NICET HCI study plan

NICET HCI · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Plans, Specifications, and Inspection Documentation

  • Read the plan-set legend and title sheet conventions for a typical roadway project and label 20 standard symbols, line types, and abbreviations from memory

  • Convert 10 plan-scale measurements (stationing, offsets, slopes) into field dimensions using an engineer's scale

  • Distinguish between standard specifications, supplemental specs, and special provisions, and write a one-page decision rule for which governs when they conflict

  • Build a blank inspection-daily-report template that captures pay-item quantities, weather, equipment, personnel, and nonconformance notes

  • Match 15 common pay items to their measurement-and-payment spec section (e.g., unclassified excavation, granular base, structural concrete)

Your checkpoint

A one-page 'spec hierarchy + pay-item cheat sheet' with at least 25 verified entries and a blank daily-report form

Week 2

Earthwork, Excavation, and Embankment

  • Explain the difference between clearing/grubbing, unclassified excavation, and borrow excavation, and state the payment basis for each

  • Compute cut-and-fill volumes for 5 cross-section pairs using the average-end-area method

  • Describe field methods for verifying embankment lift thickness, moisture conditioning, and compaction acceptance

  • Identify the correct test method and minimum frequency for density testing of embankment and select backfill

  • Interpret a typical boring log and classify 10 soil samples by USCS group symbol

Your checkpoint

A worked 10-problem earthwork quantity and compaction-frequency worksheet with answers and cited spec sections

Week 3

Earthwork, Excavation, and Embankment & Subbase, Base, and Flexible (Asphalt) Pavement

  • Explain how subgrade acceptance (proofrolling, density, elevation, grade tolerance) gates the start of base placement

  • Sequence the construction of a granular subbase and aggregate base course, listing inspection hold points at each step

  • Calculate in-place density as a percentage of maximum dry density and decide pass/fail against a stated spec threshold

  • State the field acceptance criteria for base course thickness, smoothness, and crown

  • Distinguish subbase from base material requirements in gradation and quality tests

Your checkpoint

A one-page 'subgrade-to-base hold-point checklist' with 12 or more stop points and their acceptance criteria

Week 4

Subbase, Base, and Flexible (Asphalt) Pavement

  • Describe the asphalt batching/plant process and identify the quality-control tests performed on binder and mix at the plant

  • List the field tests for asphalt placement (temperature, mat thickness, roller pattern, density) and the acceptance frequency for each

  • Diagnose 6 common flexible pavement defects (segregation, roller marks, delamination, low density, poor joints, bleeding) and prescribe the corrective action

  • Explain how joint construction (longitudinal and transverse) is inspected and accepted

  • Interpret a mix design (aggregate blend, binder grade, air voids) and connect it to field acceptance

Your checkpoint

A 10-row 'asphalt defect → cause → corrective action' diagnostic table with field acceptance notes

Week 5

Rigid (Portland Cement Concrete) Pavement

  • Sequence PCC pavement construction from subgrade prep through curing, identifying the inspection hold point at each step

  • Explain how slump, air content, and cylinder breaks are sampled, tested, and used for acceptance

  • Describe joint layout (transverse, longitudinal, construction) and what the inspector verifies before and after sawing

  • Apply grade and smoothness tolerances to a set of profile readings and determine acceptance

  • Distinguish between acceptance testing and quality-control testing responsibilities for concrete pavement

Your checkpoint

A PCC pavement inspection flow chart with 10 or more hold points and the test/acceptance criteria at each

Week 6

Rigid (Portland Cement Concrete) Pavement & Drainage, Structures, and Temporary Traffic Control

  • Identify the components and inspection requirements of culverts, storm drains, inlets, and headwalls

  • Explain how trench backfill, bedding, and pipe grade are verified and what causes a rejected installation

  • Describe erosion and sediment control measures (silt fence, inlet protection) and the inspection frequency for each

  • State the requirements for a Temporary Traffic Control zone setup (signing, tapers, buffer space, flagger use) for a typical lane closure

  • Distinguish between permanent and temporary drainage structures and their inspection hold points

Your checkpoint

A combined 'drainage structure + TTC zone' inspection checklist covering 15 or more items with acceptance criteria

Week 7

Drainage, Structures, and Temporary Traffic Control & Plans, Specifications, and Inspection Documentation

  • Interpret a set of project special provisions and identify 8 items that change standard inspection practice

  • Write 3 sample nonconformance reports that document a deficiency, its location, the governing spec, and the corrective action required

  • Reconstruct a TTC taper and buffer-spacing calculation from given speed and lane-width values

  • Review a sample daily report and identify 6 missing or incorrect entries

  • Explain the documentation chain from field observation to final payment quantity

Your checkpoint

Three completed nonconformance reports using a project-specific spec citation format

Week 8

Plans, Specifications, and Inspection Documentation & Earthwork, Excavation, and Embankment & Subbase, Base, and Flexible (Asphalt) Pavement & Rigid (Portland Cement Concrete) Pavement & Drainage, Structures, and Temporary Traffic Control

  • Complete at least 150 timed practice questions across all 5 domains and score 80% or better overall

  • Re-study the two lowest-scoring domains and write a 1-page summary of each

  • Recite the key acceptance thresholds (density, thickness, tolerance, test frequency) for all 5 domains from memory

  • Simulate a full timed exam section under test conditions and review every miss

  • Build a final 'last 48 hours' review sheet of 25 must-know facts

Your checkpoint

A scored practice-exam log with per-domain percentages and a 25-item final review sheet
