Are monolithic slabs on grade required?
NO, Appendix “E” section. AE502 of the RCNYS requires foundation systems to be frost protected (which means a standard pier and footing system), at or below the frost line. The exception states when a foundation system is designed to be otherwise protected from the effects of frost, such foundation system is not required to extend below the frost line. The key word “designed” means designed by an Architect or Engineer licensed to practice in NYS. Any systems that deviate from the standard pier and footing system are to be designed by an Architect or Engineer.
