Intelligent Infrastructure Systems Overview

Intelligent Infrastructure Systems works with owners to assess infrastructure using advances in information, sensing, and communication technologies that have developed over the past decade. Intelligent Infrastructure Systems offers world-class applications of the most reliable monitoring, modeling and decision tools and techniques, together with the engineering support and experience of a highly respected engineering firm, to aid infrastructure owners such as state DOT’s, local municipalities and toll bridge authorities as they preserve and renew their key assets. By gathering real time information on actual live loads and recording the reaction of the structures, Intelligent Infrastructure Systems derives a maintenance and/or renewal plan that focuses on performing the retrofit or intervention in a targeted manner and helps infrastructure owners to focus the rehabilitation, renewal, and preservation efforts on the precise areas of the infrastructure inventory that need it the most and that will provide the most beneficial return.
