The Italian city of Milan, still in total lockdown in the region of the country hardest hit by the coronavirus, has restarted work on all three tunnel sections of its new $1.8-billion Metro line 4 subway, mobilizing some 200 workers. All construction had been halted by regional COVID-19 legislation for 10 days last month.
To prevent virus infection on site, the joint venture of Salini Impregilo S.p.A. and Astaldi S.p.A. have introduced measures such as twice daily body temperature checks, safe distance working rules and the use of masks and hand sanitizers. A new law to fight COVID-19 transmission requires infrastructure projects to adopt such safety measures before resuming work.
