GE CCC (Engineering) EXAM STUDY
GUIDE 2024/2025 EDITION.
How does lead and lag effect the overall project?
Lead and lag assist in proper time management and a smooth work flow
during the process.
Predecessors
• Predecessors create a relationship between two tasks.
•There are four conventions to linking tasks
- Finish to Start (FS)
- Start to Start (SS)
- Finish to Finish (FF)
- Start to Finish (SF)
Resources
•Create resources for the project
- Work
- Material
•Assign costs to the resources
•Assign resources to the tasks you have defined
Road Nomenclature
Memorize! GE 118 Slide 28
Through cut - to reduce slope of roadway
Side Hill Cut - reduce curvature of the road
,Shoulder - drainage
Culvert - To prevent erosion
Traveled Way
Fill
Surface or wearing course
Base
Subgrade
Typical Flexible-Pavement Section
Asphalt Pavement
Base
Subbase
Select Material
Compacted Subgrade
Cohesive Soils: PI > ____
PI > 5
Use 90% - 95% Compaction
Cohesionless Soils: PI <= ____
PI < = 5; LL <=25
Use 95% - 100% Compaction
, Aggregate Pavement Design:
Cover Requirements
Rule of Thumb #1
Rule of Thumb #1: Min. Thickness
The minimum thickness for any layer of a road is 4"
A=Z
B = Y-A
C = X - (A+B)
Aggregate Pavement Design:
Cover Requirements
Rule of Thumb #2
Rule of Thumb #2:
Subbase 2" or less, delete and add to Base Layer
3" or more, use minimum allowable thickness
A=Z
B = Y-A
C = X - (A+B)
Facility Pressure: TO Standard
20 psi minimum
120 psi maximum
Standard facility connection for the service connection (TO Standard)
Standard facility connection is a 1 inch pipe for the service connection
Type of valve at Service Connection (TO Standard)
TO standard is to use a 1" Globe Valve at Service Connection
Recommended Pipe Velocity
