9. PLUMBING LAYOUT
SANITORY PIPING
• System type -1 pipe system.
• Slope -1:100 is maintained.
• Angle of bends -45 deg.
• No of air changes -10 times (as per
NBC).
• Independent floor ventilation system is
adopted.
• Referred NBC-9 for plumbing
design.

10. FIRE FIGHTING
➢ Pipe sizing for the system is
done by referring NBC part-4
“FIRE AND LIFE SAFETY”.
• Table – 09 office buildings.
Table – 23 fixture units for
sanitary appliances. Table –
25, 26 sizing of drainage
pipes.
➢ Sprinklers are placed properly
as per their throw capacity
➢ Sprinkler used:
Dry - pendant –
hosted
