1 AFFORDABLE HOUSING WITH PRECAST CONCRETE TECHNOLOGY
SHEELA ESHWARIAH M.Tech, MBA CHIEF ENGINEER, HOUSING DEPT, TELANGANA

2 Affordable Housing….. 5 times of yearly income @ Rs 20 lakhs…i.e Rs 2500/sft for a house of 800sft Cost of land..?? Cost of construction…?? Rs …../sft

3 Conventional RCC/ masonary
Widely accepted Can make alterations within the frame on a later date for individual requirements More number of conventional contractors More time taking More wastage of material Needs more supervision during execution and finishing

4 Precast technology….. Monolithic RCC/ Composite sections…
Shift from Process quality to Product quality QC in the casting yard QC in transportation, hauling and placing QC in jointing

5 Building design parameters…
Safety Strength… ..against failure from all loads , forces of wind/ earthquake and all moments .. Stiffness……to resist against deformation and dimensional stability. Durability…against vagaries of environment Affordability ….cost Sustainability...??

6 Economical factors… Employment potential Develop local enterprise
Use of indigenous materials

7 Environmental properties

9 Sustainability indicators (39) IS:21929-1
adaptability : ability to be changed or modified to make suitable for a particular use areas of protection : aspect(s) of the economy, the environment or society that can be impacted by construction works, goods or services building : construction works that have the provision of shelter for its occupants or contents as one of its main purposes; usually partially or totally enclosed and designed to stand permanently in one place built environment : collection of man-made or induced physical objects located in a particular area or region. Disposal : <status change> transfer of ownership of, or responsibility for, the object of consideration Disposal : <end of life> transformation of the state of a building or facility that is no longer of use

10 economic indicator : sustainability indicator related to an economic impact
environmental indicator : sustainability indicator related to an environmental impact functional performance : type and level of functionality that is required by stakeholders of a facility, building or other constructed asset functionality: suitability or usefulness for a specific purpose or activity  heat island effect : phenomenon of elevated temperatures in urban and suburban areas compared to their outlying rural surroundings impact category : class representing an economic, environmental or social issue(s) of concern (areas of protection) to which analysis (assessment) results may be assigned indicator : quantitative, qualitative or descriptive measure representative of one or more impact categories

11 indoor air quality : quality of air inside a building, described in terms of odour, chemical and biological pollutants level of functionality : number indicating the relative functionality required for a user group or customer for one topic on a predetermined demand scale from the level of the least (functionality) to the level of the most.  level of serviceability : number indicating the relative serviceability (capability of a facility) for a user group or customer for one topic on a predetermined supply scale from the level of the least (serviceability) to the most life cycle : consecutive and interlinked stages of the object of consideration life-cycle cost,LCC : cost(s) of an asset or its parts throughout its life cycle, while fulfilling its performance requirements life-cycle costing : methodology for systematic economic evaluation of life-cycle costs over a period of analysis, as defined in the agreed scope

12 maintainability : ability to retain a building in a state in which it can perform its required functions or to restore a building to such a state when a fault occurs non-renewable resource : resource that exists in a fixed amount that cannot be replenished on a human time scale performance : ability to fulfil required functions under intended use conditions or behaviour when in use period of analysis : period of time over which life-cycle costs or whole-life costs are analysed renewable resource : resource that is grown, naturally replenished or cleansed on a human time scale

13 serviceability : capability of a facility, building or other constructed asset, or of an assembly, component or product thereof, or of a movable asset, to support the function(s) for which it is designed, used, or required for use set of indicators : non-structured list of indicators social indicator : sustainability indicator related to a social impact stakeholder : individual or group that has an interest in any decision or activity of an organization sustainability indicator : indicator related to economic, environmental, or social impacts system of indicators : structured list of indicators

14 thermal comfort : condition of mind derived from satisfaction with the thermal environment
Note 1 to entry: Thermal comfort is the combined thermal effect of environmental parameters including air temperature, vapour pressure, air velocity, mean radiant temperature (fixed factors) and clothing and activity level of occupants (variable factors). visual comfort : occupant satisfaction with the indoor visual environment, described in terms of illumination level, glare, visibility, reflection and psychological and physiological content with natural and artificial illumination waste : substances or objects that the original holder has disposed of or intends to or is required to dispose of whole-life cost : all significant and relevant initial and future costs and benefits of an asset, throughout its life cycle, while fulfilling the performance requirements whole-life costing : methodology for systematic economic consideration of all whole life costs and benefits over a period of analysis, as defined in the agreed scope

15 Special care required…
Handling and placing of components Adhesive durability Thermal comfort: location of openings No of air exchanges Post operations by Plumbers Safety notices on the event of Earth quakes Safety in electrical wiring

16 Precast technology - requirments
Validation of Design as a unit Performance guarantee Design standards and Quality Manuals Hand hold train to local masons

17 Precast technology - requirments
Development of Design standards and Quality Manuals Development of training packages for professionals and Artisans Development of Maintenance procedures Working out Output norms and rates for Machinery, equipment and labour.

18 Thank You.
