Excuse me, what kind of project needs a second-class electromechanical builder?

Mechanical and electrical professional builders need in the following industries: mechanical and electrical installation engineering companies, electric power construction companies, and construction companies involved in plumbing installation. Companies that simply build houses are not needed in construction companies called civil engineering or infrastructure companies. Enterprises with civil engineering qualifications only need the certificate of construction engineering (building houses does not require electromechanical majors).
