Sitemark fits directly into the existing pile installation workflow. No new equipment, no workflow redesign. Just faster sign-off and cleaner documentation.
Before the crew starts driving piles, the field tech opens Sitemark and selects the active solar project. Projects are pre-loaded with block IDs, tracker row numbers, pile IDs, and design elevations from the EPC-issued pile layout. No manual data entry — the design data is already in the system.
The tech selects the block they're working in. Sitemark shows a visual grid of the block with color-coded pile status: gray (not yet logged), green (pass), red (fail), yellow (corrective action open).
Compatible with iOS and Android. Works offline — all data queues locally and syncs when back in range.
For each pile, the tech taps the pile ID on the grid (or scans a pile tag), reads the elevation from the GPS rover or optical level, and enters the actual elevation. That's it.
Sitemark automatically calculates the variance from design elevation and compares it against the EPC-specified tolerance (typically ±0.02 ft). If the pile passes, it turns green. If it fails, it turns red and a corrective action is automatically created.
GPS coordinates are captured with each check when a rover is paired via Bluetooth or USB — the pile location is plotted on a site map in real time.
Integrates with Trimble, Leica, Topcon, and Sokkia GPS rovers. Manual entry also supported for optical level shots.
When a pile fails the tolerance check, Sitemark creates a corrective action record automatically. The record captures: the pile ID, failure reason (high/low), the failing elevation, the EPC tolerance used, and the date/time.
The project superintendent receives a push notification (if configured). The corrective action is assigned to the re-drive crew. When the re-drive is complete, the tech logs the post-correction elevation. If it now passes, the corrective action is closed — the pile turns green on the grid and the record shows both the original failure and the corrected elevation.
If the pile still fails after re-drive, it escalates and remains flagged for EPC review.
Every corrective action is immutably linked to the original failed check — full audit trail for EPC submittal.
When all piles in a block show green (or corrective actions closed), the project manager taps "Generate Block Report." Sitemark produces:
1. As-Driven Pile Elevation Report — pile-by-pile table with design elevation, actual elevation, variance, tolerance, and pass/fail status for every pile in the block.
2. Block Conformance Summary — aggregate view showing total piles, pass rate (%), failed piles, re-drives completed, and a sign-off section with project name, EPC name, block ID, and completion date.
3. GPS Map Export — plotted pile locations with color-coded pass/fail markers, suitable for attaching to the EPC submittal package.
Both reports generate as PDF in under 5 seconds from field-collected data.
No desktop software required. Reports are emailed directly from the field or downloaded via the web dashboard.
The project manager emails the As-Driven PDF and Block Conformance Summary directly from Sitemark to the EPC QA representative. The package includes:
- Cover page with project name, EPC name, contractor name, and block ID - Block Conformance Summary with pass/fail totals and sign-off block - As-Driven pile elevation table - GPS location map - Calibration record for the survey instrument used - Corrective action log (open and closed)
EPCs reviewing a clean, complete package like this authorize racking installation immediately — same day, same shift. Compare this to chasing down handwritten pile logs and compiling spreadsheets the night before a deadline.
Reports are stamped with the field tech's name, GPS device serial number, and calibration date — meeting EPC QA chain-of-custody requirements.
With EPC sign-off in hand, racking crews mobilize immediately. No waiting on documentation. No emergency spreadsheet sessions at 10 PM. No last-minute calls to the survey crew asking for backup data.
Meanwhile, the pile driving crew is already on the next block. Sitemark gives you a continuous pipeline: Block A verified and signed off while Block B is being driven and Block C is being laid out. The documentation process no longer bottlenecks the construction sequence.
Project managers see the entire project status on the Sitemark dashboard: blocks complete, blocks in progress, blocks with open corrective actions, and overall project pass rate — all in real time.
At 200MW scale, keeping one additional block ahead on documentation is worth $200K+ per day in racking crew utilization.
Initial project setup takes 15–30 minutes. You import the pile layout (CSV or manual entry), set the block structure, and configure the EPC tolerance. After that, the field crew can start logging immediately with no further setup.
Sitemark supports custom pile ID formats. You can use the EPC-issued pile tags, row/column coordinates, or any alphanumeric scheme your project uses. The as-driven report uses the same ID format so EPC QA can cross-reference directly against their design drawings.
Yes. Multiple field techs can log simultaneously. Pile checks are queued locally and sync to the shared project when connected — no duplicate entries or conflicts. The block grid updates in real time for all connected users.
Sitemark exports clean PDFs and CSV data that can be uploaded to any QMS. For EPCs using proprietary systems, the CSV export contains all pile data in a format that can be imported directly. Direct API integration with specific EPC QMS platforms is available on Enterprise plans.
