S. Government. We have a rich history of tackling diverse construction jobs across Southern California and in other states. Take a look at some of our key commercial projects in the region:

BUILD SOLAR POWER GENERATION SYSTEM AT SEVERAL COUNTY OF SANTA CLARA FACILITIES PROJECT

The County of Santa Clara selected Stronghold Engineering, Inc. to provide cost effective, solar photovoltaic electric generating systems for several facilities located within Santa Clara County. The combination of roof top, carport and ground mounted systems is now providing more than 5MW of power for the County. The project was part of the County of Santa Clara’s multi-jurisdiction renewable energy procurement effort; said to be one of the largest in the US in terms of the number of sites and cities participating. Design started in February of 2011, ground broke in July 2011 and the project was successfully completed in April 2012.

INSTALL PHOTOVOLTAIC SYSTEM, SEAL BEACH PROJECT

Stronghold Engineering, Inc. served as the prime contractor for this $2.3M fast-track design-build project to install Solar Photovoltaic Power Systems (SPVPS) for two (2) buildings at the Naval Air Weapons Station in Seal Beach, CA. This project was part of the American recovery and Reinvestment Act (ARRA) of 2009, which aims to reduce carbon footprints through renewable energy. The SPVPS was installed on the roofs of each building which included demolition and replacement of each roof system. Each SPVPS supplies power to the building and feeds energy back into the power grid if/when there is an excess of electricity produced. The SPVPS consists of multi-crystalline photovoltaic modules, inverters, a monitoring system, combiner boxes, a racking system, a mounting system, a housekeeping pad, sunshade and fence.

INSTALL PHOTOVOLTAIC SYSTEM, NAVAL BASE SAN DIEGO PROJECT

Stronghold Engineering, Inc. served as the prime contractor for this $2.6M fast-track design-build project to install Solar Photovoltaic Power Systems (SPVPS) for three (3) buildings at the Naval Base in San Diego, CA. This project was part of the American recovery and Reinvestment Act (ARRA) of 2009, which aims to reduce carbon footprints through renewable energy. The SPVPS was installed on the roofs of each building which included the demolition and replacement of each roof system. Each SPVPS supplies power to the building and feeds energy back into the power grid if/when there is an excess of electricity produced.

PHOTOVOLTAIC SYSTEM AT INSTALLATION RESTORATION SITE 7, BOX CANYON LANDFILL PROJECT

Stronghold designed, procured, and constructed a complete solar photovoltaic system including balance of system components, electrical utilities, communication utilities, monitoring and metering, utility equipment building, and associated equipment and devices to occupy the approximately six (6) acres of closed landfill space. The design and construction approach to this project offered a solution that minimized impacts to the integrity, function, and useful life of the Evapotranspiration cover of the landfill. In addition, Stronghold presented the Navy a comprehensive schedule that showed successful completion in less than the required 465 calendar days while adhering to all requirements delineated in the Request for Proposal.

ROYBAL federal BUILDING and u.s. courthouse

Stronghold Engineering and CannonDesign teamed to provide extensive repair and alterations to 12 floors of the Edward R. Roybal Federal Building and U.S. Courthouse in downtown Los Angeles. The work involved repurposing existing courtrooms and renovating existing court-occupied space for general office space assigned to the U.S. Bankruptcy Court (USBC), the U.S. District Court (USDC), and Pretrial Services. Relocation of the Circuit Library with an all new design is a major feature of the design. The project was constructed in five phases over the course of 18 months.

COMPREHENSIVE SEISMIC & LIFE SAFETY RENOVATIONS IN THE BASEMENT FEDERAL BUILDING PROJECTS

This design-build project called for Comprehensive Seismic and Life Safety Renovations for the basement and floors 1–8 of the Federal Building in downtown Los Angeles, California. The project included upgrading of life safety systems, seismic strengthening, and modernization. This very challenging project called for occupants to remain in the building as work was phased and completed. The Project Team worked very closely with the client to minimize impact from construction activities for this 1.2 million square foot construction project in this fully operational, occupied space.

Building Stronger Communities

At Stronghold Engineering, we owe our success to the assistance of others. That’s why we believe in paying it forward.

Community Engagement

Our team is dedicated to helping those in our community who need assistance. We’ve partnered with Lamb Energy to install photovoltaic systems at no charge to several area churches. Employees have donated their time and hard work to raise funds to support community organizations like Loma Linda University Children’s Hospital, Blindness Support Services, Inc., Harvest Ministries, Grove Community Church, and many others.

As a California construction company, we want to help our community by doing what we do best: local building projects.

A few years ago, our neighboring elementary school was in need of an outdoor venue for assemblies and performances. Stronghold and our employees donated time and our vendors provided free materials to make the school’s new amphitheater a reality. Working with the local Boy Scouts, this initiative even helped one Eagle Scout complete his required project. We’re proud to use our skills as a California construction company to support our community.
