The innovation of technology, particularly Artificial Intelligence (AI), has rapidly changed the world. It is currently at a nascent stage worldwide in the construction industry throughout the lifecycle of projects. However, construction organisations of developing countries such as South Africa are still lagging in recognising the need to adopt emerging digital innovations such as AI to improve the built sector’s performance. This study aims to identify organisational factors imperative to driving the adoption of AI in construction organisations. The study uses a quantitative survey approach to collect data through snowball sampling of industry experts on factors associated with AI adoption. With data from 169 respondents, exploratory factor analysis was adopted to identify critical organisational factors to ease AI adoption in the industry. Furthermore, confirmatory factor analysis was employed to demonstrate the relationship among the constructs. The study proposes 17 factors to drive organisational AI, categorised into four components; innovative organisational culture, competence-based development, collaborative decision-making, and strategic analysis. However, previous studies have identified organisational factors of AI in the construction and allied industries. This study presented the organisational factors of AI in the construction industry using EFA and CFA, a method not used in articles presented in the SLR identified. The use of CFA improves the measurement of the constructs. It thus enhances understanding of the underlying components of a construct and its relationship with AI in the construction industry.
Introduction
Various productivity problems characterise the construction industry of developing countries. These include a shortage of skilled labour, low productivity, excessive material waste, and unsafe working conditions, primarily caused by repetitive and labour-intensive tasks (Pradhananga et al., 2021). Windapo and Cattell (2013) noted challenges of the construction industry of developing countries to include public sector capacity, lack of required skills, globalisation and technology, among others. These constraints reduce the efficiency of the construction process and provide difficult conditions for the country’s construction development (Ivanov and Aldeen, 2018). The construction industry is found to play a crucial role in developing economies worldwide (Isa et al., 2013). The government can laudably leverage it as a platform to stimulate the national economic transformation toward developed country status (Yap et al., 2019). The construction industry needs to adopt an efficient and effective solution to promote infrastructure development, develop the local economy, reduce costs, and increase construction efficiencies (Pheng and Hou, 2019). Moreover, the industry needs to improve service quality and expertise and attract increasing interest from policymakers, researchers, and industry practitioners (Alinaitwe and Ayesiga, 2013). This addresses the construction industry’s dealings with important data from diverse disciplines throughout a project’s life cycle (Yousif et al., 2021).
It is now a reality to develop construction processes and systems aimed at technological innovations that can successfully contribute to a building’s construction process (Diniz Fonseca, 2021). According to Sun et al. (2020), technology development drives the continuous transformation of the construction industry. The industry’s issues put it under greater pressure to shift from a sector that has rejected emerging technology to one that embraces it (El Jazzar et al., 2021). Olanipekun and Sutrisna (2021) noted that construction professionals, companies, and government agencies worldwide declared their preference for digital technologies in construction. Adopting technology such as AI comes with many advantages for the construction industry. These include visualisation, clear communication, site planning, logistics, health and safety management (Swallow and Zulu, 2019). However, the construction industry is lethargic in adopting technology that can address the challenges holistically (Nadhim et al., 2016; Delgado et al., 2019). Most technologies in the construction industry focus on a single task. Drones/UAVs are efficient and effective means of remotely conducting safety inspections in construction projects (Nnaji et al., 2019). 3D Concrete Printing technologies create objects by depositing concrete layer-by-layer using materials such as polymers or metals (Adaloudis and Bonnin Roca, 2021). Building Information Modelling (BIM) is used for design preparation, 3D modelling, simulation, risk assessment, environmental analysis, site control, project control, identification, and collision detection (Shehzad et al., 2021). These technologies provide part solutions to the problems of the construction industry. With this comes the usage of AI.
Artificial Intelligence has completely changed conventional design, manufacturing, and construction technologies (Manzoor et al., 2021). In construction, AI helps with operations on-site such as automated welding bricklaying and alerts an operator with a warning message, thereby minimising risks (Chakkravarthy, 2019). AI also automatically adds explicit information to models produced from algorithms trained to recognise and infer pre-defined groups of target concepts from building patterns (Sacks et al., 2020). It has ramifications in economics, geopolitics, sociology, the environment, demographics, and security, among other fields and disciplines (Yeh and Chen, 2018). AI has enabled rapid computing capabilities such as natural language processing, voice recognition, and machine learning (Sohn and Kwon, 2020). Natural language AI is used to cluster construction schedules (Hong et al., 2021). Voice recognition is used in building quantities software using text to speech (Olanrewaju et al., 2020). The application of machine learning in construction is in site supervision, automatic detection, and intelligent maintenance, among others (Xu et al., 2021). AI is defined as being the oldest field of computer science and very broad, dealing with all aspects of mimicking cognitive functions for real-world problem solving and building systems that learn and think like people (Holzinger et al., 2019). AI plays a significant role in the construction industry in terms of digitisation and intelligence (Abioye et al., 2021). It enables significant automation, performance, and reliability improvements and directly links physical and digital in other industries (Manzoor et al., 2021). On the other hand, construction organisations have yet to establish common AI adoption infrastructures (Mahroof, 2019). Furthermore, stakeholders in the construction industry are apprehensive of AI technology’s market worth (Merschbrock and Munkvold, 2015). The application of AI can improve construction development competence by facilitating data exchange (Lekan et al., 2018).
