Massachusetts construction sites and manufacturing facilities will be allowed to resume operations as soon as they adopt strict new cleaning and distancing standards announced today by the Baker administration.

Office and lab buildings statewide will be allowed to reopen May 25 except in Boston, which has a June 1 reopening date, while retailers can begin offering curbside pick-up May 25.

“It bears repeating that Massachusetts has been one of the hardest hit states in the country… and we must be cautious and vigilant as we reopen,” Lt. Gov. Karen Polito said at a press conference today.

The administration released guidelines enabling the reopening of office buildings, labs, construction sites and manufacturing facilities that comply with new distancing, hygiene and operations standards to limit the transmission of the COVID-19 virus. Businesses are required to complete a written COVID-19 control plan, to be available on the premises, and the state posted a sample two-page template on its COVID-19 response site.

The standards will be enforced by state and local health agencies and the state Department of Labor Standards, Polito said, noting that employee complaints will be a key enforcement trigger. The safety checklist for construction projects says cities and towns will be allowed to require big, complex projects to pay for an independent inspector who will report to local officials on safety conditions.

Officials urged employers to continue work-from-home policies to reduce capacity of buildings to 25 percent of occupancy levels, reconfigure workstations for distancing and install partitions between those that cannot be moved apart.

The order lifts the two-month-old moratorium on construction, which has been restricted on a statewide basis to housing, public works and health care-related projects.

Under the new guidelines, contractors’ COVID-19 officers will submit daily reports to owners on compliance. Workers will be encouraged to avoid face-to-face meetings and maintain six-foot distancing, frequently wash hands and use sanitizer and self-report COVID-19 symptoms or contact with an infected person.

Manufacturers will be required to reconfigure workstations to maintain six-foot distancing between employees as practical, reconfigure common areas and stagger lunch and break times. Employees will be required to wear masks and limit use of elevators and vehicles by more than one person.

In April, Baker convened a group of 17 public health, academic and business leaders to put together a blueprint for gradually lifting the restrictions on business operations and public gatherings during the initial COVID-19 surge.
