We have enormous respect for the excellence and efficiency of the subcontractors we choose to partner with. It’s just one of the ways we uphold the best relationships in the industry.

We see our subcontractors as part of our team. We work with the best in the business to ensure quality and integrity in all our interactions.

In Diversity We Build Strength

Since our founding, Buch has been dedicated to working with a diverse group of individuals, both on our team and in our community of suppliers and subcontractors. We are a woman-owned business, and it is important to us to support other woman- and minority-owned businesses.

As the industry has evolved and Buch has grown, we have made it our business to seek out qualified diverse subcontractors and suppliers. We actively engage them in the procurement process, offering feedback and support. While we of course work to meet clients’ diversity spend goals, we have a pool of diverse/woman-owned vendors who we return to again and again, regardless of project-spend requirements.

We are actively involved in the Women’s Business Enterprise National Council (WBENC) and are continually looking for ways to do our part to increase supplier diversity, at Buch and throughout the industry.

We’re proud of our history, our commitment to diversity today, and our ambitions for the future. Diversity makes us all stronger.
