Eastman Chemical Company Bridge Inspections

Promo Icon 2 Updated

In May of 2010, the Eastman Chemical Company opened a state-of-the-art plant dedicated exclusively to the production of Eastman Tritan™ copolyester. The new plant, located at the Company’s Kingsport headquarters, will boost production of the high-demand material commonly used in the manufacture of popular sports and houseware products. Integral to the success of the new production facility is the condition of the existing infrastructure at the Kingston plant – namely the railway bridges which transport both incoming supplies and outgoing products. Eastman Chemical Company chose Modjeski and Masters to evaluate the condition of their vital railroad bridges.

Modjeski and Masters performed an in-depth field inspection and as-built and existing load capacity ratings of two bridges at the Kingsport plant: The Holston River and Holston Ordnance Works Canal Railroad Bridges. A complete report detailing a summary of the bridge condition, inspection findings, ratings and recommendations augmented with photographs and drawings was provided to the Eastman Chemical Company.
