3. Edge Hub Architecture & Security Topology
FiberBore Studio operates on an edge-computing model with zero cloud subscription costs:
- Hardware: Raspberry Pi Zero 2 W (quad-core ARM64 @ 1.0 GHz, 512MB RAM, <1.8W power draw).
- Encrypted Mesh: Tailscale Funnel creates authenticated WireGuard TLS tunnels directly to the public HTTPS domain
https://fiberbore.tail798550.ts.net. - Web & Proxy Stack: Nginx reverse proxy handles static file delivery, gzip compression, WebSocket upgrades on
/ws, and on-demand database streaming on/download-db. - Embedded Database: SQLite 3 with WAL journal mode and 20-second busy timeout at
/var/www/data/fiberbore.db.
4. Field Access & Mobile PWA Deployment

5. Operator Identity & Attribution Engine
Every bore line, handhole box, and blue stake markup is stamped with the author's identity:
- Tap the profile pill in the top header:
๐ค Field Operator. - Configure: Name (e.g. Julio), Drill Crew (Drill Canyon, Missile Canyon, Don Tony, Los Primos, CAA, Supervisor, Inspector), and Avatar Color.
- Every saved feature receives an immutable author card visible when inspected with the Select (
V) tool.
6. Directional Drilling (HDD) SOPs & Rod Math
The platform separates drilling operations into two distinct visual states:
- Planned Bore (Highlighter Mode -
B): 12px translucent vector stroke (65% opacity). Proposed engineering corridor. Underlying CAD street names, ROW lines, and parcels remain 100% visible beneath the stroke. - Actual Bore (Solid Drill Mode -
A): 5px bold solid vector stroke representing verified drilled and pulled conduit. Recalculates team production footage instantly. - Scale Calibration (
C): Click two points with a known distance (e.g. 100 ft bar scale), enter feet, and tap apply. All footage calculations update mathematically:Footage = ฮฃ โ((xโ - xโ)ยฒ + (yโ - yโ)ยฒ) ร ScaleFactor - Drill Rod Conversion: 10-ft rods (Vermeer D20x22 / Ditch Witch JT20) =
Footage / 10; 15-ft rods (Vermeer D40x55 / Ditch Witch JT40) =Footage / 15. - Minimum Depth of Cover: 36" in parkway/sidewalk, 48" under roadways, 72" under railroad tracks.
7. Telecom Box & Enclosure Inventory Catalog
FiberBore Studio strictly tracks Box Counts across standard telecom industry specifications:
| Box Code | Dimensions (WรLรD) | Standard Field Application |
|---|---|---|
| HH 24ร36 | 24" ร 36" ร 24" | Main Distribution Box: Primary lateral tie-in & customer drop terminal aggregation. |
| HH 17ร30 | 17" ร 30" ร 18" | Service Handhole: Intermediate cable pulling point along long roadway bores. |
| HH 14ร19 | 14" ร 19" ร 12" | Drop Handhole: Small-footprint residential lot boundary transition box. |
| HH 36ร48 | 36" ร 48" ร 36" | Heavy-Duty Vault / Handhole: High-capacity feeder trunk line crossings & slack loops. |
| PED | Vertical Post | Above-Ground Pedestal: Vertical stake post for flood plains or uncurbed rural ROWs. |
| FP | 10"โ12" Can | Flowerpot: Direct-buried round plastic cylinder flush with lawn turf. |
8. 811 Locate Tickets & Subsurface Damage Prevention (SUE)
- Tolerance Zone Rule: Mechanical excavation and directional drilling are strictly prohibited within 18" to 24" of locate markings without physical exposure via non-destructive vacuum excavation (potholing).
- APWA Colors: ๐ก Yellow = Gas, ๐ด Red = Electric, ๐ต Blue = Water, ๐ Orange = Comms, ๐ข Green = Sewer, ๐ฃ Purple = Reclaimed Water.
- 811 Ticket Statuses:
โข First Notice (Blue Dashed): Ticket logged; locators dispatched. Do not drill.
โข Second Notice (Yellow Dashed): Follow-up escalation; locator tardy.
โข Third Notice (Red Dashed): Emergency escalation; utility failed to respond.
โข Complete / Cleared (Solid Green): All utilities marked and cleared. Clear to drill. - Vacuum Pothole Test Pits: Record test pits with Custom Overlay (
O) โ Pothole marker, stamping measured utility depth (e.g.2" Gas @ 48" depth).
9. High-Resolution Drone Aerial Surveys & Property Defense
Pre-existing driveway cracks, damaged sidewalk flags, and dry lawn turf trigger costly homeowner damage claims. FiberBore's drone inspection feature provides pre-construction proof:
- Tap any blue helicopter pin (
๐) to open the Drone Lightbox. - Pan and pinch-zoom high-resolution orthomosaics to inspect curbs, driveways, and landscaping prior to rig entry.
- Review date/time-stamped inspector pre-construction notes to defend against illegitimate claims.
