A joint venture built on the strengths of two exceptional firms

Established in 2009, C3, LLC, (C3) provides diverse, quality design-build and construction services to customers nationwide through the talents and skills of more than 500 professionals. C3’s foundation is built on the decades of experience, successful past performance, and talents of two exceptional firms: Catamount Constructors, Inc., (CCI), and CTA Architects Engineers (CTA).

In 2009, C3 won a multiple award task order contract (MATOC) with the U.S. Fish and Wildlife Service (FWS). This contract has enabled us to work with various Department of the Interior agencies on a wide variety of design-build and construction projects totaling more than $150 million for the BLM, NPS, FWS, and BIA, among others.

With over 100 LEED Accredited Professionals on staff, C3 has become a leader in LEED certified construction. Our strong allegiance to green building practices began in 2003 when CCI became a member of the U.S. Green Building Council.

C3 delivers comprehensive design-build services from a single source to meet Government customers’ project needs. C3 specializes in IDIQ and similar contracts and has supported more than 100 IDIQ contracts over the past 25 years.
