PHRC Workshop

PCCA Workshop - IRC 105: Residential Deck Design & Construction

In this one day workshop, we will review the current code requirements for residential deck design and construction. This will include reviewing the new prescriptive design requirements for joists, beams, and post sizing. We will also review the design requirements for stairs and stair illumination. The newly adopted code requirements lay the groundwork for the design of a residential deck. This workshop will give the opportunity to apply the prescriptive requirements to several design examples. Upon completion of this workshop, attendees will know where to find and apply the prescriptive design guidelines set forth in the IRC code books.

After attending this program, attendees will be able to:

  1. Provide an understanding of the deck requirements in the IRC and Pennsylvania’s Uniform Construction Code.
  2. Provide background information on how to inspect for compliance with the IRC for occupant safety.
  3. Provide a basic understudying of the structural performance of decks, why they failed in the past, and how to prevent future failures.
  4. Provide an overview of proper materials and construction methods.

Course Materials

The 2015 International Residential Code (IRC) and a standard calculator are required. Continental breakfast and lunch included.
