Abstract

Purpose

Flood resilience is emerging as a major component of an integrated strategic approach to flood risk management. This approach recognizes that some flooding is inevitable and aligns with the concept of “living with water.” Resilience measurement is a key in making business case for investments in resilient retrofits/adaptations, and could potentially be used to inform the design of new developments in flood prone areas. The literature is, however, sparse on frameworks for measuring flood resilience. The purpose of this paper is to describe the development of a fuzzy logic (FL)-based resilience measuring model, drawing on a synthesis of extant flood resilience and FL literature.

Design/methodology/approach

An abstraction of the flood resilience system followed by identification and characterization of systems’ variables and parameters were carried out. The resulting model was transformed into a fuzzy inference system (FIS) using three input factors: inherent resilience, supportive facilities (SF) and resident capacity.

Findings

The resulting FIS generates resilience index for households with a wide range of techno-economic and socio-environmental features.

Originality/value

It is concluded that the FL-based model provides a veritable tool for the measurement of flood resilience at the level of the individual property, and with the potential to be further developed for larger scale applications, i.e. at the community or regional levels.

Abstract

The results of a model based survey of contractors' planning engineers in France and the UK suggest that planned completion times for constructing an identical high‐rise in situ concrete framed structure are significantly and dramatically lower in France than in the UK. Average planned construction periods in France were 13 weeks, some 9 weeks faster than the UK average of 22 weeks. Since planned construction periods reflect past experience, French contractors apparently achieve superior levels of production performance whilst at the same time working fewer hours per week, utilizing directly employed workers and employing fewer supervisors. If such planned completion times are truly representative, the findings indicate comparatively poor UK contractor performance, and signify future problems for the British builder in the emerging European marketplace. The causes of such poor performance are complicated, but based on indicative French best practices: production is enhanced when scheduled overtime is avoided, a directly employed and mainly skilled workforce is engaged, and a maximum working time of 40 hours per week is the norm rather than the exception.

Abstract

Purpose

Providing accessible and inclusive environments fulfils legislative obligations and creates financial benefits. Historic-listed buildings rely on heritage tourism for continued financial support. The purpose of this paper is to investigate how historic-listed buildings adapt to afford access to people with disabilities (PwD), through physical and non-physical interventions.

Design/methodology/approach

Using a case study approach of an historic property, research comprises of: an observational visitor survey, determining visitor demographic regarding visible disabilities; an access audit, determining current accessibility; interviews with the property’s Access Team; and desktop-based research.

Findings

The results depict the complexity, challenges and barriers in making historic buildings accessible for PwD. Through alternative training and inclusive initiatives, the findings reveal how historic buildings may support the multiplicity of individuals’ access requirements.

Research limitations/implications

Further research incorporating longer surveying periods, wider demographic of interviewees and multiple case study analysis would provide richer, comparable data in understanding the intrinsic complexities involved in creating accessibility within historic buildings. The implications of this research could transcend management, conservation and adaptation of listed buildings in identifying the defined barriers and solutions to overcome them.

Originality/value

The originality of this paper relates to the use of alternative services creating access when physical changes are deemed “unreasonable”. A conceptual framework is developed depicting the complexity, challenges and barriers in making historic buildings accessible for PwD.

Abstract

Purpose

Health and safety in small construction firms is often neglected by owners leading to poor health and safety performance and unacceptably high fatality and injury rates. A body of knowledge has established significant links between the motivational behaviours of operatives towards health and safety. Motivation is also considered as a key tool for improving operative productivity as when operatives experience safe worksites, they can carry out their work in a more productive manner. The purpose of this research is to develop a framework to examine the motivational factors that affect operative health and safety in small construction firms.

Design/methodology/approach

A critical review and synthesis of the body of knowledge incorporating motivational theory, health and safety literature and the factors which characterise small firms, is used to develop the framework.

Findings

Key components of the framework include the presence of intrinsic and extrinsic components, appropriate health and safety policies and procedures, the type of work environment, the operatives (i.e. attitude, experience and training) as well as the presence of appropriate management and supervision. The study revealed that operatives in small firms are less likely to be extrinsically motivated due to the absence of training, management commitment, policies and the wider working environment

Research limitations/implications

Failure of motivational support can result in increased danger and risk in exposing operatives to injury in the small firm environment. In this context, the damage caused to operative's health and safety in small construction firms is dependent mainly on the extrinsic factors.

