Albany planned to develop a 16 acre mega yacht marina
on the southwest coast of New Providence Island,
Bahamas. The development includes an 18-hole golf
course, single and multifamily residences, internal
roads, and support infrastructure. Albany needed to
excavate the Marina and dredge the mile long, 150 foot
wide entrance channel. The marina will accommodate
mega yachts over 200 feet in length.
Devcon Bahamas Ltd. began construction of the marina
basin concurrent with dewatering operations allowing us
to excavate the basin in the dry, thereby increasing
productivity. The marina basin excavation provided
material to construct dredge settling ponds, which
enable solids dredged to precipitate from seawater.
The hydraulic dredging of 200,000
cubic yards of rocky and sandy material from the
entrance channel, performed by our 21 cutter-suction
dredge and support equipment, was placed in the settling
ponds. The dredged material was loaded and trucked
to varying locations for use as structural fill under
proposed buildings and roads, bedding for underground
utilities, and mass fill for the golf course.
Concurrently, the marina basin excavation continued
utilizing three (3) Hitachi 750 excavators and seven (7)
Articulated Off Road Dump Trucks. We
excavated 450,000 cubic yards from the marina basin and
transported the material throughout the development.
To complete the entrance channel,
the outermost portion was mechanically excavated using our barge and
long stick excavator. This material was removed
from the barge daily and spread and
compacted for structural fill.
Teamwork and cooperation between
Albany and Devcon Bahamas Ltd. allowed the project to
meet or exceed established milestones and provide for
continuous work of other contractors and subcontractors
with differing scopes of work.
