The division method is as follows: \x0d\ The inspection lot is part or all of the subdivisional work. Inspection lot is the basic unit of acceptance. A subdivisional work can be composed of one or several inspection lots (with the same nature), while a subdivisional work can be composed of several subdivisional work with different properties and contents. For example, there may be 67 sub-projects in foundation and foundation sub-projects. See GB50300-200 1 Unified Standard for Acceptance of Construction Quality of Building EngineeringNo. 1 1. In this standard, there are only unit projects (sub-units) → division projects → sub-division projects, and there is no' single project' mentioned in the title. "Single project" refers to only one unit project with complete function in the approved project. \ x0d \ x0d \ division of inspection lots in architectural decoration engineering \ x0d \ c. 0.9:\ x0d \ 1 For outdoor plastering engineering and outdoor tile engineering with the same materials, technology and construction conditions, an inspection lot shall be divided every 500 ~ 1000 _ same indoor plastering engineering, indoor tile engineering and indoor finishing engineering.

Among them, the reinforcement project (joint) can be implemented according to the current national product standards and related specifications. \x0d\ C.0.7 Roof engineering can be divided into different inspection lots according to the roofs of different floors, but for the roofs of the same floor, inspection lots shall not be divided according to deformation joints and construction sections. \x0d\ C.0.8 Building ground works shall be divided into inspection lots according to floors, construction sections and deformation joints, and the standard floors of high-rise buildings can be regarded as one inspection lot for every three floors. When the single layer area is large, 500_ can be used as an inspection lot. C.0. 1 1 building electrical engineering \x0d\ 1 outdoor electrical installation engineering is divided according to site size, commissioning time and functional blocks; \x0d\ 2 transformer room installation project, the main transformer room and transformer room are each an inspection lot; \x0d\ 3 Power supply trunk line installation works are divided according to the number of power supply sections and cable wells; \x0d\ 4 Equipotential connection of electric power and electric lighting installation works and buildings, the inspection lot shall be divided according to civil construction section, deformation joint and floor; \x0d\ 5 Spare and uninterruptible power supply installation subdivisional work is divided into one inspection lot; \x0d\ 6 The installation works of lightning protection and grounding device, artificial grounding device and grounding body using building foundation reinforcement are each an inspection lot, and the large foundation can be divided into several inspection lots by blocks. Lightning protection downlead installation, buildings below 6 floors 1 inspection lot; The high-rise building is set as an inspection lot according to the interval of pressure circle; Lightning arrester shall be installed on the same roof as the inspection lot. \x0d\ C.0. 12 ventilation and air-conditioning projects shall be divided into inspection lots according to the design system and equipment group, and the inspection lots may be divided according to the specifications, models and quantities for duct fittings manufacturing projects; Equipment installation can be divided into inspection lots according to equipment specification, model and quantity, and pipeline system installation can be divided into inspection lots according to pipeline specification, model and length. \x0d\ C.0. 13 outdoor engineering is uniformly divided into one inspection lot. Aproll, steps, open ditches, etc. Included in the ground inspection lot. 6. Inspection lot subdivisional work can be composed of one or several inspection lots. According to the needs of construction, quality control and professional inspection, it can be divided into floors, construction sections and deformation joints. According to the requirements of construction, quality control and professional acceptance, it is divided into floors, construction sections and deformation joints. \x0d\ Principles for dividing inspection lots of construction projects \x0d\ ① Concrete structure subdivisional work can be divided into formwork, reinforcement, prestress, concrete, existing \x0d\ pouring structure, prefabricated structure and other subdivisional work.
