Indian River Coinity Page 3 <br /> .Schumann Drive and Barber Street Intersection Improvements Project No. PSL - O8-2754 (BG 11 . l) <br /> Mast Arms <br /> 1 . Explore the subsurface conditions at the intersection with 3546ot deep SPT borings <br /> drilled at diagonally opposite corners (if feasible) . <br /> Laboratory Testing <br /> 1 . Laboratory examination (classification) of the material samples and physical property <br /> tests of same to establish their plasticity , gradation , organic content , moisture content , <br /> LBR and corrosion potential . <br /> Reporting <br /> 1 . Preparation and submittal of a report that presents results for the roadway soil survey <br /> and structures investigation as detailed in Chapter 9 of FDOT' s Soils and Foundation <br /> Handbook (2006) . The report will address plastic and/or organic soil limits , if <br /> present, projected water table levels , and design/construction options to deal with <br /> plastic/organic soils and perched water (e . g . , medians) . The report will include cross - <br /> sectional profiles of the subsurface conditions with soil classifications . <br /> Our geotechnical budget does not include costs for rental of earth moving equipment to access <br /> heavily vegetated or un - level terrain areas . Our intent will be to adjust the boring locations so as <br /> to avoid the need for clearing activities . <br /> Where necessary, we assume that access to the roadway alignment through private properties <br /> will be coordinated by the County . <br /> We strongly recommend that the project surveyor survey the horizontal and vertical positions <br /> of the borings and piezometers. This data (elevations) is key to establishing cut depths for <br /> unsuitable soils and the seasonal high groundwater levels (elevations). <br /> SCHEDULE <br /> Following receipt of your written authorization to proceed , we estimate that our schedule for the <br /> geotechnical work will be as follows : <br /> • Project start- up , boring layout and utility clearance — l week <br /> • Field exploration — 1 week <br /> • Laboratory testing — 1 to 2 weeks <br /> • Engineering analysis , preparation and submittal of draft report — 2 weeks <br /> • Finalize report - 1 week <br /> SCHEDULE TOTAL : 6 to 7 weeks <br /> DUNKELBERGER <br />
