Intermodal Marine & Rail Chassis Pool Reconciliation:
The Strong Tower Daily Dwell Standard (2026)

The Chassis Pool Invoice Chaos

Drayage motor carriers routinely overpay between 12% and 18% on chassis rental invoices from major pool operators including DCLI, TRAC Intermodal, and Flexi-Van. These overpayments stem from three primary failure modes:

• Misreported or missing gate-in timestamps at marine and rail terminals
• Off-hire delays that extend daily rental charges beyond actual equipment control
• Double-billed street turns where an empty import container is immediately reloaded for an export move under a different ocean carrier account

Traditional monthly sampling methods used by most dispatch teams cannot keep pace with the volume of EDI 214 status messages, gate transactions, and per-diem invoices. When your drivers are running 8-12 moves per day across multiple terminals, even a 2-day billing error per chassis creates significant leakage that flows straight to the bottom line.

The Strong Tower Daily Dwell Standard™

Strong Tower Consulting has developed an independent equipment lifecycle auditing framework that eliminates guesswork. The Strong Tower Daily Dwell Standard combines automated TIR gate-in/out timestamp capture, street-turn matching logic, and variance reconciliation against actual telematics records.

Core Components

1. Automated TIR gate-in/out timestamp capture: High-precision equipment interchange events are recorded through CheckPoint, our sister company's web-based interchange verification platform. Every gate transaction is captured electronically with second-level precision, eliminating reliance on paper interchange receipts.
2. Street turn matching: The system automatically terminates ocean carrier pool billing the moment an empty container is turned into an export load for another account. This prevents duplicate daily rental fees that commonly occur when two different steamship lines bill the same chassis for overlapping periods.
3. Automated variance reconciliation: Electronic chassis invoices (typically received via email or EDI 210) are audited line-by-line against actual dwell records stored in your TMS - whether Exspeedite, McLeod, TMW, or Truckmate. Discrepancies trigger automated dispute chargebacks with supporting CheckPoint timestamp documentation.

This process runs daily, not monthly. The result is continuous expense control rather than after-the-fact damage assessment.

Establishing UIIA Audit Defense

The Uniform Intermodal Interchange and Facilities Access Agreement (UIIA) provides the contractual framework that holds chassis providers accountable. However, enforcement only works when motor carriers maintain irrefutable evidence of actual equipment control periods.

CheckPoint's electronic gate records, combined with your TMS driver settlement and fuel surcharge data, create a complete audit trail. When a dispute is filed, the combination of EDI 214 status messages, CheckPoint timestamps, and SQL-derived dwell calculations from your operational database typically results in immediate credit issuance by the pool operator.

Strong Tower Consulting works with both asset-based drayage carriers and freight brokers managing dedicated fleets. Our methodology is TMS-agnostic and focuses on data integrity across McLeod, TMW, Truckmate, and custom SQL schemas.
