Building codes

Building codes are the set of norms that contain all the standards for the construction of all the building and non-building structures. It is essential to follow the guidelines given in the building codes to get the project approved by the local authorities. The engineers, architects, contractors, and all the people involved in construction activities are obligated to refer to the building codes before performing any construction activity. In the United States of America (USA), The I-Codes, which are the International Building Code (IBC) or International Residential Code (IRC), electrical codes, plumbing codes, and mechanical codes are the model codes adopted. These model codes are updated after every three years.
