Weyerhaeuser Company announced today that it successfully launched TransWorks’ Transportation Management System at its Hot Springs, Ark., transportation site last week. The system will be used to facilitate truck transportation management for shipments of lumber and plywood.

“Our focus is to improve the speed and quality of the information we communicate with our carriers,” said Rich Heydon, Director of Truck Services. “In the first phase of this project, we are automating load tendering and shipment visibility, with a focus on identifying and quickly addressing exceptions. This will allow us to provide our carriers with real-time access to receive and send shipment information in many different formats, based on their individual preferences and technology capabilities. We will, in turn, receive much greater control and visibility throughout the shipment lifecycle.”

“We are pleased to have been selected to provide our Transportation Management System to Weyerhaeuser and their carriers,” said Tim Minnich, TransWorks' President. “TransWorks is focused on breaking down the communication barriers between shippers and their carriers. We accomplish this by automating many of the repetitive, time-consuming tasks, allowing both parties to make smarter, faster decisions based on the most up-to-date information.”
