Project schedule management is an important part of prefabricated construction project management. General contracting is an effective way to promote the development of prefabricated construction. However, at present, from the perspective of general contracting, the risk factors affecting the project progress of prefabricated buildings are not clear, and the relationship between risks is not known. The purpose of this study is to study the composition, hierarchical structure and transmission path of schedule risk factors of prefabricated construction in general contracting mode, so as to help the general contractor formulate effective schedule risk avoidance measures. This study uses grounded theory to obtain 22 risk factors that affect the progress of assembly building projects, and the data are from expert interviews. Using Delphi method and interpretative structural modeling (ISM), these factors are divided into seven levels, and the ISM model of schedule risk factors is constructed. The research shows that there are 60 progress risk transmission paths, and four progress risk transfer chains are obtained. This paper also further analyzes and puts forward suggestions to avoid risks for each level. Doi: 10.28991/CEJ-2022-08-01-010 Full Text: PDF

Schedule Management

The reliability of schedule management directly affects the project cost and quality. Time limit is the most important part in schedule management. The determination of reasonable time limit can save cost for investors, and ensure project quality .Based on this characteristic, this paper adopts utility curve to carry out risk analysis for risk factors, eliminates unreliable construction period and carries on fuzzy comprehensive evaluation for the rest of the possible period. Then it got scientific and reasonable time limit. The method can determine the construction period credibly and is used to guide engineering practical.

Construction Schedule

Construction project schedule delay is a worldwide concern and especially severe in the Ethiopian construction industry. This study developed a Construction Schedule Risk Assessment Model (CSRAM) and a management strategy for foreign general contractors (FGCs). 94 construction projects with schedule delay were collected and a questionnaire survey of 75 domain experts was conducted to systematically select 22 risk factors. In CSRAM, the artificial neural network (ANN) inference model was developed to predict the project schedule delay. Integrating it with the Garson algorithm (GA), the relative weights of risk factors with rankings were calculated and identified. For comparison, the Relative Importance Index (RII) method was also applied to rank the risk factors. Management strategies were developed to improve the three highest-ranked factors identified using the GA (change order, corruption/bribery, and delay in payment), and the RII (poor resource management, corruption/bribery, and delay in material delivery). Moreover, the improvement results were used as inputs for the trained ANN to conduct a sensitivity analysis. The findings of this study indicate that improvements in the factors that considerably affect the construction schedule can significantly reduce construction schedule delays. This study acts as an important reference for FGCs who plan to enter or work in the Ethiopian construction industry.

Construction projects are subjected to a variety of risks eventually affecting the overall duration and green building projects are no exception. Use of risk assessment means in such projects is also critical to complete them within aimed schedule. In this study, risks that have potential schedule impacts in certified green building projects are identified and their impact and likelihood of occurrence values are researched. For this purpose, a survey is administered to construction professionals with green building experience. Based on the responses, risks are plotted to draw their potential impact on schedule/likelihood of occurrence in a graph to identify the most significant risk factors. This tool may help the practitioners to identify and prioritize potential risks and allocate resources in projects accordingly to prevent or minimize their possible impacts.

The purpose of Engineering Procurement Construction (EPC) general contracting project schedule management is to ensure that the project meets its deadlines, and it plays a critical role in contract performance. In comparison to the domestic general contracting model, project management and coordination are more complex for the general contractor of international EPC projects. As a result, scientific project schedule process control is critical to effectively ensuring project duration, saving project costs, improving project management level, and project quality, and ensuring that the project achieves the promised advantages for both the contractor and the owner. Through the research and analysis of the status of the schedule management of the Indonesia B Project Phase II cement project, corresponding optimization measures are proposed for the project schedule process control.

Cardiovascular diseases (CVD) may be mediated through increases in the cardiovascular risk factors. Hemoglobin A1c (HbA1c) also called glycated hemoglobin is presently used for the diagnosis and management of diabetes. It has adverse effects on cardiovascular system. This review deals with its synthesis and effects on the cardiovascular system. The serum levels of HbA1c have been reported to be affected by various factors including, the lifespan of erythrocytes, factors affecting erythropoiesis, agents interfering glycation of Hb, destruction of erythrocytes, drugs that shift the formation of Hb, statins, and drugs interfering the HbA1c assay. Levels of HbA1c are positively correlated with serum glucose and advanced glycation end products ( AGE), but no correlation between AGE and serum glucose. AGE cannot replace HbA1c for the diagnosis and management of diabetes because there is no correlation of AGE with serum glucose, and because the half-life of protein with which glucose combines is only 14-20 days as compared to erythrocytes which have a half-life of 90-120 days. HbA1c is positively associated with CVD such as the carotid and coronary artery atherosclerosis, ischemic heart disease, ischemic stroke and hypertension.HbA1c induces dyslipidemia, hyperhomocysteinemia, and hypertension, and increases C-reactive protein, oxidative stress and blood viscosity that would contribute to the development of cardiovascular diseases. In conclusion, HbA1c serves as a useful marker for the diagnosis and management of diabetes. AGE cannot replace HbA1c in the diagnosis and management of diabetes. There is an association of HbA1c with CVD which be mediated through modulation of CVD risk factors.
