Telus Fibre 1.5 installation

[wireless]

Okay finally Telus updated our area and I have installation appointment in 2 weeks. I have some question

1. How do I make the subcontractor install an underground "drop cable"? I already told the subcontractor, I prefer underground, instead of cutting a thin line in grass and burying the conduit under the grass.
2. The TV connection: Can they use existing coaxial cables inside the house? As my basement is developed, I really hate having another sets of cabe running inside my house

Thanks
