>Would interdasting to learn if the old wooden docks where dismantled and herded together in a corral of some sort, on the water, while being dismantled and then hauled away en masse, rather than dismantle a few, haul those, rinse and repeat. Seems it would be more efficent to bring in the lorries for loading up without a lag time as the docks are broken up and moved about.
Anon, check out GoogMap. Switch to 3d satellite view. I know they use composite images but in such a close proximity check out the use of the end of the marina parking lot being used as the staging area for work done on Basin 3. VERY cool snapshot of operations going on. You can see equipment sheds, contractor's mobile office buildings, piles of what looks like "re-bar", etc. Not sure how they are using the re-bar. It's usually laid down in the concrete form and concrete poured over it.
BUT CHECK OUT WHAT GOOG-MAP 3D HAS CAUGHT, IN CLOSE PROXIMITY TO THE BASIN 3 REFURB!: Heavy equipment just across the street at (former) Edgewater Hotel. Those excavators, the type they use to tear buildings down. (Think October 2017.) In this same 3d GoogMap of the marina, they show the Seal Beach Pier in the same demo's condition as 29SEP2016 photograph I posted above. The capture by GE of heavy machinery (excavators) at the Edgewater must have been within a week or two of total demolition. If you've ever witnessed the process, they don't play around. It probably only took days to tear the hotel down. I was only being conservative giving it a week or two. That puts the GE imagery of the work on Basin 3 and demo on Edgewater between the end of September to some time in October 2017. The Edgewater was said to have been demolished in October 2017 right?
