Site Administration Coordinator and Construction Site Coordinator/ Foreman are not the same jobs. If you read the JD, most of the responsibilities of this position have nothing to do with the construction site. In fact, only one of them is and that is, to "Process the issue/addition and removal of access control cards for contractors and employees, as required"
In the UK, 'Contractors' is the most common term used for teams of workers used on commercial construction sites.
