SCOPE OF WORK WIGGINS PASS INTERIM DREDGING
CONTRACT 15-6382
MAY 3,2019
The following is a scope of services for engineering, permitting, and construction phase services
for the proposed 2019/2020 interim maintenance dredging of a portion of the Wiggins Pass
Navigation Channel. In all cases herein, County refers to Collier County, Park refers to Delnor
Wiggins State Park, DEP refers to Department of Environmental Protection, USACE refers to the
U.S. Army Corps of Engineers, and Engineer refers to Humiston & Moore Engineers. The
estimated duration is 365 days. Construction bidding is to be combined with Water Turkey Bay
dredging for cost savings.
Background:State and federal permits are in place at this time for ongoing maintenance dredging
of Wiggins Pass. Construction plans for interim dredging will be based on the most recent
available data from monitoring and post construction surveys at Wiggins Pass and the adjacent
beach area. With the planning of the maintenance dredging of Water Turkey Bay Channel for
2019, an opportunity is established for combining this work at Wiggins Pass and share the
mobilization costs. Shoaling has occurred in the channel and dredging of that sand can be placed
in the north nearshore disposal area being used for Water Turkey Bay Channel dredging.
There also exists an accreted sand spit on the south shoreline of the inlet with opportunity to
excavate and place that sand in the adjacent areas in need of sand below Mean High Water along
the Park beach and inlet shoreline. Any necessary permit modification to the Wiggins Pass
Maintenance Dredging permits to accomplish this task can be included with the state request for
the Water Turkey Bay project. It is intended that the bidding and construction phase for the
Wiggins Pass Interim Dredging project will be combined with the Water Turkey Bay Channel
dredging project and South Marco Beach Restoration. The Water Turkey Bay project involves
nearshore sediment disposal and may be conducted during the latter portion of the 2019 sea
turtle nesting season. Upon completion of the work at the Water Turkey Bay Channel, the
pipeline will be in place for disposal the north nearshore disposal area for the work at Wiggins
Pass. Upon completion of this work, the selected Contractor may then mobilize to the South
Marco Beach Restoration project site at the south end of Marco Island for completion of that
work outside the sea turtle nesting season after November 1, 2019 and prior to April 15, 2020.
Combining these projects with one selected Contractor should result in reduced Contractor
mobilization costs than if constructed separately by different contractors. Additionally,costs for
Engineering Services during the bid phase and pre-construction phase services when provided
for the combined projects will result in cost savings to the County. Services provided by H&M will
be Time and Materials.

Engineering,Permitting,and Construction Phase Services
Prepared by Humiston&Moore Engineers 5-03-2019
Task 1:Plans, Regulatory Coordination and Preparation of Technical Specifications, Bid
Schedule and Opinion of Probable Costs
Construction Plans and Agency Coordination: Engineer shall prepare updated construction plans
and specifications for the interim dredging at Wiggins Pass based on available and any updated
bathymetric and topographic data from the County. Pre and post construction surveys will be
required by the Contractor prior to construction. Areas designated for dredging and
redistribution are highlighted on the attached figure with this Scope of Work.
Upon completion of the plans and acceptance by the County, Engineer will coordinate with
County and Park staff and meet with state and federal agencies to initiate review. Following pre-
application meetings, plans will be filed with both the State DEP and USACE for processing.
Technical Specifications, Bid Schedule: Based on feedback from state and federal agencies,
Engineer will prepare Technical Specifications and a bid schedule to be included with the county
contract documents for bidding. Engineer will review permits for any additional clarity required
in Technical Specifications for consideration of qualifications and multiple project coordination
for bidding with County staff. It is expected that dredging within the navigation channel is to be
done with a hydraulic dredge while redistribution of sand on the south shoreline at the Park may
be conducted mechanically. As noted above, it is expected that this set of specifications will be
coordinated with the Water Turkey Bay dredging project located just south of this project area
east of the Park in north Collier County as a combined bid package. Technical specifications will
require the selected Contractor to complete pre and post dredging and beach construction
surveys.
Opinion of Probable Costs(OPC).: Prepare a final opinion of probable construction costs based on
the final design. This will include potential cost savings from combining this project with the
Water Turkey Bay project. Development of opinion of probable construction costs will include
review of county records for dredging at Wiggins Pass and recent costs for similar construction.
Engineer will forward the final Opinion of Probable Costs with final construction plans and
technical specifications to county for bid purposes.
Deliverable: Plans,Technical Specifications, and OPC. Task 1 (TM) $21,726
Task 2 Bid Phase Services
Pre-Bid Conference, Technical Support and Addenda to Bid Package: Engineer will coordinate
with County staff in preparation of responses to inquiries from potential bidders and attend a
pre-bid conference with representatives of county and prospective bidders and suppliers for this
project combined with Water Turkey Bay Dredging and South Marco Beach Restoration.Engineer
will prepare addenda to bid documents and responses to requests for information from

ensure no redundancy in services for reduced costs.
Deliverable: Bid recommendation. Task 2(TM)$2,300
Task 3 Pre-Construction Services
Pre-Construction Regulatory Requirements and Agency Meeting: Engineer will coordinate with
Contractor and County staff in ensuring sufficiency of required items in Technical Specifications
for fulfillment of pre-construction state and federal regulatory requirements for issuance of a
Notice to Proceed. Engineer and County staff will conduct a pre-construction meeting with the
state and federal agencies and their respective resource agencies to present the combined
projects, intended performance, understanding of permit requirements, and schedule. The
selected contractor will be present for this meeting. Engineer will provide required notices of
commencement to respective state and federal agencies.
Pre-construction phase services provided when combining projects for bidding will be further
adjusted, if needed, to ensure no redundancy in services which will result in lower costs.
