General Engineering ECCC Questions and
Answers 100% Solved
What steps are common to constructing railroads and constructing roads? Clearing and
grubbing; Cut/fill and prep subgrade
If you know X, Y, and Z, what equations do you use to find A, B, and C when designing a road?
A = Z but must be greater than or equal to 4 inches. B = Y-A but if 2" or less, should be
added to the layer above and if 3", should be rounded to 4". C = X - (A+B).
Which three layers of a road MUST be present at a minimum? Surface, Base Course,
Compacted Subgrade.
List the layers of a road from top to bottom. Which are typically the most expensive? Which are
strongest? Surface, Base Course, Subbase, Select Material, Compacted Subgrade. The
uppermost layers are the strongest and typically the most expensive.
What are the three steps of the base camp electrical design process? Determine interior
electrical loads in watts for each building and piece of equipment ; Select generators for the base
camp based on watts; Install distribution system from the power source to the buildings
, What is the rule of thumb for assigning phases to a load with n wires? Load requires n-1
phases (e.g. a 4 wire load will use 3 phases because one of the wires is the neutral)
Electrical Step 1 Formulas Lights/Outlets x Aps x Volts = Watts
Pump x hp x 746= Watts
Watts per room/1000= KW
*motor vs. non motor separate
% Motor Load Formula (Motor Load Total x 100)/ Total Demand Load
Generator Capacity % Motor Load compare to chart for Gen Factor
Total Demand Load x Gen Factor
