Bridge Maintanance and silt debris containment in fast current situation
We are currently bidding on a job where there is very high current flow. (6 knots at the tide change). The job involves restoring each of the bridge pylons from about 1 foot (0.3 meters) under the low water line to 8 foot (2.4 meters) above the low water line. The project scope also covers the under and sides of the bridge.One of the DOT compliance requirments is that the sediment and debris that will occur during the restoration of the bridge in the Florida Keys is contained and handled appropriately. What suggestions do you have for these tough conditions (6 knots of flow). I will upload some photos to for you to see what the job site looks like. I am concerned that if we use the standard thinking and approach to turbidity control we will certanmy run into a problem with the curtain being ripped up. Please help.
