 DETAILED INTERN’S ROLE/ RESPONSIBILITY

First Project manager I.K. Singh gave me three days to learn and understand the routine of the project and also connect with engineers, surveyors, office staff, laborers, sub-contractor, etc. then he gave me responsibilities  Site Supervision • Fixing the alignment of the road • Clearing and grubbing of unnecessary materials i.e. topsoil • Earthwork including subgrade preparation • Culvert construction • Site work quality control • Material selection or road construction

 Tests on Material

• Combined Flakiness and Elongation index

• Sieve analysis

Test on cement • Initial and Final setting time  The fineness of cement by dry sieving  Soundness test  Field test

 Test on Concrete



Workability by Slum cone test

• Compressive strength of concrete.



Compaction test on the subgrade, GSB, and WMM



Bitumen Extraction Test



Core cutting Test

Major duties we assigned • Daily meetings • Site works • Administrative works

 Layer of Road

• • • • • • • •

Natural Ground level Subgrade Granular sub-base layer Wet mix-macadam Prime coat Dense Bound Macadam Bituminous concrete mixes Seal coat

Construction of Pipe culvert Steps: 1) Check natural level of stream. 2) If we have to construct culvert on existing site the note down invert level of existing structure (from these to level we finalize invert level of culvert) 3) Mark the site then excavation as per dimension given in drawing 4) Pour concrete up to PCC level. 5) Then lay the pipe 6) Calculate height of first lift 7) Fill concrete up to first lift 8) Then calculate and fill the second lift 9) If distance from top level of road to top of second lift is less than 1.2m then cast 100 mm thick slab 10) Then calculate head wall and fill concrete

 EXPERIENCE GAINED The past two months of my industrial training has indeed been rewarding. I was fortunate to have gained diverse practical skills in road construction, field test application of theoretical knowledge in fieldwork and human relationship. Basically, the experience I gained includes:  I was able to acquire knowledge on what is Road construction and maintenance entails. 

I was able to acquire knowledge in a lot of processes associated with concrete.



I also acquired knowledge in the steps, activities and processes involved in the actual execution of a project.



I was opportune to participate in a lot of decision making meetings in the course of road construction which helped me enhance my mental ability and gave me insight to real life problem solving scenario.



I also had to opportunity to actually supervise an ongoing project. I obtained a practical knowledge of project supervision and management.



I was able to obtain a practical perspective in the rental and purchase of construction equipment.



I was also able to understand more clearly the various functions of work men (masons, service men, iron benders, carpenter etc.) and their corresponding day pay

PROBLEMS ENCOUNTERED (LIMITATIONS)   I would be telling lies if I said my industrial training was hitch free. It was fraught with both seen and unseen problems which include: • The youths of the community were not very cooperative as they were demanding for “development fee” and money for beer almost on a daily basis. • The heavy downpour of rain during the course of the construction work made work really difficult. • Transportation issues. The distance between Natepute (my PG area) and Kalmboli (construction site) was much, causing a very long and boring journey to work on a daily basis. Also, the cost of transportation incurred everyday considering the fact that I was also not being paid monthly salary or allowances, was really on the high side. • Another challenge/ problem encountered was the fact that I was working with a lot of instructors. Due to the fact that I have never worked or been exposed to a working environment where a lot of people are, during my first few weeks I had problem coping with a lot of instructors/engineers. Sometimes, they usually had conflicting views, opinions and say concerning an issue and this usually made me confused. However, as the training progressed I was able to cope with it, thereby making me stronger and helped improve my interpersonal relationships with everyone around me. • Because it was site work, there was usually little or no time to sit down; it was always work under sun as long as work was ongoing. This initially was vey exhausting for me as I was always tired, but with time I mastered the act of standing and walking for hours while work was going on.

 Conclusion The internship has really helped my career as an post graduate student aiming to acquire the post graduate diploma in project engineering and management. During the course of my internship, I had the opportunity to work directly with civil engineers with several years of field experience. I was opportune to witness an actual construction and not just witness it but be an active part of the flexible pavement construction The internship has met most of the objectives, but its success was under our expectations. Practically it has opened my eyes to working life, enlightened me socially, and matured me as an adult to some extent. It has strengthened our technical base and enabled us to integrate theory with engineering practice. Finally, it has given us a clear sense of direction in our future studies and career The internship has helped me to put theories and concepts that I have learnt in my theoretical class to practice. Truth be told, it was interesting seeing what I learnt in my class work in real life.
