Chassis Split Per Diem Dispute Compilation: Drayage TMS Systems

Intermodal drayage carriers routinely receive thousands of dollars in wrongful chassis per diem invoices from equipment providers when rail ramps or marine terminals refuse bare chassis returns, forcing extra split legs to off-dock depots. Strong Tower Consulting designs automated dispute package compilers that aggregate gate interchange receipts, depot rejection timestamps, and dispatch mileage logs into uncontestable IEP per diem waiver filings.

Since 2008, Strong Tower Consulting has specialized in transportation systems architecture for complex operational exceptions. Our chassis split automation framework eliminates the manual evidence chase that consumes dispatch and billing staff time while dramatically improving dispute success rates.

Core Architecture of an Automated Chassis Split Dispute Compiler

The system is built as a lightweight, event-driven microservice that sits alongside or inside your drayage TMS. It listens for specific transaction patterns that indicate a forced split and begins evidence collection immediately.

High-Level System Flow (text representation)
Terminal Gate Out (Inbound Loaded) ---> Rejection Event Detected
          |
          +---> Capture Interchange Receipt + Timestamp
          |
          +---> Create Dual-Transaction Lockout Record
          |
          +---> Monitor Next Dispatch Order for Split Leg
          |
          +---> Capture Depot Drop Receipt + GPS Mileage
          |
          +---> Assemble Dispute Package (PDF + JSON)
          |
          +---> Transmit to IEP via API or EDI 214/240

This architecture ensures zero latency between the rejection event and evidence capture, which is critical because most IEPs enforce strict 7- to 14-day dispute windows.

Required Data Elements and Source Mapping

Data Element Primary Source Secondary Validation Dispute Package Field
Chassis Number Gate Interchange Receipt (EDI 322) ELD GPS Snapshot Equipment Identifier
Terminal Rejection Timestamp Terminal API or OCR Gate Ticket Driver Mobile App Free Time Expiration
Rejection Reason Code Terminal System (e.g., "NO BARE RETURN") Dispatch Notes Root Cause
Split Leg Order Number TMS Dispatch Record ELD Hours-of-Service Log Extra Movement Proof
Depot Arrival / Drop Timestamp Depot Interchange Receipt GPS Geofence Event Return Completion
Total Extra Miles ELD Mileage Log TMS Rate Matrix Cost Impact

Strong Tower normalizes these fields across disparate systems so the resulting dispute package meets each IEP's exact formatting requirements.

Integration Workflows with Drayage TMS and Supporting Systems

Our compilers are designed to integrate cleanly with existing technology stacks. Typical integration points include:

Because Exspeedite is a sister company under common ownership, carriers already using the Exspeedite load board benefit from pre-built connectors that accelerate deployment.

Implementation follows our proven TMS Implementation methodology, typically completing in 10-14 weeks from kickoff to production.

Linking to Rate Matrix and Network Optimization

Accurate chassis split data feeds directly into broader network decisions. Captured split frequency and cost by terminal, equipment provider, and lane can be used to adjust your carrier rate matrix and to negotiate improved free-time rules with steamship lines and railroads.

This intelligence also informs fleet sizing models for intermodal drayage operations and can be shared with brokerage partners under 3PL and brokerage agreements to improve overall supply chain predictability.

For carriers that also run specialized or heavy-haul divisions, the same evidence engine can be extended to support chassis and trailer dispute workflows in those segments.

Frequently Asked Questions

What is a chassis split in intermodal drayage operations?

A chassis split occurs when a rail ramp or marine terminal refuses to accept a bare chassis return, forcing the drayage carrier to complete an extra leg to an off-dock depot. This second transaction often triggers per diem charges from the equipment provider even though the carrier had no control over the refusal.

How do automated dispute package compilers reduce per diem costs?

Automated compilers continuously monitor gate transactions, capture interchange receipts, depot rejection timestamps, dispatch logs, and driver notes. The system assembles these into a standardized, audit-ready PDF package that is transmitted directly to the IEP within the dispute window, eliminating manual evidence collection that typically takes 4-6 hours per dispute.

What data sources are required for a complete chassis split dispute package?

Core sources include: inbound gate interchange receipt with chassis number and timestamp, terminal rejection code and free time expiration, outbound dispatch order showing the forced split leg, depot arrival and bare chassis drop receipt, GPS mileage logs proving the extra distance, and any driver remarks or photos. Strong Tower systems normalize these across multiple TMS and ELD platforms.

Can this solution integrate with our existing drayage TMS?

Yes. Our architecture supports direct API or EDI integration with virtually any modern drayage TMS, including those already using Exspeedite load boards. We have delivered production integrations with four leading drayage platforms in the past 24 months.

How quickly can we expect ROI from an automated per diem dispute system?

Carriers with 50+ power units typically recover the entire implementation investment within 90-120 days through recovered per diem waivers. One client recovered over $187,000 in the first six months after deployment.
