Purpose Tender price remains an imperative parameter for clients in deciding whether to invest in a construction project, and it serves as a basis for tender price index (TPI) manipulations. This paper aims to examine the factors affecting tender price in the construction industry. Design/methodology/approach Based on the literature review, nine independent constructs and one dependent construct relating to tender pricing were identified. A structured questionnaire survey was conducted among quantity surveyors in Ghana. Partial least squares structural equation modelling (PLS-SEM) examined the influences of various constructs on tender price development (TPD) and the relationships among TPD and TPI. Findings Results showed that cultural attributes, client attributes, contractor attributes; contract procedures and procurement methods; consultant and design team; external factors and market conditions; project attributes; sustainable and technological attributes; and TPI have a positive influence on tender price, whereas fraudulent attributes exert a negative influence. Practical implications The findings offer construction professionals broader understanding of factors that affect tender pricing. The results may be used in professional decision-making in the pricing of construction projects, as they offer clearer causal relations between how each construct will influence pricing. Originality/value This study adds to the body of construction pricing knowledge by establishing the relationships and degree of influences of various factors on tender price. These findings provide a valuable reference for practitioners.

Purpose – In spite of the benefits of virtual models in the building and construction industry, the full potential of these models, especially in the construction and operation phases, remains largely unrealized. With the increasing developments in information and communication technology, a number of attempts have been made to extend the use of these models, through the development of integration approaches and technologies. However, the issue of integrating the virtual model and the physical construction such as to enable bi-directional coordination, has not been adequately addressed. Thus, the purpose of this paper is to investigate the application of a cyber-physical systems (CPS) approach in enhancing bi-directional coordination between virtual models and the physical construction. Design/methodology/approach – This research employs scenario development rapid prototyping to illustrate CPS integration in the construction industry, with a particular focus on facilitating bi-directional coordination. The proof-of-concept prototype systems developed were validated using a focus group consisting of industry practitioners. Findings – Bi-directional coordination between virtual models and the physical construction has the potential to improve real-time progress monitoring and control of the construction process, tracking of changes and model updates, information exchange between the design office and the job site, real-time documentation of the as-built status of high-value components and improved sustainability practices. Originality/value – This paper adds value to the construction industry by demonstrating the application of the CPS approach in enhancing bi-directional coordination between virtual models and the physical construction through the development of system architectures, scenarios and prototype systems.

Virtual Models

Cyber–physical systems (CPS) enable the synergistic integration of virtual models with the physical environment. CPS are being increasingly recognized because of their ability to improve information management in construction projects, make project delivery efficient, and enhance facilities management. The use of virtual models in the construction industry is growing. A quantity surveyor (QS) is responsible for estimating and monitoring construction costs from project inception to completion. The use of CPS could integrate the physical environment with the digital information available to QSs. Hence CPS has the potential to streamline the workflow related to key roles of QSs. Thus, the aim of the study was to evaluate the ability of CPS to facilitate the key roles expected of a QS. The study used a qualitative approach, consisting of 18 semi-structured interviews. The interview findings were analysed using manual content analysis. The literature review revealed the need for CPS in the construction industry and identified the key roles of QSs. The interviewees identified the existing CPS and their supportive applications, technologies and proposed new systems. The study findings provide insights on the reforms required in the key roles of QSs when using CPS.

Wireless sensor networks (WSNs) are key components in the emergent cyber physical systems (CPSs). They may include hundreds of spatially distributed sensors which interact to solve complex tasks going beyond their individual capabilities. Due to the limited capabilities of sensors, sensor actions cannot meet CPS requirements while controlling and coordinating the operations of physical and engineered systems. To overcome these constraints, we explore the ecosystem metaphor for WSNs with the aim of taking advantage of the efficient adaptation behavior and communication mechanisms of living organisms. By mapping these organisms onto sensors and ecosystems onto WSNs, we highlight shortcomings that prevent WSNs from delivering the capabilities of ecosystems at several levels, including structure, topology, goals, communications, and functions. We then propose an agent-based architecture that migrates complex processing tasks outside the physical sensor network while incorporating missing characteristics of autonomy, intelligence, and context awareness to the WSN. Unlike existing works, we use software agents to map WSNs to natural ecosystems and enhance WSN capabilities to take advantage of bioinspired algorithms. We extend our architecture and propose a new intelligent CPS framework where several control levels are embedded in the physical system, thereby allowing agents to support WSNs technologies in enabling CPSs.

