Schematic elevation drawn by GANI to locate the scope — not an architectural document.
In a tower, the electrical infrastructure is a production line turned on its side: the same panel repeats floor after floor, the riser feeds it, and the construction programme decides when each floor is ready. Except nothing repeats exactly — the building tapers, so floor areas, loads and tenant splits change as you go up, and every variant still has to be documented, tested and delivered in the week it is needed.
STARTING CONDITIONA distribution concept and load schedule per floor band existed. Panel standardization, manufacture and the delivery rhythm did not.
- Distribution concept and load schedule per floor band
- French installation requirements and the client technical specification
- Tenant metering and sub-billing requirements
- Riser and shaft coordination drawings
- Floor-by-floor construction programme with delivery dates
- Panel standardization: one concept, a controlled set of floor variants
- Detailed design and parts lists per variant, revision-controlled
- Series manufacture to IEC 61439 with French installation requirements applied
- Routine test per panel, records archived to the serial number
- Energy metering and control integration to the building management system
- Delivery released floor by floor against the construction programme
What the program delivers.
- Floor panels delivered to the programme rather than to a warehouse
- One documented concept instead of dozens of one-off boards
- Metering per tenant available from the first occupied floors
- Late floor changes absorbed as controlled variants, not redesigns
What the infrastructure actually controls.
- 01Floor distribution boards with per-tenant sub-metering
- 02Riser distribution and changeover monitoring
- 03Lighting and blind control interfaces per floor
- 04HVAC terminal unit control interfaces
- 05Plant-level interfaces to chillers and air handling
- 06Energy data to the building management system
