Sewer
Tenders expected September, 2001 for Gwinnett County 1.8 km-long x 3.4 m-outside diameter tunnel through Piedmont geology in mixed face and soft ground conditions. Visit www.jjg.com 32/01.The Gwinnet County Department of Public Utilities has awarded a contract to Parsons Brinckerhoff to design a new wastewater transport and storage tunnel adjacent to Snellville, a suburb of Atlanta. As prime consultant for the project, Parsons Brinckerhoff is responsible for preparing a preliminary engineering report and conducting public meetings on the proposed design. The firm will complete final design and assist the county with the bid tendering process. PB will also provide construction management and engineering services during construction of the tunnel.The tunnel, which will be 3.66 m in diameter, will begin at the No Business Creek water reclamation facility and extend for 4,880 m to the shaft at the site of the existing Jack's Creek water reclamation facility. The project will enable the county to decommission the Jack's Creek facility by directing the sanitary flow from the Jack's Creek sewershed to No Business Creek by gravity. The tunnel will collect sanitary flow from another sewershed along its route, reducing power costs to the county by minimizing pumping.It will be driven in rock with a dewatering pumping station in the mining shaft at No Business Creek. There will be two access shafts along the tunnel length with sanitary flow admitted to the system at the upper shaft, at one of the intermediate access shafts, and at the dewatering pumping station. The upper shaft will also provide access and tunnel venting for odour control.Construction on the project is expected to commence in January 2005 with final completion scheduled for December 2007. Visit www.pbworld.com 02/04.The 4,880 m No Business Creek tunnel is still under design with 95% design complete. The tunnel will connect the 30-year-old No Business Creek and the Jacks Creek wastewater plants, that are being closed. Sewage will be pumped through to the F. Wayne Hill Water Resources Center near Buford. The tunnel will mostly follow Springdale and Everson roads, which run east to west, but it will also have to pass under private property. The county is in the process of acquiring subsurface easements from roughly 54 property owners. Finished inner diameter is 3.66 m. There will be four shafts: main shaft (12.2 m diameter and 55 m deep), exit shaft (7.6 m in diameter and 18 m deep) and two intermediate shafts around 4.6 m in diameter and 39 to 46 m deep. Bidding process to start in three to four months, with construction slated to begin in the summer of 2005. Very hard rock, mostly granite and gneiss. RQD some where around 35,000 to 45,000. 85% of the tunnel through hard rock and 15% through mix phase. A TBM will be used. The tunnel may need a maximum of 15% to 20% lining (concrete segmental rings, shotcrete and rock bolts). Mucking-out with loco and muck cars. Construction time to last 36 months, including all four shafts and one lift station. Visit www.gwinnettcounty.com 48/04.Gwinnett's Department of Water Resources on 19th March approved a USD54.2 million contract with a joint venture between Mole, Jay Dee, Kassouf and Murray Hill companies to build the 4,880 m, 3.66 m-diameter No Business Creek wastewater storage tunnel 60 metres below the surface. The tunnel, which will be bored with TBM machinery, will connect the Gwinnett County’s Jacks Creek sewage treatment plant with the now-defunct No Business Creek sewage plant site. From there, south Gwinnett’s sewage will be pumped to the F. Wayne Hill Water Resources Center in Buford. When the project is complete in 2010, the Jacks Creek plant will be shut down, as part of the county’s long-range plan to close its smaller, less-efficient facilities. Entrance shafts will be constructed at the No Business Creek and Jacks Creek water reclamation facility sites and also at the site with two intermediate shafts along the route. Crews will be drilling through hard rock 95% of the way. Click us/62. Visit www.co.gwinnett.ga.us, www.molecon.com, www.jaydeecontr.com and www.kassouftunnel.com 13/07.
