Summer 2006
Project Background: The San Francisco Fire Department's Training Academy was in need of a renovation on their training tower, an eight story high rise that the department uses for training in the use of ladders and urban fire fighting techniques. The existing tower, constructed in the 1950's was built of tilt-up concrete and finished with brick veneer. Over the years, water was intruding under the brick veneer and bricks where falling from extreme heights; forcing the city to condemn the structure and rendering the building useless for training. A city contract was awarded to KLW Construction and La Paz Plastering for the renovation. The scope of work was to remove the existing brick veneer and replace the brick with new stucco.

The general contractor, KLW Construction; installed a water-proof membrane, Bituthene by Grace, over the entire structure. We began the lathing phase by installing aluminum trim and revels as specified by the City Architect. Here, a lather is installing "FRY JPM" around all terminations. We further installed a plaster channel screed, Fry PCS 75-200, to create a 2" revel around the bottom perimeter of building.

Galvanized metal lath was installed over existing concrete throughout the building. We used a propane-fueled concrete fastening gun, a "Track-Fast System" by Ramset to attach the lath. Here, the Fry plaster revels are shown on the lower elevation.

After the lathing is complete, it's time to apply the stucco. Because of the size of the building and it's height, we pumped the stucco using a plaster pump. The stucco is sprayed at 1000 p.s.i. and sent up a heavy-duty concrete hose. Here, the "nozzle-man" is applying the stucco and is followed by a crew of plasterers who finish and clean behind him.

This view is from the roof of the tower showing the ground staging of the project. The portland cement stucco, was supplied by BMI, formally Maxit. The material is contained in a large 28' silo and fed into the plastering pump. Here you can see the silo, pump, hoses and rigging which are sent to the plastering crew working on the top floors.

The scratch coat is the first coat of stucco applied to the building, followed by the "brown" or leveling coat. A nice view of San Francisco neighborhood "Bernal Heights" is in the background.

Image 10: Completed Project
The project was completed with a finish coat of La Habra Stucco, color was a custom match from the original brick veneer. The City of San Francisco can now continue training firemen and women to protect the world's most beautiful city from international terrorism and the inevitable specter of earthquakes. Congratulations and accolades to the SFFD for the 2006 centennial of the 1906 fire and earthquake.
