The document presents the construction process of a commercial multistory building. It discusses the key steps which are excavation, foundation, columns, column footing, beams, slabs. For each step, it provides details on the types used such as shallow foundations including strip, isolated, combined and raft. It also outlines the salient features of the building including concrete grade, steel grade, bar sizes used in columns, beams and slabs.

- 2. Presentation on seminar topic at Construction process of commercial building SUBMITTED TO:- PRIYANKA PANDAY A.K. MATHUR PERSENTED BY :- LOKESH KUMAR ME Final year (Civil)
- 3. •CONSTRUCTION PROCESS OF COMMERCIAL MULTISTORY BUILDING: EXCAVATION FOUNDATION COLUMN COLUMN FOOTING BEAM SLAB SALIENT FEATURES
- 4. EXCAVATION Excavation is the process by which a part of land is cleared for the construction process after the surveying work has been done. It can be done on the ground level or below the ground level or below the ground level surface by means of machines like excavators, bulldozers and sometimes blasting process is also carried out wherever hard rock is formed.
- 5. Excavation
- 6. Particular hazards identified in relation to excavation work include: •The depth of excavation •The presence of water •Exposure to wet weather •Vibration which may increase the potential to collapse •The presence of existing underground services •Chemical gases
- 7. PLAIN CEMENT CONCRETE Plain Cement Concrete is a mixture of sand, coarse aggregate, and cement. It is used below the footings of any constructional structure, to make the structure stronger and to resist designed load. The main function of PCC is not to allow ground water to enter the footings.
- 9. FOUNDATION :It is that part of a structure which transmits the weight of the structure to the ground. The foundation should be designed such that : the soil below does not fail in shear. The settlement is within the safe limit. Foundation may be broadly classified into two categories: 1.Shallow foundations 2.Pile foundations
- 10. SHALLOW FOUNDATIONS: a shallow foundation transmits the loads to the strata at a shallow depth. If it is laid at a depth equal to or less than its width . Than we consider shallow foundation.
- 11. Types of shallow foundation: •strip foundation •Isolated foundation •Combined foundation •Strap or cantilever foundation •Raft foundation
- 12. PILE FOUNDATION: The ground surface is not capable of supporting a structure , deep foundation are required to transfer the loads to strata.
- 13. COLUMN A column is an element used primarily to support axial compressive loads and with a height of at least three times its least lateral Dimension. the strength of a column depends on the strength of the materials, shape and size of the cross section, length and the degree of positional and directional restrains and its ends.
- 14. TYPES OF COLUMN SQUARE COLUMN CIRCULAR COLUMN RECTANGULAR COLUMN
- 15. SQUARE COLUMN
- 18. COLUMN FOOTING The structural unit constructed in masonry or concrete under the base of a wall or a column which distributes the structure load over a large area of ground.
- 20. BEAMS Beams are horizontal structural element that is capable of withstanding load primarily by resisting bending.
- 21. TYPES OF BEAMS SIMPLY SUPPORTED BEAM CANTILEVER BEAM T BEAM
- 24. T BEAM
- 25. SLAB Slabs are the structural elements used to cover the open space. They usually carry a uniformly distributed load and form the floor or roof of the building.
- 27. TYPES OF SLABS ONE WAY SLAB TWO WAY SLAB
- 28. Long span/short span >2 One way slab
- 29. Two –way slabs Long span/short span < 2
- 30. SALIENT FEATURES CONCRETE GRADE: M20 STEEL GRADE:FE-500 IS BARS ARE USED IN COLUMN: CIRCULAR COLUMN: 32MM RACTANGULAR COLUMN:25MM BARS USED IN BEAM:32MM BARS USED IN SLAB:16MM MORTAR RATIO:1:1½:3 SPACING OF BAR IN SLAB:10MM,8MM
