Abstract

Purpose

Completing construction projects within the planned schedule has widely been considered as one of the major project success factors. This study investigates the use of technologies to address delays in construction projects and aims to address three research questions (1) to identify the adopted technologies and proposed solutions in the literature, (2) to explore the reasons why the delays cannot be prevented despite disruptive technologies and (3) to determine the major strategies to prevent delays in construction projects.

Design/methodology/approach

In total, 208 research articles that used innovative technologies, methods, or tools to avoid delays in construction projects were investigated by conducting a comprehensive literature review. An elaborative content analysis was performed to cover the implemented technologies and their transformation, highlighted research fields in relation to selected technologies, focused delay causes and corresponding delay mitigation strategies and emphasized project types with specific delay causes. According to the analysis results, a typological framework with appropriate technological means was proposed.

Findings

The findings revealed that several tools such as planning, imaging, geo-spatial data collection, machine learning and optimization have widely been adopted to address specific delay causes. It was also observed that strategies to address various delay causes throughout the life cycle of construction projects have been overlooked in the literature. The findings of the present research underpin the trends and technological advances to address significant delay causes.

Originality/value

Despite the technological advancements in the digitalization era of Industry 4.0, many construction projects still suffer from poor schedule performance. However, the reason of this is questionable and has not been investigated thoroughly.

Abstract

Purpose

Delay and disruption claims involve a complex process that often result in disputes, unnecessary expenses and time loss on construction projects. This study aims to review and synthesize the contributions of previous research undertaken in this area and propose future directions for improving the process of delay and disruption claims.

Design/methodology/approach

This study adopted a holistic systematic review of literature following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A total of 230 articles were shortlisted related to delay and disruption claims in construction using Scopus and Web of Science databases.

Findings

Six research themes were identified and critically reviewed including delay analysis, disruption analysis, claim management, contract administration, dispute resolution and delay and disruption information and records. The systematic review showed that there is a dearth of research on managing the wide-ranging information required for delay and disruption claims, ensuring the transparency and uniformity in delay and disruption claims’ information and adopting an end-user’s centred research approach for resolving the problems in the process of delay and disruption claims.

Practical implications

Complexities in delay and disruption claims are real-world problems faced by industry practitioners. The findings will help the research community and industry practitioners to prioritize their energies toward information management of delay and disruption claims.

Originality/value

This study contributes to the body of knowledge in delay and disruption claims by identifying the need for conducting more research on its information requirements and management. Subsequently, it provides an insight on the use of modern technologies such as drones, building information modeling, radio frequency identifiers, blockchain, Bigdata and machine learning, as tools for more structured and efficient attainment of required information in a transparent and consistent manner. It also recommends greater use of design science research approach for delay and disruption claims. This will help to ensure delay and disruption claims are the least complex and less dispute-prone process.

Abstract

The present paper presents the major causes of delays in the construction industry in Lebanon and the relative importance of these postponements. A survey of a randomly selected sample of 11 owners, 15 contractors and 10 architectural/engineering (A/E) firms from Lebanon was undertaken. The survey included 64 causes of delay, grouped into 10 major groups, in which the participants were asked to indicate their level of importance of each delay. The level of importance of the causes and the groups were measured and ranked by the importance index for owners, contractors and A/E firms. It was found that all three parties generally agreed on the ranking of the major categories of delay factors. Owners had more concerns with regard to financial issues, while contractors ranked contractual relationships highest, and finally, A/E firms ranked project management highest.

Abstract

Purpose

The purpose of this paper is with delay-independent stabilization of nonlinear systems with multiple time-delays and its application in chaos synchronization of Rössler system.

Design/methodology/approach

Based on linear matrix inequality and algebra Riccati matrix equation, the stabilization result is derived to guarantee asymptotically stable and applicated in chaos synchronization of Rössler chaotic system with multiple time-delays.

Findings

A controller is designed and added to the nonlinear system with multiple time-delays. The stability of the nonlinear system at its zero equilibrium point is guaranteed by applying the appropriate controller signal based on linear matrix inequality and algebra Riccati matrix equation scheme. Another effective controller is also designed for the global asymptotic synchronization on the Rössler system based on the structure of delay-independent stabilization of nonlinear systems with multiple time-delays. Numerical simulations are demonstrated to verify the effectiveness of the proposed controller scheme.

Originality/value

The introduced approach is interesting for delay-independent stabilization of nonlinear systems with multiple time-delays and its application in chaos synchronization of Rössler system.

The purpose of this paper is to determine the factors associated with patient delay among tuberculosis patients in border hospitals, Chiang Rai province, Thailand.

Abstract

Purpose

The purpose of this paper is to determine the factors associated with patient delay among tuberculosis patients in border hospitals, Chiang Rai province, Thailand.

Design/methodology/approach

A cross-sectional study was conducted in the four biggest border hospitals in Chiang Rai province, Thailand during May to July 2018 among 103 identified TB cases. Data were collected by a face-to-face interview with structured questionnaire on patients’ general characteristics, HIV status and patient delay status. Descriptive statistics were used to analyze the patients’ general characteristics, HIV and patient delay status. The association among variables and patient delay was analyzed by χ2-test. The variables with p-value<0.20 obtained in bivariate analysis were further analyzed by binary logistic regression and considered significant with p-value<0.05.

