Greetings in this tumultuous times,

Since all upcoming seminars are cancelled, I have created “Saum’s Pod Cast Series” of all lectures.

  • Plumbing,
  • Energy Codes (Title-24),
  • Mechanical, and all
  • 6 Architectural Registration Exams V 5.
  • In addition, Covid 19 impact on the building design is inevitable. Multiple sessions will be devoted to Covid 19 impact.
  • My 5 hours seminar on “Construction and Law” will follow the trails of Pod Casts.

The plumbing Code changes are more than presented here. These are major code changes. Please note all code books are available for viewing online for free.

Other tabulations are generated by other Jurisdictions. I will copy them at end of this tabulation. However, they will not be on “Saum’s Pod Cast Series”.

Hyperlink of downloading the “Saum’s Plumbing Code Changes Pod Cast Series” are to follow this article.
