About usAbout usWhat We Do
Underground services from locate to lifecycle
It starts with Subsurface Utility Engineering — four quality levels of certainty, applied where they change the decision.
QL-D
Records
Utility records and histories compiled into a baseline picture.
QL-C
Surface
Visible surface features surveyed and correlated with records.
QL-B
Designate
Geophysics — GPR and EM — marks horizontal position underground.
QL-A
Daylight
Hydro-vac test holes expose the utility for exact position and depth.
Dedicated Project Locates
Locate delays shouldn’t set your build schedule.
- Dedicated Project Locates — locators assigned to large regional FTTH installations, working with contractor crews on an ongoing basis.
- Ultra Urgent Locates — turnaround capped at one day, subject to availability and conditions.
- Standby Locates — a locator on-site while you excavate.
