Description

Alliant provided the Maintenance of Traffic (MOT) and environmental compliance/SWPPP design on this $239 million, 4-year Design-Bid-Build construction project as part of the Ames Construction Team. The project reconstructs 3-miles of interstate through the heart of downtown Minneapolis, including the interchange between I-35W and I-94, and carries an ADT in excess of 200,000 on I-35W and 250,000 in I-94. Major elements include full-depth reconstruction and concrete paving of I-35W mainline, adding northbound and southbound MnPASS lanes, full reconstruction of three complex urban interchanges, reconstruction of 11 cross or side streets, adding bus rapid transit stations, and nose wall construction. The project also included the construction of 22 bridges and installation of Intelligent Transportation Systems (ITS) to facilitate the future MnPASS lanes.

As the MOT Manager on the Ames Team, Alliant is responsible for reviewing bid plan set traffic control and staging plans to identify opportunities for safety, efficiency, schedule, and operational improvement. In addition, Alliant performs site reviews to ensure traffic control is installed correctly, generate solutions to traffic capacity deficiencies, and identify potential safety risks to the traveling public. Alliant also oversees the production of all staging and traffic control plans that are required due to Contractor requested deviations from the bid documents.

As the SWPPP Designer on the Ames Team, Alliant is responsible for generating all SWPPP amendments and conducting quality assurance audits of in place BMPs to recommend opportunities for improvement to the Project team.
