1.02 BACKGROUND

Fort Point stands at the south side of the Golden Gate Strait, forming a substantial landmark at the entrance to San Francisco Bay. Built at the site of an old Spanish gun

RFQ 140P8621Q0068

Section J - Att No. 001 battery, Fort Point was one of the first major U.S. Army installations in the Bay Area. It guarded the San Francisco Bay and Harbor from the Gold Rush-era in the 1850s until

World War II. Although no shots were ever fired in anger from Fort Point, it is the most tangible legacy of the Civil War in California, and represents California’s little known, yet significant, political and social involvement in the Civil War. Built to hold four tiers of cannons, the fort is also an outstanding example of masonry fort construction and is the only fort of its style on the West Coast of the United States. As a testimonial to the fort’s historic significance, the southern anchorage of the Golden Gate Bridge was designed to gracefully arch over it.

Fort Point became a National Historic Site in 1970 and is today managed as a district park unit within the larger Golden Gate National Recreation Area. The fort’s scenic location under the south end of the Golden Gate Bridge attracts visitors throughout the year, many of whom accidentally happen on the fort and have no idea of its significance.

Over 300,000 people visited Fort Point in 2017, with a significant number of those being international and national vacationers, particularly during the summer months.

The Fort Point National Historic Site is listed in National Historic Register and owned by the Department of Interior, National Park Service, herein after called NPS, and is maintained by the Golden Gate National Recreation Area (GOGA).

1.05 SCOPE OF WORK

In early September:

1. Remove 2 each reproduction 10” Columbiad cannon barrels from existing wood framed gun carriages and place them on wood blocking on the Parade Ground to be painted

(painting by Others). Cannon will be placed near the west edge of the Parade Ground, near their current locations. These 2 cannons are in the 10,000 lbs. weight range each, measure 37” side to side (to the outside of the pivot trunnions) and are app. 130” long.

2. Move the 2 wooden carriages from under the 2 Columbiad cannon and into a dumpster

(provided by Government) staged outside the Fort.

3. Move 1 each historic 10” Rodman gun barrel from existing wooden blocking in

Casemate #19 just off the Parade Ground next to 2 Columbiad cannon for painting

(painting by others). Reuse existing wooden blocking. The Rodman gun barrel may weigh as much as 15,000 lbs., measures 38” in width (to the outside of the pivot trunnions) and is 138” long.

4. Move the historic cast bronze San Martin cannon from it’s existing wooden carriage and onto wood blocking for safe storage. The San Martin barrel is to be both blanket wrapped and sealed in plastic prior to the move for protection of the patina. The San Martin is smaller and lighter at app. 5,500 lbs., 22” wide (to the outside of the pivot trunnions) and

110” long.

Scheduled in conjunction with the exhibit installation process:

1. Place 1 of the Columbiad cannon barrels onto new custom-made steel mount (mount by Others) in Casemate 1.

2. Place the Rodman gun onto new custom-made steel mount (mount by Others) in

Casemate 3.

3. Place the San Martin cannon inside Powder Magazine 1onto it’s refurbished wood carriage (refurbishment by Others). Access to Powder Magazine 1 is restrictive- the hallway entrance to narrow and the corners too tight for the San Martin to pass through unless the barrel traveled tipped up on end. It is projected that it would be easier to hoist the cannon through and existing window from the Parade Ground. The wood planked floor will have already been reinforced at the interior location where the cannon is to be placed (reinforcing by Others), but will require additional temporary planking or plywood to spread the weight load of the cannon while moving from the interior of the window over and on to the permanent gun carriage.

4. Place the 2nd Columbiad onto existing wooden blocking on display in the location in

Casemate #19 where the Rodman had been.

1.06 GOVERNMENT SUPPLIED MATERIALS

The Government will provide wooden blocking for the temporary storage of the cannons on the

Parade Ground. Government staff will remove and replace the wooden boardwalk for access to the slightly raised Casemate area to prevent it from damage by Contractor’s equipment.

Government staff will remove and replace window panes from the Powder Magazine 1 window for access through.
