A. Reconnaissance and Planning 1. Upon receiving authorization to proceed, Rii will retain a permit for soil borings within the right-of-way from the City of South Bend and/or St. Joseph County, as applicable. 2. A representative from Rii will perform site reconnaissance and mark all boring and pavement core locations in the field. The borings will be marked using white ribbon on wood lath or white paint in the pavement. During the field reconnaissance, the geotechnical engineer will document site geological conditions and map all boring locations. Rii utilizes a handheld GPS unit delivering sub -foot accuracy to locate soil borings. GPS coordinates of the boring locations will be acquired during field reconnaissance, along with the established project benchmarks. If benchmarks are not available, Rii will establish reference points at the site. 3. Rii will contact Indiana 811 at least 48 hours prior to drilling, as a standard precautionary measure for locating site utilities. It is requested that ASI or the City of South Bend supply to Rii any utility information they may have with respect to the proposed boring locations. 4. It is considered that the boring locations will be accessible to a truck or all -terrain vehicle (ATV) mounted drill rig, and that most of the boring / core locations will be located within existing right-of-way. However, within the limits of pavement improvements near South Bend Farmer's Market, access to private properties will be needed. As such, time has been allotted to prepare and distribute property owner notification letters to all entities that will be impacted by the geotechnical operations. B. Field Program 1. A drilling program was requested by ASI, consisting of a total of thirteen (13) roadway borings, designated as RB-1 through RB-13, within the project limits, along various roadway alignments, extending to depths varying from 15.0 to 20.0 feet below the existing grade. Please note that, since the proposed roadway improvements were unknown at the time of preparation of this proposal, roadway boring depths may be deeper than typical IGM requirements. Actual boring depths will depend on the conditions of the soil encountered. For the purpose of this proposal, a total drilling depth of 210.0 feet of soil sampling and no rock has been estimated.
