Question: Does Baltimore use Harbor Pilots ? ALSO, Knowing that probability that a given harm may occur is Low but its severity is High... are Tugboats ever used to assist with large vessels maneuvering though and near important infrastructure? If not, should they? Do other ports do so?

Some of these historic old churches in New England, do not have the membership to even support heating the building let alone the hundreds of thousands of dollars that they actually need in maintenance…. (Not all, but some) I know of a few with under 30 members trying just to keep the lights on.

Miracle Temple Church (Aka former 2nd Congregation Church) https://maps.app.goo.gl/rKpAWEqNqEmguqxk7?g_st=ic

I took a few photos of a similar church in New London Ct and I was amazed at what I saw.

Yes I get it, but Jeff lays out everything that i know of locally with the Collapse so far….

Some interesting commentary on possible causes of the collapse from Jeff Ostroff https://youtu.be/2F9tDefJbJ8?feature=shared

Photo of the steeple leaning back towards its roof long before the collapse.

Yes, the steeple fell into the church’s roof bringing that down as well as part of one of the side walls.

Throughout the TOWN OF SURFSIDE memo (ref Date: July 7, 2021) it REPEATABLY STATES: "after GPR to AVOID reinforcing steel" when taking concrete core samples... The M.C. Oct. 2020 report shows core samples that were taken of the C.T.S. pool deck concrete slab cutting completely through multiple...

How do we not have simple safety lockouts to prevent this is beyond me. I know that these trucks need to be able to maneuver at the job site with the dump raised but there has to be a solution to this. And clearly the solution would need to be a passive one, not one requiring the driver to...

Yes they are on the DWG and the smaller further away columns do not support the building, they were supporting the pool deck. .

Possible initiating event to look at. Failure starting at the pool slab construction joint after 40 years of failed waterproofing - corrosive chlorides concentrated through a pathway directly to top layer of reinforcement (that were under tension) corroding each of the rebars until the slab...

I found this video to have some the best detail (resolution) of some of the reinforcement that I could find. Look at the concrete pool deck slab edge in the first screen capture... . . . Video Link: https://youtu.be/Mfelq1OnyBQ?t=47

. Frequency illusion, also known as the Baader–Meinhof phenomenon, is a cognitive bias in which, after noticing something for the first time, there is a tendency to notice it more often, leading someone to believe that it has a high frequency. (a form of selection bias) Engineers understand...

Yes there are limitations on what information GPR can provide to us and reinforcing bar diameter information would be one of them. As with all NDT each method has its strength and weakness. But what GPR is exceptional at is identifying if rebar IS present and Accurately (+- 1/4”) identifying its...

How do you "add Title"? [Hint I copy & past, but that wasn't clear at 1st.] Is there an other way?

It's hard to see the [Pool/Outside SLAB Elevation change] but look at the conduit go up at 45 degrees... it changes right there. . .
