Short Form Specifications for Field Testing Fenestration Products
Did you know that AAMA 502 “Voluntary Specification for Field Testing of Newly Installed Fenestration Products” and AAMA 503 “Voluntary Specification for Field Testing of Newly Installed Storefronts, Curtain Walls and Sloped Glazing Systems” both offer standard “Short Form Specification” language for use by specifying professionals?
Laboratory Evaluation of Expansive Soil
Clay soil that expands beneath a structure after construction can cause upward heaving of slabs and footings, resulting in buckling of foundation walls due to excessive lateral forces on the walls. Identification of expansive soil during the design phase of a project is important, so that mitigation measures may be implemented during construction to prevent future slab and foundation distress.
