WELCOME
We design permanent and temporary systems with an emphasis on earth retaining structures and structural shoring. We also engage on a variety of engineering services to owners and contractors on private and commercial projects throughout the West Coast. We also are licensed in the state of Nevada.
OUR SERVICES
* Preparation of detailed engineering plans and calculations
* Feasibility studies
* Peer reviews
* Cost estimating
* Inspections / Testing

FEATURED PROJECTS:
560 Mission Street, San Francisco, CA
This site is in a very tight urban environment and presented many obstacles and challenges. SPI Consulting Engineers, Inc. was able to design a completely tiedback open excavation system that cutoff water and maintained a dry site for construction of two levels of underground parking.

333 Fremont Street, San Francisco, CA
Site Overview: This project demonstrated a number of our shoring techniques. There were hand dug underpinning piers to support an existing structure, soldier beam walls with multiple tieback-levels to retain adjacent cuts up to 45-feet deep. External wales provided lateral support for an 18-foot wide “peninsula” retaining a 30-foot cut. The photograph to the right shows how the "peninsula" walls were tied together where tiebacks or soil nails could not be used due to space limitations.

Stanford University Medical Center, Palo Alto, CA
Site Overview: this project showcased our problem-solving skills. The original design called for removing underground storage tanks 14 feet below grade. After attaining this depth the tanks were removed but the Stanford Redevelopment Agency requested that contaminated soils be removed a minimum 7 feet below the bottom of excavation. Because this over-excavation would have caused stability issue to both surrounding structures and the temporary shoring system we designed a second row of tiebacks with wales to resolve the problem. This is a finished photograph of soldier beam wall with the additional row of tiebacks and wales. We were able to revise our design and meet our clients’ request in a safe manner.

Alemany Pump Station, San Francisco, CA
Site Overview: this project demonstrated a number of our design techniques. Soil nail walls with shotcrete lagging were designed to support the temporary lateral soil loading during excavation at the main pump station area. Because the job location was nearby sensitive facilities, we paid extra attention to construction sequences and public safety. We also provided special inspection service during construction phases. This is a progress photograph of soil nail wall installation. Cuts up to 25-foot high were retained.

Retaining Walls at the Happy Valley Golf Course in Pleasanton. The walls are designed to work with or without the ponds being filled with water on either or both sides of the road fill.
