digging up roads utilities

.

why the government cannot make the water, electric, gas, sewers etc all put these in at the same time and dig up the road only once. This nust save cost and time  

Why does this idea matter?

They are builing a new development near my parent house this has  been going on for 6 months and the road has been dug up ats least10 times the same hole in the same place the unnecessary upheavels this causes to resident traffic etc is unmeasurable

and the cost to dig up the same hole over and over again can commer sence prevail one hole for one week one day each
