Optimalisasi Desain Struktur Gedung Interdisciplinary Engineering (IDE) – Fakultas Teknik Universitas Indonesia dengan Memanfaatkan BIM (Building Information Modelling)

Project design is a step in the construction process that determines the technical requirements to be applied when the project is constructed. BIM (Building Information Modeling) is a form of technological innovation used in project design. BIM (Building Information Modeling) has become the main factor for increasing efficiency and accuracy; using BIM, everything related to design, construction, scheduling, and costs can be integrated into one digital platform that all stakeholders can access. In this paper, the structural planning optimization of the Interdisciplinary Engineering (IDE) Building - Faculty of Engineering, University of Indonesia, will be carried out. This building planning refers to (SNI-2847-2019) concerning Structural Concrete Requirements for Buildings and (SNI-1726-2019) concerning Procedures for Planning for Earthquake Resistance of Structures. Outputs are generated through superstructure and substructure plans, the design of foundation structures, columns, beams, and plates, 2D Detail Engineering Design (DED), 3D modeling, and construction management plans in the form of Budget Plans and scheduling.

The Environmental Influencing Factors of the Realization of Engineering Construction Harmony from the Perspective of Ren–Shi–Wu: Evidence from China

Engineering construction involves many internal factors and external environmental factors, resulting in conflict or uncoordinated problems in engineering management. The harmonious management of engineering construction is the process of coordinating and solving the contradiction between construction elements and the problems between them and the external environment. The connotations of three subsystems of engineering harmony, namely, Ren harmony (RH), Wu harmony (WH), and Shi harmony (SH), are defined, and the system architecture of engineering harmony is constructed. Then, a hypothetical model is proposed to deeply explore the impacts of subsystems such as Ren harmony, Wu harmony, and Shi harmony on engineering harmony, as well as the moderating effects of the natural ecology, social humanities, and political economy on engineering harmony. The results show that (1) natural ecology has a significant promotion effect on RH, SH, and engineering harmony; (2) social humanities have a significant enhancement effect on SH and engineering harmony; and (3) political economy does not play a significant role in any process. “Engineering harmony” is used to measure the effectiveness of engineering management, and a scientific scale is used to reflect this index. It provides a new idea for theoretical exploration and practical guidance in engineering construction management.

Structural monitoring data repair based on a long short-term memory neural network.

As construction technology and project management develop, structural monitoring systems become increasingly important for ensuring large-span spatial structure safety during construction and operation. However, most of the sensors and monitoring equipment in monitoring systems are poorly serviced, resulting in frequent abnormal monitoring data, which directly leads to challenges in data analysis and structural safety assessment. In this paper, a structural response recovery method based on a long short-term memory (LSTM) neural network is proposed by studying the autocorrelation of data and the spatial correlations among data at multiple measurement points. The effectiveness and robustness of the proposed method are verified using the monitored stress data for a grid structure jacking construction process, and the influence of different data loss rates on the recovery accuracy is analysed. The recovery models are compared using a support vector machine and a Multi-Layer Perception (MLP) neural network. The proposed method can effectively restore missing data; notably, the MSE index is 0.6, and the MAPE is below 15%. The data restoration method based on the LSTM neural network is more accurate than the traditional method. Finally, the repair applicability of various types of monitored data is verified using the monitoring data from Hall F of Qingdao Jiao-dong International Airport under typhoon conditions.

The Exploration of the Application and Management of Project Cost in Smart Buildings Using BIM Technology

In recent years, the slow development of engineering construction management in China has been attributed to outdated management models and low level of informatization. To address the deficiencies in project cost management, relevant departments have proposed the application of BIM technology. BIM technology encompasses a wide range of areas, including planning, construction processes, and cost management. It enables the simulation of these processes to create dynamic real-time building models. Additionally, BIM technology facilitates the rapid transmission of various information during the construction process, thereby improving the overall efficiency of the construction project. Information technology has become ubiquitous in people’s daily lives, and this foundation has led to the emergence of smart buildings. The operation and development of smart building projects require effective project cost management. Accurate cost estimation can help construction enterprises effectively control project costs and increase economic benefits. However, many companies still rely on traditional methods such as manual measurement based on drawings, bill of quantities, or engineering rates, which often lead to calculation errors. The application of BIM technology in project cost management can help alleviate this problem.

