Bay Area Waterfront

Port of Redwood City

OVERVIEW
The Wharves 1 & 2 Replacement Project involved demolition of an existing timber wharf and construction of a concrete wharf in addition to civil engineering site improvements. The site is underlain primarily with soft to stiff clay (i.e. Bay Mud) such that long-term settlement impacts needed to be considered in time design solutions. The project includes phased demolition plans, erosion control, design-build site improvement plans, and permit acquisition of the active port as well as RCRA closure of the former Gibson Environmental facility. Grading was an important aspect of this project due to strict conformance to FEMA, sea level rise, and City Flood Plain Elevation regulations.

California Refinery – New Berth & Seismic Upgrade

OVERVIEW
Langan is the geotechnical engineer of record for the replacement and seismic strengthening of a terminal at a refinery in California. The oil terminal is approximately 1,300 feet offshore consisting of a 950-foot-long concrete and timber pier, and an approximately 3,500 foot long access trestle and pipelines. In addition, a reinforced earthen embankment (approximately 4,000-foot-long and 45 to 160- foot wide) is being constructed over marshland. Our engineering studies have been performed in accordance with California Building Code, Marine Oil Terminal Engineering and Maintenance Standards.

Crescent City Inner Harbor Rehabilitation

OVERVIEW
Langan provided geotechnical services for the Crescent City Inner Harbor rehabilitation project after it was affected by the tsunami generated from the 2011 earthquake in Japan.  The project consisted of replacing existing steel piles with concrete piles and adding additional concrete piles to support new concrete floating docks, and constructing new foundations for the three gangway landings.In addition to foundation design, we evaluated the stability of harbor slopes for both static and seismic conditions, and have provided recommendations for increasing their stability. The project won the 2016 ACEC California Engineering Excellence Award.

Eagle Rock Aggregate Storage Facility

OVERVIEW
Langan provided geotechnical consultation and observation and testing services during the construction of the aggregate storage facility at the Port of Richmond. The new facility included a large storage building to house several stockpiles of aggregate material, and a conveyor system to transport aggregate from ships to the storage building and from the storage building to a hopper system for loading trucks with aggregate. The new storage building is supported on spread footings that bear on a layer of compacted fill over soil that has been improved using jet-grouted soil-cement columns. The conveyor and hopper systems are supported on deep foundations consisting of driven precast, prestressed concrete piles.

Port of San Francisco Seismic Vulnerability Study

OVERVIEW
Langan performed a geotechnical peer review of the Seismic Vulnerability Study of the Port of San Francisco between Fisherman’s Wharf and Pier 46. The primary purpose of the study was to assess the likelihood of damage during strong earthquake ground shaking to the seawall and infrastructure within the study area.

South San Francisco Ferry Terminal at Oyster Point

OVERVIEW
The South San Francisco Ferry Terminal at Oyster Point is the first terminal to be built south of San Francisco in generations. The 4,000-SF design-build project included vehicular access and parking with an extensive canopy over the bus waiting area, a pile-supported pier structure for embarking/disembarking, a waiting area, a gangway, and a floating dock with guide-piles and protective dolphins for vessel service. After analyzing the field and laboratory test results, Langan developed conclusions and recommendations for subsurface conditions, design parameters for vertical and lateral capacities of piles, estimated settlement, general site grading, evaluation of the dynamic stability of the adjacent shoreline slopes, flexible pavement sections, site seismicity and seismic hazards, and construction considerations.
