Chapter 17A Special Inspections & Tests
An Overview
• Special Inspections and Tests shall be
provided by “Approved Agencies” employed
by the Owner (& NOT Architect of Record /
Structural Engineer of Record or Contractor):
Responsibility for special inspection belongs
to “Approved Inspection Agencies” and
only indirectly to “Special Inspectors”, employed by the agencies.

2016 CBC: Special Inspections & Tests
• General – throughout the chapter “special
inspector” was changed to “approved
agency.”
The IOR is responsible for verifying the
individual who performs the special
inspections for the approved agency is
accepted by the architect/structural engineer
and OSHPD and is appropriately qualified to
perform the special inspections.

Specified Compressive Strength f’m
• Basic Specified Compressive Strength, f’mis increased to 2,000 psi (from 1500 psi)
• ASTM C90-14: Increased concrete masonry
unit minimum net area compressive strength
to 2,000 psi (from 1900 psi).
Site specific prism tests can be used to justify f’m up to 3,000 psi.

Masonry Core Testing Requirements (Section 2105A.4)
• Core testing requirements for non-bearing
non-shear masonry walls (f’m≤ 2,000psi &
height <12’) built with single-Wythe hollow
unit concrete masonry unit is deleted:
All single-Wythe CMU pass this test.
Original requirements was a qualitative tests
for multi-Wythe masonry, CBC requirement is quantitative and apply to all Masonry.

How does OSHPD deal with Special Inspection of
Pre-Fabricated Equipment/Components Skid?
Depends:
1. Inspector need to be at fabricator’s shop where code requires continuous special inspection.
2. Exception to the CBC 2016 Section 1704A.2 waive inspection requirements for work of minor nature.
3. OSHPD does not require inspection at fabricators shop for components/skids with OSP.
4. Skid with bolts only does not require inspection in accordance with exception to the CBC 2016 Section 1705A.2.
5. Single pass fillet welds up to 5/16” can be inspected in the field (the CBC 2016 Table 1705A.2.1 Item # 5).
