MASCO General Contracting was founded in 1968 by Mohammed Ali Alswailem. He had started his career in the early 1950s as an employee in the Arab American Oil Company (Aramco), which sharpened his talent and vision to establish, in the mid-1960s, his sole partnership corporation, which was solely in road construction.
Mohammed Al Ali Al Swailem Trading & Contracting Co. was established as a Saudi limited liability company in 1984 with a capital of SR 3 million.
In 2006, the company increased its capital from SR 3 million to SR 100 million. The company was converted into a closed shareholding company in 2007.
