Jordan, Jones & Goulding, Inc. (JJG), working
with CH2M Hill Inc. and Precision Planning
Inc., provided program and construction
management for phase one of the F. Wayne
Hill Water Resources Center in Gwinnett
County, Georgia. This $250 million project
involved moving two million cubic yards of
earth, installing 21 miles of pipe and placing
90,000 yards of concrete and 10,500 tons of
reinforcing steel, installing 50,000 electrical
switches and connections, and pulling 675
miles of electrical, phone, and instrumentation cable through 100 miles of conduit.
For Phase Two Expansion, JJG again teamed
with CH2M Hill Inc. and Precision Planning
Inc. to provide design and construction management. When this second phase is completed in 2007, the plant’s capacity will increase
to 60 million gallons of reclaimed water
every day. That is nearly 42,000 gallons per
minute. Phase Two is one of the largest public projects ever for Gwinnett County.
The plant is one of the few water reclamation
facilities in the southeast that uses ozone as a
disinfectant. It returns highly treated effluent
to the Chattahoochee River.
The design schedule for all four contracts
was met using Bentley AutoPLANT software.
The end result was a more accurate set of
documents with fewer issues during construction and attendant savings in time and
money to JJG’s client. The 3D models are also
being used by the contractor, with Bentley’s
Explorer software, to visualize construction
sequences that will minimize disruption to
existing plant operations and reduce overall
construction time. ;
