Documentation for Building Permit (DSP):

This stage represents the project documentation required to obtain a building permit.
It defines the key parameters and principles of the future construction – location, capacity, technology, safety, environmental impact, and compliance with legislation.
DSP does not contain detailed installation drawings but presents the overall technical and architectural design.

Typical parts of DSP:

• Technical report
• Site layout drawing (location plan)
• Single-line connection diagram
• Description of connection to the distribution network
• Fire safety solution (PBŘ)
• Statements from relevant authorities and coordination with public offices

Construction Documentation (DPS):

This stage is intended for the implementation and installation of the construction.
It is developed based on the approved DSP documentation and includes detailed drawings, diagrams, and calculations used by contractors, installation companies, and technical supervisors.
DPS precisely defines the types of cables, protections, equipment, structures, and installation methods — down to the labeling of individual circuits.

Typical parts of DPS:

• Detailed technical report
• Wiring and cable connection drawings
• Switchboard diagrams (DC/AC sections, string layout)
• Grounding, surge protection, and lightning protection details
• Layout drawings of panels, structures, and cable routes
• List of components, bills of materials, and circuit labeling
• Fire safety report and calculations
• Coordination of disciplines (electrical, structural, and civil parts)

As-Built Documentation (DSPS):

This stage is prepared after the completion of construction and records the actual state of execution, including all modifications made during the implementation.
DSPS is essential for the handover of the project to the investor, for inspections, and for subsequent maintenance. It reflects the real condition of the installation and serves as the official technical archive of the facility.

Typical parts of DSPS:

• Updated drawings according to the actual execution
• Inspection and measurement reports
• List of materials and components used
• Photo documentation of the installation
• Records of changes made during construction
• Declaration of conformity with the project and legislation
• Operation and maintenance documentation (manuals, certificates)
