A
construction project this summer at Fort Fisher State Historic Site in North
Carolina is something you don’t see every day – or will likely see anywhere
else.
Sections of
precast concrete were placed Friday near a giant mound of dirt as crews begin
to build a replica bombproof -- an earth- and timber-covered structure that protected a garrison from shelling.
The Civil War
site near Kure Beach and contractors are engaged in an extraordinary effort to
recreate three traverses, bombproofs, a magazine and a sally port that were
vital parts of the Confederate fort, which fell in furious hand-to-hand combat in
January 1865.
“This is a one-of-a-kind project,” said Ben Warren
project manager with Bordeaux Construction of Morrisville, N.C. “We build much
larger projects, but many things on this project are unique.”

A portion of
the vital fort’s earthworks was leveled during
World War II to make way for an airstrip when the area was used to train anti-aircraft and coastal artillery units. The work is in
conjunction with a new visitor center, also being built by Bordeaux
Construction.
The earthworks project requires nearly three dozen pieces of precast concrete.
About half have arrived, said Warren. The pieces were made by the Alcrete plant
in Jacksonville, N.C.
Chad Jefferds, assistant site manager at Fort Fisher, told the Picket there will be a new tunnel allowing visitors to
pass through the fort at the center sally port, as would have been the case
originally, along with bombproofs under the traverses.
The traverses are being built in the same line as those that have withstood the effects of
time and change. Rebuilding the fort will
involve the reconstruction of the 7th, 8th, and 9th traverses.

“You will not see the
precast concrete tunnels, as they will be clad in wood, such that the tunnels
will appear as though they were built from timber, same as they were built
originally,” Warren said in an email.
Jefferds said
the concrete will be placed, waterproofed and buried over the next several
weeks “so that work can begin on the gun emplacements atop the
recreated mounds. The current timeline for the work has everything being
completed by early September, but this is all highly dependent on weather.”
The site, with the exception of a tour stop, closed in
April. The new 20,000 square-foot visitor center, a significant upgrade, is just north of the east-west line
mounds of earth known as traverses that were part of the defenses. Much of
the eastern part of the fort has been claimed by the ocean.

Crews will work to ensure
any exposed portions of the concrete will be made to look like they appeared
during the battle.“Visitors will be able to walk through the tunnel and bombproofs, as well as up into the gun emplacements themselves,” said Jefferds.
“We are in the process of sourcing reproduction munitions, boxes, barrels, etc. to make the bombproofs appear as they may have during the Civil War.”
With the three traverses will come two gun emplacements, which will have a heavy cannon in each, along with two 12-pounder Napoleons in the center sally port.
The project will allow people to interact with the fort in a whole new way, as the tunnels and bombproofs have been caved in and inaccessible since the late 19th century, said Jefferds.

The design of the recreated earthworks is based on historic maps, photographs and descriptions. Architectural and engineering firm Clark Nexsen made the designs, which will be similar to the original mounds, said Warren.Dennis Stallings, design director for Clark Nexsen, said it had an
archaeological consultant on its team, Commonwealth Heritage Group, which “provided
documentary research along with archeological research and provided a
comprehensive report on the original fort and its construction."
There were archeological investigations in 1970 and another in 1981 that
provided context.
“We aimed to create earthworks that appeared historically accurate while
seamlessly incorporating modern construction techniques,” Stallings wrote in an
email. “This endeavor presented a unique challenge, as we found little
precedent to guide us.”
“The reward is a project that is immensely satisfying as architects. It
is a one-of-a-kind endeavor that millions of people will interact with over the
coming decades,” he said.

Fort Fisher was built on the peninsula between the Cape Fear
River and the Atlantic Ocean, south of Wilmington.
On Jan. 15, 1865, after a naval bombardment, the Federal army attacked
from the western, river side while Marines pushed in from the northeast
bastion. The fall of the “Gibraltar
of the South” cut off blockade runners and the
last supply line through Wilmington to Robert E. Lee’s Army of Northern
Virginia. U.S. Colored Troops were among those taking part in the attack.
Essentially everything between Shepherd’s Battery on the
western end of the fort’s land face and the center sally port were the scenes
of intense fighting during the US Army’s assault. The fighting went from along
the traverses from west to east and was often hand-to-hand.
Jefferds said planning is underway for a grand opening ceremony, which
should take place toward the end of September “if everything stays on schedule.”

The new museum will be three times larger than the current one, with more room for groups, educational space, rental opportunities, staff offices, etc. The exhibit area is also larger and will be based on the experiences of the place by the people who lived, fought, and died here.While Fort Fisher is still the focus, the approach in developing our exhibits was much more driven by people, including underrepresented groups, said Jefferds.
“The (visitor center) exhibit casework and artifact installation will begin next week and will wrap up on the last week of August, at which time the only remaining work will be on the earthworks and fortifications,” said Warren.
The old visitor center has been torn down.
"Doing so
allows us to create a better viewshed of the fort from the new visitor center
as well as create green space for programming," said Jefferds.
