we held a procurement process in 2014 and selected carollo engineers. planning and engineering services initiated 2015 and the initial contract was for $14 million. during the last 12 months we did planning and preliminary designed and identified additional scope items so that the facility can function as we are intending. bring up the next slide john, and the issues really are we are extreme grit loading that comes into the collection system. we characterized it on testing and get six more times peak loads than any other treatment across the country and this unanticipated level of grit means we need a more robust handling and removal system and adds to the construction cost or control. the baseline odor model and studies show there is a higher level of control to meet our sfpuc levels of service. we have other facilities that are 70 years scpold in the construction we will have seven other construction projects going on concurrently so coordination is required to develop a construction scream because we will inserting this structure. you can see how im
