I. INTRODUCTION
Provide all labor, supervision, engineering, materials, supplies, equipment, tools,
transportation, surveying, layout, and protection for the proper execution and completion
of all the work in accordance with the Contract Documents. The Work shall include but
not be limited to that shown on the plans and detailed in the quality assurance plan and
technical specifications. All work shall be conducted in accordance with all applicable
local, state, and federal standards and regulations.
II. SCOPE OF WORK •
The Scope of Work for the canal sediment removal activities located in DSR#3 (Big Pine
Key), DSR#5A (Islamorada), and DSR#5B (Marathon) consists of mechanical dredging
to remove the sediment accumulation relating to Hurricane Irma.
The utilization of the mechanical system will result in the collection of a slurry from the
canal bottom comprised of sediment and saltwater. The vessel-based dredge excavates
and places the material in a dedicated dewatering area. The contractor will utilize a
passive dewatering system to handle the dredged material. The dewatering system will be
located either in the canal on the barge or within the upland staging area adjacent to the
canal. Once dewatered the material will be transported to an approved upland disposal
location dependent on the chemical characteristics of the material.
The Contractor must install temporary construction fencing, consisting of jersey barriers
and construction fencing or equivalent, around the staging area(s) and remove the fencing
upon completion of the project. The Contractor shall return all staging area property to its
original condition or better which includes re-grading and re- sodding of disturbed areas.
The County will obtain the USACE, FDEP, FKNMS, and County permits. The
Contractor will be responsible to obtain any other necessary permits not identified by the
Engineer. Use of private homeowner land may require a Temporary Use approval.
The Contractor is required to submit a Construction Methodology Plan (CMP) to Monroe
County, including a Maintenance of Traffic (MOT) Plan (including a truck hauling plan)
for approval prior to initiation of construction. Given the dense layout of the communities
surrounding the project area, the Contractor shall be cognizant of the logistical limitations
of dewatering the dredged material and transporting fill material in the space provided in
the designated staging areas.
Additionally, the Contractor shall be aware of the necessity to take care during the
removal of the sediment so as to not damage the boat lifts present in the canal or any
other privately-owned property. Damage caused by contractor to privately owned
property will be a liability of the Contractor not the engineer or the County.
Florida-EWP Page 2 of 6 April 2019
The Contractor shall be cognizant that the information provided regarding surface
elevations on the construction documents is an approximate estimate, and that even
though the sediment thickness values are a direct observation; no guarantee is made to the
accuracy of the data. Therefore, the contractor shall obtain a pre-bathymetric survey to
compensate for any potential errors or lack of precision in the presented sediment volume
and surface elevation information.
The sequence of Major Activities are as follows:
1) Relocation of recreational vessels (if needed)
2) Inspection of the canal for the presence of T&E species
3) Establishment of the dewatering staging area
4) Mobilization of the mechanical dredge to the project site at high tide
5) Installation of the turbidity barrier at the mouth of the canal
6) Mechanical dredging of sedimentation
7) Discharging of low turbidity effluent back into the canal
8) Disposal of dewatered dredge material
9) Sponsor monitoring firm will confirm that the contractor has dredged to the
prescribed elevations as shown on the plans and specifications
10)Allow settlement of canal water to ensure turbidity at canal mouth does not exceed 0
NTUs above background.
11)Demobilization of dredge
12)Restoration of the dewatering staging area
13)Remove erosion and sediment control measures.
III. MATERIAL TO BE REMOVED
The material to be removed is generally comprised of sand and silt. The Contractor
shall complete physical and chemical analysis on the material prior to construction
commencement to determine the most efficient and economical methodology for the
removal and disposal of the material. The Contractor and Engineer will communicate
on the quantity and location of the sediment to be analyzed to ensure it complies with all
local, state and federal guidelines.
IV. ARTIFICIAL OBSTRUCTIONS
The Contractor shall identify all existing utilities on site before construction
commencement to ensure no impacts. Additionally, the contractor shall identify and
segregate all artificial obstructions within the canals that may impair the dredge
equipment such as vegetative or construction and demolition debris.
V. QUANTITY OF MATERIAL
The Contractor shall independently estimate the sediment quantities to removed based on
the pre-bathymetric survey, plans and the Contractor's independent site investigation of
existing conditions. An initial estimate based on limited bathymetric data is shown in the
Florida-EWP Page 3 of 6 April 2019
plans for each canal, however this figure should be used as guidance only; actual,
estimated volume determination will be the responsibility of the Contractor.
Prior to commencement of the sediment removal, the Contractor shall engage a
licensed surveyor in the State of Florida to provide a 10-foot by 10-foot bathymetric
survey grid of the project area. This will be classified as the pre-bathymetric survey
data obtained by the contractor's surveyor.
