About our company
Gonsalves & Stronck Construction Co., Inc. was founded in 1993 by Keith Gonsalves and William Stronck as a construction management and general contracting firm serving both the public and private sectors in the Greater San Francisco Bay Area.
From the beginning, Keith and Bill drew on their unique combination of industry experience and comprehensive project management to form a solid foundation for Gonsalves & Stronck Construction. Today, they continue to complement their firm’s strengths and diversity by employing a core group of talented individuals who share their commitment to quality building, embrace new challenges and techniques, and take pride in developing and enriching our Bay Area communities.
While taking on new projects of differing scope and complexity every year, our primary emphasis over the last decade has been in new construction and renovation of commercial facilities. This includes office improvements, research laboratories, essential-services facilities, recreation, seismic retrofit, educational facilities and municipal buildings.
No matter the size or scope of a project, our clients can expect quality construction and comprehensive project management throughout all phases of work. We strive to foster a positive environment of open communication with the design team and client and proactively work to identify and resolve issues before they become conflicts. Our project teams utilize the most efficient and up-to-date industry techniques and put problem solving and value engineering to work from preconstruction to closeout.
