All of us need to contribute to the preservation of our great history, whether it is the history of our cities, our states, or our country. Preserving our historical structures is but one way to preserve our own lives and preserve our contributions for future generations. Historical projects are a small part of our overall construction industry, but a specialty market that requires careful planning, attention to detail and careful execution since many elements of a historical project will be removed only to be put back in place later in the project. MTM Builders understands these elements and has put them into practice and on display several times in projects at our national parks, our state parks, and our military installations. These include projects at Alcatraz Island in San Francisco Bay, Fort Mason in the city of San Francisco, Yosemite National Park, Cabrillo National Monument in San Diego and at Marine Corps Air Station Yuma in Arizona.
ALCATRAZ ISLAND WATER TOWER STABILIZATION
GOLDEN GATE NATIONAL RECREATIONAL AREA
SAN FRANCISCO, CA
The scope of this project was to stabilize the 250,000 gal. Alcatraz Water Tower, designed in 1939 by the Chicago Bridge and Iron Works for the Federal Bureau of Prisons and erected in 1940. As a contributing structure to the National Historic Landmark District, any work on the structure had to meet the Standards for Treatment of Historic Properties and California Historical Building Code. The objectives of this project were to maintain the structural integrity of the water tower, apply corrosion-resistant coatings, increase the life expectancy for another 20 years, and to maintain the historic appearance of the tower. Included in the work of this project was sandblasting of existing coating and rusted areas of the water tower and replacing the deteriorated or missing steel members and ladders and applying a four-coat epoxy coating system to the entire tank.
