mr. berkowski who came into his position in the last few months, i in no way suggest that you or mr. reiskin or he has any responsibility for where we are today. but it is kind of a mess. and the fact is we are moving down the path with a $117 million sfmta project, a $70 million public safety radio project, a $78 million bay web project when it's possible that we could have two systems rather than three. one thing i just want to say to mayor's budget office, i very much hope we will not make any long-term decisions on a 69, $70 million public safety radio until we've done the analysis with the consultant and understand where we can go and figure it out from there. >> thank you. should i continue on with my presentation? so, i think we left off with the public service radio replacement. again, we've actually talked about this quite a bit. we're estimating that would be probably 5 to $6 million to replace the radios. infrastructure costs are -- pardon? oh, we need the slide on, please. thank you. the infrastructure costs would be determined, but again this consultant we would bring on
