Abstract

Purpose

Environmental risks (ERs) are critical to any highway construction project (HCP). One of the main contracting parties responsible for ERs is the contractor. Hence, it has been crucial to look into ways to control ERs in HCPs from the contractor’s perspective. This study aims to investigate how ERs can be managed in HCP in Sri Lanka.

Design/methodology/approach

A quantitative research approach with three rounds of Delphi was used. Statistical techniques were used to analyse and validate the ERs, the parties to whom the risks were to be allocated, and risk management measures identified from the empirical data collection.

Findings

The study reveals the 11 most significant ERs for HCP. Further, the most significant ERs in HCP were mainly found to be the responsibility of contractors in Sri Lanka. Twenty-four most appropriate risk response measures were determined; 13 were found to be common measures that could be used to manage two or more risks, while the remaining 11 were unique to specific risks.

Originality/value

Overall, this research determines the most significant ERs in HCP, the best risk allocation among the parties and appropriate risk-handling strategies and measures for each significant ERs. Additionally, the study addresses the demand for ERs management in HCP.

Abstract

Purpose

Cost overrun is a significant issue in construction, an undesirable feature the industry has long been associated with. Poor procurement practices are often blamed for subsequent cost overruns in construction, especially with conventional procurement methods leading to outrageous cost overruns. The purpose of this study is to review the features of the new models of construction procurement (NMCP) and assess their potential to reduce cost overruns in construction projects.

Design/methodology/approach

A literature review was conducted to identify the issues of procurement leading to cost escalations. Primary data were obtained through exploratory, semi-structured interviews using a case study approach.

Findings

Clients’ lack of knowledge was highlighted as a key issue in procurement that interlinks with many factors causing cost escalation. The findings suggest that the features contained within the NMCP, such as early contractor involvement and collaboration throughout the project team, have the potential to make a positive contribution to addressing cost escalation in construction.

Research limitations/implications

The primary research was undertaken as an exploratory study and presents the contractor's perspective. Further research is therefore suggested, with multiple organisations representing all key stakeholders in a construction project, including clients, consultants, sub-contractors and suppliers.

Practical implications

The study recommends awareness of the NMCP be raised throughout the industry, and simplified information must be made available to help widen uptake of these contemporary procurement methods.

Originality/value

Addressing the dearth of research concerning the use of NMCP within the industry, this study makes a niche contribution to the body of knowledge on construction cost management by illustrating the potential offered by these new procurement methods for addressing cost escalation. For an industry where collaboration is accepted with reservations, this case study demonstrates how novel collaborative strategies such as open book costing, project bank accounts and shared pain and gain mechanisms can be implemented as part of the procurement strategy and how such strategies can contribute towards minimising the cost escalation inherent in construction projects.

Abstract

Purpose

The recent surge in light emitting diode (LED) lighting retrofitted into schools in the UK is as a result of the UK Government’s 2050 zero carbon pledge. However, the benefits and consequences of LED retrofit projects for staff and enablers and stakeholder knowledge gaps about LED lighting retrofitting have not been fully explored. The aim of this research is to determine the amount of savings in cost, carbon reduction and kilowatt usage and to confirm if repayment from energy and cost savings derived from LED retrofit school projects funded through the SALIX funding option in the UK would be enough to service the loan. Thus, it examines monetary and non-monetary benefits, internal project stakeholder knowledge gaps and the consequences of LED retrofit for the staff and enablers of a large community college in the UK which is funded through the SALIX funding option.

Design/methodology/approach

The methodology relied on a hybrid research approach of a case secondary school through the review of literature, analysis of secondary data, focus group and questionnaire survey. The focus group consists of six key project stakeholders. The secondary data was sourced from the Project IGP [Individual Grade Proposal] and the Positive Energy Report from Zenergi, and the closed online questionnaire survey was used to sample 150 teaching staff and school enablers.

Findings

The findings show that stakeholders lack project knowledge, trust and expertise/project comprehension. This is in terms of baseline information, LED technology/management, payback modalities, management of risks and ethical issues around environmental impact. The forecasted SALIX savings were not achieved in real-time, partly because it does not take into consideration the increase in energy costs over the payback period. However, the LED retrofit creates efficiencies; drives down energy costs and energy usage; and drives carbon reduction, helping pupils’ learning, improving productivity and performance, and finally leading to a better lighting environment for the school community.

Originality/value

The study will help schools in the UK that intend to access SALIX finance for LED retrofits to understand the challenges and mitigate the risks. It will also help the government to understand the importance of adjusting the payback modalities to the base price when the retrofit was carried out for real-time savings to be made. The research would be useful in ensuring the proactive involvement of all the identified stakeholders in understanding the challenges and what the function entails.

