CTDOT Route 8 & I-84 Interchange – Value Engineering Study

Waterbury, CT

Commonly referred to as “The Mixmaster,” the Route 8/I-84 interchange consists of stacked viaduct structures, carrying Routes 8 and I-84 and a series of elevated ramp structures. This VE study evaluated the rehabilitation of eight bridges, a proposed temporary by-pass road used as a key element for the Maintenance and Protection of Traffic (MPT), and the use of a temporary U-turn as part of the planned detour proposal. The goal of the project was to extend the useful life of the structure for approximately 25 years—to allow for an interim fix—while the interchange was redesigned and rebuilt. The VE Team studied the As Given elements and developed proposals for five alternatives. A presentation was made to the client, and a VE Report was submitted. The VE Study was performed under Benesch’s 5-year task based services contract to provide constructability reviews, value engineering analysis and other related tasks associated with improving the quality of contract documents as part of the Department’s Quality Assurance initiative.
