Until the 1988 (2045 BS) Udayapur Earthquake in Nepal, we did not have any regulation or good practice document in place to guide earthquake safe construction in the country, although the disaster pointed us in the right direction. Under the Ministry of Physical Planning and Works (MPPW), the Department of Urban Development and Building Construction (DUDBC) developed the Nepal National Building Code (NBC) in 1993. The United Nations Development Programme (UNDP), the United Nations Centre for Human Settlement (UNCHS) and few domestic as well as foreign subcontractors’ teams provided their technical assistance in developing the NBC. 

The NBC implementation went into effect after the authorization provided by the Building Construction System Improvement Committee (established by the Building Act 1998). Following a government notice in the Nepal Gazette in 2006, the NBC implementation became mandatory in all the municipalities in Nepal.

Under the safety section of the requirements, the NBC included Construction Safety (NBC 114: 1994) standard and provisional recommendation on Fire Safety (NBC 107: 1994) standard. NBC 114 standard covers provisions for Health & Safety of workers in building construction/demolition works being performed under a formal contract between the employer and the contractor. In the case of owner-built construction sites the requirements are advisory. Similarly, NBC 107 provides fundamental requirements for Fire Safety in commercial, official or ordinary residential buildings.

NBC 114: 1994

Given below are the provisions for the maintenance of Construction Safety control measures and their corresponding safety requirements as per NBC 114.
