OSHA Excavation Permit. Contractor shall obtain an OSHA excavation permit, including an <br />inquiry number from "Underground Service Alert". <br />Summarized herein is suggested phasing for construction activities: <br />1. Submit shop drawings and obtain permits; <br />2. Phase I: Construct 15-inch and 8-inch sewer main and manholes from connection at Harbor <br />Boulevard to Roxey Drive and test main and manholes. Do not divert flow into new main. Construct <br />new manholes over existing 8-inch laterals and maintain lateral through manhole. Construct service <br />laterals partially across the street to the limits of the traffic control. Install inflatable plugs and <br />temporary caps in service laterals at Sta. 92+20, Sta. 93+67, Sta. 94+32, and Sta. 95+68. <br />3. Phase II: Starting from Harbor Boulevard and working east to Sta. 88+50, continue constructing <br />service laterals and clean-outs and connect new service lateral to existing service lateral. Break and <br />remove the existing laterals constructed through manholes, divert flow into new IS-inch sewer <br />main, and construct a brick and mortar plug in the outlet no longer being used. <br />4. Phase III: Break and remove the existing lateral constructed through new manhole Sta. 89+26.3 <br />(Sta. 9+86.5 Clinton) and divert flow into new 15-inch sewer main. Maintain flow from South <br />Clinton into existing 12-inch sewer. Construct new 8-inch sewer to the south within limits of the <br />traffic control. <br />5. Phase IV Break and remove the existing lateral constructed through manhole Sta. 92+78.4, divert <br />flow into new 15-inch sewer main, and construct a brick and mortar plug in the outlet no longer <br />being used. Break and remove the existing lateral constructed through manhole Sta. 96+18.5 <br />(Sta. 9+86.5 Roxey) and divert flow into new 15-inch sewer main, and construct a brick and mortar <br />plug in the outlet no longer being used. Re-channel the manhole base at existing manhole <br />Sta. 96+18.5 and divert upstream flow at Roxey Drive into new 15-inch sewer, and construct a brick <br />and mortar plug in the outlet no longer being used. <br />6. Phase V. Working east to west from Sta. 96+18.5, construct laterals and clean-outs and connect <br />new service laterals to existing service laterals at Sta. 92+20, Sta. 93+67, Sta. 94+32, and <br />Sta. 95+68 (Type B laterals) and connect new service laterals to existing service laterals. <br />7. Phase VI: After all flows upstream of existing manhole at Sta. 9+71.8 (Clinton) have been <br />transferred to the new 15-inch sewer, make final connection of 8-inch sewer picking up flows from <br />South Clinton. Temporarily plug upstream manhole on 8-inch sewer, remove manhole, and make <br />final connection. <br />P:\P00597\0086\WordPm\04\CoumpondenaMo02-2013-02-19-rev.doc (300)
