Kash Nikzad, Ph.D, PE

Kash Nikzad is the managing principal at TranTech Engineering and is directly involved in most of the firm’s projects. He is a skilled project manager and is known by clients for his positive attitude, attentive client communication, and effective team leadership. Kash has more than 20 years of experience that includes transportation-related structural analysis and design, load rating, seismic analysis, research and retrofit recommendation, and construction supervision and inspection for various types of concrete, timber, and steel bridges. He is regularly involved in all phases of design and construction for transportation projects with bridge structures in Washington and is very familiar with WSDOT guidelines. Kash’s experience encompasses feasibility study/TS&L reports, PS&E packages, contract documents, and construction support, as well as bridge load ratings, varying from complex steel truss to simple one-span bridges. Kash has contributed technical papers to well-known civil engineering journals and conferences and has written two reports on earthquake damage assessment for the EERI newsletter. His work as a member of PCI’s seismic design subcommittee yielded a report on state-of-the-art guidelines: “Design of Bridges with Precast Components for Seismic Hazard."

Project Experience

City of Tacoma, Tacoma Avenue South Bridge Rehabilitation | Tacoma, WA

Project Manager/Structural Engineer. Leading the design for the rehabilitation of this 333-foot-long and 50-foot-wide bridge located in south Tacoma. The bridge, constructed in 1930, crosses a live Sound Transit main line and Tacoma Way South. It is currently being designed for repair of the localized heavy corrosion on the existing steel elements and replacement of the exterior girders to accommodate a five-foot widening. Interesting features include replacement of both exterior girders and usage of lightweight concrete for decking. This project is federally funded through BRAC. Construction is planned for 2014.

City of Everett, Broadway Avenue Bridge Replacement | Everett, WA

Project Manager. Currently leading the design of a replacement for the Broadway Avenue Bridge, which is 100 feet long and 100 feet wide. The bridge carries five lanes of traffic and two sidewalks over the BNSF Railroad main line and a Sound Transit rail line. Prepared a TS&L report that provided three options for the bridge replacement. Currently preparing the design of the chosen alternative, a three-span bridge with a precast, pre-stressed slab superstructure.

City of Lakewood, SR 99 Overpass Rehabilitation | Lakewood, WA

Project Manager. Led this bridge rehabilitation project that consisted of adding five-foot sidewalks and throw fence to this overpass that carries the SR 99 facility over BNSF tracks.

Skagit System River Cooperative, Illabot Creek Bridge Design Project | Skagit County, WA

Project Manager. Led this salmon habitat restoration project that includes restoring Illabot Creek to its historic channel location(s), removing portions of existing dikes bordering the current channel, building bridge(s) for the Rockport-Cascade Road that spans the historic channels, and allowing the stream to flow through one or more channels as it migrates over time. River engineering design tasks include flow control upstream of the bridge site, hydrology, hydraulics, and channel restorations and modifications.

City of Bonney Lake, SR 410 Wall Design | Bonney Lake, WA

Project Manager/Senior Structural Engineer. Designed approximately 1,500 feet of wall along SR 410. Wall types included SEW and soldier pile walls up to 20 feet in height.
