If you have already installed Project Server you can do this.
As mentioned here , You can reference to this library again by just going into this path and select the dll file.
%ProgramFiles%\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI\Microsoft.ProjectServer.Client.dll
%ProgramFiles%\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.ProjectServer.Client.dll
