Abstract

Purpose

The purpose of this paper is to select a suitable procurement method for steel building construction in Sri Lanka following a systematic method which weigh, both procurement selection factors and existing procurement systems.

Design/methodology/approach

An abductive research stance is followed in this empirical study. Procurement selection factors were selected through a critical literature review which was followed by a quantitative questionnaire survey. The collected data were analysed using descriptive statistical analysis and relative important index.

Findings

The critical literature review outlined 46 procurement selection factors, out of which 26 factors were very important in steel building procurement selection. Short construction period and higher constructability of design are ranked at the top with the highest priority rating factors. Management-oriented procurement system was selected as the most appropriate procurement system for steel building constructions within the Sri Lankan context.

Research limitations/implications

The study is limited to widely use three procurement systems in Sri Lankan construction industry. Yet, the process followed in selecting the most appropriate procurement system could be applied for other contexts. The implications of the study are mainly identifying management-oriented procurement as the most suitable procurement method for steel building construction in Sri Lanka.

Practical implications

The systematic procedure of procurement method selection for steel building construction may use in the Sri Lankan construction industry to limit the resource loss due to wrong selection of procurement.

Originality/value

A study which critically and comprehensively presenting a procurement selection process for steel building construction is not recorded in Sri Lanka prior to this study.

Abstract

Purpose

Kaizen in construction is a new paradigm stemming out of lean production systems. Construction companies in developing economies, such as Nigeria, have a task to innovate to liquidate in certain cases. With the aid of kaizen, which encompasses the benefit of stakeholder relationship improvement and management, profitability enhancement and delivery of projects to satisfied clients, construction companies can realise expected growth. An exploration of the critical success factors (CSF) and associated drivers within the limits of the scope is essential. The paper aims to discuss these issues.

Design/methodology/approach

Exploratory factor analysis statistical tests categorised the CSF identified in the literature review section. A detailed sampling approach extracted 135 questionnaires under the five-point Likert scale format from a larger population in Nigeria. An exploration of important drivers and iteration of eigenvalues combined with asymptotic significance of the drivers provided the CSF and significant drivers.

Findings

Construction management function, operational efficiency, construction business ethics and construction cost management were the CSF established from the exploratory factor analysis tests. It was confirmed that kaizen can be adopted in Nigerian construction companies with reflections on the principal drivers for the CSF.

Research limitations/implications

The exploration of the CSF and drivers associated with kaizen implementation can be applied to other developing countries with considerations of implementation in terms of cost and time.

Originality/value

The identification of CSF provides ample opportunity for consideration of kaizen in construction companies. The findings of this study are a basis for investigations into cost and time implications of kaizen adoption in construction companies.

Abstract

Purpose

Infrastructure projects play a significant role in community development. Infrastructure consists of many subcategories such as roads, bridges, railways, airports, communication infrastructure and harbors. The expressway is an essential part of modern transportation infrastructure. Due to its span and complexity, expressway construction results in several environmental impacts comparatively higher than typical road construction. In that event, environmental sustainability assessment in expressway construction and determining environmental measures to address those impacts is essential. Therefore, this research intends to investigate the environmental measures applicable to expressway projects in Sri Lanka.

Design/methodology/approach

This study involves a comparative analysis of different environmental impacts validated through expert interviews. The data required to perform the analysis were extracted through expert interviews and the Battelle method.

Findings

The findings revealed the importance of environmental indicators for expressway projects in Sri Lanka by assigning weightages. The Construction Phase received the highest weightage among three themes indicating that the construction phase causes greater environmental impact in expressway construction. Furthermore, the Site Maintenance Plan and Tree Compensating received the highest weightages under indicators.

Originality/value

The study makes an original contribution through the identification of indicators that lead to the improvement of environmental sustainability in expressway projects in Sri Lanka. Furthermore, the use of the Battelle method within the context of measuring environmental sustainability of expressways projects in general — and within the context of Sri Lanka — is a novel research approach.

Abstract

Purpose

Development of effective disaster risk reduction (DRR) strategies for communities at risk of being affected by natural disasters is considered essential, especially in the wake of devastating disaster events reported worldwide. As part of a wider research study investigating community perspectives on existing and potential strategies for enhancing resilience to natural disasters, community perspectives on infrastructure and structural protection requirements were investigated. The paper aims to discuss these issues.

Design/methodology/approach

Patuakhali region in South-Western Bangladesh is a region significantly at risk of multiple natural hazards. In order to engage local communities and obtain their perspectives, focus group discussions were held with local community leaders and policy makers of at-risk communities in Patuakhali region, South-Western Bangladesh.

Findings

Infrastructure and structural protection requirements highlighted included multi-purpose cyclone shelters, permanent embankments and improved transport infrastructure. Much of the discussions of focus group interviews were focused on cyclone shelters and embankments, suggesting their critical importance in reducing disaster risk and also dependence of coastal communities on those two measures.

Originality/value

The research design adopted sought to answer the research questions raised and also to inform local policy makers on community perspectives. Local policy makers involved in DRR initiatives in the region were informed of community perspectives and requirements, thus contributing to community engagement in implementing DRR activities.

