The tunnel, constructed by the Sequential Excavation Method (SEM) or New Austrian Tunneling Method (NATM), also includes seven mined cross passages that connect the in-service third and fourth bores and serve as emergency exits.
Central Subway Tunnel Project, San Francisco, CA
Principal-in-Charge, Project Manager and Engineer-of-Record
The Central Subway Launch Box was located on Fourth Street underneath the I-80 overpass structure in San Francisco. Dr. Lindquist designed the cross-lot bracing system to restrain the contractually specified slurry diaphragm walls and provided peer review for the contractor-proposed alternate (SPTC) diaphragm wall design. He also designed the temporary street decking system consisting of transverse steel beams that were supported on the SPTC walls onto which precast concrete deck panels were installed. The designs had to accommodate construction using low overhead equipment working under the freeway overpass.
Central Subway Stations Project, San Francisco, CA
Principal-in-Charge, Project Manager and Engineer-of-Record
The Chinatown Station included a deep headhouse that was utilized for access to mine the light rail station using the Sequential Excavation Method (SEM). Dr. Lindquist was engineer-of-record for the temporary internal bracing system installed in the headhouse excavation and managed the design of the construction equipment trestle that sat atop the headhouse structure. Limited workspace within Chinatown and variable subsurface geology were a couple of the design challenges posed by the station site. The designs were sufficiently flexible to accommodate changes to the decking and re-bracing requirements resulting from the revisions to the Contractor’s sequencing approach and means and methods that arose during construction. Dr. Lindquist assisted the contractor with the technical evaluation of their claim associated with the mining of the SEM station cavern in the Franciscan Formation and also served as Brierley’s Principal-in Charge for permanent structural steel detailing at the Union Square Market Street Station.

Bertha TBM Access Shaft – Alaskan Way SR99 Tunnel, Seattle, WA
Principal-in-Charge and Project Manager
Dr. Lindquist was the principal-in-charge of the design of the 80-foot inside diameter unreinforced secant pile rescue shaft. The rescue shaft was comprised of overlapping secant piles that ranged in diameter from 3 feet to 10 feet. Settlement Mitigation Piles (SESMP’s) had been installed along each side of the TBM alignment to control tunneling-induced ground deformation; therefore, it was necessary to interweave the rescue shaft secant piles and the SESMP’s and grout the interstitial spaces to create a continuous wall. Brierley’s scope also included the TBM cradle design, dewatering design, gantry crane foundation analyses, and instrumentation.
Silicon Valley Clean Water, Front of Plant Project, Redwood City, CA
Principal-in-Charge, Project Manager and Engineer-of-Record
Dr. Lindquist led the Brierley design team for the combined Receiving Lift Station (RLS) and Surge and Flow Splitter (SFS) shaft structures for the Shea-Parsons JV progressive design-build team. The SFS was used as the receiving shaft for the adjacent Gravity Pipeline project tunnel. The shaft structure is two interconnected circular slurry diaphragm walls with cast-in-place reinforced concrete liners and reinforced concrete base slabs. The slab of the larger and deeper RFS is anchored against hydrostatic uplift using deep barrettes. The RLS and SFS were excavated to depths of 92 feet and 88 feet and finished inside diameters of 66 feet and 34 feet, respectively. The site soil conditions include a thick layer of soft Bay Mud and the design groundwater level is at the ground surface. The shaft design considered all stages of construction and was prepared to conform to California Building Code and ACI 350 requirements. Detailed static and seismic soil structure interaction analysis was performed to demonstrate the structural sufficiency of the shaft design.

Texas Capitol Complex Phase 1 Expansion – Retention System Design and Construction, Austin, TX
Principal-in-Charge
The Phase 1 Expansion included the construction of two new State office buildings and five levels of underground parking to the existing complex. Given the project’s urban setting, significant coordination with adjacent major structures and utilities was necessary, which Brierley used Revit modeling to accomplish. Brierley provided design of the phased retention system for the approximately 40 to 65 feet deep, 500,000 cubic yards of excavation through overburden and limestone bedrock to construct the below-grade structures. The retention system was a combination of soil nails, solider piling with tiebacks and rock anchors with a shotcrete facing. Due to the substantial scope of excavation, a significant number of utilities were temporarily located on a 150-foot span structure over the excavation. Brierley provided the structural design for this utility support, requiring extensive coordination with the excavation support and existing utilities located underneath the foundations. The excavation was located directly adjacent to several large building structures complicating the design and required additional support elements to ensure these structures were not affected by the construction. Dr. Lindquist was principal-in-charge of this project.
