2.6 Worked Example 2.4

Design OSD for a hypermarket in Kuala Lumpur.

Total area is 40,000 m2.
Assume that 80% of the surface area is impervious and the rest pervious.

The times of concentration are as follows:
tc= 10 min (factory site outlet)
tcs= 5 min (roof and property drainage)

Assuming a composite storage with 40% above ground storage and 60% below ground storage.

2.2 - 1085 cu m
2.3 -2365 cu m
2.4 - 899 cu m

[richardobc]

our ssr is 926 cubic metre.

[chunboonlee]

Above ground SSR is 335m3 and below ground SSR is 581m3. Total SSR is 916m3.

[ho kiat yee4]

MAXIMUM SSR for a composite storage with 40% above ground storage and 60% below ground storage = 916.4 m3

Worked Example 2.2 (OSD In Ipoh)
Answer :
SSR above ground = 1020.8 m3.
SSR below ground = 1124.5 m3.

Worked Example 2.3 (OSD in Penang)
Answer :
SSR above ground = 1989.9 m3.
SSR below ground = 2156.4 m3.

Worked Example 2.4 (OSD Kuala Lumpur)
Answer :
40 % SSR above ground = 340.1 m3.
60% SSR below ground = 585.92 m3.

SSR = Site Storage requirement

From : Group 1

[shahfizan_4]

SSR Above Ground Storage = 340 m3

SSR BelowGround Storage = 586 m3

[fazela_ws4]

Our answer;

40% above ground, SSR = 340.1 m3
60% below ground, SSR = 585.9 m3

:D

[dzakir4]

40% SSR above ground storage = 335.49m3
60% SSR below ground storage = 580.91m3
