UC Merced – Campuswide Expansion

OVERVIEW
The UC Merced 2020 Expansion is an unprecedented four-year project that nearly doubled the physical capacity of the campus, allowing it to grow to 10,000 students and expanded it to 219 acres. The P3 project required extensive scheduling in order to be completed by 2020. Scheduled in three delivery phases, the expansion included 16 buildings, two bridges, new roads and parking lots, and several athletic facilities and fields. Construction challenges involved building two facilities in a reclaimed part of Little Lake and constructing two bridges crossing Fairfield Canal, an unlined irrigation canal that snakes around the campus.

UC Berkeley – Cal Aquatics Center

OVERVIEW
Langan performed geotechnical and environmental investigations for the Cal Aquatics Center. Existing facilities were demolished to construct an Olympic-sized swimming pool, a dive tower, springboard platforms, and buildings for locker rooms, mechanical space, and storage. The University internal technical review panel approved all aspects of the geotechnical design. In our environmental investigation, we detected no contamination in the soil. Our results indicated that excavated soil could be disposed as an unrestrictive waste instead of at a regulated landfill.

UCLA Center for Health Sciences

OVERVIEW
Langan developed site-specific response spectra and time histories for the University of California, Los Angeles Center (UCLA) for Health Sciences. We performed probabilistic seismic hazard analysis (PSHA) and deterministic analysis to develop smooth, site-specific horizontal spectra for two levels of shaking corresponding to the Design Basis Earthquake (DBE) and Maximum Considered Earthquake (MCE).

UCSF Mission Bay – Sandler Neurosciences Center

OVERVIEW
The LEED Gold-certified Sandler Neurosciences Center is one of the largest neuroscience complexes in the world. Built on land reclaimed in the 1880s, the site was underlain by heterogeneous fill, weak and compressible Bay Mud, dense sand, and bedrock. For the new five-story, 237,000-SF building, Langan performed a geotechnical investigation, consisting of borings advanced to­ bedrock. We recommended pile foundations, below-grade walls, seismic design, utilities, and earthwork. Due to elevated methane concentrations in soil gas beneath the site, Langan designed the building’s methane mitigation system to prevent methane gas from intruding into the structure.

UC Berkeley – Hearst Greek Theatre

OVERVIEW
Langan performed a geotechnical investigation for the seismic upgrade of the 8,500-seat Hearst Greek Theater. Originally constructed in 1903, the Greek Theater consists of a seating area (bowl), a stage and stage colonnade, and support buildings. Most of the support buildings were added in 1957. The colonnade rises 35 feet above the stage and was constructed with un-reinforced concrete. Seismic improvements provide additional structural support to the stage colonnade and two end walls.

UC Davis Winery & Brewery Complex

OVERVIEW
The 34,000 SF Teaching and Research Winery and August A. Busch III Brewing and Food Science Laboratory is the first building of its kind to receive LEED Platinum certification. Our team evaluated soil conditions and recommended how to address the challenges of a relatively weak, compressible near surface layer, high floor slab and building foundation loads, and tight differential settlement performance criteria to maintain floor drainage.

UC Santa Cruz, Crown College – Major Maintenance & Accessibility

OVERVIEW
Located on a hilltop and surrounded by a redwood forest, the college includes eight residence hall buildings and eight apartment buildings. Per an agreement with the Division of the State Architect (DSA), UCSC needed to address site and interior access compliance for the eight facilities and one apartment building. Top priorities are receiving approvals from DSA and the Designated Campus Fire Marshall. Langan’s scope includes ADA/pedestrian site connectivity upgrades. Langan and the design team created more inviting open spaces that allowed for greater pedestrian flow through the site, decreased stormwater run-off, sized and upgraded utility lines, and relocated utility corridors to better fit the site. The Crown College project was designed to work towards the University’s net zero goals.

UCSF Mission Bay — Center For Vision Neuroscience

OVERVIEW
Plans for the new Center for Vision Neuroscience call for a 12-story building with 5-story south wing and a 3-story north wing. It will house ophthalmology clinics as well as teaching, research, conference, and administrative space. Langan explored subsurface conditions and evaluated existing data from explorations by others. The previous consultant recommended pile foundations, but we saved the team money by recommending ground improvement to allow for the building to be supported on shallow mat foundation. During construction, we observed installation and testing of displacement column ground improvement, site preparation, and other geotechnical-related construction items.

San Francisco State – Creative Arts Building

OVERVIEW
San Francisco State University plans to construct a Creative Arts replacement building and an associated future Center for the Arts and Media in the southern portion of their campus. The project is part of the University’s campus master plan, which is designed to provide facilities for expansion of academic programs to support increased enrollment and create a vibrant on-campus community. Langan provided geotechnical and environmental engineering services for the project.

CCSF Chinatown/North Beach Campus

OVERVIEW
The City College of San Francisco (CCSF) campus consists of a 14-story tower over a basement (main building) and a 4-story building over a basement (annex building). Langan performed a geotechnical investigation, geologic hazard evaluation, and site-specific seismic response study. We also performed Phase I and Phase II Environmental Site Assessments (ESAs) for the project. Our report was submitted to the Division of the State Architect (DSA) and CGS for review and was approved without exception. This project was the largest California community college and tallest structure to go through DSA.

Ohlone Community College

OVERVIEW
The Ohlone Community College Newark Campus is a brownfields redevelopment on an 80-acre site. This was the first LEED Platinum College Campus. In addition to our environmental characterization work and analysis of remedial options, we assisted the District with negotiating a voluntary cleanup agreement with the Department of Toxic Substance Control. The cleanup was integrated with the development plans, allowing cleanup to be completed concurrently with the site grading and foundation preparation. Our geotechnical team performed a master plan and design-level geologic hazard evaluation and geotechnical investigation. We performed our services in compliance with the requirements of the Title 24 California Building Code, Division of the State Architect (DSA) for community college projects, and California Geologic Survey (CGS) advising checklist (Note 48) for California Public Schools. Our reports were submitted to DSA and CGS for review and were approved without exception.

Santa Rosa Junior College – Culinary Arts & Student Services

OVERVIEW
The Culinary Arts Center consists of a 2-story, 25,000-SF steel-framed building with a slab-on-grade floor. The building footprint is about 15,000 SF.  The Student Services Center consists of a 1- to 3-story, steel-framed building with a slab-on-grade first floor.  The building footprint is about 75,000 SF. Langan performed a geologic hazard evaluation and geotechnical investigation for both buildings. Our geologic hazard evaluation and geotechnical investigation complied with the requirements of the California Code of Regulations, Title 24.

Modesto Junior College Expansion

OVERVIEW
Langan designed the vapor mitigation systems for four new buildings at the Yosemite College District’s (YCCD) Modesto Junior College campus. The new buildings include Allied Health Building, Pavilion, Community and Science Center, and Agricultural Housing. Our services included the design and construction observation of vapor mitigation systems, which consist of a sub-slab venting system and vapor barrier membrane in three of the four buildings, and a crawl space venting system in the fourth, to mitigate volatile organic compound intrusion into the indoor air. We are currently providing vapor mitigation services for the proposed greenhouse as part of the Great Valley Nature Lab development.
