Airport grade documentation has to be precise, traceable, and immediately available for inspection. Sitemark makes that the default — not the exception.
Before grading begins, the QC Manager sets up the airport project in Sitemark: project name, airfield area (runway / taxiway / apron / shoulder), design grade elevations by station, allowable deviation per FAA AC 150/5370-10 (typically ±0.04 ft for primary surfaces), and compaction specification (typically 100% of Modified Proctor).
Station intervals are configured per FAA specification — typically 50-foot intervals on primary runways, 100-foot intervals on taxiways. Sitemark pre-populates the station grid so field techs log data by selecting a station, not typing one.
Setup takes 20–45 minutes for a typical airport project. Design grade CSV import supported.
The field tech arrives at each station with a level rod or GPS rover. They select the station in Sitemark, enter the actual measured elevation, and confirm. Sitemark automatically:
1. Compares actual vs. design elevation 2. Calculates deviation 3. Flags pass/fail against FAA tolerance (±0.04 ft for primary runway surfaces; ±0.06 ft for secondary areas per AC 150/5370-10) 4. Records timestamp, field tech name, and GPS coordinates (if rover paired)
Stations that fail are immediately visible on the station map — color coded red with the deviation amount displayed.
Works offline. All grade checks queue locally and sync automatically when connectivity resumes.
For each compaction lift, the tech or testing lab representative logs the nuclear density test result directly in Sitemark: station and offset, lift number, test depth, in-place density (pcf), Proctor reference number, Proctor maximum density, and calculated percent compaction.
FAA AC 150/5370-10 requires field density tests at specified intervals (typically every 500 SY for granular base, every 1000 SY for subgrade). Sitemark tracks test coverage and flags areas where the required test frequency has not been met — catching the gap before the inspector does.
Compaction records include ASTM D6938 test method reference, moisture content, and corrected density.
At the end of each shift (or on demand before an FAA inspection), the QC Manager taps "Generate Report." Sitemark produces:
1. FAA AC 150/5370-10 Grade Report — station-by-station table with design elevation, actual elevation, deviation, tolerance, and pass/fail for every station logged in the current lift.
2. Compaction Summary — nuclear density test results by station and offset, with Proctor reference, in-place density, and percent compaction for every test in the current lift.
3. Material Certification Attachment — linked certifications for materials placed in the reported area.
Reports generate in seconds from field data — no transcription, no manual table-building.
Reports are formatted to match the submittal format expected by FAA resident engineers. No reformatting needed.
When the FAA resident engineer arrives for an unannounced inspection, the QC Manager opens the Sitemark dashboard and pulls up the current lift documentation: all grade checks, compaction records, material certifications, and non-conformance reports — organized by area and date.
The resident engineer can review the complete QC record on screen or receive a PDF package by email while standing on the airfield. No scrambling, no "let me get back to you," no requests for extensions.
All documentation is timestamped, identifies the field tech who recorded each data point, and references the instrument used — meeting FAA chain-of-custody requirements.
Full QC record is accessible on any device — phone, tablet, or laptop. No VPN or special access required.
