Narrow concept: in architecture, the electrical system that uses modern advanced scientific theory and electrical technology (including electric power technology, information technology and intelligent technology, etc.) to create humanized living environment. ) collectively referred to as the scope of building electricity.
The function of building electricity: to serve people's work, life, study, entertainment and safety in the building.
Building electricity includes:
(1) Building high-voltage system: power supply and distribution system, lighting system and grounding system.
(2) Building weak current system: automatic fire alarm system, safety prevention system, equipment automation system, cable TV system, integrated wiring, cable broadcast sound reinforcement system, conference system, etc.
1, the design violates or deviates from the provisions of the design specification, and it is quite common that the design specification is not implemented in terms of safety and credibility. At present, it is quite common that the construction drawing design can't meet the requirements of the Ministry of Construction's "Provisions on the Compilation Depth of Construction Engineering Design Documents". The main reason is that there are defects in the enforceability of design documents, which directly leads to difficulties or mistakes in construction and installation, and may also lead to insufficient usability.
2. The design depth is not enough. Because the necessary calculation and marking are not carried out according to the specified depth, it is often difficult to find the design documents in time because of the wrong principle, which affects the use function of the project.
3, related professional design documents cohesion is not clear, not in accordance with the provisions of the coordination problem is widespread, easy to lead to construction errors. Design documents are the most important basis for engineering construction and supervision. Whether the design can seriously implement the national regulations, the depth of design documents and the close cooperation of related majors will directly affect the engineering quality.
