4 Eastern & Delta Avenue Phase 1 Project Status as of August 31, 2010 Project ID Little Miami Design Consultant CH2M CH2M Hill Hill Inc. Tunnel Tunnel Partners Partners The scope of Phase 1 includes upsizing and relocating the sewer interceptor and the installation of real time controls (RTC) to retain wet weather flows in the interceptor. New Vandals cut the exposed wires on the RTC for the sluice gate actuators. -The hatches on the RTC are not locked, creating a safety and liability hazard. Ongoing CM is working on a change order request to extend substantial completion date. The RTC is complete except for fencing, testing, and final restoration. The area between MHs 3 and 5 is being used to stage materials, and MH 4 is now part of the Phase 2 scope, so restoration may be delayed for some time. MH 8A has not been installed. A COR has been written to document the decision to eliminate the manhole. Restoration will continue throughout September. The schedule reflects a substantial completion date by early October.

5 Eastern and Delta Avenue Phase 2 Project Status as of August 31, 2010 Project ID Little Miami Phase 2 of this bundle involves extension of the intercepting sewer to two new CSO facilities. The two new facilities will provide High Water / Dry Weather protection when Phase 3 is completed. The new CSO locations are near the intersections of Widman Ave and Hoge Street and at Woodbridge St and Stanley Ave. The project includes approx. 2,700 feet of 18 to 48 diameter sewer. Tunneling resumed in mid-august and is currently more than half complete between MH 2 and MH 1. Open cut installation is underway at Woodbridge Place. Excavation at MH 7/8 did not begin on schedule, but sufficient float remains to compensate. The contractor is investigating the use of a smaller shaft in order to alleviate some of the conflicts with existing utilities. Design Consultant Tony Yee CH2M CH2M Hill Hill Inc. Jay Dee Tunnel s PartnersInc. New Existing electrical service and a telephone trunk line was expected to be relocated near the intersection of Widman and Hoge. The is investigating this and facilitating the best solution. Tunneling will continue in September.

6 Wastewater Treatment Plant Incinerator Project Status as of August 31, 2010 Project ID This scope includes construction of a new incinerator at the Mill Creek Wastewater Treatment Plant, and demolition of the old plant. New Excessive sulfur in the sludge is causing emission tests for Fluidized Bed Incinerator #1 to fail. Reliability Testing continues while the high sulfur content is being investigated. Ongoing The insufficient water volume and pressure in the fire system is a supply problem, not an equipment failure. It may not be able to be resolved. The city inspector may approve the test results anyway. Several valves on the waterline feeding the fire pump were found to be fully or partially closed. The fire pump was retested but a flow of 150% of design pressure still could not be achieved. The contractual completion date was 7/1/10. The contractor submitted a letter 7/9/10 requesting more time (to 9/29/10). Float decreased in August to less than 9 (now 88 days). However, the schedule health indicator was not changed to CRITICAL because the contractor s schedule shows less than 45 working days remaining.

7 Wastewater Treatment Plant Grit Removal Project Status as of August 31, 2010 Project ID Manager Bill Melissa Lutz Holscher Manager Steve Rick Jones Hartoin Kevin Deinlein CH2M Hill Ribway Engineering Group Inc. Tunnel Partners Kokosing Inc. Start 12/31/2010 Met Complete 06/30/ Days This project consists of demolition and reconstruction of the grit removal facility at the WWTP. New The contractor has made a claim of $2,100 per day for the cost of the pier driving machine that has been idle on the site, due to discovery of contaminated soil, since the submittal for test piers was returned on 7/13/10. MSD plans to negotiate with the contractor on an acceptable cost per day. -The change in disposal plans has had other impacts on both cost and schedule, resulting in several CORs. Disposal of contaminated soil is ongoing. Soil suitable for backfilling is being stockpiled. Pile drilling was completed for the tower crane and the primary influent conduit. Two CORs were issued in August, one for Ribway to design an overflow structure for the south raw sewage force main and one to establish the unit cost for hauling and disposal of special waste. The mast for the tower crane is being erected, demolition of the existing grit facility continues, and excavation for the new facility is ongoing. This work will continue in September. Due to the contamination issue, excavation will take longer than originally planned. Phase Legislative Budget An updated schedule was submitted on 7/30/10. The full impact of the contaminated soil mitigation on the overall schedule should Actual be (Current assessed $) next month Current after EAC the contractor 2006$ submits EACa Time Impact Analysis.

8 Wastewater Treatment Plant Secondary Treatment System Project Status as of August 31, 2010 Project ID Bill Melissa Lutz Holscher This project is an upgrade of secondary treatment facilities at WWTP. New None for August. Ongoing During core drilling for the RAS Piping, some embedded electrical conduits were hit, with no resulting disruption of service. HC Nutting has been contracted to x-ray the service tunnel slab to attempt to locate electrical conduits for the area where concrete repair remains. This work must be done before the contractor will complete concrete repairs. All underslab work in Clarifier 1 west, including slab replacement, has been completed. Below slab pipes have been tested. Core drilling in the tunnel has progressed with no reports of interference with existing conduits. The majority of saw cutting and excavation has been completed. Several CORs and WDCs were issued during August. While a few are for actual work changes, some adjust cost for credits and for the added cost of disposing of contaminated soil. Continuing work in Clarifier 1 includes installation of launders, baffle plates, weir gates, and sludge collector equipment. Underslab work in Clarifier 2 West is progressing ahead of schedule, as is work in Aeration Tanks 1 West and 2 West.

9 Winton and Sherwood Pump Station Consolidation - Phases 1 & 2 Project Status as of August 31, 2010 Project ID & Springfield Township Jim Curry Len Bauer Tracy Foster CH2M Hill Stantec Consulting Services, Inc. Tunnel Partners Howell s, B&J Electric These projects will replace Winton 1, Winton 2, and Sherwood Pump Stations with a single new pump station, and include installation of gravity sewer and force main. New None in August. Ongoing It has been some time since the contractor has submitted a phase schedule, but the project is near completion and no further updates are expected. A preliminary test and startup of the new pump station was performed on 8/5/10. Actual startup (with reps from WWT) occurred 8/18/10. All systems appeared to operate properly. Punch list items include installation of remaining pipe near the existing pump stations, demolition of old pump stations, and restoration. Despite various delays, the contractor projects substantial completion well before the milestone date of 12/31/10. The contractual completion date (7/20/10) was not met, and it is projected that the work to complete the project will take an additional month, although float remained the same this month.
