He is a Senior Supervising Engineer with a high level of expertise in the design and analysis of suspension bridges. He has a solid fundamental understanding of structures and can apply his knowledge exceptionally well to the design and analysis of highly complex structures. He is also a strong communicator, able to identify and distill the key information that is relevant to the task at hand and present it in a clear and quickly understandable manner.

He is a very talented engineer with years of professional experience. He has more than 25 years of professional and teaching experience in geotechnical earthquake engineering, bridge engineering, and construction engineering. He has performed technical oversight and review of the geotechnical and earthquake engineering activities for the seismic retrofit of all toll bridges and road tunnels in California. He has been responsible for developing the seismic design criteria for Caltrans bridge abutments and tunnel structures. He has developed state-of-the-art computer software for seismic analysis and design of earth retaining systems, including implementing the AASHTO LRFD recommendations for retaining structures and bridge abutments. He has developed Section 5 of the Caltrans' Bridge DesignPractice manual “Lateral Earth Pressure and Retaining Structures.”

He has a passion for engineering, and he has worked on so many prestigious projects. He received a bachelor’s and master’s degree in civil engineering in Utah and a doctorate from the University of Southern California. He landed a job at the California Department of Transportation (Caltrans) in 1987, where he provided technical oversight on seismic retrofitting of toll bridges and tunnel structures. He moved up quickly and helped write numerous manuals on trenching and shoring for excavating. He had a hand in Caltrans’s latest Seismic Design Criteria, which came out last November. The manuals are used worldwide for highway and rail construction and retrofitting.

Many countries, including Japan, Turkey, India, Guatemala, and Russia, have paid them to train their engineers about designing earthquake-resistant structures. He has been a lecturer at the University of California, Irvine. He regularly appears before the Caltrans' Seismic Advisory Board, an independent panel that scrutinizes policies, rules, and plans for construction in earthquake-prone California.

He is a Senior Structural Engineer in the Tampa Office of AECOM (formerly URS). He is involved in preliminary and final bridge design in both steel and concrete. He has been active in several bridge design projects, including segmental concrete structures, steel box girders, and long-span cable-stayed bridges. His technical expertise includes structural analysis and design with an emphasis on computer modeling and diverse computer applications. He is also experienced in time-dependent and linear and non-linear finite element analysis. Typical projects are described below.

He was a staff structural engineer for the design on the MIC – Earlington HeightConnector segmental portion, featuring 13 units with a total length of 1.1 miles of constant and variable depth and width precast box girders in Miami, Florida; ten post-tensioned concrete box girder segmental bridges on the SR 826/SR836Interchange in Miami, Florida; and for the eight segmental bridges on the Big-I Interchange in Albuquerque, New Mexico. The design of these bridges was done, taking into consideration the balance cantilever method of construction. Also, he was involved in the final design of both the steel and concrete alternate for the extradosed stayed-cable bridge on the Pearl Harbor Memorial Bridge in New Haven, Connecticut (I-95 crossing the Quinnipiac River with an estimated cost of$100million).

He is a structural engineer at GM2 Associates, Inc (Hartford, CT) with experience in design, modeling, and analysis of various types of bridges, including steel, arch, prestressed concrete, NEXT beams, box culvert, and pipe arch. He also has practical experience in bridge design and load rating, preparation of contract plans, bridge rehabilitation study reports, bridge demolition and erection analysis, design services during construction, among other aspects of bridge engineering. Proficient in various structural analysis software, including MIDAS/civil, AASHTOWare BrR, and CANDE.

He has more than 15 years of experience in bridge design. Since 2013, he joined V-con as an executive director and senior bridge engineer. V-CON is a member of the VALBEK group and designing and consulting engineering office specialized in Steel and concrete bridges Bridge building technologies, Steel structures – detailed design.

Patrick has six years of experience in design and modelling for local and international infrastructure projects. He is knowledgeable in both Structural and Highway design with familiarity of Australian, Middle East, British, American, and Philippine standards.

His experience includes bridge, tunnel and civil structure design, highway alignment and profile design, surface modelling and analysis and more.
