1.BIM Implementation objectives, contents

1.1. Implementation objectives

Project BIM technology uses full life cycle applications from project preparation, BIM modeling, special applications, secondary deepening of design stage application before construction, construction stage application, operation and maintenance management, and formulates detailed organizational plans at each stage to ensure that the project can solve on-site problems using BIM technology, and indeed use BIM technology to implement it, bringing value to all parties to the project.

(1) Use BIM technology to assist each major in deepening the design of and pipeline integration, form a comprehensive design of BIM model for the entire major, and conduct comprehensive coordination and inspection of the entire major, improve the quality and efficiency of deepening design work, and reduce the impact of design problems on construction.

(2) Use the simulateability of the BIM model to simulate the construction processes of complex nodes in various professional construction, and visually briefed to ensure that complex parts can be installed and survive and improve the technical, safety and quality management level of construction.

(3) Closely combines the BIM model with construction site management to achieve on-site management work such as progress, cost, quality, documents, completion delivery, etc. based on BIM, and improve the management level and on-site coordination and management capabilities of various professional subcontractors.

1.2. Implementation content

Based on the analysis of key and difficult points of the construction process of this project and the above-mentioned BIM application goals, the main application points of BIM are sorted out as shown in the figure.

1.3.BIM Application Solution

1.3.1.BIM Solution Business Architecture

BIM Application Solution is For the BIM application solution for the entire construction process developed by enterprises, through the "three ends and one cloud" product architecture, BIM application services are provided to the three levels of personnel in the decision-making level, management level and operation level in the enterprise to meet the multi-level management model of the enterprise. The corresponding diagram of the BIM application solution architecture and the enterprise architecture is as follows:

1.3.2. BIM enterprise-level solution technical architecture

adopts the "three ends and one cloud" architecture collaborative solution.It mainly includes four parts: PC, mobile, web browsing and BIM cloud collaboration;

[PC] mainly realizes the integration of model, progress, quality and safety data. At the same time, according to the project situation, work can be divided into different work tasks according to major and roles, realizing multi-position and cross-regional work collaboration.

[Mobile terminal] is used to collect on-site quality, safety, progress and other issues. It can be synchronized to display on the PC model in real time and synchronized to the web management warehouse.

[web browsing end] The web browsing end belongs to the project management cockpit and is suitable for the BIM center head and corporate leaders. Because for the company leaders, it is possible that they will not pay attention to specific details, but the overall quality, safety, progress and cost of the project are something they must understand. With the management cockpit, the manager can use the
