National Building Code of India, 2016 by Bureau of Indian Standards SP 7-NBC

The National Building Code of India (NBC), a comprehensive building Code, is a national instrument providing guidelines
for regulating the building construction activities across the country. It serves as a Model Code for adoption by all
agencies involved in building construction works be they Public Works Departments, other government construction departments,
local bodies or private construction agencies. The Code mainly contains administrative regulations, development control rules
and general building requirements; fire safety requirements; stipulations regarding materials, structural design and
construction (including safety); building and plumbing services; approach to sustainability; and asset and facility management.

The Code was first published in 1970 at the instance of Planning Commission and then first revised in 1983. Thereafter three
major amendments were issued to the 1983 version, two in 1987 and the third in 1997. The second revision of the Code
was in 2005, to which two amendments were issued in 2015.

Due to large scale changes in the building construction activities, such as change in nature of occupancies with prevalence
of high rises and mixed occupancies, greater dependence and complicated nature of building services, development of new/innovative
construction materials and technologies, greater need for preservation of environment and recognition of need for planned management
of existing buildings and built environment, there has been a paradigm shift in building construction scenario. Considering these,
a Project for comprehensive revision of the Code was taken up under the aegis of the National Building Code Sectional Committee,
CED 46 of BIS and its 22 expert Panels; involving around 1 000 experts. As a culmination of the Project, the revised
Code has been brought out in 2016 as National Building Code of India 2016 reflecting the state-of-the-art and contemporary applicable international practices.

The comprehensive NBC 2016 contains 12 Parts some of which are further divided into Sections totalling 33 chapters (see
Annex 1).
The salient features of the revised NBC (see Annex 2) include, apart from other changes made, the changes specially in regard
to further enhancing our response to meet the challenges posed by natural calamities. The major changes incorporated in this
third revision of the Code are as follows:

a) Provisions for association of need based professionals and agencies have been updated to ensure proper discharge of responsibilities for accomplishment of building project.

b) With a view to ensuring ease of doing business in built environment sector, a detailed provision for streamlining the approval process in respect of different agencies has been incorporated in the form of an integrated approval process through single window approach for enabling expeditious approval process, avoiding separate clearances from various authorities.

c) Further, with a view to meeting the above objective, the provision on
computerization of approval process has been detailed, enabling online submission of plans, drawings and other details, and sanction thereof, aiding in speedier approval process.

d) The mechanism of ensuring certification of structural safety of buildings by the competent professional and peer review of design of buildings, have been further strengthened.

e) Requirements for accessibility in buildings and built environment for persons with disabilities and the elderly have been thoroughly revised and updated.

f) Provisions on fire and life safety have been thoroughly revised to meet the challenges of modern complex building types including the high rises.

g) Latest structural loading and design and construction codes including those relating to wind load,
earthquake resistant design of buildings, steel design and foundations have been incorporated with a view to ensuring structural safety of buildings including against a disaster.

h) Provisions relating to all building and plumbing services have been updated keeping also in view the latest international practices as related to the country.

j) Provisions have been updated to ensure utilization of number of
new/alternative building materials and technologies to provide for innovation in the field of building construction.

k) Construction management guidelines have been incorporated to aid in timely completion of building projects with desired quality in a safe manner within the budgeted cost.

m) Guidance has been provided for making buildings and built environment energy efficient and environmentally compatible, through the newly introduced and updated chapter on sustainability, namely Part 11 ‘Approach to Sustainability’

n) New chapters have been added on structural use of glass; escalators and moving walks; information and communication enabled installations; solid waste management; and asset and facility management.

The Code has been published in two volumes containing all the Parts and Sections.

The publication is available from Sales Counter at BIS Headquarters as well as various Regional and Branch Offices of BIS.
