Construction Manager at Risk
Atlanta Water Supply Program Phase 1A and 2 connects the Bellwood Quarry to the Hemphill Pump Station and the Clayton Site adjacent to the Chattahoochee River. It includes a 5,569 linear-foot, 10.5-foot-diameter tunnel through hard rock. Phase 2 extends the tunnel to 15,000 linear-foot to the Clayton Site where a 30-foot-diameter by 350-foot-deep shaft served as the exit location for the tunnel boring machine. The project increases the City of Atlanta’s water storage capacity approximately tenfold.