Practical implications

The framework provides a basis for improving our understanding of how to motivate operatives to act safely and will help to improve the health and safety performance of small firms. It is therefore vital to emphasise enhancement efforts on these extrinsic strategies in the small firms' environment especially in the initial stages of the project (or activity), so that the health and safety of operatives in small firms can be improved.

Originality/value

This study proposes a contribution in developing an understanding of the motivational factors and their influence on the health and safety of operatives in small construction firms. The study revealed that operatives in small firms are less likely to be extrinsically motivated and have only intrinsically motivated elements in their workplace. The study proposes an indirect link between the extrinsic and intrinsic factors that affect motivation.

Abstract

Purpose

There is a significant dearth of theoretical and practical knowledge with respect to the design and planning stages of post-conflict housing reconstruction projects. This research presents the development of a conceptual framework towards improving the design and planning processes of post-conflict housing reconstruction projects.

Design/methodology/approach

A systematic review of the literature on post-conflict housing reconstruction in developing countries, incorporating the themes of collaboration and stakeholder engagement, is presented. A synthesis of this literature is used to inform the development of a conceptual framework that seeks to address the limitations of current housing reconstruction models in post-conflict environments by establishing collaborative approaches at the initial stages of design, as well as the tasks required to achieve efficient results through the aid of relief organisations (NGOs).

Findings

While the review essentially identifies the fundamental issues and inadequacies of the current housing reconstruction models, the proposed framework aims to enable the implementation of better and efficient collaborative design and planning strategies and practices in post-conflict housing reconstruction.

Originality/value

The conceptual framework aims to promote more effective collaboration through the design of post-conflict housing reconstruction projects by strengthening communication and coordination between the key stakeholders. Furthermore, the research highlights several gaps in the extant literature, signposting new directions for future research in the area of stakeholder engagement during the design and planning post-conflict housing.

Abstract

Purpose

The purpose of this paper is to understand how built environment professionals approach the valuation of flood risk in commercial property markets and whether insurance promotes mitigation in different insurance and risk management regimes, draw common conclusions and highlight opportunities to transfer learning.

Design/methodology/approach

An illustrative case study approach involving literature search and 72 interviews with built environment professionals, across five countries in four continents.

Findings

Common difficulties arise in availability, reliability and interpretation of risk information, and in evaluating the impact of mitigation. These factors, coupled with the heterogeneous nature of commercial property, lack of transactional data and remote investors, make valuation of risk particularly challenging in the sector. Insurance incentives for risk mitigation are somewhat effective where employed and could be further developed, however, the influence of insurance is hampered by lack of insurance penetration and underinsurance.

Research limitations/implications

Further investigation of the means to improve uptake of insurance and to develop insurance incentives for mitigation is recommended.

Practical implications

Flood risk is inconsistently reflected in commercial property values leading to lack of mitigation and vulnerability of investments to future flooding. Improvements are needed in: access to adequate risk information; professional skills in valuing risk; guidance on valuation of flood risk; and regulation to ensure adequate consideration of risk and mitigation options.

Originality/value

The research addresses a global issue that threatens local, and regional economies through loss of utility, business profitability and commercial property value. It is unique in consulting professionals across international markets.

Abstract

Purpose

Recent changes in climate, rainfall patterns, snow melt and rising sea levels coupled with an increase in urban development have increased the threat of flooding. To curb these threats and mitigate these damages, property-level approaches to improving resilience are now being encouraged as part of an integrated approach to flood risk management. This raises questions such as, what are the flood resilient attributes within individual properties, what is their importance and how can these be quantified. This research sought to develop a quantitative approach for the measurement of property-level flood resilience.

Design/methodology/approach

A synthesis of literature was undertaken to establish the main resilient attributes and their relevant sub-attributes. This process led to the development of a new method, named the Composite Flood Resilient Index (CFRI) to weight the attributes and sub-attributes of flood resilience based on their importance. The approach adopts the use of the fuzzy-analytic hierarchy process (F-AHP) approach to quantify flood resilience.