The need to use digital technologies is to improve the productivity and performance of the built environment in developing countries such as South Africa (Windapo, 2021). South Africa needs infrastructure to drive economic growth, but this depends on the built environment performing optimally and being productive (Li et al., 2019). AI has been at the forefront of research for operations and supply chain management (Dubey et al., 2019). However, organisations are limited in resources and capabilities (Girginkaya Akdag and Maqsood, 2019). This is because organisations play an important role in external shocks like pandemics or geopolitical situations; adapting to market changes or responding to customer demands is critical in AI adoption (Paul et al., 2020). According to Mabad et al. (2021), organisations are not considering technological advancement and AI implementation to diminish their capabilities and efficiencies in service provision in the current digitalisation age.
The construction industry’s productivity depends on the smooth integration of applicable AI technology. This is because it restructured organisations by making their business processes more productive and efficient than ever before (Lakhwani et al., 2020). According to Miranda et al. (2016), organisations frequently overlook the development of learning and innovation, despite these two qualities being critical in the search for long-term sustainability in the construction industry and market. Moreover, organisations in the construction industry undergo many changes such as merging and acquisition, cultural and structural, procedural (Sarala et al., 2019; Boadu et al., 2020). Organisational adoption is critical because it involves technology infrastructure, expertise (human) resources, and organisational commitment to change (Saghafian et al., 2021). While organisational perspectives are not often ignored or even denied in the technological factors. The results are a major factor that causes swing from either to or from the technology imperative of considering the organisation (Metcalf and Benn, 2012). In a changing context, AI adoption in organisations is dynamically and jointly created, affecting the intra-organisational legitimacy of technology in the adoptive organisation and, as a result, affecting the periodic adoption results (Ren, 2019). Moreover, construction organisations come in different sizes, either large or SMEs. This portends that there could be disenfranchisement in the process; hence an inclusive strategy can examine how all these concerns can be easily resolved.
Previous studies have looked at AI adoption in the construction industry. For instance, Mohamed et al. (2021) looked at the implementation of AI in the Malaysian construction industry. The study looked at AI to improve project quality while reducing project duration, cost, and design by utilizing technologies in the construction sector. Furthermore, Nikolaeva and Nikolenko’s research, 2021) aimed to analyse and pick ready-made solutions for the use of AI technology to improve a construction company’s productivity in the chosen AI activity. Similarly, Karan et al. (2020) investigated the use of AI as a tool in the AEC business, with decisions made on data input. Hooda et al. (2021) focused on how AI and its many concepts can be integrated with developing fields of structural engineering and how it influences the construction industry by employing in the primary areas of structural health assessment damages and construction management. Consequently, it becomes difficult for construction organisations to adopt AI as they are not driven or prohibited by any factor.
Systematic literature review conducted for providing literature evidence for organisational factors in the construction and allied industries. Jöhnk et al. (2020) looked at AI readiness factors in organisations using the qualitative interview research method. Chatterjee et al. (2020) looked at the adoption of AI in Indian organisations using partial least square (PLS)—structural equation modelling (SEM). García de Soto et al. (2019) looked at AI-related technologies’ implications on construction organisational structures. The study used a case study to address the implications. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were not used in the review to derive estimates of factor structure when there was a priori information available that could help identify factors (Faragher, 2005). A valuable analysis for validating data structure is combining the experimental methods such as EFA and CFA (Hyett and Parker, 2014).
To date, there are no empirical studies on AI in the construction industry of South Africa. As a result, the current situation of AI adoption factors in South African construction organisations remains unclear. For this reason, the research question concerning organisational factors of AI adoption in the South African construction industry remains unclear. Thus, posing the research question “What are the organisational factors of AI in the South African construction industry?’ aims to fill the research gap. This research question should provide South African construction organisations with practical assistance in AI implementation. Further, this study aims to identify the AI constructs and then test the relationship between the constructs.
The paper starts with an introduction and background to the study’s structure. This is followed by a literature review of the definition and scope of AI in the construction industry. After the presentation on the research method, the results are discussed before conclusions are made, and recommendations are proposed.
Literature Review
Definition and Scope of Artificial Intelligence
Scholars define AI as the ability to make sense of data gathered from previous experiences and deal with the uncertainty of future actions. AI simulates human-like cognitive activities more transparently (Trocin et al., 2021). In recent years, AI has been broadly defined as the study and design of intelligent agents, with the ultimate objective of making computers capable of thinking and acting (Smith, 2016; Shneiderman, 2020). AI aims to solve jobs that are difficult to formalise but relatively simple for humans with intuitive abilities (Shi et al., 2020). Advances in AI and big data analytics have made it possible to use numerous forms of data, make data-driven decisions, and improve operational efficiency. IT-enabled data collection and analysis skills have improved the management of organisations (Cho and Wang, 2021).
Artificial Intelligence in Construction Organisations
AI is a swiftly developing field with robots impacting how organisations are run and managed. It has attracted an important place in recent years. With the help of the technologies such as machine learning (ML), autonomous tools can promote their concert by deriving from the data over time (Dhanabalan and Sathish, 2018). According to Dhamija and Bag (2020), AI is the key to achieving persuasive operational transformations in most current organisational set-ups. According to Arrotéia et al. (2021), AI has become a common process tool for managing construction projects and organisations. This is because it consists of all aspects, disciplines, and systems of a facility within a model, with which all stakeholders can collaborate more accurately and efficiently than traditional processes (Azhar et al., 2015). Organisations view AI as capable of performing jobs that formerly required the human mind. In terms of application, adoption, processing speed, and capacities, AI-based systems quickly evolve (Haefner et al., 2021). AI has brought about capabilities within the construction sector through technical skills and social skills to deliver project outcomes (Sima et al., 2020). These capabilities result from the organisation’s AI investments in staffing, training, compensation, communication, and other human resource areas (Ahuja et al., 2018). The machines are increasingly capable of taking on less-routine tasks (Ghosh et al., 2018). Digital technologies, such as AI cause major changes in the features of an organisation, a process known as digital transformation. As a result, AI has become a topic of interest in strategic information research and industrial business practice (Wu et al., 2021). However, human intellect does not rule out the possibility of making a perfect decision at the right time. AI is simply about ‘choosing’ the best option at the right time.
