Invert elevations
logged correctly.
Record design invert, finished invert, pipe diameter, material, and slope for every manhole and pipe segment. GPS-tagged. Deviation-flagged. Sewer as-built documentation done.
What it does
Manhole & structure inverts
- Log structure ID, top of casting, rim, and invert elevations
- Design invert vs. finished invert with deviation
- Pipe diameter, material, and direction at each invert
- GPS coordinates for every manhole and structure
Pipe segment documentation
- Log slope, length, and grade for each pipe segment
- Calculated vs. measured slope — deviation flagged
- Material, diameter, and class for every pipe run
- Upstream / downstream invert pair for grade verification
As-built sewer documentation
- Sewer as-built PDF with all structures and pipe segments
- Grade verification against design drawings
- City/municipality-format as-built records
- Inspector and engineer review via shared link
QC & corrective actions
- Out-of-grade pipes flagged for immediate attention
- Low spots and reverse grades identified automatically
- Corrective action generated for out-of-spec conditions
- Pre-video camera as-built documentation
How it works
01
Set up the sewer system
Enter manhole IDs and design inverts from the plan set. Or import from CSV. Either way, the design is in before the crew hits the ground.
02
Log field inverts
At each manhole, log the finished invert and rim elevation. Deviation from design is calculated automatically.
03
Verify pipe grade
For each pipe segment, log the upstream and downstream inverts. Grade and slope are calculated and flagged if out of spec.
04
Generate the as-built
Export the sewer as-built PDF with all structures, inverts, and grade calculations. Share with the city or engineer.
Who uses this
Sewer & utility contractors
Invert documentation is the most common close-out holdout. Gradelog makes sure it's done right the first time.
City inspectors
Review invert elevations and pipe grades before the city accepts the system. Access via shared link — no account needed.
Civil engineers
Compare as-built inverts to design. Flag any pipe segment that doesn't flow as designed before it's backfilled.

Common questions
What data does Gradelog capture for sewer as-builts?
Gradelog captures manhole/structure ID, rim elevation, top of casting, invert elevations by pipe direction, pipe diameter, material, length, and slope — plus GPS coordinates for every structure. This is the standard data set required by most city and county as-built submittals.
Can I verify pipe grade against design in the field?
Yes. Enter the design slope or design invert for each pipe segment. As you log field elevations, Gradelog calculates the actual slope and flags any segment more than your tolerance away from design.
How does the sewer as-built export work?
The sewer as-built PDF includes all manholes and structures with invert elevations, pipe segments with grade, and a summary of out-of-spec conditions. Most city/county inspection departments accept this format.
Does Gradelog support storm drain and culvert documentation?
Yes. The inverts module is used for sanitary sewer, storm drain, culverts, and any pipe system where invert elevation and grade are documented. Structure types are customizable per job.
