Services
Integrated Expertise Across Every Mode
From rail signaling to highway technology to electrical systems coordination — David Schafhirt Consulting delivers the technical depth that complex transportation programs require.
What Sets This Practice Apart
Most consultants specialize in one mode or one phase. David Schafhirt Consulting operates across the full spectrum of transportation systems integration — from initial concept and procurement support through design, construction, testing, commissioning, and operations.
That breadth, combined with direct experience working with California agencies, transit authorities, and large contractors, means every engagement is grounded in how these projects actually get built and delivered.
Systems Integration
Coordinating Complexity Across Multi-Vendor Programs
Transportation infrastructure projects involve dozens of systems, vendors, and interfaces that must work together precisely. David Schafhirt Consulting provides the technical leadership to define integration requirements, manage interfaces, and ensure systems perform as a unified whole — from initial design through final acceptance.
Rail & Transit
Signaling, Communications, and Control Systems
Rail and transit programs demand precision at every level — from wayside signaling and communications-based train control to passenger information systems and operations control centers. David Schafhirt Consulting brings hands-on experience with light rail, heavy rail, and regional transit programs across California.
Road & Highway
Intelligent Transportation Systems and Infrastructure Technology
Modern highway programs integrate traffic management, tolling, incident detection, and communications infrastructure into complex systems that must operate reliably at scale. David Schafhirt Consulting provides technical advisory and integration support for ITS deployments, managed lanes, and highway technology programs.
Electrical Systems Coordination
Traction Power, Distribution, and Electrification
Transportation electrification — from traction power substations to overhead contact systems to facility electrical distribution — requires close coordination between electrical contractors, systems integrators, and agency stakeholders. David Schafhirt Consulting bridges the technical and programmatic gaps that cause delays and cost overruns.
Agency & Government Consulting
Technical Advisory for Public Infrastructure Owners
State agencies, transit authorities, and public infrastructure owners need independent technical expertise they can trust — advisors who understand both the engineering and the procurement, regulatory, and political environment in which California infrastructure gets built. David Schafhirt Consulting provides that trusted advisory role.
