1. Soil and Slope Stabilization (compaction, embankments, MSE walls, slope protection)
2. Roadway Construction (asphalt placement, grade tie-ins, drainage, utilities)
3. Structure Construction (drilled shafts, structural steel, mass concrete, bridge decks,
falsework)
4. Project Administration (inspection coordination, OSHA safety, field adjustments,
documentation)
5. Concrete Pavement Construction (forms, reinforcing steel, joint sawing, surface
tolerances)
6. Plans and Specifications Interpretation (precedence of documents, figured
dimensions, special provisions)
7. Materials Testing and Quality Control (density tests, Proctor, bolt tensioning, concrete
sampling)
8. Traffic Control and Work Zone Safety (temporary traffic control, loop installation,
OSHA compliance)
9. Documentation and Reporting (daily diaries, as-built records, non-compliance
reporting)
,10. Contract Compliance and Field Modifications (change orders, differing site conditions,
liquidated damages)
NICET Level III Highway Construction Certification Exam
1. During inspection of a compacted aggregate base course, which action provides the
most reliable verification that the material meets the specified density requirement?
A. Visually confirming that the surface appears uniform and tightly knit
B. Measuring the loose pile height before the contractor spreads the material
C. Performing the specified field density test and comparing results to the project
requirement
D. Accepting the lift without testing when the contractor states the material came from
an approved source
Answer: C
Rationale: Field density testing provides objective, measurable evidence that the placed
and compacted material achieves the required density, whereas visual inspection and
verbal assurances are subjective and unreliable . 5
2. When a written figured dimension on a construction plan disagrees with the same
dimension obtained by scaling the drawing, which value governs the work?
,A. The scaled dimension because it reflects the actual drawing geometry
B. The written figured dimension because scaling may be distorted during reproduction
C. The average of the two values to minimize potential conflict
D. The dimension preferred by the contractor after field verification
Answer: B
Rationale: Figured dimensions govern over scaled dimensions because drawings can
be reproduced at different scales or distorted, making scaling unreliable for precise
construction control . 10
3. A white disk displayed on a fire hydrant during highway construction operations
indicates which of the following conditions to the inspector?
A. The hydrant is available for immediate emergency use
B. The hydrant has a pressure rating below the minimum required
C. The hydrant is out of service and should not be relied upon
D. The hydrant has been inspected and approved for contractor use
Answer: C
Rationale: A white disk on a fire hydrant conventionally signifies that the hydrant is out
of service, alerting emergency responders and site personnel not to depend on it for
water supply . 1 8
, 4. When contract documents contain conflicting requirements, which document
generally takes precedence over the standard specifications for project-specific
work?
A. The contractor's shop drawings prepared after award
B. The engineer's verbal clarification given during the preconstruction meeting
C. The special provisions written specifically for that project
D. The general reference manuals cited in the standard specifications
Answer: C
Rationale: Special provisions are project-specific and normally govern over standard
specifications and general documents; the contract's order of precedence should
always be confirmed . 10
5. During embankment construction, density tests repeatedly fail even though the
moisture content appears visually adequate; what should the inspector evaluate first
before rejecting the material?
A. Immediately reject all material from the source pit and require a new supplier
B. Review the contractor's compaction method, lift thickness, and moisture-density
relationship
C. Suspend all earthwork operations until the project engineer arrives on site
D. Increase the compaction equipment pass count without further investigation
