There are four sections in the fence surrounding the Old Navy Hospital

INVENTORY METHODS AND PROCEURES

During April and May, 2000, the Friends of the Old Navy Hospital conducted a detailed inventory of the fence surrounding the Hospital in order to establish a baseline documenting the condition of this fence.

After the major components of the fence were identified, and a numbering scheme established, volunteers counted each part, and the counts were verified by other volunteers.

NUMBERING SCHEME:

SECTION NUMBERING: The numbering scheme starts at the far left (facing the fence from the outside) of each section. For example, along the North Section (Pennsylvania Avenue SE) the fence section nearest the corner of Pennsylvania Avenue SE and 10^th Street SE is numbered North 01 (N01).

PART NUMBERING: Within each section, parts are numbered from the left to right (again facing the fence from the outside), and from the top to bottom. For example, each vertical bar is topped by a spear point (labeled in the count "vertical bar cap"). The one at the farthest left is "VBC01". The next one to the right is VBC02, and so on.

NUMBERING SCHEME: The fence was first broken down by the four sides: North Side (Pennsylvania Avenue SE); West Side (Ninth Street SE); South Side (E Street SE); and East Side (Tenth Street SE).

Each side was then broken down by fence section. The typical section consists of four vertical bars that hold all of the other components in place, and also anchor the section by sliding into insets in large upright dividers between each section.

The fence itself is anchored by four corner posts, which are identical to six gate posts along the West and South side.

Section	Street	Corner Posts	Gate Posts	Fence Sections
North	Pennsylvania Avenue SE	1		39¹
West	9^th Street SE	1	2	22
South	E Street SE	1	4	31
East	10^th Street SE	1		11²
TOTAL		4	6	103

NOTE 1: It appears possible that the original fence did not have an entry from Pennsylvania Avenue SE, and that the current opening (Section N17) may well have originally been a fence section removed if the concrete stairs were later added. This opening is the same length as the standard section, and there are no visible signs of footings for gateposts. This supposition cannot be confirmed without the original plan, which is not currently available.

NOTE 2: One of the two sections missing along 10^th Street SE (Section E09) is much shorter than the standard fence section, and may well have been a stair opening in the original fence. This supposition cannot be confirmed without the original plan, which is not currently available.

SPECIAL NOTE: Fence section West 04 was recently "repaired" by cutting the horizontal bars and welding them to brackets that were in turn welded to the section divider uprights. Since this section was most unfortunately installed backwards, the count was done from the inside of the fence facing out in order to preserve the standard numbering scheme.

SECTION DIVIDER UPRIGHTS: Although not a part of fence sections, in the inventory these are (arbitrarily) counted with the fence section to the immediate right of the divider upright (looking from the outside) in order to account for them and to locate their place in the fence.

GATES, OPENINGS AND MISSING SECTIONS: These were also designated with a sequential section number in order to establish their specific location in the fence.

RIVETS AND WASHERS: The number of rivets and washers in each horizontal bar were counted in order to learn the number that will need to be replaced in any restoration of the fence. However, the current count is listed as zero for these parts due to their advanced corrosion (many rivets have burst), and the need to dismantle the fence in order to remove rust inside the parts. Since the rivets were inserted through washers from the outside bar and flanged on the inside, they will need to be drilled out and replaced under any restoration effort adopted.

NOTES:

Parts that are broken are noted with a "B" in the count in order to note their specific position in the fence, but not counted in the sum of parts because they cannot be considered available for use in restoring the fence.

Parts that are covered by concrete in what is presumed to be an earlier "repair" of errosion damage are marked with "NV" for "Not Visible".

Some compass circles are not complete in order to compensate for a reduced section width. If the reduction was close to half of the circle, then it was noted on the inventory with "H" (for half).
