Plot underground assets from your Dial Before You Dig plans. Everyone on your team draws onto the same live map — then screenshot it straight into a CivilSnap dig permit.
The plans arrive. Then everyone marks up their own copy.
A BYDA response lands as a stack of flat PDFs. One person reads them, marks up a printout or a screenshot, and that markup lives on their laptop. The designer, the supervisor and the crew each end up with a different picture of the same street.
Subsurface gives you one map to draw on. Trace the services once, in layers, and the whole team is looking at the same ground — with pot holes, permits and bookings on top of it.

Shared layers
Trace it once. The whole team draws on the same map
Build a layer for each service — asset type, sub-type, owner and material, with its own colour, thickness and line style from solid through to wavy. Trace along the road with the line tool and drag a mid-handle to add a bend. Drop point symbols for pits, chambers, valves and hydrants, each sized and rotated to suit. Nothing snaps — features go exactly where you put them — and undo covers every draw, move, reshape and status change.
Before

One person's copy. Flat, and out of date the moment it is filed.
After

Everyone draws on it. Toggle any layer on or off.

Overlays on your drawing
Pot holes and permits, on top of the plan
Plans are indicative. A pot hole is fact. Switch the pot-hole and permit overlays on and your traced services sit against real photographs of what the crew actually exposed — depth, GPS and the moment it was taken.

CivilSnap is the field app behind the map. See every screen a crew works through.
Record who the work is on behalf of, your reference, the dates, whether it is design or excavation, the workplace locations and activities. Set it Planned, Active or Complete. Everyone else working the same ground can see it.

Drawn on the map
Draw the work area on the map and it sits alongside every other booking in your workspace, so overlapping windows are visible before anyone mobilises.
New build
The map shows what is designed and what is actually in
Turn on new build and draw. Every line carries its own state, so nobody has to ask whether that run went in last week or is still on paper.

Callout areas are drawn as polygons over the ground they apply to, and toggle independently of your service layers.
Bring your own data
You do not have to draw everything by hand
Where a dataset already exists, pull it in. Where it does not, trace it once and the team has it.
