Triennial Re-Inspection

Triennial Re-Inspection Reports

Re-Inspections of all school buildings containing ACBM or assumed ACBM are required every three years. The inspections are conducted by certified asbestos building inspectors and a report is issued by a certified asbestos management planner.

The most recent Triennial Re-Inspection Report has the most up to date information on the type and location of ACBMs in a school. It is probably the most useful document to have available for reference. The most recent re-inspection reports available are for the 2016 inspection cycle. The 2019 re-inspection has taken place on Oahu. 2019 reports will be issued by late spring/early summer for Oahu. The 2019 re-inspection for Neighbor Islands is pending due to the COVID-19 situation.

The content below summarizes the contents of a Triennial Re-Inspection Report.

This is what a Triennial Re-Inspection report looks like. This one is from 2013. The 2016 report looks similar, as will the 2019 report.

List of School Buildings

The first section of the Triennial Re-Inspection Report is the List of School Buildings.

The List of School Buildings provides a quick reference to see if a particular building has any ACBM. If it indicates "no", that means there was no ACBM found anywhere in the interior of the building. It does not address other hazmat issues, such as lead paint.

Campus Site Plan

The campus site plan shows the layout of the campus, including all school buildings included in the Triennial Re-Inspection Report.

Material Summary

The Material Summary lists each Material ID (also known as Uniform Sampling Area (USA) or homogeneous material) that has been identified as a SUSPECT ACBM. It also includes the school name, the building name or function, a description of the suspect ACBM, whether an ACBM is friable, recommended priority of response action, and the amount (%) of asbestos in the material.

The Material ID provides a unique ID to each suspect ACBM. This is the same as the Uniform Sampling Area (USA).

In this example:

104 = school code

A = Building A

1 = 1st floor

A = alpha list of materials

Building Information Sheet

The Building Information Sheet lists:

  • School code

  • School name and address

  • Building number and name

  • How many floors are in the building and what type of construction materials were used

  • Date the building was inspected and the inspector name and certification information

  • Whether ACBM is present and if there are any exterior suspect ACM

USA Cross-Reference

The USA Cross-Reference sheet is also called the Unified Homogeneous/Sampling Area ACM - Space and Salient Cross Reference.

The USA Cross-Reference sheet lists:

  • Building number and name

  • School address

  • The space identification label (in this example 104-A-1, which means this is for materials on the 1st floor of building A at school # 104).

  • The Unified Sampling Area (USA) label for each USA.

  • A description of the homogeneous material.

  • Any comments about the status of the homogeneous material.

  • Whether the material is suspect ACBM, whether testing has confirmed the material is ACM, No ACM or is assumed ACM or abated.

  • Whether the material is friable ACM

  • What type of ACM material (TSI, surfacing or miscellaneous), if ACM

  • Risk Assessment

    • Damage condition summary

    • Potential for damage

  • Recommended response action priority

  • Estimated cost for removal


Sample Area Report

The Sample Area Report lists the details of each suspect ACBM evaluated in the re-inspection.

This includes:

  • The USA/Homogeneous Material description.

    • Recall the definition of a homogeneous material: An area of ACBM that is uniform in color and texture, and which does not extend to other floors or buildings.

  • The area plan associated with confirmed, assumed or new ACM within the building.

  • The sampling data including how many square feet of all homogeneous material is present on the floor of a particular building (in the example, the sink is estimated at 20 square feet. This suggests there are several sinks with the same color and texture of insulation on floor 1 of building A at school 104).

  • A list of the number of samples taken for analysis and the sample numbers.

  • The number of sample analyzed and the average percentage of asbestos found.

  • Risk assessment.

  • A color photo if the material is present and accessible.

Homogeneous Area Plan

The Homogeneous Area Plan is a diagram that shows where confirmed ACBM is located (by hatching or other patterns) and where samples were taken.

Bold square samples indicate positive for asbestos

Unbolded rounded corner samples indicate negative for asbestos

The Homogeneous Area Plan is the quickest way to identify where ACBMs are located on a particular floor of a particular building.
