The Botswana Institution of Engineers (BIE), is a professional institution consisting of engineers from all engineering disciplines. It was formed in 1983 by a group of engineers concerned about the development, practice and status of engineering in the country, particularly with regard to the importance of its contribution in national development.

It was previously known as the Botswana Engineers Society but was changed in 1995 to Botswana Institution of Engineers, following a major review of its constitution. The BIE is a rapidly growing institution and has great potential. One of the greatest achievements of the institution has been the Engineers Registration Act (ERA) enacted by the parliament by parliament. In December 2008, the amended ERA was approved by Parliament – a move that would ensure full regulation of the engineering profession and require every practicing Engineer in Botswana to register with BIE. The Registration Act would be implemented by the Engineers Registration Board (ERB) which will initially be funded by The Botswana Government, until such time that both BIE and ERB are self-sustaining.

The administrative and operational structures of ERB are being established with the support of the Ministry of Works and Transport. At long last, the long-awaited era of engineering regulation has arrived, and the BIE urges all engineers to immediately register with the BIE.

The institution has established a Memorandum of Understanding with the UK Institution of Civil Engineers. It is also a member of the Commonwealth Engineers' Council and the Botswana National Construction Industry Council. The institution also maintains close collaboration with a number of institutions or organizations involved in engineering in Botswana.

These include the University of Botswana, Association of Consulting Engineers, Botswana Technology Centre and the Association of Building Contractors. The institution continues to seek relations with other international institutions. There has been communication with the Zimbabwe Institution of Engineers for an agreement. This is still under consideration.
