  3. 3. Introduction • Name of Project : Multi-Storey Residential Building(G+12) • Company Name : Rajasthan Housing Board • Location of Site : B-2 Bypass, Mansarover, Jaipur • No. of Flats : 93(3-BHK) • Project Start : 15 March 2015 • Project End : March 2017 • Super Built up Area: 185.83 Sq. m(per flat) • Cost per flat : 38 Lakhs • Project Manager : Mr. J.P Chawla
  4. 4. Company Overview • The Rajasthan Housing Board was established on 24th Feb, 1970 due to an RHB Act No. 4, of 1970 by the Government of Rajasthan. • It was Established to provide for measures to be taken to deal with & satisfy the need of Housing accommodation in State of Rajasthan. • The Board consist of a chairman, appointed by The State Government and of six non official members, nominated by The Government .
  5. 5. Unit Plan
  6. 6. Materials Used for Construction Cement: • The function of cement is to combine with water and to form cement paste. This paste sets and binds the aggregate together into a stone like hard mass & thus provides strength, durability . Aggregates: • Aggregates are small pieces of broken stones in irregular size and shapes. Types of Aggregates: Fine Aggregate Coarse Aggregate
  7. 7. Cont.…. Water: • It is an important ingredient of concrete because it combines with cement and forms a binding paste. The paste thus formed fills up the voids of the sand and coarse aggregate bringing them into close adhesion. R.C.C: • Though plain cement concrete has high compressive strength and its tensile strength is relatively low. • So it is reinforced by placing steel bars in the tensile zone of the concrete beam so that the compressive stress is carried by concrete and tensile stress is carried by steel reinforcing bars.
  8. 8. Preparation of Foundation • A foundation is the element of any structure which connects it to the ground, and transfers loads from the structure to the ground. Foundation is a part of the sub structure. Sub structure is constructed according to soil quality at that site. It is of 2 Types; A. Shallow Foundation. B. Deep Foundation A. Shallow Foundation: If soil have good bearing capacity than we use shallow foundation in construction. • Shallow foundations are also called spread footings or open footings. • It is also of different types such as:
  9. 9. Cont.…. • Individual footing • Strip footing • Raft foundation Individual Footing with plinth beam
  10. 10. Cont.…. • B. Deep Foundation: • A deep foundation is a type of foundation which transfers building loads to the earth farther down from the surface than a shallow foundation does, to a subsurface layer or a range of depths. • It is Mainly done by Pile Foundation
  11. 11. Equipment Used Batching Machine: • The measurement of materials for making concrete is known as batching. The machines which used for batching is known as batching machine. Concrete Mixer: • This is a power mechanically operated machine which is used to mix the concrete. It consists a hollow cylindrical part with inner side wings. In which cement, sand, aggregates and water is mix properly.
  12. 12. Cont..… Belt Conveyors: • The process of carrying the concrete mix from the place of it’s mixing to final position of deposition is termed as transportation of concrete. • At site it is done by belt conveyors. Concrete mixer Belt Conveyors
  13. 13. Cont.…. Compactors: • When the concrete has been placed, it shows a very loose structure. Hence, it must be compacted to remove the air bubbles and voids so as to make it dense and solid concrete to obtain a high strength. • At the site , Needle vibrator was used.
  14. 14. Brick Masonary • The bricks are obtained by moulding clay in rectangular block of uniform size and then drying and burning these blocks. Brick masonry easy to construct compare stone masonry. • Less time consuming . • There is no need of skilled labour to construct it. • The bricks do not require dressing and the arty of laying bricks is so simple. • There are Mainly 3 classes of bricks: • Class A • Class B • Class C
  15. 15. Cont.…. Brick work in Mud Mortar: • In this type of brick work mud is used to fill up the joints. Mud is mixer of sand and clay. The thickness of mortar joint is 12mm. Brick Work In Lime Mortar: • Lime mortar is mixer of lime and sand the thickness of joints does not exceeds 10mm. Brick Work In Cement Mortar: • Cement mortar is mixer of cement and sand . • The ratio of cement and sand varies according to construction as in brick masonary it generally kept 1:6.The thickness of joint does not exceeds 10mm.
  16. 16. Bonds Used in Brick Masonary • Mainly, there are 4 types of bonds used in brick masonary. Stretcher Bond : • The bricks are laid along its length in all courses.
  17. 17. Cont.…. Header Bond: • The bricks are laid along its width in all courses. A half and three quarter bat is also used in alternative courses to break the verticality of joints. English Bond: • Alternate courses consist of stretcher and header. A queen closer is put next to quoin header to break the verticality of joints. • Generally such types of bond is provided in walls width is 9 inches
  18. 18. Cont.…. English Bond: Flemish Bond: • It also provides good strength. Stretcher and header is provided in each course alternatively. A queen closer is put next to quoin header in each alternate course to break the verticality of joints.
  19. 19. Plastering • The term plastering is used to describe thin cover that is applied on the surface of walls. It removes unevenness of surface of walls. Sometimes it is use for decorative purpose also. • The thickness of plaster should be at least 10-15 mm.
  20. 20. Building By-Laws • For the construction of any building, certain restrictions are laid down by Municipal bodies, Urban development authorities ,and other government departments as town planning trusts to clear open spaces to be left around the buildings. Plinth Area Regulations: Area of plot Maximum permissible covered area 1 Less than 200 sq. m 66.66 % of the plot area on the ground. 2 201 to 500 sq. m 50% of the plot area or 133 sq. m whichever is more. 3 501 to 1000 sq. m 40% of the plot area or 250 sq. m whichever is more. 4 More than 1000 sq. m 33.33 % of the plot area or 400 sq. m whichever is more.
  21. 21. Cont.…. Open Space Regulations: • Width of street fronting the plot (m) Front open space minimum (m) Upto7.5 1.5 7.5 to 18 3.0 18 to 30 4.5 Above 30 6.0 Rear and Side Open Space: Avg. width = 3 m • At no place less than 1.8 m • Can be reduced to 1.5 m for building ht. <7m
  22. 22. Conclusion • Durability of a building depend mainly on proper construction process and proper use of materials. • As per my training ,I have conclude that , during my training days I was familiar with the construction of brick masonry & plastering and other works under a Rajasthan Housing Board project. • Plaster is necessary to cover and protect the masonry from weathering factor.
