The study looked at productivity data for more than 113,000 labor hours performed by mechanical, electrical and plumbing contractors from January through May 2020 at commercial construction jobsites ranging from high rise apartments to K-12 school projects, government facilities, food and agricultural installations and hospital bed towers, as well as both new construction and retrofits.
The data showed that taking precautions and performing fit-for-duty checks before contractors enter a jobsite resulted in an 8.7% productivity loss, while following protocols on the job, such as using personal protective equipment (PPE), maintaining social distance from other workers and making sure workspaces and tools are cleaned and disinfected, led to another 9.2% productivity decline.
