Hot and DryThe hot and dry zone lies in the western and the central part of India; Rajasthan, Madhya Pradesh and Gujarat are some of the states that experience this type of climate.Warm and HumidThe warm and humid zone covers the coastal parts of the country. Some states that fall under this zone are Karnataka, Kerala, Maharashtra, Goa, A.P., Tamil Nadu, West Bengal and Orissa. The high humidity encourages abundant vegetation in these regions.TemperateMysore is the example of city that fall under this climatic zone. Areas having a moderate climate are generally located on hilly or high-plateau regions with fairly abundant vegetation.CompositeThe composite zone covers the central part of India. Some states that experience this type of climate are U.P., Haryana, Bihar, Punjab and M.P.Cold and CloudyGenerally, the northern part of India experiences this type of climate. Most cold and cloudy regions are situated at high altitudes. Himachal Pradesh, Uttarakhand, Sikkim and J&K are examples of places belonging to this climatic zone.

IAY HOUSES: PRESENT SCENARIO

A detailed study was conducted in different parts of the country and information was collected though survey of more than 800 houses, to record typology, overall condition of the rural houses and changes in the past three to five years.

The detailed study of Thirty one districts viz. Jaipur, Jodhpur, Jaisalmer (Rajasthan); Shivpuri & Jabalpur (Madhya Pradesh); Thirvananthapuram (Kerala), Mahboobnagar & Ananthapuram (Andhra Pradesh); Hawarah & South 24 Parganas (West Bengal); Saharanpur & Basti (Uttar Pradesh); Samastipur / Muzaffrabad, Gaya & Madhubani (Bihar); Bathinda & Amirsar (Punjab); Pithoragarh (Uttarakhand); Kinnaur (Himachal Pradesh); Belgoam, Dharwad & Mysore (Karnataka) and E.K.Hills (Meghalaya), Yamunanagar & Rothak (Haryana), Pune, Aurangabad and Ahmadnagar (Maharastra), North Goa, Raipur (Chhattisgarh) was carried out covering all the five climatic zones of the country.

The survey of more then 775 IAY houses through field survey on the basis of :Typology of housing;

Materials and construction technologies used in foundations, walls & roofs.

OBSERVATIONS

• IAY scheme has been more effective from last three years resulting into social up-liftment.

• Awareness towards better quality of life has increased among themasses.

• The present funding is insufficient to build an IAY house.

• Lack of technical support in house construction.

• RR Stone & bricks are predominantly used for foundations.

• Burnt bricks / stone are predominantly used for walling.

• Country made tiles, Factory made tiles, AC Sheets, CGI sheets, Stone patti, RBC and RCC are used as roofing material.

• Wooden frames, stone frames and prefabricated CC frames have been used for doors and windows.

VARIETIES OF SOIL

1. Gravel: These are small pieces of stone with varied size. Soak a sample for 24 hours in a bucket of water. If it disintegrates, it is not gravel. It is not of much use for mud wall building, but if mixed with sandy clays or clayey sands, it is a good binding material.

2. Sand: It is similar to gravel and is the basic material for construction. It is ideal for wall building mixed with clay, sandy clays, clayey sands or cement.

3. Silt: It is very finely textured soil, so fine that the grains can not be seen. It is not suitable for building purpose.

4. Clay: It is a type of soil that sticks when wet. It becomes very hard when completely dry. Some clays shrink when they are dry and expand when wet, but there are also clays, which do not shrink at all. It is a very suitable material for rammed or compressed works of mud.

5. Black Cotton Soil: Known as week soil and is not good for construction. Pile foundation is recommended for areas having this type of soil.

Sponsored by Ministry of Rural Development, Government of India, New Delhi

6. Organic soil: It is the top layer of the earth, mainly composed of rotting and decomposing organic matters. It is spongy when wet and usually smells of decaying matter. It is dark in colour and damp and is not of any use in construction.

7. Mixture of soil: There are soil combinations available naturally which can be described as sandy clay, clayey sand, clayey gravel and so on. It is necessary to first find out which soils are combined in the mixture and then decide about the utility that depends on the proportion of the combination and their characteristics.

MAKING CONSTRUCTION DISASTER RESISTANT

IN EARTHQUAKE PRONE AREAS

FoundationThe design and construction of foundation

depends on the characteristics of load bearing capacity of the soil / ground. In rocky areas, level the weathered, jointed and fissured rocks by chiseling, in steps of about 150 mm and stepped footing built on it, with the foundation width of 600 mm.

Remove small boulders and level the site but leave large boulders. If the rock is massive, chisel it to roughen the surface and build stepped strip footing.

