Summer Membership Referral Promotion

Calling all ISI members! Do you know a company that would benefit from a membership with ISI? Our members represent a unique network of architecture, engineering, and construction professionals across the public, private, and academic sectors. We’d love for you to share the benefits of ISI membership with other companies that align with our goal of creating more sustainable, resilient, and equitable infrastructure. Plus, for the month of July, there are even more benefits!

When current ISI members refer a new corporate member in July, both firms will receive a one-month membership extension when the new member joins! This extension will be added to your annual memberships. To make a referral and take advantage of this offer, fill out the form below and our membership team will follow up with you and your referral contact.

If you have landed here and you are not already an ISI member, but you are interested in membership and have been referred by a current ISI member, click here.
