Building Services 2

  1. 1. Building Services 2 Presented by: Ishka Rogbeer Akshay Budia Teoh Beng Way Jenita Hurgobin
  2. 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
  3. 3. What is meant by Vertical Transportation System? Types of Elevator System System Used in Block C Kone 3000s Monospace® ElevatorSystems Electric Geared Drive Gearless Drive Hydraulic Conventional Holeless Roped
  4. 4. 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
  5. 5. 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.
  6. 6. 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
  7. 7. 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
  8. 8. 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 = ?
  9. 9. 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
  10. 10. 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
  11. 11. 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.
  12. 12. 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
  13. 13. 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
  14. 14. Water FM 200 Wet Chemical Carbon Dioxide Sprinklers Heat Detector Smoke Detector Alarm Bell CO2 Discharge Power Room Jockey/Pressure- Maintenance Pump Duty Pump Standby Pump SPK tank HR/WR Tank Pump Room
  15. 15. Landing Valve & Hosereel Breeching Inlets CO2 Cylinders Fire Switches Fire Hose Sprinkler and Wet Riser Control Valves
  16. 16. Description UBBL Requirement Measured Value 1 Result 1 Measured Value 2 Result 2 Hydrant from Building ≥ 6m 5.0m  10.5m  Hydrant to Breeching Outlet ≤ 30m 23.5m  31.0m  Access Road Width ≥ 6m 7.15m  7.25m  Manual Call Point from Floor 1.2m 1.43m  1.41m  Between 2 Manual Call Points ≤ 30m 42.4m  41.9m  Diameter of Hosereel ≥ 25mm 35mm  35mm  Table 3.1: Comparison between UBBL Requirement and Actual Measured Values
  17. 17.  3.4.1 Set-up not according to UBBL  Re-arrange components according to UBBL Vending Machine - Side View Hidden Equipment behind Vending Machine
  18. 18.  3.4.2 No Automatic shut-off for LPG System  Install a LPG leak detector with automatic shut-off  3.4.3 Water Sprinklers used in Library  Replace with Aerosol-K system  3.4.4 No Fire-Resistant Structure in Classrooms  Use Fire-Rated Gypsum Dry Wall  3.4.5 Water Leak in Sprinkler Jockey Pump  Change and replace the damaged parts
  19. 19.  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
  20. 20. 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
