Construction

The construction sector may operate limited in-person operations in accordance with the April 17th guidance, including restricting work crews to two people per location/job and following mandatory health safety recommendations. Only construction needed to support the COVID-19 response, maintain critical infrastructure, or for the safety, sanitation and operations of residences or businesses is allowed to operate beyond this scope. As an example, replacing a failing roof, failed electrical system, or broken waterline would be acceptable. Additionally, jobsites should be left in a safe and secure manner before ceasing in-person construction. Providing services to a hospital or healthcare facility would be acceptable.

Construction crews returning to work under the Work Safe provisions of Addendum 10 and the April 17th guidance must remember that the intent of the new guidance is to reduce the density of workers at construction sites and reduce gatherings at construction sites. Construction companies must not return to “normal” operations. The April 17th guidance allows construction to occur with no more than 2 people per location/job.  A location/job may be a single property, a single house, a floor of a large multi-story property, or a distinct separate physical location on a larger construction property. In instances where more than 2 people are working on a large project (for instance, 2 people on floor one and 2 people on floor 3), those individuals must not come into contact. Start times must be staggered to avoid gatherings, breaks should be staggered, and job meetings exceeding 2 people must not occur.

The Agency interprets unoccupied to mean uninhabited properties.  Indoor construction should not occur in occupied properties, whether the homeowner is present or not.
