Q: How much material was removed from the Engineering Building's rooftops to make way for the new roofing system?
A: A little more than 70,000 pounds of rock/material were removed from the building's rooftops, which took about two days. "The building stands up taller now," said Kavik Frol, assistant project engineer of energy projects in Facilities Services. Frol said that the gravel roof system was very difficult to repair. The new roof, which is referred to as a Modified Bitumen system, will be much easier to maintain.
