Prefabricated Building

Prefabricated construction has been widely accepted as an alternative to conventional cast-in-situ construction, given its improved performance. Great efforts have also been made to develop prefabricated construction technologies in China. However, there is a lack of an appropriate pattern for evaluating its comprehensive economic merits, and reasonable mathematical models for providing a comparative analysis of conventional cast-in-situ and prefabricated building projects have yet to be developed. Therefore, the research in this paper aims to comprehensively evaluate the economic benefits of implementing prefabricated construction techniques in order to surpass the economic barrier and promote the development of prefabricated buildings in China. The comprehensive economic evaluation is formulated in terms of resource-use efficiencies, project progress, and incentive policies. An apartment building in Shanghai is selected as a case study. Construction progress is simulated on the BIM platform when the same case study is rationally transformed from the prefabricated to the conventional cast-in-situ construction technique. The results reveal that the comprehensive economic merit can reach ¥739.6/m2 when selecting the prefabricated construction process. The economic benefit brought by shortening the construction period can be regarded as the most significant contributor. Yet, the current incentive policies only contribute 7.1% of the comprehensive economic evaluation. Overall, this research contributes an assessment framework for decision-making in the technique management of building construction. The BIM-based simulation approach can greatly help investors to identify the relevant economic factors and adopt the latest incentive policies.

Prefabricated Building

Rapid progress has been made in the intelligent technology of prefabricated buildings in recent years, and the related scheduling in many fields such as component production, workshop assembly, and road transportation is used for the optimization of resources. In this paper, the prefabricated building project is taken as the research objective to analyze the constraint conditions between prefabricated building projects in detail. It is proposed that the radial basis function (RBF) fuzzy logic neural network algorithm should be introduced into the optimization of building resource scheduling. Finally, the results of the experimental analysis suggest that the proposed method can effectively address the problem of resource scheduling in the prefabricated construction project, which can also provide a reference for the managers of prefabricated construction projects.

Significant Attention

The study of ethnicity and the interaction between cultures has been a popular topic with ancient historians recently, and this trend continues. While the interconnection between Greek identity and culture and Roman power during the Second Sophistic has attracted significant attention in the last few decades, the earlier periods have remained relatively unexamined. This is now nicely redressed by an important collection of essays edited by Thomas Schmitz and Nicolas Wiater, which focuses on the first century bce. One main theme of the volume concerns the interaction between Greek and Roman identities, and the ways in which authors reinterpret and destabilize them: the interaction between Rome and Greek classicism (Dihle), the rethinking of Greek and Roman cultures and identities in Dionysius (Wiater), the impact of Rome on its resident Greek authors (Hibder), the interpretatio graeca of Augustus by Nicolaus of Damascus (Pausch), the Roman context of Mytilenean intellectuals and their self-fashioning (Bowie), and Greek poets and their Roman patrons (Whitmarsh). A second main theme concerns the interaction with the Greek past and its classics, and the extent to which the classicist approaches of the Second Sophistic are already present in the first century. This is variously explored, from Dionysius’ exploration of stylistic models (Fox), Diodorus’ image of Athens (Schmitz), the tendency to systematization in various intellectual fields on the basis of the classics (Most), the grammarians’ attitude to Greek dialect (Hintzen), and the Homeric quotations in Chariton (Baumbach), to the (re)building projects in Athens (Borg).

Prefabricated Building

Prefabricated construction is an effective and efficient approach to improve construction processes, productivity, quality, and cost-effectiveness. There are, however, practical problems in this approach, including higher risk levels, and cost and time overruns. This study aims to develop a systematic approach for determining the key factors that affect investment risk of prefabricated building projects and assess this risk. Based on literature review, a structured questionnaire was distributed to 210 China-based construction organizations. Relevant evaluation index weights were obtained via questionnaire, and the application of structural equation modelling led to quantitative evaluation of investment risk in the prefabricated construction industry. The results show that the following systems have the most influence on investment risk (from high to low): economy, technology, market, management, and policy, and that the investment risk of such projects can be assessed using structural equation modelling. Relevant measures are presented to guide investment risk evaluation of projects. This study contributes to literature by considering investment risk influencing factors in this field. Further, the findings can help in understanding the implementation and investment risk control of prefabricated building projects, while providing valuable information to departments that make decisions on improving investment risk performance of such projects.

Prefabricated Building

In recent decades, Iraq has witnessed several military operations. This has led to huge damages to the infrastructure of some main cities. The traditional construction methods seem not to be able to fulfill the rapid reconstruction works needed, while prefabricated building systems seem to be promising. This paper aims at evaluating the possibilities of using prefabrication systems for schools building as a pilot study for wider adoption. An extensive literature review was carried out to identify the features of construction prefabrication and its requirements. Then a thorough investigation of the possibilities of adopting this approach in Iraq and the major expected obstacles was carried out. A questionnaire survey has been conducted with (96) stakeholders who have experience in prefabricated building projects. The results showed that the highest rating of benefits went to time and productivity, while the highest rating of obstacles went to lack of government support. Therefore the top proposed action included the adoption of a clear governmental strategy for change. Finally, the respondents agreed that school building is the most suitable type of projects to start with.
