WENDY compared: verified as-built documentation instead of manual entry
Why WENDY instead of plain documentation tools? Because in trenchless pipe-laying, documentation is only as trustworthy as its data source. General construction-doc tools like Phase0, Valoon, Memomeister, PlanRadar or Capmo document well but don't know the machine – their as-built data is only as accurate as what a person types or photographs. HDD and civil-engineering data systems like TRACTO Boredata, DCI DigiTrak or Vermeer know the machine but aren't documentation platforms and are tied to their own hardware. WENDY closes exactly this gap: verified as-built documentation straight from robot telemetry (BOB and BUDDEL via MQTT), embedded in a complete, vendor-independent platform for planning, execution and sign-off. Machine truth and documentation platform in one.
WENDY delivers verified as-built documentation from robot telemetry (BOB/BUDDEL via MQTT).
Side-by-side by capability
Four properties decide it in trenchless pipe-laying – and only WENDY combines all four.
| Solution | Machine data / telemetry | Verified as-built chain | Vendor-independent | Documentation/project platform | In brief |
|---|---|---|---|---|---|
| WENDY | Yes | Yes | Yes | Yes | Verified as-built chain straight from open robot telemetry (BOB/BUDDEL via MQTT) – machine truth plus a complete platform. |
| Phase0 | No | No | n/a | Yes | AI site diary from photos and voice messages sent via WhatsApp – no machine or telemetry connection. |
| Valoon | No | No | n/a | Partial | Structures WhatsApp communication into a project file – proves who wrote what, not what the machine did. |
| Memomeister | No | No | n/a | Yes | Digital project file with photos, videos and reports – manually created memos instead of sensor data. |
| PlanRadar | No | No | n/a | Yes | Plan/ticket-based defect and task management (strong in building construction) – no telemetry input. |
| Capmo | No | No | n/a | Yes | Construction management, defects and site diary for GCs/SMEs – no telemetry input. |
| 123erfasst | No | No | n/a | Partial | Civil-engineering time tracking, site diary and dispatch – telematics for equipment/GPS only, no drilling telemetry. |
| TRACTO (Boredata) | Yes | Partial | No | Partial | Secures drilling data to DVGW GW 321 from the Grundodrill display – device-bound, no integrated vendor-independent documentation portal. |
| DCI DigiTrak LWD | Yes | Partial | No | No | Log-While-Drilling generates as-built bore profiles from the Falcon locator – tied to DigiTrak hardware, focused on the bore profile. |
| Vermeer Projects | Yes | Partial | No | Partial | Bore planning and as-drilled capture rod by rod – within the Vermeer/DCI ecosystem, no open documentation portal. |
| Herrenknecht / VMT | Yes | Yes | No | Partial | Automatic as-built survey with web-based data management – but for microtunneling/TBM and tied to Herrenknecht machines. |
Yes = fully available · Partial = limited / hardware-bound · No = not available · n/a = not applicable (no machine data)
Class 1: general documentation tools
Phase0, Valoon, Memomeister, PlanRadar, Capmo and 123erfasst document via manual entries, photos and messages. They are strong at defects, tasks and reporting – but have no input for machine or sensor data. The as-built data stays only as accurate as what a person records.
Class 2: HDD / machine-data systems
TRACTO Boredata, DCI DigiTrak LWD, Vermeer and Herrenknecht/VMT log real drilling/machine data – but tied to the device (Grundodrill, DigiTrak locator, their own rigs, TBM) and focused on the bore log, not on an end-to-end, vendor-independent documentation platform.
Price positioning
WENDY starts at €49/month (net, B2B). That is below many per-user documentation tools – publicly the vendors list, among others, Phase0 at €80/user/month, Capmo from approx. €50/user/month, PlanRadar €26–129/licence/month, Memomeister from €19/user/month and 123erfasst €12–18/user/month. Among the HDD data systems, DCI DDM costs approx. $295/year and TRACTO QuickPlanner3D €606/year. And WENDY delivers machine data that none of these documentation tools has.
DVGW GW 321: documentation duty as a selling point
The DVGW code of practice GW 321 requires drilling logs (Annex E) and daily site logs (Annex D) for certified companies in group GN 2 (steerable horizontal directional drilling). WENDY fulfils this documentation automatically and verifiably from the machine – instead of having it retyped by hand.
Market: large, regulated and growing
Depending on the research house, the global HDD market is put at roughly USD 8–10 billion (2023/2025) with an annual growth rate of about 7–11.75%. Germany is regarded as a key market of the energy transition: industry studies cite an announced infrastructure investment volume of more than €500 billion (electricity, hydrogen, district-heating and fibre networks), and the upcoming grid-expansion projects alone involve around 4,500 crossings.
Market sizes shown as a range from several research houses (ResearchAndMarkets, MarkNtel, Fortune Business Insights); the €500 billion and 4,500-crossings figures are infrastructure and demand indicators (rbv/S&B Strategy, Herrenknecht 2025), not a software market size.
