CONSTRUCTION PLANT AND EQUIPMENT ASSIGNMENT A contractor is planning to use a tracked dozer with power shift transmission to excavate 1,500 bank cubic meters for the foundation of a large house.

A contractor is planning to use a tracked dozer with power shift transmission
to excavate 1,500 bank cubic meters for the foundation of a large house. The
swell of the excavated material is estimated to be 25%. The dozer must push
the excavated material up a 12% slope where it will be stockpiled for later
removal.
The contractor has measured the pile of excavated material in front of the
dozer’s universal blade just before spillage occurs and has determined the pile

be 4 meters. The dozer weighs 22,200 kgs, and the coefficient of traction is
estimated to be 0.7 The average haul distance is estimated to be 100 meters.
The material is to be disposed to a dump site which is located about 15 Kms
from the site. The Contractor determines that 1,500 meters has a gradient of

How was calacluated 0456 & 0.257?
I will need this notes if you can upload here ?
thank you
❤❤❤
Can I get your power point
Thanks
Leaning more
you are not a teacher ,you are student
Actually I am a professor of construction management 😊
