our commitment

Diversity & Inclusion

We believe that diversity shapes the best possible outcomes for our employees, clients, and community. Whether it’s an internal initiative or a complex project, the strongest results come from incorporating a diverse range of voices and perspectives.

People thrive when they’re allowed to be the best version of themselves. GCI is committed to nurturing a diverse and inclusive workforce that transforms our current landscape.

Subcontractor & Vendor Diversification

Improve the success of diverse businesses in the Bay Area and beyond by leveraging an action plan for subcontractor, peer partner, and supplier diversity. Strategically hire, promote, and support these businesses whenever possible.

Active Recruitment & Mentorship

Continue to expand recruiting efforts to diverse populations and nurture an environment of ongoing mentorship and growth within GCI. Create and maintain an environment where diverse talent can thrive.

Support for Underprivileged Communities

Provide support through hiring, employee development, and support of diverse businesses and entrepreneurs. Hire disadvantaged youth and help them grow their industry skills. Through our Madrone demolition company, we repurpose materials from jobsites that are given back to our community.


Minimizing Impact.
Maximizing Opportunities.

Our mission is to prove that protecting the environment and enhancing health and wellness is possible in the construction industry. Through collaboration and problem solving, we inspire our clients and partners and challenge the status quo.

For over 20 years, GCI has pioneered sustainable building practices in the Bay Area. We are always working to implement the most advanced ideas in green building and workplace wellness.

Our goal—whether we’re diverting waste from landfills, tracking materials, or pushing for new practices and standards—is to learn and grow alongside our partners.

Sustainable & Socially Responsible Demolition

We realized how much usable material and furniture was going straight to landfill, and we knew something had to be done. That’s why GCI started Madrone, our sustainable and socially responsible demolition company.

Madrone redistributes materials found on our projects to organizations and individuals in need. The program is donation-based; all materials are given back to our communities for free.

By partnering with Madrone, building materials can be salvaged or reused in their original form or recycled into new materials.
