Learning Center
Master the principles and practices of professional OS/OW route intelligence. From survey fundamentals to advanced constraint analysis.
What is Route Intelligence?
Route intelligence is the structured understanding of whether a route can be executed safely, legally, and defensibly for OS/OW transport.
Why GPS Navigation Fails for Heavy Haul
Consumer GPS systems lack the constraint awareness needed for oversize/overweight loads. Learn why specialized route intelligence matters.
How to Survey Overheight Clearances with LiDAR
A practical guide to using LiDAR and field measurement tools to document vertical clearances for permit applications.
Auto-Routing Readiness Checklist
Before enabling automated route suggestions, ensure your survey data meets coverage, density, and validation requirements.
Running Live Dispatch from the Office
See your active field crews on a single map, push the current route directly to a driver, and capture geotagged field notes in real time with NAV Live Dispatch.
The Professional Client Handoff
Why a Driver Briefing PDF plus a versioned Client Delivery Portal link is the modern standard for handing route intelligence to drivers and customers.
Organizing Permits & Project Documents
How the OS/OW Document Center, V01/V02/V03 versioning, and Permit Application Auto-Fill keep an entire OS/OW project audit-ready from kickoff through close-out.
Planning a Move Around the Weather
Use Weather-on-the-Way to time-align forecast conditions to your planned route segments and decide when to launch, when to wait, and when to hold.
How to Survey a Low-Clearance Route for an Oversize Load
An 8-step field procedure for surveying a route with low overhead clearances — measuring, documenting, and cross-checking every constraint against the load envelope.
How to Check Bridge Clearance for an Oversize Load
How to verify that an oversize load will clear a bridge: verify the load height, field-measure the structure at its lowest point, apply a safety margin, and document the result.
What Should Be Included in a Heavy Haul Route Survey Report?
The core sections of a complete route survey report: load envelope, constraint inventory with photos, grade and geometry analysis, jurisdiction notes, and versioning.
How to Document an Oversize Load Route for a Client
How to turn a surveyed oversize route into a client deliverable: structured constraint data, a versioned report, a driver briefing, and an interactive map link.
How to Prepare a Driver Briefing for an Oversize Load
How to build a crew-facing driver briefing: route-ordered hazards, critical POI callouts with photos, escort and staging notes, and a printable format for the cab.
How to Manage Route Survey Photos and POIs
How to keep survey photos and POIs organized: capture structured POIs in the field, link photos at capture time, classify consistently, and keep one authoritative record.
What Is the Difference Between Permit Routing and Route Surveying?
Permit routing selects a legally approvable path; route surveying verifies in the field that the path physically works. Professional moves need both.
How to Compare Two Heavy Haul Routes
A structured method for comparing candidate heavy haul routes: normalize the criteria, score clearances, grades, geometry, and permit complexity, and document the decision.
Printable Checklists
Field-ready checklists you can print or save as PDF.
Heavy Haul Route Survey Checklist
A printable checklist covering pre-survey preparation, field measurement steps, documentation standards, and post-survey verification.
Oversize Load Route Planning Checklist
A printable checklist that takes an oversize move from load definition through corridor selection, constraint verification, permits, and dispatch readiness.
