Raymond Tritt
Raymond Tritt

Raymond Tritt, Chief Office of Special Projects
Division of Design

Ray has established himself as Caltrans’ innovative contracting expert, by responding to the ever-increasing need to deliver quality transportation projects in less time and at reduced costs. He has spearheaded the Department’s transition to more innovative contracting methods such as design-sequencing, design-build, construction manager/general contractor (CMGC), additive bidding, and job order contracting as viable alternatives to the conventional design-bid-build method of contracting.

Ray authored legislative proposals and drafted legislation that led to Caltrans receiving authority to begin pilot programs for design-sequencing, design-build and CMGC. He is also leading a similar effort, which could give the Department authority to use job order contracting. He partnered with the California Department of General Services, Federal Highway Administration, American Association of State Highway Transportation Officials (AASHTO), other states’ departments of transportation, and industry to gather best practices and lessons learned, while leading the development of the Department’s standards, policies, guidance, tools and training involving the various contracting methods.

Due to his on-going efforts, AASHTO has given Ray several awards and recognitions.

In addition, under Ray’s leadership, the Design-Build Institute of America (DBIA) recognized Caltrans as the 2013 DBIA Transportation Owner of the Year.

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. He established California’s extraordinary record of leadership and integrity in transportation engineering and guided the construction of the San Francisco–Oakland Bay Bridge and the State Highway System.

Paul McClintic, District Traffic Operations Engineer
District 5

Paul is the District 5 traffic operations engineer and manages the Traffic Operations Branch in San Luis Obispo. He has nearly 25 years of experience with Caltrans and has spent the past 20 years in Traffic Operations in various areas, including accident investigator; field liaison; traffic plans, specifications and estimates preparation; level of service analysis; intergovernmental document review; encroachment permit evaluation; speed limit determinations, and as the State Highway Operation and Protection Program mobility program manager.

Before his current position, Paul was the traffic safety investigator for Santa Barbara and San Luis Obispo counties and served on several safety corridor task forces. He has been a roundabout advocate, working to elevate the use of roundabouts on state highway locations for both safety and operational benefits. He was involved with roundabout installation in Santa Barbara, which were some of the first roundabouts on the California state system.

Throughout the course of his career, Paul represented the state at dozens of open houses, public hearings and town hall meetings, describing the benefits of new interchanges and roadwork projects. He has also been a subject matter expert working with the Department of Consumer Affairs State Board of Registration to develop questions and participate in practice exams for traffic engineer registration.

Paul helped develop curriculum for a traffic academy and a traffic investigation course. He has successfully helped defend Caltrans in five litigation cases. His investigations led to numerous improvements that enhanced the state highway system’s safety.

The Karl Moskowitz Award recognizes contributions by Caltrans registered engineers to the field of transportation. 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.


Mark Mahan

Mark Mahan, Senior Bridge Engineer
Division of Engineering Services, Structure Policy and Innovation

Mark has more than 25 years of sustained excellence in earthquake engineering for bridges both in California and nationally. He was instrumental in developing guidance and tools to support change, which ultimately led to Caltrans being the national and international leader in earthquake engineering and seismic bridge design.

Largely in part to Mark’s software and seismic design guidance, Caltrans was the first government agency worldwide to adopt the displacement-based seismic design philosophy, which has since been adopted nationally in the American Association of State Highway and Transportation Officials (AASHTO) Guide Specifications for Load and Resistance Factor Design Seismic Bridge Design.

The Federal Highway Administration, AASHTO and many states have also recognized Mark for his national efforts developing the AASHTO seismic design specification and helping other states apply displacement-based seismic design specifications

The American Society of Civil Engineers named Mark the 2012 winner of the Norman Medal. He was recognized for his work as the first author on a paper entitled “SANISTEEL: Simple Anisotropic Steel Plasticity Model,” which was published in the February 2011 issue of the Journal of Structural Engineering. He received the medal along with his four co-authors from the University of California, Davis.

The public’s benefit of Mark’s design tools and guidance can best be characterized by their end product—a much safer and resilient California transportation network.

The James E. Roberts Award recognizes outstanding contributions by Caltrans registered engineers to the field of transportation structures. James E. Roberts served as a structural engineer and manager for more than half a century, including 15 years as California’s State Bridge Engineer. He spearheaded Caltrans’ $4.5 billion seismic retrofit program and oversaw nearly $50 million in seismic research projects. He was named to the National Academy of Engineering in 1996, and was the only state-employed engineer to be so honored. Mr. Roberts retired in 2001 as Chief Deputy Director.

Andrew P. Nierenberg, Deputy District Director
District 7, Right of Way Division

Andrew is the District 7 Right of Way Division Deputy Director and leads the district’s Right of Way staff in delivering a challenging, complex, and dynamic workload. His focus and ability to cultivate teamwork and confidence in Caltrans’ mission inspires his staff to excel.

Andrew’s recent achievements include leading the Right of Way team to deliver timely right of way certification for the Interstate 5 Widening and Carpool Lane projects, which affected more than 500 industrial, commercial and residential parcels in southeast Los Angeles.

Andrew faced numerous challenges and concerns from various local public agencies, impacted businesses, and residential property owners contesting the acquisition of their property. To resolve their concerns, he held countless meetings with stakeholders, remained accessible and flexible to problem-solve for fair solutions that did not compromise the ultimate project delivery. In addition, his determined efforts helped hundreds of displaced residents relocate to comparable housing debt-free.

Through his 14-year-stint as coordinator and instructor for the Real Estate Program through California State University, Northridge, Andrew has also gifted the right of way community and for one year served as the visiting professor in the Public Administration Program at California State University, Los Angeles. He applied his craft to his master’s thesis on policy formulation and implementation of the Interstate 105 Century Freeway Housing Program.

Andrew was destined to be in the right of way business. His father also worked for Caltrans in Right of Way, and his parents named him with the initials of “Assessor’s Parcel Number.”

Norma Ortega, Chief Financial Officer
Division of Finance

Norma has been Caltrans’ Deputy Director of Finance/Chief Financial Officer since 2009. She is responsible for the Department’s financial management and policy as well as federal and state transportation project programming. She oversees Caltrans’ $13 billion budget.

Throughout her 28-year career, Norma has served in a number of increasingly responsible fiscal management positions and led a number of strategies designed to keep funds flowing. These strategies include aggressive cash management of funds during very challenging fiscal times, which allowed projects to continue through numerous years of funding stops and starts.

Her efforts have resulted in the federal approval of nearly $5 billion in federal toll credits, reduction of federal inactive obligations, and capturing more than $1 billion of additional federal funds from others states through the August redistribution of funds.

Norma’s leadership has assured that billions of dollars of transportation projects have continued to move forward in California. This translates to millions of people being employed building road projects and to the traveling public being assured of a better transportation system.

The Emerson Rhyner Award recognizes contributions to the field of transportation by nonengineering Caltrans managers.
