The South Cobb tunnel is a 9,150 m-long, 8.2 m-diameter tunnel with a concrete lining, construction and drop shafts, inlet structures and smaller connector tunnels. The project also includes a lift station to convey wastewater flows from the tunnel to the South Cobb water reclamation facility. When operational in 2013, the tunnel will replace existing wastewater infrastructure and provide conveyance capacity for build-out of the basin. Visit http://water.cobbcountyga.gov or www.cobbwater.org.

The tunnel was designed by Jordan Jones & Goulding. A prequalification for construction will be advertised within the next six weeks. Bids will be taken in summer of 2007. The contract is to be awarded in October 2007. Tunnelling may begin around the end of 2008. A hard rock TBM will be used to bore the tunnel. Visit www.jjg.com

The project is located in the Piedmont region of the southeastern United States. In general, the geology of the Piedmont in the greater Atlanta area consists of medium-grade metamorphic rocks that have been intruded by granitic rocks in some places. A key characteristic of the Piedmont region is the thick mantle of residual soil and partially weathered rock that overlies fresh bedrock. This mantle commonly ranges from three to over 30 metres thick. The soil zone typically forms the upper 60 to 80% of this weathered mantle. The transition zone forms the remainder. The soil zone consists of residual soil plus any overlying alluvium, fill, or colluvium that might be present locally. The transition zone consists of highly fractured rock that is structurally degraded by chemical weathering that penetrates deeply into the rock matrix. The bedrock zone lies beneath this mantle and consists of both fractured and solid bedrock.
