This paper aims to provide decision support for precast concrete contractors about both precast concrete supply chain strategies and construction configurations.

Abstract

Purpose

This paper aims to provide decision support for precast concrete contractors about both precast concrete supply chain strategies and construction configurations.

Design/Methodology/Approach

This paper proposes a simulation-based optimisation for supply chain and construction (SOSC) during the planning phase of PC building projects. The discrete event simulation is used to capture the characteristics of supply chain and construction processes, and calculate construction objectives under different plans. Particle swarm optimisation is combined with simulation to find optimal supply chain strategies and construction configurations.

Findings

The efficiency of SOSC is compared with the parametric simulation approach. Over 70 per cent of time and effort used to simulate and compare alternative plans is saved owing to SOSC.

Research Limitations/Implications

Building simulation model costs a lot of time and effort. The data requirement of the proposed method is high.

Practical Implications

The proposed SOSC approach can provide decision support for PC contractors by optimising supply chain strategies and construction configurations.

Originality/Value

This paper has two contributions: one is in providing a decision support tool SOSC to optimise both supply chain strategies and construction configurations, while the other is in building a prototype of SOSC and testing it in a case study.

Abstract

Purpose

The purpose of the study is to explore the dominant ideas in research on the management of time in construction. The focus of research has been to improve techniques for optimising the timing and sequence of activities.

Design/Methodology/Approach

A critical review of research on construction time management, challenging the typical focus. We examine the assumptions different authors make, underline the limitations of the dominant research approaches and examine the prospects for developing a new approach to researching these issues.

Findings

The dominant approach in literature focuses on unique activity traits in construction planning and measurable patterns between time-related variables. This assumes that time in construction can be managed by changing the way activities are calculated. These approaches have not been correlated with improvement in performance. Social practice theory may help to explain how programmes figure as one of many objects used during construction.

Research Limitations/Implications

The focus is on reviewing indicative literature from key journals in construction management. The implication is that research is needed about how such documents are used in practice, which goes further than optimising plans in theory.

Practical Implications

Future research could focus on understanding the context of construction planning practice and shift the debate from a focus on optimisation to practice.

Originality/Value

An interpretivist approach with a focus on how tools such as planning documents are used on site. Social practice theory may provide a clearer explanation of the place of construction planning within the practice of construction management. This could provide solutions that deal effectively with stakeholder expectations around timely completion of construction projects.

Abstract

Purpose

Low productivity in construction is typically blamed on the seemingly complex and chaotic nature of construction, which emerges as the stakeholders do not have an adequate picture of the evolving situation. The ever-increasing volume of situation data owing to the recent advances in IoT devices and reality capture platforms provide a unique opportunity to capture the actual situation data of construction projects accurately at a fraction of the cost compared to manual status tracking and reporting. This paper aims to investigate the concept of a situation picture, challenges in collecting situation data and its benefits.

Design/Methodology/Approach

Empirical data is collected through interviews in California and Finland, and by organizing workshops.

Findings

We contribute to literature on managing operational information by defining the concept of a situation picture in the context of construction, specifically from the blue-collar’s perspective during on-site activities. We present the key components of a conceptual information model that represents a situation picture in construction.

Research limitations/implications

The applicability of conceptual information model of situation picture is not tested in practice, but the model will provide a starting point for research to comprehensively integrate social and digital information exchange for improving workflow.

Practical implications

The paper claims that designing and building comprehensive information management infrastructure would contribute to solving the problems of low productivity, quality and safety in construction projects.

Originality/value

Research on situation picture and situation awareness is scarce in the context of construction. The study links various information management technologies and practices to actual construction productivity.

This paper aims to investigate construction site workers’ compliance with various coronavirus (Covid-19) protocols while working on construction sites.

Abstract

Purpose

This paper aims to investigate construction site workers’ compliance with various coronavirus (Covid-19) protocols while working on construction sites.

