Any calculation, commercial offer, engineering calculation of a system begins with a project. Even if in the first minutes, hours it is only a sketch - the arrangement of equipment on the plan, cable routes, selection of equipment by characteristics, coordination, consideration of price, availability, options, requirements of Departmental Building Regulations, State Building Regulations, State Standards of Ukraine, Sanitary Norms and Rules, technical specifications, if provided by the Customer.
A full-fledged project meets the requirements of the Unified System of Design Documentation, the necessary sections in the explanatory note are added, and the cost estimate documentation is drawn up.
It is better not to save on the project. In some cases, it is mandatory. For example, a fire alarm system project, or a project for a government organization, or a project of engineering systems for a large facility under construction. But we will not ask you for money for a small sketch, plans, diagrams.
