Design
Design documentation for electrical equipment, from a socket in a family house to an outdoor 110 kV switchyard. One designer across the whole range, so nobody has to hand the transition between voltage levels to three different firms.
Electrical installations
Family and apartment buildings, offices, retail, production halls, warehouses, agricultural buildings, data centres, outdoor areas, street lighting, EV chargers and standby supplies.
Service connections and metering points
Underground and overhead connections, connection cabinets, meter boards and main feeders. From the connection application to the installed meter.
Substations
Packaged, pole-mounted and built-in. Distribution, customer, industrial and multi-transformer.
Lines and networks
Underground and overhead lines at low and high voltage. Public distribution networks, site networks, sectionalising cabinets and boards.
Switchyards and transformer stations
Switchyards and switching stations at 22 kV, outdoor air-insulated 110 kV switchyards and 110/22 kV transformer stations.
Solar and battery storage
Roof, facade and ground-mounted plants and battery storage. Local source or licensed generator, including protection, fire disconnection and yield calculation.
Lightning and surge protection
Air termination, down conductors, earthing, separation distance and coordination of surge protective devices. The protection level follows risk management.
We do not design 110 kV lines and above, whether underground or overhead. Switchyards and transformer stations at that level we do.
Stages of documentation
Under Section 9 of Act No. 25/2025 Coll. (the Building Act), in force since 1 April 2025. It replaced Act No. 50/1976 Coll.
- Building intent formerly DÚR
- Building design formerly DSP
- Design for notification simple structures
- Detailed design formerly DRS
As-built documentation, formerly DSPS, falls under Section 10 (4) of the same act into construction documentation. Operating documentation is covered by Section 11, and approval for use by Sections 66 and 67.
How it works
Brief
The stage of documentation, the voltage level and what the installation has to do.
Inputs
Site plan, survey, required capacity and the operator opinion if it has been issued.
Calculations
Sizing, protection, short circuit, voltage drop and earthing.
Documentation
Drawings, technical report, external influences protocol and bill of quantities.
Consultation
Comments from authorities and network operators are worked into the documentation.
