2. Civil Engineering It is the oldest branch of Engineering It came into existence since humans started living in caves. The first invention in civil engineering was something with which one can see through a wall. It is called a window 2 3. Planning of Buildings There are 14 principles of planning as listed below: Aspect Prospect Orientation Privacy Circulation Grouping Roominess 3 4. Principles of Planning Furniture Requirements Sanitation Elegance Economy Access Architectural composition Climate and its Effect 4 5. Aspect:Arrangement of windows in external walls 5 6. Prospect: Desirable and undesirable views 6 7. Orientation 7 8. Privacy External : Isolation from surrounding buildings Avoiding noise, dust and pollution from surroundings Raised sill height of w.c. and bath Compound wall Growing trees around the house 8 9. Privacy Internal : Prevention of direct view of one room from another Staggering of doors Use of screens Proper furniture arrangement 9 10. Circulation Horizontal : On the same floor 10 11. Circulation Vertical : Between the floors 11 12. Grouping Rooms of similar function together More important in Public Buildings Staircase or lift approachable from each room Kitchen w.c. and bath grouped for easy plumbing and watersupply 12 13. Roominess 13 14. Roominess : Chimney Effect 14 15. Roominess :Tunnel Effect 15 16. Furniture Requirements 16 17. Sanitation 17 18. Elegance 18 19. Economy Planning should avoid all type of wastage Wastage of space Judicious use of space Architectural aesthetics for space 19 20. Access 20 21. Architectural composition : Unity 21 22. Architectural composition :Contrast 22 23. Architectural Composition :Scale 23 24. Architectural composition : Proportion 24 25. Mass Composition 25 26. Architectural composition : Form and Function 26 27. Climate and Its Effect Window openings Type of roof Sunbreakers and chajjas External finish, paint and color 27 28. Noise and Acoustics Qualities of sound Noise Comfort level of noise Intensity and Loudness Frequency or Pitch Timbre or Quality 28 29. Measurement of Sound L = K log I1 / I0 Measured in decibels (dB) If L = 1 dB then I1 / I0 = 1.26 Difference in intensities 100 times Loudness 20dB Difference in intensities 1000 times Loudness 30dB Thus the scale of loudness is built 29 30. Sound Insulation For avoiding indoor and outdoor noise Wall insulation Floor insulation Cavity walls Floating floors Use of sound absorbing materials Linoleum, Cork, Carpets etc. 30 31. Sound Absorbent Materials Porous absorbents Resonant panels Cavity resonators Composite type absorbents 31 32. Acoustical Defects Echoes Reverberation Sound foci Dead spots Insufficient loudness Intrusion of noise from outside 32 33. Reverberation time Calculated by Sabines formula Excellent : 0.5 to 1.5 sec Good : 1.5 to 2 sec Fairly good : 2 to 3 sec Bad : 3 to 5 sec Very bad Above 5 sec 33 34. Theatre : Fan shaped plan 34 35. Theatre : Splayed Ceiling 35 36. Sound and Music Studios : Hinged Panels on Shutters 36 37. Building Services Electrical services Telecommunication services Entertainment services Ventilation and Lighting Air-conditioning and heating Lifts and escalators Emergency escape stairs Fire fighting arrangements 37 38. Rain Water Harvesting 38 39. Large Scale System 39 40. New Innovations : Rainpod 40 41.
