Mechanical and electrical installation engineering should first ensure the use of the function and safety performance of each profession, where in violation of the mandatory provisions or there are serious safety hazards, the quality of the project is common, are not able to pass the evaluation of the excellent project.
Key parts of installation project planning and implementation monitoring:
Layout planning of the upper space of the lower garage and underground public walkway;
Functional rooms; Toilet; electric wells, tube wells;
installation of roofing equipment, roofing pipes, and lightning protection nets;
Ceiling; fireproof treatment of wood decoration, soft decoration and socket switch;
construction of the bridge; motor inlet processing; Pipe root, support and hanger root treatment; Outdoor grounding test point setting; installation and construction of distribution cabinets and distribution boxes;
application of plumbing, equipment, paint color and identification; Toilet checkpoints, floors and related facilities are handled.
Layout of the upper space of the underground garage and underground public walkway:
In the basement, including the underground garage and the upper space of the public walkway, it is routinely covered with various water, electricity, heating, gas, ventilation, and air conditioning pipes. These pipes are criss-crossed, and most of them are as high as 7~8 layers. Whether the layout is reasonable and beautiful, the secondary deployment should be carefully carried out in the planning of excellence, and the installation and construction should be carried out carefully.
Water, heating, electricity pipelines criss-cross, orderly arrangement.
Functional rooms:
Various computer rooms, such as air conditioners, pump rooms, boiler rooms, power distribution rooms, intelligent control rooms, etc., are the parts that can best reflect the level of technology.
Whether the layout of various pipelines and equipment is reasonable and orderly, and whether the installation process level is fine, will directly affect the operation, normal function and visual effect of the equipment. The safety and rationality of a variety of support and hanger settings and process pipelines should be considered first, and the use function should not be affected for the sake of aesthetics.
It is necessary to consider the elevation orientation of the equipment and the pipeline layout to cooperate with each other, which not only meets the functional requirements, but also meets the aesthetic requirements. The color and logo of various paints, insulation layers, and coatings will also have a great impact on the visual effect, so it is necessary to carefully plan and construct.
The equipment and pipelines of the air-conditioning and refrigeration room are arranged in a neat and orderly manner, and the pipes share a hanger, which is beautifully arranged.

Roof layout: pipes, equipment, lightning protection systems
The roof is a must-inspect place, and many roofs are equipped with equipment such as smoke exhaust and cooling water towers, as well as pipelines, lightning protection, landscape lighting fixtures, etc. In order to consider the beauty of the roof and the perfect function, it is necessary to design twice and have a comprehensive layout. Closely cooperate with civil engineering and roof decoration, unify planning, consider the function of the installation project to further improve the installation project, and also play a good role in the protection of the finished product. You can consider intentionally creating some highlights and making some humanized sketches to play the role of the finishing touch.
The secondary design of roofing pipes, equipment, and lightning protection systems, comprehensive layout, close cooperation with civil engineering, unified planning, and manufacturing highlights, play the role of the finishing touch. The roof lightning protection facilities are bent with the shape of the building, the gusset on the parapet wall is pressed to the top and the stainless steel lightning protection railing, the height and the roof exhaust pipe are fixed to meet the requirements of the specification, and the steel ladder is provided across the partition parapet wall to facilitate maintenance and inspection.
Installation of electric wells and tube wells:
Each layer of electric wells, tube wells are the object of re-inspection during spot checks, in addition to the civil construction should be in place according to its provisions, (construction sequence: the top of the well→ the wall→ installation → ground). The layout and construction of the installation project is also particularly important. Bridges, cables, distribution boxes, busbars, lamps, pipelines, and valves should be arranged in a neat and orderly manner. Planning should be carried out before construction. According to the size of the space of each shaft, the construction drawing is formed reasonably. The unified installation process of each layer is safe and reliable, the process is perfect, and the beauty is durable.
The equipotential grounding is good, the equipment pipeline is well protected at the ground, the fireproof plugging is good, the bus is well installed, the fireproof plugging is tight, and the installation layout is reasonable and vertical;
The bus is well installed and the fireproof plugging is tight; The installation layout is reasonable and vertical.
Toilet Installation:
Toilet utensils, squatting, seated toilets, urinals, switches, sockets, washbasins, floor drains, mop pools, etc., must be closely coordinated with the decoration and jointly planned.
The arrangement of floor tiles and wall tiles is considered together with the installation elevation of the appliances to form a common planning drawing, and then they are constructed according to the determined elevation orientation in order to achieve a beautiful effect.
The installation of the basin sewer pipe is closely coordinated with the decoration and regular, just in the right ground tile joint, the sanitary ware is installed firmly, the elevation is accurate and the decoration is coordinated;
Bathroom walls, floor tiles and partition treatment, wall tiles vertical and horizontal through the switch box in the center of symmetrical installation.
Ceiling installation and construction:
The installation of the ceiling is a must check the link of the Luban Award, the end of the pipeline above the ceiling, in addition to the basement layout requirements, neat and orderly, the bracket is set reasonably, the end of the appliance and the ceiling decoration is a very critical process. When installing pipelines, it is necessary to take into account the places where electrical appliances such as lamps, sprinklers, smoke temperature sensors, horns, cameras, etc., come out, so that when making the ceiling, they can be aligned in the center and do not damage the ceiling keel. Some lamps and lanterns must also be hung to be safe and reliable.
Wood decoration, soft decoration, socket, switch fire treatment: switch, socket box must be flat decorative surface, pipeline must be in place, can not be exposed in the decorative layer, the knot wire must be tight and tin-shabu, insulation and wrapping two layers, the box is best protected with asbestos fireproof board.
