The state Department of Administration has placed safety barriers and scaffolding outside a pair of new state buildings on Jones Street, including the Nature Research Center, after discovering pellet-sized pieces of glass that have broken off some window panes.
Glass has fallen inside and outside the new science museum and the adjacent Department of Environment and Natural Resources building, said Chris Mears, DOA spokesman. The cause is uncertain.
Most of the small pieces have been found inside the buildings, which have tall vertical panes. Out of 5,000 panes on the two buildings, 16 are affected, Mears said.
No injuries have been reported, and no public areas of the museum are affected. The barriers are designed to keep people 15 feet from the building.
The two buildings are connected and are known as Green Square in part because of their energy efficiency. That includes high efficiency glass on both buildings that minimizes the amount of solar heat inside.
Preliminary investigations suggest that the glass is breaking in the frame and that the installation is not the cause. Samples of the frames have been sent to a laboratory for testing.
