The situation is changing quickly, but versatility and fast decision-making have become necessary. On March 12th, Zweig Group launched a survey to see how AEC firms are reacting to challenges presented by the situation surrounding the coronavirus (COVID-19). As of March 20, 133 firms from nearly every geographic region of the U.S., size range, and AEC discipline, had responded to the survey. The majority of the respondents to the survey were firm leaders, directors, and managers with decision-making capability in their organizations. Please note that the numbers reported below are likely to change rapidly as the situation progresses and we continue to gather responses to this survey. On Sunday, March 15, 2020, just 9 percent of firms had suspended all business travel. By March 20, 21 percent of firms had suspended all business travel, with the majority of firms (46 percent) conducting business travel on a case-by-case basis. Eighteen percent stated travel policies remained unaffected. With many organizations across all industries encouraging or requiring employees to work remotely, more than 11 percent stated they do not currently allow for any employees to work remotelyandhadnot issuedanypolicychanges in response toCOVID-19. WGI, a 600-person national design and professional services firm, was early to institute policy changes: “At WGI our number one priority is the health of our associates and their families. Our Crisis Management Team is working hard to review countless sources of information from a diverse array of experts and communicate across 18 offices in eight states in a calm, consistent, and clear voice. The reality is that there is no crystal ball that provides perfectly clear guidance on how to proceed.
