TAI completed Plans, Specifications and Estimates (PS&E’s) and performed construction observation for the City of North Chicago’s 2015-2016 streets rehabilitation and water main replacement program. TAI designed water main replacement for 6,100 feet of existing 6-inch, 8-inch and 12-inch water main and designed street rehabilitation for 8,900 feet of streets ranging from grind and overlay to rubblization of existing concrete bases of select streets.
During design, differing methods of resurfacing and rehabilitating streets were investigated. In-place recycling, full depth reclamation (FDR) and typical grind and overlay were analyzed for various streets in the program to determine the most cost effective options.
Work included raised island removal at Dugdale Road and Argonne Drive, conversion of concrete medians into landscaped medians, IDOT utility and IEPA permitting, ADA compliance for curb ramps, curb and gutter replacement and surveying.
Funding sources for the project were CDBG and MFT. Construction cost for the program was $3.1 million.
