That makes perfect sense, but locating the utilities/depth first by hand 
digging otherwise the risk of damaging them with a rogue borer is high.
The idea behind the old BS5837 and radial trenching towards the tree to avoid 
significant damage shouldn’t apply to highway trees however due to rpa offset.

It all depends upon existing service runs and any other u/g infrastructure. 
Thrust-boring is good provided that the location and depth of u/g "things" is 
known and/or investigated. It is not cheap but often cheaper and less 
complicated than manual digging. Basically a mini-digger hole at each end. 
The last one we did (about 3 years ago) was for a 40-metre water pipe run and 
he was finished entirely by 3.30.
