What is NBR 6122?
NBR 6122 is the acronym for Norma Brasileira (Brazilian Standard) Projeto e execução de fundações (Design and construction of foundations). It is a technical document that establishes the rules and guidelines for the planning, execution, and control of foundation works in Brazil.
NBR 6122 was first published in 1960 by the Associação Brasileira de Normas Técnicas (ABNT), which is the national body responsible for standardization in Brazil. Since then, it has been revised several times to incorporate new technologies, methods, and knowledge in the field of geotechnical engineering. The current version, NBR 6122:2019, was published on September 30, 2019, and replaced the previous version, NBR 6122:2010.
Why is NBR 6122 important?
NBR 6122 is important because it provides a common framework and language for the design and construction of foundations in Brazil. It helps to ensure the quality, safety, durability, and efficiency of foundation works, as well as to prevent failures, damages, and disputes.
NBR 6122 is also important because it reflects the state-of-the-art knowledge and best practices in geotechnical engineering. It incorporates the latest research findings, technical innovations, and international standards in the field. It also addresses the specific characteristics and challenges of the Brazilian soil conditions, such as expansive, collapsible, residual, or tropical soils.

Moreover, NBR 6122 is important because it is mandatory for all foundation projects in Brazil. It is a legal requirement that must be followed by engineers, contractors, consultants, owners, public authorities, and other stakeholders involved in foundation works. Failure to comply with NBR 6122 can result in legal sanctions, penalties, or liabilities.
How to download NBR 6122 PDF 2019?
If you want to download NBR 6122 PDF 2019, you have two main options: you can either buy it from the official ABNT website or you can search for free or cheaper alternatives online.
The official ABNT website offers the option to buy NBR 6122 PDF 2019 for R$285.00 (about US$54.00). This option guarantees that you will get the original and updated version of the standard, as well as access to other ABNT services and benefits. However, this option may be too expensive or inconvenient for some users who only need the standard for a specific purpose or a limited time.
The alternative option is to look for free or cheaper sources of NBR 6122 PDF 2019 online.
