The project that I am involved in requires personnel to travel to the site from every corner of the globe. Most 90+% of the people must travel by plane to get close, and then take a train, bus, or catch a ride to make it the remainder of the way. None have reported any unusual travel difficulties.
Also, there have not been any delays in obtaining the procurement items we need. Many of the steel components we use are made in the United States as that is a quality control demand by the client.
