Abstract: Accurately locating the position of the concealed project in the operation and managementstage of the property is a challenge , and some loss of property and incidents of electric shock may occurin the locating process. The visualization of concealed engineering in buildings is proposed. This paperprovides a solution and develops a method to solve the above problems by integrating BIM technology, ORcode technology, and mobile internet technology. A new solution for the concealment of the propertybased on BIM technology is proposed. The new approach could properly solve the locating difficulty andrelated data visualization issue, which could help avoid the economic losses and damages caused by poorlocating of unseen. The new approach will benefit the owners of residences, and also bring great conven-ience during the operation and maintenance management of the property.
