Modeling Adoption Behavior of Prefabricated Building with Multiagent Interaction: System Dynamics Analysis Based on Data of Jiangsu Province

In recent years, the development of prefabricated building (PB) mode in China has gradually attracted the attention of stakeholders. It is of great significance to explore the adoption behavior of PB mode by Chinese construction enterprises. Using the method of combining evolutionary game theory with system dynamics and considering the multiagent interaction of the government, construction enterprises, and consumers, as well as the influence of multiple factors, this paper constructs a model of construction enterprises' adoption behavior of PB mode. The purpose is to clarify the mechanism of Chinese construction enterprises' adoption behavior of PB mode and the evolution law of market share. The research results show the following. Firstly, government subsidy plays an important role in promoting the maturity of PB market, but it plays a relatively small role in the more mature and stable market. Secondly, the higher the initial acceptance probability of the construction enterprise, the greater the peak of the PB market share and the greater the volatility, but it has no differential impact on the balance of the PB market in the later stage. Thirdly, price factors and quality factors, respectively, have an important impact on the increase of the PB market share in the early and late stages of the formation of the PB market, but the delivery waiting time factor has no significant impact on the PB market share.

Evolutionary Process of Promoting Construction Safety Education to Avoid Construction Safety Accidents in China

Construction safety is related to the life and health of construction workers and has always been a hot issue of concern for government and construction units. The government can use “construction safety education” to reduce the probability of safety accidents in the construction process and avoid the loss of life and property of construction workers. To encourage construction units to provide safety education for construction workers before construction starts and promote construction workers to actively participate in safety education. In this paper, a tripartite evolutionary game model of government–construction units–construction workers is established, and the factors affecting each party’s behavior strategy are comprehensively analyzed. Firstly, evolutionary game theory is used to investigate the influence of different behavior strategies among government, construction units, and construction workers on the behavior strategies of the other two parties. Secondly, according to the events in different situations, the influence of critical factors on the evolution process of the model is analyzed. On this basis, combined with the construction experience and construction data of actual construction projects, the established model and preliminary conclusions are verified. Finally, a sensitivity analysis of all parameters is carried out. The results show that: (1) The government’s enhancement of reward and punishment is conducive to promoting the choice of "providing safety education" for construction orders and the choice of “actively participating in safety education” for construction workers, but the excessive reward will lead to the government’s unwillingness of participation; (2) The reasonable reward and punishment mechanism set by the government must meet the condition that the sum of rewards and punishments for all parties is more significant than their speculative gains, to ensure the construction safety under the evolutionary stability; (3) Increasing welfare subsidies for construction workers who choose to participate in safety education actively is an effective way to avoid unwilling participation of construction workers.

New Normal Set-up on Safety and Health Standards in Government Construction Projects: A case of Covid-19

The New Normal Set-up on Safety and Health Standards in Government Construction Projects during this time of the Covid-19 pandemic is a new guideline or protocol on construction sites in preventing the spread of the coronavirus disease within the construction workers in Central Luzon before, during, and after construction activities. This study aims to verify the effectivity of the New Normal Set-up on safety and health protocol in preventing the spread of the virus during a pandemic crisis. This paper will provide an assessment, evaluation, and recommendations on the current mandated rules of government agencies within Central Luzon in terms of safety and health guidelines in the implementation of construction projects during this Covid-19 public health crisis.

Failure factors–a comparative study of private and government construction firms

PurposeThe purpose of the present study is to examine the failure factors for the construction firms in a developing nation. Furthermore, the comparison of failure factors for private and government firms are evaluated.Design/methodology/approachIn the present study, comparison between private and government construction firms is done in the context of a construction firm failure. About 60 construction firms were selected in and around the Nashik region for the investigation, where a simple multi-attribute rating technique (SMART) is used for analysis purpose.FindingsIt is found that for private firms (private contractors and builders) lack of experience is the major factor for failure of the business as against lack of managerial experience is a critical factor in case of a government contractor.Practical implicationsThe outcome of the present study will be used to guide the policymakers during the implementation of governmental and private projects in order to lessen the construction project failures.Originality/valueConstruction company failure is an important aspect in developing countries like India. The limited studies were available in literature which shows failure factors for government and private firms and distinguished them. Hence, the present study extends the construction company failure literature by focusing on government and private firms. Also, the study provides some theoretical guidelines for management to avoid construction company failure in India.

