Teixeira Duarte is the identity of a business Group that presents itself through its brand image: a Portuguese Group originally founded as an engineering company. Its engineering roots came from its founder who, with an entrepreneurial spirit and with support from its human resources and technical equipment, several decades ago expanded the company's activities to other sectors and markets, with a marked identity upheld by all involved over one hundred years of business.

The Engineer Ricardo Esquível Teixeira Duarte started the Teixeira Duarte Group’s business in 1921. The company, now called “Teixeira Duarte - Engenharia e Construções, S.A.”, was also incorporated by him in 1934 before later taking on the role of the Group’s parent entity in 2010. It opened up its capital to employees and became a limited liability company in 1987, and was listed on what was then the Lisbon Stock Exchange in 1998.

In 2010, “Teixeira Duarte, S.A.", incorporated in 2009, acquired all of the share capital of "Teixeira Duarte - Engenharia e Construções, S.A.” under the scope of a Public Exchange Offer, and became the listed company at the head of the Teixeira Duarte Group, which today consists of a group of entities that lie within its consolidation perimeter.
