National Science Foundation: COVID-19 Affected Ongoing Construction of Major Facilities Projects [open pdf - 2MB]
From the Document: "Since GAO's [Government Accountability Office] April 2020 report on the status of the National Science Foundation's (NSF) major facilities projects, the Large Hadron Collider High Luminosity Upgrade program began construction, and it along with the four other major facilities projects in construction (see figure), have weathered schedule delays associated with the COVID-19 [coronavirus disease 2019] pandemic. To partially account for increased costs associated with the pandemic, such as the cost of paying project staff while work is paused, NSF has authorized $38.9 million in total project cost increases to the award recipients constructing three of the five projects:  $18.9 million for the Daniel K. Inouye Solar Telescope,  $10.0 million for the Vera C. Rubin Observatory, and  $10.0 million for Regional Class Research Vessels. Because the pandemic is ongoing and its full effects are not yet known, NSF expects to make further adjustments to the cost and schedule of all five major projects in construction. Design work on an additional major facility project continued without significant interruption from the pandemic. Further, NSF made awards to begin the agency's first three mid-scale research infrastructure projects."
