Verification Infiltration Testing for the Stormwater Management Design for a Light Rail Extension Project in Washington State

Roy E. Jensen, Blake Lytle-Goldstein, William F. Hickey, Madan B. KARKEE et autres

Stormwater management was a critical element of the Downtown Redmond Link Extension (DRLE) project. This project exemplified the power of interdisciplinary collaboration, requiring close coordination among civil engineers, hydrogeologists, and construction teams to achieve success. Due to shallow groundwater and flat topography, …

Geotechnical Performance-Based Seismic Design for Tall Buildings in Seattle

Michael Chamberlain, Madan B. KARKEE, Doug Lindquist

Many of the advances in performance-based seismic design (PBSD) originated in Seattle, where a community of structural and geotechnical engineers specialize in tall building design and code development. This paper presents the history and practice of the geotechnical engineer’s role in performance-based …

Geotechnical and Structural Adaptations for the Seismic Design of a New Ferry Terminal in Washington

Madan B. KARKEE, Garry E. Horvitz, Michael B. Chamberlain, Andrew J. Gastineau et autres

The new Mukilteo Multimodal Ferry Terminal in Washington State opened in December 2020 and replaced the seismically vulnerable ferry terminal located less than half a mile southwest that was built in 1957. The new terminal was designed to better serve the Mukilteo-Clinton …

Challenges in Dewatering for Underground Construction in Flowing Artesian Conditions: A Case Study

Roy E. Jensen, Madan B. KARKEE, Doug Lindquist

An underground 1.9-mi-long (3.1 km) sanitary sewer line was designed and constructed in the greater Seattle area. Once completed, substantial groundwater seepage was observed within a 600-ft-long (183 m) segment of the pipeline. The repair to arrest the seepage cost over $1 …

Estimation of Vs profile using its natural frequency and Rayleigh-wave dispersion characteristics

Ken Tokeshi, Madan B. KARKEE, Carlos Cuadra

Abstract. The evaluation of the natural frequency of random Vs profiles before analyzing the fundamental Rayleigh-wave dispersion characteristics is proposed in this paper. The inclusion of this parameter optimizes the effectiveness of random inverse searching to estimate Vs profiles. To demonstrate this …
