6.2.2 Schematic Design Phase
Electrical engineers focus on system concept development, space allocation, and infrastructure planning during schematic design. Their responsibilities include:
- Estimating electrical loads and confirming preliminary panel sizing and locations
- Planning riser routes, electrical rooms, and DB/SMDB/MDB positions
- Defining the lighting concept, emergency lighting provisions, and power zoning
- Identifying requirements for ELV systems (CCTV, data, access control, etc.)
- Allocating space for UPS, generator, transformer, and MV equipment
The schematic design phase for electrical ensures that spatial and functional provisions are incorporated early, avoiding costly relocations in later stages.