The Engineer will review this data and provide the Contractor with a proposed
elevation for dredging limits based on the pre-Irma canal bottom elevations for the
project area. The pre-Irma canal bottom elevations will be used as the controlling
elevation for the specified area approved for sediment removal
The Contractor shall take progress soundings or sweepings to verify compliance with
plans, specifications and work plan. The Sponsor will use this data to verify that the
Contractor does not dig below the pre-Irma canal bottom elevation. Contractor is
responsible for quality control. Sponsor is responsible for quality assurance.
On completion of the sediment removal, the Contractor shall engage a licensed
surveyor in the State of Florida to provide a 10-foot by 10-foot bathymetric survey grid
of the project area using the same locations of the pre-bathymetric survey. This survey
data will be classified as the post-bathymetric survey data obtained by the contractor's
surveyor. The post-bathymetric survey shall be compared to the pre- bathymetric
survey to demonstrate that sediment has been dredged to the pre-Irma canal bottom
elevations as shown on the plans. The Contractor is allowed a +/- 6-inches dredging
tolerance from the pre-Irma canal bottom elevations.
As part of the Quality Assurance process, the quantity of volume removed will be
compared to the pre vs. post bathymetric survey analysis and the calculated field
volume by the monitor utilizing the capacity of the trucks/roll offs and percentage full
of sediment. The volumetric analysis calculation between the pre versus post
bathymetric survey, completed by the Sponsor, will be used as the method of
measurement and payment.
VI. ENVIRONMENTAL PROTECTION REQUIREMENTS
The Contractor shall provide and maintain during the life of the contract, all necessary
environmental protective measures. The Contractor will comply with Federal, State,
and local regulations pertaining to water, air, and noise pollution.
VII. DREDGE EQUIPMENT
The Contractor shall utilize mechanical dredge equipment to remove the sediment. The
Contractor shall be aware that removal rate may be constrained by the sediment
dewatering rate and area and shall implement the appropriate equipment accordingly.
Florida-EWP Page 4 of 6 April2019
The Contractor shall maintain the plant, scows, combings, barges, pipelines, and
associated equipment to meet the requirements of the work. Immediately repair leaks or
breaks along pipelines. Immediately remove dredged material discharged in wetlands
or other areas outside of the identified project area due to leaks and breaks. Removal of
material shall bring the impacted area back to original condition and shall be conducted
at Contractor's expense. Operations shall be immediately halted if a pipeline breaks or
a leak occurs.
Except where authorized in the plans and specifications, dredge pipelines or open
ditches shall not block roads or Rights of Way (ROW) or otherwise interfere with
access unless approved.
VIII. DEWATERING OF EXCAVATED MATERIAL
The Contractor shall implement a passive dewatering system. The passive dewatering
system is dependent on the material consistency. The Contractor shall provide the
Sponsor a dewatering plan for review and approval. It shall be noted that the final
hauling weight of each load (load = sediment + truck + trailer) is not to exceed
Standard Highway Loading rates or a gross weight of 11,000 ton/axle, whichever is
less.
The effluent from the dewatering system will be discharged back into the canal. The
Contractor is required to operate the dredging and dewatering operations such that
mandated permitted turbidity limits are not exceeded. The State turbidity
requirements are 0 NTU increase above background levels in the Florida Outstanding
Waters outside the canal mouth. The Contractor will make any required adjustments to
the operations to ensure compliance with these limits.
The monitor will measure the turbidity throughout the project to ensure compliance
with permits using a Hach 2100Q portable turbidity monitor, or equivalent.
IX. DISPOSAL OF EXCAVATED MATERIAL
The Contractor shall provide for safe and legal transportation and disposal of dredged
materials according to plans, specifications and quality assurance plan. The deposit of
dredged materials in unauthorized places is forbidden. Spoil material inadvertently
spilled on roads,public ROWs and private property shall be promptly removed and the
area restored by the Contractor. The dredged material may not be disposed of under an
unrestricted use scenario. Therefore, the Contractor shall provide their proposed
method of disposal, dependent on the chemical analysis for the dredged material to
Engineer and County for approval.
The tentative final disposal locations are as follows:

licensed surveyor in the State of Florida to provide a 10-foot by 10-foot bathymetric
survey grid of the project area.
Surveys during Progress of Work
1. Preliminary checks of design depth will be determined by soundings or sweepings
taken behind the dredge and barge as the work progresses. The Contractor shall take
progress soundings or sweepings to verify compliance with plans, specifications and
quality assurance plan requirements.
Final Examination and Acceptance:
2. On completion of the sediment removal, the Contractor shall engage a licensed
surveyor in the State of Florida to provide a 10-foot by 10-foot bathymetric survey
grid of the project area. The post-bathymetric survey shall be compared to the pre-
bathymetric survey to demonstrate that sediment has been dredged to the pre-Irma
canal bottom elevations as shown on the plans. To assure excavation to the minimum
depths, the Contractor is allowed a +/- 6-inches dredging tolerance from the pre-Irma
canal bottom elevations so as to not impact hard bottom.
