Mike Greenfield, PE, PhD

Owner and Principal Engineer at Greenfield Geotechnical

Dr. Greenfield is principal engineer of Greenfield Geotechnical. His primary design focus is in developing resilient, performance-based, and economical geotechnical and earthquake engineering solutions for buildings, bridges, piers, tanks, and other elements of the built environment. He completed his M.S. at Virginia Tech with a research focus on downdrag of pile foundations and his Ph.D. at the University of Washington with a research focus on the effects of liquefaction during long-duration ground motions. Since moving to the Pacific Northwest in 2008, Dr. Greenfield’s notable projects include deep excavations below groundwater for commercial and industrial facilities, marine cofferdam cells and bulkhead walls on the Oregon coast, pile-supported piers and wharves along the Willamette and Columbia Rivers, and drilled shaft and auger cast pile-supported buildings in downtown Portland and Hillsboro. He is licensed as a Professional Engineer in Oregon and Washington.

Andrew Makdisi, PE

Geotechnical Engineering PhD Candidate at University of Washington

Mr. Makdisi is a PhD Candidate in Geotechnical Engineering at the University of Washington. His doctoral research work focuses on earthquake-induced soil liquefaction and its effects on critical infrastructure. Mr. Makdisi received his B.S. in Civil Engineering from the University of California, Davis in 2012, and M.S. in Civil Engineering from the University of Washington in 2016.  During his Masters studies, he spent 8 months as a visiting researcher at the Norwegian University of Science and Technology in Trondheim, Norway. Prior to returning to UW for his Ph.D., he worked for two years as a senior staff geotechnical engineer at Hart Crowser in Seattle, Washington, and has continued to consult on a number of projects around the world. He is a registered professional engineer in the state of California.

Course Title: Deep Foundations and Excavations

Delivery Method: Live Online

Course Description: This seven-hour course examines earth pressure theory, braced excavation design, construction considerations, and deep foundation design.

Learning Objectives:

Learning Objective 1:
Learners will be able to recognize and discuss the roll of earth pressure theory in the excavation for a deep foundation and for the foundation itself.

Learning Objective 2:
Learners will be able to identify construction processes and design considerations for braced excavations.

Learning Objective 3:
Learners will be able to identify construction processes and design considerations for deep foundations.

Learning Objective 4:
Learners will be able to describe the purpose and methods of testing the integrity and static load capacity of deep foundations.

Learning Objective 5:
Learners will be able to discuss the theory, mechanics, and structural consequences of downdrag, which has resulted from seismic activity.
