Bridges

DLZ’s bridge expertise is nationally recognized. We deliver small structures with the same care that we do multi-million-dollar landmarks. Further, our team designs, inspects, and rehabilitates the range of bridges, from highways to rail to trail. With a diverse portfolio that includes design-builds and innovative use of funding, DLZ is your bridge resource.

We are proud to be considered a Top Design Firm. With multiple disciplines in-house, our team leads projects from the early planning stage through construction. We also offer many services that support our design work, including:

    • Inspection and scour analysis
    • Load rating studies
    • Temporary structures
    • Soils and foundation testing and design
    • Construction inspection and management
    • Hydraulic analysis
    • Accelerated construction
    • Bridge asset management

Bridge Inspection

DLZ engineers provide inspection and rating services in accordance with the National Bridge Inspection Standards (NBIS) and Reports.

We provide a detailed visual inspection of each structure. Any deterioration receives an in-depth inspection including sounding concrete surfaces and measuring section loss found at steel members. We also calculate bridge load ratings, prepare SI&A forms and a summary report outlining inspection findings and various recommendations such as listings of sign postings and schedules for bridge replacement, rehabilitation, and repair.

We work with government agencies and private entities of all sizes, so we understand that you need to make the most of a limited budget.
