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


Since 2020, ISI and the Mexican Federation of Professional Civil Engineers Federación Mexicana de Colegios de Ingenieros Civiles, or FEMCIC have been collaborating to extend the Envision framework into Mexico. View the announcement.


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


In Spain, ISI signed a collaboration agreement in May 2022 with Tecniberia (The Spanish Association of Engineering, Consulting and Technological Services Companies), and the Colegio de Ingenieros de Caminos, Canales y Puertos (CICCP) (Spanish Council of Civil Engineers). Read the news post.

East Africa

ISI signed an agreement in October 2022 with the Miundo Misingi Hub to advance sustainable infrastructure in East Africa. Based in Nairobi, Kenya, the Miundo Msingi Hub is an independent professional body comprised of infrastructure development practitioners from the public and private sectors, academia, and civil society organisations.