Findings

The implications of the proposed methodology in determining the flood resilience of individual property, including the potential use in retrofitting activities, and the benefits to a range of stakeholders are considered.

Social implications

The methodology offers the potential to support the measurement of flood resilience of individual properties, allowing the identification and prioritisation of specific interventions to improve the resilience of a property.

Originality/value

Whereas previous attempts to quantify flood resilience have adopted qualitative approaches with some level of subjectivity, this proposed methodology represents an important advancement in developing a scientific and quantitative approach.

Abstract

Purpose

Client satisfaction is one of the major determinants of project success and therefore is a fundamental issue for construction participants who must constantly seek to improve their performance if they are to survive in the marketplace. However, client satisfaction has remained an elusive issue for a majority of construction professionals. This research aims to investigate the performance of construction consultants to determine those key performance attributes which have a crucial impact on client satisfaction, and from that to identify ways of improving the services provided by such consultants.

Design/methodology/approach

This research presents the results of a UK‐wide client satisfaction survey based on the performance of a large engineering and management consultancy organisation whom they employed.

Findings

Results indicate that key performance attributes for consultants including technical accuracy; overall quality of services and people, have been identified as the main client satisfaction criteria. Clients consider effective communications and their service providers as being most important in determining their satisfaction levels. Furthermore, it is revealed that clients' strategic decisions and the overall performance of consultants in those key areas make a significant contribution towards client satisfaction.

Originality/value

The outcome of this research will improve the understanding of the client satisfaction phenomenon and benefit clients and construction consultants.

Abstract

Purpose

The Environment Agency estimates that one in six homes in England (approximately 5.2m properties) are at risk from flooding and 185,000 commercial properties are located in flood-prone areas. Further, an estimate of 10,000 new homes are built on flood plains yearly. The UK has witnessed a significant increase in flood events over the past 10 years. During this period, there has been growing research attention into measures to mitigate the effects of flooding, including the benefits of deploying sustainable urban drainage systems (SuDs) in new developments or as a retrofit. The purpose of this paper is to present the development of a cost-benefit analysis model for the retrofit of SuDs focusing on the potential for improved flood risk mitigation in the context of commercial properties.

Design/methodology/approach

A synthesis of flood risk management and SuDs literature is used to inform the development of a conceptual cost-benefit analysis model for the retrofit of SuDs and focusing on the potential for improved flood risk mitigation in the context of commercial properties.

Findings

SuDs have been applied successfully in different parts of the world; however, the uptake of SuDs, in particular, the retrofit of SuDs, has been restricted by a number of issues including a lack of experience and trust in their performance and a lack of understanding in their true benefits. In particular, there is the limited experience of retrofitting SuDs and there are no well-established procedures for evaluating the feasibility, value or cost effectiveness of doing this.

Social implications

This offers the potential to support the UK government’s flood risk management policy by helping to increase the resilience of properties, whilst offering other benefits to communities such as improvements in air quality and biodiversity and also presenting a clearer understanding of the monetary and non-monetary implication to owners of commercial properties for a more informed and acceptable uptake of SuDs retrofit.

Originality/value

The proposed model will allow a more comprehensive understanding of the costs and associated benefits associated with SuDs retrofit, highlighting the flood risk mitigation benefits that might accrue over a period of time for commercial property.

Abstract

An assessment of the performance of UK clients on 55 ‘case projects’ as considered by contractors is presented and used to develop models of contractors' satisfaction. Principal component analysis (PCA) reveals five dimensions to contractor satisfaction, classified in this research as (i) support provided to contractors, (ii) clients' attitude, (iii) clients' understanding of their own needs, (iv) quality of clients' brief, and (v) financial aspects of performance. Knowledge of these models should enable clients to perform better, which is conducive towards satisfactory participant performance and overall project performance. The models identify three key aspects of client performance that are found to significantly influence contractors' satisfaction levels, namely, (i) the capability of the client's representative, (ii) the client's past performance and project management experience and (iii) the financial soundness and reputation of the client. Additionally, the nature of the project and certain characteristics of contractors also influence satisfaction levels. The models demonstrated accurate predictive power and were found to be valid and robust. Clients could use the models to help improve their performance, leading to more successful project implementation. This will also promote the development of harmonious working relationships within the construction project coalition (PC).
