Probably common sense to never makes any assumptions about the legitimacy of folks who post on the internet claiming expertise in one field or another.
Even if the guy does happen to be an engineer, he's not got any first direct or first hand knowledge of the issue, and is only commenting on what's been posted by other non-engineers.
But I'll just come out and say that you appear to have a personal agenda against David Broadland, one that has nothing to do with the JSB.
You have come to VV on occasion and made reference to your past roles, and I have believed you. Was I mistaken to do so? At a certain point, it's nice to have a little faith in humanity. I don't run around calling you a liar, because I trust there is a grain of truth to what you say. What's the point of this whole forum if we're going to say that we don't believe anonymous posters; most of us do post here anonymously. I think we've all earned a certain level of trust around here, and the same can be said for other social media forums like reddit.
Regardless, I don't have any particular agenda against David Broadland at a high level (what's that saying about assumptions?). I've stated my issue here quite clearly, and it is entirely related to the JSB. I've also stated that I agree with most of his points. I'm a vocal supporter of an independent audit on this entire project, and have been here on VV for a couple of years at least. My opinion on this particular piece by David is that it is counterproductive to that goal, because again, it plays to sensationalism or advocacy journalism, and that puts people off. Look at the feedback online his article has gotten. It's dramatically split down the middle of "boo Lisa Helps, not another bridge issue" and "this guy obviously has an agenda". Not a lot gets done when people are so split.
For something as important as an audit to actually happen, you need to engage both of those sides. Council needs to see it as something that everyone wants or at least can agree on. I think everyone can agree that there's been mismanagement on this bridge. That's what can pull people together, not some conjecture about whether a steel plate is a sound engineering concept. So it bothers me when David plays to that click-bait style journalism full of speculation, because it takes away from the legitimacy of something that can be agreed upon by all sides.
