Hi
I am acting as the electrical engineer for a project that is currently in RIBA Stage 5.
The design of said project was carried out by another M&E Consultant.
The project is essentially 5 x large commercial / retail units, a large car park and a communal area at the back for deliveries etc. All of the units are attached but are separate entities with their own incomer from the local substation.
The client has agreed with the tenant to provide lighting to all of the units which shall be maintained and paid for by the client (landlord).
The design currently proposes a circuit to be fed from the landlord supply in the communal area to supply the lighting on the units, with the cable for said circuit running behind the cladding of the retail units clipped to the steel structure using girder clips.
I have a few concerns with this and I don't think it is the correct way to do it.
However with this said I just wanted a second opinion before I raise the alarm so to speak.
Concerns:
1.) Cable is crossing multiple boundaries going from landlord area to tenant areas
2.) Tenants will be unaware of cable and even if they are will be unable to isolate it if they need to do some work that involves drilling through the cladding
3.) If a tenant was to isolate their unit at the incomer, they would still have a live cable running through their unit
4.) Maintenance access will require removal of the cladding on the retail unit
