ISI Partners & Members

ISI Founders

The following associations were instrumental in ISI’s formation in 2010. To this day, they are integral supporters of Envision and work closely with ISI to advocate for Envision in North America.

American Society of Civil Engineers  (ASCE)
American Public Works Association (APWA)
American Civil Engineering Companies (ACEC)

Research Partner

APWA, ASCE, and ACEC collaborated with the Zofnass Program for Sustainable Infrastructure at the Harvard University Graduate School of Design to develop Envision. ISI continues to work closely with the Zofnass Program to this day.

Global Partners


In Italy, the Envision credentialing and verification programs are administered by ICMQ through Envision Italia. ICMQ (Institute for Certification and Quality Branding for Products and Services for Construction) is a non-profit association that encompasses numerous sector associations operating in every part of the construction industry.


In 2020, ISI also signed a partnership agreement with the Federación Mexicana de Colegios de Ingenieros Civiles A.C. ( FEMCIC ) to bring Envision to Mexico.


In 2021, ISI also signed a partnership agreement with the Canadian Society for Civil Engineering (CSCE) to accelerate the use of Envision to Canada.
