OVERVIEW
At American Subsurface Engineering, we deliver intrinsic, recognizable value to owners, A/E firms, and contractor clients by focusing on constructability, efficiency and practicality. Our geotechnical and structural design and consulting services are founded on a fervent understanding of our clients’ needs, subsurface conditions, site-specific constraints, and the risks associated with the construction of underground structures.
Bryan G. Cortnik, MS, PE, SE
Geostructural Engineer
Bryan is au fait in his craft with over 23 years of diverse experience in the design of different building types ranging from new buildings to retrofit of older buildings. He is a thought leader in the field of temporary shoring and permanent earth retention, and foundation systems. His experience with excavation shoring includes cantilevered, braced, and tied-back soldier piles, soil nail walls, underpinning, and secant pile walls. Pile foundations include the design of augercast piles, CIDH piles, soil mixing, and micropiles.
A native Californian, Bryan is well-traveled in the US due to his service on both local and national engineering committees for Deep Foundation Institute (DFI), National Council of Structural Engineers Associations (NCSEA). Bryan has also served on the Seismology Committee at the local and state levels for the Structural Engineers Association of California (SEAONC and SEAOC), including as a past Seismology Chair with SEAONC.
Bryan is the sole author of a peer-reviewed publication titled “Excavation Shoring Design Guide,” a practical design guide for practicing engineers published by NCSEA.
