Design Build of the New Mississippi Outfall, Denver, Colorado
This paper presents an overview of the design-build of the New Mississippi Tunnel Outfall for the Transportation Expansion Project (T-REX). The Contractor was Southeast Corridor Constructors (SECC), a Kiewit-Parsons, Joint Venture. Parsons acted as JV partner as well as designer and provided a unique perspective in the design build setting. The Transportation Expansion Project's New Mississippi Outfall is a $30 million constructed value project. This is a small but important part of the 1.2 billion dollar highway widening and Light Rail Transit (LRT) expansion project of Denver's Interstate Highway I-25. The Outfall conveys highway and other urban drainage to the South Platte River as well as provides long needed relief from flooding problems in the southeastern portion of the Interstate 25 highway corridor. The Outfall tunnel conveys storm water under I-25 then under Mississippi Avenue to the river. The Outfall consists of a number of distinct elements with water flowing and connecting from east to west as follows: an Energy Dissipation Structure, 91 m of 213 cm diameter jacked pipe crossing under I-25, Junction Interceptor Structure, 554 m of 4 m ID tunnel excavated by earth pressure balance machine technology, a Transition Structure (connecting the circular section to a rectangular section and serving as the main tunnel driving shaft), 266 m of 5.5 m wide by 2.4 m high cut and cover box structure, and Outfall Structure at the South Platte River.
