ICC Soils Inspector EC study plan

ICC Soils Inspector EC · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Site and Soil Evaluation & Soil Classification and Identification

  • Map the exam blueprint into a one-page domain-weight table and rank domains by study hours

  • Define the soil profile horizons and describe the field conditions that indicate each boundary

  • Explain how landscape position, slope, and drainage class influence site suitability for an absorption field

  • List the site and soil properties that must be documented during a preliminary site evaluation

Your checkpoint

A one-page blueprint weight table plus a labeled soil profile sketch with horizon descriptions and drainage-class notes

Week 2

Site and Soil Evaluation & Soil Classification and Identification

  • Perform a textural feel test on at least five practice samples and record ribbon length and grittiness

  • Distinguish structure, consistence, and color terms and apply them to describe a soil pit in writing

  • Interpret depth to a limiting layer and explain how it constrains system siting

  • Identify redoximorphic features and explain what they indicate about seasonal saturation

Your checkpoint

Five completed texture-by-feel practice logs with ribbon length, estimated class, and a written pit description

Week 3

Soil Classification and Identification & Soil Compaction and Field Testing

  • Classify soils into textural classes using the texture triangle and verify against feel-test results

  • Explain the difference between soil texture and soil structure and how each affects permeability

  • Describe the standard proctor compaction curve and define maximum dry density and optimum moisture content

  • Identify field methods for determining moisture content and density in the field

Your checkpoint

A texture-triangle worksheet with ten plotted samples plus a hand-drawn compaction curve labeled with MDD and OMC

Week 4

Soil Compaction and Field Testing

  • Compare sand cone, nuclear gauge, and other density test methods and state when each is appropriate

  • Describe how to prepare and calibrate field density equipment before a test

  • Explain how lift thickness, moisture conditioning, and compaction equipment affect achieved density

  • Interpret passing versus failing density test results against a specified percentage of maximum dry density

Your checkpoint

A field testing method comparison matrix with at least four methods, their uses, limitations, and acceptance criteria

Week 5

Soil Compaction and Field Testing & Code Administration, Inspection and Reporting

  • Sequence the inspection steps for a soil absorption system from excavation through backfill

  • List the observations an inspector must record during each inspection phase

  • Explain the purpose of a percolation or hydraulic conductivity test and the conditions that invalidate one

  • Describe common construction defects and the corrective actions an inspector would require

Your checkpoint

A phase-by-phase inspection checklist covering excavation, placement, and backfill with required observations

Week 6

Code Administration, Inspection and Reporting & Site and Soil Evaluation

  • Trace the code administration process from permit application through final approval

  • Identify the roles of the inspector, installer, and property owner and the authority limits of each

  • Explain how to document a correction notice and a failed inspection with specific code references

  • Describe recordkeeping and reporting requirements for inspection findings

Your checkpoint

A sample permit file package including an application summary, inspection log, and one correction notice

Week 7

Code Administration, Inspection and Reporting & Soil Classification and Identification & Soil Compaction and Field Testing

  • Draft a complete site and soil evaluation report from a hypothetical site description

  • Write inspection findings in objective, code-cited language without opinion or speculation

  • Resolve at least five practice scenarios involving borderline soils or failing density tests

  • Review weak areas from earlier weeks and re-drill the lowest-scoring topics

Your checkpoint

A full practice inspection report with findings, code citations, and recommended actions

Week 8

Site and Soil Evaluation & Soil Classification and Identification & Soil Compaction and Field Testing & Code Administration, Inspection and Reporting

  • Complete a timed full-length practice exam under test conditions

  • Score and categorize every missed question by domain and root cause

  • Re-review the two lowest-scoring domains using condensed notes and flash cards

  • Finalize a one-page quick-reference sheet for field terms, thresholds, and inspection steps

Your checkpoint

A scored practice exam with an error-analysis log and a completed one-page quick-reference sheet