Factors that could influence the adoption of AI in organisations have been identified in various studies. Ghobakhloo and Ching (2019) study identified that knowledge and competency and information processing management are the factors of organisational AI adoption. Automation, the creation of networks of connected and intelligent machines and materials, and the integration of real and virtual worlds are all associated with AI. Employees must therefore be knowledgeable and competent in the disciplines of IDT, cybernetics, and data analytics, implying that skilled employees must also undergo skill evolution. In the construction sector, AI plays a vital role as a major enabler of information processing capability to process increased data. As a result, organisations with a greater demand for information processing are projected to be more open to AI adoption. Turner et al. (2020) indicated that performance, cost, government pressure and knowledge are key organisational factors influencing AI adoption. AI can customise part production and utilise it to enable new cost-effective building methods. It reduces workers’ exposure to risks encountered in conventional construction projects and overall reduces construction costs. Likewsie, Mabad et al., 2021) study showed that productivity, government pressure and firm size are important. Governments can use their regulatory frameworks to favour or inhibit AI adoption. When deciding whether to implement new technology, construction organisations consider various regulations, norms, and guidelines. Governments can use their regulatory frameworks to favour or inhibit AI adoption. When deciding whether to implement new technology, construction organisations consider various regulations, norms, and guidelines.
Jöhnk et al. (2020) found organisational readiness, top management support, decision making support, cost, skills, and attitude to innovation. An informed decision regarding an organisation’s readiness increases the probability of successful AI adoption and is important to successfully leverage AI’s business value. Instead of depending on “gut feeling or business instinct,” decision-making is the technique of employing insights based on data analytics to make decisions. AI-assisted decision-making not only improves organisational performance but also raises AI readiness because it serves as a warm-up for AI-driven decision-making. As a result, organisations should promote decision-making as an organisational practice and prepare employees to work in a culture where AI provides complementary insights to help organisations make better judgements. The willingness of top management to start AI efforts from the top down and express support for bottom-up initiatives is referred to as top management support. Top management support is critical for successful AI adoption, given the vast range of organisational requirements connected with AI implementation. Experts underlined that a firm could only commit to AI adoption if top management has given the green light. Integrating AI adoption into strategy and cultivating AI expertise and awareness are strong top management support indications. Moreover, organisations recognise needs, become aware of innovation, form an attitude toward it, and create a proposal for adoption. García de Soto et al. (2019) looked at the implications of AI in the construction industry, workforce and organisations. They revealed that time-saving, cost, competitive pressure and collaboration influence AI adoption. Currently, construction organisations and roles need to be transformed in many aspects. These include reducing lead times and improved quality and cost by integrating design and construction activities and maximising parallelism in AI technologies’ working practices. Moreover, constructions adopt AI to ensure competitiveness. The construction industry must adopt a new organisation involving collaboration and interaction between the different construction professionals.
McAleenan (2020) further identified risk, standards and decision making support. Government, industry bodies and organisations develop are among many who are researching and producing guidelines for system designers and developers. This is to recognise that technological developments occur faster than philosophical and ethical considerations can keep up. Unlimited risks such as corruption, fragmented structures, inefficient design, and insufficient planning time drive organisations to adopt AI. While Chatterjee et al. (2020) pointed out cost, work culture, staff relationship, and attitude towards innovation. The AI system causes organisations to shift their attention away from traditional thinking about cutting operation costs and increasing profit. It is extremely difficult for humans to manage and evaluate such a large of data cost-effectively, necessitating the use of AI technology. Users, who are employees of organisations, wish to utilise a system if it is useful and believes that utilising it would provide them with delight and beauty. This is how they feel about the organisation’s innovation.
Olawumi and Chan (2020) and Pan and Pan (2020) added that collaboration, government pressure, standards, top management support, firm size and organisational readiness are key influencers on an organisation’s AI adoption. Organisations need to secure project stakeholders’ collaboration and coordination and early involvement in construction projects. As a result, construction organisations must avoid using traditional procedures. Regulatory policies and standards could facilitate innovation adoption by reward schemes or mandatory regulations. In construction organisations, the government’s role is critical for innovation adoption to formulate regulation and guidance for the largest client. Table 1 below shows the summary of organisational factors.
TABLE 1. Summary of organisational factors.
Research Method
The research techniques chosen for this study were a literature review accompanied by a quantitative survey to achieve the study’s objectives. A quantitative research approach tests objective theories, formulating facts, uncovering patterns, examining the relationship between statistically measured variables and analysing them using statistical techniques (Apuke, 2017). A quantitative approach was adopted as it enables the development of quantitative valuation indicators (Basias and Pollalis, 2018). The questionnaire technique was chosen for this survey because it was rapid, allowed for broad geographic coverage, and provided adequate opportunity for respondents to check facts and provide accurate replies (Jones et al., 2013). In addition, questionnaires are cost-effective. They can provide a significant number of research data for a relatively low cost in terms of materials, money, and time, and they are reasonably simple to set up (Datti et al., 2019). The research followed the process depicted in Figure 1—literature review, questionnaire survey, data analysis using SPSS 27 (mean item score (MIS), exploratory factor analysis (EFA)) and SPSS AMOS 27 of all the constructs that emerged during the study.
FIGURE 1. The research process of the study.
