Why the National Building Code (NBC) is required in Nepal?

After the 2045 B.S earthquake that time his government felt that they require their own Building Code. More reasons are:

  1. Due to the lack of country code mostly engineers are forced to use other country building codes.
  2. Without considering the strength of materials people are constructing residential buildings.
  3. 10-15 years ago, about 95% of the building’s structures are built-up without taking the suggestion of any technicians or engineers.
  4. Even technicians do not have proper knowledge and idea about earthquake residential buildings.

Implementation of NBC Codes

From 2060/04/12, NBC is started to use in government and government shared construction buildings. Later in 2062/11/01 after the publish of Gadget NBC is implemented in 58 municipalities, 28 VDC where district headquarter lies at that time.

2. Professionally Engineered Buildings (PEB):

Buildings having a plinth area of more than 1000 square feet or a structural span greater than 4.5-meter are categorized in Professionally Engineered Buildings (PEB). These buildings should be designed and built-in with guidelines of engineers.

3. Mandatory Rule of Thumb (MRT)

The main objective of these Mandatory Rules of Thumb (MRT) is to provide ready-to-use dimensions and details for various structural and non-structural elements for up to three-storey reinforced concrete (RC), framed, ordinary residential buildings commonly being built by owner-builders in Nepal. Their purpose is to replace the non-engineered construction presently adopted with pre-engineered construction. Now, it is mandatory to follow MRT while designing or constructing buildings in every municipality of Nepal.

4. Guidelines for Remote Rural Buildings (GRB)

Guidelines for Remote Rural Buildings (GRB) guidelines are prepared in order to raise the seismic safety of low-strength masonry buildings and earthen buildings. These guidelines are intended to be implemented by the owner/builder with some assistance from the technicians.
