Hello,
DCM has reviewed the information submitted by the N.C. Department of Transportation(NCDOT) in the
attached cover letter dated March 11, 2022, including the attached contractor letter and schedule requesting
additional moratorium relief for the subject project.
Based upon comments received in response to this request from the N.C. Division of Marine Fisheries, the N.C.
Wildlife Resources Commission and the National Marine Fisheries Service, DCM has determined that the
NCDOT request for an additional 6 days of relief from the in-water work moratorium that is in the CAMA
Permit 70-20 is approved, and does not require additional authorization from DCM beyond this e-mail. Work
must be completed as described, and if any aspect of the project should change,NCDOT must contact DCM to
determine if additional authorization is necessary.
Please note that this e-mail response does not eliminate the need to obtain any additional permits, approvals or
authorizations that may be required. This includes approval, if required, from the U.S. Army Corps of
Engineers and/or the N.C. Division of Water Resources (DWR).
Please let me know if you have any questions or concerns.
Sincerely,

Replacement of Bridge No.29 over Smith Creek on SR 2812(Castle Hayne Rd.)in New Hanover
County; WBS No. 38420.3.3
Dear Mr.Lane,
Please find the enclosed project schedule and request from Civil Works Contracting,LLC,provided
for the purposes of seeking relief from the February 1"to June 30th in-water work moratorium for
the subject project.The contractor is seeking 6 additional days of relief from the in-water work
moratorium,which was required by the Division of Coastal Management in coordination with the
NC Division of Marine Fisheries and NOAA National Marine Fisheries,due to Smith Creek
providing suitable habitat for the federally listed Shortnose and Atlantic Sturgeon.As indicated in
the attached request and schedule submitted by the contractor,the additional 6 days of in-water
work are necessary to twist down four(4)of the six(6)54"caissons for the drill shafts 5-7' deeper
to allow the shaft to be sealed into the hardpan material. A drill rig capable of applying 30,000 lbs.
of down pressure will be used to twist down the caissons. The Division 3 Resident Engineer's
Office has reviewed the request and determined that the proposed timeframe for twisting down the
caissons is appropriate given the existing project status.Once the caissons are at the desired tip
elevation the contractor will be able to resume the necessary pile construction within the caissons
which is not considered in-water work subject to the moratorium. The contractor has indicated that
if this moratorium relief request is not granted,they could suffer mobilizations costs of$57,000
from their drilling subcontractor,Keller.Please let me know if this time-sensitive relief request can
be granted by the appropriate agencies or if any additional information is required.
Sincerely,

Contract# DC00249
Replacement of Bridge No. 29 March 11, 2022
Attention: Alex Stewart
Reference: Request for Fish Moratorium Relief#2
Mr. Stewart,
Civil Works Contracting is currently working on the Drilled Piers of Bridge#29 at Smith Creek
as per awarded NCDOT Contract DC00249. The work on the bridge replacement has run into
some unforeseen difficulties and will need some relief during the fish moratorium that started
on February 1, 2022. Civil Works Contracting is requesting a relief from the fish moratorium for
roughly 6 calendar days to allow CWC and Keller Drilling time to twist the extended 54" casing
shaft down 5 to 7 feet lower to allow the casings to be sealed into the hardpan material.
Civil Works Contracting/Keller Drilling are requesting NCDOT allow us to make some
adjustments to our plan due to the permanent casings not holding the required sealed in the
competent materials. During the pouring of Bent1-C2, the shaft consumed 72 cubic yards
which is well beyond neat line volume. The extra concrete that was placed at B1/C1 appeared
to be pushing soil.This was evident as reflected in the low blow count required to drive the
casing pipe B1/C1 to design tip elevation.
CWC/Keller Drilling also is proposing to twist the extended casings utilizing a CZM EK200
drilling rig capable of applying 30,000 pounds of down pressure (or more) on the casing.The
permanent top casing with a wall thickness of 1/2" and a diameter of 54" will be required to be
twisted 5 to 7 feet beyond the current elevation for sealing the shaft. We propose adding a
minimum of 5' at each casing location. Each casing extension will be welded by a welder that is
currently certified by NCDOT. We estimate that each casing will require at least 12 hours to
weld the extension. Once welded, CWC/Keller will begin twisting the casings until the top of
casing is at the top of concrete design elevation, which should take about eight hours for the
crew at each location. There is a total of 4 locations where the caissons will need to be

extended by welding and twisted down to design elevation at the following locations, B1 C3
and B2-C1, C2, C3.
This moratorium relief request#2 includes the time needed for procuring the additional 54"
caissons, roughly 4-5 days; the time to weld the extension to each caisson, roughly 4-6 days;
and the ti it will take to twist the extended 54" diameter casings to design
4-5 days. WC estimates roughly 41 calendar days for these impacts to our current completion
L date as per the attached schedule. _---
The total number of fish moratorium relief days is estimated to be 6 calendar days or 12 tide
cycles to complete the work in the water. This added time will allow for inclement weather
conditions and unforeseen equipment failures. The following schedule is provided:
• Day 1-5 order and receive the additional 54" caissons, no tide cycles being
affected during this construction phase.
• Day 6-10 prepping and welding the 54" caissons, no tide cycles being affected
during this construction phase.
vA
n • Day 11-15 twist caissons at each location during the hours of 0700 to 1700 with
a low too high to low tide cycle being in affect during this construction This timeline 1
WI stated above will complete the construction for the 54" pipe casing work at bent 1 and
9'‘Z-72. This will complete our waterway disturbance until after the moratorium is cleared on
July 1, 2022.
Should this moratorium relief request be denied, Keller could demobilize from the site at an
additional $57,000 cost, with no guarantees their schedule would allow them to return at the
end of the moratorium in June 2022. The contract could easily overrun the expected quantities
of concrete, with no control of where it flows to. Civil Works Contracting, NCDOT, and the
traveling public for both the r dway and waterway will be impacted for an additional 6
months beyond or contract co pletion date of October 2, 2023, and at an additional cost of
$???
Hopefully, with some partneri by all parties this impact can be avoided.

Stephen, Hannah, and Brad,

The permanent 54" caissons for the drill shafts at B-4590 Smith Creek Bridge do not have an adequate seal at the tip
elevation and need to be twisted an additional 4'-7' beyond the current elevation to sufficiently seal the shaft.This will
not require any vibrating of the permanent caisson.The contractors estimate that it would take approximately 45 to 60
minutes to lower each of the six permanent caissons using the twisting method. Extensions to the caissons would then
be welded to the top of the existing caissons. Please let me know if I need to provide any additional information or if
you think we would need to submit a moratorium relief request for the proposed twisting of the permanent caissons.
