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.

9

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.

10

2016 CBC: 1703A Approvals

11

2016 CBC: Approved Testing and

Inspection Agencies

A testing agency accredited to ISO

17025 shall be deemed to be an

“Approved Testing Agency.” (CBC 2016

Section 1703A.4)

An inspection agency accredited to ISO

17020 shall be deemed to be an

“Approved Inspection Agency.” (CBC 2016

Section 1704A.2)

12

Approved Agency Responsibilities

(CBC 2016 Section 1704A.2.4)

Approved agencies shall keep records of all special

inspections and tests.

The approved agency shall submit reports of special

inspections and tests to the building official and to the

Registered Design Professional in responsible charge.

Note in a majority of OSHPD projects, the RDP in

responsible charge is the Architect and Structural

Engineer of Record.

All reports shall indicate that work inspected or tested

was or was not completed in conformance to approved

construction documents.

13

Approved Agency Responsibilities (Continued)

(CBC 2016 Section 1704A.2.4)

Discrepancies shall be brought to the immediate attention

of the contractor for correction.

If they are not corrected, the discrepancies shall be

brought to the attention of the building official and to the

Registered Design Professional (RDP) in responsible charge

prior to the completion of that phase of the work.

A final report documenting required special inspections and

tests, and correction of any discrepancies noted in the

inspections or tests, shall be submitted.

2016 California Building Code

Major Changes in

CBC 2016

15

Chapter 16A

Amendments in Chapter 16A Structural Design

Amendments to Chapter 16A

Structural Design

No major change between the CBC 2013

and CBC 2016.

Brace spacing shall be justified by analysis or test & shall not exceed 12’x12’.

Ceiling support and bracing wires shall be spaced a minimum of 6” from pipes, ducts, conduits and equipment that are not bracedfor horizontal forces.

18

Section 1616A.1.19: Prequalified Post-Installed

Anchors and Specialty Inserts in Concrete & Masonry

1616A.1.19… prequalified post-installed

anchors… now includes specialty inserts.

Also, screw anchors in concrete and

masonry shall not be used in building enclosures (exterior walls).

19

Amendments in Chapter 17A Special Inspections and Tests

20

Special Inspection at Fabricator’s Shop(Section 1704A.2.5)

• Special inspection of the fabricated items

shall be performed during fabrication.

Special inspections during fabrication are

not required where the fabricator maintains

approved detailed fabrication and quality

control procedures.

Approval shall be based upon review of

fabrication & quality control procedures and periodic inspection.

21

Modular Structures/Equipment Skids can use

Fabricator’s Shop Exception (Section 1703A.6)

• Modular Structures/Equipment Skids can use

Fabricator’s shop exception to avoid certain

on-site quality assurance inspection.

22

Does OSHPD Consider Manufactured

Equipment to be Fabricated Items?

• In general, NO!

• Fabricated Item ONLY include structural elements, components, supports, and attachments for which structural provisions of the CBSC require Quality Assurance/Quality Control (QA/QC), as defined in the CBSC 2016 Section 1702A.1.

• Manufactured equipment which are not subject to QA/QC by structural provisions of the code are not considered to be fabricated item for the CBC 2016 Section 1704A.2.5: Pump is not considered a fabricated item;

Skid mounted pump assembly will be considered a fabricated item (since skid requires QA/QC)

23

Quality Assurance Vs. Quality Control

24

Quality Assurance (QA). Special Inspections and

testing by an approved agency employed by the

Owner. Project specific testing required by

approved construction documents shall be

performed by the approved agency responsible

for Quality Assurance.

Quality Control (QC). Inspections and

materials/functionality testing provided by the

fabricator, erector or other responsible contractor as

applicable.

Typical Split between QA and QC(AISC 341-10)

25

Perform (P) is

equivalent to

Continuous

Inspection.

Observe (O)

is equivalent

to Periodic

Inspection.

Inspectors shall work

Under the Direction of RDP

26

§129825. …Inspectors.

(a) ….the inspector shall act under the direction of the architect or structural engineer, or both, and be responsible to the board or authority.