Abstract

Purpose

A comprehensive literature review was conducted to identify the lean principles and the challenges of building refurbishment. To have an in-depth investigation of the application of lean principles to address the challenges of refurbishment projects, ten expert interviews following a qualitative research approach were utilised in this research. Data were analysed using manual content analysis to derive the framework.

Design/methodology/approach

The refurbishment of buildings has attracted the attention of the present construction industry. However, uncertain project characteristics, information deficiency, limited space for construction activities and less stakeholder involvement make it complex. Since the lean concept effectively deals with complex and uncertain projects, this study focusses to investigate the application of lean principles to overcome the challenges of refurbishment projects in Sri Lanka by developing a framework.

Findings

It was found that the five main lean principles of customer value, value stream, value flow, pull and perfection are appropriate for building refurbishment projects in Sri Lanka. Precise identification of clients and end-users, value adding and non-value adding activities, interruptions and stakeholder communication chains, setting scope, examining the possible technologies and taking measures to deliver the exact product to ensure the successful application of lean principles for refurbishment projects. Further, 27 benefits of five lean principles were identified which can be used to address the 13 identified challenges of building refurbishment of projects. Finally, a framework has developed portraying the application of lean principles in building refurbishment.

Practical implications

The framework developed is beneficial for the building refurbishment project team to address the barriers of refurbishment projects by applying lean principles.

Originality/value

This framework can be used as a guideline for the implementation of building refurbishment projects by addressing their challenges with lean principles.

Abstract

Purpose

Most developing countries, such as Sri Lanka (SL), are now looking for the support of foreign construction companies for large-scale infrastructure projects in return for expertise and resources. Thus, foreign companies may enter into agreements with local contractors through joint ventures (JVs). However, the priorities of construction project stakeholders may differ, which may ultimately end up in conflicts. Therefore, this research aims to investigate the most suitable conflict management strategies for international construction JVs (ICJVs) considering the SL context.

Design/methodology/approach

The mixed method was used for the research choice by selecting a questionnaire survey and expert interviews. Completed questionnaires (n = 78) were analysed using statistical techniques. The expert interviews with six industry practitioners were piloted to increase the validity and credibility of survey findings through a triangulation process where the collected data was analysed through content analysis.

Findings

The findings confirm that JV parties should first seek collaborative solutions in a conflict and seek legal redress only when those efforts are unsuccessful. Collaborating and compromising were recommended as the most appropriate tactics if an informal approach to conflict management was chosen. Alternative dispute resolution and litigation were identified as formal conflict management strategies.

Originality/value

This study, to the best of the authors’ knowledge, will be the first of its kind in SL, which will lead to a better understanding of conflict management in IJCVs and will encourage other researchers to extend this study through further work.

Abstract

Purpose

Lack of competition in procurement processes may affect the sustainable procurement due to overpriced and low-quality infrastructure. The purpose of this paper is to investigate the current practices in Malaysian public-private partnership (PPP) in handling unsolicited proposals within PPP and to suggest ways in which the practices can be improved to achieve sustainability.

Design/methodology/approach

Case study was conducted within which 13 semi-structured interviews were carried out with different groups: the policy makers, the practitioners and the experts. The study also scrutinised published guidelines and relevant regulations used by in management of unsolicited proposals in Malaysian PPP.

Findings

The Government of Malaysia welcomes unsolicited proposals from the private sector, even though it does not publish any established mechanisms to handle such proposals. Lack of competition in unsolicited proposals is a major concern in achieving sustainable goals of procurement. This could be addressed by introducing a competitive element to unsolicited proposals.

Originality/value

There are limited study and reports on the implementation of unsolicited proposals by the Malaysian Government. Besides adding to the literature, this paper reveals the management of unsolicited proposals. Most importantly, it is useful in assisting potential Malaysian PPP stakeholders and investors in what to expect, based on findings from the actual practice.

Abstract

Purpose

Climate change mitigation and adaptation play an important role in overcoming the climate change challenges facing Sri Lanka today. Many initiatives have been undertaken to implement different policies and plans in this regard, which require considerable mobilisation of national and international financing. In acquiring climate finance, many barriers can be identified. This paper aims to investigate such barriers to climate financing in Sri Lanka and proposes strategies to address them.

Design/methodology/approach

The qualitative research approach was undertaken in this study by conducting ten semi-structured interviews with experts who are involved in climate change policy implementation activities in Sri Lanka. The collected data were analysed using the content analysis method via Nvivo software.

Findings

The empirical findings unveil six key barriers and the corresponding root causes to climate financing in Sri Lanka. Inadequate domestic funding for climate actions was captured as the dominant barrier in this direction. This study also revealed that barriers and their root causes are interconnected, leading to many financial limitations in implementing climate actions. The importance of playing a leading role by the government and enabling an integrated approach between the private and public sector organisations were identified as key strategies to combat climate finance barriers.

Originality/value

Despite there being studies focusing on climate change and related policies, limited research has been carried out with regard to climate financing. Within this context, this study makes an original contribution in the area of climate financing with particular reference to a developing country like Sri Lanka. Further, the identification of barriers to climate financing, their root causes and strategies to address them also provides an original contribution to theory and practice.
