The advantages of the technology are mainly reflected in the implementation, communication, inspection and simulation, etc., to realize the data **** enjoyment and parallel docking, so as to improve the effectiveness of construction management, and promote the continuous improvement of the quality of construction management.

1BIM Technology Overview

Building Information Modeling (BIM) technology is an engineering data model that integrates project information based on 3D technology, and the model is gradually deepened as the project progresses. The technology covers the full life cycle information of the project, from the project design and construction, to the passage of operation and maintenance. The use of 3D synchronized design drawings can be found in the design of unreasonable places, so as to complete the modification in advance to ensure the quality of the design. At the same time, the technology has the characteristics of visualization and informatization, which accelerates the process management and control, ensures the effectiveness of communication, and ultimately realizes intelligent management. In addition, it also has the characteristics of realization and accuracy, which improves the work safety and construction output, and BIM improves the technological content of the construction industry and promotes the development of related industries by combining the 3D technology with the information of the project research and completing the numerical simulation simulation of the building design. Compared with CAD design software, BIM's engineering analysis procedure is more simplified, combined with comprehensive information virtual building model, can be optimized and can be out of the map, more intuitive to find the defects in the project construction. However, the benefits and costs of this technology are relatively unsatisfactory, especially in the domestic technology research and development, still belongs to the groping forward stage. Vigorously promote and use BIM technology, but also need to strengthen the quality of technology and cost adjustment, and increase the survey design and construction technology research and development efforts, in order to shorten the construction period, to ensure the quality of management.

2 BIM technology used in building construction management

2.1 Calculation technology

Technology can be constructed, the full use of arithmetic information, according to the actual situation of automatic identification, based on the nature of the data, statistics of the number of construction. Through the BIM model found to change the design content, need to reflect the content of the change in the schedule, the corresponding construction will also be directly adjusted.

2.2 Three-dimensional collision checking technology

The two-dimensional drawing design can not be found in a timely manner, which directly reduces the construction quality and progress. Through the visualization characteristics of BIM technology, before construction, the pipeline civil engineering and process equipment, such as collision check, can further improve the engineering design, in order to reduce the construction error rate.

2.3 Virtual Technology

This technology can virtualize the process of building renovation, in advance to understand the appearance of the building and the environment, such as functional information, can be carried out in-depth analysis of the architectural design. Especially in the virtual construction, should be in the building model, the physical characteristics of the full reflection, so that the user from all angles to observe the building model. The construction phase of the building is risky, and BIM technology should be used to optimize the construction plan, so as to reduce the error rate in the construction. This technology can analyze the feasibility of the construction plan, so that the management effectiveness is significantly improved [1].

2.44D simulation technology

Construction quality affects more factors, resulting in the construction progress and the actual deviation, with the accumulation of construction errors, the project construction efficiency is directly affected. Through the technology 4D form, can show the construction interface, as well as the construction sequence, according to the actual situation of subcontracting, can realize the effective predetermination of the project progress, as well as the scientific processing of mechanical scheduling. the application of BIM technology directly reduces the risk of resource allocation and construction safety, and realizes the continuous improvement of the quality of construction.

2.5 Data Management Technology

Construction project data is huge, and the system function is cumbersome, the only way to realize the goal of construction efficiency is to strengthen the construction management and ensure the construction quality and safety. Utilizing the information exchange platform of BIM technology, through the *** enjoyment of the project information resources, can reduce the difficulty of construction management, and the management effect is subsequently enhanced. After exporting the information data, the mapping workload is reduced, making the integration and scientific features of construction management gradually enhanced. In particular, the creation of cost data makes the data process more accurate, the cost of data is reduced, and the convenience of staff access to data is improved.

3 Application of BIM technology in construction management

3.1 Deepening design of drawings

Deepening the design of construction drawings can ensure the quality and safety of construction, and provide a value reference basis for construction personnel. However, the deepening design process is complex and cumbersome, need to comprehensively investigate the construction situation, fully grasp the performance of materials, understand the use of equipment and pipeline staggering distribution. Three-dimensional pipeline synthesis based on BIM technology can integrate various specialties into the model and set up the model according to the requirements of the building. Compared with the two-dimensional review form, it is more capable of discovering the collision point of the model, and the effectiveness of deepening the design will be improved.

3.2 cost management

First, it is to collect, *** enjoy cost information data, integration of the whole life cycle of the building, the use of a single model, model information data is relatively complete, storage and other operational difficulties. Secondly, the cost information can be visualized and managed. Linear component management cost information management is not ideal, and cost information management based on BIM technology, through three-dimensional graphic representation of a variety of information. Management method of real-time interaction and simulation of three-dimensional characteristics of the project space parts, as well as various construction time nodes, and their relative cost information can be effectively and truly reflected. As managers, should have a clear grasp of BIM technology, increase the use of modern information technology to improve the efficiency of construction.

3.3 Construction quality management

There are many factors affecting the construction quality, including building materials, machinery and personnel environment and other factors, to improve the quality of construction, but also need to strengthen the management of information technology. Staff use mobile terminal-based BIM technology, real-time understanding of the construction site, so as to take the initiative to avoid the adverse factors affecting construction quality. Construction technicians can use the mobile terminal to browse the model in all directions, and accurately enter the relevant information, and can quickly query the technical standards, and construction programs and other situations. With the distributed cloud platform technology, the defects in the model can be modified in time, and the model can be updated in depth and fed back to the users through the mobile terminal, so that the management efficiency and quality can be improved [2, 3].

3.4 Site optimization management

Construction site management can ensure the safe and efficient development of the project. But in fact, the construction site management content and wide range, including building materials and equipment and other management elements, directly increase the management difficulty. BIM technology can strictly control the building materials and machinery, realize the construction site efficient and orderly management. The use of 5D software, imported building units and engineering site facilities, construction in all phases of the situation can be efficient planning, and can be set up after the specific display of the situation, allowing construction technicians to intuitively understand the dynamics of the construction site, the emergence of construction problems, can be effective measures to deal with, in order to enhance the effectiveness of the management.

3.5 Construction progress management

The traditional method of progress charts to manage construction progress lacks a certain degree of intuition and effectiveness, and potential problems can not be developed in a timely manner to deal with, reducing the effectiveness of management. The use of BIM technology, can be intuitively clear project schedule, reducing the challenge of its construction experience and other aspects. In particular, the introduction of BIM5D software technology can be used to develop a modularized setup of running segments of the project, i.e., divided by district and block. On its basis, the network plan is formulated, and the integration with the corresponding construction model is strengthened to integrate the time dimension information into the model and realize the virtual display of the construction situation, so as to intuitively understand the implementation of the construction plan and narrow the deviation from the actual progress. Based on the BIM technology, the development curve of the project volume, as well as the relevant curve of the project funds, can allow the construction parties to grasp the construction progress, as well as the progress of the project in a timely manner, through effective communication and interaction, to solve the project construction problems in a timely manner, for the construction progress of the project to provide the basis for the guarantee
