PDP Engineering delivers specialized civil engineering solutions for complex transportation, port, rail, and infrastructure programs. Our experience spans major public agency and private-sector assignments, with a strong foundation in ports and maritime infrastructure, rail and transit systems, roadway improvements, utility coordination, drainage, permitting, and construction-phase support. Across each engagement, PDP Engineering brings a practical, technically rigorous approach focused on advancing projects from planning and design through agency coordination and implementation.

In the Ports & Maritime sector, PDP Engineering supports large-scale capital improvement programs involving intermodal yards, terminal modernization, bridge and roadway modifications, utility relocation, drainage infrastructure, and marine-adjacent civil improvements. Our team understands the operational, stakeholder, and permitting complexities unique to active port environments and provides solutions that align engineering requirements with construction feasibility and long-term program objectives.

For Rail & Transit projects, PDP Engineering offers experience in track-related civil design, rail corridor improvements, yard access and expansion projects, staging and phasing strategies, inter-agency coordination, and technical documentation supporting design development and approvals. We understand the multidisciplinary coordination required for rail infrastructure and provide focused support that integrates civil, operational, utility, and permitting considerations into a cohesive design approach.

In the Roadway and Highway space, PDP Engineering provides design support for roadway realignments, widening improvements, intersection design, geometrics, complete streets considerations, ADA compliance, bicycle-related elements, utility coordination, drainage, and cost estimating. Our team contributes to projects requiring careful balancing of mobility, safety, constructability, and jurisdictional requirements, particularly in urban and industrial settings.

PDP Engineering also provides a broad range of core civil engineering services that support successful project delivery across market sectors. These services include general civil design, 3D design and modeling, drainage and hydrology/hydraulic analysis, stormwater and drainage systems, utility engineering, third-party utility coordination, design reviews, basis of design development, technical and engineering reports, value analysis, cost estimating, programming and funding support, and design services during construction.

A key strength of PDP Engineering is our ability to help clients navigate complex permitting and agency coordination processes. Our experience includes support involving agencies and approvals such as CPUC, LABOE, LADOT, Caltrans, and LADBS, as well as broader inter-agency coordination required on challenging infrastructure programs. This capability allows PDP Engineering to support not only sound technical design, but also the procedural and stakeholder management elements necessary to keep projects moving forward.

Whether serving as package lead, design support, construction support, permitting support, or technical advisor, PDP Engineering is committed to delivering responsive, high-value engineering services that help clients execute critical infrastructure improvements with confidence.
