CONSTRUCTION OBSERVATION BULLETIN: ASC Pacific 3WH & 3WHF metal deck

Issue:
ASC Pacific 3WH & 3WHF metal deck ASC Pacific stopped producing their 3W and 3WF, 3” deep metal deck
around January 2014 and started producing 3WH and 3WHF deck with a flute width of 3 7/8” instead of 4 3/4”. Although most properties of the deck are similar the reduced flute width raises issues with minimum edge distance/flute width requirements for welded-headed studs, as well as inserts and anchors, which may be installed into the bottom of the deck.

Background:
On several recent Hospital Construction projects in California the ASC Pacific 3WH or 3WHF deck was substituted. The implication of the substitution extends to welded-headed studs, inserts and anchors (including post installed anchors) specified for supporting utilities that would have reduced capacities in the narrower flutes of the deck. ASC Pacific reports that they have gone back to producing the 3W and 3WF deck profile with a 4 3/4” wide bottom flute as well as the new 3WH and 3WHF deck with the 3 7/8” wide bottom flute.

Conclusion:
Where ASC Pacific 3WH or 3WHF deck was received since January 2014 the structural engineer of record should investigate the compatibility of the deck bottom flute width with weldedheaded stud values as well as all anchors and inserts specified. All other section, and allowable stress properties of the deck should also be verified against project requirements. Any changes or substitutions shall be approved as an Amended Construction Document per Title 24, Part 1, Section 7-153. All future projects shall verify compatibility of the deck with proposed welded-headed studs, anchors and inserts.

DSA Bulletin BU 15-01: Requirements for Use of ASC Steel Deck 3WH and 3WHF Metal Deck With Concrete Fill

The Division of the State Architect (DSA) has issued Bulletin BU 15-01: Requirements for Use of ASC Steel Deck 3WH and 3WHF Metal Deck With Concrete Fill (PDF – 138 KB) to clarify the requirements for using ASC Steel Deck 3WH & 3WHF metal deck with concrete fill.

The clarification was necessary because ASC Steel Deck stopped producing their 3W and 3WF, 3″ deep metal deck around January 2014 and started producing 3WH and 3WHF deck with a narrower flute width of 3 7/8″ instead of 4 3/4″ used in the 3W and 3WF profiles. Although most properties of the deck are similar, the reduced lower flute width raises the following issues:

  • Reduced edge distance for steel headed studs used for composite beam design and lateral load shear transfer.
  • Reduced edge distance for post-installed anchors and cast-in-place anchors (inserts) installed in the underside of the deck.

If you have any questions, please contact your regional office.

ACIA Continues to Provide Educational Services to DGS/RESD in 2015

In continuation of its ongoing contract with DGS, the American Construction Inspectors Association will be presenting its RCI Division II Building Inspector classes to Real Estate Services Department (RESD) inspectors in a 6 week course beginning on Monday, January 12, 2015, in Sacramento. At the conclusion of the training, attendees will take the RCI Examination for their Registered Construction Inspectors Certifications.

RESD inspectors from the Southern California area attended the condensed version of the training at the ACIA Symposium in Long Beach in November, and will be taking their RCI examinations in February.

The ACIA is proud of its tradition of providing educational opportunities for inspectors and construction professionals and welcomes RESD participation in our Registered Construction Inspectors Programs.
