CESEL has developed most of the river ports in the Peruvian Amazon since the mid-1970s, when it designed and supervised the construction of the ports of Iquitos, Pucallpa and Yurimaguas. He has to his credit the design and construction supervision in 42 ports.

• Its participation in the main maritime ports of the Peruvian coast has also been very important, highlighting the expansion and modernization of the Port of Callao, the construction of a new container terminal in the southern zone and the modernization of the multipurpose northern terminal.

CESEL develops services for the oil industry, with regard to related facilities such as storage tanks, pipelines, oil pipelines, gas pipelines, batteries, pumping stations, treatment plants, etc.

• It has provided services to the La Pampilla and Talara refineries, among other important facilities. CESEL also develops services in the field of petrochemicals and refineries for the production of biofuels.

CESEL has developed in the field of Metros and Railways, being in charge of the Lima and Callao Metro Network in its line 1 – section 1 and 2, which goes from Villa El Salvador to San Juan de Lurigancho with an extension of 34 km. , as well as the Plaza Mayor station among its main representative projects.

• Line 1 of the Lima Metro is one of the most important social mega-projects that have been carried out in Peru, since it improves the quality of life of thousands of inhabitants of the city. Not only has the image of the capital been improved, but it now places it on a par with the big cities of other Latin American countries.
• Currently, Line 2 of the Lima Metro is underway with an extension of 23.7 km. CESEL is supervising the studies and civil works, electromechanical works, rolling stock, tests and commissioning of the same. Additionally, a complementary study of the Lima Metro network is being carried out (transportation demand, route plan, economic-financial analysis), and its determination in its first 5 lines, which add up to 144.4 km in length and 122 seasons.

CESEL develops services for the oil industry, with regard to related facilities such as storage tanks, pipelines, oil pipelines, gas pipelines, batteries, pumping stations, treatment plants, etc.

• Including all its specialized components such as surgical centers, obstetric and neonatology center, hospitalization, intensive care unit, diagnostic imaging units, radiotherapy, etc. Generating this a total of 5,366 beds and 616,335 m² of hospitals and medical complexes.

CESEL has vast experience in the important aeronautical sector, the demand for growth in passengers and goods makes it necessary to optimize services at airports in order to improve air transport management, Clients from the public and private sectors have technical support in our company since we have highly qualified professionals that we can define from consulting to commissioning, as well as security services on the airside of airports.
