Alligator River Bridge Project Geotechnical Borings
A private engineering firm will be selected to conduct the geotechnical subsurface investigation for the
project with approximately 222 Standard Penetration Test(SPT) borings to be performed. These 222
borings will be performed in the corridor shown on the attached site map. We anticipate 149 bridge
borings will be located within the Alligator River to the north of the existing Alligator River Bridge and be
accessed using barge mounted drilling equipment. Approximately 40 roadway and 3 bridge borings will
be performed along the western bridge approach and 27 roadway and 3 bridge borings will be
performed along the eastern bridge approach and accessed using ATV mounted drilling equipment.
The bridge borings in the Alligator River will be advanced utilizing geotechnical drilling rigs mounted to
self-propelled floating barge or jack-up barge platforms. The floating barge platforms will be used closer
to the eastern and western shores of the river, or in shallow water as needed, and will be stabilized at
the boring locations using aluminum or steel spuds dropped into the river bottom to hold the barge in
place during drilling. Additional spud casing can be added or removed depending on the water depth
and will be extended well above the working platform to allow the barge to float up or down with
changing water levels (tidal changes). The jack-up barges will mechanically lower stabilizing spuds to the
river bottom at the boring locations and will then be used to raise the barge platform completely out of
the water and provide a stable working platform during drilling operations unaffected by changing water
levels. Each boring will advance 3-inch or 4-inch diameter steel outer casing from the barge platform to
the mudline and into the subsurface by rotation or driving creating minimal disturbance to the river
bottom. This temporary casing will be advanced as needed into the subsurface to provide borehole
stability. Any ground disturbance from the borings should be limited to within a 2-foot radius of the
boring location.The drilling and sampling of the borings will be completed within the steel casing
utilizing mud-rotary drilling methods. Drill fluids consisting of a water-bentonite slurry will be circulated
from a mud tub on the barge platform through the drill tools and drilling bit and recirculated to the mud
tub on the barge platform through the outer steel casing. Drilling cuttings (spoils)will be captured in the
mud tub, removed as necessary to facilitate drilling and sampling operations, and temporarily stored in
metal drums on the barge platform until boring termination is achieved. Upon boring termination, any
stored drill cuttings will be shoveled back down the steel outer casing and into the subsurface and the
temporary casing will be removed. Stored drill cuttings unable to be returned to the subsurface will be
brought to shore and deposited on land outside of wetland areas. The barge drilling platforms will be
launched and recovered from the marina/boat ramp shown on the attached site map. It is expected
that each bridge boring will be advanced to a depth of approximately 150 feet and will take two days to
complete. We anticipate having up to three barge mounted drilling rigs in operation and estimate
approximately 6 months to complete these borings.
The roadway and bridge borings located on land along the bridge approaches will be advanced utilizing
geotechnical drilling rigs mounted to rubber-tired, tracked, or marsh-buggy ATV platforms as needed
based on actual ground conditions. Drilling and sampling operations will be performed as described
above using mud-rotary drilling methods and tools. Any ground disturbance from the borings should be
limited to within a 2-foot radius of the boring location. Movement of the ATV drilling rigs will be
confined to the proposed alignment corridor as much as possible to minimize ground disturbance
accessing these locations. Access to the alignment corridor will be from existing access points, roads, or
right-of-way. If a proposed boring location is inaccessible to ATV drilling equipment, hand tools
consisting of hand augers and/or muck probes will be utilized to characterize the subsurface conditions

at those locations. It is expected the roadway borings will be advanced to depths ranging from 10 to 50
feet below existing ground surface and will be performed concurrently with the barge drilling
operations.
