Focus on Dream (sculpture) and analyze the Construction.
The Dream sculpture is built out of moulded and cast unique concrete shapes, 90 pieces in all contributing to over 14 tiers (54 individual elements for the head, each weighing 9 tonnes (8.9 long tons; 9.9 short tons)). Dolomite was utilised as a concrete aggregate in order to provide the brilliant white finish. Additionally titanium dioxide was added to the mix in order to provide a self-cleaning mechanism. The construction required the construction of individual moulds for each piece and took a total of 60 days to cast.
The foundations of the sculpture extend 125 feet (38 m) into the ground with 8 piles driven in to secure it.