Abstract

Purpose

Reality suggests that the whole world is currently facing an unprecedented scale of natural disasters. Sri Lanka fell into this category after being one of the hardest hit countries of tsunami 2004. Irrespective of the major losses that tsunami 2004 resulted in, Sri Lanka is prone to certain natural disasters such as floods, landslides, etc., which frequently bring in severe damage throughout the country. Within the context of continuous occurrence of hazards and growing vulnerability, risk reduction has become one of the important solutions to mitigate disasters and for speedy recovery after a disaster. Disaster risk reduction entails measures to curb disaster losses by addressing hazards and the vulnerability of people, to them. Disaster risk reduction measures can be categorised in various ways. From another perspective, achieving best quality through reconstruction has shown poor results. However, there is a clear two‐way relationship between the concept of disaster risk reduction and quality of infrastructure, but it is not well explored. This paper aims to explore this issue.

Design/methodology/approach

Research on which this paper is based focuses on the need for investigating and exploring the relationship between disaster risk reduction and quality of infrastructure. Accordingly, this paper presents the background of the study based on a critical literature review, mainly the rationale behind selection of this particular research and the expected research approach to be adopted.

Findings

The findings suggest the notion that disaster risk reduction has an ability to influence the ultimate quality of a construction project, ultimately the success of the project.

Originality/value

There is a clear two‐way relationship between the concept of disaster risk reduction and quality of infrastructure, which is not yet well explored. This research will be further extended towards investigating this two‐way relationship.

Abstract

Purpose

The literature emphasises that integration of disaster risk reduction (DRR) into planning processes is a key to reduce natural disaster losses, boost socio‐economic development needs and ensure sustainability in development gains. But linking DRR to the infrastructure reconstruction sector has become a challenge in developing country settings. Therefore, the purpose of the main research, of which this paper is based on, is to explore how integration of DRR into infrastructure reconstruction should be done in such a way to contribute to socio‐economic development process. As a part of this main aim, this paper focuses on exploring the existing gap in the concept of DRR at the policy‐making level and the infrastructure reconstruction project level. Thus, the paper seeks to review the current policies on post‐disaster reconstruction and DRR at the national and intermediate‐organisational level in Sri Lanka and integration of DRR concept within these policies. Not limiting to the policies, DRR processes were assessed on their success through the level of implementation of DRR strategies at the post‐disaster infrastructure reconstruction projects.

Design/methodology/approach

The paper is based on the data collated from a case study conducted in a water supply and sanitation reconstruction project in Sri Lanka supported by expert interviews among national and intermediate‐organisational level policy makers those who are involved in the development of policies related to disaster management and construction activities.

Findings

The results highlight the lack of individual policies on reconstruction and DRR of reconstruction at the national and intermediate‐organisational level except certain sections within certain policies. It was found that integration of DRR within these policies is lower than the level of importance of such integration. Further, the level of implementation of these policies in practise is average as it is averted by required speed and quality of reconstruction, availability of finances for reconstruction, the scale of reconstruction projects, reliability and practicability of policies, legitimacy of policies and adequacy of authority delegated to the relevant bodies, the consistency of various policies, detail explanations on relationships with other policies, the level of awareness about policies by the relevant bodies, attitude of construction professionals and experience of reconstruction bodies in the field of disaster reconstruction.

Research limitations/implications

The findings of this paper is not limited to one specific policy related to disaster management or construction in Sri Lanka. It represents an overall view of most of the existing policies in the field. Furthermore, the data collection was limited to the Sri Lanka context.

Practical implications

The findings of this paper will be useful to relevant policy makers to understand the areas needed further attention within the policies in terms of integration of DRR concept within them.

Originality/value

The paper is unique in its findings as it discovers overall gaps in the concept of DRR within the policies and actual infrastructure reconstruction project practises.

Abstract

Purpose

Disasters provide physical, social, economic, political and environmental development windows of opportunity particularly through housing and infrastructure reconstruction. The reconstruction process should not be neglected due to the opportunistic nature of facilitating innovation in development. In this respect, post‐disaster “infrastructure” reconstruction plays a critical role in development discourse and is often essential to sustain recovery after major disasters. However, reconstruction following a natural disaster is a complicated problem involving social, economic, cultural, environmental, psychological, and technological aspects. There are significant development benefits of well‐developed “Disaster Risk Reduction (DRR) Strategies” and, for many reasons, the concept of DRR can be more easily promoted following a disaster. In this respect, a research study was conducted to investigate the effects of integrating DRR strategies into infrastructure reconstruction on enhancing the socio‐economic development process from a qualitative stance. The purpose of this paper is to document part of this research study; it proposes an approach that can be used to assess the influence of the application of the DRR concept into infrastructure reconstruction on socio‐economic development.

Design/methodology/approach

The research methodology included a critical literature review.

Findings

This paper suggests that the best way to assess the influence of integrating DRR strategies practices into infrastructure reconstruction on socio‐economic development is to assess the level of impact that DRR strategies has on overcoming various factors that form vulnerabilities. Having assessed this, the next step is to assess the influence of overcoming the factors that form vulnerabilities on achieving performance targets of socio‐economic development.

Originality/value

This paper primarily presents a framework for the concept of socio‐economic development and a modelled classification of DRR practices.