Literature Review
The first step was to perform a literature review to identify key factors affecting the construction industry’s AI Organisational factors. A systematic literature review (SLR) was conducted. This literature method was chosen as its systematic literature review provides transparent and explicit protocols. Researchers use the search for and assess the field of studies relevant to a specific research topic, in this case being organisational factors of AI in the construction industry (Tian et al., 2018).
Review Protocol
The first stage of SLR is to establish a review protocol. This entails formulating good and comprehensive research questions, strategising systematic searching efforts, selecting appropriate inclusion criteria, implementing a rigorous quality appraisal process, strategising data extraction and synthesis, and demonstrating the best data from their review. A review protocol can help guide and ensure that the researcher stays on course while also increasing the review’s methodological transparency (Shaffril et al., 2020).
The following research question was proposed in this paper: What are the organisational factors of AI adoption in the construction industry?
Various steps were undertaken to ensure the research question was answered. The established protocol comprised information on the research question, sample articles, search strategy and selecting relevant keywords to characterise the scope of the study (de Carvalho et al., 2017). This includes the assessment of inclusion and exclusion criteria (de Melo et al., 2020).
Defining an Inclusion and Exclusion Criteria
This review’s inclusion criteria were empirical studies based on the relevant research topic, organisational factors of AI adoption in the construction and allied industries, written in English and published between 2011 and 2021. Only papers published in journals and peer-reviewed conferences were included. Ensuring the correct data was being extracted and avoiding any effort at biased results of any specific type is extremely important (Wager and Wiffen, 2011). To eliminate this risk and increase the validity of the findings, the exclusion criteria eliminated papers, not in the scope of the industries, years, language, and publication type.
Search for Studies
When searching for the relevant documents, various search terms were used. These search terms include 4IR, Adoption, Artificial Intelligence, Automation, Construction industry, Construction Innovation Construction 4.0, Digitalisation, Factors, Machine Learning, Organisations, Organisations, Organisational, Robotics, Fourth industrial revolution. Furthermore, Boolean and database-specific operators such as AND, OR and special characters such as truncation (*) or (?) were associated with the search terms were used (Madigan et al., 2014).
Select Studies for Inclusion Based on Pre-Defined Criteria
Studies were discovered through searching these electronic databases: ASCE Journals, Emerald Insight, Elsevier ScienceDirect, Engineering Village, Google Scholar, ICE virtual library, IOPscience, IEEE Xplore, Elsevier ScienceDirect, Elsevier Scopus, SpringerLink and Taylor and Francis
Extract Data From Studies Included
Relevant information was screened after the article extraction, eliminating the need to read all the papers thoroughly. The ATLAS. ti 9 was utilised to systematically sort and conduct the theme analysis review of the final articles (Samsudin et al., 2022). The findings were used to develop a questionnaire for the South African Construction professionals to get primary data. Table 1 presents a list of seventeen organisational aspects of AI adoption in the construction industry culled from the literature review.
Data Collection
A questionnaire was designed to solicit the perceptions of construction professionals in the Gauteng Province of South Africa. The purpose of selecting the province of Gauteng is that it is the Republic of South Africa’s economic powerhouse and makes the largest contribution to almost 38 per cent, KwaZulu-Natal (KZN) at 14.9 per cent compared to second place. Although it is the smallest province, with 12.2 million people, it is the most highly populated, representing nearly 25 per cent of the national total. It is also the fastest-growing province in the country, with a population growth of more than 33% between 1996 and 2011 (Hove and Banjo, 2018).
Questionnaires have become a vital tool for declarations about specific groups or individuals or entire populations when properly constructed and responsibly administered (Roopa and Rani, 2012). This is a valuable method of gathering a wide range of information from many individuals, often called respondents. An online questionnaire using Google form was administered between December 2020 and January 2021. The questionnaire looked at respondents’ demographics and organisational factors of AI adoption. It used a five-point Likert scale from 1 (“strongly disagree”) to 5 (“strongly agree”), with three being classed as ‘neutral’. The scale was adopted due to its ability to detect respondents’ feelings about their attitudes (Munyasya and Chileshe, 2018).
Judgemental and snowball sampling methods targeted professionals from professional networks such as industry practitioners. It was also incorporated on social messaging platforms such as LinkedIn and mails to reach out to participants within the study area. The social media platforms comprise communication websites that facilitate relationship forming between users from diverse backgrounds, resulting in a rich social structure of construction professionals (Kapoor et al., 2017).
The judgemental sampling technique does not allow the researcher to generalise to the population because it does not randomly sample research participants. To have the necessary information and be willing to share it, the research needs to concentrate on those individuals with the same opinion (Etikan and Bala, 2017). Snowball sampling is a non-random method of selection that uses a few cases to encourage the participation of other cases in the study, thus increasing the sample size (Taherdoost, 2016). Initial contacts between the initial respondents and the researcher are done with a small group of individuals relevant to the research topic and then used to establish connections with others. It is a helpful way to build networks and increase participants’ numbers by asking each participant to suggest more potential participants. The non-probability sampling methods were appropriate as a random sampling method could not be used to select respondents from the population identified from LinkedIn (Lehdonvirta et al., 2020). The respondents can rather be selected based on their willingness to participate in the research study and their knowledge of construction processes (Darko and Chan, 2018).
A total of 150 respondents were targeted for this study, three times above the minimum requirement based on de Winter et al. (2009) and Pearson and Mundform (2010). One hundred sixty-nine 169) completed questionnaires were received and used for analysis at the end of the data collection period. The respondents comprised Architects, Quantity Surveyors, Civil Engineers, Construction Managers, and Construction Project Managers.
