CPWR has released a Date Bulletin talking about the impact of COVID-19 in the past two years.

From CPWR:

The COVID-19 pandemic has led to dramatic changes in the U.S. labor force and business practices, in large part because of high rates and numbers of nonfatal and fatal illnesses. The construction industry experienced numerous disruptions, from material delivery delays and project suspensions to concerns about future project funding. In addition, many construction firms improved workplace safety and implemented new practices, such as mask-wearing, social distancing, and more flexible absenteeism policies. After the initial waves of the pandemic, the construction industry saw promising recovery, especially in 2021. This Data Bulletin provides information on the two-year impact of COVID-19 on the industry, including changes in spending, employment, small business trends, OSHA inspections and citations, and worker safety and health. Data used come from a variety of publicly available sources, including the U.S. Bureau of Labor Statistics, U.S. Census Bureau, U.S. Department of Commerce, U.S. Occupational Safety and Health Administration (OSHA), and the Delphi Group at Carnegie Melon University (see the Data Sources section below for more information). Time periods covered by this report varied by source according to data availability.
