Project Overview
As part of the continuation from the 2013-2015 Hoan Construction project, Collins was retained by the Wisconsin Department of Transportation to provide construction management and inspection on two construction projects: Hoan Paint and Hoan Landscaping. Both were two-year contracts. The bridge crossed over two local city streets and then ran over a city street for approximately half of the project length. The bridge was also located over facilities for the Port of Milwaukee. The contractor used underdeck bridge mounted platforms to act as containment and allow for access under the bridge.
The paint project consisted of removing and capturing for proper disposal the existing lead based bridge paint system via blasting, and installing a new three-coat paint system on Structure B-40-400, units S5 to S24. As part of the previous Hoan Construction project, similar paint related work was completed on units S4 through N4, including the main span arch.
WisDOT utilized a three-coat paint product consisting of an organic zinc-rich epoxy primer, with an epoxy second coat, and polyurethane pigmented top coat. Work continued in the field with an expected winter shut-down starting near the end of November. Construction resumed in the spring and the contract completion date was November 30, 2017. Because of corrosion damage to the exterior girder and stiffener, Collins coordinated structural steel retrofit details for implementation by the contractor.
An existing underdeck lighting system had high pressure sodium light fixtures that were replaced with LED.
The landscaping project involved installing landscaping, an irrigation system, and decorative lighting along the I-794 corridor where it passes over local roads in the City of Milwaukee. Due to coordination with an adjacent construction project, only approximately half of the assigned work could be completed in 2016. The project waited until spring 2017 to install the remaining landscaping work. Once installed, there is a plant establishment/proving period that extended to October 2018. Collins provided all inspection and management on the project.
