1. BUILDING CONSTRUCTION Presented By: MAINUDDIN KHAN DepartmentCIVIL

2. Introduction • The term “Building” in civil engineering is used to mean a structure having various components like foundation , walls, column, floors, roofs, doors, windows, stairs, ventilators, lifts etc. • Society requires the building for its various activities as follows; - • Buisness building like Banks, offices, shops, store etc. • Educational building such as school, college, libraries etc. • Health building like hospitals, nursing homes etc. • Industrial building like factories, workshop, mills, gas plant etc. • Transportation building like railway station, bus station, etc. • Worship building like temple, charches, mosques etc.

4. BUILDING CONSTRUCTION COURSE OBJECTIVE Differentiate between the various types of building structures. Identify masonry tools and materials. Identify exterior finish tools and materials. Develop and apply basic skills in exterior finish work. Explore career options in the building construction industry. Identify the range of construction project delivery methods and various roles and responsibilities individuals fulfill within the construction project management process.

7. FOUNDATION • Foundation is also known as substructure of the building. It is the part of a building constructed below ground level and which is in direct contact with sub strata and transmits all the loads to the sub soil. • Types of foundation- deep & shallow

10. TYPES OF BEAM A beam is a structural element that primarily resists loads applied laterally to the beam's axis. Its mode of deflection is primarily by bending. ... Beams are characterized by their manner of support, profile (shape of cross-section), length, and their material.

11. WALLS • Walls are defined as vertical member having length more than four times of its thickness. Used to divide a space into a no. of smaller units in a building. • To provide privacy & security to the occupants. • To protect the occupants from weather condition. • A wall is a structure that defines an area, carries a load, or provides shelter or security. There are many kinds of walls, including: Defensive walls in fortifications. Walls in buildings that form a fundamental part of the superstructure or separate interior rooms, sometimes for fire safety.

13. CHARECTERSTICS OF CONCRETE • Different mixes (M) come in various mix proportions of the various ingredients of cement, sand and coarse aggregates. For instance, M20 comes in the respective ratio of 1:1:5:3. You can see other examples below in the table. • Concrete GradeMix Ratio (cement : sand : aggregates) • Grades of Concrete M5 1 : 5 : 10 • M7.5 1 : 4 : 8 • M10 1 : 3 : 6 • M15 1 : 2 : 4 • M20 1 : 1.5 : 3

14. MORTAR • Mortar is a workable paste used to bind building blocks such as stones, bricks, and concrete masonry units, fill and seal the irregular gaps between them, and sometimes add decorative colors or patterns in masonry walls.

15. The major steps involved in the process of concreting are as follows:1. Batching2. Mixing3. Transporting and placing of concrete4. Compacting.> Batching: The process of measurement of the different materials for the making of concrete is known as batching. batching is usually done in two ways: volume batching and weight batching. In case of volume batching the measurement is done in the form of volume whereas in the case of weight batching it is done by the weight.> Mixing: In order to create good concrete the mixing of the materials should be first done in dry condition and after it wet condition. The two general methods of mixing are: hand mixing and machine mixing.> Transportation and placing of concrete: Once the concrete mixture is created it must be transported to its final location. The concrete is placed on form works and should always be dropped on its final location as closely as possible.> Compaction of concrete: When concrete is placed it can have air bubbles entrapped in it which can lead to the reduction of the strength by 30%. In order to reduce the air bubbles the process of compaction is performed. Compaction is generally performed in two ways: by hand or by the use of vibrators.

17. Conclusion • Durability of a building depend mainly on proper construction process and proper use of materials. • Plaster is necessary to cover and protect the masonry from weathering factor.
