Bobcat Skid Steer Loader - Building Demolition

A skid steer do not have a driving wheel and orientable wheels like cars.­ In order to turn (i.­e.­ steer), the driver uses levers to change the rotation speed of the two wheels on one side vs the other side, causing it to skid.­ By having the wheels on one side turning in one direction and the other side in the other direction, a skid steer can turn on the spot.­ Skid steers use the same technique as tanks or crawlers excavators, except that they use wheels rather than tracks.­ This technique allows for a much simpler and more robust drive train and increase maneuverability, but does not allow driving it at high speed and it only works well when the front and back wheels are close, i.­e.­ on very short wheels base vehicles.­

This development project is called Presidio PHSH Adaptive Reuse Housing.

The Public Health Service Hospital (PHSH) is located in the Presidio of San Francisco.­ It has been rehabilitated into luxury condos housing in 2010, and it is now called "Presidio Landmark Apartments".­

The abandoned Public Health Service Hospital (PHSH) is located in the Presidio of San Francisco, at the north end of 15th av (see aerial photo, historical map, google-map, google earth Placemark, and bird's eye view).­ Built in 1931 on the site of the old U.­S.­ Marine Hospital (1875), the 480-bed hospital, also known as building 1801, closed in 1981.­

From 1981 to 1988 the hospital was used by the Defense Language Institute (DLI), except for the 6th floor southwest which was used by the now defunct Letterman Army Medical Center (LAMC) for medical research and animal experiments.­

The PHSH was completely abandoned from 1988 to 2009.­ The modern wings have been demolished in 2009 and and the main historical buildings have been transformed into housing in 2010, so all the graffiti you see here has been destroyed.­ See Presidio PHSH Adaptive Reuse Housing - The rehabilitation project for the PHSH, and the now finished project, called The Presidio Landmark .

The Presidio Hospital was really interesting place to explore, as it is very large (6 interconnected buildings, most of them 7-story), mostly intact and covered with *many* cool graffiti. It was once used as a movie set (see those Command Center Delta stencils).­ At night the place is rather spooky. We heard that one person got murdered in the PHSH in 2002.­

The building in the back contains the hospital kitchen with its enormous freezers, the operating rooms and a number of X-ray machines.­ Many operating rooms still have floodlights and rubber tubes hanging from the ceiling. Several old X-Ray machines are rusting in place.­ Many of those X-ray machines and scanners were top-of-the-line multi-million dollar equipment in 1981 when the hoptital was closed, and they have just been left there, what a waste of public money!

In the eastern part of the basement, the morgue with six big drawers for the dead bodies, and the greenish autopsy room next door.­ Many rusted machines, pumps, pipes and tanks are still there.­

The buildings are fenced and boarded and since 2006 it appears to be guarded 24/­7.­ Police are often seen in the parking lot.­ Cleaning crews may be working in the buildings during working hours.­

There is now an alarm (with infrared heat sensors) in the main stairway area and in the basement, and it notifies the U.­S.­ Park Police when it triggers (it also makes quite a lot of noise!).­ Officer Pat Smith may send his dog after you and call his colleagues for backup.­ Remember, trespassing is illegal and can be prosecuted (if you get caught!).­ See California Penal Code 602 (k).

If the Park Police sees you going in or out of the PHSH, you are likely get arrested and to receive a $100 ticket.­ Recently Park Police confiscated Memory Cards from the digital cameras of trespassers, which I don't think they have the right to do.­

And if you intend to do graffiti or cause any depredation, you should read 18 U.­S.­C.­ § 1361. I wonder if the Presidio Trust could get in trouble for destroying all this unique graffiti art when the buildings will be rehabilitated..­.­ Hmmm I guess not: Graffiti is detrimental to the health, safety and welfare of the community according to the San Francisco Board of Supervisors.­

Another interesting area a few yards North is the old SF-89L Nike ground-to-air missile site from the cold war era, but that's another story!

Those photos were taken in december 2004, january, february, march and july 2005, may and December 2008.­

Camera used: Sony A700 DSLR and Sony DSC F828 (8 Mega-pixel).­

A big thanks to Luiza Leite for telling me about this place!
