Boston mayor Marty Walsh ordered the suspension of all construction projects citywide for a minimum of 14 days as Massachusetts grapples with increasing cases of COVID-19. Suffolk County, where includes Boston, currently has 51 confirmed cases of the coronavirus. "We want to make sure those workers are safe," Walsh said at a press conference. "This is a difficult decision ... and we're not taking this closure lightly." The mayor acknowledged that the city had been experiencing a construction boom of late, with tens of thousands of ongoing projects. In response to the closure, the Associated General Contractors of America released a statement condemning the move. "Halting construction activity will do more harm than good for construction workers, community residents, and the economy," said CEO Stephen Sandherr in a press release. "Given the precautions already in place, halting construction will do little to protect the health and safety of construction workers. But it will go a long way in undermining economic vitality by depriving millions of workers of the wages they will need over the coming days." [NBC Boston]

In Brescia, Italy, Italian 3D printing startup Issinova has designed and printed respirator valves for a hospital that had run out of the life-saving technology used for COVID-19 patients in intensive care. Initially introduced to the hospital by a journalist covering the outbreak, Issinova founder Cristian Fracassi offered a prototype made through additive manufacturing when the hospital's supplier was unable to provide the necessary devices. "They tested it on a patient and they told us that it worked well, and so we ran again back to our office and we started to print new valves," Issinova mechanical engineer Alessandro Romaioli told BBC News. The company printed 100 valves in 24 hours. [BBC News]
