2025/2026 ECCC GE NEWEST EXAM
QUESTIONS AND DETAILED CORRECT
ANSWERS | A+ GRADE
What are the 2 levels of quality control? Correct Answer
Unit QC Program
Project QC Plan
What is average daily traffic and design hourly volume for
roads? Correct Answer Average Daily Traffic (ADT): Total
number of vehicles x2
Design hourly volume (DHV): .15 x ADT
Hourly volume = ADT/24 hours
Nodal Time Estimate Correct Answer Early Start / Activity
# / Early Finish
Duration
Late Start / Resource / Late Finish
How do you determine total float? Correct Answer TF = LS
- ES or TF= LF - ES
ex. 7/ 10/ 17
10
12/ / 22
12-7=5 or 22-17=5
Subgrade Placidity Index (PI) determines what? Correct
Answer PI
,The cohesiveness/ less of the soil
CBR < 5 is cohesive less (95% compaction)
CBR > 5 is cohesiveness (90% compaction)
What are project compnents? Correct Answer Time,
Money, Scope
What are the Gantt chart levels? Correct Answer 1 -
Project list
2- Individual project - Master Activities
3 - Individual Project - Construction Activities
What are the components of concrete? Correct Answer 1.
Portland cement
2. Water
3. Aggragate (gravel/crushed stone)
4. Air
5. Admixtures (Sand)
What method cures concrete?
What is a lump test? Correct Answer Hydration: The
method concrete cures
The concrete slump test measures the consistency of
fresh concrete before it sets.
What are the 4 conventions to linking tasks? Correct
Answer Finish to start (FS) = Task 1 finishes, task 2 starts
Start to start (ss) = Task 2 must start when task 1 starts
Finish to finish (FF) = Task 1 and Task must finish at same
time
Start to finish (SF) = Task 2 cannot finish until task 1 starts
, What are the components of non-standard Fixed Bridges?
Correct Answer Bridge superstructure: above deck
Substructure: Below deck
Deck
Stringer
Railing
Peir
Abutment
Wingwall
What are the priorities of Gap Crossing? Correct Answer
1. Existing bridges
2. Detours/ bypasses
3. Repair/reinforcement
4. Tactical bridges (BVLB, Ribbon, REB)
5. Line of communication bridges
What are the types of Airfields and Helipads? Correct
Answer Initial: 1-6 months (unsurfaced, assault, LZ of
opportunity)
Temporary: 6 months - 24 months (rock/ gravel) C-130/ C-
17
Semi-permanent: 24 months + (rear, concrete)
What are the Hasty Airfield Damage Repair (ADR)
methods? Correct Answer 1. Debris backfill crater: Put
debris in hole. No more than 12". Fill to 18" from runway
surface. Fill 3/4" over with crushed stone.
2. Choke ballast over Debris Crater: 3-5" aggregate rock
when debris is not available.