Design/methodology/approach

This survey was conducted at the end of the imposed lockdown following Nigeria’s upsurge of the Covid-19 pandemic. The survey research method was adopted for the study using a structured questionnaire administered to 246 construction site workers under strict Covid-19 preventive measures. The data was complemented through personal observations of the study site activities. The results were analysed using frequency tables and a factor analytical approach.

Findings

The preventive measures in place on construction sites can be classified into personal protective measures, good etiquette/manners, contact precautions and prompt actions. Although the workers claimed to be aware of the Covid-19 pandemic, their disposition towards the preventive measures on construction sites is worrisome. Hence, their level of compliance with the protocols could mitigate the spread of the virus.

Originality/value

This paper fulfils an identified gap to study the need to promote public health by mitigating the global pandemic’s spread in areas where social distancing cannot be easily observed.

Abstract

Purpose

In the Ghanaian construction industry (GCI), the option for stakeholders to adopt formwork design as a building construction requirement is uncommon place. This is due to the low level of awareness and practice of formwork design. As a result of this, there have been formwork accidents, cost and time overruns in construction. This paper aims to solicit the view of stakeholders on the awareness of formwork design practices in the GCI.

Design/methodology/approach

This paper adopted the interpretivism research philosophy and inductive reasoning. Through a semi-structured interview guide, data was collected. The data (interview) recorded was transcribed using the Amberscript web application. This study used thematic analysis in analyzing the data collected using Nvivo 10 software.

Findings

The data collected from the 22 professionals indicated that the respondents were unaware of the concept of formwork design and its practice, neither could they speak to the existence of any specific regulation nor code of practice. However, the respondents established that there was a need to design formwork and stated some benefits of it.

Originality/value

From the literature, little research has been done on formwork design and its context in the GCI is yet to be explored. This research attempts to fill this gap. The findings indicate that to practice formwork design, there must be education and training of human resources for formwork design, there must be a code of practice to guide the design process and legal backing through policies and regulations to mandate the design.

Abstract

Purpose

International construction joint ventures (ICJVs) are an effective strategy for construction companies worldwide for delivering large and complex projects. Despite numerous ICJVs studies, there is a lack of comprehensive empirical examination of what drives ICJVs implementation. This study aims to investigate the key drivers for implementing ICJVs through an international survey.

Design/methodology/approach

Grounded on a comprehensive literature review and structured questionnaire survey, 123 ICJV experts' responses from 24 different countries/jurisdictions were analyzed using inferential and descriptive statistics. Mann–Whitney U test was used to determine any divergence of ranking of the drivers by the experts. Factor analysis (FA) was used to identify the clusters underlying the key drivers. Rank agreement analysis was later used to investigate the consensus between experts from developing and developed countries/jurisdictions on their ranking of the clusters.

Findings

Out of 34 factors, 26 factors greatly drive the implementation of ICJVs. Mann–Whitney U test results prove the absence of significant disparity among the experts in the ranking of the drivers. Six clusters were obtained through factor analysis (FA), namely, market-penetration and innovation-driven drivers, legal and market-driven drivers, fiscal incentives and market expansion drivers, personal branding drivers, sustainable advantage/power drivers and industrial and organizational promotion drivers. Rank agreement analysis exhibited varied levels of concurrence between professionals from developed and developing countries/jurisdictions.

Practical implications

The appreciation of the factors motivating ICJVs is beneficial to the successful implementation of ICJV strategies. A clear understanding of the drivers can help practitioners and policymakers to customize their ICJVs to reap the expected benefits.

Originality/value

The study has generated valuable insights into the factors that are greatly driving the implementation of ICJVs worldwide. While the findings of this study provide a profound contribution to theory and practice, it contributes to sustainable growth in different perspectives.

This study examines the initiatives that would enable contractors in Singapore to improve the level of construction productivity.

Abstract

Purpose

This study examines the initiatives that would enable contractors in Singapore to improve the level of construction productivity.

Design/methodology/approach

A two-pronged research method was employed: questionnaire survey with contractors (109 responses received) and in-depth interviews with 12 subject matter experts. The questionnaire covered questions such as the current and future improvement measures.

