Pennsylvania Gov. Tom Wolf announced April 24 that construction projects in the state will be allowed to resume May 1, one week earlier than his administration had previously announced.

The governor’s announcement came with strict guidelines on how construction work can be conducted safely to mitigate the potential spread of COVID-19.

Some aspects of this guidance differ depending on the conditions of the project, but all construction workers will be required to wear face masks and maintain proper social distancing as much as possible and will be provided with a hand-washing station on every job.

Businesses will also be required to identify a pandemic safety officer for each project or work site.

For residential construction projects, where workers would be confined to an indoor space, no more than four workers will be permitted on the site at a time. This excludes anyone who just needs temporary access or is not part of the main crew.

Wolf’s announcement continued, “Contractors performing work at the direction of the commonwealth, municipalities or school districts should defer to those public entities to determine what projects may continue.”

The state also explained municipalities may implement stricter guidelines, with which construction companies will be obliged to comply.
