APT Management, Inc restores Lowell Sun Building’s 10-story façade with Thornton Tomasetti

APT Management, Inc. faced the challenge of restoring the historic Lowell Sun Building, a 10-story residential property, while addressing significant structural and façade deterioration. They enlisted the services of Thornton Tomasetti to provide structural engineering and architectural expertise for this complex renewal project in Lowell, Massachusetts.

Thornton Tomasetti conducted a detailed façade and structural assessment, identifying areas requiring immediate stabilization. Their solution involved comprehensive restoration, including masonry repair, lintel and windowsill replacement, and the reinforcement of spandrel beams and columns. A major achievement was the successful replacement of a severely corroded five-story corner column while the building remained occupied. The project preserved the building's historic aesthetics in collaboration with the local landmarks commission, ensuring its continued use and structural integrity.
