Electrical engineers further develop the conceptual designs into spatially and technically coordinated layouts. Their responsibilities in the DD phase include:
- Finalizing lighting layouts, fixture types, circuit distribution, and emergency lighting provisions
- Developing socket layouts, small power distribution, and control strategies
- Preparing single-line diagrams (SLDs) for DBs, SMDBs, MDBs, and MV connections
- Performing detailed load calculations, voltage drop analysis, and feeder sizing
- Coordinating electrical panel locations, conduit routes, ceiling voids, and ELV system requirements
Electrical output ensures that the power infrastructure supports all disciplines and functional spaces while complying with applicable standards and performance criteria.
