Possibly I posed this question under the wrong credit. I posted it under SSc4.2 last week and didn't get a response, so am trying again under this credit. Our project is located at a large airport. The building is surrounded by tall fencing and all employees must enter by foot through the security entrance, which is at the parking lot adjacent to the building. The main door to the bldg. is approximately 145 yds. from the security entrance. No cars or bikes can go through the security gate. Since the security entrance is a forced point of entry, would this be considered our main building entrance? Thanks so much!
