internship report of a civil engineer student

internship report of a civil engineer who worked on a site for 2 month

1. ARBA MINCH INSTITUTE OF TECHNOLOGY FACULTY OF CIVIL ENGINEERIN INTERNSHIP REPORT ON BUILDING CONSTRACTION PROJECTIN BRHANU TOPIYAW CONSTRUCTION PLC BY ABEL SISAY   September ArbaMinch , Ethiopia

2. Introduction This power point discusses on my overall internship program that lasted for about two months in the previous time. Generally there is four main portions:- Overall introduction and Background of the hosting company My overall internship experience Benefits I gained from the internship Conclusion and recommendation

3. Background of the hosting company Brief history of the company Name : Birhan Tobiyaw Building contractor Category : grade one engineering consultant Main office: Addis Ababa

4. Organizational structure

5. The building is 1B+G+8 office and mixed use building Project: Devlopment Bank of Ethiopia Location : Adama Near to Posta Office Owner : Devlopment Bank of Ethiopia Contractor: Birhan Tobiyaw Building Contractor Consultant : Ultimate Plan P.L.C Project information

6. Section of the company I have been working During my stay on the site I have seen and worked on the following: site work and office work. In this presentation I would like to discuss the experience I gained both from the site and office activities.

7. Materials Concrete Concrete is a composite material made up of inert materials of varying sizes which are bound together by a binding medium and the strength of concrete is dependent on the strength of the aggregate-paste bond. Materials for Concrete Mix Cement Aggregate and Water and admixture if any Batching, mixing and placing of concrete spacer

8. Concrete work Used in every RC structure It is a mixture of cement, fine aggregates, coarse aggregate and water Concrete work includes: batching mixing placing compacting and curing

9. Reinforcement work This includes cutting, bending and placing in position of reinforcement as per its design. Stittups : Serve as shear reinforcement and are tied onlongitudinal reinforcement to provide resistance against outward buckling. Z-bar : special bar provided to keep spacing on slab C-bar: used to tie excess bar I beam Lapping: overlap length of bars tied to extend reinforcement

10. Formwork It is temporary construction material used as a mold for a structure with a required size and shape. Requirements of the formwork: Strong enough to resist pressures of fresh concrete ,vibrator , and workman Rigid enough to retain the shape without undue deformation Treated the inside surface with oil The space enclosed must be true size Must be economical

11. Scaffolding It is a temporary structure erected separately from structural support scaffolds. Its purpose is to provide an easy circulation and working environment. scaffolding is required for all type of structure constructed above ground level. Various stages of construction should be erected at convenient heights. Only limited loads should be put on the scaffolding

12. Mobile truck mixer Concrete pumper truck Vibrator Plumb bob Tape Equipment used

13. Man power On the site each employees are their own responsibility, unless those parties stand by on their position the overall activity will be stop. Project manager Site engineer Office engineer Forman Laborers

14. Work task I have been executed Major site works (superstructure) Are activities performed above the ground level.

15. Elevation column It is a concrete structures which transmit the axial loads to the foundations. It is used to carry and transfer loads from slabs, roofs and beams to the foundation. Procedure followed -Provide cretcher -Tie spacer -Keep formwork -Remove the formwork on the next day -Check alignment -Tie bars on starter bars -Cast the concrete - Keep stirrups

16. Shear wall Are types of structures which is vertical elements horizontal force resisting system. It is used to resist lateral load caused by wind and earthquake Procedure followed -Tie starter bars -Provide stirrups -Put spacers -Keep formwork and cast theconcrete

17. Beam It is horizontal member of structure that transfer loads from slab towards column to ensure structural stability. It resist load by means of internal moments. Are two types of primary and secondary Primary beam: runs from column to column and carry major load Secondary beam : runs from beam to beam through the slab Procedure followed -Erect cristy -Tie formwork -Keep + ve and – ve bars -Insert spacer -Check c/c of stirrups -Cast the concrete

18. Slab Slab are a horizontal structure of building which is provide a level surface capable of supporting the occupants of a building, equipment, furniture’s and sometimes internal partitions. Two way solid slab used in my site Steps of construction -Erect H-frame -Arrangement of formwork -Cleaning and painting -Arrangement reinforcement as per design -Provide spacer -Concrete casting

19. Staircase Stairs are used to connect and act as passage between floors. It is used as a way to pass from one floor of the building to another floor part of building . Steps of construction Formwork for carriage Reinforcement arrangement Formwork for riser Spacers provided Verticality of riser checked by plumb bob Concrete added Remove formwork after 21days

20. Major Office work Takeoff sheet : a table format used to compute different amounts of materials such as amount of volume of concrete required, amounts of formworks…… etc Format of takeoff sheet

21. Bar schedule Bar schedule : is a table format which used to calculate total amount of reinforcement bar required for a certain structure

22. OVERALL BENEFITS GAINED FROM THE INTERNSHIP Interms of Improving Practical Skills Upgrading my Theoretical Knowledge Upgrading Interpersonal Communication Skills Improving Team Playing Skills Improving Leadership Skill Entrepreneurship Skill

23. Conclusion Generally from my internship time I know that the following points How to execute a given work How to perform a given task effectively How to solve a problem How to manage a task and time

24. Recommendation For company They should arrange safety tools for site workers specially safety shoe Provide the necessary raw materials Control the vibration of concrete in order to avoid over and under vibration. For university The internship period is not enough to gain necessary knowledge and should be added I recommend that if the university prepare student practicing area in university to practice rather than theoretical learning in addition to internship
