IBC 1705.17 • ASTM E2174 • ASTM E2393
With more than 35,000 inspections and over ten years performing and supervising inspections nationwide, we deliver the most thorough and defensible special inspection reports in the industry.
Required on Every High-Rise and Risk Category III/IV Project
International Building Code Section 1705.17 mandates third-party special inspections for mechanical, electrical, and plumbing penetrations plus fire-resistive joint systems. We are one of the few agencies that has been doing this since before it was code-required.

- Witness minimum 10% of installations per ASTM E2174
- Witness minimum 5% of installations per ASTM E2393
- Destructive examination of minimum 2% of each penetration type (E2174) and 1 per 500 linear feet of joints (E2393)

- Detailed deficiency reports with exact code citations and required remediation
- Final sign-off letter accepted by every AHJ we’ve ever worked with