Data Analysis
The data were analysed using descriptive and inferential statistics. The outputs were mean and principal components. The analyses were conducted using the Statistical Package for the Social Sciences (SPSS) version 27 and SPSS AMOS (Analysis of a Moment Structures) version 27.
Mean Item Score
The primary responses from participants were analysed using the Mean Item Score (MIS). The average agreement among respondents about the organisational elements influencing AI adoption in the South African construction industry is represented by MIS (Sarhan et al., 2018). To summarise the characteristics of the respondents and the current status of AI applications in construction sector organisations, descriptive statistics were employed to measure central tendency and dispersion (Nasila and Cloete, 2018). The arithmetic mean is a measure of central tendency that represents the average values of a group of numbers. Standard deviation (SD) is a quantitative measure of how much each result deviates from the mean. It is a metric for determining something is (Evans et al., 2021). A low SD suggests that the values are close to the mean, whereas a high SD indicates that the data points span a wide range of values. To rank the highest to lowest mean, the MIS was employed (Ejohwomu et al., 2017). The Likert scale is used to determine the rankings.
Exploratory Factor Analysis
Exploratory factor analysis (EFA) is a computational technique for determining the structure that underpins many variables (Ngowtanasuwan 2019:6). EFA filters out the variables that are not important, leaving just the description variables. Before the EFA, Kaiser-Meyer-Olkin (KMO) and Bartlett’s sphericity tests were used to assess sampling adequacy. This is needed to check the case-to-variable ratio and thus the factorability of the data. Bartlett’s test of sphericity should be significant at (p < 0.05) for the factor analysis to be appropriate (Ul Hadia et al., 2016). The KMO scale runs from 0 to 1, but anything above 0.45 is considered appropriate (Zeray et al., 2021). The total variance explained was also examined as an extraction process of items to reduce them into a manageable number before further analysis (Effendi et al., 2020). Objects with eigenvalues greater than 1.0 are separated into different components using this method (Matsunaga, 2010). The rotated variable matrix was also analysed, and only objects with a factor loading of greater than 0.5 were held for further analysis (Maskey et al., 2018).
Confirmatory Factor Analysis
This research uses the Confirmatory Factor Analysis (CFA) to test for convergent validity and to measure the measurement model’s adequacy (Maletičet al., 2013). It also demonstrated the relationship among the constructs. The results from the EFA were used in the CFA to verify the validity of the latent variables and the measurement variables using the SPSS AMOS 27 statistical program (Kim et al., 2015). According to Zahoor et al. (2017), a sample size of 200 can guarantee reliable results if the data set is analysed using confirmatory factor analysis (CFA). However, Kyriazos (2018) claims that for a CFA model with 3–4 indicators per component, a sample size of more than 100 is required. The many fit indices in CFA should be reported since distinct fit indices indicate different aspects of fit. Numerous goodness-of-fit indices typically used in CFA and suggested literature were applied (Chan et al., 2017). As stated in Table 2, the study used the fit indices adopted by Chan et al. (2014), Molwus et al. (2017), Tanko et al. (2017), Zahoor et al. (2017), and Puiu (2020).
TABLE 2. Model fit indices.
Validity and Reliability
Reliability means that the score of an instrument is stable and coherent. When the instrument is repeatedly administered at different times, the scores should remain the same and remain consistent (Creswell and Guetterman, 2019). The Likert scale was reliable for this study as the little variance is specific to particular items. On the other hand, validity implies that individual instrument scores are meaningful and allow the researcher to draw reasonable conclusions from the studied sample population. Internal validity was used to see how accurately the measures obtained from the research quantified what it was designed to measure. The internal reliability was measured using the most common internal consistency measure being measured is Cronbach’s alpha (α) (Mohajan, 2017). Cronbach’s alpha measures the internal consistency of items, that is, how closely related a set of items are as a group, usually interpreted as the mean of all possible split-half coefficients. (Sileyew, 2019). It is viewed as the most appropriate measure of reliability when using Likert scales. If Cronbach’s alpha coefficient is close to 1, the construct is considered internally consistent and highly reliable (Liu et al., 2021). However, most scholars agree that the minimum Cronbach Alpha coefficient is 0.70 (Nair et al., 2019).
Ethical Considerations
In addition to choosing the right research methodology and procedures, ethical considerations should be considered when performing the research. It is critical to think about the fundamentals of ethical human-participant research in more depth (Fleming and Zegwaard, 2018). The University of Johannesburg granted ethical approval for this research. The research ethics addressed beneficence, nonmaleficence, autonomy and justice. Under the principle of beneficence, researchers must also protect participants from exploitation. Any information provided by participants through their study involvement must be protected (Barrow et al., 2021). The study’s benefit was also explained as AI can reduce human errors and increase productivity on construction projects. Autonomy also referred to as respect for persons, is a fundamental ethical principle that guides the research on construction professionals. The principle obligates the researcher to allow participants the freedom to decide whether to take part in the research or not (Singh and Hylton, 2015). In the research context, nonmaleficence compels the researcher to avoid the accidental or intentional infliction of harm and to minimise the risk of harm or discomfort for research subjects (Sobočan et al., 2018). Justice demands an equitable selection of research participants. This means avoiding research participant populations that may be unfairly coerced into participating (Žydžiūnaitė, 2018). The study participants were construction professionals, including project managers, quantity surveyors, architects, and civil engineers working in construction projects from public and private organisations in Gauteng, South Africa. All races and groups were involved in the study; no single race will be the target and the other left out of the survey.

