Description / Abstract:
This code, when legally adopted as part of a general building
code, provides minimum requirements for design and construction of
residential concrete elements. In areas without a legally adopted
building code and lack of a project specification, this code
defines minimum acceptable standards of design and construction
practice.
This code supplements the general building code and governs
matters pertaining to design and construction of cast-in-place
concrete construction for one- and two-family dwellings and
multiple single-family dwellings (townhouses), and their accessory
structures, except wherever this code conflicts with requirements
in the legally adopted general building code.
Where this code conflicts with requirements contained in other
standards referenced in this code, this code shall govern.
This code is limited to design and construction of concrete
footings, including thickened slab footings, wall footings, and
isolated footings; concrete basement or foundation walls
constructed with removable forms or with flat insulating concrete
forms; and concrete slabs-on-ground.
Where the scope of this code and the scope of ACI 318 coincide,
design in accordance with ACI 318 shall be permitted for all
buildings and structures, and all parts thereof, within the scope
of this code.
This code does not govern design and construction of insulating
concrete form walls with a waffle or screen configuration; precast
wall elements; above-grade concrete walls; deep foundation systems,
such as piles, drilled piers, or caissons; and elevated concrete
slabs.
This code does not govern the design and application of systems
for surface drainage, waterproofing, dampproofing, or the
ventilation of radon gases.
When a building or structure contains elements that exceed the
limits of this code or otherwise do not conform to this code, these
elements shall be designed in accordance with ACI 318.
Where permitted by the statutes of the jurisdiction where the
project is to be constructed, construction documents for residences
designed by the provisions of this code need not be prepared by a
licensed design professional. Where required by the statutes of the
jurisdiction where the project is to be constructed, a licensed
design professional shall prepare the construction documents for
residences.
This code is intended to state only minimum requirements
necessary to provide for public health and safety for the design of
residences that fall within the scope of the IRC-2012. The owner or
the licensed design professional may require the quality of
materials and construction to be higher than the minimum
requirements stated in the code.
All references to minimum and maximum dimensions or values in
the code refer to those dimensions or values as specified.
This code is not intended to define contractual responsibilities
between all the parties involved in a project, nor is it intended
to settle disputes regarding contractual responsibilities.
The commentary text, tables, figures, or illustrations shall not
be used to interpret the code in a way that conflicts with the
plain meaning of the code text, or to create ambiguity within the
code that would not otherwise exist.
The English version in U.S. customary units is the official
version of the code. In case of conflict between the official
version and versions with SI units or in different languages, the
official version governs.
