With the current rapid development of computer network information technology, modern science and technology has penetrated into people's daily life, resulting in many new products of the combination of traditional technology and modern information technology. In the construction of intelligent buildings, a large number of modern information technology should be applied in the construction, which not only facilitates people's daily office use, but also brings new challenges to the construction design. Intelligent building is mainly supported by weak current system. Therefore, in the construction of intelligent building, we must strengthen the management of construction quality, strictly control the construction technology and quality of weak current project, so that the construction of intelligent building can meet the design requirements.