Organisational Factors Influencing AI Adoption
Descriptive Results
A descriptive analysis of the study participants’ responses to the questionnaire items is presented below in Table 4 on organisational factors of AI adoption in the South African construction industry. Overall, all the 17 identified organisational factors to AI adoption have MIS >3.50. The organisational factor with the highest MIS is top management skills (M = 4.02), followed by decision making support (M = 3.09) and cost to the organisation (MIS = 3.98). The lowest MIS scores came from risks involved in using innovative technologies (MIS = 3.61), the reputation of the organisation (MIS = 3.60) and firm size (M = 3.57), an important factor in AI adoption.

The KMO measure of sampling adequacy was at the value of 0.895. This is greater than the adequate value of 0.70. This result indicates that multicollinearity structures among the variables were sufficient to justify aggregating the organisational factors. This is into the related sets for extraction of exploratory factor analysis Bartlett’s Test of Sphericity was significant at p < 0.001. This indicates that the data on organisational factors of AI adoption can be used for factor analysis. This is shown in Table 5 below.
TABLE 5. KMO and Bartlett’s test.
As shown in Table 6, principal components were extracted using initial eigenvalues greater than 1. The analysis revealed four components as the number of factors for this particular EFA, with the explained variance percentage value of 62.43%. Component one was 41.747%, component 2 was 7.760%, component 3 was 6.852%, and component 4 was 6.070%. This is shown in Table 6 below.
TABLE 6. Total variance explained.
Table 7 presents the results of EFA for the organisational factors identified for the adoption of AI by South African construction professionals, separated into four principal component groups. The organisation’s work culture explains component one, the workplace relationship among staff, cost to organisation, organisational readiness, standards and organisation attitude to innovation. Component 2 is explained by competitive pressure, information Processing Management, firm size knowledge and competency and government pressure. Component three is explained by top management skills, decision making support and collaboration. Lastly, component four is explained by improved performance, risks involved in using AI technologies and time-saving.

Confirmatory Factor Analysis
In the confirmatory factor analysis, the output revealed slightly good scores for a good fit in terms of fit indices. The Chi-square value is at 311.47 at a p < 0.001. The degree of freedom is 91 ratios of CMIN/df 3.42. The Root Means Square Error of Approximation (RMSEA) value of 0.12 and Root mean sq. residual (RMR) value of 0.072 indicates that the model cannot be rejected at a high confidence level. Furthermore, all other essential indices such as goodness-of-fit index (GFI = ), comparative fit index (CFI = 0.766), Tucker-Lewis index (TLI = 0.781), and incremental fit index (IFI = 0.838) values provide evidence that the fit between the measurement model and the data is certainly acceptable. This is shown in Table 8 below.
TABLE 8. Fit indices.
The performed model revealed that the four components positively influence organisational AI adoption and that the influence is statistically significant. This is shown in table 9 below.

Discussion
Descriptive Results
From the descriptive statistics, top management skills (x̄ = 4.02, SD = 0.92, IQR = 4.00), decision making support (x̄ = 3.99, SD = 0.81, IQR = 4.00) and cost to organisation (x̄ = 3.98, SD = 0.99, IQR = 4.00) are the top three highest-ranked in the descriptive analysis ranked highest in the descriptive analysis. However, risks involved in using innovative technologies (x̄ = 3.61, SD = 1.10, IQR = 4.00), the reputation of the organisation (x̄ = 3.60, SD = 1.08, IQR = 4.00) and firm size (x̄ = 3.57, SD = 1.11, IQR = 4.00) were the least ranked variables.
This supports the findings of Jöhnk et al. (2020). Top management support is a priority in implementing AI in organisations. Managers who gain the essential knowledge and abilities create a favourable environment for adopting and executing innovation. Managers are required, in particular, to be able to gather information on the best competition and learn how they succeed in adopting innovation. Competitive intelligence can assist managers in making decisions about whether innovations are less risky or difficult and will have the greatest influence on the company’s industry reputation and profitability (Yusof et al., 2014). This also supports the findings of McAleenan (2020) when it comes to decision making support. Much time is spent on risk management techniques, as the consequences of making a poor decision and replacing a poor technology may be significant, resulting in a significant delay and huge additional costs to the organisation (Sepasgozar et al., 2018). The findings also support Chatterjee et al. (2020) and Pan and Pan (2020) regarding cost. However, the findings do not support Olawumi and Chan (2020). This is because the initial cost of AI set up in the organisation is expensive. According to Bello et al. (2020), AI technologies have provided construction organisations with access to high-end computing infrastructure and applications that could cost a fortune to acquire. However, it will result in a lower total cost of project delivery, in the long run, offering construction businesses a competitive and operational advantage.
The findings do not support McAleenan’s (2020) when it comes to risks. In Africa, the more diffused a certain technology in the construction industry, the less risky it is to implement. That can influence industrial practitioners’ interest in the technology (Darko et al., 2017). Furthermore, the findings on reputation do not collaborate with those of García de Soto et al. (2019). Construction organisations need to preserve the image and reputation they have. The adoption of AI not only helps with the record-keeping of information. It also avoids bad publicity, which may strain the relationship with stakeholders (van Heerden et al., 2018). The findings for firm size support those of Pan and Pan (2020). Because both small and large organisations have certain innovation generation and adoption advantages, firm size has no bearing on innovation orientation. As a result, the size of an organisation is a poor predictor of AI activities (Kamal et al., 2016).
In order to understand the organisational factors of AI in the South African construction industry, exploratory factor analysis was undertaken. The 17 variables were factored into four clusters, which then underwent confirmatory factor analysis to demonstrate the relationship among the constructs. Figure 2 below shows the diagrammatic representation of the organisational factors according to EFA.
FIGURE 2. Diagrammatic representation of the organisational factors.
