OBJECTIVE: To award Sid No. 11-5633 to Southwind Construction Corporation for
the Maintenance Dredging for Wiggins Pass for a not to exceed contract total of
$750,000.
CONSIDERATIONS: This scope of work is for Wiggins Pass Maintenance Dredging.
This will include the contractor mobilization and demobilization; dredging and sand

monitoring; construction surveys and sand analysis. The negotiated bid is broken down
as follows:
Sid Item 1 - Mobilization and demobilization
Bid Item 2 - Dredging and sand discharge
Sid Item 3 - Turbidity and environmental monitoring
Sid Item 4 - Construction surveys
Sid Item 5 - Sand analysis
$ 442,240.00
$ 257,448.50
$ 15,053.00
$ 32,893.50
$ 2,365.00
TOTAL Price Not to Exceed .............................................................. $ 750,000.00
The bid was publicly advertised on December 3,2010. Email notices were sent to 1212
firms with 93 vendors requesting full packages. On December 15, 2010 the Pre-Bid
conference was held, 8 vendors were present. The bid opening was held on January 5,
2011 where 6 vendors responded and their bid packets were opened. The budget
established for this work is $750,000. The bids were reviewed and tabulated as follows:
Paul Howard Construction Company, Inc - $655,960.00
Southwind Construction Corporation - $836,092.10
Orion Dredging Services - $999.665.66
Jahna Dredging, Inc - $1,284,854.00
Florida Dredge and Dock, LLC - Non-Responsive
Associated Marine Contractors, LLC - Non-Responsive
Subsequent evaluation concluded that Paul Howard Construction Company did not
meet the 14 inch dredge specifications and lacked the experience of "dredging in
exposed areas similar to an ebb shoal channel" as identified in the technical
specifications.
None of the bids from the qualified and responsive bidders were within the appropriated
budget for the project. In accordance with Section VI.D of the Soard's purchasing
policy, staff has negotiated price reductions to the contract of $86,092.10, resulting in a

Wiggins Pass Maintenance Dredging, Bid No. 11-5633
.
Gary
I recommend Southwind Construction be selected for the project based on the discussion below:
The low bidders were unresponsive, in failing to turn in the questionnaire with their bid, which was
critical to an accurate evaluation. This is based on purchasing decision.
In evaluation of Paul Howard Construction, I called Steve Miller from Ellicott Dredge, and he said the
size of dredge is determined by it inside diameter at the discharge flange. This is confirmed by Don
Searles, who has a web site where he states the same thing (see blue highlight below). Based on size of
dredge, Paul Howard Construction does not meet the criteria in the specification.
'"
The second reason that Paul Howard is not qualified, is his lack of experience in open oce;:~n/gulf
dredging. All his known projects are within estuaries or bays. The Philadelphia District US'AcE (Monica
Chasten and Jerry Jones) says Paul Howard Construction works hard and learns quickly, but the work did
not meet the requirement of paragraph 1.4 on page TS-3 of the technical speciation. The New York
District Corps of Engineers called me back on Paul Howards job in New York. There performance was
lacking in mobilization (to slow), daily reports and general responsiveness, and starting a modification
before a notice to proceed. In the end, the physical work was completed in an acceptable manner, but
it was hard working with Paul Howards superintendent.
I called Lee County (Robert Neal) and the Jacksonville District (Jesse Mancini and Mike Lyons) and they
all rated Southwind Construction as satisfactory to above average and capable of performing work in the
ebb shoal channel. Michael Poff (cEC) provide a positive recommendation by E-mail. Southwind
Construction dredge has a 14" discharge, and therefore they qualify per paragraph 1.4 on page TS-3 of
the technical speciation.
.
Based on the criteria in the specification and the lowest responsive bid, I recommend Southwind
Construction be awarded the contract.

~1~~b~ig~--f~ijg~j?I'l_t5~~~~j-~ag~:p~Dip'd Dredges come in sizes from 8 inch [203mm] to 36
inch [914mm]. An 8 inch [203mm] dredge will typically pump 2,500 gpm [gallons per
minute] [9,464 (pm] with an engine horsepower of around 300 [223 kw] and a weight of 25
tons. A 36 inch dredge [914 mm] will pump up to 70,000 gpm [265 cmm] with up to
10,000 horsepower [7,456 kw] and a weight of several thousand tons. With a given size
dredge the production can vary widely and is determined by the outside diameter of the
impeller in the dredge pump, the speed of the impeller, the horsepower of the engine
driving the dredge pump, and the friction and static head losses in the pipeline.
