Great build thread, and I appreciate some of the detail provided, in particular the addition of the banding on the water tank!

I have one comment though - while that water tank on the roof certainly makes for a more interesting roof line, I am just not sure if a shed type building like this one could possibly support a roof tank like this (without an inside support structure, that would be disproportional to the building size and impact usability of the interior of the building itself).  Assuming the water tank is 8 feet wide and 10 feet tall, the water inside the tank when close to full would weigh over 30,000lb. With that said, admittedly, it's hard to resist the charm of those rooftop tanks.

Are there some good prototype examples of roof tanks like this?

I don't want to take away from the great craftsmanship in any way, but am curious.

Thanks Curt.

Thanks swisstrain, I couldn't answer your question as far as the tank goes. I'm not a structural engineer nor did I design this kit. I like the way it looks but I'm not really sure how prototypical it is.

Hey Steve:

Looks just beautiful. Keep the pics coming.

Looking good!  That kit is coming together nicely.

I have attached an article specifically about roof top water tanks in New York City.  Certainly the same principles apply to tanks in other locations.  Obviously, any tank has to have some type of load bearing structure inside the building that is capable of supporting the tank.  HTH.

A lot of buildings have a strong central core, where the elevators (and usually rest rooms) are located.  I wonder if it's fair to say that water tanks were located over top of that central core.

Y'all are correct.....the large load from the water tank would require much more robust structural support from the columns, beams and roof structure underneath.


You're right Swiss, the tank described would hold 15.7 tns. of water, plus the weight of the tank and it's support structure. That amount of weight is much greater than the normal live and dead loads that the roof would have under normal circumstances.


And welcome to the forum.

Seems this discussion comes up every time someone builds this kit ....
So ...a tank this size is 0.56cu inches, which would only be a weight of 0.02lbs I think even though the tank doesn't really have any water in , the supporting structure could in fact probably hold the weight if it was topped off...

I have not heard from any of the modelers who have built this kit, that they have ever had any collapse or even heard any creaking of the structure.

But what if we are talking real world? (nobody said this that I could find ) ..well.... in fact the supporting posts of the tank are made of Tritanium (same stuff USS Enterprise is made of) but to keep it's identity secret , it is in fact painted as weathered wood. This goes through the building (unseen in these photos) to reinforced concrete footers ,10 actual feet into the ground. So have no fear, the tower is over engineered to handle the load.

Hi All:

Jim is correct the legs went through the roof and into footings in the ground. Sometimes the water tank was over further and two of the legs were on the outside of the building and into footings on the ground.

Hmmm...   Someone's been powering his laser from Dilithium crystals, I think....

Building looks great, nice recovering on the water tank, I'm not a fan of self adhesive either, I've grown acustomed to using 3m tape though.

Thanks for providing all the additional color on rooftop tanks, in particular Jim's, I just had to chuckle.  We will see if the roof on Steve's building will start to sag - I will check closely on the next few pictures he is providing us with.  .

Looking forward to watching the build progress!

[SteveCuster]

Thanks for the feedback everyone.

I didn't have a ton of time to work this last week but I made some progress.


I started painting a few of the castings. I use Reaper paints for painting castings. I'm using the set I got from SierraWest. I weathered the casting with some chalks after I was done painting.


I added the billboard and cut out a base for the diorama. I always paint the foam with some brown paint so I dont have any blue or pink come through.


I added some basic ground cover to start. I will add more variety and details after it dries. Obviously still wet at this point.

I'm working on some fence material now. I'll update the thread once I add them.

Thanks for checking in.
