Is there any particular two inch trenches were dug? Was it too expensive? Extra permits?

- teachrdan 8y agoIf I understand your question correctly, they used 2" trenches because shallower === faster. However, they were so shallow--and the surfacing material so brittle--that the fibers ended up getting damaged too often. So they corrected with slightly deeper trenches afterwards.
- vb6lives 8y agoShallower === cheaper
- MrEldritch 8y agoFaster also === cheaper, so "shallower === faster" implies "shallower === cheaper" anyway.
- Someone1234 8y agoThey were copying a Germen technique (curb trenching) but trying to cut costs even further[0]. Google called it an experiment. [0] https://www.youtube.com/watch?v=Wisrs03EkDM https://www.youtube.com/watch?v=Wisrs03EkDM
