Just another quick thought about controlling utilities. For some reason I have found that sometimes crews are a little reluctant to shut off gas to the building. Especially when presented with a gas meter setup like the one pictured below. If you have time you can trace the pipe and try to isolate the specific meter needed, or you can do my favorite and just shut them all down. I understand that this may make things more difficult for the building owner and gas company, but it’s a little bit of piece of mind to the outside team to be able to confidently say “utilities secure.” Beware of the meter bypass line that may make it appear the line has been secured, again when in doubt, turn them all off! You can’t see it in the picture but their may be one valve (behind the milk crate) that would shut the entire riser down at once. -Jimm-
