We passed the steel inspection this morning and were pouring concrete by the afternoon. After we passed the inspection the crew installed a few screeds to help guide how deep to pour the various footings since they are all at different elevations.
|The wood board in the foreground is the screed for the higher footing, there is another one beyond for the lower footing|
The structural engineer specified 3000 PSI concrete and specified that we provide 'test cylinders' to prove the concrete was mixed to the appropriate strength. The concrete will need to cure for 28 days first before it reaches it's maximum strength.
This video is from the beginning of the pour. It takes about twenty minutes or so to unload a full 10 cubic yard truck of concrete - we had three full trucks today...
