Levelling with Dumpy Level, Theodolite and Total Station - Mr. Shubham Bansal, Assistant Professor, C&EE took this session. Participants were taken in the field and were divided in the groups of four each to give hands on experience on surveying equipment and actual field problem. All the participants were instructed to work on all the three equipment and take the readings accordingly. After working on equipment, they were asked to draw profile diagram according to the readings taken by them. The session concluded with demonstration of one of the practical applications of Levelling to participants and they were instructed to work on the problem of Cut and Fill of Earthwork. Worksheets were provided to participants.
Session 7: Honing Design Thinking & Creativity: Activity Based Learning -
Mr. Lokesh Choudhary was the speaker of this session. His talk insisted upon defining creativity and design thinking which is nothing but perceiving the world in new ways, to find hidden patterns, to make connections between seemingly unrelated phenomena, and to generate solutions. The session observed interesting team building activities which requires one to think out of the box. The feelings of the participants, before and after concluding a seemingly difficult activity were recorded and was brought to a realization that no task is difficult even in work life and just requires dedication and hard cum smart work for accomplishment. The participants applauded and appreciated the final product they could make despite a feeling of fear for the task deep inside. The session concluded with a feeling of achievement among the participants.
Session 8: Hands on Training on test of essential building materials: Cement, Bricks, Aggregates, Interlocking Paver Blocks-
Mr. Lokesh Choudhary was the speaker of this session. The session was dedicated to material testing and precautions one should take while reporting the results of the test.
