Project Overview - Baltimore Harbor Tunnel
Location: Baltimore, MD

Hardesty & Hanover performed investigation on high priority repairs for the Harbor Tunnel electrical and mechanical systems. Investigation included operational issues related to several exhaust fans, failure of an exhaust damper, mechanical issues related to the interference of an exhaust fan where the impeller was hitting the inlet cone, and mechanical issues related to the blower fan impeller contacting during operation.
During the investigation Hardesty & Hanover performed visual inspections, reviewed as-built documents and recorded motor operating measurements. Based on these results Hardesty & Hanover made repair recommendations, some of which were implemented.
