The Nepal National Building Code (NBC) sets the mandatory technical standards for building design and construction across Nepal. First developed after the 1988 Udayapur earthquake and revised over the years, the NBC covers seismic safety, structural design, materials, and construction practices. This hub brings together practical, engineer-friendly summaries of the key NBC provisions — from NBC 105 seismic design and NBC 202 mandatory rules of thumb to material codes, drawing guidelines, and quick-reference checklists for the design office and site.
