For now, they (technicians) are talking about failures in the foundations.

Demolition is also in the skill set of the sapper (combat engineer).

Yes, like the USCGC Munro (WMSL-755), a Legend Class Coast Guard cutter as seen from the Aloha Tower in the Port of Honolulu, Hawaii:

We've managedto go seriously off track here!

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

We reached the end of the bridge, so to speak.

No word on the demolition, but (google translated)
. . .
Metal bridge installation begins

On the Cusiana road, kilometer 84 of the Sogamoso - Aguazul road, in the jurisdiction of Pajarito, the installation of a metallic bridge began to replace the concrete bridge located over the Negra ravine, in the Cusiana cross-section.

The bridge has similar characteristics to those installed on the Bogotá - Villavicencio road, with a length of 42 meters and a maximum capacity for vehicles of up to 52 tons.

A friends' daughter was an armorer in the CG. "My gun shoots over the horizon" she said

The horizon is only ~3 miles on flat ocean, small-arms carry almost that far. The oft-denigrated "weak" 5.56 NATO reaches ~80% of that distance, 7.62 a bit more, which is why the military places a major emphasis on shooters "owning" every round fired to prevent collateral damage.

It doesn't look dissimilar to the bridge that collapsed in Palau in 1996, which I recall was an unusual sort of creep-induced collapse.

I believe she was talking about the 5 in gun...

The problem with sloppy work is that the supply FAR EXCEEDS the demand

 

[TugboatEng]

I did get to tour the below decks and watch the gun dry fire on a 378' cutter once. Quite the machine, one arm feeding a round in and one arm taking the shell out. Everything was conveyor fed to and from the gun. I think it was 120 rounds per minute. 3 inch shells.

Continuing this minor digression, consider the 8" (200mm) guns on the USS Salem:

https://www.youtube.com/watch?v=gHR_O12-064

10 rounds per minute, 9 guns

90 rounds per minute. One every 2/3 second.

firing rate of the current 5" gun is 16-20 rounds per minute:

https://www.navy.mil/Resources/Fact...ticle/2167864/mk-45-5-inch-5462-caliber-guns/

and for the 3", about 80 rounds per minute, though 120 shows up elsewhere:

The USCG has some of the best snipers in the business - probably the only ones trained to hit moving targets from moving platforms. This is usually disabling outboard motors on drug runners from a helicopter.
