When estimating structural quantities in embodiedcarbon.tool, cove.tool uses commonly accepted standards for member sizing. The tool provides a conservative estimate of structural material by providing approximate sizes for the typical worst-case member, and assuming all like-type members are similar. You can read more about the methods here.
When estimating structural quantities, cove.tool uses validated industry standards and engineering best practices, adhering to the guidelines laid out in the following standards:
ACI 318-19, Building Code Requirements for Structural Concrete and Commentary is used in the estimation of concrete structural members, including substructure and foundation elements.
ANSI/AISC 360-16, Specification for Structural Steel Buildings is used in the estimation of structural steel elements, primarily beams, girders, and columns.
SJI 100-2020, Load Tables and Weight Tables for Steel Joists and Joist Girders has been used to select reasonable configurations for estimating material quantities in open-web steel joists.
2018 NDS, 2018 National Design Specification (NDS) for Wood Construction is used to inform estimates for mass timber elements, including glued laminated timber (glulam) frames and cross-laminated timber (CLT) elements.
IBC 2018, 2018 International Building Code is used for live load conditions and other general requirements.
ANSI/SDI C-2017, Standard for Composite Steel Floor Deck-Slabs is used for estimating quantities for composite steel floor deck elements.
SDI FDDM2, Floor Deck Design Manual, 2nd Ed. is used for estimating and industry standards in floor deck design.
SDI RDDM2, Roof Deck Design Manual, 2nd Ed. is used for estimating and industry standards in floor deck design.
