Not yet, but there will be a nylon pull cord available, which can be used once the conduit has been cut in the correct place, which we don't yet know - it will depend on the engineer.
So long as the drop wire fits in the conduit (8mm ID smooth wall) it should be possible to pull it down the soffit, through the conduit and back out at ground level. Then pull the internal run through from where the ONT is to be located.
There are currently various unknown, the engineer may fit an internal CSP, so any holes will be drilled on the day, and the conduit cut in the correct location. If the conduit is not suitable for the drop wire to run through, then it will just run externally.
