Concrete Water Tank

[NW Mailing List]

Abram, 

While not N&W related, the following page on the Miami Conservancy has almost 4000 photos taken before and during construction of the flood control project in the late teens - thirties.  In those 4000 photos are dozens of middle - late teens concreting operations; some of railroad structures.  It does a good job of illustrating concrete construction techniques of the era, including local borrow pits, aggregate washing operations and form building.  Some of the smaller bridging operations may have been similar in size to the large concrete structure projects that Alex listed in his email.

It’s amazing what was able to be accomplished in a time when the horse was still being used as a construction vehicle.

Since I am the guy who opened this can of worms, let me add just a bit more. 

Can you imagine the logistics involved in such a construction project, back in a day predating the modern machinery available today? E.g., Fabricating the reinforcing steel, erecting the forms, getting the raw materials for 875,000 lbs of concrete on the site (which may have involved building a special siding,) discharging the ingredients (sand, lime, aggregate) from the bottom of covered hoppers, mixing it in small mixers, raising it to the pour-site with clam shells, and maintaining the mixing/pouring around the clock until the entire pour was finished? 

I'll bet the N&W gave the work of building these tanks to an outside contractor, rather than performing the work with Comp'ny forces. 

Has anyone figured out when the first of these edifices was built on the N&W? Is there a comprehensive list of how many of them existed, and were?
