applications. The paper aims to discuss these issues.

Design/methodology/approach

The study adopted mixed methodological approach comprising focus group discussions and analysis of loan documents obtained from foreign project lenders, in addition to the questionnaire survey distributed to local and international project financiers with experiences in PPPs within Nigeria.

Findings

Results identified seven topmost bankability criteria for evaluating country-related risks (political risk, sponsor, concession and legal risks) in EM PPPs. In addition, a “Risk and Bankability Framework Model” was developed from the study presenting critical parameters for gaining foreign funding approval for EM’s PPP loan applications.

Research limitations/implications

Since the study only explored bankability of PPPs in Sub Saharan Africa with the exclusion of other geographical regions, the proposed framework model should be taken in context of EMs as a mind-map for foreign lenders and local private investors seeking to finance PPPs in an EM.

Practical implications

Results from the study represent critical parameters for winning foreign loan approval for PPP infrastructure projects within an EM context.

Originality/value

Study proposed “Risk and Bankability Framework Model” relevant for evaluating PPP loan applications at the pre-approval stage for EM PPPs.

Abstract

Purpose

Although the UK Guarantee Scheme for Infrastructures (UKGSI) was introduced in 2012 to address the huge financing gap for critical infrastructures, PFI sponsors have so far guaranteed only few projects. Many stakeholders in the project finance industry have blamed this situation on lack of general understanding of strategies for harnessing the benefits of the government guarantee scheme. The purpose of this paper is to investigate the perspectives of UK’s PFI/PPP stakeholders on critical factors influencing approval for government guarantees using the UKGSI as a focal point.

Design/methodology/approach

Using a mixed methodology approach, this study identified 26 important criteria used in evaluating government guarantee applications through focus group discussions with PFI stakeholders. The identified criteria were then put in questionnaire survey to 195 respondents within the UK PFI/PPP industry.

Findings

Through factor analysis, five critical factors determining successful government guarantee application were unravelled. These include: compliance with UK National Infrastructure Plan; demonstration of project bankability and risk management; value for money; proof of projects’ dependence on government guarantee; and certainty of planning commission’s approval.

Originality/value

Results of this study will facilitate an in-depth understanding of critical factors necessary for accessing government guarantee scheme for PFI/PPPs, while also improving the bankability of potential PFI projects.

Abstract

This study explored use of big data analytics (BDA) to analyse data of a large number of construction firms to develop a construction business failure prediction model (CB-FPM). Careful analysis of literature revealed financial ratios as the best form of variable for this problem. Because of MapReduce’s unsuitability for iteration problems involved in developing CB-FPMs, various BDA initiatives for iteration problems were identified. A BDA framework for developing CB-FPM was proposed. It was validated by using 150,000 datacells of 30,000 construction firms, artificial neural network, Amazon Elastic Compute Cloud, Apache Spark and the R software. The BDA CB-FPM was developed in eight seconds while the same process without BDA was aborted after nine hours without success. This shows the issue of not wanting to use large dataset to develop CB-FPM due to tedious duration is resolvable by applying BDA technique. The BDA CB-FPM largely outperformed an ordinary CB-FPM developed with a dataset of 200 construction firms, proving that use of larger sample size with the aid of BDA, leads to better performing CB-FPMs. The high financial and social cost associated with misclassifications (i.e. model error) thus makes adoption of BDA CB-FPMs very important for, among others, financiers, clients and policy makers.

Abstract

Purpose

Competency-based measure is increasingly evident as an effective approach to tailoring training and development for organisational change and development. With design stage widely reckoned as being decisive for construction waste minimisation, the purpose of this paper is to identify designers’ competencies for designing out waste.

Design/methodology/approach

Due to paucity of research into competency for construction waste mitigation, this study corroborates verbal protocol analyses (VPA) with phenomenological research.

Findings

Combining findings from the two methodological approaches, competencies for designing out waste are grouped into five categories, three of which are largely task related and two being contextual competencies. The study suggests that design task proficiency, low waste design skills and construction-related knowledge are indispensable task competencies, while behavioural competence and inter-professional collaborative abilities are requisite contextual competencies for designing out waste. In concurrence with task-contextual theory of job performance, personality variables and cognitive abilities are found to influence one another. This suggests that both task and contextual competencies are not only important, they are less mutually exclusive with respect to designing out waste.

Practical implications

This study implies that apart from commitment and dedication of designers to waste minimisation, design and firm practices are expected to be adapted to the industry’s standard.

Originality/value

Basis for training needs of design professionals as well as redeployment criterion are further elaborated in the paper. By enhancing competencies identified in this study, construction waste would not only be significantly designed out, adequate cost saving could be made as a result of waste reduction.

Abstract

Purpose

This study explores the challenges of access to finance from local financial institutions (LFIs), i.e. local banks, for public–private partnership (PPP) infrastructure project delivery in Nigeria. The aim is to provide useful insights that could inform policy solutions to ease the local funding of PPP infrastructure projects in Nigeria and, by extension, other developing economies.

Design/methodology/approach

Adopting a qualitative research methodology, the study engaged PPP stakeholders involved in securing funds for PPP infrastructure projects in Nigeria. A total of 15 PPP stakeholders, drawn from the public and private sectors, were purposively selected and their views on the research problem obtained through recorded telephone interviews. The opinions of the research participants were subsequently analyzed and the results discussed with the outcome of the examination of relevant literature.

Findings

The study found that the significant factors affecting access to local finance for PPP infrastructure projects in Nigeria include low capital base by LFIs, weak project viability, lack of capacity to manage PPP-related activities, inconsistent government policy, poor legal framework and public perception of PPP.

Research limitations/implications

Insights from this study are useful for PPP stakeholders in mitigating the barriers that influence access to local finance for PPP infrastructure projects in Nigeria and other developing economies. This study is also useful in enhancing the current policy structure in developing countries as a way of revamping the existing infrastructure framework through LFIs.

Originality/value

This study provides clarity on the peculiar challenges impeding access to finance from LFIs for PPP infrastructure projects in Nigeria and will be useful for debt providers and policymakers in evaluating the bankability of PPP infrastructure projects in Nigeria and other developing countries.
