Dwarakeswar "Dwarak" Penubolu, Chief, Encroachment Permits Branch 
Dwarak Penubolu

Dwarakeswar Penubolu has been a champion for highway and public utility infrastructure enhancement projects on the State Highway System (SHS). Throughout his career—and in his current role as the subject matter expert on Caltrans’ encroachment projects— his proactive and collaborative efforts have greatly influenced managing the co-existence of utility and highway infrastructure within the State right-of-way.

Dwarak initiated and led the development of Encroachment Permit Document Retrieval System (EPDRS) to provide a searchable digital library of more than 750,000 encroachment projects with secure online access to staff. The implementation of the EPDRS resulted in a 70% reduction in staff time as well as increased data quality and reliability.

In 2018, he initiated the migration of the encroachment program operations away from paper copies to a digital platform. By 2020, the effort culminated in a complete transition to a paperless environment, which enables the public to electronically submit, obtain, and coordinate most activities associated with the encroachment process.

Dwarak is also an active and regular participant with the Transportation Research Board in several capacities including the Standing Committee on Maintenance and Operations Management and the Standing Committee on Tort Liability and Risk Management. Additionally, he is an active member of the American Society of Civil Engineers for both professional and youth programs.

The Karl Moskowitz Award annually recognizes contributions by Caltrans registered engineers to the field of transportation engineering. Mr. Moskowitz served as a Caltrans traffic engineer for 27 years. Much of his work in freeway design and traffic flow appeared at the outset of the Interstate highway program and was used extensively by planners and engineers nationwide, thus becoming the national standard.

Antonette Cuadra Clark, Office Chief - Office of Standards and Procedures 
Antonette Clark

Throughout Antonette Clark’s 35-year career in Caltrans, her mission has been that of pioneering new ways of doing business by continuously improving project development and design guidance, procedures, and processes.

Antonette has led a multidisciplinary team to promote the concept of Design Flexibility. She rolled out an education campaign, Design Flexibility Roadshow, to promote and demonstrate the benefits of using design flexibility in engineering and design decisions to provide multi-modal transportation solutions for all travelers, not just motorists.

For the last 7 years, she has led numerous efforts to develop new and update existing project development and design guidance to incorporate and promote the selection of pedestrian and bicycle facilities. This has enabled Caltrans to achieve Complete Street solutions in highway projects.

She continuously demonstrates Caltrans’ core values through her interactions in orderto ensure all perspectives are heard. Antonette strives for all to have an equitable opportunity to share their needs, and she regularly seeks the “out of the box” idea. Antonette is not content with the status quo.

Whether it is creating design guidance to ensure modality, enhancing safety design criteria for workers, or providing designers the innovative guidance and tools to perform their jobs, Antonette continues to strive for the safest and most reliable transportation system for all people.

The Charles H. Purcell Award recognizes valued contributions by Caltrans engineering managers to the field of transportation engineering and transportation program management. Mr. Purcell served as California’s State Highway Engineer from 1928 to 1943 and as Director of Public Works until 1951.

Bimla G. Rhinehart Award

Stefan Galvez-Abadia
Division Chief
District 4, Division of Environmental Planning and Engineering

Stefan Galvez-Abadia, Division Chief, District 4, Division of Environmental Planning and Engineering 
Stefan Galvez-Abadia

Stefan Galvez-Abadia is a dedicated team member working on some of District 4’s most challenging projects. He stepped in as the Environmental Manager of the San Francisco Oakland Bay Bridge (SFOBB) Project—the largest single project in Caltrans history— during the final phases of construction of the new east span and the dismantling of the original east span.

Stefan directly oversaw the demolition of the former east span. This included above-water demolition of the steel cantilever and superstructure, the unprecedented use of controlled implosions in the Bay to remove 18 underwater foundations, and the construction of two new world-class public open spaces built atop former bridge foundations. The California State Audit found that the use of controlled implosion to remove foundations was a central factor in helping the overall SFOBB Project reduce its schedule by 4 years, while saving the state $94 Million.

The final phase of the project involved the construction of two public access piers built atop former bridge foundations: the Bimla G. Rhinehart Vista Point and the Oakland Public Pier at John C. Sutter Regional Shoreline. These new public amenities delivered public Bay access to residents and visitors. Stefan played a critical role in developing the concept, building stakeholder consensus, and ultimately obtaining regulatory approvals to construct these public piers, from which the public will benefit for generations to come.
