 In June 1946, Manuel António da Mota incorporated Mota & Compania in the Portuguese city of Amarante. In that same month and year a branch of the company was opened in Angola. Until 1974 Mota & Companhia operations focused on the Angolan territory, firstly in the exploration and processing of timber and as of 1948 also in the area of construction and public works. In 1952, Mota & Companhia was awarded the implementation of Luanda International Airport, near Luanda, the first major public work executed by the company in this territory, at the time still under Portuguese colonial administration.
In the same year and in Lisbon, Portugal, Fernando José Saraiva and António Lopes de Almeida founded Engil, Sociedade de Engenharia Civil, Lda. In 1954, Simões Cúcio and António Valadas Fernandes joined Engil and gave it a new boost and renewed energy.
In 1961, Engil's operations until then focused on the region of Lisbon start spreading to other regions within the Portuguese territory through the award of the Escola Industrial e Comercial of Castelo Branco, Portugal, and the construction, in Mirandela, of the Bridge over the Tua River. 1969 will be remembered for the signing of a contract with the company Siemens-Baunnion. Engil acquires in exclusive for Portugal the rights of use of the Siemcrete patented sliding forms system, allowing it to carry out countless major works as from then, involving silos and chimneys. Under the expansion of its operations the North delegation was created in Porto.
 In 1975, Mota & Companhia expanded its activity to other African territories and started in Namibia with the construction of the Dreihuk dam. In South Africa, it was responsible for the infrastructures of the Sun City Resort and of the Matooster – Bierkraal road. Later, in Swaziland the company built the Lonhlupheko – Lomahasha road. All these constructions led Mota & Companhia into a process of progressive internationalization of its operations and businesses.
 1976 was marked by an upturn of Mota & Companhia in Portugal through the award of a small dam (Lucefecit, Alentejo). Shortly afterwards, Mota & Companhia was awarded the contract for the regularization works of the Lower Mondego River. This allowed the company to launch itself as one of the top construction companies for large national building projects and soon became the third largest Portuguese company within this sector.
 In 1978, together with Retosa, with head office in Caracas, Venezuela, Engil participated for two years in the construction of factories and of the Guri Dam. As of 1980, Mota & Companhia expanded its operations within the People's Republic of Angola. In this same year and in a partnership with the Angolan government, it set up the company Construção de Terraplenagens Paviterra, UEM. Mota & Companhia and Paviterra were for many years the only corporate structures involved in the construction of public works in Angola.
 In August 1987, Mota & Companhia, a limited company, became a public limited liability company, following which it floated 12% of its equity capital on the stock market and requested admission to the Lisbon Stock Exchange. That year Engil SGPS was incorporated endeavoring to meet the evolving public and private works market and the need to diversify its activities. In the following years the company acquired these companies: Sociedade de Empreitadas Adriano (1988), Gerco - Sociedade de Engenharia Electrotécnica, SA (1990) and Ferrovias e Construções (1991). The year 1987 became associated with the major public work - the construction of the Lindoso Dam. The size and technical features of this construction work make of it a landmark amongst the major works developed by Engil.
 By entering the Angolan market in 1989 Engil's internationalization process is once again relaunched. In 1993, 1994 and 1996, a new boost was given to the internationalization process when the company entered, respectively, the following markets: Mozambique, Germany and Peru.

 In 1994 Mota & Companhia comprised the construction consortium of the Vasco da Gama Bridge, in Lisbon connecting north and south banks of the Tagus River. The year is further marked by more diversification of businesses by venturing into the area of Transport Concessions together with other reference companies.
