CITY OF EUCLID <br />Water Pollution Control Center Facility Improvements <br />Euclid, Ohio <br />The overall project consisted of phased construction to convert the <br />City's wastewater treatment plant (WWTP) facilities to a membrane <br />bioreactor (MBR) plant to address CSO peak flows. In addition to <br />the CMAR role, Kokosing was the selected Trade Contractor for <br />multiple phases with subsequent awards for subcontractors. <br />Phase 1: Edgecliff Relief Sewer. The new Edgecliff Relief Sewer <br />provide an emergency bypass for peak flows beyond a one year <br />storm event of 213 MGD. This phase was subcontracted for $3.2 <br />million. <br />Phase 2: Headworks Site Preparation. This phase included mass <br />excavation of dirt and shale, installation of H-pile and lagging <br />wall, 96-inch RCP storm sewer relocation and construction of a <br />new cast -in -place concrete influent chamber. This phase was self <br />performed for $6.6 million. <br />Phase 3: Headworks Facility & Wet Weather Equalization Basin. <br />The new headworks complex provide coarse screening for flows <br />up to 213 MGD, fine screening, grit and grease removal and flow <br />metering for flows up to 66 MGD discharging to the future MBR <br />WWTP. Kokosing self performed this phase for $47.7 million. <br />Phase4A: MBR Procurement. Kokosing evaluated theconstructability <br />and construction cost of up to three MBR alternatives; assisted in <br />negotiating the scope of supply for the selected alternative and <br />purchased the equipment at the negotiated price of $26.4 million <br />for incorporation into Phase 4B. <br />Phase 413: WWTP Upgrade to MBR. Installation of a new MBR <br />process within existing WWTP tankage to treat peak flows up to <br />66 MGD. This phase was self performed for $52.3 million. <br />• 1V.TJ 0 17'AL*V a[ • <br />
