Its main offices were initially located in the city of Arequipa, but due to the growth of the company, and in order to satisfy the needs of all of its associated companies, it moved its operations to the city of Lima. For years, REA has grown considerably, serving different clients in the energy, mining, industrial, and projects sectors at the national level.
