2. 1 project name and site conditions
The office building project of Weicheng Science and Technology Center is located in Weicheng District, Xianyang City, which is the service center office building of Weicheng District Private Science and Technology Industry Base. The design unit is China Railway 20th Bureau Architectural Survey and Design Company. The project has completed the planning, approval and construction procedures. The site "three links and one leveling" has been basically completed, the temporary water and electricity on the construction site has been connected by the construction unit, and the preset position of the water and electricity network has been clearly defined; Engineering design and construction drawings have all been completed, and other relevant technical data are complete, which can meet the construction needs.
According to the requirements of the bidding documents of the construction unit, the bidding scope covers all the contents of civil engineering, water, heating and electricity involved in the construction drawing. The construction period is 180 calendar days, and the project quality has reached the "qualified" level after evaluation. 2.2 Architectural design
This project is a five-story frame structure project, and the building plane is basically arranged in a horizontal "I" shape, with a total construction area of 4200m2. The width of the building in the north-south direction is 2 1.3m, and the maximum length in the east-west direction is 52.5m The height of the building is 4.20m on the first floor, 3.6m on the second to fourth floors and 4.2m on the fifth floor. The maximum height is19.7m. The relative elevation of the building is 0.000 corresponding to the absolute elevation determined by the owner on site.
The main indoor and outdoor decoration works of this project are as follows: Exterior wall decoration: All exterior walls of this project are decorated with paint and colored according to the design parts.
