![Page 21: Chumey technical training institute bumthang bhutan](https://reader031.vdocument.in/reader031/viewer/2022012320/55a6847d1a28ab2b498b47fe/html5/thumbnails/21.jpg)
Estimation and costing
Raw material used is M.s Pipe of outer dia 50 mm
Tie beam= 1 x 20 m = 20 m
Top chord = 2 x 11.18 = 22.36 m
King post = 1 x 5= 5 m
Vertical studs = 2 x 3 m = 6 m
= 2 x 1.5 m = 3 m
Total length = 20 + 22.36 + 5 + 6 + 3 = 56.36 m
Consider Wastage = 5%
Therefore, wastage = 5% of 56.36 m = 2.818 m
Therefore total length = 56.36 + 2.818 = 59.178 m
As per steel standard, for outer dia. of 50 mm, the weight is 4.07 kg/m
Therefore weight = 59.178 m x 4.07 kg/m = 240.85 kg
![Page 22: Chumey technical training institute bumthang bhutan](https://reader031.vdocument.in/reader031/viewer/2022012320/55a6847d1a28ab2b498b47fe/html5/thumbnails/22.jpg)
Raw material used is M.s pipe of dia 48mm
Inclined member = 2 x 6 m = 12 m
= 2 x 3 m = 6 m
Total length = 12 + 6 = 18 m
Wastage= 5%
Therefore, 5% of 18 m = 0.9 m
Total length = 18 m + 0.9 m = 18.9 m
As per standard weight for outer dia. 48 is 3.61 kg/m
Weight = 18.9 x 3.61= 68.229 kg
Total weight = 240.85 + 68.229 = 309.079 kg
Rate for ms pipe is Rs. 69/kg
Therefore, material cost for one truss = 309.079 x 69 = Nu.21326.451
Therefore, cost of 58 trusses = 58 x 21326.451 = Nu.1236934.158

and dents. Inspect the suspension system for frayed or
broken straps.
If your hard hat needs to be repaired, have it
repaired immediately or ask your employer for a
new one
Never carry personal belongings such as cigarettes,
lighters, or pens in your hard hat
![Page 34: Chumey technical training institute bumthang bhutan](https://reader031.vdocument.in/reader031/viewer/2022012320/55a6847d1a28ab2b498b47fe/html5/thumbnails/34.jpg)
Task-4: Design & Fabrication of window grills
Processes:
Measure the MS strip to the given dimensions of the drawing.
Cut the MS strip as per the measurement
Grind the sharp edge of strip by hand grinding machine.
Edge preparation
Set up the welding machines to required voltage current.
Welds the job i.e. window grills to the require structure prescribed in the drawing.
Remove the welding spark chips and dirt by sand paper or ambry paper.
Paint the grills with red oxide and make it dry and repeat the procedure for second coating.
Paint the grills by silver paint.
![Page 35: Chumey technical training institute bumthang bhutan](https://reader031.vdocument.in/reader031/viewer/2022012320/55a6847d1a28ab2b498b47fe/html5/thumbnails/35.jpg)
Equipments and raw material used:
M.S strip
M.S electrode (d=2.5mm)
Welding machine
Power saw
Hand grinding machine
Estimation and Costing:
Raw Materials: M.s strip of width x thickness = 15 mm x 3 mm
The total length = 4 x 2 m = 8 m
=4 x 1 m = 4 m
![Page 36: Chumey technical training institute bumthang bhutan](https://reader031.vdocument.in/reader031/viewer/2022012320/55a6847d1a28ab2b498b47fe/html5/thumbnails/36.jpg)
Therefore, total length of strip required for one grill = 8 + 4 =12
m
The volume = L x b x t = 12 x 0.015 x 0.003 = 0.00054 m3
Density of Mild Steel = 7,861.093 kg/m3
Therefore, weight of one grill = volume x Density
= 0.00054 x 7861.093
= 4.24 kg
Therefore, weight of 52 grills = 52 x 4.24 = 220.48 kg
Consider wastage = 5% of 220.48 = 11.024 kg
Therefore, total weight of strips required
=220.48 + 11.024 = 231.504kg
The rate of strip = Nu. 69/kg
The total material cost for grills = 231.504 x 69 = Nu. 15973.77
![Page 37: Chumey technical training institute bumthang bhutan](https://reader031.vdocument.in/reader031/viewer/2022012320/55a6847d1a28ab2b498b47fe/html5/thumbnails/37.jpg)
![Page 38: Chumey technical training institute bumthang bhutan](https://reader031.vdocument.in/reader031/viewer/2022012320/55a6847d1a28ab2b498b47fe/html5/thumbnails/38.jpg)
Task-5: Fabrication of door frames
Process of fabrication:
1. Measure the MS angle to the given dimensions of the
drawing.
2. Cut the MS angle as per the measurement
3. Grind the sharp edge of angle by hand grinding machine.
4. Edge preparation
5. Set up the welding machines to required voltage current.
6. Welds the job i.e. door frame to the require structure
prescribed in the drawing.
7. Remove the welding spark chips and dirt by sand paper or
ambry paper.
8. Paint the door frame with red oxide and make it dry and
repeat the procedure for second coating.
9. Paint the door frame by silver paint.
![Page 39: Chumey technical training institute bumthang bhutan](https://reader031.vdocument.in/reader031/viewer/2022012320/55a6847d1a28ab2b498b47fe/html5/thumbnails/39.jpg)
Raw Materials and equipment used:
1. M.S Angle iron 50x50x5mm
2. M.S electrode (d=2.5mm)
3. Welding machine
4. Power saw
5. Hand grinding machine
Estimation and Costing:
Raw Materials: M.S angle iron = 50 x 50 x 5 mm
The total length = 2 x 3.5 m = 7 m
= 2 x 1.5 m = 3 m
![Page 40: Chumey technical training institute bumthang bhutan](https://reader031.vdocument.in/reader031/viewer/2022012320/55a6847d1a28ab2b498b47fe/html5/thumbnails/40.jpg)
Therefore, total length of angle iron required for one frame=7 + 3
=10 m
The volume = L x b x h = 10 x 0.05 x 0.005 = 0.0025 m3
Density of Mild Steel = 7,861.093 kg/m3
Therefore, weight of one frame = volume x Density
= (0.0025 x 7861.093) x 2 since there is two sides
= 39.30 kg
Therefore, weight of 12 frames = 12 x 39.30 = 471.66 kg
Consider wastage = 5% of 471.66 = 23.58 kg
Therefore, total weight of frame required = 471.66 + 23.58
= 495.243 kg
The rate of angle iron = Nu. 69/kg
The total material cost for door frame = 495.243 x 69
= Nu. 34171.767

Conclusion
The summer internship program in the Technical Training Institute Chumey gave me the opportunity to explore new horizon and develop interpersonal skill.
It also gave me the chance to compare college life with real field works despite giving us the room to experiment on new techniques of recent developments.
Introduction of such a curriculum in our degree program would definitely equip the fresh graduates like us to face the world and enable us to perform satisfactory in field.
![Page 42: Chumey technical training institute bumthang bhutan](https://reader031.vdocument.in/reader031/viewer/2022012320/55a6847d1a28ab2b498b47fe/html5/thumbnails/42.jpg)
This training gave us the chance to correlate the subject
knowledge we have learned with the practical
application and gave me the opportunity to explore them.
In fact we got some ideas about the working
environment that will be there for us in future.
It made us to expose to new sets of people and the
relationships.
And most beneficial outcomes of summer training were
the field experiences, skills and the knowledge we got
out of it. It gave us the confidence to be independent and
face the working environment.
