Evening travelers passing by the campus will see lights shining brightly in the Albert Sherman Center because a second shift of construction work has been added and there is now an overnight presence in building for security purposes. The second shift runs from approximately 3:30 p.m. to 11:30 p.m., six days a week, with several dozen workers in the building at that time. “We are using the second shift to accelerate progress on some of the mechanical systems. Right now the focus is on the air-handling duct work,” said Michael DiBacco, project executive for Suffolk Construction. After the second shift ends, a security team remains in the building overnight, making regular rounds, so the lights are kept on for their needs. “We are heating the building now. We have water, power and pressurized systems inside, in addition to a lot of equipment and materials, so we need to have a presence in the building 24-7 to maintain safety and security,” DiBacco said.
