Construction of
the Pedestal
Richard M. Hunt, architect of the
pedestal.

IN 1877, Congress authorized the setting aside of
ground in New York Harbor on which to erect the statue and made
provision for its reception and maintenance. Gen. W. T. Sherman was
designated to select the site. In accordance with Bartholdi's wish, he
chose Bedloe's Island.
Gen. Charles P. Stone, an Army engineer, was
appointed engineer in chief by the American Committee. It was decided
that the pedestal should be built in the center of old Fort Wood, an
11-pointed star-shaped fort constructed early in the nineteenth century
to protect New York which was becoming increasingly important as a
commercial depot. Ground was broken for the foundation on April 18,
1883. Excavations were more difficult than anticipated, because of the
heavy masses of stone masonry and concrete encountered in the cisterns
and old arches designed as bombproof and not all indicated in drawings
of the fort. Placing of the pedestal foundation, almost solid concrete,
at a depth of 20 feet in the center of the 11-pointed star-shaped walls
of Fort Wood improved its stability.
Because of the decision to build the pedestal upon
the old fort, the design recommended by Bartholdi had to be changed, in
the interest of architectural harmony, strength, and economy. Granite
from Leete's Island, Conn., was selected as the material for the outer
wall, to be backed by a massive shaft of concrete. The cornerstone of
the pedestal was laid by William A. Brodie, Grand Master of the Grand
Lodge of New York State, with impressive Masonic ceremony on August 5,
1884.
Work on the pedestal progressed rapidly until the
fall of 1884 when with only 15 feet of the structure completed, work had
to be stopped, as the American Committee was reaching the end of its
financial resources. With the solving of the financial problem in 1885,
work was resumed the builders then turning their attention to a highly
important engineering problemhow the statue would resist wind
pressure.
Pedestal completed on April 22,
1886.

When the 29-foot level was reached in construction of
the pedestal, four huge girders were built into the walls so that they
formed a square across the inside. Fifty-five feet highera few
feet from the top of the pedestalsimilar girders were placed, and
the two sets were connected by the iron tie beams which continued on up
and became part of the framework of the statue itself. Thus the statue
was made an integral part of the pedestal, and any force exerted upon it
was carried down to the 29-foot level, so that the great weight of the
upper 60 feet of the granite and concrete pedestal was added to that of
the statue.
The pedestal itself is considered one of the heaviest
pieces of masonry ever built. It towers 89 feet above its foundation and
is so anchored to itand that in turn to the rock below the
foundationthat a wind storm to overturn the statue, would almost
have to invert the whole island. General Stone evolved the method of
anchorage, and his careful calculations have been proved by the test of
years.
On April 22, 1886, the last stone of the pedestal was
swung into place and the jubilant workmen showered into the mortar a
collection of silver coins from their own pockets.
Now the stage was set to receive and place in
position the generous gift from the people of France.
