Summary:
Summary
The purpose of this project is to repair and rehabilitate the HDPE pipe lined perimeter ditch with an underdrain system that conveys stormwater/leachate to Pond A. During heavy rainfall events in the past few years, multiple areas had slope failures along the bank of the lined ditch in the southwest corner of the BWA Landfill. The goal of this project is to reconstruct the ditch slopes and reinstall the HDPE liner.
Body
Background Information:
The BWA Landfill is located in Pinellas County and is surrounded by a slurry wall, which is keyed into the confining clay layer. This ditch slope with the HDPE liner was constructed in 2012 and suffered through many heavy rain events. In 2017, the bank slope experienced slope failure underneath the line. While multiple repairs were made to this section of the ditch bank by removing the liner on the side slope, replacing and compacting common fill in the side slopes and reinstalling the liner, the slope failure continued to occur. The need to repair the HDPE liner and slope stability was identified after extensive research and investigation on the cause.
Three bids were received with David Nelson Construction Co. recommended for award as the lowest responsive and responsible bidder in the amount of $1,348,200.00.
