Civil Engineer Specializing In Geotechnics
Diplomate | D. GE | AGP- ASCE

Ed Ulrich graduated from Georgia Tech in 1969 with a Bachelor of Civil Engineering and concentrations in George Sowers Foundations, structures, and surveying, but he began his career in 1967 as a part time field engineer in Atlanta foundation projects.  After one year as a Construction Engineer he entered the University of Illinois at Urbana-Champaign in 1970 to study rock engineering, foundation engineering, engineering geology and tunneling. Upon graduating with an MSCE he returned to Atlanta for another year, and then crossed the Sabine in 1972 to join McClelland Engineers. By 1980 he became chief engineer for tall buildings and braced excavations and started Ulrich Engineers in 1984.

For 12 years, Ed served in a variety of capacities at McClelland Engineers. He directed foundation assignments offshore, and on three continents, thus becoming aware that construction means and methods governed foundation design.  His noteworthy local projects include:

  • “The World’s Tallest Soil Supported Building – [Texas Commerce Tower] Chase Tower at 75 stories”
  • “The World’s Tallest Suburban Office Building – Transco Tower at 64 stories”
  • The Wortham Theater Complex
  • “ENRON Building 2”
  • Calpine Tower
  • The Houston Rockets Toyota Arena
  • Texas Medical Center Smith Tower

Earning the Title “Dr. Dirt”

In the mid 1980’s, Ulrich Engineers, Inc. was called upon to guide the design and construction of the new Harris County Jail Complex. This was the most ambitious contribution to the Houston Central Business District since building the 75-story Chase Tower, the world’s tallest soil-supported building. The jail project consisted of building new structures and the rehabilitation of an existing cold storage warehouse, all on the banks of old Houston waterways. Specifically, the constructions involved the following elements:

  • Old Warehouse
  • New Jail
  • Connecting Bridges
  • Additional Tunnel
  • Processing Center
  • Old Jail

The assignment was particularly challenging in that the success of the foundation design depended largely on the understanding of foundation conditions at the close of the 18th century. A major slope failure had already occurred and had destroyed the original site.

Ulrich Engineers, Inc. guided the design and construction of foundations, planned necessary repairs that would allow the failed site to be developed, supervised construction, and designed a scheme which doubled the height of the cold storage warehouse to form the new jail without needing new foundations… all feats unequaled in Houston history.

The owner-developer and contractor honored Mr. Ulrich with the title, “Dr. Dirt,” for his leadership in the project foundation engineering because he played an enormous part in the success of the project. This title continues to be synonymous with the Ulrich Engineers team today.
