Overview

Summary

The City of Aurora, IL is seeking a qualified contractor for the dredging of Mastodon Lake. This project includes the of dredging of the accumulated sediment from 23-acre Mastodon Lake using hydraulic dredging methods, dewatering and hauling of dredged materials, installation of mechanical mixing and aeration devices, installation of culvert pipes, as well as other miscellaneous appurtenances all in accordance with the plans and specifications.

Note that this is the reissuance of a previously published bid request, with changes to the dewatering and final placement locations including:

• Site 6 is no longer a bid alternative but can be used at the contractor's discretion for dewatering only. While bidders can assume that this location will be available for dewatering, the City is currently finalizing negotiations for it's use with the school district and therefore reserves the right to eliminate this location altogether.
• Site 7 has been identified and must be used as the primary dewatering site. A pay item for leveling the site and preparing it for dewatering operations has been included. After successfully dewatering the materials, the contractor will shape the dry material in accordance with the plans.
• Site 8 has been added as an additional dewatering site to utilize at the contractor's discretion.

Background

Phillips Park is considered the jewel of the community. Mastodon Lake, which is in Phillips Park, provides stormwater detention and is used by boaters, anglers and bird watchers and admired by park visitors. However, the Lake has developed an issue with excessive aquatic vegetation which is reducing the aesthetic appeal and negatively impacting the water quality of the Lake.

The City is requesting that bidders provide a proposal for completing the work outlined in the plans, which includes the hydraulic dredging of 50,000 cubic yards of wet material and dewatering in up to eight locations (Sites 1-8) along the lake within City and privately owned property. Site 7 is the location of a permanent stockpile for the dried dewatered materials. In order to reduce the need for trucking of materials to the permanent stockpile location, the contractor must fully utilize Site 7 for dewatering to the maximum extent practicable prior to using any other dewatering location.

Since the City has also published a separate bid for Shoreline Stabilization, the awarded contractors may be required to work concurrently onsite.
