Projects
 
With 38+ years of experience in geotechnical consulting, Jim Doolittle's project experience is vast.  General project catagories have included commercial developments such as business parks and high-rise office buildings, institutional buildings, custom residential development, shoreline stabilzation, residential tracts, pipelines, mass transit facilities, tanks, reservoirs, earth dams, landslides, highways, bridges, hopitals and schools. 

The following are a few of the noteable projects in Jim Doolittles experience:
 
SR-90 Eastbound Rainier Avenue Interchange
This project included several new SR-90 bridges, approach fills and interchange ramps for the east-bound lanes Rainier Avenue crossing.   Technical considerations included mitigation of soft sediments below the site and their settlement effects on the proposed bridges and existing utility corridors.
 
Mt. Vernon Waste Water Treatment Plant Additions
This project included major new structures both surface and subsurface.  Technical considerations included evaluation and mitigation of the efects of a deep layer of soft organic silt, dewatering and shoring of construction excavations and effects of induced settlements on existing structures.
 
148th Avenue Extension, Redmond
This project included a proposed connection from the existing north end of 148th Avenue at SR-908 to Willows Road.  Technical considerations included crossings of potentially unstable slopes and soft ground areas.
 

 

Seismic Hazards Evaluation, Lake Youngs Supply Line

This poject included reconnaissance, explorations and seismic analyses along the 8-mile long Seattle water supply pipeline.  Evaluations included seismic stability evaluations of steep natural slopes and liquefaction evaluations and seismic response evaluations of soft ground crossings.

Lake Youngs Inlet Dam
This project included rehabilitation of the existing dam including construction observations and consultations during foundation preparation, seepage control cut-off wall and embankment construction of this earthfill dam within the Seattle water supply system.
 

 

 

 

 

Los Angeles Metro Rail System
Project included geotechnical investigations for 18 stations and tunneling along the 18-mile underground transit system which extended from Union Station through downtown Los Angeles to West Los Angeles, through the Santa Monica mountains to North Hollywood.
