Built for the work

Tools that respect the field.

Every screen is deliberate. Pixels placed with purpose. Numbers that are right. No fluff, no flash, and no internet required.

9 Field Calculators

Zero guesswork.

Concrete volume, rebar spacing, slope & grade, tile layout, footing loads, mortar mix, roof pitch, cut lists, stair rise/run. The numbers a foreman actually needs — none of the ones they don't.

Why JANO Field

The professional's tool.

JANO Field doesn't replace your CMMS, your BIM, or your project tracker. It replaces the napkin in the foreman's pocket — and the missed cylinder break that lands in the inspector's report.

Without JANO Field

  • Calculator app on the home screen, units guessed at, results lost
  • Cylinder breaks tracked on a clipboard pinned to the office wall
  • Plan markups happen on PDFs scattered across three email threads
  • Lightning policy: someone yells "head for the trailer"
  • Daily reports compiled at 6 PM from memory and three Slack messages

With JANO Field

  • Nine purpose-built calculators, all imperial / metric / mixed, results saved per project
  • QC Hub with auto-fired 7 / 28-day break reminders and stamped PDF export
  • One source of truth per drawing — RFIs, deficiencies, progress, all geo-pinned
  • NWS lightning alert with a 30-min countdown overlaid on every screen
  • Daily report assembles itself from today's notes, photos, pours, and weather log
Built by practitioners who understand the work at ground level.
JANO Brand Identity · v1.0
Phase 5 · Extended Intelligence Platform

From construction toolkit to AI-native field operating system.

Phase 5 of the JANO Field roadmap delivers nine extended-intelligence modules that no competitor can replicate today: real-time AR building-code analysis, AI-generated QC workflows, on-device fire-stopping AHJ compliance, intelligent spec parsing, automated weather-triggered safety stops, IoT sensor mesh, AR crane-coordination, and lone-worker heat-stress monitoring. All offline-first, Claude-powered, running on the iPhone already in every field worker’s pocket.

Multilingual AR Translator

Camera-based real-time signage translation with construction vocabulary. ML-driven bilingual signage suggestions after 3 days of usage. Tier-1 moat.

QC Template Engine

Army Corps 6-step QC workflow, AI-generated and project-history aware. Replaces clipboards and Excel for the 71% of GCs still on paper.

Fire Stopping AI + AHJ

Point camera at a penetration → AI identifies the assembly, measures annular space, suggests listed EJ system in 8 seconds vs. 25-minute Hilti tech support call.

Specs Analyzer

Parse division-by-division spec books into searchable, contract-exhibit-ready compliance maps. Estimator and PM time-killer eliminated.

Takeoff & Estimation

RSMeans-integrated takeoff suite for estimators — concrete, rebar, framing, MEP rough quantities directly from PDF plan markup.

Weather Safety Alerts

OSHA 1926.416-compliant lightning monitoring — broadcast to all crew devices in < 30 seconds when threshold crosses 6-mile NWS radius.

IoT Sensor Mesh

BLE/BAS site sensor network — temperature, humidity, vibration, occupancy — surfaced live in JANO Field with alert routing.

AR Crane Coordination

Multi-crane swing-radius visualization with conflict detection in AR. The first software replacement for radio-based crane choreography. Tier-1 moat.

Heat & Lone Worker

Wet-bulb globe temperature monitoring + fall-detection lone-worker protocol via CoreMotion + Apple Watch sentinel.

Go-to-market sequencing

Phase 5 development cost: ~15 engineering weeks · ~$7,250 in API/GPU spend (RAG + CoreML training). Primary investment is founder/Principal time. CoreML fire-stopping model trains on the Kenmore Plaza 170+ document archive on rented A100 (~$200 at Lambda Labs).

About the founder

Built from the inside out, not as a Silicon Valley guess at what a jobsite looks like.

Principal & Founder

Terrence J. Kostelny

15-year construction project manager with direct field experience on commercial, municipal, and high-rise projects. Founder of TechJano LLC and principal of the JANO Field platform. Author of the Kenmore Plaza 170+ document QC archive that anchors the platform’s domain fluency. Operator of the AgentHub ecosystem — 89 parallel project profiles, 57 Python automation tools, 150+ domain skills — that powers JANO Field’s AI capabilities.

Why JANO Field exists: Construction moves $2.1 trillion of work annually in the US, yet still runs on clipboards, disconnected apps, and manual report entry. Every feature in JANO Field traces back to a specific moment on a real jobsite where the existing tools failed. The app is built by someone who has carried the clipboard.

Company

TechJano LLC

Publisher of JANO Field. Bundle ID com.jano.field. Headquartered in the Denver metro area with the AgentHub orchestration backbone running across macOS and Windows nodes. Pending LLC formation is OAI-7 on the master roadmap.

Validation

  • Aurora Parks Department — public-sector compliance pilot in active development.
  • Kenmore Plaza archive — 170+ real-world QC documents validate every Phase 5C training prompt.
  • Phase 0 build complete — LiDAR viewer, AR overlays, glassmorphism UI shipped to TestFlight pipeline.
