RE: Contract No. 2101255
Belle Isle Seawall Rehabilitation
Vendor: Dean Marine & Excavating, Inc.
MOTION
Upon recommendation of Cheryl Porter, Chief Operating Officer - Water and Field Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Interim Chief Executive Officer (ICEO) to enter into Contract No. 2101255 “Belle Isle Seawall Rehabilitation” with Dean Marine & Excavating, Inc., at a cost not to exceed $1,039,058.63 for a duration of 715 days; and authorizes the ICEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
Contract No. 2101255 is a design-build contract that involves the design and construction of seawall and shoreline stabilization improvements at the head of GLWA’s Belle Isle intake lagoon. Severe erosion has occurred along the shoreline over the past several years due to a failed seawall. The condition has been exacerbated because of high water levels and, if left unabated, will cause additional damage to nearby structures. The purpose of this project is to improve the seawall by engineering and installing a seawall that will increase the coverage area of protection on the lagoon dike tip and is designed to withstand the water levels that have recently been experienced. Lastly, the project will restore a failed storm water collection system that is threatening to undermine the security fencing. The project will be substantially and finally completed within 545 and 715 days, after the Notice to Proceed is issued, respectively.
JUSTIFICATION
The Belle Isle Intake serves three of GLWA’s five water treatment plants - Springwells, Northeast, and Water Works Park. The existing seawall has failed, and the land will continue to erode. Improvement of the seawall is needed to prevent further erosion and failure of the seawalls and nearby structures.
