Clay, I've attached a corrected version of Vitruvian Change Order #2 for your use. I separated Item CO2-1 into three parts; two are for the lightning protection at each bridge and the third is for conduit and conductor at Bella. While I have an appropriate quantity for the length of the irrigation conduit that was added to Bella (201 LF), this item also includes additional conduit and conductor for lighting circuits. Therefore, I left the unit as LS. I'm concerned that by using the linear quantity I'd be suggesting a unit price that would not be representative of this item. Feel free to call me to discuss this further. Eric Eric S.

CO1-1 needs to be broken into components. There was the 2 each lightning protection at $35,402.18 apiece and then the conduit under the bridge at $___ per linear foot (the total should be $7,579.44 and the # of linear feet from the plans). With these corrections, it looks good to go. Thanks for your help on this! Clay Barnett, P.E.
