Silicon Valley Residential/Office (Studio G)

Rick,

We have put together this web tour for you. It features some of Langan’s recent multi-family and office projects in the Silicon Valley. We look forward to working with you on future projects. Thank you.

Silvery Towers

OVERVIEW
Silvery Towers is a residential development in downtown San Jose. The project features two towers, 22 and 20 stories, above three basement levels, offering retail and residential space, including 643 apartment units and associated parking. The three basement levels required excavation of 34 to 38 feet below street grade. Langan provided multi-disciplinary engineering services for design and construction of the project. Data from the geotechnical investigation was used to reduce field exploration costs. We performed field observation and provided weekly reports regarding stormwater compliance per the Storm Water Pollution Prevention Program (SWPPP).

3877 El Camino

OVERVIEW
Plans for 3877 El Camino are to develop a mixed-use podium-style building with 11,000 SF of retail space, 17 residential units, and an underground garage. As the site/civil engineer, Langan provided site layout, grading, and utility and stormwater management design services. Working with the City of Palo Alto's utility and stormwater departments, we coordinated off-site infrastructure upgrades and designs to meet project demands. Part of our scope includes addressing the City of Palo Alto's comments on stormwater hydraulics and hydrology and stormwater treatment. We are implementing an integrated approach — with input from the entire design team — to divert storm waters into biofiltration planters instead of directly into storm drain systems, which was part of the initial design.

Mountain View at Middlefield (555 West Middlefield)

OVERVIEW
This 7-acre multifamily residential project — including a community center and a park — is an addition to low-density residential buildings built on this 14.5-acre campus. The infill development will create two residential lots with 345 residences, 974 parking spaces, 150,000 SF of open space, and 25,000 SF of residential amenity space. Per an agreement with the City of Mountain View, a 1.48 acre park will be given to the city for a community benefit. The project is pursuing LEED for Homes certification as well as various sustainable measures. Our site/civil team is providing services for a new bike lane, city-owned trail, the site/sidewalk layout, grading of off-site site/sidewalks and at-grade level podium courtyards, drainage, utilities, and stormwater management. Our geotechnical team is evaluating subsurface conditions and potential geologic hazards at the site. while our environmental team completed a Phase I Environmental Site Assessment (ESA).

5000 Shoreline

OVERVIEW
Langan developed repair plans for the site around the existing building to mitigate differential settlement. The existing building, currently occupied by Actelion Pharmaceuticals and managed by Jones Lang LaSalle, was constructed over ten years ago on the Sierra Point Landfill. The site experienced significant settlement relative to the pile-supported building resulting in the need for site improvements. Langan also worked with the owner to address concerns on the operation of the existing methane mitigation system.

Bayshore Technology Park

OVERVIEW
The one million-square foot Bayshore Technology Park exemplifies Langan's expertise with landfill redevelopment and the integration of our core engineering disciplines: site/civil, geotechnical, and environmental. We provide engineering design, permitting and bid/construction administration support for various site improvement projects throughout the campus. These site improvements support the flexibility and growth of the Park, which touts amenities that go beyond office space: fitness facilities, basketball courts, walking trails, and a Cal Train shuttle, among other amenities.

Hayward Library & Community Learning Center

OVERVIEW
Langan performed a geotechnical investigation for the City of Hayward Library & Community Learning Center, a 3-story, at-grade structure. The site measures 31,500 SF. We evaluated the site's subsurface conditions and provided conclusions and recommendations for the geotechnical aspects of the project design. During design, we consulted with the project team and reviewed the geotechnical aspects of the project documents. Since construction began in early 2016, our services have included observing over-excavation of undocumented fill beneath the foundation level, checking completed footing excavations, testing compaction of utility trench backfill, and checking building pad subgrade preparation.
