“In recent years, with the deepening of the concept of” BIM + “, the practical application of BIM combined with VR technology has emerged
.
Users can wear VR equipment to check the layout of pipelines and the specific situation of collision points in the VR scene, and feed back the image information to the construction and design personnel timely and accurately, which greatly improves the efficiency of pipeline construction
.
Secondly, BIM + VR technology can help construction managers collect field data, correct construction errors in time and optimize construction
.
Virtual reality (VR) technology is a simulation technology that uses computer to produce virtual environment, so as to give people a sense of environmental immersion
.
In recent years, with the deepening of the concept of “BIM +”, the practical application of BIM combined with VR technology has appeared in the field of AECO (architecture, engineering, construction and owner operated) at home and abroad
.
welcome to pay attention to “Tianjin Engineering Management Association” official account, we learn and practice together
.
It has important applications in the fields of design coordination and optimization, information sharing and visualization of engineering projects, This makes BIM a digital management tool for the whole project life cycle
.
Finally, although there are many examples where BIM Technology is used solely for pipeline collision inspection, the clearance and reserved maintenance work space in the later stage of pipeline installation can not be simply determined by the size and other parameters provided by the BIM three-dimensional model
.
The above problems have different degrees of impact on the acceptance of BIM + VR technology in different dimensions, and reflect the three dimensions of technology, organization and environment faced by technology promotion
.
Firstly, Bim and VR technology can establish the construction information safety education system, and use the interactivity of VR technology to demonstrate the potential dangerous scenes in the construction process, such as electric shock, falling from height, mechanical injury, etc., so that the experimenters can identify the hazard sources in advance and improve the awareness of safe construction
.
This BIM + VR based pipeline collision inspection mode saves time and cost, and the principle is clear, simple and easy to understand
.
The expansibility of BIM Technology can be used to combine with VR equipment for advanced and intuitive inspection
. 
” Building information model (BIM) is a data-based tool applied to engineering design, construction and management
.
This technology can realize the integration of building data and information model
.
The combination of VR technology can provide BIM model with an ultimate application form of immersive and interactive multimedia technology, so as to overcome the disadvantages of BIM Technology when applied alone and provide users with better use experience
.
These elements provide a lot of enlightenment for promoting the application of BIM + VR technology[ 1] Zhang Peixing, Ding Xiaoqiang, Xu Tianbai, Wang Xinyuan, Sun Yanan, Liu Shuai.BIM technology in underground pipe gallery construction application [J]
.
BIM+VR technology based on pipeline collision research and application [J]
.
It does not need professionals, saves labor cost and has a certain scientific and technological content
.
The weakness lies in the low visual authenticity of BIM three-dimensional model
.
The advantages of BIM Technology lie in the visualization of project design and construction, information collaboration and sharing, and the management and dynamic control of the whole process of the project
.
BIM + VR technology combines the advantages of BIM Technology construction process visualization, information collaborative sharing, whole process management and dynamic control of the project, and VR technology to provide immersive and interactive user experience
.
It overcomes the disadvantage of low visual performance when BIM Technology is applied alone and provides users with a better use experience
.
It has the characteristics of immersion and interaction
.
Although BIM + VR technology has broad application prospects, it has not been widely used in the industry according to the current adoption degree, for many reasons

.
BIM + VR technology can provide visual and interactive three-dimensional simulation, plan the resources in the construction process in advance, identify the key and difficult processes in advance, facilitate the construction personnel to arrange the construction scheme and master the technical points, and effectively improve the construction efficiency
.
From the perspective of technical standards, there is no detailed technical standard guide for BIM + VR technology, there is no peer technical exchange, and there is no sufficient external motivation; From the perspective of enterprise cost, the realization of BIM + VR technology requires the purchase of VR equipment and the employment and training of relevant technicians, which increases the cost of the enterprise; From the perspective of intellectual property rights, BIM + VR technology related patents lack property protection and insurance clauses; From the perspective of technology itself, the application mode of BIM + VR is not wide enough, and the technical maturity and stability need to be verified

The application of BIM + VR technology in the field of construction management at home and abroad includes construction safety education, selection and optimization of construction scheme, virtual disclosure, simulated construction, etc
