CENTRAL UTILITY PLANT RENOVATION
SACRAMENTO, CA

The Central Plant Renovation project is a Design-Build effort by Nacht & Lewis + Skanska to upgrade the current 35,000 square foot plant (built in 1967), which provides chilled water (for cooling) and steam (for heating) to more than five million square feet. The new design called for an 80,000 square foot central plant and six million gallon thermal-energy storage tank. Skanska obtained LEED Platinum rating for this project.

MatriScope provided all special inspections and material testing services related to portland cement pervious concrete pavement, cast-in-place concrete, reinforced masonry, structural steel and buckling-restrained braces.

SMUD SOLANO WIND FARM PHASE 3
RIO VISTA, CA

Phase 3 of the Solano Wind Projects primarily consists of the manufacturing construction and installation of 55 Wind Turbine Generators (WTG) for SMUD. The generators consist of up to 128 MUI of WTG net capacity, including associated SCADA and other ancillary equipment and service. Construction at this phase will be built on District-owned land (4,244 acres) located in the Montezuma Hills region of Solano County. Additional site work includes new roadways (across roads), O&M building, power collection systems (circuits), utility crossings (transmission lines) and two meteorological towers. 

MatriScope was selected to perform special inspections and material testing services, including earthwork, cast-in-place concrete, reinforcing steel, high strength grout, structural steel, and bolting.

SUNPOWER OASIS GROUND SYSTEM—PHOTOVOLTAIC ARRAY
CHINA LAKE, CA

SunPower Corporation has begun construction on a 13.78 megawatt solar photovoltaic power system at the Naval Air Weapons Station in China Lake, California. The high efficiency solar technology promises to generate the equivalent of more than 30 percent of China Lake’s annual energy. The installation of this system producing emission-free solar power is projected to reduce costs by $13 million over the next 20 years.

MatriScope was selected to perform special inspections and material testing services related to earthwork, including field compaction, testing, and observation, cast-in-place concrete consisting of rebar and hold down inspection and concrete placement and sampling, and structural steel.

WEST SACRAMENTO SOLAR FIELD
WEST SACRAMENTO, CA

The proposed West Sacramento Solar Field project will take place at four separate sites along a 3-mile long, 500-foot-wide strip of property. The scope of the project includes the construction of 1,928 isolated concrete mat foundations (13-feet in diameter and 2-feet in depth) to support the solar panels as well as the installation of one utility pole each at three of the four sites, and an underground 3-inch diameter conduit with conductors across each site.

MatriScope provided geotechnical investigation services including the exploration of the subsurface conditions utilizing 19 soil borings to a maximum depth of 15 feet, and laboratory testing of selected representative samples obtained during the field investigation to evaluate relevant engineering parameters of the subsurface soils. In addition, MatriScope provided engineering analyses on recommendations for the design and construction of the geotechnical aspects of the project.

RIVER CITY HIGH SCHOOL PHOTOVOLTAIC ARRAY
WEST SACRAMENTO, CA

The Solar Photovoltaic Array system is a Design-Build contract project to reduce daily energy consumption for the high school and recreation center buildings, as well as provide reliable power and diminish long-term  energy costs with minimal environmental efforts. The scope of the project includes installation of 450 PV panels, drilled piers, inverters, and a monitoring system.

MatriScope provided special inspections and material testing services related to earthwork and cast-in-place concrete.

CLIF BAR HEADQUARTERS SOLAR ROOF
EMERYVILLE, CA

The Clif Bar Headquarters Solar Roof was a design-build project, aimed at optimizing output and reducing costs, consisted of installing a 530 kilowatt “smart-solar” photovoltaic array on the roof and parking structure of the 115,000 square foot  building. Over 1,900 in count, the photovoltaic modules are anticipated to provide nearly 100 percent of the headquarters’ electricity needs. The company sought a LEED-Platinum certification for the project.

MatriScope provided all special inspections and material testing services related to cast-in-place concrete including hold-down inspection and fiber-reinforced panel installation, and structural steel fabrication and erection.
