SEAMASS was established under the auspices of the Boston Association of Structural Engineers (BASE) in May 2006.

The goal was to create an organization for individual structural engineers to have an opportunity to experience the structural engineering profession in Massachusetts, benefit from locally provided technical education, and to act as the Massachusetts member organization for the National Council Structural Engineers Associations (NCSEA)

When the NCSEA was established in 1993, BASE, a group whose members represent their structural engineering firms, became the Massachusetts member organization of NCSEA.

However, the majority of NCSEA state-representative organizations are associations comprised of individual members.  Realizing this, and seeking to provide individual structural engineers with access to the benefits of NCSEA, BASE voted to approve the formation of the Massachusetts Institute of Structural Engineers (MISE) in early 2005. The MISE subcommittee consisted of BASE President Arthur MacLeod (Chair); Charles Pustizzi, PE; Cindy Chabot, PE;  Ed Moll, PE; and Wayne Lawson, PE.  In 2006, this subcommittee recommended that BASE rename the organization to SEAMASS.

SEAMASS became the Massachusetts representative to NCSEA. BASE helped to develop the SEAMASS bylaws and provided initial funding to implement the new organization. All of the firm representatives of BASE became the first members of SEAMASS and the first slate of officers came from the BASE membership.

The Boston Association of Structural Engineers (BASE) provides a business forum for structural engineering firms practicing vertical construction projects.  Initially limited to firms within a twenty five mile radius of the Commonwealth of Massachusetts State House, its membership is now open to all structural engineering firms in the New England states.  Its purpose is to explore and address the business and professional issues that affect these firms.  Its bylaws and budget are separate from those of SEAMASS.
