Worthington Foundation Construction II

Here the forms and rebar are being prepared for the third pour of concrete.  This 36" deep pour would be the most complex of the project.  You can see how the forms for the first 2 pours were used once again.  They are seen here as the bottom layer in the near part of the photo with other form sections placed on top of them to make the total 36" depth.  The space in the center where the rebar does not pass through is where a section of internal forms will be placed to make the flywheel "pit".
This photo shows the construction of the forms and foundation under the cylinder end of the engine.  You can see that this third pour was actually done in four sections.  The spaces that run from the front to the back in this photo are where pipes for the engine will be.  In the passage to the left will be the steam line between the cylinders and the steam exhaust line from the engine.  The passage to the right is for the pipes connecting to the air cylinders.
Shown here is the result of the third pour of concrete after the forms were removed.  You can now clearly see the flywheel pit in the middle of the picture.  With this level completed the foundation finally reached the level of the floor in the building.
The fourth and final pour was for a raised section only under the crankshaft end of the engine.  We were able to determine why the original foundation was constructed this way.  The extra concrete under this end of the engine was intended to balance the weight with the very heavy cylinder end of the engine.  Once again the forms from the first two pours were used again with spacers attached to the top to achieve the proper depth.
Here you can see the forms for the flywheel pit reinstalled so it could be extended through this final level (shown in the upper left of the photo).  Additionally, you will notice the box in the center to leave a depression in this top level.  This is to accommodate "bulges" in the bottom of the the crank frame pieces of the engine.  These bulges are where the throw of the crankshaft is.  Another benefit of this design is that when the grout is filled in under the pieces they will be even more rigidly attached to the top of the foundation.
In October 2001 the final pour was completed.  This was a proud moment for the volunteers on hand for this big day!
Shown here is the completed foundation ready to accept the Worthington engine.

I hope the presentation here of the Worthington foundation construction has been entertaining and informative.  I also invite you to proceed on to the Worthington engine reassembly sections of this site since this is the phase of the project we are now working on!
