The $2.6 million Chicago Department of Water Management‘s (CDWM) West Rogers Park sewer improvement project in Chicago’s Lincoln Square and West Ridge neighborhoods, required the removal of the existing 72” RCP storm sewer and installation of a new 72” wye RCP storm sewer at the intersection of W. Peterson Ave. and N. Fairfield Ave. The contract also required coring an existing 72” RCP storm sewer to install a 30” DIP at the intersection of W. Farwell Ave and N. California Ave. Also, installation of 2,900 ft of 24”-36” reinforced concrete pipe on W. Farwell Ave from N. California Ave to N. Washtenaw Ave, N. Washtenaw Ave from W. Farwell Ave to W. Coyle Ave., N Fairfield Ave from W. Peterson Ave. to W. Thorndale Ave., and W. Thorndale Ave. from N. Fairfield Ave. to N. Rockwell Ave. Along with the storm sewer, the contract required installation of many City of Chicago drainage structures (CB, Ty A MH, Tumbling Basin, and Ty B MH), concrete collars, concrete pipe saddles, roadway drain connections, and residential personnel drain connections. In areas where the storm sewer crossed existing 8” or 12” water mains, the water main was structurally supported or cut and reconnected. The site was restored using concrete base course within sewer trench limits, asphalt surface milling and resurfacing from the edge of the curb to edge of the curb, removal, and installation of curb and gutter, removal and replacement of existing sidewalks (per ADA requirements), thermoplastic pavement markings and landscape restoration. The work was performed under a complete detoured closure on N. California Ave. and W. Farwell Ave. and EB lane shift on N. Fairfield Ave. and W. Peterson Ave.

The contract for the CDWM sewer improvement project in West Rogers Park required ongoing coordination with Chicago Department of Water Management PM, CDWM Mason Inspector, General Contractor, CDWM Watermain Inspector (CTR), CDWM Watermain Designer, City of Chicago Transportation Permits, IDOT MOT Permits, 40th Ward Alderman, 50th Ward Alderman, CTA, and Lincoln Square and West Ridge residents. Cotter maintained coordination with Lincoln Square and West Ridge residents through city flyers, face-to-face conversations with residents, and providing up-to-date project status to the 40th and 50th Ward Alderman. Cotter used a drone to coordinate with CDWM PM, CDWM Inspector, and Designer to resolve ComEd and 72” RCP storm sewer conflict at W. Farwell Ave. and N. California Ave.
