We are about to design a elastomeric bearing pad replacement project. It will require the lifting of 26 concrete girders at one time. The girders are about 100 feet long. Do you think this is possible or have you ever done this? Also, this is an extremely well traveled bridge so one of the constraints is that they would like to limit the work time to lift, change the bearings and lower the bridge to 5 hours. Do you think this is enough time? I think it is but it will be costly.
