Subsequent Events [Abstract]
Subsequent Events	On June 27, 2020, we temporarily closed one of our operational facilities and sponsored COVID-19 testing for employees in response to a potential COVID-19 exposure. During the closure, we cleaned and sanitized the facility, and we reopened the facility after one week. Employees and visitors were allowed to return to the facility only after negative test results were received or after a fourteen day quarantine period. Although the closure was only for one week, the disruption to our operations was longer as testing results were received slower than expected and project progress was delayed.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
