WCFD Station 51 & Station 52 assisted West Whiteland Fire Company on this incident. Story & pictures from West Whiteland Fire Company:

At 8:18AM The West Whiteland Fire Company was dispatched to the 800 block of E. Lincoln Hwy. in the new neighborhood under construction for a commercial building fire. The West Whiteland Township Police Department arrived to find heavy smoke showing.
Employees tried to extinguish the fire with an extinguisher prior to calling 911, unfortunately giving the fire time to grow. Initial arriving crews stretched two hand lines to the first and second floors. Crews found fire coming from the floor of the second floor. An attempt was made to extinguish the fire, but the fire had already spread throughout the void space between the two floors. Due to collapse concerns crews were ordered to evacuate the building. The fire continued to grow rapidly and reached gas lines. Eventually the fire reached the attic space and caused a collapse of the HVAC system on the roof into the second floor. Crews then went into defensive operations with master streams. The fire was placed under control in just under an hour and a half. Crews cleared the scene at 1 PM after extensive overhaul.
