Clay / Eric, Please see the attached price for the addition of the 3” brick ledge to the Grotto which will reduce the stone quantity, but add a substantial amount of work for the concrete contractor. The total SF of stone saved is unknown at this time, but we will only bill what is installed. Thanks Zach Fusilier North Texas Contracting 4999 Keller Haslet Road Keller, Texas 76248 Office - 817-430-9500 Cell - 817-819-6691
