  11. SAFETY INDUCTION PROGRAM IN CONSTRUTION SITE  Personal protective equipment.  Follow environment guidelines.  Keep the work area clean.  No crowding inside the site perimeter.  Lifting precautions.  Proper site training.  Safety programs & culture.  Risk management system. 11
  12.  Column  It is designed to resist axial & lateral force & transfer them safely to the footing in the ground.  Columns support floors in a structure .  Slabs & beams transfer the stresses to the column so, it is important to design strong columns. 12
  13.  Footing  The bottom part of foundation is called footing .  Footing in construction are critical as the footing distributes the weight of the building evenly across the entire structure so that it doesn't sink into the ground.  The depth of footing is 1m to 1.5m & footing will be designed considering SBC of soil & load from column. 13
  14.  Column starter  Starter is generally a casting of concrete material with equivalent width & length of column section & comparatively smaller height of around 10 cm.  It is casted in such a manner that equal cover is left encircling the reinforcement bars of column & then shuttering of column is provided. 14
  15.  BEAM  Beam is a horizontal structural element that withstand vertical loads, shear forces and bending moments. The loads applied to the beam result in reaction forces at the support points of the beam. The total effect of all the forces acting on the beam is to produce shear forces and bending moment within the beam, that is turn induced internal stresses, strains and deflections of beam. 15
  16.  Column reinforcement  A reinforced concrete column is a structural member designed to carry a compressive loads , composed of concrete with an embedded steel frame top provide reinforcement .  For design purpose the column are separated into two categories : short column & long column 16
  17.  Couplers  Mechanical couplers are the cylindrical element that connect the two rotating edges of reinforcement bars, also known as alternative to lapping rebars,  The grade of coupler should be equivalent to the reinforcement bars which ensures the maximum transmission of the load stresses from one bar to another . 17
  18.  Excavation for footing  Footings are an important part of foundation construction. They are typically made of concrete with rebar reinforcement that has been poured into an excavated trench. The purpose of footings is to support the foundation.  A column or pillar is a structural element that transmits, through compression, the weight of the structure above to other structural elements below Columns are frequently used to support beams or arches on which the upper parts of walls or ceilings rest. 18
  19.  Placing of footing using total station & placing of footing mat  Total station is a surveying instrument combination of electromagnetic distance measuring instrument & electronic theodolite.  It is also integrated with microprocessor, electronic data collector & storage system .  A water foot plastic sheet is laid over the earth. After that, pour around 7 cm layer of plain cement concrete to create a perfectly flat & level base for the foundation .  Lay a reinforcement on spacers over the foundation bed. 19 19
  20.  Placing of footing reinforcement  Reinforcement should be placed @ the tension side @ the bottom of the footing.  In square footing rebars are placed uniformly in both direction.  Shuttering or formwork is the process of giving support & stability to the concrete before it becomes solid.  The shuttering is commonly made using wood & steel. 20
  21.  Placing of concrete using transit mixer & pumping device Transit mixer  Transit mixer is a multipurpose device that used to transport concrete mortar from a concrete batching plant .  The transit mixer is loaded with a dry material & water .  The transit mixer consist of drum with spiral blade which has the ability to move in two direction. Pumping device  A common type concrete pump for large scale construction projects is know as boom concrete pump. 21
  22.  Stair case & retaining wall  The structure containing a stairway a flight if stairs with the supporting framework, casing, & blusters. 22 • A retaining wall is a structure designed and constructed to resist the lateral pressure of soil, when there is a desired change in ground elevation that exceeds the angle of repel of the soil Retaining walls are used for supporting soil laterally so that it can be retained at different levels on the two sides.
  23.  Curing  Concrete sets and hardens as a result of a chemical reaction between cementations materials and water. This process is called hydration. Curing is the process of maintaining satisfactory temperature and moisture conditions in concrete long enough for hydration to develop the desired concrete properties. The potential strength and durability of concrete will be fully developed only if concrete is properly cured. 23

  26.  RMC PLANT  A concrete plant also known as a batch plant is equipment that combines various ingredients to form concrete.  Some of these inputs include water , air , admixtures , sand , aggregates , fly ash , silica fume , slag , & cement . 26
  27.  Plastering  Plastering is a process of covering a rough walls & uneven surface in the construction structures with plastoc materials called plaster .  Ehich is a mixture of lime & cement concrete & sand along with required quality of water . 27
  28.  Over Head Tank  Over head tanks are storage tanks that are built over the head @ a certain height of construction buildings.  The tank may be built of any material but the idea us to achieve maximum efficiency by placing a tank in a some elevated distance . 28
  29.  Vacuum De-Watered Flooring  Vacuum de-watered concrete flooring is suitable for high abrasion & heavy traffic movement .  It is preferably used in making concrete roads , raileay platforms , industrial floors , bridges , RCC roads , pre-cast concrete products etc..  Chemical used for harden floor is Nitoflor hardtop which gives a high performance wprkability admictures , produces a material which monolithically provide dense , non- porous surafce which is extermely hardwearing & abrasion resistant . 29
  30. Nitoflor hardtop used for hardening the floor 30
  31. Brickbat coba water proofing  It is an effective way of providing waterproofing and insulation for thermal comfort for flat RCC roofs to prevent leakage of water.  It is one of the oldest procedures of waterproofing, which consists of laying brickbats on the flat RCC roof and grouting the same with waterproofing compound with a slope to drain the surface water. 31
  32.  Procedure for brickbat coba waterproofing :-  Surface preparation  The slurry is prepared with cement and water to a required consistency. It shall be applied over the dampened surface with brushes very carefully, including the joints between the floor slab and the parapet wall, holes on the surfaces and joints of pipes in masonry or concrete.  Placing of brickbat .  Laying of protective coat .  Curing . 32
  33.  Membrane system :-  A waterproofing membrane is a layer of water-tight material that lies on a surface to prevent water leaks or damages.  The process usually consists of liquid- applied or pre-formed sheet membranes. 33

  35. CONCLUSION  During our internship program we have got a lot of knowledge in terms of improving our practical skill.  The various types of orientation programs, tasks and trainings that we have been undertaking during these past days on the site enhanced our knowledge in building construction. We are very glad to see that what we have learn in the university can be repeated in the working world. We were able to apply our theoretical knowledge of designing and construction works in the real-life situation.  This program played an important role to break the conventional thought that field works can be only implemented by students who hold degree or people who have an experience in building construction. We were able to acquire a high level of confidence to deal with problems arises in constructional works.  We have been able to see the different theoretical aspects, methodologies. We have been fulfilling our curiosity in learning practically building construction well in this internship program.  Generally, the internship program laid sound foundation for us to start our career. We will be definitely sensible to scale this practice up and to replicate it in other disciplines as well 35
