01 Civil Works
1. In the excavation of earthworks, the current pricing table, the pumping fee of the wet earthwork is not included (the previous quota is included), and it is now included in the measure project, that is, the chapter 21 construction drainage, precipitation, and deep foundation pit support. When compiling, don't forget!
2. There is a coefficient for man-machine cooperation in excavation, and there is also a coefficient for wet soil. -0.06 position of the vapor barrier;

22. Calculation of concrete of the lintel template of the structural column circle;
23. a fast and easy closing net set up when pouring different concrete grades;
24. Some code requirements are also easy to miss, such as: when the wall length is more than 5 meters, a structural column should be added, and a pressure beam should be added when the wall height is more than 4 meters;
25. The concrete flanging on the wall such as the bathroom (of course, this kind of division is a problem, and the uncounted part is often included in the wall, but this is an eye-catching problem in the preparation of the list);
26. There is no detailed layout drawing, but the items mentioned in the drawing description. Such as structural columns of infill walls, masonry reinforcement, etc.;
27. It is easy to leak the metal heat conduction pipe set in the large-volume concrete;
28. The negative reinforcement distribution of the plate is easy to leak, because the drawings do not reflect it at all;
29. There is another thing in the steel frame that is easy to forget, that is, the stool used to support the steel bar, which is also a large number in the actual construction, and it is very annoying;

61. The line pressure around the roof gusset is easy to miss;
62. When doing decoration, the list items are mostly calculated according to the finished surface. Many projects seem to be complete, if you don't carefully look at the design drawings and construction specifications and bidding documents, it is easy to miss the calculation, resulting in an unreasonable list price;
63.

02 Installation section
1. Lighting costs in basement projects;
2. The labor cost of lighting construction in the cave and basement will be increased by 40%;
3. The list of cables, wires, etc. only provides the net engineering quantity, and the length of reservation, bending, and loss must be added when the price is assembled;
4. In the distribution cabinet installation list, the basic steel is easy to leak;
5. The wire box in electrical engineering is easy to leak;
6. The installation cost of lighting system lamps and lanterns and its system debugging are easy to forget;
7. Plugging the wall casing of the process pipeline;
8. The purging of indoor pipeline installation is easy to miss;
9. Ultra-high cost of outdoor pipeline installation;
10. The casing is easy to leak in the pipeline installation list for water supply and drainage;
11. The cost of production and installation of angle steel and its main materials;
12. Projects that are easy to be left behind in HVAC engineering:
- 1) Insulation of air conditioning duct valves, static pressure boxes, and fan coil return air boxes;
- 2) Flange in the connection between the equipment body and the pipeline;
- 3) civil piers in the pipeline of the roof water system;
- 4) Vibration damping measures adopted by the terminal equipment.
13. a canvas interface installed in a ventilation duct;
14. Blocking of air duct through the wall;
15. Amortization of equipment installation and hoisting equipment;
16. Bracket production, installation, and paint anti-corrosion during equipment installation and pipeline installation with horn and pipeline;
17. The bolts installed by the flange in the process pipeline installation are unpriced materials;
18. Production and installation of temporary short pipes for pressure test flushing of control valves;
19. The cost of scaffolding used in the installation of tall workshops, and the general steel structure does not erect scaffolding;
20. Non-destructive testing costs for steel structure welding;
21. In the interface between pipeline and automatic control, the source component may be overcalculated;
22. The price of the main material in the installation project;
23. Scaffolding costs for outdoor process pipeline installation;
24. The erection and dismantling of scaffolding is easy to miss;
25. Installation part: The base of the calculation of the increase cost of high-rise buildings includes all labor costs below 6 floors or 20m. When the high-rise building meets the super-high construction conditions at the same time, the high-rise building increase fee and the super-high increase fee are superimposed.
26. The construction organization design directly affects the composition of the measure fee, and the construction according to the specifications is one of the contents of the contract. For example, when bidding, 24-hour continuous construction is considered, and the cost of night construction measures cannot be ignored, and environmental protection costs such as noise cannot be replaced by simple rates. Another example is that the design drawings stipulate the use of PE water supply pipes, but do not explain what measures should be taken for the roofing part. In addition, when the quota does not conform to the specification, the specification shall prevail, because the acceptance shall prevail;
27. The connection between the list items and the sub-items of the subordinate quota cannot be fully grasped (including the rules for calculating the engineering quantity, the work content, etc.). There are calculation rules for quotas and calculation rules for lists, and the two must be consistent.
