 After two architectural firms refused the contract to make Plensa 's design a reality , the firm Krueck and Sexton Architects accepted . Public art was a departure from Krueck & Sexton 's residential and corporate office @-@ dominated portfolio , which includes buildings like the <unk> Institute . Collaboration between the artist , architectural team , and consultants proved to be crucial to the success of the project . The fountain 's black granite reflecting pool measures 48 by 232 feet ( 15 by 71 m ) and has an approximate water depth of 0 @.@ 25 inches ( 6 @.@ 4 mm ) . It displays videos on two LED screens , each <unk> in a glass brick tower measuring 50 by 23 by 16 feet ( 15 @.@ 2 by 7 @.@ 0 by 4 @.@ 9 m ) . The firm designed a special stainless steel T @-@ frame both to bear the load of the walls , which are 50 feet ( 15 m ) high , and to withstand lateral wind forces . The frame holds all the glass blocks and transfers the load to the base in a <unk> pattern . <unk> measuring 0 @.@ 5 inches ( 13 mm ) in diameter anchor to the structure and project into the frame for lateral stability , while triangular corner brackets add support .
