From first manhole to final as-built — in the same shift.

Set up the job with structure IDs and design inverts

Before the crew starts laying pipe, the field supervisor opens Sitemark and creates the job. Enter the structure IDs (MH-1, MH-2, MH-3, etc.) and load the design inverts from the plan sheets. You can enter these manually or import from a CSV — one row per manhole with ID, rim elevation, and design invert in and out.

Once the job is set up, Sitemark knows the design grade for every pipe run between manholes. The crew can start logging immediately from any phone or tablet, online or offline.

Log invert elevations at each manhole

As each pipe run is completed, the field tech takes invert shots at the upstream and downstream manholes. Enter the invert in and invert out elevations directly in Sitemark. The app instantly calculates:

- Pipe grade percentage - Comparison to design grade - Pass or fail vs city specs (±0.10 ft vertical tolerance is the standard — Sitemark applies your project's specific tolerance)

Every shot is timestamped and linked to the field tech's name and the pipe laser or level used. No paper. No re-entry in the office.

Log depth of cover at each station

Once the pipe is bedded and partially backfilled, depth of cover readings are logged at each station. Enter the surface elevation and the pipe crown elevation — Sitemark calculates depth of cover and compares it against the minimum specification (typically 36 inches for water, 48 inches for sewer depending on municipality and pipe material).

Stations that fail minimum cover are flagged automatically. The field supervisor sees a live map of which stations are passing and which need correction before final backfill. Catching a cover problem before the trench is backfilled costs almost nothing. Catching it after the inspector arrives costs thousands.

Auto pass/fail vs city specs — every run, every station

Every invert elevation and depth of cover reading is automatically compared against the design specs for that specific pipe run. Sitemark applies:

- Grade tolerance: ±0.10 ft from design invert (configurable per job) - Minimum slope: 0.08% minimum for gravity flow - Minimum cover: per pipe material and jurisdiction specs

Pipe runs that pass show green. Pipe runs that fail show red with the specific reason: high invert, low invert, insufficient slope, or inadequate cover. The project supervisor sees the full job status in real time — no need to chase the crew for status updates.

Generate the MH-to-MH As-Built PDF

When the pipe run is complete and all inverts and cover readings are logged and passing, the supervisor taps "Generate As-Built." Sitemark produces a professional MH-to-MH As-Built PDF in under 10 seconds.

The report shows every manhole on the run with rim elevation, invert in, invert out, pipe length, grade percentage, depth of cover, and pass/fail status. The format matches what city inspectors and municipal engineers expect at project closeout.

No overnight office work. No waiting for the survey crew. The as-built is ready to submit before you demobilize.
