How we build

Done right below grade.

Most of what we build gets buried. That is exactly why it has to be right the first time.

Typical utility trenchStep 1 of 5
01

Locate & excavate

Utilities located and the trench opened to design depth, with spoil managed so the site stays clean and safe.

02

Shore & bed

Shoring set where the depth calls for it, then bedding placed and graded so the pipe sits exactly where the drawings say.

03

Lay & test

Pipe and manholes installed to line and grade, then tested and documented for closeout.

04

Backfill & compact

Backfilled in lifts and compacted, so nothing settles after we leave.

05

Restore

Surface restored and the site handed back ready for the next trade.
