Construction Coordinator 2 Test: Questions & Step-by-
Step Answers
Mechanisms used by pit dry boring machines Correct Answer - Hydraulic
power, rod pusher steel rods, piercing tool
Protecting buried conduit during backfilling Correct Answer - Remove
rocks, backfill all but top 12 inches with sand
Adding drilling fluid when pulling drill string back Correct Answer -
Expand pilot hole diameter, reduce drag on conduit
Action in case of utility cut with fluid-assisted boring machine Correct
Answer - Follow company and equipment safety guidelines
Purpose of electrical grid mats in fluid-assisted boring system Correct
Answer - Operator protection in case of electrical contact
Type of vibratory plow requiring manual conduit guidance Correct Answer
- Modular vibratory plow
Economical use of vibratory plow compared to trenching Correct Answer -
Underdeveloped areas with maneuverable large tractors
Plowing coaxial cable without cable reel carrier Correct Answer - Lay cable
along route, guide into feed chute of plow
Length of starter trench for plowing conduit Correct Answer - Allows
lowering plow blade to burial depth without bending conduit too much
Preferred forward speed of surface dry boring machine Correct Answer -
Speed that allows boring bit to work freely
Purpose of Portable Conduit Fishing System Correct Answer - Used to
blow a pull line through the conduit
Contraction of 1200 ft Conduit Correct Answer - 36 inches
, Direct Burying Coaxial Cable Correct Answer - Avoid reverse bending of
the coaxial cable when unreeling
Method for Removing Coaxial Cable from Reel Correct Answer - Pull the
cable from the bottom of the reel on a stand
Removing Large Rock During Trenching Correct Answer - Backhoe may be
required
Digging the Trench Correct Answer - Confirm all utilities have located their
lines first
Inspecting Chain Trencher Correct Answer - Check for loose bolts, broken
chain teeth, or fluid leaks before operation
Boom on Chain Trencher Correct Answer - Spring-loaded to create tension
on the chain
Backfilling the Trench Correct Answer - Use gravel, soil stabilizer, or slurry
mixture for proper compaction
Factors for Total Length of Pre-Assembled Cable Correct Answer -
Consider thermal expansion contraction allowance
Checking Physical Network Integrity Correct Answer - Observant and
performing minor tasks during regularly scheduled activities
Analyzing Network Design Maps Correct Answer - Device common to
affected customers for signal status checks before traveling
Test Instrument for Cable Faults Correct Answer - Time Domain
Reflectometer TDR
Splicing into Hardline Coaxial Cable Correct Answer - Power Inserter for
combining AC power with RF signal in HFC network
Identifying Distribution Amplifier Correct Answer - Multiple downstream
outputs on the distribution amplifier
