Abstract
Purpose
Facilitating the information exchange and interoperability between stakeholders during the life-cycle of an asset can be one of the fundamental necessities for developing an enhanced information exchange framework. Such a framework can also improve the successful accomplishment of building projects. This paper aims to use Semantic Web technologies for facilitating information exchange within existing building projects.
Design/methodology/approach
In real-world building projects, the construction industry’s information supply chain may initiate from near scratch when new building projects are started resulting in diverse data structures represented in unstructured data sources, like Excel spreadsheets and documents. Large-scale data generated throughout a building's life-cycle requires exchanging and processing during an asset's Operation and Maintenance (O&M) phase. Building information modelling (BIM) processes and related technologies can address some of the challenges and limitations of information exchange and interoperability within new building projects. However, the use of BIM in existing and retrofit assets has been hampered by the challenges surrounding the limitations of existing technologies.
Findings
The aim of this paper is twofold. Firstly, it briefly outlines the framework previously developed for generating semantically enriched 3D retrofit models. Secondly, a framework is proposed focussing on facilitating the information exchange and interoperability for existing buildings. Semantic Web technologies and standards, such as Web Ontology Language and existing AEC domain ontologies are used to enhance and improve the proposed framework.
Originality/value
The proposed framework is evaluated by implementing an example application and the Resource Description Framework data produced by the previously developed framework. The proposed approach makes a valuable contribution to the asset/facilities management (AM/FM) domain. It should be of interest to various FM practices for existing assets, such as the building information/knowledge management for design, construction and O&M stages of an asset’s life-cycle.

Abstract
Purpose
Mobile blended learning (MBL) is becoming common in higher education settings; however, the student’s intention to adopt such technological innovation is less explored. The purpose of this study is to measure MBL adoption using common variables used in the literature (supporting factors, learner attitude, learner perspective and learner effectiveness) and extending the model to include usability factors (ease of use, satisfaction and usefulness).
Design/methodology/approach
Data was collected from 322 respondents and analyzed using confirmatory factor analysis and partial least squares-structured equation modeling technique to assess the hypothesis. A five-point Likert scale instrument was developed using the existing literature for data collection.
Findings
The findings have both theoretical and managerial implications concerning MBL adoption. From a theoretical perspective, the findings provide a reconfirmation of the importance of usability in MBL adoption. From a managerial perspective, it will provide the necessary knowledge to incorporate relevant variables and factors that decision-makers could use to oversee a successful implementation.
Originality/value
This paper contributes to the ever-growing body of literature on MBL through an analysis of students’ intention to adopt MBL using usability factors.

Abstract
Purpose
Usability is one of the key concerns in the development of mobile learning applications. The aim of this paper is to design and validate a usability evaluation questionnaire (UEQ) for mobile learning applications.
Design/methodology/approach
The UEQ was developed in four stages: selecting primary studies and extracting usability problems, thematic analysis, creating UEQ items and validation and reliability using confirmatory factor analysis (CFA).
Findings
CFA to derive the model fit was computed using AMOS to test the construct validity. The model-fit values were within their respective expected acceptance levels. To assess the reliability of the instrument item loadings, the internal consistency coefficients such as Cronbach’s alpha, McDonald’s Omega and composite reliability were considered. Indicator loadings ranged between 0.735 and 0.933, fulfilling the threshold of above 0.7.
Originality/value
The study provides a novel UEQ for mobile learning applications, which can be used by developers and in academic research to assess mobile learning applications.

Abstract
Purpose
Traditional paper-based contracts are document-intensive, insecure, susceptible to forgery and errors, detrimental to productivity improvement and require multiple intermediaries. Addressing these challenges requires computerised construction to modernise the way modern construction projects are procured with blockchain-enabled smart contracts. Smart contracts could replace paper-based contracts by improving transparency and security and automating contractual terms, processes and transacting activities. However, smart contracts are an emerging technology with limited adoption in construction projects, and the issues influencing its widespread adoption remain unclear and unexplored. Hence, this study aims at exploring and understanding the important obstacles to adoption of smart contracts in construction projects.
Design/methodology/approach
Using an international questionnaire survey, the study draws on experienced construction practitioners with direct involvement and knowledge in blockchain technology and smart contract initiatives and activities. Descriptive statistics and fuzzy logic techniques were used to analyse and model the quantitative survey data to establish the critical barriers to smart contracts adoption.
Findings
Organisational and external characteristics, personal characteristics and technology characteristics constitute major obstacles to the successful adoption of smart contracts. Construction practitioners’ limited knowledge of smart contracts, resistance to technology change, insufficiently digitalised construction industry and lack of or weak governmental support are critical to smart contracts adoption.
Originality/value
The research contributes to the body of knowledge on diffusing cutting-edge technology by advancing the understanding of practitioners’ perspectives on the primary obstacles to smart contracts adoption. Understanding the obstacles provides industry stakeholders (policymakers, leaders and practitioners) with underpinning knowledge with which to develop and implement corrective actions.

