FLORIDA DREDGE AND DOCK LLC
Subcontractors: Bruce Stahl Excavating, Inc. and Ardaman and Associates, Inc.
Previous Projects: Lake Panasofkee, Sumpter County Florida
Methodology: Project approach started with the state’s acquisition of the property for the CDF.
Ardaman will then follow with Field Sampling and Basic Design for the CDF; and then follow
this with the permitting. Ardaman scheduled six months for the permits. Proposed schedule
would require the dredge to operate seven days per week and twenty-four hours per day in order
to complete 600,000 cubic yards of transfer to the CDF in calendar year 2014. With early
acquisition of additional disposal areas, dredging beyond 2014 would be accomplished during
daylight hours.
The dredge identified for this project by Florida Dredge and Dock LLC would pump thru 16”
O.D. HDPE pipeline to additional boosters on shore as needed. Final booster count and location
would be determined after final spoil site selection. In general, the system would require an
additional booster for each 8,000ft of horizontal distance to the CDF or 100ft of vertical lift. For
this project, anytime the location of a potential disposal area met the requirements for another
booster it will add $1.00 per cubic yard of dredging.
Equipment: 14” Ellicott model 770E Dragon Dredge; 2 Steel Hull In-Board Diesel Work Boats
– the “Jupiter” and the “Tarpon”; D6 CAT Dozer; PC300 Komatsu Track Hoe; A 28’ X 60’

Subcontractor: Cook, Flatt, & Strobel (CFS) Engineers
Previous Projects: Lake St. Louis Hydraulic Dredging, Lake St. Louis Community Assoc., St.
Louis, MO; SEMO Port Hydraulic Dredging, SEMO Port District, Mississippi River, Scott City,
MO; Holcim Harbor Hydraulic Dredging, Holcim Cement Company, Bloomsdale, MO; Fabius
Levee District Hydraulic Dredging, Fabius Drainage and Levee District, West Quincy, MO
Methodology: Upon Award, will order bonds, then have CFS Engineering acquire permits and
work closely with necessary state and federal agencies. CFS will design the CDF based on
topography. Once permits are acquired work would begin on the CDF. The CDF would be
constructed of earthen berms to enclose the area of a 3 cell system in which the dredge slurry
will be pumped to. Water exiting the CDF would be monitored for turbidity and suspended
solids.
The dredge, boosters, pipeline, etc. would be mobilized to the site in February 2014. Dredging
would be conducted for 150 work days/year, running a single 10-hour/day shift. Once a CDF
site is at capacity clean water would be pumped out and stoplogs removed to allow dewatering.
Then final grading and seeding would be completed.

Methodology: Upon Award, would acquire appropriate permits and work closely with
necessary state and federal agencies. The dredge equipment mobilization and setup will begin in
February 2014.
ENVIRON proposed to use the Genesis method as opposed to constructing a CDF. This would
allow for dewatering of the dredge material then placing it on farmland. There will be no
dredging in the winter months.

THE ROSS GROUP CONSTRUCTION CORPORATION
Subcontractors: Mike Hooks, Inc.; SAIC
Previous Projects: Blue Rose Café in Tulsa, Oklahoma, the Arkansas River; Design-Build
VOLAR Barracks Renovation - Fort Polk, Louisiana; Development of PCBs in the Scout
Reconnaissance Gunnery Range - Fort Campbell, Kentucky; Kingsville Physical Fitness
Complex - NAS Kingsville, Texas; Digital Multipurpose Range Complex - Fort Bliss, Texas
Combined Arms Collective Training Facility (CACTF) - Fort Bliss, Texas; Design-Build FY08
TRAPS Relocatables - Fort Sill, Oklahoma; U.S. Marshal Service Space Alterations Fayetteville, Arkansas
Methodology: The permitting and design process for each year would begin with receipt of
correspondence from the KWO specifying the exact locations of the CDF.
After proper erosion controls are put in place the CDF site would be cleared and leveled to a
rough grade. The layout for the CDF and the placement of the drain system would also be
marked out. The drain system would then be installed in the proper location and adequately
protected from damage during construction by installing a wood barrier with caution tape 6’
around the structure. At this time, construction of the levees and finger dikes that make up the
disposal area would begin.
After CDF is completed dredging would begin. As the dredge is assembled, a pipe fabrication
crew would fuse the poly pipe that would be used to transport the dredge material to the CDF.
Also during this time, a survey crew would perform an initial survey of the reservoir to
determine the depths and widths of the cuts that the dredge will make. The dredge would run
continuously for 200 days or until 600,000 cubic yards of sediment had been removed. The
amount of sediment removed would be determined by comparing interim surveys to the initial
survey and a final survey.
Equipment: 115’ non-self-propelled rotary dredge; 32”, 27”, 7,200 hp cutter suction dredge;
The dredge fleet is supported by a full complement of tug boats, tender boats, crane barges,
derricks and other miscellaneous attendant plant.

