The main subjects offered are basic and detailed engineering and technical advisory. The Electromechanical engineering work include making calculation for dimensioning and design of facilities. These facilities might be for Transmission and Distribution purposes, such as Power Substations and Transmission Lines, but also for residential and industrial systems. The electrical engineering work is focused on renewable energy facilities, from Photovoltaic power plants to residential and industrial systems. In case of designing a renewable energy power plant, the works may include the facilities required for the interconnection to the grid, such as Power Substations and Transmission Lines. The delivered documents result of the work depend on the project needs. The main kind of documents brought as a result of the engineering are: - Single line diagrams - Layouts - Calculation Memories - Equipment specifications - Bill of quantities/materials For the development of the project, it is required initial information that may depend on the project needs, but it may include: - Site location of the project - General Layout - Information about the current installed system - Information about the considered equipment to be installed - Technical restrictions that have to be considered to the design development Technical advisory is about giving a guide throughout all the project development at all its stages. This orientation may depend on the project nature and be focused on: - Equipment selection - Equipment positioning and spacing - Technical reviewing of engineering documents There might be other subjects in which services can be offered if the nature of the project similar to those exposed in this section.
