  1. ASSESSMENT GUIDELINES Houses types There are three types of houses: Pucca Katcha Semi Pucca

  2. PUCCA • Houses with structure in RC Frame with RC sub structure (which means foundation), vertical and horizontal reinforcement, and walls made of block/brick/stone used with cement sand mortar. • If both walls and roof are made of Pucca materials, the house is classified as Pucca. • Pucca wall is made of burnt bricks, stone and cement concrete. • Pucca roof is made of Tiles, Slate, Corrugated Iron, Zinc or other metal sheets, asbestos cement sheets, bricks, lime and stone, stone and RCC and concrete.

  3. KATCHA • Houses made of mud used for walls/roof and/or dry stone masonry, 80% of the Katcha houses have timber frame (columns and beams). Mud roof can be done with wooden panels or wooden beams or CGI Sheets. • If both walls and roof are made of katcha materials, the house is classified as Katcha.

  4. SEMI PUCCA • Houses without RC frame (columns and beams) but with good masonry work with cement mortar and RCC/CGI Roof. • There is no universal agreement of what is the percentage of the material that could define semi pucca. • Example: A house with good brick masonry and RC foundation is considered as semi pucca.

  5. DAMAGE CATEGORY • There are two type of Damages: • Totally Damaged (non-repairable) • Partially Damaged (repairable) The three categories of houses (pucca, katcha and semi-pucca) with similar damages, have different performances when to be repaired or not.

  6. TOTALLY DAMAGED (NON-REPAIRABLE) • Houses that are completely destroyed. • Houses with structural damages. (Please note that there is a big difference between pucca houses and katcha houses. Katcha houses with structural damages cannot be repaired). • Pucca and Semi-pucca houses: when the entire house is damaged from 40% onwards (up to 100%), this is considered totally damaged. See slide no. 09

  7. PARTIALLY DAMAGED • There are two types of Partial Damages; Repairable and Surface damages • Repairable in Pucca house: RC good structure in good condition. Walls can be destroyed or with minor cracks. • Repairable in Semi pucca house: good structure in good condition. Portions of walls can be destroyed (but not corner) • Repairable in Katcha house: minor damages such as small portion of the walls/roof (but never corner cracks). • Surface damages (for the three types of houses): bullets holes in the walls, plasters cracks, broken windows/doors

  8. TOTALLY DAMAGEDNon-Repairable PUCCA Major Structural Damage

  9. PUCCA TOTALLY DAMAGEDNon-Repairable House is not repairable because beams and columns are cracked and not straight. Even if part of the structure is standing, the house is not repairable because the frame (column and beams) are damaged. To repair the roof, you have to dismantle the existing structure and construct it again.(Roof is monolithic structure)

  10. PUCCATOTALLY DAMAGEDNon-Repairable

  11. TOTALLY DAMAGEDNon-Repairable SEMI PUCCA 1. To repair the roof, you have to dismantle the existing structure and construct it again.(Roof is monolithic structure) 2. Crack in corner of the walls • Destroyed connection between walls and ground floor slab • crack in corner of the walls • Damaged beam

  12. SEMI PUCCA TOTALLY DAMAGEDNon-Repairable

  13. SEMI PUCCA TOTALLY DAMAGEDNon-Repairable

  14. TOTALLY DAMAGEDNon-Repairable KATCHA • Roof is collapsed. • The structure cannot be repaired, it must be demolished and newly build • Roof is totally collapsed • Walls cannot be used because they have main cracks (Probably, walls have no foundation). This is not a sound structure to be repaired.

  15. KATCHA TOTALLY DAMAGED Non-Repairable Cracks in corner: structure is not repairable Even with minor cracks in corner, Katcha structure is not repairable Walls are completely detached from wooden frame Wooden frame is not strong and not connected (no diaphragm action)

  16. KATCHA TOTALLY DAMAGED Non-Repairable Cracks in corner: structure is not repairable Even with minor cracks in corner, Katcha structure is not repairable

  17. KATCHATOTALLY DAMAGED Non-Repairable

  18. PARTIALLY DAMAGEDRepairable PUCCA The RC frame is good, brick walls can be re-build The RC frame is good, brick walls can be re-build, the damage is less than 40% of the entire structure

  19. PUCCAPARTIALLY DAMAGEDRepairable

  20. PARTIALLY DAMAGEDRepairable SEMI-PUCCA Good structure in good condition, cracks in walls can be repaired When there is a good structure in good condition, and damage is less than 40% of the entire structure, the house is repairable.

  21. SEMI-PUCCAPARTIALLY DAMAGEDRepairable

  22. PARTIALLY DAMAGEDRepairable KATCHA Roof with partial damage can be repaired Minor damage without affecting the structure of the house. It can be repaired

  23. KATCHAPARTIALLY DAMAGEDRepairable

  24. PARTIALLY DAMAGEDRepairable SURFACE DAMAGE Surface damage that can be repaired Surface damage that can be repaired
