Bristol Alliance of Companies

Whether working independently or collaborating across multiple service lines, each Bristol company provides high-quality projects from concept through completion. This commitment has led to long-term relationships and an impressive track record of diverse projects. With the ability to provide specific expertise or integrate a full range of capabilities, Bristol companies will cultivate project solutions for clients that are effective, innovative and value-driven.

Bristol companies provide a range of services, including civil, structural and mechanical engineering; heavy, civil and vertical construction; environmental remediation; fuel systems; range and unexploded ordnance response services; electrical and telecommunications services; and demolition and site preparation services throughout the United States, its territories and select international locations. Each company is a wholly owned subsidiary of Bristol Bay Native Corporation.

BBNC owns a minority interest of the Bristol companies, with Choggiung Ltd., a Dillingham-based village corporation, owning a majority interest in the companies. Read about this groundbreaking partnership by clicking here.