MAKING CONSTRUCTION DISASTER RESISTANT

IN EARTHQUAKE PRONE AREAS

FoundationIn areas with Black Cotton soil, foundation should

not rest on soil. Take it deeper till harder strata are found. In case of very deep strata of black cotton soil, under- reamed piles foundation or RC pedestal type columns is recommended.

In cyclone and flood-prone areas , the plinth height is to be raised.

TREATMENT AT PLINTH LEVEL

In rocky ground, the seismic band at plinth is not required. Lay damp proof course on the strip foundation as usual. Use cement-sand mortar of 1:3 mix thick or 1 : 2 : 3 concrete 38 mm thick with damp proofing compound, whereas in case of other soils, use RC seismic band.

SEISMIC REINFORCING ELEMENTS IN WALLSThe walls should be reinforced with horizontal seismic

bands and vertical bars. Provide seismic bands at plinth, lintel, ceiling and eave levels and top of gable and ridge walls. All gable walls, whether internal or external, must have the gable band at the top and it should be made continuous with the eave level bands.

Hipped vs. Gable Sloping Roof

The four-sloped Hipped roofs are found to be safer than the two-sloped gable roofs in earthquakes as well as cyclones. The main reasons are:

• Four –slope roof is stiffer than two-sloped roof against lateral loads produced during earthquake and windstorms. The wind pressures and suctions are much less on flipped roofs than the gable roofs, hence are safer.

• The triangular gable ends are unstable, be vertical cantilevers, which are easily damaged under lateral are after.

CYCLONE SAFETY HOOKS

To make the roofs cyclone safe, the roof band, purlins, rafters, battens and tiles should be attached to each other with hooks made of GI wires to resist strong winds. The tiles thus fitted with hooks can resist the wind pressure of 180 to 200 km/hour. These hooks can be manufactured.

RECOMMENDATIONS

1. A methodology to prepare the BPL list to include the real beneficiary should be developed. The list may be cross checked by the officials of Zilla Panchayat / DRDAs before implementation.

2. The BPL list may be updated every after two years. There should also be a provision of including acute BPL beneficiary not included in the approved list.

3. A logo of the IAY along with beneficiary’s name and year of construction must be showcased to identify and popularize the IAY programme.

• Andhra Model may be adopted throughout the country for making the beneficiary’s profile uniform.

5. The cement should be made available at site on subsidized rates to encourage cement mortar / pucca construction instead of mud mortar.

6. The typology of houses is changing in different regions. This can be made uniform with Model type designs for different geo-climatic regions.

7. In majority of the places, the technical capacity is not available and people are using the traditional methods of construction and are not exposed to the innovative and improved methods of construction having inbuilt advantages. e.g. The provision of Disaster Resistant Features (e.g. cycles, landslides etc). This must be strengthened by providing training to labours involved in construction activity.

8. Water and lighting are important for all constructions and the careful planning of these is necessary – a perception that is now better understood than in the past.

9. Rainwater harvesting in a village also has a special significance, especially in areas of chronic water scarcity, accentuated by falling water tables. Roof water harvesting has emerged as an important and practical solution in the villages which can service the kitchen, baths, toilets – something which is rarely done.

10. Lighting is essential in all homes in the villages. But power supply is erratic in rural areas. In inaccessible locations like forest and tribal villages, or desert areas, electrification from the grid is both expensive and invariably not feasible.

11.Solar electrification in India, which has abundant sunshine, is clearly an alternative and has always been the practical option for such regions. Solar lanterns can be made available through rural technology parks.

12.The lack of sanitation facilities in the villages has been a serious concern and the provision of toilets with dwelling units is now accepted as essential. The cost, the design and the availability of the water are factors which determine the construction and equally important, the utilization of the toilets.

13.The Building Centers must showcase various models of sanitary latrines and soak pits or sumps developed by CBRI and other institutions. These include some which use virtually no water and designs which are relevant for different parts of India.

RECOMMENDATIONS

Proposed recommendations for the construction of IAY houses:

Mandatory Requirements

• The houses should be structurally safe to withstand natural disasters such as earthquakes, cyclones and floods etc.

• The masses should be made aware about the techniques, which make the houses safer in the event of natural disasters. Awareness about sanitation facility should also be made.

• The additional fund required in making the houses safer may be partially subsidized and partially be made available in the form of long term loans by the financial institutions.

• To ensure the quality of the construction and adequate utilization of funds, there should be a monitoring system through which the construction work should be monitored by a technical person at block/ district level.
