SCOPE OF SERVICES PRELIMINARY GEOTECHNICAL INVESTIGATION SOUTH BEND MARKET DISTRICT IMPROVEMENTS PROJECT CITY OF SOUTH BEND, INDIANA RII PROPOSAL NO. 23-1086 The following scope of services and cost estimate have been prepared in accordance with the information published in the Indiana Department of Transportation's (INDOT) Request for Proposal (RFP), through Local Public Agency (LPA) program, project #123-053, and information provided via e-mail as well as over the phone conversation with Mr. Eric Farny, P.E., with American Structurepoint, Inc. (ASI), between October 13 and November 6, 2023. This proposal has been prepared in accordance with the 2021 INDOT Geotechnical Manual (IGM) and the 2013 INDOT Design Manual (IDM). The project is understood to consist of study and design of the improvements within the entire Market District, in the City of South Bend, Indiana. As per the information received, the scope will be divided in to two (2) phases: Phase 1 will consist of improvements east of the St. Joseph River, and Phase 2 will comprise roadway and bridge improvements, west of the St. Joseph River. It is to be noted that this proposal considers this scope to be a preliminary limited subsurface investigation for Phase 1 of the project, so as to understand general site conditions. Upon receiving the Stage 1 design information, a detailed and separate, scope and fee proposal will be submitted to cover the proposed improvements within the entire corridor. Based on the information received the project the existing ramp from East Mishawaka Avenue to SR 23 will be eliminated, and that the existing East Branson Street, as well as East South Street will be extended to Northside Boulevard. Further, the Mishawaka Avenue extension will include a new roundabout at the intersection with South Eddy Street. The above improvements will result in new roadway alignments throughout the project limits. The existing SR 23 and Mishawaka Avenue roadways within the project limits are asphalt paved bidirectional roadways with two lanes in each direction of travel. Full width outside shoulders along the majority of these roadway alignments are present. The existing remaining roadways — including East Branson Street, East South Street, Belmont Avenue, South Eddy Street, Beyer Avenue, and Northside Boulevard — are two-way, bidirectional, asphalt paved roadways, without outside shoulders. For the above proposed improvements, as requested by ASI, this proposal considers the fieldwork to include limited roadway borings, pavement cores, topsoil sampling and 24-hour extended groundwater observations at selected locations. This proposal is prepared based on the consideration that all soils and groundwater are free of hazardous materials and/or petroleum products, and no personal protective equipment (PPE) will be necessary beyond which is required for the drilling operations (EPA Level D). If any such conditions are encountered during the field investigation, the client will be notified immediately, and the field program will be stopped until corrective actions can be performed.
