How much is the hotel elevator maintenance premium for one year? There are three elevators and one elevator on the fourth floor.

Charge standard fee = basic fee X( 1+ floor coefficient+enterprise coefficient+speed coefficient+service life coefficient+use place coefficient+origin coefficient-concentration coefficient) (yuan/set/year)

note:

1, floor coefficient: based on 10 floor/10 station, increase by10% every five floors;

2. Enterprise coefficient: on the basis of enterprise qualification of Grade C, Grade B will increase by 1%, and Grade A will increase by 2%;

3. Speed coefficient: ≤ 1m shall prevail. > 1m will increase by 5%, and ≥2m will increase 10%, and above 3m will be discussed separately;

4. Service life coefficient: 10% for ≥5 years, and 20% for ≥8 years;

5. Use site coefficient: public buildings will increase by 20%;

6. Concentration factor: if there are more than 30 sets in the same area, it will be reduced by 5%;

7. Factors of origin: The increasing factors of imports of origin should be discussed separately.