Abstract
Purpose
The paper analyses the strategic management strategies of UK Construction Contracting Firms (CCFs) and their impact on the industry, highlighting their fragmentation, high-risk, low-profit nature and low profit returns. It suggests proactive strategies for sustainable growth and explores the potential of corporate diversification.
Design/methodology/approach
Utilising a thematic critical literature review, specific inclusion/exclusion criteria are used to select relevant literature together with a thematic qualitative synthesis data analysis approach to identify trends and challenges.
Findings
UK CCFs primarily use reactive and project-based strategic management, which may not align with long-term success due to market volatility, reactive supply, fragmentation, high competition and lack of differentiation. The short-term business cycle makes medium- to long-term strategy development difficult. It is recommended that CCFs adopt proactive strategic management and consider corporate diversification for enhanced competitiveness, stability and performance. Although there are conflicting findings on the impact of diversification on firm performance, this research suggests that it is a viable strategy for achieving enhanced firm performance and competitive advantage.
Research limitations/implications
The importance of proactive corporate strategies for CCFs is emphasised to overcome industry challenges, promote sustainable growth and enhance competitiveness. Corporate diversification, cultural transformation, management qualifications promotion and talent development collaboration are advocated, providing valuable insights for practitioners, policymakers and researchers.
Practical implications
The practical implications of this research involve fostering a shift towards proactive and dynamic strategic management in the UK construction industry, addressing the historical neglect of broader strategic perspectives and empowering practitioners and academics to drive positive change and innovation within the sector.
Social implications
The social implications of this research encompass the potential to enhance the overall efficiency, sustainability and collaborative dynamics within the UK construction industry, which can ultimately contribute to improved infrastructure development and the well-being of communities.
Originality/value
Project-driven strategic management in the UK construction industry is explored, questioning the reactive approach used by CCFs. It provides insights, best practices and improvement areas, emphasising diversification, proactive corporate strategies, cultural shifts and industry improvement, spanning theory, practice and theory.

Abstract
Purpose
The purpose of this paper is to provide a “trait based approach” for vendor selection and evaluation for expensive procurements in large businesses through a simple and easy‐to‐use mathematical model using safety, quality, delivery and cost criteria. Design/methodology/approach – We use 16 traits addressing safety (S), quality (Q), delivery (D) and cost (C) areas for evaluating performance of a vendor on a linear 10 point scale. We start with evaluating each “supplier‐supply item” combination and compute gross averages for each of the SQDC areas and finally arrive at an “Overall Performance Index” for each supplier‐supply item combination. These indices form a “Vendor Performance Dashboard” for decision making. Findings – The case study shows that the proposed method is quick and easy to adopt, and provides a logical framework for vendor selection and management, based on performance in the four critical (SQDC) areas. Research limitations/implications – A lot of monotonous computations are required for the proposed vendor evaluation process. Hence, the scope for software development warrants further investigation. There is also a need to develop a process for weighting the different SQDC elements for application in different industry/market contexts. Originality/value – This paper presents a unique and simple approach for generating dashboard data for decisions regarding evaluation of vendors and distribution of sub‐contracts in a dynamic technology intensive market with practical examples. The proposed model for vendor selection and determination of order sizes is less dependent on complex algorithms and more practical and logically framed than existing models.

Abstract
Purpose
Popularity in knowledge management has, unfortunately, not been matched by parallel empirical research on the processes, challenges and benefits of knowledge capture in small and medium enterprises (SMEs) in the construction industry, given the fact that 99 per cent of firms in the UK construction industry can be classified as SMEs. This paper aims to discuss the output of a research study, which is focused on knowledge capture in SMEs in construction industry. The paper also aims to present and discuss a computer‐based awareness tool on knowledge capture underpinned by Kolb's experiential learning theory.
Design/methodology/approach
The empirical study involved a total of 51 professionals from 26 SMEs in the construction industry. Grounded theory approach was adopted. Also, a content analysis was considered.
Findings
The results show that there is lack of awareness of complex issues associated with an effective knowledge capture process as well as ensuing benefits for SMEs in the construction industry. The effective implementation of knowledge capture in SMEs is partly dependent on the vision and flair of the owner/partners of the organisation. It is also determined by culture, structure, people, finance and technology, which warrants a coherent and structured approach.
Originality/value
A computer‐based awareness tool which is underpinned by Kolb's experiential learning theory.