Component 1 - Innovative Organisational Culture
This component has six sub-components, mainly the organisation’s work culture (0.781), the workplace relationship among staff (0.704), the cost to the organisation (0.697), organisational readiness (0.681), standards (0.515) and organisation attitude to innovation (0488). This cluster accounts for 41.747% of the variance, as shown in Table. This component was significant at a p-value of 0.001 at a path coefficient of 0.239.
The findings do not support Olawumi and Chan’s (2020). The findings suggest that innovation can flow in organisations when organisational culture supports it. Focus shifts from traditional processes to AI technology created through organisational routines, practices, norms, and cultures. It suggests that organisational culture changes are needed before AI can be successfully embedded within construction practices (Yap and Toh, 2019). However, many organisations do not have available capital to experiment with innovation. There is a failure to learn and evolve successful innovations that limit adaptability and the attitude towards innovation (Mark et al., 2021). AI brings a new tool and process that changes people, processes, communication, and unavoidable work culture (Enegbuma et al., 2015). The findings also support those of Chatterjee et al. (2020), Olawumi and Chan (2020) and Pan and Pan (2020). It implies that effective leadership in organisations should take holistic to shape the attitude of employees toward intending to adopt the new system. Organisational readiness reflects the need for financial and human resources in construction AI adoption. Organisational readiness also gives the organisation understanding of the AI maturity measurements of performance, reliability, durability, and operational experience in the expected environment (Salazar and Russi-Vigoya, 2021). Stakeholders in the construction industry play a critical role in adopting innovation by defining rules and standards and giving direction and assistance, decreasing the risk of AI technology adoption significantly (Yuan et al., 2021).
Component 2 - Competence-Based Development
This component has five sub-components, mainly competitive pressure (0.726), information processing management (0.709), firm size (0.627), knowledge and competency (0.510) and government pressure (0.543). This cluster accounts for 7.760% of the variance, as shown in Table 4. This component was significant at a p-value of 0.001 at a path coefficient of 0.304.
The findings support those of Olawumi and Chan (2020). Human knowledge capacities facilitate information required, which can take up AI in organisations. Competence-based development is more than just putting learning into action. The manager must integrate several areas of knowledge and abilities in a relevant and opportunistic manner for each circumstance and setting they must deal with. As a result, the only way to succeed is to exercise decision-making about external pressure, business size, and the ability to comprehend information. As a result, stakeholders can develop their competencies by addressing various problematic situations (Lantelme et al., 2017). Competitive pressure operates as a prompt for organisations to adopt AI-based innovations to remain competitive. Moreover, competitive pressure drives organisations in all industries to seek competitive advantages by adopting new technologies (Pan and Pan, 2020). Organisations in the construction industry have realised that their competitiveness is dependent on the speed with which innovation and knowledge transfer. The value of innovation as a source of long-term competitive advantage for project-based businesses is becoming increasingly apparent. Businesses constantly use AI to produce new knowledge and abilities (Sergeeva and Duryan, 2021). This outcome shows that building a digital strategy is a strong requirement for organisations operating in competitive environments (Trocin et al., 2021). According to Ghobakhloo and Ching (2019), developing information management capabilities is associated with higher AI innovation diffusion in the construction industry. AI provides a construction organisation’s optimisation strategy and opportunities to apply relevant information management approaches and a collaboration platform to help the team get involved in the process much earlier. This information includes several resource flows that need to be aligned, including the workforce, building information, plant and equipment hire, and the procurement and delivery of materials and components (Alwan et al., 2017). Mabad et al. (2021) noted small size construction organisations based in remote areas are likely to struggle in search of the expertise necessary to execute any necessary support in AI adoption. Lack of a comprehensive. The lack of government support in AI strategy for construction in infrastructure restricts the use of AI. So much so that the benefits are often not recognised or understood by decision-makers, and as a result, the focus is on more day-to-day activities (Bolpagni and Bartoletti, 2021).
Component 3 - Collaborative Decision Making
This component has three sub-components, mainly top management skills (0.763), decision making support (0.762) and collaboration (0.710). This cluster accounts for 6.852% of the variance, as shown in Table 4. This component was found not to be significant at a p-value of 0.004 at a path coefficient of 0.161.
The findings support McAleenan (2020) and Olawumi and Chan (2020). Collaborative decision making is an integrated process that employs digital technology like AI in a virtual and shared environment, anchored by people, processes, and procedures, to enable collective stakeholders to assess, plan, and execute a project at any stage of its life cycle. Efficient, effective, and transparent information transfer is crucial to eliminate errors and cost overruns, increase the quality of exchanges between multiple stakeholders, and take advantage of toolsets, innovations, and better governance processes (Pidgeon and Dawood, 2021). This finding suggests that the best opinion comes from combining people’s input with technology in making organisations sustainable. It was emphasised that top management of construction firms train their staff and increase their knowledge and awareness of AI. Top management is important to the construction industry’s continued and effective implementation of these novel technologies. Additionally, the firm’s leadership support can take several forms, including decision-making assistance, restructuring the firm’s structure and policies to accommodate the new concept and training assistance. When making the right adoption decisions, top management should consider the potential benefits and drawbacks of the available construction robots. AI assists in making decisions in response to barriers, disagreements, and abnormalities discovered throughout the scheduled production. AI is equipped with methods for capturing and reusing knowledge to improve decision-making, weighted according to the project’s features and needs and the external environment (Yap and Toh, 2019). Moreover, AI functions through a single source of information for a project and plays a supporting role in decision-making during its life cycle (Moshood et al., 2020). The ability of an organisation’s employees to collaborate in developing AI-based systems boosts the possibility of the organisation adopting AI technologies (Mabad et al., 2021). The nature of construction organisations is project-oriented, necessitating collaboration and interaction among diverse stakeholders and specialists throughout the project life cycle, posing significant challenges for agreement on innovation adoption among various groups (Pan and Pan, 2020).
