The Tudor Engineering Company Records were given to The Bancroft Library by Robert Janopaul on March 12, 2007.
The Tudor Engineering Company was founded in San Francisco in 1950 by the late Ralph A. Tudor, a West Point graduate and retired
Colonel in the U. S. Army Corps of Engineers. Mr. Tudor established a nationwide reputation for excellence following his involvement
in the design and construction of the San Francisco-Oakland Bay Bridge and other bridges in the San Francisco Bay Area.
The firm's early assignments were the design and construction management of several long span bridges across the Colombia
River between Washington and Oregon and across other major waterways in the Pacific Northwest. In addition to highway and
bridge work, the firm developed expertise in the water resources field, including a major hydroelectric project in the Sierra
Nevada mountains of California during the mid 1950s.
In the early 1960s, Tudor Engineering played a major role in the design and construction of the Tagus River Bridge project
in Lisbon, Portugal. The firm also undertook a major hydroelectric project for the Merced Irrigation District in California.
It designed and supervised construction of the Exchequer Dam. Located on the Merced River, it was the highest concrete-faced
rock-filled dam in the United States at the time.
The early 1960s also saw the formation of the joint venture of Parsons-Brinkerhoff-Tudor-Bechtel (PBTB), which undertook the
management of design and construction and activities for the San Francisco Bay Area Rapid Transit (BART) system. Tudor Engineering's
role in the joint venture involved civil engineering design and construction activities, including aerial structures, several
underground and above-ground transit stations, tunnels, bridges, and several train maintenance yards. The PBTB joint venture
also undertook the design of the Caracas Metro system in Caracas, Venezuela, the first phase of which was completed in the
By the completion of the BART and the Caracas systems, Tudor Engineering had developed special expertise in the design of
modern rapid transit systems. Its next major transit assignment, conducted as a joint venture with Parsons Brinkerhoff (PBT),
involved serving as the general engineering consultant for the Metropolitan Atlanta Rapid Transit Authority (MARTA) in Georgia.
The PBT team began work on this project in the early 1970s.
In the mid 1970s, Tudor Engineering was one of the first consulting engineering firms to respond to the national energy shortage
with innovative technology for retrofitting existing water resource facilities with small hydroelectric power plants. It pioneered
this technology with methodology manuals for the Corps of Engineers, the U. S. Bureau of Reclamation, and the Electric Power
Research Institute. Besides developing new innovative technology, the firm has had the lead role in the planning, design,
and construction management of more than 30 of these hydroelectric installations through the western United States.
In 1989 the Los Angeles office moved to Oakland, CA and Tudor Engineering Company merged with Kaiser Engineering in Oakland.
