Integrated Infrastructure Delivery Partners

Integrating Infrastructure to Drive Economic Development

About Us​

IIDP was founded by Larry Head, Len Dorr, and Leslie Fangman with a vision to build infrastructure that can drive economic development.
We don’t work in silos and look for projects with multiple utilities to integrate and elevate. Recognizing a market demand for preliminary
infrastructure studies crucial in promoting environmentally friendly construction and advancing projects to fruition, the trio embarked
on this venture. Bringing financing, multiple utilities, energy goals, policy and technology under one umbrella we can assess
assets and take would be waste and monetize it.

Distinguished as experts in the United States’ national Infrastructure sector, the organization is dedicated to shepherding both public and
private entities through project conception to delivery. Headquartered in Colorado, IIDP boasts a broad spectrum of project involvements
across the nation. IIDP has solidified its reputation as a dependable partner, assisting organizations in realizing their Infrastructure
projects. ​
