and technical specifications for obtaining Notice to Proceed from the State:and federal agencies 1
to move forward: It is intended that the bidding and construction phase for the South Marco
Beach Restoration project will be combined With the Water Turkey Bay channel dredging project
for cost Savings. The Water Turkey Bay project involves nearshore sediment disposal and may
be conducted during the;!atter portion of 00'2010 sea-tattle;nesting season. Upon completion
and demobilization, the selected Contractor may then mobilize to the South Marco Beach
Restoration project site at the south end of Marco island to complete.thit work after November
1, 2019 and prior to April 15; 2020 remaining outside the sea turtle-nesting seasbn. Combining • ,
these projects-with one -elected-Contractor should result in reduced Contractor mobilizatiOn-,

• Dear Mr.Flething,
, .
This•document is intended to serve as a technical 'cost proposal for the abovementioned
' , . sediment sampling effort This proposal is based On correspondence between fitunistOri&
Moore Engineers(H44)and Athena Technologies,Inc.during April and May of 2019.
. .
It our Understanding that you Will require the collection of 8 geotechnical vibracore samples .-
toa depth of 15 feet below Sethi/lel-A.641.We from an area Within Caxambas Pass at Marco
Island;.Plorida. -It is our :iiiiddittanding- that existing sediment surface elevations range
. ,
between=10 to-15.feet in relation to the North American Vertical Datum of 1088(NAVD88)
and that project depth for this effort is-21 feet in relation to NAVD88. Athena will then be
responsible for producing a geotechnical report that includes geologiclogs, vibracore'
photoinosaicse and geotechnical data: .
. •
. .
.. ,
Athena will utilize out 35-foot research vessel,Artemis, to operate as the vibracore sampling
platform for this effort. Arteinis is equipped with all required U.S.Coast Guard(USCG)safety .
gear arid will be operated by a USCG certified Captain. The captain will be actOmpanied by
three additional creWrnernbers, Athena will utilize a Trimble Differential Global Positioning
System: (tub-Meter. accurate) interfaced with HYPACK for horizontal positioning, and a '
Furuno fathometer (Verified by lead line) for gathering water,depths. Athena will utilize a
. '
Champion TKO Global Navigation Satellite.System(accurate to+/-2 centimeters) interfaced
with the Florida, Permanent Reference Network (FPRN) to deterinine, sediment surface
elevations and final hoiizontarcoordinates.
• .
. .
During sampling operations,Artemis will beniatieuvered to the desired sample iodation using I
coordinates provided by H4M. Once on station,the Vette'will be immobilized using a triple
point anchor sytterri. When the vessel is anchored,the coordinates at the vessel's location will
be. checked against the desired sample coordinates to ensure accurate vessel placement •
, : • Athena's custom-designed and fabridated vibracore system will then be deployed from the

penetrate until it reaches the required target depth of 15 feet:below sediment surface, or
refusal: The sample barrel is then retrieved using an electric winch. Once the sample is on 1
, .
deck,the core is measured,cut,capped,and labeled.
. - .
If vibtacore recovery is less than 80%,or if refusal"is met and the material at the base of the
coreis not limestone, carbonate cemented clastic sediments, or 'indurated silt/clay, then
Athena Will,make 1 additional vibracore attempt to reach the required penetration depth

the cores(in accordance with ASTM U2488)at this facility: Draft core logs will be sent
R&M to allow for selection of sub-sample intervals. Upon receipt-of sample intervals ,
frbin1.-f&M;Athena will extract and ship the sub-samples to Terracon Consultants,Inc. ,
(Terracon)in Jacksonville,Florida for analysia. _drain size analysis will be'Conducted •
,In accordance with procedures outlined in ASTM D6913, using the following sieves: .
3/4", 5/8", 7/16"; 5/16", 35„4, 5; 7, 10, 14,:18; 25, 35, 45, 60, 80; 120, 170, 200, and 230. 1 '
, •
Visual estimation of shell content will be conducted on material retained in each sieve
using ,the TefrY, and Chilingar (1059) Method. ,Sub-samples will be classified in ,
accordance with guidelines outlined in ASTM 132487. Carbonate analysis will be
• -
conducted in accordance with the Twenhofel and Tyler add digestion method(1041). . .
Athena will compile logs and grain size data,in gINT format. :Grain size analysia will'
, be"performed On the carbonate sample before and after acid digestion. The final data
report Will include a methodology overview,vibracore location data,core logs,photo.-
__ ..
rriosak core images, and grain size data. Prior to submittal, the final:data:report will
be reviewed by Dr. Walter Sexton, a professional'Geologist registered in the state -
. .
Florida. The final deliverable will include the:following:1.a formal report in PDF
' •
format;the gINT project file,and raw grain size data in-excel format. .

It'should be emphasized that: crew and vessel safety is of utmost concern when
working adjacent to or on top of nearshore shoal complexes associated with inlets. In
shoal-type settings, wave action is increased due to amplification and wave angles
•
converge(due to refraction) as they approach the shoal,.which can create.potentially ,
1
hazardous situations. Athena will make every reasonable attempt to collect the 1

vibracore samples from the requested Iodations;however,the vesselcaptain will have
.
sole discretion to abandon,or choose hot to attempt,core collection or jetting in certain
areas if crew and vessel safety are threatened due to site conditions. If a location is
