Alvine Engineering was contracted to provide mechanical, electrical, plumbing and fire protection systems design for the renovation of the popular Apostle Islands’ Raspberry Island lighthouse. Unoccupied since for several decades, the Park Service now sought to provide quarters for seasonal staff.Prior to beginning the interior and exterior architectural restoration, the engineering systems were upgraded or replaced. Included in the scope were an upgrade of the plumbing systems, ventilation, an upgrade of the existing power system, and a complete fire sprinkler system.

The engineering team provided for sustainable operations of the site by utilizing such elements as a 12 volt electrical service based on the photovoltaic solar panels which were installed. The new septic tank’s leech field reduces the amount of waste water sent to a treatment plant or expelled into Lake Superior. The seasonal fire protection system is drained to the adjacent yard for use as irrigation.

This portion of the restoration was completed in 2005 at an estimated construction cost of $960,000.
