Hennepin County, Minnesota
The CSAH 53 (66th Street) corridor is nearly 4 miles long, spanning almost the entire width of the City of Richfield and extending into the neighboring City of Edina. This primary artery provides access to multiple commercial and residential districts throughout the city and includes Metro Transit stations. Additionally, the corridor serves as a major pedestrian route, connecting prominent public spaces located within the surrounding communities. The corridor had deteriorated pavement; aging and undersized watermain, sanitary, and storm sewer facilities; and outdated signal, lighting, and pedestrian accessibility features.
Bolton & Menk partnered with several local firms to provide construction administration services for the $37 million federally funded project, which included proactive construction for part of the Orange Line southbound I-35W/66th Street station. The project included an emphasis on maintaining public access and preserving relationships with the impacted community. The construction team coordinated public outreach efforts from multiple project partners to successfully manage relationships with the public, ensure access was being maintained, and deliver a unified message spanning multiple social media platforms.
Under Bolton & Menk’s lead, the construction administration team took a synergistic approach to generating construction documentation and establishing QA/QC procedures to ensure documentation met federal funding standards. We also ensured the project stayed on schedule by tracking and managing the review process of more than 100 submittals, mitigating risk through detailed plan reviews, carrying-out value engineering changes, coordinating private utility schedules and sequencing, and providing in-field design revisions to lessen utility conflicts and construction delays. Through active and consistent coordination efforts, construction met contract schedule milestones and remained within budget.
The result was new multimodal infrastructure that includes 3.5 miles of 3- to 4-lane divided roadway; 63,000 lineal feet of concrete curb and gutter; 430,000 square feet of concrete sidewalk, cycle track, and driveways; 78,000 lineal feet of underground utilities, including sanitary, watermain, and storm sewer facilities; 2 new roundabouts and an at-grade railroad crossing; traffic signal and lighting system improvements; and pedestrian facilities meeting modern ADA requirements.
