Engineer installing fibre in ducting
I recently purchased an older home with solid brick walls and a cavity (with insulation of some kind), and want the ONT in a specific place in the house.
My plan was to drill a hole through the walls and come into the house under the floor (the house is raised compared to the ground outside), where I can then install a smooth bore pipe/duct myself from the external wall to where I want the ONT, with the pipe going through the crawl space under the house where an engineer clearly wouldn't enter and couldn't fit a fibre through there themselves anyway.
There are a few reasons why I want to do things my way: 1) I don't want the ONT or other network equipment in the living room or bedroom, I want it in the hall in the centre of the house; 2) it doesn't matter where the hole is drilled on the front wall, as the power sockets are not near external walls so the fibre or power cable would have to go 10ft+ to be near a power socket anyway; 3) the living room has a large and heavy cabinet in the only corner that a hole could be drilled in, as the radiator goes the rest of the way to the opposite wall under the living room window, and I have no means of moving it quickly; 4) I want to make the engineer's job as easy as possible while still having control of where I want everything.
Is this internal ducting something an Engineer will be happy to use? And if so, can someone give me an idea of what size of box they would install on the outside of the property, and where the hole would be within that box for the smaller fibre to come though so I can just have them fit the box over the hole and pipe? And also how large I would need to make the bend radius of the pipe to not exceed the bend radius of the fibre?
If an engineer wouldn't install fibre in the ducting, would they hook up to my own fibre if I installed it myself, and also put the ONT where I want it inside the house?
If I installed external ducting to hide the fibre underground and protect it from damage from plants and digging, would the engineer be able to use that or do they again have to manually dig a channel themselves to partially bury a fibre cable which is then easily damaged if I want to dig up that section of the garden later?
