In the alleyway between two buildings on K St, an existing tower for a dual kitchen exhaust that extended alongside 15 stories of the building needed to be moved around to the front to comply with property line restrictions. ADI was able to remove the existing tower and furnish and install a prefabricated duct that needed to be craned into place on the face of the building. This project was completed under very tight schedule - from start to finish, ADI completed this in less than 8 weeks.
