Well, well, whatever could this be?

                                         Diagram that says "East Side"

Mystery flotsam.

I found this Sunday, at my favorite flotsam discovery locale, which shall remain secret since I always find something interesting there.

It is a two-sided laminated diagram, 11" x 17"

One side says "East Side" It has an empty box in the middle, surrounded by a total of 141 E-BEAMS.

Some of these E-Beams are identified as E-BEAM x 11'-0" and some are 13' and some are 9'. Lengthwise, they are divided into three columns and widthwise into three sections. Each section of beams appears to have two long bars holding them together. There are a number of small orange squares and a note pointing to one of them says "Drill 5/8" Hole a designated locations. Total: 64 EA."

The "West Side" looks pretty much like the "East Side" except that there's no blank box in the middle. This side has a total of 132 beams of the same dimensions. This one has the same drilling instructions but someone has corrected the spelling to "at" with a red marker.

Nobody who's seen it can guess what it is. At first glance, it looks like a structure that is covered with a lot of wooden pallets. Maybe that's what it is -- a pallet-type of platform that would go on a ship and cargo would go on top.

If anyone reading this can solve the mystery, do let me know.