Purpose The Nigerian construction industry is bedeviled with poor project performance and outcomes which value management (VM) could address if applied. The application of VM on Nigerian construction projects is very minimal due to certain obstacles, namely, lack of VM experts, paucity of knowledge on the techniques, etc., which inhibits the adoption into the construction industry. Therefore, this study aims to develop a conceptual framework of the adoption of VM on construction projects in a typical developing economy. Design/methodology/approach This study engaged 15 selected VM experts in two rounds of Delphi survey to develop a conceptual framework of VM adoption. The method of data analysis includes mean score, standard deviation, Kendall’s coefficient of concordance, chi-square (χ2) test, interrater agreement analysis and significant level analysis. The developed conceptual framework was sent to a team of local and international VM experts for validation. Findings This study reveals that the adoption of VM requires the collective effort of relevant stakeholders in the construction industry. The framework developed presents individual and collective activities to be undertaken by the stakeholders. The activities include training, legislation, government-funded research, etc. Thus, the adoption of innovative management methodology like VM requires the collaboration of academics, construction professional bodies and government parastatals. This will assist in the judicious use of limited construction resources and boost the relevance of the Nigerian construction industry among developing nations and in the global construction market. Originality/value This study used the opinions of few construction professionals that can be regarded as VM experts in Nigeria, as against engaging a pool of construction professionals who may not be knowledgeable in VM process. Engaging the few VM experts in the Nigerian construction industry is important to have a valid basis for drawing conclusion, as large questionnaire survey could be possibly filled by inexperienced or unqualified respondents if stringent criteria are not considered at the outset of this study.

Purpose Knowledge management (KM) is the central know how for the construction industry. However, the delivery of construction projects is often plagued by schedule delays and cost overruns due to lack of working knowledge of project personnel. Hence, the need to appraise the practices of knowledge management in the construction industry has become all the more germane. This paper aims to determine the awareness of KM practices in Malaysia-based construction small and medium enterprises, and to investigate the benefits, tools and techniques, and challenges associated with knowledge management implementation so that effective measures can be devised to address them. Design/methodology/approach The research data were gathered using a structured questionnaire survey disseminated in the Klang Valley region in Malaysia. Responses were collected from 107 industry practitioners. The quantitative data are subjected to descriptive statistics, and the ranking with category of significance of the hypothesised variables is determined using the relative importance index (RII) technique. Findings The key benefits of KM practices are predominantly raising efficiency, quality, productivity and decision-making. The most preferred KM techniques are “face-to-face interaction”, “mentoring” and “documents and reports”. The highly significant tools are “groupware” and “telephone”. The major organisational issue hampering the implementation of knowledge management practices is “lack of motivation” while the critical cultural issue is relating to “bureaucracy and hierarchical”, and the vital people issue concerns “lack of trust”. Research limitations/implications The respondents were limited to only small and medium construction enterprises located in the Klang Valley region in Malaysia, which makes generalisation challenging. Practical implications KM provides not only a pragmatic but also a proactive approach to raising the competitive edge and capabilities of a construction company. Identification of the critical attributes of KM provides the basis for project managers in formulating KM strategies to enhance the chances of successful delivery of future projects. Originality/value The study contributes to the debate on the knowledge agenda in the construction industry, particularly from a fast developing economy’s perspective, where an effective KM can further contribute to realising a reasonable level of competitiveness operation.

Purpose This paper aims to enlighten the importance of the risk management process which is considered as a major procedure to effectively handle the potential inherent risks in the construction industry. However, most traditional risk analysis techniques are based on theories that deal with each risk factor as an independent, which does not take into consideration the causal relationships between risk factors. Design/methodology/approach This study aspires to identify the overall risk of the administrative construction projects in Egypt and to recognize the most influencing risk factors through the project life cycle by using Bayesian belief networks (BBN). Through a review of the literature, 27 risk factors were identified and categorized as the most common risk factors in the construction industry. A structured questionnaire was performed to estimate the probability and severity of these risks. Through site visits and interviews with experts in the construction field, 200 valid questionnaires were collected. A risk analysis model was developed using BBNs, then the applicability of this model was verified using a case study in Egypt. Findings However, the outcome showed that critical risks that manipulate administrative construction projects in Egypt were corruption and bribery, contractor financial difficulties, force majeure, damage to the structure and defective material installation. Practical implications The proposed study presents the possibilities available to the project parties to obtain a better forecast of the project objectives, including the project duration, total project cost and the target quality by examining the causal relationships between project risks and project objectives. Originality/value This study aspires to identify the overall risk of the administrative construction projects in Egypt and to recognize the most influencing risk factors through the project life cycle by using BBNs.
