For this phase III IDOT project the work included the replacement of the Bridge which carries Central Street across the North Shore Channel in the City of Evanston in Cook County. The scope of the project included replacement of the existing three span structure with a 168 foot long and a 77-foot-wide single span bridge. Responsibilities included the bridge deck concrete placement and ensuring the results met the project plans and specifications. INTERRA, as a subconsultant to Stanley Consultants, conducted testing and inspection on both asphalt and concrete in the field. INTERRA covered pavement, curbs, gutters, light pole foundation, pile encasement, slabs, and abutments. INTERRA also provided Construction Inspection services for the project. Specifically, INTERRA oversaw the installation of bridge abutments. For asphalt INTERRA verified the density and temperature results. Concrete testing consisted of slump, air content, temperature, and strength. INTERRA also cast cylinder specimens which were transported to the INTERRA laboratory.
