2. Location – Selangor
Educational Site
Divided into Block A, B, C, D & E
Reason why we choose Block C
The 2 Building Services System we choose to
analyse are:
The Fire Protection System
The Vertical Transportation System

ElevatorSystems
Electric
Geared Drive
Gearless Drive
Hydraulic
Conventional
Holeless
Roped
5. Definition & Use
Example of Classification: Excellent, Above
Average, Average, Below Average
Factors affecting QoS of Elevator
Number of Passengers
Time of usage, i.e. flexible or unified
Type of building
Number of landings, & total height of building
6. Round-Trip Time (RTT)
The time in seconds taken by a single lift to travel from
ground floor to the top floor, including the probable number
of stops, and return to the ground floor.
Used to calculate the “interval” using the following formula:
The interval is then used to determine the QoS.
7. Calculations for Block C
Total Time Taken
(RTT) in seconds
No of Stops
Time Taken for Door to
Open & Close in seconds
Jenita 237 9 15
Beng Way 137 4 12
Akshay 60 0 11
Ishka 130 3 14
Average 141 4 13
Table 2.1: Data used to Calculate Round-Trip Time
8. From Table 2.1,
RTT with average 4 stops = 141s
Average door closing and opening time = 13s
Time taken from LG to Level 9 back to LG without
any stop = 60s
Calculations using above findings:
Time taken from LG to L9 = 60/2 = 30s
Speed of Lift = (11 x 3.6)/30 = 1.32m/s
Interval = 141/3 = 47s
9. QoS can now be determined using the following table:
Interval/s Quality of Service
25 - 35 Excellent for all type of buildings
35 - 45 Acceptable for offices/educational buildings
45 - 60 Acceptable for hotels/commercial buildings
60 - 90 Acceptable for condos/residential buildings
More than 90 Below average/Poor for all type of buildings
Table 2.2: Interval v/s Quality of Service
Interval = 47s, therefore QoS for Block C = ?
10. In practice, waiting time is three-quarter
the interval = 47 x ¾ ≈ 36 seconds
Current Capacity= 1360kg, 20 persons
Average RTT = 141s (2min 21s)
Total time to open + close = average 13s
11.
12. Type of Installation
Quality of Service (QoS)
for Office Building
ASSUMED QoS for
Educational Building
1 lift for every 2 floors Excellent Above Average
1 lift for every 3 floors Above Average Average
1 lift for every 4 floors Average Below Average
1 lift for every 5 floors Below Average Poor
Table 2.3: Minimum number of lifts in Offices & Educational Building
Block C has 3 elevators operating for a total number
of 11 floors, i.e. 11/3 = 3.67 floors
13.
14. Use same brand, i.e. KONE 3000s Monospace®
Change the following specifications only:
Lift Speed increases from 1.32m/s to 1.8m/s
Capacity increases from 1360kg to around 1600kg
(an additional 3 passengers per lift)
Door opening + closing total time decreases from
13s to 7s, by removing vocals.
15. KONE Travel Master 110
Carry a large number of people
Practically no waiting time
Reduce the amount of crowding
Can be placed in the same physical space as stairs
16.
17. Passive & Active FPS
Passive FPS – Fire-resistant walls, doors & floors
Active requires the use of mechanical & electronic
devices, i.e. Manual Call Points, Smoke & Heat
Detectors, etc.
Main Active FPS in Block C:
Water Sprinklers
Carbon Dioxide Fixed Installation
FM 200 Fire Suppression System
Wet Chemical System

23. 3.4.6 Smoke Detector Seal not removed
Figure 3.17: Sealed Smoke Detector on Level 4 Block C.
- This means that the device is not functioning and
would be unable to detect a fire.
Figure 3.18: Functioning Smoke Detector
- The orange seal has to be removed for it to function.
Remove seal for it to function properly
24. The VTS indeed has some problems, whereas
the FPS had no real problems as such, but
only a few weaknesses.
Best solution to solve the VTS problems –
Improve the specifications of the current lift
Most important problem to be fixed in FPS –
Non-fire-resistant walls in classrooms
