Tasks, Schedule and Deliverables

This Exhibit A includes:


Glossary of Abbreviations

Definition of Terms

Task 1: Project Management

Task 2: Furnish and Install Automated Bridge De-icer

Task 3: Complete System Checkout

Task 4: Onsite and Off-site System Training

Task 5: System Documentation

Task 6: Warranty and Support Periods


CONTRACTOR will provide all necessary equipment, labor, part, supplies, and materials (except chemicals to be provided by the Minnesota Department of Transportation) for an automated bridge de-icer on both roadways of Interstate 35W Bridge No. 9340 over the Mississippi River in Minneapolis, Minnesota. CONTRACTOR will also provide necessary on site and off-site training of Minnesota Department of Transportation (Mn/DOT) operation and technical personnel for operation, trouble shooting, maintenance, and repair of the complete automated de-icer system. Installation and checkout of all project features will be completed by October 15, 1999.

Bridge 9340 has a history of many vehicle accidents due to traffic congestion on the bridge, the horizontal and vertical curvature of the bridge, "black ice" formation due to freezing vehicle exhaust moisture on the bridge surface and unique meteorological conditions at the bridge. This automated bridge de-icer project is intended to greatly reduce the number of vehicle accidents on the bridge and related property damages and threats to public health and safety and further demonstrate the technical, operational, and economic feasibility of fully automated bridge de-icer technology.
