Abstract

International comparisons of contractor performance can provide robust benchmarks for contractors in different countries and help to identify ways towards performance improvement. Based on a hypothetical construction project, overall contractor performance (OCP) in Japan, the UK and the USA is compared. Overall contractor performance is defined to embrace construction cost, construction time, construction quality and sustainable development, the philosophy being that the achievement of one aspect of performance should not be at the expense of another. Multiple regression analysis reveals that overall contractor performance is dependent on: their past performance on previous similar projects; their commitment towards lifetime employment; their perceived importance of time performance; their relationship with subcontractors; and the number of design variations during construction. To improve their overall performance, contractors are advised to focus on construction time, reduce delays, maintain a stable workforce and establish partnerships with their subcontractors. Clients should attempt to reduce design variations during construction.

Abstract

Purpose

In modern urban governance, rescue materials storage points (RMSP) are a vital role to be considered in responding to public emergencies and improving a city's emergency management. This study analyzes the siting of community-centered relief supply facilities.

Design/methodology/approach

Combining grey relational analysis, complex network and relative entropy, a new multi criteria method is proposed. It pays more attention to the needs of the community, taking into account the use of community hospitals, fire centers and neighborhood offices to establish small RMSP.

Findings

The research results firstly found suitable areas for RMSP site selection, including Hanyang, Qiaokou, Jiangan and Wuchang. The top 10 nodes in each region are found as the location of emergency facilities, and the network parameters are higher than ordinary nodes in traffic networks. The proposed method was applied in Wuhan, China and the method was verified by us-ing a complex network model combined with multi-criteria decision-making for emergency facility location.

Practical implications

This method solves the problem of how to choose the optimal solution and reduces the difficulty for decision makers. This method will help emergency managers to locate and plan RMSP more simply, especially in improving emergency siting modeling techniques and additionally in providing a reference for future research.

Originality/value

The method proposed in this study is beneficial to improve the decision-making ability of urban emergency departments. Using complex networks and comprehensive evaluation techniques, RMSP is incorporated into the urban community emergency network as a critical rescue force. More importantly, the findings highlight a new direction for further research on urban emergency facilities site selection based on a combination of sound theoretical basis as well as empirical evidence gained from real life case-based analysis.

Highlights:

  1. Material reserve points are incorporated into the emergency supply network to maintain the advantage of quantity.

  2. Build emergency site selection facilities centered on urban communities.

  3. Use a complex network model to select the location of emergency supplies storage sites.

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

This paper aims to clarify the resistance degree of group road logistics to flood disaster resilience. The paper measures the resilience of group road logistics by establishing network structure model. The purpose of this study is to improve the resilience of road log.

Design/methodology/approach

This paper adopts Delphi method to collect data, interviews mainly flood management experts and supply chain risk management experts, and then analyzes the data through the network structure model combined with interpretative structure model (ISM) and analytical network process (ANP).

Findings

The results show that flood frequency and drainage systems are the main factors affecting the resilience of road transport logistics in urban areas. These research results provide useful guidance for the effective planning and design of urban road construction and infrastructure.

Research limitations/implications

However, the main factors affecting the resilience of road transport logistics are likely to change with the development of factors such as climate, economy and environment. Therefore, in future work, the authors' research will focus on the further application of this evaluation method.

Practical implications

The results show that the impact of flooding on the four dimensions of road logistics resilience varies. This shows that in deciding what intervention measures are to be taken to improve the resilience of the road network to flooding, various measures need to be considered.

Social implications

This paper provides a more scientific analysis of the risk management ability of the road network in the face of floods. In addition, it also provides a useful reference for urban road planners.

Originality/value

This paper addresses a clear need to study how to build models to improve the resilience of road logistics in flood risk.

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

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

Adequate reliable property market data are critical to the production of professional and ethical valuations as well as better real estate transaction decision-making. However, the availability of reliable property market information represents a major barrier to improving valuation practices in Ghana and it is regarded as a key challenge. The purpose of this paper is to investigate the sources and reliability of property market information for valuation practice in Ghana. The aim is to provide input into initiatives to address the availability of reliable property market data challenges.

