GB Construction has been helping Garden Grove Unified modernize schools since 2012.  GB is responsive to owner directed changes, tight schedules, keeps change order costs down, and worker craftsmanship meets our expectations.  Modernization projects always have unforeseen issues and GB takes a proactive approach, recommending cost effective solutions while keeping the project on schedule. 


Most importantly, GB is sensitive to the needs of the school site administration and ensures that the construction site is clean and fenced, and halts noisy work during testing or other special school events.  GB’s willingness to work as a team player while completing the project on time makes it easy for me to recommend GB to my school district colleagues.

G.B. Construction safely and expeditiously completed the campus-wide modernization project at Corvallis Middle School with professionalism and dedication. It was a pleasure to work with a general contractor that took such great pride in their finished product.

Moreover, one of the project highlights was that G.B. Construction completely modernized (demolished down to the studs and rebuilt) the administration and multi-purpose buildings within the 68 days of summer recess. This accomplishment received the highest level of praised from teachers, students and staff because it facilitated an uninterrupted education process.

Lastly, G.B. Construction’s responsiveness to any and all warranty related concerns is unparalleled in the K-12 construction arena. I sincerely recommend G.B. Construction for your current and future projects.

Contractors & Developers Bonding

Building 106 efficiency units for low- and very low-income individuals, including some who are often homeless, over a ground level of supportive services, landscaped common areas, community spaces and retail tenants in a new, Type III, LEED Platinum, six-story, mixed-use building in the heart of downtown Los Angeles will always present difficult challenges. Such was the case for the New Genesis Apartments developed by Skid Row Housing Trust and designed by Killefer Flammang Architects (KFA).  GB Construction, Inc. was hired to be the general contractor.


As a member of the KFA architectural team, it was on this project that I was introduced to GB Construction, Inc. I enjoyed working with them on what could have easily turned into a contentious experience for all involved. Since the Owner, Architect, Builder and Construction Manager were always focused on the same goal this never was allowed to happen. There was always an effort and desire to deliver a quality product within a given budget and schedule.


From pre-construction to project close-out, I found the staff at GB Construction, Inc. to be professional, fair, responsible team players and knowledgeable problem solvers. They seemed to have good relationships with their subcontractors who were also competent. I have recommended them for other projects and will continue to recommend them to others and will look forward to working with them again on future projects.
