There was lots to clean up after a very successful day yesterday.

Rain Showers Throughout the Day

We need to state that rain showers occured throughout the day today.  Yesterday was a bit windy, but dry.  The window for shotcrete was narrow and we managed to squeeze through it successfully. 

We’re still smiling after enjoying clear weather yesterday.

The conveyor helped to remove the concrete quickly today.

Logistically, we had 90 yards of concrete so 10% spoils is a significant amount.  Bill Brown’s team removed as much by hand as possible and then brought a conveyor in today.  This accelerated the clean up dramatically. (more…)
