Survival challenges compel construction firms to change their business thinking on adapting business models (BMs). Unlike in the other fields, in the construction field, it is still a novel concept, probably because BM adaptation in the industry has not been sufficiently studied. Hence, the purpose of this study is to set a roadmap for the effective adaptation of the BM concept in the construction industry.

To develop a roadmap, this study analysed BM literature through a comprehensive literature review by finding the BM research development stages using studies done in other fields and locating construction industry BM literature.

No stage-wise development of BM research has taken place in the construction industry. The four BM research development stages, namely, defining BMs, listing BM components, describing BM components and modelling BM components as a business model ontology (BMO) in relation to the construction industry have to be followed for proper BM adaptation in the construction industry.

This study provided an overview of and a roadmap for BM adaptation in the construction industry for the benefit of future researchers. The proper adaptation of the BM concept through a BMO will enable construction business managers to easily innovate, design and change construction BMs to streamline their business thinking.

This paper aims to investigate the current practices and deficiencies in the legal and regulatory structure of public–private partnerships (PPPs) in Sri Lanka and explore recommended practices by international model laws and guidelines addressing such deficiencies.

Firstly, a desk study review was conducted to explore the current practices of PPP in Sri Lanka. Secondly, nine expert interviews were conducted to comprehend further current PPP practices and identify the deficiencies of legal and regulatory structure of PPP in Sri Lanka, and content analysis was used to analyse the interviews findings. Finally, international model laws and guidelines were reviewed to explore recommended best practices.

The research explored non-existence of a national PPP policy, lack of clarity of executing a project’s preliminary affordability, and lack of guidance on risk assessment and feasibility studies as current major deficiencies of PPP legal and regulatory structure in Sri Lanka. Further, findings showed that setting-up two project governance structures, a steering committee and a project team, and develop clear guidelines and standard forms can be adapted to strengthen the PPP legal and regulatory structure.

The findings of this study may be useful to policy makers in tracing essential reforms to PPP legal and regulatory structure. This study is limited to legal and regulatory structure of first three phases of the PPP project life cycle: project identification, project preparation and project procurement.

This paper establishes a novel framework to visualise the current practices and deficiencies in the PPP legal and regulatory framework in Sri Lanka, and the way of incorporating recommended practices by international model laws and guidelines for its future reformations.

Despite the desire to improve the sustainability of the construction industry, Sri Lanka is still plagued by the low-level adoption of essential methods such as Life Cycle Assessment (LCA) in building and infrastructure delivery. It is indispensable to investigate enablers for facilitating LCA because identification of enablers is a crucial step in the implementation of LCA. This study aims to analyze internal and external enablers for facilitating LCA for the Sri Lankan construction industry from the perspective of five stakeholder categories (academia, government, construction industry, society and environmentalists) and also aims to develop strategies to strengthen the enablers.

An explanatory research design was used. The five stakeholder categories identified above, whose contribution is essential for implementing LCA in Sri Lanka, were selected for data collection. A total of 20 semi-structured interviews were held representing each stakeholder category. The Repertory Grid Interview (RGI) technique was utilized and data analysis was performed using content analysis.

The results revealed that “ability to identify opportunities for environmental improvements as an extremely important internal enabler for all stakeholder categories” and “the positive growth in the country to achieve environmental sustainability”, “the availability of standardized LCA guides and handbooks” as extremely important external enablers for all stakeholder categories for facilitating LCA in the Sri Lankan construction industry. Further, strategies including making people aware of the LCA concept and development of the LCA database, etc. were proposed to strengthen the enablers.

Knowledge generated through this study would enable the abovementioned stakeholders to make informed decisions to promote the implementation of LCA in the Sri Lankan construction industry. Further, the results of this study have raised awareness of the issues that Sri Lanka will need to solve to expand the LCA applications.

So far, research on LCA has not looked into enablers that can facilitate the implementation of LCA in the Sri Lankan construction industry. This research provides a comprehensive view of the internal and external enablers for facilitating LCA from the perspective of five stakeholder categories and identifies enablers that led the abovementioned stakeholders to pursue the implementation of LCA in the Sri Lankan construction industry. The study also proposes strategies for strengthening the enablers.

Knowledge-based economies are popular in the present world. Simultaneously, universities are becoming more responsible for leading economic development through research. As a key contributor to the national economy, it is vital for the construction industry to move beyond outdated practices, and hence, reviewing the role of academic research in empowering the construction industry with knowledge is essential. The purpose of this paper is to focus on how relevant theories conceptualise the expected role of academic research in the innovative development of an industry and the specific location in the Sri Lankan construction industry.

Following a comprehensive literature review, empirical data were collected from the Sri Lankan context with a mixed approach informed by a pragmatist philosophical stance. The perspective of academia and industry practitioners were deductively obtained through surveys and inductively explored through qualitative interviews.

This study provides evidence that academic research in Sri Lanka does not contribute effectively to innovative construction management. Due to the absence of industry-focussed knowledge dissemination strategies, the academic–industry relationships are mostly non-research based. The industry lacks in research-informed-decision making, leading to lesser innovations.

The research conclusions are more applicable to the developing country construction industry contexts.

The research urges the need for improved academic–industry research collaborations and strategic knowledge dissemination movements.

The research confirms that academic research is a major integral part of the developing construction industry in a knowledge-based economy. In establishing the expected role of academic research, the research revealed the current practice to be under-located. Hence, the research prescribes the necessary actions; research collaborations in major and subsequent requirements.

The construction industry is often criticised due to inherited challenges: poor payment practices, inadequate collaboration, etc. Blockchain has the potential to address these issues with its salient features. Nonetheless, adopting blockchain and smart contracts (B&SC) within the construction industry is a comprehensive endeavour due to its intricate nature. The situation is bleak in Sri Lanka due to numerous barriers such as limited technical expertise, cost implications and many others. Hence, this paper aims to examine these barriers, appropriate strategies to overcome them, explore potential blockchain-applicable areas and formulate a framework to adopt B&SC in the construction industry of Sri Lanka (CISL).

This study employed a mixed research approach. The barriers for the adoption of B&SC to the CISL and their applicable areas were distinguished through a questionnaire survey and analysed using the Relative Importance Index. Strategies to overcome them were identified through expert interviews and analysed utilising manual-content analysis.

The study identified 15 barriers, 12 strategies and 9 areas for integrating B&SC for the CISL. The analysis indicated that having fewer blockchain-powered applications, the reluctance of the enterprises to bear costs to integrate blockchain and sluggish adaptation to new digital technologies are significant barriers. Further, conducting an industry-wide digitalisation analysis, developing an industry-wide digitalisation strategy and recruiting skilful IT staff were pointed out as the pivotal strategies. Moreover, payment and supply chain management were identified as areas with high potential.

This study unveils an analysis of barriers, strategies and areas in adopting B&SC for CISL and formulates a framework. It can be deployed as a guideline for implementing B&SC in the CISL.
