VIENNA — On Dec. 4, the students in Pete Pietras’s Carpentry class and Danny Insley’s Electricity class participated in a renovation project for the Town of Vienna. An abandoned building in Vienna was selected to be renovated for the town’s new Dorchester County Sheriff’s Substation. DCTC Construction students volunteered to help. The Electrical students performed the following tasks: wiring the main electrical panel and installing a motion sensing light fixture for the rear of the building, ran supply power for a new HVAC system, replaced an interior chandelier style light fixture, installed an exterior light fixture near front entrance, and mounted a weather-proof exterior receptacle. The Carpentry students were tasked with squaring the entry door jamb and hanging the front door.