Component 4 - Strategic Analysis
This component had three sub-components improved performance (0.67), risks involved in using AI technologies (0.629) and time-saving (0.623). This cluster accounts for 6.070% of the variance, as shown in Table 4. This component was found not to be significant at a p-value of 0.002 at a path coefficient of 0.291.
The findings support that of Turner et al. (2020) and Mabad et al. (2021). Strategic analysis is a key component in establishing a company’s effective strategy. It provides a realistic appraisal of a company’s resources, time, and capabilities regarding the situation of the external environment. The rational choice of strategies from a possible set of options should occur due to this analysis (Makovetskaya and Yuzikhanova, 2018). These findings suggest that organisations weigh the advantages and disadvantages of adopting AI. It may be advantageous in the long run. However, there will be challenges and sacrifice required as adoption is still in its infancy in South Africa. According to Mabad et al. (2021), the value of AI technology lies in its performance. AI tools improve prediction, modelling performance, and accuracy in construction organisations and project aspects. Organisations can use AI to establish digital processes and service innovation, which can help them perform better in terms of perceived fairness, less biased decision-making, transparent feedback, and greater communication, among other things (Trocin et al., 2021). Communities of practice can grow into risk-free, loosely coupled operating systems that foster organisational innovation and learning across functional and project boundaries while increasing creativity and problem-solving effectiveness (Sergeeva and Duryan, 2021).
Implications
Implications for Research
While studies on AI in the construction industry do not look at the adoption of AI and related technologies. These studies also do not look at the relationships of the construct organisational factors. Therefore, the research contributes to AI adoption literature by providing a clearer understanding of related organisational factors of AI adoption in the South African construction industry and their relationship. Subsequently, identifying adoption factors enabled an important knowledge foundation with suggestions for successfully adopting AI techniques in the construction industry. This study also presents empirical data to guide researchers on drafting roadmaps for the South African construction industry and other developing countries. This should be through a clear research design of how the adoption of AI in the construction industry organisations will provide effective and efficient running.
Implications for Practice
Adopting AI in business operations and functions could enhance effective organisational management. AI adoption can ensure improvement in business products and services and save organisations huge costs on investment. To remain competitive, organisations need to constantly measure productivity and attend to the factors identified in this study. This will provide an edge to leverage AI adoption in setting and monitoring targets, business processes, construction, accountability, and other engagements. Knowledge management strategies will also be enhanced as storing, sharing and gaining of knowledge can be facilitated through AI adoption.
In addition, organisations’ management and leadership can emphasise greater pressure to increase awareness and perception of the strategic value of adopting AI technologies in their organisations. This is because it will bring profits for improving productivity, efficiency, quality and collaboration. The adoption can help to ensure effectiveness, safety, and sustainability, thus improving the poor image of the construction industry in the long run.
Further, many unsolved issues are to be addressed, such as the lack of standards for many technologies, the increased demand for AI, and the growing need for improved stakeholder engagement and partnership collaboration. Other considerations include regulatory compliance, legal, and contractual uncertainties. Given this, it is evident that construction organisations must be encouraged to adopt through government regulations and industry bodies. This can also be done through demonstration pilot projects and workshops. The approach could be based on the factors presented in this study.
In addition, the government and industry bodies should promote the use of AI through human capital development of training programs. This promotion can help change worker attitudes and behavioural intentions, thus enabling a favourable disposition to use AI in the construction industry.
Conclusion
The adoption of AI in the construction industry is still uncertain, especially in developing countries’ organisations. The benefits among these nations are yet to be seen. This study contributes to academic research on AI adoption in developing countries. It points out the fundamental factors confronting the construction industry in South Africa to have it in their organisations. While many previous studies have provided in-depth evidence of AI adoption factors in developing countries’ construction and allied industries, none has used EFA and CFA to measure the constructs. In filling this research gap, this study, through literature review and empirical investigation, has identified characteristics of AI in the construction industry organisations in developing countries. The Systematic literature found 17 factors contributing to AI adoption. The study conducted a factor analysis in organisational factors among South African construction professionals. A total of 169 online questionnaires were completed.
However, previous studies have identified organisational factors of AI in the construction and allied industries. This study presented the organisational factors of AI in the construction industry using EFA and CFA, a method not used in articles presented in the SLR identified. The use of CFA improves the measurement of the constructs. It thus enhances understanding of the underlying components of a construct and its relationship with AI in the construction industry. EFA yielded a four-component cluster: innovative organisational culture, competent-based development, collaborative decision-making, and strategic analysis. The CFA tested for convergent validity and measured the measurement model’s adequacy. Innovative organisational culture and competence-based development were significant at a p-value of 0.001.
Future research should address the research limitation of geographic and systematic literature review. Future research should also adopt a Delphi technique to collect expert based judgement to get consensus on the identified organisational factors of AI in the construction industry.
Limitations
Although the objective of this study was achieved, there are limitations to conclusions derived from the results. The study only covered the opinions of construction professionals in South Africa. Therefore the results can only be interpreted in the South African context. Furthermore, the study limited the literature review to certain databases, years and publication types.
Recommendations
Based on the study findings, the following are recommended.
Industry Recommendation
• Organisations should change traditional work culture in order to foster AI adoption. This is because of the value capabilities it brings in achieving efficiency, sustainability and productivity within the construction organisations and projects
• Organisations should look at introducing learning tools and skills to develop employees on AI knowledge
• Top management should include employees when working on AI adoption strategies
