Electromechanical works assembly and Supervision

Eathisa, through its development, has executed multiple works corresponding to complex mechanical assemblies, major electric works, automation systems and hydraulic equipment installation.

Our philosophy has been of establishing a symbiosis with big constructing companies in which Eathisa takes charge of the implementation of the works that, by their volume inside the global project, represent a minimal total cost, but that involve a high degree of problems since they are complex and required specialized personnel.
In this way, the constructing company delegates this part of the Project, on a trusted external unit and dedicates itself mainly to the civil works which, because of their volume, represent the biggest part of the cost of the contract.