The history of research and development of the Yamal region by student construction units of the USSR (1950—1970)

Rational proposals for the development of the Arctic region came not only from scientists from research institutes, but also from other specialists. A large number of hypotheses and proposals for the development of the Arctic regions of the USSR were considered. At the same time, the emphasis was made on the construction of transport hubs, including cargo-forming and storage facilities with large industrial centers in Yamal. Student construction units came to the aid of the government. Construction teams were an effective way to provide secondary employment for young people, organize leisure life, the opportunity for creative activity through the self-realization of ideas and the inclusion of youth in creative work.

Streamlining the management of payment delays: the case of Sri Lankan Government building construction projects

Purpose Delayed payments have been long standing, pressing issue in construction projects, especially in Government-funded construction projects. The root causes and the consequences of delayed payments must be identified before implementing strategies to mitigate the consequences of such delayed payments. However, these causes and consequences and the parties responsible for managing the delayed payments have not been identified so far. Therefore, the purpose of this study is to investigate the management of payment delays in Government-funded construction projects. Design/methodology/approach The study used a mixed approach comprising four case studies and a questionnaire survey. The empirical data collected from the case studies and the questionnaire survey were analysed using manual content analysis and mean rating, respectively. Findings The study identified the most significant causes and the most significant consequences of delayed payments that occur in Government-funded construction projects. It also revealed the strategies that clients, consultants, contractors and other parties can adopt to mitigate the adverse consequences of such delayed payments. Originality/value This study identified the most significant causes of delayed payments in Government-funded construction projects, the most significant consequences of such delayed payments and the most suitable strategies the clients, consultants and contractors can adopt to mitigate the consequences of such delayed payments. Thus, this study supports streamlining the management of payment delays in Government construction projects and identifies the roles that different parties must play in managing payment delays in Government building projects, which is an under-researched area.

THE URGENCY OF THE PUBLIC POLICY OF THE CONSTRUCTION SERVICE COOPERATIVES IN REALIZING THE WELFARE OF THE COMMUNITY BASED ON JUSTICE VALUE

Cooperatives are the support of the national economic order which is an integral and inseparable part, so that’s why it is not only the mandate of the constitution but also becomes hopes in building the people's economy. This study utilized a sociological juridical approach by examining the rules, concepts, community views, legal doctrines obtained from secondary legal materials, as well as applicable laws and regulations relating to the issues discussed. The results found the factors that influence cooperative public policy that has not been able to play a role in the field of government construction services by basing on legal system theory are caused by 3 legal subsystem factors (first legal factors, second legal structure factors, and legal culture factors). Thus, based on the values of justice, it is necessary to reconstruct the laws and regulations, especially the provisions of Article 6, Article 15 and Article 16 of Law No. 25 of 1992 concerning cooperatives.

Causes of government construction projects’ abandonment

Government construction projects are vital to the economic development of developing countries. However, although most of these projects suffer from abandonment, little evidence exists concerning the causes that account for this setback. This paper investigates the causes of government construction project abandonment in Ghana. We used a sequential data collection approach, in-depth semi-structured interviews, and questionnaire surveys to solicit the views of project management practitioners, contractors, and clients associated with Ghana government construction project implementation. Using factor analysis and structural equation modelling, we find that Ghanaian government construction project abandonment is influenced by five sets of causes: political leadership, culture, external forces, resources (including funding) and administrative/institutional bottlenecks. Three of these sets of causes – political leadership, cultural and external forces, are the primary causes, while resources (including funding) and administrative/institutional causes are secondary causes.
