Bits of Me - Life
I don't know where to begin with since I just feel like writing something.. So basically I just blurt out anything I feel right now, no second thought.. sincere from the heart...
LIFE, a four letter word that describe your world. Everything you see and feel, experienced through out a definite journey only god knows when to end it.. It is pitiful how we lead our lives as we are too consumed with this material world.. I am too, somehow drowned in it.. but what has it turn myself into? A lonely individual.
We are living in the world where, competition matters, survival of the fittest outweigh everything else, including your morale and values.. uproot you, diminish you bit by bit.. The concrete jungle bounding my everyday life made me to be a a lifeless, rigid robot.. Although I have toughen up my exterior shell, so I can look as if I am ready to face the world, but deep down inside I still have my soft side, cheesy mushy part of me that somehow I am too embarrassed to show to people. I know somehow I am weak.. emotionally dependent.. fragile. I always think that I am insignificant, worthless.. but I do believe every souls god has created has its own purpose and destined for something..
Well, hopefully my destiny god has set for me leads to a happy ending.. =)

Highrise Services Calculation 1
First of all, these are the general information that you have to have.
1. Plot ratio of the site
2. Allowable plinth area of the site
3. Open space of the site
4. Total site area
5. Proposed quantity of floor (does not include the number of basement/s)
Example,
Total site area = 8371.76m²
Allowable plinth area = 60%
Open space = 40%
Plot Ratio = 1:7
Quantity of Floor = 34 storeys
1. Gross Floor Area (GFA)
= Site Area x Plot Ratio
Example,
8371.76m² x 7
= 58602.32m²
2. Plinth Area
= Allowable plinth area x site area
Example,
60% x 8371.76m²
= 5023.06m²
3. Size per floor
GFA / Quantity of floor
Example,
58602.32m² / 34
= 1723.60m² (does not determine the size of basement/s)
* The size per floor usually be determined first based on the space requirements set out by the client.
4. Net Lettable Area (NLA)
GFA - 30%GFA or 70% of GFA
(30% of GFA is the area reserved for services)
Example,
58602.32m² - 30%(58602.32m²)
= 58602.32m² - 17580.70m²
= 41021.62m²
5. Maximum number of occupants
= NLA / area per person
(Let say 10m² per person, please refer Neufert for this)
Example,
41021.62m² / 10m²
= 4102 person
* Number of occupants usually be determined based on the building program and the space planning.
6. Maximum number of occupants per floor
= Maximum number of occupants / Quantity of floor
Example,
4102 / 34
= 410 occupants per floor
7.Number of Car parking space
NLA / Specified number by the local authority
(125 is the number specified by the local authority, in this case it is the number provided by the Johor City Council in the Local Development Plan)
Example,
41021.62m² / 125
= 328 parking
8. Number of Motorcycle parking space
30% x Car parking space
Example,
30% x 328
= 98 parking
*Note that this calculation is just a general guideline, it DOES NOT have to be precisely followed.
Highrise Services Calculation 2
Second of all, these are the general information that you have to have.
1. Proposed quantity of floors
2. Area of every floor
3. Area designated per person
4. Number of occupants
5. Groos Floor Area (GFA)
6. Net Lettable Area (NLA)
7. Number of occupants per floor
Example,
1. 34 storeys
2. 1723.60m²
3. 10m²
4. 4102 person
5. 58602.32m²
6. 41021.62m²
7. 121 person
1. Num. of passengers in one lift cart
75 % x number of occupants
Example,
= 75% x 4102
= 3077 people
2. Num. of passenger in one lift cart within 30 minutes
(30 minutes x 60 seconds x assumed number of person per lift) / 105
(assume 15 people per lift (65kg per person))
Example,
= (30 x 60 x 15) / 105
= 257 people
2. Num. of lift required
Number of person in one lift cart / number of passenger in one lift cart within 30 minutes
Example,
= 3077 / 257
= 12 lifts
3. Size of AHU per floor
(2.5 % x GFA) / Quantity of floors
Example,
=(2.5% x 58602.32m²) / 34
= 43.08m²
4. Plant Room
3% x NLA
Example,
= 3% x 41021.62m²
= 1230.65m²
5. Usage per Floor
Number of occupants per floor x 40 liters
(assume 40 liters per person for 24 hours)
(assume 20 liters for sanitary)
Example,
= 121 x 40 liters
= 4840 liters
6. Usage of water for the whole building
Usage per floor x Quantity of floors
= 4840 liters x 34
= 164560 liters
= 165 cubic / 1.2
= 137.5m²
7. Backup for water supply
(usage per floor x 10 hours) / 24 hours
Example,
=(164560 x 10) / 24
= 68566.67 liters
8. Total water supply
Usage of water per building + backup water supply
Example,
164560 liters + 68566.67 liters
=233126.67 liters
9. Suction tank
1/3 of total water supply
Example,
= 1/3 x 233126.67 liters
= 77708.89 liters
= 78 cubic/1.2
= 65m²
10. Water tank
2/3 of total water supply
Example,
= 2/3 x 233126.67 liters
= 155417.78 liters
= 155 cubic / 1.2
= 129.17m²
11. Fire Fighting
a) Wet Riser Tank
= 45000 liters (2 stage)
1st stage (Basement)
= 1/3 of wet riser tank
= 1/3 x 45000 liters
= 15000 liters
= 15 cubic/1.2
= 12.5m²
2nd Stage (Roof Top)
= 2/3 x 45000 liters
= 30000 liters
= 30 cubic / 1.2
= 25 m²
b) Sprinkler Tank
= 45000 liters
= 45 cubic / 1.2
= 37.5m²
c) Hose Reel Tank
= 45000 liters
= 45 cubic / 1.2
= 37.5m²
*Note that this calculation is just a general guideline, it DOES NOT have to be precisely followed.
