BASE began in 1958 on behalf of structural engineering firms within a 25 mile radius of State House in Boston to work with what is today known as the Division of Capital Asset Management DCAM. In the late 1980s and early 1990s, BASE became of member organization of The National Council Structural Engineers. Some of the members of BASE have served as President of NCSEA in the early days of its creation. BASE then created SEAMass in 2006 to be the member organization of NCSEA to allow all structural engineers in Massachusetts access to improve the practice of structural engineering and to foster communication among structural engineers to improve the practice of structural engineering.

Today, BASE is made up of member firms around the State of Massachusetts and other New England states. It continues to serve its members who are mostly business owners. It also continues to provide service to the public in the form of education towards the public and its members to provide safe, long-lasting, and economical structures in the built environment.
