no.....the building probably has one or more 2500 amp TPN three phase risers - there is tee at each floor split to serve the CLP/HKE meters, seems these are single phase meters in this case.
anyone can apply for more power by making application to CLP/HKE with load calculations (It has nothing to do with the building management) if the utility agree the tenant has to complete the installation and submit application for connection of the meter.
A new 3 three phase cable and containment from the existing meter room to the unit is likely to pass through the common area , it may fit inside the existing containment (existing trunking system) if not new containment will be needed and that needs approval from building owner/management, fire services dept. and perhaps even from BD.
the short answer is nobody knows
- does the meter room have space for new larger meter?
- does the busbar chamber have enough space for large capacity breakers?
- does the containment have spare capacity to house the new cables?
- is there enough space in the unit to dump the existing single phase board and fit a new three phase board?
pay an electrician day rate to check, it is not something that can be easily answered on a forum.