Findings

All patients enrolled, most were reported with patient delay (65.0 percent). Bivariate analysis demonstrated that level of education, nationality and HIV status were associated factors for patient delay. Among these factors, binary logistic regression revealed that HIV negative TB patients were increased 6.806-fold odds of being patient delay (OR = 6.806; 95% CI: 1.174–39.462), while non-Thai TB patients were also increased 2.824-fold odds of being patient delay (OR = 2.824; 95% CI: 1.041–7.660).

Originality/value

Patient delay among TB patients in Chiang Rai province was high. This study further supports the requirement on promoting of TB knowledge and awareness emphasized on non-Thai population and general public along the border areas of Chiang Rai province.

Abstract

Purpose

This study aims to develop a comprehensive conceptual framework that serves as a foundation for identifying most critical delay risk drivers for Building Information Modelling (BIM)-based construction projects.

Design/methodology/approach

A systematic review was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to identify key delay risk drivers in BIM-based construction projects that have significant impact on the performance of delay risk predictive modelling techniques.

Findings

The results show that contractor related driver and external related driver are the most important delay driver categories to be considered when developing delay risk predictive models for BIM-based construction projects.

Originality/value

This study contributes to the body of knowledge by filling the gap in lack of a conceptual framework for selecting key delay risk drivers for BIM-based construction projects, which has hampered scientific progress toward development of extremely effective delay risk predictive models for BIM-based construction projects. Furthermore, this study's analyses further confirmed a positive effect of BIM on construction project delay.

Abstract

Purpose

Patients undergoing emergency appendicectomy incur various delays from the time of symptom onset to the time of discharge from hospital. The centralisation of hospital services over recent years has resulted in some patients who attend hospital as an emergency requiring transfer to a different site. An additional delay by way of transfer is thus incurred. The aim of this study was to test for association between various characterised delays with disease and patient outcomes.

Design/methodology/approach

Hospital Episode Statistics (HES) data were used to identify all patients admitted over a one‐year period undergoing appendicectomy. Demographic and time data were extracted from hospital databases and case notes.

Findings

A total of 247 patients were identified from HES data; 25 per cent of patients presented to hospital E necessitating transfer to hospital H. There was no evidence of an association between patient delays, surgeon delays or theatre delays with advanced pathology and complicated appendicitis was not associated with a longer post‐operative hospital stay. The delay to be seen by the surgeons was significantly longer if transferred from one hospital to another, but this did not contribute to a significant difference between the overall delay from admission to operation, overall length of stay or advanced pathology.

Originality/value

The individual delays along the clinical pathway in a patient presenting to hospital with acute appendicitis have been characterised. Patients with acute appendicitis can be safely assessed at one hospital‐site and transferred to another with emergency surgery provision without affecting the delay to operation.

Abstract

The paper describes four methods of dealing with delay claims that effectively sum up the main approaches to this problem that have been offered in the literature. This is then followed by a description and discussion of results from a new survey aimed at finding out exactly how professionals in the UK construction industry approach these difficult issues. It appears that those who deal with delay claims in the UK are likely to use a critical path method network to do this and generally approve of a methodology that attempts to understand how well the contractor would have fared ‘but for’ the existence of employer‐responsible delays. There is less agreement about who should be said to own the float, but as is explained in the paper, it is possible for this matter to be dealt with by the insertion of a clause in the contract documents.

Design/methodology/approach

The differential inequality theory and some novel mathematical analysis techniques are applied.

Findings

A set of sufficient conditions which guarantee the existence and global exponential stability of periodic solution of involved model is derived.

Practical implications

It plays an important role in designing the neural networks.

Originality/value

The obtained results of this paper are new and complement some previous studies. The innovation of this paper concludes two aspects: the analysis on the existence and global exponential stability of periodic solution of memristor-based recurrent neural networks with time-varying delays and leakage delays is first proposed; and it is first time to establish the sufficient criterion which ensures the existence and global exponential stability of periodic solution of memristor-based recurrent neural networks with time-varying delays and leakage delays.

This paper aims to use a new design approach based on a Lagrange mean value theorem for the stabilization of multivariable input‐delayed system by linear controller.

Abstract

Purpose

This paper aims to use a new design approach based on a Lagrange mean value theorem for the stabilization of multivariable input‐delayed system by linear controller.

Design/methodology/approach

The delay‐dependent asymptotical stability conditions are derived by using augmented Lyapunov‐Krasovskii functionals and formulated in terms of conventional Lyapunov matrix equations and some simple matrix inequalities. Proposed design approach is extended to robust stabilization of multi‐variable input‐delayed systems with unmatched parameter uncertainties. The maximum upper bound of delay size is computed by using a simple optimization algorithm.

Findings

A liquid monopropellant rocket motor with a pressure feeding system is considered as a numerical design example. Design example shows the effectiveness of the proposed design approach.

Research limitations/implications

The proposed approach can be used in the analysis and design of the uncertain multivariable time‐delay systems.

Originality/value

The paper has a great potential in the stability analysis of time‐delay systems and design of time‐delay controllers and may openup a new direction in this area.