Findings

The results show that the top three motives for achieving high productivity (increase profitability, on time delivery and enhance corporate competitiveness) are underpinned by profit maximization. Factor analysis revealed several categories of productivity improvement strategies. Among these, only site operations category is under the control of contractors. Other important categories include government's initiatives and design factors.

Research limitations/implications

While contractors are the producers of built products, their productivity is very much dependent on other factors and other parties. The long-standing exhortation to contractors to improve productivity is necessary but not a sufficient condition to improve it.

Practical implications

Recommendations are provided for the government, designers, contractors and other stakeholders on what can be done to improve productivity.

Originality/value

This research adds to knowledge by showing that contractors' top motives for high productivity relate to self-seeking behavior to maximize profit. Prior to this study, productivity improvement is considered the responsibility of contractors. This study shows that two other stakeholders also hold the key to productivity improvement – government and designers. Government controls the supply of foreign labor, has the capacity to offer incentives and has the muscle to enact regulations to improve productivity. Consultants' upstream designs must be buildable.

Abstract

Purpose

To effectively implement knowledge management, one prerequisite is to understand and implement the knowledge management enablers in the sense of optimal institutional efficiency. This paper aims to analyze and measure the significant enablers in overseeing knowledge management in the construction sector.

Design/methodology/approach

The mixed-method technique was used to achieve the objective of this study and involved the application of detailed questions to project engineers and project managers within leading construction engineering companies, provided by the Institution of Engineering and Technology Ghana. In total, 150 questionnaires were collected and analyzed using the Statistical Package for Social Sciences v. 26.

Findings

The study confirms that the knowledge management enablers such as employees knowledge, motivations, effective decisions and strategic planning are some of the important ways in which construction professionals can achieve different strategic goals in many processes and concluded that the progress of the next generation knowledge management strategy will be based on content sharing, decision-making and by promoting the free flow of ideas.

Originality/value

The study offers perspectives into knowledge management enablers and recommends key performance factors, championed by Ghanaian construction contractors for institutional knowledge capture.

Abstract

Purpose

Modular construction is widely adopted and used in the construction industry to improve construction performance with respect to both efficiency and productivity. The evaluation of design options for modular construction can be iterative, and thus automation is required to develop design alternatives. This research aims to explore the potential of utilizing the generative design approach to automate modular construction for residential building structures in urban areas such as New York City.

Design/methodology/approach

The proposed research methodology is investigated for a systematic approach to parametrize design parameters for modular construction layout design as well as incorporate design rules/parameters into modularizing design layouts in a Building Information Modeling (BIM) environment. Based on current building codes and necessary inputs by the user, the proposed approach enables providing recommendations in a generative design method and optimizes construction processes by performing analytical calculations.

Findings

The generative design has been found to be efficient in generating layout designs for modular construction based on parametric design. The integration of BIM and generative design can allow industry practitioners to fast generate design layout with evaluations from constructability perspectives.

Originality/value

This paper has proposed a new approach of incorporating generative design with BIM technologies to solve module layout generations by considering design and constructability constraints. The method can be further extended for evaluating modular construction design from manufacturability and assembly perspectives.

Abstract

Purpose

This study aims to investigate the impact of primary building information modelling (BIM)-related factors, extracted from the literature on the subject, on construction project performance.

Design/methodology/approach

Based on data collected from 134 BIM users, this study used structural equation modelling to assess the impact of these factors in five main BIM-related factor clusters.

Findings

The results of the analysis confirmed the reliability and validity of the research design and outcomes. The findings indicated that the BIM-related external factors cluster is the most influential cluster affecting construction project performance. BIM-related project factors and BIM-related technological factors also had a significant impact on project performance. These were followed by the BIM-related management factors cluster, while the BIM-related human factors cluster had a low impact on project performance.

Research limitations/implications

This study will contribute to fostering BIM adoption and implementation in the construction industry in developing countries.

Originality/value

This study has filled a crucial knowledge gap by providing information on manageable primary BIM-related factors affecting construction project performance.
