The Weitzel column is shorter by 3-‐1/4”.

This was found in a mathematical error on the height of stone #W31.

The original Architectural Report from the listed the stone drum at a height of 48-‐3/4”.

Forensics confirmed the #W31 actually measures 45-‐1/2” in height.

Image of the War Department Building before it was dismantled and removed to Arlington

National Cemetery.

Image:

Date Unknown.

The six (6) stone columns and entablature were repurposed into two entrance gates.

One containing two (2) freestanding stone columns crowned with beautiful limestone Urns known as the

ORD-‐WEITZEL

GATE.

The other gate consisting of the four (4) remaining stone columns crowned with an ornate entablature.

It became famously known to honor General

SHERIDAN

GATE

among other Generals of the Civil War.

The gates were constructed in 1879.

Two of the stone columns used from the War Department Building from the previous image.

The gate was constructed in 1879.

The date of this image is unknown however it was sometime after when the Generals names were engraved into the stone columns.

This image of Ord-‐Weitzel

Gate shows a lime wash finish as it appeared in the early twentieth century.

It appears from this image that the capitals, pedestals and Urns were not lime washed at the time of this photo.

Note:

The drawings in this report are organized in sequential order of assembly, starting with

General Ord’s Column followed by General Weitzel’s Column.

The drawings are laid out in order from the stylobates to the Urns.

Additional Note:

If a historic stone component is not listed within these drawings it indicates no repairs were necessary.

REPAIR

#33A:

The Stylobate base block required careful removal of a previous cement repair.

The parent Aquia Creek Sandstone was prepared to receive a

Dutchman repair that was harvested from the same Aquia Creek Sandstone from the Weitzel

Column Drum #W44.

The

SPC

stone carver returned the original stone chisel marks as would have been originally found in the finished repair.

The opening shown below the Dutchman represented in red is the original slot that was cut from the historic stone in order to receive the iron gates that once were part of the entrance to the cemetery.

REPAIR

#34B:

A significant amount of original Aquia Creek

Sandstone was damaged in this Column Base.

The red indicates the size of the Dutchman repair.

SPC

obtained a selected structurally sound piece of harvested stone for this repair due to the consideration of the proximity to the structural loads it may endure in its position within the column.

This piece required the

SPC

masons to reposition the stone and turn it over in order to make the necessary Dutchman repairs.

The stone was significantly damaged from previous deconstruction efforts.

As indicated by the red colors a substantial amount of stone was lost during the life of this particular piece.

DRUM

(TOP)

#37:

Stone column drum W was by far the most difficult historic stone to repair.

The significance of the amount of material which was lost required

SPC

stone carvers to come up with a strategy to create a well-‐bonded mechanical key without the use of metal anchors of epoxy or bonding agents other than lime putty.

The use of a Dutchman

European key was used to secure the Dutchman to the parent stone.

The technique used a geometric shape in combination with a dovetail box-‐cut into the stone creating an invisible joint.

CAPITALS

#102 and #103:

The stone capitols proved to be the most difficult aspect of the project.

Removing the paint from the stone intricacies was most taxing.

We stabilized the loose pieces, filled cracks and holes, re-‐carved small areas.

SPC

used the ring test to determine the stability of the historic stone.

We are pleased with the results in comparison to what we started with and in comparison to the four that remain for Sheridan.
