Water Control Structure L-4 Rehabilitation - Change Order 1 Emergency Repair of Unforeseen Condition
Divert the Belleaire/Royal Palm Waterways through weir structures at B-1, B-2, and B-3 Dewater the area adjacent to L-4 Weir with sheet piles Determine the nature and extent of the problem Decide on a course of action and repair the unforeseen condition Repair the unforeseen condition Restore the flow ways of the Belleaire/Royal Palms Waterways Rebuild the weir structures at B-1, B-2 and B-3 Scope of Work
Divert the Royal Palms and Belleaire Waterways through the weir structures at B-1, B-2 and B-3.
Determining the extent of the unforeseen conditions
Three dimensional modeling indicated that the void had a volume of approximately 110 cubic yards
Filling the void with 110 cubic yards of flowable fill through inch holes that were drilled in the weir deck
