Chapters 19 and 19A Concrete

California Amendments by DSA and OSHPD

Chapter 19 – Concrete

Office of Statewide Health Planning and Development

1901.3.4 Proof tests for post-installed anchors in concrete

Reorganized for ease of use. Reduced proof test requirements for anchors used for distribution systems and repetitively used architectural components and made consistent with ASCE 41-23. Specified the ASTM standard for tension test procedures.

1903.2 Special inspections

Deleted amendment since this section is deleted in model code. Requirements for special inspections and tests are addressed in Section 1901.6.

1903.3 (formerly 1903.4) Flat wall insulating concrete form (ICF) systems

Relocated amendment to align with model code reorganization.

1903.5 Aggregates

Repealed existing amendment related to alkali reactivity of aggregate as those amendments are incorporated in the body of ASTM C33.

1903.6 Limits on cementitious materials

Repealed existing amendment since revision to ACI 318 and concrete strength requirements at stated ages or stages of construction in model code Section 1901.5 Item # 1 addressed the subject.

1905.5 Detailed plain concrete structural walls

Relocated existing amendments to align with mode code reorganization. Deleted reference to seismic design categories D, E & F.

1906 Detailed plain concrete structural walls

Added an amendment to clarify that only plain concrete footings are prohibited by OSHPD in this section.

1908 Shotcrete

The model code has repealed all shotcrete requirements in favor of those contained in the new version of the adopted material standard ACI 318-19. Added reference to ACI SPEC-560.2 to 1908.1 for clarity.

1910.3.4 ACI 318, Section 26.11.1.2. Item (e)
(formerly 1908.3 Forms and ground wires for shotcrete)

Relocated existing amendment to 1910.3.4 to coordinate with revised model codes.

Division of the State Architect

1909.2.1 Aggregates

Repealed existing amendment regarding alkali reactivity of aggregates.

1909.2.6 Proof tests for post-installed anchors in concrete

Revised DSA-SS/CC to match revisions made to DSA-SS requirements in Section 1910A.5.

Chapter 19A – Concrete

Division of the State Architect and
Office of Statewide Hospital Planning and Development

1903A.5

Repealed existing amendment regarding alkali reactivity of aggregates.

1905A Seismic requirements

As a result of changes to the model code, continuing amendments modifying American Concrete Institute (ACI) 318 formerly in this section have been relocated to Section 1909A.

1908A Shotcrete

Edited and reorganized to align with model code. No regulatory effect.

1909A Modifications to ACI 318 (formerly Reserved)

Moved existing amendments from 1905A to this section.

1910A.5 Proof tests for post-installed anchors in concrete

Reorganized to simplify and clarify test frequency requirements. Updated proof test requirements for anchors used for distributed systems or repetitively used architectural components. Specified ASTM E3121 for tension test procedures without the requirement for displacement measurements unless explicitly required. Reorganized testing frequency requirements to differentiate by structural and nonstructural applications.

1911A.2 Existing concrete structures Crack repair by epoxy injection

Revised specification to the American Concrete Institute (ACI) 548.15 from ACI 503.7.

Office of Statewide Health Planning and Development

1903A.6 Limits on cementitious materials

Repealed existing amendment since revision to ACI 318 and concrete strength requirements at stated ages or stages of construction in model code Section 1901.5 Item # 1 addressed the subject.

1910A.5 Proof tests for post-installed anchors in concrete

Revised testing requirements for screw type anchors to make proof testing easier to implement.
