I'd have told the electricians to run a new conduit.  Obviously, the one
they installed was either to small, had too many bends or both.  There are
limitations on allowable pulling force due to the tendency of the conductors
to stretch, effectively reducing the diameter of the conductors and with it
their ampacity.  If there had been any coaxial cables for addressable loops
in the bundle using such force could render the system inop.

Not saying you did something bad, Flash, but I'd have declined to finish
until they provided a proper conduit with properly spaced pulling locations.
