Nepal National Building Code:
 A building code is a set of rules that specify the
minimum acceptable level of safety for constructed
objects such as building and non-building structures.
 The main purpose of building codes is to protect public
health, safety and general welfare as they relate to the
construction and occupancy of buildings and structures.
 The building code becomes law of a particular
jurisdiction when formally enacted by the appropriate
authority.

Necessity of Building Code
 In the context of Nepal, more than 95% of residential
buildings in Nepal are constructed in absence of
Technical Supervision by Technical Professional by the
House-owner himself.
 Instead of locally available material, use of new
construction technologies and materials in growing
 At local level to the masons and the house-owner, there
is no proper knowledge about new construction
materials and technology
 In general, the housing construction quality is degrading
with time.

Formulation of Building Code:
Brahma Shamser J.B.R in his book ““!(();fnsf]dxfe"sDk” explained the
following:
 What were the effects of Earthquake? How rescue, relief and
rehabilitation was done?
 What are the Causes of Earthquake and If there is Possibility of
anther Great Earthquake in Nepal?
 What are the measures that need to be taken to minimize the effect
of Earthquake?
 What need to be considered while constructing a new house?
 How can we make cement using locally available materials at
local level?
However, then government as well as local people didn’t gave much
interest about this.

Start of Building Code Formulation:
After 2045 Bhadra 5 Earthquake:
 Resettlement and Reconstruction Project on Earthquake
Affected Area was implemented
 Earthquake Reconstruction Project suggested to develop
“Housing Policy” in Nepal
 “First Housing Survey” was completed in 2048/049 BS in
Nepal
 From the housing survey, importance of Building Code was
prioritize in Nepal
 “Nepal National Building Code formation plan” started from
2050/51 by then Ministry of Housing and Physical Planning
under the financial assistance of UNDP/UNCHS(Habitat)
 “Nepal National Building Code” was prepared in 2052 BS

Experts involved in Building Code Formation
Experts involved in Formation of Building Code were from:
 Technical Persons from Then “Building
Department”(Now: Department of Urban Development
and Building Construction)
 International Technical Consultants:
• Beca Worly International Consultants Ltd, New Zealand
• Golder Associate Ltd. , Canada
• Urban regional Research, USA
 Nepalsese Consultants:
• Silt Consult(P) Ltd.
• TAEC Consult(P) Ltd.

Formulation of National Nepal Building Code
First edition of building code had 20 codes and in
2060 BS three codes (Architectural, Sanitary and
Electrical) were added and all codes were approved
by Cabinet of Minister in 2060 BS.
Building code was implemented after it was approved
by Cabinet of Minister, in then 58 Municipality, 28
District Head Quarter which were VDCs and 76
emerging towns which were VDCs.

204 Masonry Structure Built using Mud
205 RC Building without Masonry Infill
206 Architectural Provision
207 Electrical Configurations in Structure
208 Water Supply and Sanitary Provision in
Building

Nepal National Building Code has been divided into 4
Volumes for its better implementation:
1. International State-of-Art
2. Professionally Engineered Building
3. Mandatory Rules-of-Thumb
4. Guidelines for Remote Rural Buildings-Low
Strengths Masonry/Earthen Building

A. International State-of-Art
 Complex Buildings can be designed and constructed
based on Foreign Codes
 NBC 000: International State-of-Art

B. Professionally Engineered Building
 Building designed by Technical Persons(Engineer or
Architects) having plinth area more than 1000 sq. ft
and more than 3 storied, structural span more than
4.5 m.
 NBC 101-114,
 NBC 206-208

C. Mandatory Rule of Thumb
 Building that can be designed by mid level technical
professional with plinth area less than 1000 sq ft and
less than 3 storied building, structural span less than
4.5 m.
 NBC 201-202
 NBC 205

D. Guideline for Rural Building
 Dwellings up to 2 storied in place where it is not
possible for regular supervision of Technical
Professionals
 NBC 203 and NBC 204

Strategy for Building Code Implementation:
 Make new construction safe in disasters based on
building code compliance
 Retrofit of Existing Structure based on codal
provision to make it safe in disasters.
Process:
Requirement for Building Code Implementation:
 Policy Development, Capacity Development at Local Level,
Awareness Campaign, Development of National Level Program
for Building Code Implementation

Objectives:
At the end of the session, participants will:
 Know about Building Code
 Be able to describe the need of Building Code
 Be able to describe the formulation of Building
Code
 Be able to describe the implementation strategy of
Building Code in Nepal
