6.2.1 Concept Design Phase
Electrical consultants are responsible for defining the overall power strategy and system framework. Their scope includes:
- Estimating total connected and demand electrical loads
- Identifying preliminary locations and size requirements for MDBs, SMDBs, and electrical rooms
- Proposing MV supply options and standby power strategies (generator, UPS)
- Outlining lighting philosophy and emergency lighting requirements
- Defining initial ELV system zones (data, security, fire alarm) and room allocations
Electrical concept design ensures early coordination of critical infrastructure and allows space for electrical equipment in the architectural and structural layout.
