Case Study: D.H. Griffin Wrecking Co. achieves 10,400 extra driver hours per year and a 70% efficiency boost with Trimble Fleet Management

Fleet Management Lifts Roadblocks for demolition company

D.H. Griffin Wrecking Co., a leading U.S. demolition firm with roughly 500 vehicles, faced inaccurate, handwritten mileage logs that cost time, productivity and ultimately resulted in fines during an IFTA audit. With trucks routinely crossing state lines and new Hours of Service rules to meet, the company needed a reliable, auditable way to capture mileage and duty status for regulatory compliance and payroll.

D.H. Griffin implemented Trimble’s cloud-based Fleet Management with Driver Logs to automate mileage capture, duty-status changes and real-time alerts (speeding, off-hours use). The company gained immediate benefits — one hour saved per driver per week (10,400 hours annually for 200 drivers), the equivalent of one staff salary saved, reduced violations and windshield-claim exposure, improved billing accuracy, and an overall reported 70% increase in efficiency.