Design/methodology/approach

A mixed methods research approach is used. The study, thus, relies on a combination of a systematic identification and review of literature, a stakeholder workshop and a questionnaire survey of real estate valuers in Accra, Ghana’s capital city to obtain requisite data to address the aim.

Findings

The study identifies seven property market data sources used by valuers to obtain market data for valuation practice. These are: valuers own database; public institutions; professional colleagues; property owners; estate developers; estate agents; and the media. However, access to property market information for valuations is a challenge although valuers would like to use reliable market data for their valuations. This is due to incomplete and scattered nature of data often borne out of administrative lapses; non-disclosure of details of property transactions due to confidentiality arrangements and the quest to evade taxes; data integrity concerns; and lack of requisite training and experience especially for estate agents to collect and manage market data. Although professional colleagues is the most used market data source, valuers own databases, was regarded as the most reliable source compared to the media, which was considered as the least reliable source.

Research limitations/implications

Findings from the study imply a need for the development of a systematic approach to property market data collection and management. This will require practitioners to demonstrate care, consciousness and a set of data collection skills suggesting a need for valuers and estate agents to undergo regular relevant training to develop and enhance their knowledge, skills and capabilities. The establishment of a property market databank to help in the provision of reliable market data along with a suitable market data collection template to ensure effective and efficient data collection are considered essential steps.

Originality/value

The study makes a significant contribution to the extant knowledge by providing empirical evidence on the frequency of use and the reliability of the various sources of market data. It also provides useful insights for regulators such as the Ghana Institution of Surveyors (GhIS), the Royal Institution of Chartered Surveyors (RICS) and other stakeholders such as the Commonwealth Association of Surveying and Land Economy (CASLE) and the Government to improve the provision of reliable property market information towards developing valuation practice not only in Ghana, but across the Sub-Saharan Africa Region. Also, based on these findings, the study proposes a new property market data collection template and guidelines towards improving the collection of effective property market data. Upon refinement, these could aid valuation practitioners to collect reliable property market data to improve valuation practice.

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

Purpose

Improved management of commercial property at risk from flooding may result from well-targeted advice from built environment (BE) professionals, such as surveyors, valuers and project managers. However, research indicates that the role of these professionals in providing such advice is currently limited for a variety of reasons. This paper aims to investigate the (perceived and real) barriers and opportunities for providing such advice in a number of international locations. In particular, the research sought greater understanding of the link between regulation and guidance; perceived roles and capacity; and training and education needs.

Design/methodology/approach

To cover different international settings, an illustrative case study approach was adopted within the selected countries (Australia, UK, USA, China and Germany). This involved a qualitative approach using semi-structured interviews of BE professionals with experience of advising on commercial properties at risk of flooding. Due to the specific nature of these interviews, a purposive sampling approach was implemented, leading to a sample of 72 interviews across the five international locations.

Findings

Perceived barriers were linked to regulatory issues, a shortage of suitably experienced professionals, a lack of formal guidance and insurance requirements. BE professionals defined their roles differently in each case study in relation to these factors and stressed the need for closer collaboration among the various disciplines and indeed the other key stakeholders (i.e. insurers, loss adjusters and contractors). A shortage of knowledgeable experts caused by a lack of formal training, and education was a common challenge highlighted in all locations.

Originality/value

The research is unique in providing an international perspective on issues affecting BE professionals in providing robust and impartial advice on commercial property at risk of flooding. While acknowledging the existence of local flood conditions, regulatory frameworks and insurance regimes, the results indicate some recurring themes, indicating a lack of general flood risk education and training across all five case study countries. Learning across case studies coupled with appropriate policy development could contribute toward improved skills development and more consistent integration of BE professionals within future flood risk management practice, policy and strategy.

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.
