Analysis Of The Impact Of The Covid-19 Pandemic On The Construction Industry Sector

Accelerating infrastructure development in Indonesia is a good thing, but this is not without problems. The COVID-19 pandemic is a problem that has a large and global impact, not least in Indonesia, especially in the construction industry sector. The construction project of the Soedono Madiun Hospital is one of the construction projects that have experienced the direct impact of the COVID-19 pandemic. Therefore, the purpose of this study is to review and analyze the impact of the covid-19 pandemic on construction projects in the case study of the construction project of the Soedono Madiun Hospital, and to find out the biggest impact of the covid-19 pandemic which has the most influence on construction projects in the case study of the construction project of the Soedono Hospital. Madison. The research method used to determine the biggest impact of the covid-19 pandemic on the cost and time aspects is the multiple linear regression analysis method with the help of Microsoft Excel. The other data analysis methods used in this study were the validity and reliability tests used in testing the questionnaire. The results of data analysis conducted in this study indicate that there are seven independent variables affect the dependent variable, namely the suitability of planning and project realization with the equation y= 94.186-0.376x1-0.108x2-1.014x3+0.873x4 for the time aspect, and the equation y=87,009 -0.0006x5-0.001x6-0.0002x7 for the cost aspect. With this equation, it can be seen that the independent variable that has the most influence on the dependent variable on the time aspect is the independent variable X3, namely the change in the time schedule due to delays in the arrival of construction materials by 1.014, while in the cost aspect is the independent variable X6, namely changes in costs due to instability. the price of construction materials is 0.001. So, it is hoped that there will be a project management handling that focuses on the most influential variable, namely construction materials.

Integration of Data Flows of the Construction Project Life Cycle to Create a Digital Enterprise Based on Building Information Modeling

This study is devoted to the problem of digital transformation in the construction industry. To solve the proposed emerging approach for integrating information flows based on Building information modeling (BIM). This research describes the advanced methodology for creating a unified information model in construction, which combines architectural, design, engineering, cost and depreciation models of a construction object, raises a number of problems of reorganizing business processes at enterprises. The novelty of the research lies in the model of adapted common data environment based on life cycle of a construction project by stages of implementation and emergence of information. The proposed architecture is a platform for intelligent parametric modeling as intelligent CAD, which allows linking all elements of the model "Digital Enterprise".The result of the study is a conceptual mechanism for improving the efficiency of enterprise management processes based on the architectural approach in terms of digitalization of construction. Emerging technology in the study is the architecture of the intelligent decision support system in construction based on 5D BIMtechnology and Digital Enterprise. The main advantage of the proposed approach is the possibility of multiple reuse of information by all participants in the development and implementation of an investment and construction project without changes and distortions of data about the construction object.

7-Score Function for Assessing the Strength of Association Rules Applied for Construction Risk Quantifying

There are several factors influencing the time of construction project execution. The properties of the planned structure, the details of an order, and macroeconomic factors affect the project completion time. Every construction project is unique, but the data collected from previously completed projects help to plan the new one. The association analysis is a suitable tool for uncovering the rules—showing the influence of some factors appearing simultaneously. The input data to the association analysis must be preprocessed—every feature influencing the duration of the project must be divided into ranges. The number of features and the number of ranges (for each feature) create a very complicated combinatorial problem. The authors applied a metaheuristic tabu search algorithm to find the acceptable thresholds in the association analysis, increasing the strength of the rules found. The increase in the strength of the rules can help clients to avoid unfavorable sets of features, which in the past—with high confidence—significantly delayed projects. The new 7-score method can be used in various industries. This article shows its application to reduce the risk of a road construction contract delay. Importantly, the method is not based on expert opinions, but on historical data.

Evaluation of the implementation of occupational safety and health management systems on the ayana nort wing bali construction project

Building construction projects have a high level of risk of work accidents, especially for workers in the field. Therefore, at the time of implementation of construction work, it is necessary to evaluate the implementation of occupational safety and health management system (SMK3) to provide a sense of security to workers in the field of this research aimed at evaluating SMK3. This research uses qualitative and quantitative methods to know the implementation of SMK3, by taking data by conducting structured interviews conducted on the building construction project Ayana Nort Wing Bali. Analysis conducted a descriptive analysis based on Government Regulation of the Republic of Indonesia No.50, 2012 advanced with 12 criteria containing 166 criteria elements. The result of this study is the application of PP No. 50 of 2012 for the advanced level of 92.89% categorized as satisfactory. In addition, there are 14 that have not been implemented. This the company that the evaluation level of occupational safety and health management system (SMK3) in the building construction project Ayana North Wing Bali is the level of application is very satisfactory for the project.
