Washer Standpipes

IPC 406.3 The waste from an automatic clothes washer shall discharge through an air break into a standpipe in accordance with Section 802.4 or into a laundry sink. The trap and fixture drain for an automatic clothes washer standpipe shall be a minimum of 2 inches in diameter. The automatic clothes washer fixture drain shall connect to a branch drain or drainage stack a minimum of 3 inches in diameter.

This means the washer standpipes must drain into a vertical 3 inch stack if you are building an Apartment or Condo, care must be taken to make sure the framing members are 2x6 walls in these areas.

Multi-Family Floor/Ceiling Assemblies

2003 IBC Section 1207 requires a minimum STC=50, and a minimum IIC=50, at floor/ceiling assemblies separating dwelling units. In the past most floor/ceiling assemblies using wood I-joists required one layer of 5/8" type 'x' gyp brd attached to rc channels attached to the wood I-joist, mainly to achieve a one-hour rating as I understand it. In researching many different wood I-joist manufacturer's testing reports, I can only find one similar to this. It is TJI's ICC ES PFC-4354, Assembly B. However is shows under its Assembly B on page 21 of this report that two layers of 5/8" type 'x' gyp brd are required over rc channel to achieve a minimum IIC=50.

Anyone out there know of a valid report with one layer of 5/8" type 'x' gyp brd attached to rc channel attached to wood I-joists that meets the 2003 IBC 1207 requirements?

IEEC 802.3.6 Vestibule

IEEC 802.3.6 Vestibules.

A door that separates conditioned space from the exterior shall be protected with an enclosed vestibule, with all doors opening into and out of the vestibule equipped with self-closing devices. Vestibules shall be designed so that in passing through the vestibule it is not necessary for the interior and exterior doors to open at the same time.

The Energy code and Com-Check requires a vestibule be provided in spaces over 3000 square feet on the main entry, how are you addressing this in your City or County ?