Project, Terrebonne Parish, LA; Dredging of Belle Pass, Lafourche Parish, LA; Phips Ocean
Park (Reach 7) Beach Nourishment Project and FDEP Hurricane Recovery; Orange Beach/Gulf
Shores Beach Restoration Project, Gulf Shores/Orange Beach, FL
Methodology: Compile Data; Conduct Initial Stakeholder Meetings; Develop Alternatives;
Research Infrastructure and Mapping. Then follow one of two alternatives to dredge:
600,000 CYs/year: The required annual quantity of 600,000 cubic yards would be achieved by
this dredge in a matter of 8 months with a minimum of labor by developing a single crew
assigned to the dredge and working a 12 hour day, 6 days / week. The required annual quantity
of 600,000 cubic yards would be achieved in a much shorter season by working 2 – 3 crews on a
24 x 7 schedule.
1,482,000 CYs/year: The second primary approach would be to evaluate the efficiency of
operating the dredge on the same annual occupancy as 1.a. above where the crew and equipment
are fully employed for about 9 months / year. According to the bidder, this allows the project to
enjoy the maximum efficiency of the equipment and crew, lowering the overall cost of the
project and completing the desired dredged quantity in approximately 40% of the time. In the
same five year period, this system and operating approach will yield approximately 7,500,000
cubic yards removed from the reservoir compared to the 3,000,000 cubic yards in the approach
in point 1 above. Royal Bean anticipates designing and constructing multiple CDF’s varying in
size and location from the reservoir.
Equipment: 16 x 16 electric dredge (Shark Class) with an overall length of 80’-10” and an
operating range of 4’ to 30’ of digging depth (would be constructed for the JRR Project); 25’
work boat/dredge tender with a 115 horsepower engine; Cone Penetrometer (CPT); Real Time
Kinematic systems; Agricultural tractors with pan scrapers; Bulldozers

SEVENSON ENVIRONMENTAL SERVICES, INC.
Subcontractors: EA Engineering; Glynn Geotechnical; Professional Engineering Consultants;
Geotec Inc.; Wastestream Tech
Previous Projects: Fox River PCB Sediment Removal, Phase I; New Bedford Harbor Superfund
Site; Emory River Dredging and Dewatering, Kingston, TN; Masonville Dredged Material
Containment Facility; Baltimore, Maryland
Methodology: Obtain Permits; Sevenson also included a cost estimate to perform the project
continuously for 3 million cubic yards. According to the bidder, the project would only require
one mobilization and one demobilization. The dredging would be approximately 71 weeks or
about 497 calendar days of dredging. For all options, Sevenson planned to dredge 24 hours per
day, five days per week. Cost savings for this option were included in the Cost Proposal package.
A second option Sevenson included in the price included development of a nearshore CDF that
would not require booster pumps along the roadways to the CDF. This option eliminated
pipeline, boosters, fuel, and maintenance. The dredging would be approximately 71 weeks or
about 497 calendar days of dredging. For all options, Sevenson planned to dredge 24 hours per
day, five days per week. As dredged materials dried out, silty materials could be trucked out and
spread on local farmer fields. Cost savings for this option were included in the Cost Proposal
package.

Previous Projects: Crystal Lake and Clear Lake Dredging – New Hampton, Iowa; Lake Decatur
Dredging – Decatur, Illinois; Lake Worth Dredging – Fort Worth, Texas
Methodology: Two separate approaches based on whether the base work is awarded or whether
the optional proposal was accepted. In either case basic strategy was the same, only the dredge
and power supplies were different. Base bid: Dredge 600,000 CY in each of five consecutive
years using a 16” dredge named the Commodore. Project Permitting and CDF site location and
Design would be initial activities. CDF Construction would consist of a levee system and proper
erosion control measures would be put into place. While construction of the CDF is moving
forward the dredge and pipeline mobilization would begin. Shore pipeline from the booster into
the CDF would be laid in the ditches along the county roads. Dredging would commence at a
rate of 24 hours/day 7days/week. 12 months would be needed to dewater CDF. After 2 years of
drying and grading the spoil area would be ready to be farmed.

Channel Restoration - Emerald Isle, NC; Texas City Ship Channel, Design/Build - Texas City,
TX; Cameron LNG – Hackberry, LA; Freshwater Bayou Maintenance – New Orleans, LA;
Upper Chesapeake Bay Channel Maiantencace – Philidelphia, PA
Methodology: Assist the KWO in obtaining permits; Acquire additional permits if needed.
Construct a 100 acre CDF using a seven foot dike (average height) and an outlet weir. WMI
personnel and equipment would perform this work and install the outlet weir at the appropriate
location. Immediately upon the completion of pumping into a disposal area, WMI would drain
the area by lowering the side of the outlet weir only at the rate at which clear water is released.
Dredging would commence immediately after the assembly of the dredge and pipeline and
construction of the first disposal area. Material removal would commence west of the dam in
water depths of 6 to 8 feet. The dredge would excavate northward approximately 3,000’,
removing 8 feet of material for a width of 225’. Daily hydrographic surveys would document
the previous day’s volume removed. At the completion of the 3,000’ cut, the dredge would be
pulled back, moved over, and another 225’ cut would be made. The third 3,000’ long cut would
complete the 3,000’ by 675’ by 8’ deep area and the removal of 600,000 cy. The final, after
dredging survey of the entire area would be done at this time and may show that some shoaling
has occurred in the initial dredge areas.