Application of improved multi objective particle swarm optimization and harmony search in highway engineering

Highway engineering construction is a complex multi-objective management project, and the traditional multi-objective task management approach has been difficult to cope with the uniqueness of highway engineering construction management. In order to improve the efficiency of multi-objective management in highway engineering, the study proposes to construct a multi-objective management model using particle swarm and harmony search algorithms for highway engineering management. First of all, the study first explores the management indexes in highway engineering, and constructs the functional relationship according to the selected indexes. Then the particle swarm algorithm is used to optimize the database of the harmonic search algorithm, and the harmony search algorithm can be based on the optimized database to find the optimal solution for objective management. The experimental results show that the improved particle swarm and harmony search algorithm has good distribution and convergence. After the optimization of the proposed model, the multi-objective highway project management scheme is 39% ahead of schedule, 17% savings in input funds, and 2.56% and 3.56% improvement in highway quality indexes and ecological environment management indexes, respectively, compared with the original scheme. Therefore, the model has a good application prospect to formulate the optimal multi-objective management scheme with excellent performance to improve the management efficiency of highway engineering.

Factors Affecting Road Tunnel Construction Accidents in China Based on Grounded Theory and DEMATEL.

Despite the continuous progress of tunnel construction technology and safety management technology, road tunnel construction safety still faces many challenges in China, such as how to ensure the effective management and safety control of people and materials, how to ensure the implementation of technology and program implementation, risk assessment of construction site environmental information, etc. Exploring the causes of tunnel construction accidents and understanding the properties of the factors and their interrelationships can effectively control the sources of risk and contribute to the safety control of tunnel construction. Therefore, we have collected 30 formal accident investigation reports from the government safety supervision and management department from 2005 to 2021, including detailed investigation and accident analysis. Based on grounded theory, a qualitative research method to generalize experience through direct observation, abstraction, and analysis of data, we use Nvivo11 software to analyze reports and obtain 6 selective codes, 16 spindle codes, and 43 open codes. In addition, we construct a theoretical model of tunnel construction accident influencing factors, which passed the saturation test. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) model is used to analyze the influencing mechanism and interaction relationships of these factors. The two dimensions of influence degree and centrality are used to determine the critical influencing factors of tunnel construction accidents in mountainous areas. They are security awareness and professionalism. According to the cause degree, the influencing factors are divided into cause and result factors. Finally, the basis and suggestions for reducing construction accidents are presented.

Subway as the main means of urban public transport travel, in recent years by people’s favor, although the construction industry of rail transit is developing rapidly and the industry scale is expanding, but because the construction of rail transit construction projects is very difficult, especially in the wet loess within the concealed excavation tunnel, but also frequent accidents, and the quality of the project is not easy to guarantee, so the underground railroad wet loess within the concealed excavation tunnel construction technology is poor. Therefore, it is especially important to study the construction technology and project quality management of underground railway concealed tunnel in wet loess. In this paper, based on the in-depth study of the basic principle of quantum particle swarm optimization calculation and the realization of key engineering technologies, the particle swarm optimization algorithm is programed using MATLAB software, and the coding scheme, operation specification, and operation parameters are designed. Then, combined with the particle swarm optimization algorithm and assisted MATLAB software, the main analysis of the construction and quality control of wet loess in concealed tunnels of subway projects was carried out, mainly by systematizing the relationship between the three major elements of subway project schedule, cost, and management and the construction and quality control of wet loess in concealed tunnels of a subway, and concluded that the construction and quality control of wet loess in concealed tunnels of the subway needed schedule. It is concluded that the construction and quality control of subway wet loess tunnel requires stable schedule, adequate cost budget, and management personnel.
